	WARNING: do not use Pete Kaiser's emacs function "gs-toc" alone to
8 
	re-create the table of contents here, because it will replace the
9 
	hand-edited TOC subheads with a separate subhead for each H2 in
10 
	the body of the file.  Or if you do, first look at the original
11 
	TOC to see how to edit it for visual conciseness.

When ghostscript is given a PDF file on standard input, copy it to a

temporary file before processing. Prior to version 7, ghostscript could read
822 
PDF from standard input redirected from a file, but not from a pipe.
823 
Standard input was changed in version 7 to use callouts, which prevented PDF
824 
reading from standard input. Fixes SourceForge bug #583413, /ioerror with gs

Fixes problems:

	- adds a missing header to gxshade for indexed color routines.
856 
(lib.mak [1.103]: 2002/10/22 13:31:37 giles)
857 
	- update the ECHOGS_MAK dependency to ECHOGS_XE. (devs.mak [1.80],

int.mak [1.86], lib.mak [1.105]: 2002/10/22 18:38:00 giles)
859 
	- correct some dependencies against the include lists in the
860 
relevent C files. Also reorder them to facilitate easer checking next time.

865 
	- install the example FAPI configuration files by default. Ideally

867 
(unixinst.mak [1.28]: 2002/10/28 19:43:42 giles)
868 
	- provided a meaningful error message when an immediately evaluated
869 
name can not be found. Fixes SourceForge bug #543185, Confusing diagnostics
870 
for //undefined. (int.mak [1.91]: 2002/10/29 09:57:53 ghostgum)
871

872 
(unixinst.mak [1.29]: 2002/10/31 16:01:12 giles)
873 
	- Fiddles with makefile parameter quoting so that "make pg" runs
874 
again. (unix-end.mak [1.5]: 2002/11/02 05:51:00 raph)
875

Add real 'make distclean' and 'make maintainer-clean' targets. These are no

This is the first beta release in preparation for 8.0. A great many
1251 
bugs have been fixed since the 7.30 alpha release, and it should be
1252 
stable for most users. Two features planned for 8.0 are not yet fully
1253 
functional, however: subpixel positioning of antialiased text, and
1254 
Well Tempered Screening (the latter can be enabled for experimentation,
1255 
but does not work for 0 and 45 degree angles).

Fixes problems:
1405 
	- Mentions the autoconf build method in the installation
1406 
documentation. Inspired by a user report of having looked there first rather
1407 
than at Make.htm; an understandible choice based on linux packaging
1408 
conventions. (doc/Install.htm [1.35]: 2002/09/16 21:15:39 giles)
1409 
	- Keep pagedevice and device views of .LockSafetyParams correct even
1410 
after a 'restore' is used to unlock. The dictionary fed to the setpagedevice
1411 
operator is allocated in the same VM space as currentpagedevice to avoid
1412 
invalidaccess problems. Fixed SF #580029 and does not revert to the
1413 
incorrect behaviour of bug #516379. (doc/Language.htm [1.53]: 2002/09/18

without allocating path segments. SourceForge bug "[ 605200 ] pdf_close

1676 
Attached is a updated version of our code release of 4 October, 2002. As
1677 
before, the primary purpose of this release is to modify the manner in which
1678 
overprint information is passed to the overprint compositor device. This
1679 
resolves some difficulties seen when overprinting is used with the command
1680 
list device. This update incorporates the changes checked in by Dan on
1681 
October 4th. Since Dan's changes to gxcldev.h and gxclrast.c were identical
1682 
to ours, we have removed those two files from this release. Jan Modified
1683 
Files lib/gs_init.ps lib/pdf_draw.ps Change "DONTPS" flag to "DOPS", with
1684 
the logically inverted function: only if DOPS is defined will "PS" XObjects
1685 
be rendered. We believe this is the more appropriate default. lib/gs_dps.ps
1686 
lib/gs_img.ps src/gsdparams.c Modified the deviceinfo and image code to work
1687 
around a potentially improperly set ColorValues parameter. src/devs.mak
1688 
Updated dependency list for gdevscf.$(OBJ). src/gdevdflt.c 1. Added
1689 
initialization of the new color_info.opmode field to
1690 
gx_device_fill_in_procs. 2. In get_decode_color, added special case handling
1691 
for canonical 1-bit CMYK devices (e.g.: pkmraw). Previously the decode_color
1692 
method for this devices would default to gx_default_cmyk_decode_color, which
1693 
performed an CMYK ==&gt; RGB ==&gt; CMYK conversion. This conversion would
1694 
defeat overprinting if gray object was placed on top of a colored region.

1697 
src/gsptype2.c src/gsstate.c src/gsstate.h src/gxcmap.c src/gxcspace.h
1698 
src/zcolor.c Modified the overprint code to, when necessary, pass overprint
1699 
mode information when setting the device color. This is necessary to
1700 
properly handle overprint mode when using the command list device. NB: This
1701 
change alters the meaning of the "effective_overprint_mode" field in the
1702 
imager state. src/gxdevcli.h Added the opmode and process_comps fields to
1703 
the gx_device_color_info structure. These are required by the new code that
1704 
passes overprint mode information when the device color is set.
1705 
src/gsdfilt.h Changed the prototype for the push method in the
1706 
gs_device_filter structure to match the actual implementation and usage of
1707 
this method (the third and fourth operands were reversed). src/gsimage.c
1708 
Modified gx_image_cleanup to check if penum-&gt;info field is null before
1709 
calling gx_image_end. This avoids a crash associated that can occur if an
1710 
image has zero height or width, as the image enumeration data structure will
1711 
have been released in such cases before gs_image_cleanup is called.

Add a setup the shift and mask bits in ppm_open. This finishes initializing
1722 
the device as being "linear and separable". This is needed since the various
1723 
pxm devices are using the default color encode routine which needs the

  1. Most of the code changes are required to turn off overprint mode when

1969 
    Modified the cs_install procedure for DeviceN color spaces to
1970 
    support the component name array "[ All ]". The documentation
1971 
    indicates that this is not legal ("PDF Reference", 3rd. ed.,
1972 
    p. 206), but beginning with Acrobat 5, DeviceN color spaces with
1973 
    this component name array are handled in the same manner as
1974 
    Separation color spaces with the component name All. The modified
1975 
    code detects this component array and converts the operand color
1976 
    space to a Separation color space.

1979 
The attached code release fixes a variety of memory handling problems
1980 
discovered by Dan's test with the memory validation enabled.
1981 
 
1982 
  2. Several problems noted with files 119-01.ps (panel 119-07) and
1983 
     119-28.ps (panel 119-31) were caused by a problem with the memory
1984 
     allocator used for the jpeg_compress_data structure used with the
1985 
     DCTEncode (JPEG) filter. This filter is used by the PDFwriter, the
1986 
     JPEG device drive, and as a filter accessible from PostScript.
1987 
     In the first two cases the jpeg_compress_data structure is allocated
1988 
     using the normal, gs_ref_memory_t structure. When used from
1989 
     PostScript, however, this structure is allocated using the
1990 
     gs_memory_default allocator (presumably because the jpeg library
1991 
     code is not set up to deal with save/restore).
1992 
 
1993 
     The gs_memory_default allocator is not a gs_ref_memory_t allocator,
1994 
     so it does not create the hidden obj_header_t structures preceding
1995 
     each allocated region. The garbage collector is dependent on these
1996 
     headers, hence the pointer enumeration routines in structure
1997 
     descriptors must not enumerate any pointers to memory allocated
1998 
     by non-gs_ref_memory_t headers.
1999 
 
2000 
     This creates a difficult problem for the pointer enumeration
2001 
     routine of the stream_DCT_state structure, whose data.compress field
2002 
     points to a jpeg_compress_data structure. This routine would have
2003 
     to determine which allocator was used for this structure before
2004 
     deciding whether or not to "enumerate" the data.compress pointer.
2005 
     In principle it has enough information to do this (the jpeg_memory
2006 
     field of the structure), but this seems like a overly complicated
2007 
     solution. Use of a stable gs_ref_memory_t allocator in place of
2008 
     the gs_memory_default allocator seems like a simpler solution.
2009 
 
2010 
  src/zfdcte.c
2011 
    Modified zDCTE to place the jpeg_compress_data structure into stable
2012 
    memory rather than use the gs_memory_default allocator.

Attached is a updated version of our code release of 4 October, 2002.
2048 
 
2049 
As before, the primary purpose of this release is to modify the manner
2050 
in which overprint information is passed to the overprint compositor
2051 
device.  This resolves some difficulties seen when overprinting is
2052 
used with the command list device.
2053 
 
2054 
This update incorporates the changes checked in by Dan on October 4th.
2055 
Since Dan's changes to gxcldev.h and gxclrast.c were identical to ours,
2056 
we have removed those two files from this release.

2079 
    1. Added initialization of the new color_info.opmode field to
2080 
       gx_device_fill_in_procs.
2081 
    2. In get_decode_color, added special case handling for canonical 1-bit
2082 
       CMYK devices (e.g.: pkmraw). Previously the decode_color method for
2083 
       this devices would default to gx_default_cmyk_decode_color, which
2084 
       performed an CMYK ==&gt; RGB ==&gt; CMYK conversion. This conversion would
2085 
       defeat overprinting if gray object was placed on top of a colored
2086 
       region.
2087 
 
2088 
  src/zcolor.c
2089 
    Modified the overprint code to, when necessary, pass overprint mode
2090 
    information when setting the device color. This is necessary to properly
2091 
    handle overprint mode when using the command list device.
2092

2216 
 
2217 
The attached code release addresses a number of issues:
2218 
 
2219 
  1. Most of the code changes are required to turn off overprint mode when
2220 
     processing images, smooth shading fills (shfill operator), or
2221 
     when using PatternType 2 (smooth shading) patterns.
2222 
 
2223 
  2. A few other changes were required to correct improper updating of the
2224 
     overprint compositor information.
2225 
 
2226 
  3. The code has been modified to avoid the crash that was observed for
2227 
     the file 86554321.pdf on MSWindows XP systems.
2228 
 
2229 
  4. The command list playback code has been modified to handle filling of
2230 
     thin lines in a manner consistent with the noband case. This allows
2231 
     files such as mspro.pdf to be rendered consistently in the banded and
2232 
     noband case.
2233 
 
2234 
                                                                Jan
2235 
 
2236 
 
2237 
Modified Files:
2238 
 
2239 
  src/gscolor2.c
2240 
    1. Modified gs_setcolorspace to call gs_do_set_overprint rather than
2241 
       invoking the color space's set_overprint routine directly. This
2242 
       allows pattern color spaces to be handled (somewhat more) correctly.
2243 
    2. Modified gs_setcolor to update overprint information. This is
2244 
       necessary for pattern color spaces, where the color space to be used
2245 
       for overprint purposes may be part of the color.
2246 
 
2247 
  src/gscspace.c
2248 
    Modified gx_set_overprint_DeviceCMYK to use the effective_overprint_mode
2249 
    parameter in the image state (rather than the overprint_mode parameter
2250 
    itself). This is part of the change necessary to allow overprint mode to
2251 
    be turned off when a PatternType2 pattern is used as the current color.
2252 
 
2253 
  src/gsdevice.c
2254 
    Modified gs_set_device_no_init to call gs_do_set_overprint rather than
2255 
    invoking the color space's set_overprint routine directly.
2256 
 
2257 
  src/gsdps1.c
2258 
    Modified rectfill to use the effective_overprint_mode parameter in the
2259 
    imager state (rather than the overprint_mode parameter).
2260 
 
2261 
  src/gsovrc.c
2262 
    1. Fixed a bug in overprint_draw_thin_line: the third and fourth
2263 
       operands in the call to gx_default_draw_thin_line (the y coordinate
2264 
       of the first point and the x-coordinate of the second) were
2265 
       in reverse order. This caused random lines to appear on various
2266 
       overprint mode tests (e.g.: BEST99-00-Path.fh7.pdf,
2267 
       Testform.v1.0.2.pdf).
2268 
    2. Fixed typo in comment.
2269 
    3. Modified the fill_in_procs procedure to initialize the device color
2270 
       model information for the temporary device used in this routine.
2271 
       Though the color model information does not affect the output of
2272 
       the routine, reasonable values must be provided to avoid problems
2273 
       when gx_device_forward_fill_in_procs calls gx_device_fill_in_procs.
2274 
       This would cause certain systems to crash with files that involved
2275 
       overprint/overprint mode (e.g.: 86554321.pdf on MSWinXP/MSVC systems).
2276 
    4. Modified several checks that treated the separable_and_linear flag
2277 
       in the device color model information as a boolean to handle this
2278 
       parameter as an enumeration instead (since it is an enumeration).
2279 
 
2280 
  src/gsptype1.c
2281 
    Added gs_pattern1_set_color, the set_color method appropriate for
2282 
    PatternType 1 patterns. This method performs overprint updating at
2283 
    setcolor time, a requirement for patterns as the "colorspace" to be
2284 
    used for overprint purposes is determined (in part) by the current
2285 
    "color" (pattern).
2286 
 
2287 
  src/gsptype2.c
2288 
    Added gs_pattern2_set_color, the set_color method appropriate for
2289 
    PatternType 2 patterns.
2290 
 
2291 
  src/gsstate.c
2292 
    1. Changed the criterion used in gs_grestore_only to determine if the
2293 
       overprint compositor must be updated. Restoring the graphic state
2294 
       may change the current color, which in the case of patterns may
2295 
       change the "colorspace" to be used for overprint purposes. The code
2296 
       now properly handles this possibility.
2297 
    2. Added the gs_do_set_overprint routine, and modified various other
2298 
       routines that directly call the current color space's
2299 
       set_overprint method to call this procedure instead. The procedure
2300 
       implements the special handling required for pattern color spaces,
2301 
       where the current color may need to be considered when determining
2302 
       which color model components must be retained.
2303 
    3. Added code to initialize the effective_overprint_mode parameter in
2304 
       the imager state, and provided two external routines to manipulate
2305 
       this parameter. The first routine, gs_disable_effective_overprint_mode,
2306 
       sets the effective_overprint_mode parameter to false, irrespective
2307 
       of the setting of the overprint_mode parameter. The second,
2308 
       gs_reset_effective_overprint_mode, sets the effective_overprint_mode
2309 
       parameter to have the same value as the overprint_mode parameter.
2310 
       The effective_overprint_mode parameter is used to turn off
2311 
       overprint_mode when a PatternType 2 pattern is being used.
2312 
 
2313 
  src/gsstate.h
2314 
    Added prototypes for gs_do_set_overprint,
2315 
    gs_disable_effective_overprint_mode, and
2316 
    gs_reset_effective_overprint_mode.
2317 
 
2318 
  src/gxccache.c
2319 
    Modified gx_image_cached_char to invoke gx_set_dev_color before calling
2320 
    (non-standard) device fill_mask methods. This handles several
2321 
    situations in which a device color is not set when a cached character
2322 
    is to be imaged, in particular for the command list device.
2323 
 
2324 
  src/gxclpath.c
2325 
    Added a comment to indicate that, though the overprint and
2326 
    overprint_mode parameters are passed through the command list, they
2327 
    usually have no effect, as overprint is controlled by the compositor
2328 
    information that is (also) passed through the command list.
2329 
 
2330 
  src/gxclrast.c
2331 
    1. Added a comment to indicate that the overprint and overprint mode
2332 
       parameters passed through the command list usually have no effect.
2333 
    2. Added code to initialize the effective_parameter_mode field in the
2334 
       imager state (though this field is usually in-effective).
2335 
    3. Initialized the fill_zero_width field of the fill_params structure
2336 
       in clist_playback_band to have the same value as in the noband case.
2337 
       This parameter was previously always set to false, which led to
2338 
       dropped lines for some files (e.g.: mspro.pdf).
2339 
 
2340 
  src/gxistate.h
2341 
    Added the effective_overprint_mode parameter.
2342 
 
2343 
  src/gxpcolor.h
2344 
    Added a set_color method to the pattern method vector. This method
2345 
    performs any PatternType-specific actions necessary at setcolor
2346 
    time. For now, this just updates the overprint compositor as required.

2359 
 
2360 
 
2361 
  src/gxccache.c
2362 
    1. Fixed numerous problems with compress_alpha_bits and its invocation in
2363 
       gx_image_cached_char. The former procedure is called only if anti-
2364 
       aliasing (text alpha bits &gt; 1) is called for a color that requires
2365 
       halftoning or for a device, such as pbmraw, that does not support the
2366 
       copy_alpha method. This happens infrequently, and the code was
2367 
       apparently never used.
2368 
    2. Moved the invocation of gs_set_dev_color to an earlier location in
2369 
       gx_image_cached_char, so that the device color will be set before
2370 
       any check is made to see if it is a pure color.
2371 
 
2372 
  src/gxclimag.c
2373 
    1. Added code in clist_fill_mask to return an error if the mask to be
2374 
       filled has depth &gt; 1 and clist_disable_copy_alpha flag is set in the
2375 
       disable_mask field. The latter will be the case if the target device
2376 
       does not support copy alpha. The command list translates fill_mask
2377 
       calls into copy_alpha calls, which drives this requirement. By
2378 
       returning an error, the fall-back mechanism included in
2379 
       gx_image_cached_char (gxccache.c), which is the only client of the
2380 
       fill_mask method, can function properly.
2381 
    2. Also modified clist_fill_mask to check that the drawing color is
2382 
       pure if depth &gt; 1 and use the default fill_mask method if this is
2383 
       not the case. (The copy_alpha call to which the command list code will
2384 
       translate the fill_mask works only for pure colors.) In addition, if
2385 
       the color is pure, the clist_fill_mask routine will now send commands
2386 
       to set color1 as well as transmit the device color; the code in
2387 
       clist_playback_band (gxclrast.c) assumes that all "copy_mono" and
2388 
       "copy_alpha" commands have set color1.
2389 
 
2390 
  src/gxclist.c
2391 
    Added code in clist_init_data to set the clist_disable_copy_alpha bit
2392 
    in the disable_mask field if the target device does not support the
2393 
    copy_alpha method. This must be done in this rather unintuitive location
2394 
    because it is impossible to tell if the target device supports copy_alpha
2395 
    until it has been made into a memory device (via the create_buf_device
2396 
    buffer device method).
2397 
 
2398 
  src/gxclist.h
2399 
    Defined the clist_disable_copy_alpha bit, which is used in the
2400 
    disable_mask field to indicate that the target device does not support
2401 
    the copy_alpha method.
2402 
 
2403 
  src/gxclrast.c
2404 
    Added include of gzht.h, to silence some compiler complaints.
2405 
 
2406 
  src/gxclrect.c
2407 
    Modified clist_copy_alpha to return an error if clist_disable_copy_alpha
2408 
    bit is set in the disable_mask field. This bit indicates that the target
2409 
    device does not support the copy_alpha method, so we might as well
2410 
    return an error now, while there is a chance the client might be able to
2411 
    do something about it.

Modified files:

2432 
  gxcldev.h
2433 
    Added the macros cmd_depth_to_code and cmd_code_to_depth. These allow
2434 
    encoding/decoding of the color model depth parameter (bits/pixel) in
2435 
    such a manner as to support depths up to 120 bits (depths > 15 bits
2436 
    must be a multiple of 8).

The attached code generalizes the sample_load_* and sample_store_* macros
2448 
in gsbitops.h to handle depths up to 64 bits. In addition to providing
2449 
64 bit versions of these macros, we also added the macros sample_load_any,
2450 
sample_load_next_any, and sample_store_next_any. These macros are intended
2451 
to be used in situations in which any supported depth may be used. All of
2452 
the invocations of the sample_load32, sample_load_next32, etc. macros have
2453 
been changed to invoke the *_any version of these macros instead. In
2454 
addition, a few minor changes have been made to silence compiler warning
2455 
messages.
2456 
 
2457 
Modified files:
2458

2460 
    Changed invocations of the sample_{load|store}_next32 macro to be
2461 
    invocations of sample_{load|store}_next_any instead. Also made various
2462 
    changes to allow the code to be compiled with the DeviceN system (the

    value being read/written be of type gx_color_index rather than
2480 
    type bits32.
2481 
 
2482 
  src/gsbitops.h
2483 
    Added 64-bit versions of the sample_load* and sample_store* macros.
2484 
    Also added *_any versions of these macros, to be used in situations
2485 
    where any supported color depth may be encountered.

2488

src/gsht.c 1. Fixed a memory handling problem in gx_imager_dev_ht_install,
2495 
which could result in objects being freed multiple times. 2. Removed a
2496 
temporary hack in gx_imager_dev_ht_install that ensured that the halftone
2497 
cache always had at least one tile per level. This hack is no longer
2498 
necessary, as binary halftone device colors are now handled correctly.

Modified Files: src/gsht.c Modified the invocation of

gx_device_halftone_release in gx_ht_install to use the memory allocator
2515 
pointer stored in the device halftone, rather than the one stored in the
2516 
graphic state. src/gsimage.c Removed what appears to have been an errant
2517 
optimization in gx_image_cleanup. This procedure will now always invoke
2518 
gx_image_end, even if the image was not rendered (penum-&gt;dev == 0).

2520 
 
2521 
 
2522 
The attached code release fixes a variety of memory handling problems
2523 
discovered by Dan's test with the memory validation enabled.
2524 
 
2525 
  1. Most of the problems with the FTS were accounted for by a relatively
2526 
     harmless dangling pointer problem for paths. In order to support the
2527 
     charpath operator, paths are normally constructed in stable memory
2528 
     (not subject to save/restore). However, clipping paths were
2529 
     constructed in normal memory. If the clippath operator was used to
2530 
     make the clipping path the current path, the top-level
2531 
     gx_path_segments would be in stable memory, while the rest of the
2532 
     path would be in normal memory. A restore operation could then
2533 
     leave dangling pointers.
2534 
 
2535 
     This is not normally a problem, because the grestore operation
2536 
     associated with the restore would clear the gx_path_segments
2537 
     structure. This only works on the graphic state stack, however;
2538 
     graphic state objects stored in VM would not be reset.
2539 
 
2540 
     This is harmful only in a very obscure case when the charpath operator
2541 
     is used on a user-defined font whose BuildGlyph procedure contains
2542 
     internal save/restore operators and which builds part of its
2543 
     output with the clippath operator. As far as we know, this has
2544 
     never occurred in practice.
2545 
 
2546 
  2. [...zDCTE stable memory...]
2547 
 
2548 
  3. If an overprint compositor was used with a banding device, the code
2549 
     in clist_playback_band was not cleaning up this compositor before
2550 
     exiting. This caused difficulty with the p2b-100.pdf file. This
2551 
     code has been modified to close the target device if this device
2552 
     does not match the original target device with which the routine
2553 
     was invoked.
2554 
 
2555 
  4. For historical reasons, the link between a halftone order and its
2556 
     tile cache is a bit peculiar. The order includes a pointer to the
2557 
     tile cache, and the tile cache keeps a copy of the order, which
2558 
     points to the same levels/bit data structure of the original order.
2559 
     Because of these two-way points, the order and its tile cache must
2560 
     use the same memory allocator to avoid dangling pointer problems.
2561 
     The code patch modifies gx_imager_dev_ht_install (gsht.c) to
2562 
     preserve this invariant. The change fixes another problem noted for
2563 
     p2b-100.pdf.
2564 
 
2565 
With these changes, we are able to run both the PS3 FTS and the full set
2566 
of pdf regression files using the '-Z@$?' switch with no reported problems.
2567

Modified files:
2572 
 
2573 
  src/gspaint.c
2574 
  src/gspath.c
2575 
    In gs_strokepath and gs_clippath, cause the newly constructed path to
2576 
    use the memory allocator of the current path, rather than the memory
2577 
    of the current graphic state. This is no longer strictly necessary
2578 
    due to other changes that place path substructure completely in
2579 
    stable memory (see gxpath.c below).
2580 
 
2581 
  src/gxpath.c
2582 
    Modify path_allocs_segments, rc_free_path_segments_local,
2583 
    gx_path_add_lines_notes, and the path_alloc_segment macro to place
2584 
    the entire path substructure (from the gx_path_segments structure
2585 
    down) in stable memory. This is necessary to avoid dangling
2586 
    pointers, as a list of path segments may be attached to another path,
2587 
    parts of which were constructed with a different allocator.
2588 
 
2589 
  src/gsht1.c
2590 
    Removed obsolete code.
2591 
 
2592 
  src/gxclrast.c
2593 
    In clist_playback_band, close and discard the target device on
2594 
    completion of a band if it is not the same as the target device on
2595 
    entry.  This is necessary to remove an overprint compositor that
2596 
    may have been created in the course of the band.
2597 
 
2598 
  src/gsht.c
2599 
    In gx_imager_dev_ht_install, copy any halftone orders that were not
2600 
    allocated using the same allocator as used by the graphic state. This
2601 
    must be done to avoid dangling forward/back pointer between halftone
2602 
    orders and the associated tile caches.

Move the callback routine, which is used to translate a gs_separation_name

Attached is a updated version of our code release of 4 October, 2002.
2637 
 
2638 
As before, the primary purpose of this release is to modify the manner
2639 
in which overprint information is passed to the overprint compositor
2640 
device.  This resolves some difficulties seen when overprinting is
2641 
used with the command list device.
2642 
 
2643 
This update incorporates the changes checked in by Dan on October 4th.
2644 
Since Dan's changes to gxcldev.h and gxclrast.c were identical to ours,
2645 
we have removed those two files from this release.

2654 
    Change "DONTPS" flag to "DOPS", with the logically inverted function:
2655 
    only if DOPS is defined will "PS" XObjects be rendered. We believe this
2656 
    is the more appropriate default.

2662 
    improperly set ColorValues parameter.
2663 
 
2664 
  src/devs.mak
2665 
    Updated dependency list for gdevscf.$(OBJ).
2666 
 
2667 
  src/gdevdflt.c
2668 
    1. Added initialization of the new color_info.opmode field to
2669 
       gx_device_fill_in_procs.
2670 
    2. In get_decode_color, added special case handling for canonical 1-bit
2671 
       CMYK devices (e.g.: pkmraw). Previously the decode_color method for
2672 
       this devices would default to gx_default_cmyk_decode_color, which
2673 
       performed an CMYK ==> RGB ==> CMYK conversion. This conversion would
2674 
       defeat overprinting if gray object was placed on top of a colored
2675 
       region.

2693 
    Modified the overprint code to, when necessary, pass overprint mode
2694 
    information when setting the device color. This is necessary to properly
2695 
    handle overprint mode when using the command list device.
2696 
 
2697 
    NB: This change alters the meaning of the "effective_overprint_mode" field
2698 
        in the imager state.
2699 
 
2700 
  src/gxdevcli.h
2701 
    Added the opmode and process_comps fields to the gx_device_color_info
2702 
    structure. These are required by the new code that passes overprint mode
2703 
    information when the device color is set.
2704 
 
2705 
  src/gsdfilt.h
2706 
    Changed the prototype for the push method in the gs_device_filter
2707 
    structure to match the actual implementation and usage of this method
2708 
    (the third and fourth operands were reversed).
2709 
 
2710 
  src/gsimage.c
2711 
    Modified gx_image_cleanup to check if penum->info field is null before
2712 
    calling gx_image_end. This avoids a crash associated that can occur if
2713 
    an image has zero height or width, as the image enumeration data structure
2714 
    will have been released in such cases before gs_image_cleanup is called.

<h3><a name="7.30_Incompatible_changes"></a>Incompatible changes</h3>
2904 
 
2905 
<p>
2906 
A number of DeviceN changes can cause incompatibility. They are
2907 
summarized below.
2908 
 
2909 
<pre>
2910 
* gx_color_index may now be 32 or 64 bits, determined at compile time.
2911 
 
2912 
* The gx_device_color_info field has been updated to include
2913 
  significantly more information about the encoding from colors in the
2914 
  process color model to gx_color_index colors. New fields include:
2915 
  polarity, gray_index, separable_and_linear, comp_shift, and comp_bits.
2916 
  Devices are strongly encouraged to set these new fields correctly.
2917 
  See gxdevcli.h for more information.
2918 
 
2919 
* Some existing device procedures for color mapping have changed.
2920 
  map_rgb_color now takes a cv[] array rather than separate red, green,
2921 
  and blue scalar color values, and similarly for map_cmyk_color.
2922 
 
2923 
* New device procedures: get_color_mapping_procs, get_color_comp_index,
2924 
  encode_color, decode_color. These device procedures are required for
2925 
  devices defining additional colorant planes, and may be desirable for
2926 
  finer control over color mapping. See gxdevcli.h and gxcmap.c for
2927 
  more information.

after DeviceN merge. (lib.mak [1.91]: 2002/08/22 10:00:48 igor)
3008 
	- Logic to invoke banding was confused. Banding gets used when the
3009 
bandsize is too small for the full page raster. A bandsize of 10000 causes
3010 
banding. (toolbin/tests/gstestgs.py [1.12]: 2002/09/04 23:09:12 ray)
3011 
	- Provide an implementation of popen for Windows, to avoid the

3408 
From ORIMP: Modified files: src/gsht.c: In gx_imager_dev_ht_install, the
3409 
comp_number field in the entries for the newly allocated components_array
3410 
was improperly assigned, due to a typo. Later code checks if the comp_number
3411 
value matches the component index and, if not, uses the default halftone
3412 
order for this component. This would cause a typical 4-color device to
3413 
always use the default halftone component (and leak memory). As part of the
3414 
same fix, some redundant code in gx_imager_dev_ht_install has been removed,
3415 
and the code that updates the "used_default" variable in this procedure has
3416 
been corrected. (gsht.c [1.7]: 2002/08/23 07:43:30 dan)
3417 
 
3418 
Modified files: src/gstext.h src/gstext.c Added the routine
3419 
gs_text_update_dev_color, to update the color used for drawing text if this
3420 
changes during a text operation (e.g.: due to the action of a kshow or cshow
3421 
procedure). src/zchar.c Modified op_show_continue to call
3422 
gs_text_update_dev_color in case a cshow or kshow procedure changed the
3423 
current color (strictly speaking, this is only a problem with kshow).
3424 
(gstext.c [1.10], gstext.h [1.7]: 2002/08/26 22:51:53 dan)
3425 
 
3426 
Modified files:
3427 
 
3428 
  src/gdevdbit.c:
3429 
    Changed gx_default_fill_mask to use the fill_masked routine of the
3430 
    device color. This avoids an instance in which a possibly
3431 
    uninitialized halftone tile is used for drawing. It also makes the
3432 
    code considerably cleaner.
3433 
 
3434 
  src/gscdefs.h
3435 
    Re-installed the definition of extern_gs_find_compositor, which had
3436 
    in-advertently been lost in a recent code merge.
3437 
 
3438 
  src/gsdcolor.h
3439 
    Added the colors.binary.b_level field to the gx_device_color_saved
3440 
    structure. Also added a comment explaining why this structure is
3441 
    used rather than the gx_device_color structure itself.
3442 
 
3443 
  src/gsht.c
3444 
    This file should be identical to the version released on Aug. 22nd.
3445 
    We are releasing again here just to guard against this code being
3446 
    committed without the former change.
3447 
 
3448 
  src/gsht1.c
3449 
    Modified the check for "binaryness" of a device color model in
3450 
    gs_sethalftone_try_wts to handle cases in which not all of the depth
3451 
    bits are used.
3452 
 
3453 
  src/gstext.c,
3454 
  src/gxtext.h
3455 
  src/zchar.c
3456 
    These files are identical to the set released on Aug. 23rd (the fix
3457 
    for color changes in a kshow procedure). We are releasing them again
3458 
    here to make certain the rest of this code is not committed without
3459 
    the former change.
3460 
 
3461 
  src/gxacpath.c
3462 
    Modified gx_cpath_accum_end to set the new bbox_accurate field rather
3463 
    than the bbox_set field. This avoids overloading the bbox_set field
3464 
    in a way that can lead to inconsistent output when the setbbox
3465 
    operator is used with a path.
3466 
 
3467 
  src/gxcht.c
3468 
  src/gxht.c
3469 
  src/gxdcolor.c
3470 
  src/gxdcolor.h
3471 
    Modified the "write" methods for various color spaces so that their
3472 
    return value can indicate that the operand and last transmitted
3473 
    colors are the same. Also fixed various bugs uncovered when the
3474 
    modular device color serialization/de-serialization was first used.
3475 
    The changes to gxdcolor.h involve only comments.
3476 
 
3477 
  src/gxcldev.h
3478 
    1. Added a saved device color (gx_device_color_saved) to the band
3479 
       state structure.
3480 
    2. Removed the (long since unnecessary) type operand from the
3481 
       cmd_put_halftone procedure.
3482 
    3. Commented out some now obsolete command codes.
3483 
 
3484 
  src/gxclimag.c
3485 
    1. Modified clist_fill_mask to work with the new, modular drawing
3486 
       color serialization/de-serialization routines.
3487 
    2. Rewrote cmd_put_halftone as required by the new mechanism for
3488 
       serializing/de-serializing device halftones.
3489 
    3. Modified various invocations of cmd_put_halftone to discard the
3490 
       the type operand.
3491 
 
3492 
    Note: The existing code impose a requirement that image objects that
3493 
          used a device color (e.g.: image masks) would only be passed
3494 
          through the command list if that color is pure. We do not
3495 
          know why this limitation was necessary, and suspect it is no
3496 
          longer necessary, but we have left it in place for now.
3497 
 
3498 
  src/gxclist.c
3499 
    Added gxdcolor.h to the included file list.
3500 
 
3501 
  src/gxclpath.c
3502 
    1. Rewrote cmd_put_drawing_color to use the new mechanism for
3503 
       serialization/de-serialization of device colors.
3504 
    2. Removed the device color type information from the stroke/
3505 
       fill/polyfill commands.
3506 
    3. Modified cmd_put_path so that "moveto closepath" is not
3507 
       passed through the command list as just "moveto".
3508 
 
3509 
  src/gxclpath.h
3510 
    1. Added the cmd_opv_ext_put_ht_seg, to allow device halftones to be
3511 
       split across multiple command buffers. Also added the macro
3512 
       cbuf_ht_seg_max_size, to indicate the largest halftone segment to
3513 
       be put in a single command buffer.
3514 
    2. Commented out some now obsolete command codes.
3515 
  src/gxclrast.c
3516 
    1. Modified the code to read device halftones and device colors to
3517 
       use the new serialization/de-serialization methods for these
3518 
       structures.
3519 
    2. Modified various locations in which partial/temporary device
3520 
       colors are used to use the current color for the band.
3521 
    3. Removed code for the various stroke/fill/polyfill commands that
3522 
       encode device color type as part of the command.
3523 
    4. Added code to save the current color when a pure color must be
3524 
       set to generate a clip region using the fill procedure.
3525 
    5. Modified the clip path reading code to flatten the clip path
3526 
       before passing it to the fill operation. This is necessary to
3527 
       ensure consistent results between the banded and non-banded
3528 
       cases (the non-banded case also flattens a clip path before
3529 
       passing it to the fill operation).
3530 
 
3531 
  src/gxdhtserial.c
3532 
    1. Updated gx_ht_read_tf and gx_ht_read_and_install to properly
3533 
       use the reference count in a transfer function.
3534 
    2. Fixed various other errors discovered when this code was first
3535 
       used.
3536 
 
3537 
  src/gxdhtserial.h
3538 
    Fixed typo.
3539 
 
3540 
  src/gxpath.c
3541 
    Initialize the new bbox_accurate field of the gx_path structure to
3542 
    false in gx_path_init_contents.
3543 
 
3544 
  src/gxpath2.c
3545 
    Modified gx_path_bbox to use the bbox_accurate rather than bbox_set
3546 
    field to determine if the bounding box of a path needs to be
3547 
    explicitly calculated. If bbox_set is true, the bounding box
3548 
    in the bbox field will contain the current path, but may be larger
3549 
    than necessary. Due to a problem in the clip/fill code, the larger
3550 
    bounding box may generate slightly inconsistent results.
3551 
 
3552 
  src/gzpath.h
3553 
    Added the bbox_accurate field to the gx_path_s structure. This field
3554 
    is used by the clip accumulator device, which avoids the need to
3555 
    overload the bbox_set field (which is also used by the setbbox
3556 
    operator).
3557 
 
3558

Another fix of a problem that had been previously fixed and lost due to a
3568 
commit of files from ORIMP. MSVC will not accept { } for a structure
3569

3570 
Igor. (gsht1.c [1.10]: 2002/08/26 23:07:00 dan)
3571 
 
3572 
We have traced the difficulties with multiple-band processing in the code
3573 
we released on Aug. 26 to two problems:
3574 
 
3575 
  1. The halftone phase information is not adjusted for bands that
3576 
     start at locations other than the top of the page.
3577 
 
3578 
  2. The "moveto closepath" style of degenerate path, which our code
3579 
     allows to be passed through the band list, is used in the path
3580 
     encoding code to indicate that a path lies entirely outside the
3581 
     current band (i.e.: all of the path operators between the initial
3582 
     moveto and the final closepath have been skipped because they are
3583 
     outside of the band). This resulted in the code passing isolated
3584 
     "closepath" segments through the command list, which much confused
3585 
     the band list renderer.
3586 
 
3587 
The attached code release fixes both of these problems, and a couple of
3588 
other more minor issues we discovered. With this change, our system has
3589 
identical output for the banded and unbanded case for the pkmraw device
3590 
at 300 dpi, for all but one FTS file (027-09.ps). In that one case, the
3591 
banded and unbanded output are visually identical, so the output difference
3592 
may not be significant. We will look into this situation, and test some
3593 
of the other devices in the next day or so.
3594 
 
3595 
As best we can tell, halftone phase adjustment has never been correctly
3596 
implemented for the command list device. The pre-DeviceN code handles
3597 
binary halftone colors properly, but does not set the phase for general
3598 
colored halftones. General colored halftones are much more common in the
3599 
DeviceN code, which probably is the reason Dan first noticed the problem
3600 
with FTS file 245-07.ps (and others) with the DeviceN code.
3601 
 
3602

3604 
Modified Files:
3605 
 
3606 
  src/gsht.c
3607 
    Modified the code that calculates the lcm_height field of a device
3608 
    halftone in gx_imager_dev_ht_install to use the full_height rather
3609 
    than the height of a halftone order. This typo was introduced sometime
3610 
    during the DeviceN development; the pre-DeviceN code was correct.
3611 
 
3612 
  src/gsptype1.c
3613 
  src/gsptype2.c
3614 
  src/gxwts.c
3615 
    Added the "get_phase" method to various gx_device_color_type_t
3616 
    instances.
3617 
  src/gxcht.c
3618 
  src/gxht.c
3619 
    Added the "get_phase" method to a pair of gx_device_color_type_t
3620 
    instances. Also modified the "write" and "read" methods of these
3621 
    structures to ignore halftone phase information. This information
3622 
    must be passed to and be directly handled by the command list
3623 
    writer code, so that the command list renderer code may correct it
3624 
    for the band starting coordinates.
3625 
 
3626 
  src/gxclpath.c
3627 
    1. Modified cmd_put_drawing_color to directly handle halftone phase
3628 
       information, using the new "get_phase" method of device colors.
3629 
       The passing of this information must be perfomed at the command
3630 
       list level, so that the command list renderer can correct the
3631 
       phase for the starting point of the band.
3632 
    2. Also in cmd_put_drawing_color, "unset" the saved color information
3633 
       if the halftone id does not match the most recently set halftone,
3634 
       rather than setting the saved color pointer to 0.
3635 
    3. In cmd_put_path, when processing a segment containing a
3636 
       moveto followed by a closepath, check if the moveto was to a point
3637 
       outside of the current band, and discard the closepath if this
3638 
       is the case. This is necessary to avoid inserting isolated
3639 
       closepath segments into the command list.
3640 
 
3641 
  src/gxclrast.c
3642 
    Added code to initialize the dev_color variable to clist_playback_band
3643 
    to "no color".
3644 
 
3645 
  src/gxdcolor.c
3646 
  src/gxdcolor.h
3647 
    Added the "get_phase" method to the gx_device_color_type_t structure,
3648 
    and installed this method in various instances of the structure. Also
3649 
    provided the two canonical implementations of this method.

The two files were missed in earlier commits. Missing from the 8-28-02
3655 
commit form ORIMP. src/gxdcolor.c Added the "get_phase" method to the
3656 
gx_device_color_type_t structure, and installed this method in various
3657 
instances of the structure. Also provided the two canonical implementations
3658 
of this method. Missing from the 8-26-02 commit from ORIMP.
3659 
src/gxdhtserial.c 1. Updated gx_ht_read_tf and gx_ht_read_and_install to
3660 
properly use the reference count in a transfer function. 2. Fixed various
3661 
other errors discovered when this code was first used. (gxdcolor.h [1.9],
3662 
gxdhtserial.c [1.2]: 2002/08/29 00:11:30 dan)
3663 
 
3664 
The attached code fixes a minor problem introduced in our release
3665 
of August 26th. That release changed the behavior of the gx_path_bbox
3666 
procedure (gxpath2.c) so as to make the banding and non-banding cases
3667 
consistent. In the process we inadvertently also changed the behavior
3668 
of the pathbbox operator. This fix restores the proper behavior of
3669 
that operator.
3670 
 
3671 
Also included is a modified version of gsht.c for interim use. This is
3672 
not intended for final release. The gx_imager_dev_ht_install routine
3673 
is modified in this code to ensure that the halftone caches are also
3674 
made large enough to provide (at least) one tile per level. Doing so
3675 
avoids the cache overwrite bug that Dan has described, which avoids
3676 
many spurious differences in the regression test. Once Dan's fix for
3677 
the handling of the halftone tile in binary halftone colors is
3678 
installed, this version of gsht.c may be discarded.
3679 
 
3680 
Modified files:
3681 
 src/gspath1.c
3682 
    Modified gs_upathbbox to call gx_path_bbox_set rather than
3683 
    gx_path_bbox. The former will return the bounding box set via the
3684 
    setbbox operator, if that operator has been used for the current
3685 
    path; otherwise it will return the actual path bounding box. The
3686 
    latter will always return the actual path bounding box.
3687 
 
3688 
  src/gxpath.h
3689 
  src/gxpath2.c
3690 
    Added the gx_path_bbox_set procedure, which will return the
3691 
    bounding box set by the setbbox operator if that operator has been
3692 
    used for the current path.
3693 
 
3694 
Temporary Files:
3695 
 
3696 
  src/gsht.c
3697 
    Modified the gx_imager_dev_ht_install procedure to always allocate
3698 
    caches large enough to provide (at least) one tile per level. This
3699 
    is a temporary hack to avoid a bug with the handling of tiles for
3700 
    binary halftone colors. It is not intended for the final release.

This is a repeat of an earlier commit that was backed out. Its back. Split
3705 
the binary half tone cache initialization into two pieces. The halftone
3706 
cache is now initialized just prior to being used in the various halftone
3707 
render routines. This was done to prevent a problem with cache conflicts. If
3708 
the half tone cache is not large enough for a separate tile for each level
3709 
then there could be a problem if two different device colors used the same
3710 
cache entry but with different level values. (gxht.c [1.11],

A line was left out of the previous commit. This is part of the splitting of
3714 
the load the binary halftone cache until it is ready to be used.

Modified File: src/gxdevndi.c Modified gx_render_device_DeviceN to always
3718 
perform the conversion from color component intensity values to halftone
3719 
levels in an additive sense, if the gray_colorspace operand is true. This is
3720 
necessary for compatibility with the pre-DeviceN code. (gxdevndi.c [1.2]:

3727 
Changes required for compilation on HPUX and Tru64. Add missing header in
3728 
lib.mak after gxdcolor.h added to gscolor3.c. Change dci_std_color_bits
3729 
macro to prevent a divide by zero, caused by the compiler not using shortcut
3730 
evaluation in an initializer. (gxdevcli.h [1.12]: 2002/09/04 21:44:14

Adds support for the GX_COLOR_INDEX_TYPE define to the autoconf build. The
3744 
script tries a variety of likely candidates for a 64-bit type and passes the
3745 
first one found through the GCFLAGS makefile variable. If no such type is

3807 
 
3808 
        Files Added:
3809 
 
3810 
          gsserial.c        These two files provide a extended and public version
3811 
          gsserial.h        of the little-endian integer encoding used by the
3812 
                            command list. Since serialization can occur
3813 
                            outside of the command list, it is reasonable to have
3814 
                            this facility become a general utility. (For now,
3815 
                            at least, the command-list specific version of this
3816 
                            encoding remains as well.)
3817 
 
3818 
                            gsserial.c includes a unit-test.
3819 
 
3820 
 
3821 
          gxdhtserial.c     Code to serialize device halftones. These are serialized
3822 
          gxdhtserial.h     as a unit, rather than using separate commands for
3823 
                            separate pieces.
3824 
 
3825 
 
3826 
        Files Modified:
3827 
 
3828 
          gsdcolor.h        Removed the no longer used screens field from the wts
3829 
                            field of the colors union of the gx_device_color
3830 
                            structure.
3831 
 
3832 
                            Added the gx_device_color_saved structure, which may be
3833 
                            used by the command list device to retain information
3834 
                            about the last device color placed in a band. Using this
3835 
                            information can reduce the size of the newly encoded
3836 
                            color.
3837 
 
3838 
          gxdcolor.h        Added methods to the gx_device_color_type_t method
3839 
                            vector to support serialization of device colors. The
3840 
                            new methods are:
3841 
 
3842 
                              save_dc
3843 
                                Create a "saved" version of the device color. The
3844 
                                saved version contains information about the
3845 
                                device color, but does not include any pointers.
3846 
                                It can be used to reduce the amount of information
3847 
                                encoded with a device color.
3848 
 
3849 
                              get_dev_halftone
3850 
                                Return the device halftone used by a device color
3851 
                                (or a null pointer if no device halftone is used).
3852 
 
3853 
                              write
3854 
                                Serialize the device color.
3855 
 
3856 
                              read
3857 
                                Reconstruct the device color from its serial
3858 
                                representation.
3859 
 
3860 
                            Also added prototypes for two utilities to be used
3861 
                            when serializing device colors: gx_dc_write_color
3862 
                            and gx_dc_read_color. These work on color indices.
3863 
 
3864 
          gxclpath.h        Added the codes for cmd_opv_ext_put_halftone and
3865 
                            cmd_opv_ext_put_drawing_color.
3866 
 
3867 
          gxpcolor.h        Added prototypes for gx_dc_pattern_save_dc,
3868 
                            gx_pattern_dc_write, and gx_dc_pattern_read. Since
3869 
                            patterns cannot be passed through the command list,
3870 
                            all of these just return errors.
3871 
 
3872 
          gsptype1.c        Added stubs for the new device color methods. The
3873 
          gsptype2.c        get_dev_halftone method is supported to the extent
3874 
                            possible; it cannot be supported for color
3875 
                            PatternType 1 patterns as their PaintProc procedures
3876 
                            may use multiple patterns.
3877 
 
3878 
          gxcht.c           Added support for the new device color methods for
3879 
                            general (colored halftone ) device colors, including
3880 
                            full serialization support.
3881 
 
3882 
          gxht.c            Added support for the new device color methods for
3883 
                            binary halftone device colors, including full
3884 
                            serialization support.
3885 
 
3886 
          gxdcolor.c        Added support for the new device color methods for
3887 
                            the "no color", transparent, and pure device colors,
3888 
                            including serialization support. Also added the two
3889 
                            utility routines gx_dc_write_color and
3890 
                            gx_dc_read_color, which work on color indices.
3891 
 
3892 
          gxwts.c           Added stubs to support the new device color methods.
3893 
                            Also corrected a few minor compiler complaints.
3894 
 
3895 
          lib.mak           Added targets for gsserial.$(OBJ) and
3896 
                            gxdhtserial.$(OBJ). Also updated some dependency
3897 
                            lists.
3898 
 
3899 
        * zcolor.c [1.8] (+1 -2):
3900 
        Modified Files: (jan)
3901 
 
3902 
          lib/gs_cspace.ps
3903 
            Added _setcolorspace_nosub, a variation of the setcolorspace operation that
3904 
            avoids color space substitution. This is required for ICCBased color spaces,
3905 
            as they may be used to substitute for a device-specific color space, but
3906 
            use that same device-specific color space as an alternative space. If the
3907 
            alternative space was used (or even if it wasn't, in the prior code), an
3908 
            infinite loop would result (the eventual error is execstackoverflow).
3909 
 
3910 
          lib/gs_icc.ps
3911 
            Modified the cs_install routine for ICCBased color spaces to use the new
3912 
            _setcolorspace_nosub procedure.
3913 
 
3914 
          lib/pdf_draw.ps
3915 
            Removed the color substitution scheme used by resolvecolorspace. This has
3916 
            been superseded by the PostScript-based scheme.
3917 
 
3918 
          lib/pdf_main.ps
3919 
            Implemented color space substitution using PostScript's method. This works
3920 
            for all color spaces and, with the above noted modifications to
3921 
            gs_cspace.ps and gs_icc.ps, avoids infinite-loop problems. The
3922 
            earlier code did not implement color space substitution for
3923 
            DeviceCMYK (the code was just missing) and in rare cases could
3924 
            suffer from infinite loops.
3925 
 
3926 
          src/zcolor.c
3927 
            Correct a typo: the .setdevcspace operator was included twice in the
3928 
            zcolor_op_defs array.

3960 
        This is the first part of the code we are providing to allow device
3961 
        colors to be passed through the command list in a modular manner. The
3962 
        rest of the code should be released within a couple of days. We are
3963 
        providing this code first because we need to fix these leaks in order
3964 
        for the rest of the code to function correctly, but these fixes are
3965 
        otherwise independent of that code.
3966 
 
3967 
          src/gsht.c:
3968 
 
3969 
            a. Added a (moderately hack-ish) mechanism to allow halftone
3970 
               components to share well-tempered screens. This mechanism uses the
3971 
               width field of the halftone component, which is nominally not used
3972 
               for well-tempered screens, to indicate which component "owns" the
3973 
               screen and can release it.
3974 
 
3975 
            b. Modified gx_ht_alloc_ht_order and gx_ht_copy_ht_order to handle well-
3976 
               tempered screens, which do not have levels or bid_data arrays.
3977 
 
3978 
            c. Created gx_ht_move_ht_order, an analog to gx_ht_copy_ht_order, that
3979 
               assumes ownership of the structure's reference by a source halftone
3980 
               order rather than copying them.
3981 
 
3982 
            d. Modified gx_ht_order_release to handle well-tempered screen
3983 
               component orders, and to decrement the transfer function
3984 
               referenced by a halftone order (as opposed to blindly releasing
3985 
               it).
3986 
 
3987 
            e. Completely re-wrote gx_imager_dev_ht_install, to fix various memory
3988 
               leaks and better handle well-tempered screens. See the comments
3989 
               in the procedure for additional information.
3990 
 
3991 
            f. Modified gx_ht_install to take ownership of all structures referenced
3992 
               by the operand device halftone, if it returns successfully. This
3993 
               matches the behavior of the pre-DeviceN code and is required by
3994 
               various clients to avoid memory leaks. Any referenced structures
3995 
               that are not required by the device halftone in the imager state
3996 
               will be released (again, only on successful completion).
3997 
 
3998 
            g. Modified gx_imager_set_effective_xfer to ignore the "default"
3999 
               order in a device halftone. This order is not used for device
4000 
               halftones installed in the imager state, and
4001 
               gx_imager_set_effective_xfer should only be called for device
4002 
               halftones installed in the imager state.
4003 
 
4004 
          src/gsht1.c:
4005 
            a. Modified gs_sethalftone_allocated to release any unused parts
4006 
               of the device halftone in the event that gx_ht_install returns
4007 
               with an error code.
4008 
 
4009 
            b. Modified gs_sethalftone_prepare to not allocate a cache for
4010 
               (traditional) halftone orders.
4011 
 
4012 
            c. Modified process_transfer to set a reference count of 1 in the
4013 
               transfer functions. This is appropriate, as the routine
4014 
               sets a reference to these structures (in the halftone component
4015 
               order).
4016 
 
4017 
            d. Simplified the check for bi-level device in gs_sethalftone_try_wts.
4018 
 
4019 
            e. Used gs_alloc_struct_array in place of malloc for allocating the
4020 
               component order array in gs_sethalftone_try_wts.
4021 
 
4022 
            f. Set the num_bits and num_levels values in well-tempered screening
4023 
               halftone orders to 0. This setting is required to allow them to
4024 
               be correctly handled by gx_ht_copy_ht_order.
4025 
 
4026 
            g. Added processing of halftones to gx_sethalftone_try_wts.
4027 
 
4028 
 
4029 
          src/gshtscr.c:
4030 
            Modified gs_screen_install to discard any structures referenced by
4031 
            a device halftone if gx_ht_install returns an error code.
4032 
 
4033 
          src/gshtx.c
4034 
            Modified gs_ht_install to discard any structures referenced by
4035 
            a device halftone if gx_ht_install returns an error code.
4036 
 
4037 
          src/gswts.c
4038 
            Added the procedures gs_wts_free_enum and gs_wts_free_screen, to
4039 
            free gs_wts_screen_enum_t and wts_screen_t structures.
4040 
 
4041 
          src/gswts.h
4042 
            Added prototypes for the procedures gs_wts_free_enum and
4043 
            gs_wts_free_screen. These are used by the device halftone
4044 
            code to free gs_wts_screen_enum_t and wts_screen_t structures.
4045 
 
4046 
          src/gxclrast.c
4047 
            Added code in read_set_ht_data to discard just the allocated
4048 
            halftone components array, but not any of the structures
4049 
            it references, after gx_imager_dev_ht_install returns. This is
4050 
            necessary as gx_imager_dev_ht_install will always copy this
4051 
            structure, and cannot release the original.
4052 
 
4053 
            NB: This is an interim change. The mechanism by which halftones
4054 
                are passed through the command list will change shortly.
4055 
 
4056 
          src/gzht.h
4057 
            Modified the prototypes for gx_imager_dev_ht_install and
4058 
            gx_ht_install to remove the const qualifier for the device
4059 
            halftone operand.

        The data section of the gray transfer component (from the setcolortransfer

4094 
        This resulted in gray transfer functions not being transfered properly
4095 
        through the clist.  The fix involves simply removing the 'default_comp'
4096 
        and using the gray component for the default and for the settransfer

        This is the fix for Orimp's image.ps test file.  The image processing
4116 
        routine were special casing 1, 3, and 4 components cases and assuming
4117 
        that there were Gray, RGB, and CMYK.  This did not work for DeviceN
4118 
        colorspaces.  The fix involves using the colorspace remap_color
4119 
        routine instead of going directly to the cmap_procs.  This should be
4120 
        slightly slower (but will work in all cases).

        (Jan) Implements the overprint and overprint mode features for the
4136 
        PostScript and PDF writer devices. These devices have supported the
4137 
        overprint feature for some time. The modifications allow them to
4138 
        intercept and discard the create_compositor invocation for the
4139 
        overprint compositor, as they don't need the compositor and already
4140 
        access overprint information from the imager state.
4141 
 
4142 
        Note: This set of changes is quite simple, but we have no easy way to
4143 
              test the result. Hence, while we believe it very unlikely the
4144 
              changes will cause discrepancies, we have not actually tested
4145 
              them (other than to verify compilation).
4146 
 
4147 
        Modified files:
4148 
 
4149 
          src/devs.mak
4150 
            Updated dependency list for gdevpsdu.$(OBJ).
4151 
 
4152 
          src/gdevpdf.c
4153 
            Added the methods psdf_get_bits, psdf_get_bits_rectangle, and
4154 
            psdf_create_compositor to the method vector initialization of the
4155 
            gs_pdfwrite_device.
4156 
 
4157 
          src/gdevps.c
4158 
            Added the methods psdf_get_bits, psdf_get_bits_rectangle, and
4159 
            psdf_create_compositor to the method vector initialization of the
4160 
            gs_pswrite_device and gs_epswrite_device.
4161 
 
4162 
          src/gdevpsdf.h
4163 
            Added prototypes for the psdf_get_bits, psdf_get_bits_rectangle,
4164 
            and psdf_create_compositor procedures.
4165 
 
4166 
          src/gdevpsdu.c
4167 
            Added the psdf_get_bits, psdf_get_bits_rectangle, and
4168 
            psdf_create_compositor procedures. The first of these just returns
4169 
            an unregistered error. The prior code also generated an error if
4170 
            these methods were called, but via a much more obscure and round-
4171 
            about route. The psdf_create_compositor procedure recognizes and
4172 
            discards invocations of the create_compositor method for the overprint
4173 
            compositor. The PostScript and PDF writers do not need this compositor
4174 
            to support overprint, and would fail if it were present as it
4175 
            requires support for the get_bits/get_bits_rectangle methods.

        Patch from Russel Lang  (gsview@ghostgum.com.au)
4190 
 
4191 
        Anti-aliasing for CMYK devices did not work because
4192 
        gx_default_copy_alpha converted the new and existing pixel
4193 
        values to RGB, merged them then remapped the result. This
4194 
        patch uses decode_color on the two pixels, merges the pixel
4195 
        color values individually, then uses encode_color on the
4196 
        result.
4197 
 
4198 
        To avoid flashes of incorrect colour begin displayed when
4199 
        the display device size is changed, the display device
4200 
        erases the page to white immediately after bitmap
4201 
        allocation. Actually, it was erasing the colour to
4202 
        RGB(1.0,1.0.1.0) by calling map_rgb_color, which actually
4203 
        calls encode_color which is expecting CMYK as input.  This
4204 
        resulted in a black background. This patch changes the code
4205 
        to use encode_color with appropriate values for DeviceGray,
4206 
        DeviceRGB or DeviceCMYK.
4207 
 
4208 
        The display device did not work with CMYK anti-aliasing
4209 
        because the decode_color procedure was decoding to RGB, not
4210 
        CMYK.  This patch adds new cmyk_[18]bit_map_color_cmyk
4211 
        functions for decode_color.

        cm_color_map_procs, it also deleted the setup of cmap_procs.
4227 
        This commit corrects that.

            Fixed a problem in x_copy_image. If the image passed to this routine
4243 
            contains more than one pixel, the colors_and and colors_or fields were
4244 
            not updated. Because these fields are only used for optimization, and
4245 
            properly updating them in this situation is potentially expensive,
4246 
            they are now just set to safe values (colors_and = 0;
4247 
            colors_or = (x_pixel)(-1)).

4289 
        The following should be prominently posted in full view of all
4290 
        software engineers:
4291 
 
4292 
          ***Do not use caches to hold unreplaceable data***
4293 
 
4294 
        Failure to follow that rule of good programming is the heart of the
4295 
        problem with FTS panel 245-04 (file 245-01.ps).
4296 
 
4297 
        The immediate cause of the problem is the optimization put in the
4298 
        setcolorspace code to avoid repeatedly setting the same color space.
4299 
        The steps that lead to the error are the following:
4300 
 
4301 
          1. The job sets a CIEBasedABC color space as the current color
4302 
             space. The white and black point information from the color
4303 
             space dictionary is combined with the white and black point
4304 
             information in the color rendering dictionary to sample the
4305 
             TransformPQR procedures in that dictionary. The resulting
4306 
             data is placed in the joint CIE cache. All of this activity
4307 
             ends with an execution of the internal operator cie_tpqr_finish
4308 
             (zcrd.c). This operator has two side-effects:
4309 
 
4310 
                 The TransformPQR data structure in the cie_render structure
4311 
                 of the current state is set to TransformPQR_from_cache, which
4312 
                 indicates that the PQR phase of the CIE color mapping (the
4313 
                 white point point adjustment) is to be done via the joint CIE
4314 
                 cache.
4315 
 
4316 
                 The gs_cie_cs_complete procedure is invoked with the "init"
4317 
                 argument set to false, indicating that no further
4318 
                 initialization is required for the joint CIE caches. This
4319 
                 causes the status flag in those caches to be set to
4320 
                 CIE_JC_STATUS_INITED, indicating that the caches are ready
4321 
                 to use.
4322 
 
4323 
          2. The job calls gsave. Since the joint CIE caches can be shared by
4324 
             multiple graphic states, the cache reference count is incremented.
4325 
 
4326 
          3. The job sets a pattern color space, whose base color space is the
4327 
             current (CIEBasedABC) color space.
4328 
 
4329 
             The PostScript interpreter in Ghostscript uses the convention that
4330 
             a base or alternative color space will always be set as the current
4331 
             color space immediately before the enclosing color space is set.
4332 
             The cs_install procedure for the pattern color space
4333 
             (lib/gs_patrn.ps) invokes setcolorspace on the base space. Because
4334 
             this is already the current color space, nothing happens.
4335 
 
4336 
          4. Immediately afterwards, the cs_install procedure invokes the
4337 
             .setpatternspace operator on the enclosing pattern color space.
4338 
             Through a couple of layers, this will invoke the "install_cspace"
4339 
             method for pattern color spaces, the gx_install_Pattern
4340 
             (gspcolor.c). This will in turn invoke the "install_cspace" method
4341 
             for the base color space, in this case gx_install_CIE.
4342 
 
4343 
          5. Through a few additional layers, gx_install_CIE will also call
4344 
             gs_cie_cs_complete (see (1) above), but this time the "init"
4345 
             variable will be set to true, indicating that additional
4346 
             initialization is required.
4347 
 
4348 
             gs_cie_cs_complete will invoke gx_currentciecaches, whose purpose
4349 
             is to make sure that new copies of the joint CIE cache is created
4350 
             when necessary. Since the reference count on the existing cache is
4351 
             larger than 1 (see (2) above), a unique copy of the cache is created
4352 
             and is marked as invalid.
4353 
 
4354 
          6. Subsequently, when drawing is attempted in the base color (the
4355 
             pattern has PaintType 2), the code will note that the cache is
4356 
             not yet valid and invoke cie_joint_caches_init (gscie.c). This
4357 
             routine can do nothing, however, because the TransformPQR structure
4358 
             for the cie_render structure in the graphic state is set to
4359 
             TransformPQR_from_cache, indicating that the only data available
4360 
             for the TransformPQR procedure is in the (now invalidated) cache.
4361 
 
4362 
             As a fall-back, the CIE color is mapped to RGB by setting all
4363 
             components to 0, which yields the black output.
4364 
 
4365 
        The proper fix for this problem is re-designing both the CIE color space
4366 
        and the color rendering structures so that they retain enough information
4367 
        to regenerate the joint CIE cache when necessary. Since that is a big
4368 
        change, the attached modifications take the more modest approach of adding
4369 
        a "forcesetcolorspace" operator, which will set a color space even if it
4370 
        is identical to the current color space.
4371 
 
4372 
        Also included in the set of changes is a minor modification to gs_rectfill
4373 
        (gsdps1.c) that suppresses direct access to the device's fill_rectangle
4374 
        procedure if both overprint and overprint mode are true. Since
4375 
        overprintmode must be applied prior to halftoning, the code must be forced
4376 
        through one of the higher-level methods which include the pre-halftoned
4377 
        device color information.
4378 
 
4379 
        Modified files:
4380 
 
4381 
          lib/gs_cspace.ps
4382 
            Added the _setcolorspace procedure, which accepts both a boolean and
4383 
            a color space dictionary. If the boolean is true, the color space
4384 
            will not be set if it is the same as the current color space (via a
4385 
            conservative evaluation).
4386 
 
4387 
            The setcolorspace pseudo-operator now invokes _setcolorspace with the
4388 
            boolean operand set to true. A new operator, forcesetcolorspace,
4389 
            invokes _setcolorspace with boolean set to false.
4390 
 
4391 
          lib/gs_devn.ps
4392 
          lib/gs_icc.ps
4393 
          lib/gs_indxd.ps
4394 
          lib/gs_patrn.ps
4395 
          lib/gs_sepr.ps
4396 
            Replaced setcolorspace with forcesetcolorspace when setting a base or
4397 
            alternative color space. This is necessary due to some problems in the
4398 
            handling of the the joint CIE cache in the graphic library.
4399 
 
4400 
          src/gsdps1.c
4401 
            Modify gs_rectfill to suppress direct access of a device's
4402 
            fill_rectangle method if both overprint and overprint mode are set
4403 
            to true. This is required to make sure the overprint compositor has
4404 
            access to pre-halftoned device color information with which to
4405 
            implement overprint mode.

        Split the half tone cache initialization into two pieces.  The halftone
4683 
        cache is now initialized just prior to being used in the various
4684 
        halftone render routines.  This was doe to prevent a problem with cache
4685 
        conflicts.  If the half tone cache is not large enough for a separate
4686 
        tile for each level then there could be a problem if two different
4687 
        device colors used the same cache entry but with different level values.

4693 
        This commit is to remove the change from yesterday.  That commit has
4694 
        some serious flaws.  It fixed a small problem by creating some larger ones.
4695 
 
4696 
        There is still a flaw in the logic of image_render_color.  It is creating
4697 
        a pair of device colors.  Unfortunately, the process of creating the second
4698 
        one can change a half tone cache used by the first.  This affects the final
4699 
        image when the first color is then used to image pixels.

        * gxicolor.c [1.3] (+27 -15):
4721 
        image_render_color creates a pair of device colors and then compares them.
4722 
        Unfortunately the process of creating the second device color can alter
4723 
        the halftone cache used by the first.  This can occur when the halftone
4724 
        cache is small (4096 bytes) and there is not enough room for a cache
4725 
        entry for each level.  The fix is to reload the cache by remapping the
4726 
        first color before it is used to render a pixel.
4727 
 
4728 
        Note:  This problem also affects non DeviceN code but is less visible
4729 
        since a large cache (100000 bytes) is used for many situations.

4757 
            Added code to create the setoverprintmode and currentoverprintmode
4758 
            operators.
4759 
 
4760 
          src/gconf.c
4761 
            Add the gx_compositor_list array, to list the set of compositor
4762 
            types compiled into the system. Also provided the gs_find_compositor
4763 
            procedure, to locate a compositor method vector based on its
4764 
            type identifier.
4765 
 
4766 
          src/gdevdgbr.c
4767 
            Fixed several bugs in gx_get_bits_copy, for cases in which the
4768 
            transfer of output data involves a skew (bit shift) but no color
4769 
            conversion (a case that is apparently used only by the overprint
4770 
            facility). This case uses the copy_mono method for the 1-bit
4771 
            memory device. The invocation of this method had two problems:
4772 
 
4773 
              1. The temporary device created for the transfer had uninitialized
4774 
                 width and height fields. Because copy_mono will invoke the
4775 
                 fit_copy macro, these fields must be set to reasonable values.
4776 
 
4777 
              2. The width passed to copy_mono must be bit-width, as the
4778 
                 method for a depth == 1 device is used. Previously, the
4779 
                 pixel width was used.
4780 
 
4781 
          src/gdevx.c
4782 
            Fixed a problem in x_copy_image. If the image passed to this routine
4783 
            contains more than one pixel, the colors_and and colors_or fields were
4784 
            not updated. Because these fields are only used for optimization, and
4785 
            properly updating them in this situation is potentially expensive,
4786 
            they are now just set to safe values (colors_and = 0;
4787 
            colors_or = (x_pixel)(-1)).
4788 
 
4789 
          src/genconf.c
4790 
            Added to "-comp" option to support construction of a list of
4791 
            compositors compiled into the system.
4792 
 
4793 
          src/gs.mak
4794 
            Added the SETCOMP and ADDCOMP macros, to provide access to the
4795 
            -comp option of genconf.c.
4796 
 
4797 
          src/gsalphac.c
4798 
            Exported the gs_composite_alpha_type structure, and added a compositor
4799 
            type identifier to this structure. Also modified the de-serialization
4800 
            (read) method for this size so that the data string provided be large
4801 
            enough but not necessarily exactly the right size, and to return the
4802 
            number of bytes actually read (or an error code).

4804 
          src/gscdefs.h
4805 
            Added a prototye for gs_find_compositor (see gconf.c above).
4806 
 
4807 
          src/gscolor.c
4808 
            Modified gx_set_device_color_1 to turn off overprint (and overprint
4809 
            mode).
4810 
 
4811 
          src/gsovc.c:
4812 
            1. Modified the de-serialization method (read) to return the number of
4813 
               bytes actually read (or an error code).
4814 
            2. Renamed gs_overprint_type to be gs_composite_overprint_type, so as
4815 
               to conform to the new convention for compositor names.
4816 
            3. For the overprint devices, set the get_xfont_procs, get_xfont_device,
4817 
               and text_begin methods to use the corresponding default methods,
4818 
               rather than the forwarding methods. Device-supported fonts are
4819 
               incompatible with overprint, as the required low-level calls may
4820 
               not be made. While the text_begin method is not itself a rendering
4821 
               method, it does record an imaging device, and this device must
4822 
               be the overprint device rather than the target device. If the
4823 
               forwarding text_begin method is used, the recorded imaging device
4824 
               would be the target device.
4825 
            4. Modified update_overprint_params to avoid use of the overprint
4826 
               devices for cases in which overprint is true, but all color
4827 
               components are to be drawn. Though the output is not changed, use
4828 
               of the non-overprint device improves performance in this case.
4829 
            5. Modified the default overprint compositor creation method
4830 
               (c_overprint_create_default_compositor) to ignore overprint
4831 
               requests if the current color model has only a single component.
4832 
               Overprinting can never have an effect in this situation, and
4833 
               avoiding these cases also avoids difficulties with mask caching
4834 
               devices (such as are used with the character cache).
4835 
 
4836 
          src/gsstate.c
4837 
            Modified gs_state_update_overprint to update the color model mapping
4838 
            procedures and unset the device color. Though updating the overprint
4839 
            status will never change the color model, the overprint devices
4840 
            require a special set of forwarding color model mapping procedures.
4841 
 
4842 
          src/gxclimag.c
4843 
            Implemented the clist_create_compositor procedure (the create_compositor
4844 
            method for the command list device).
4845 
 
4846 
          src/gxclpath.c
4847 
            Replaced the cmd_opv_put_params code (0xdf) with cmd_opv_extend. This
4848 
            code indicates that the subsequent byte should be read and interpreted
4849 
            as a command from the gx_cmd_ext_op enumeration. Currently, this
4850 
            enumeration has two elements, cmd_opv_ext_put_params (the put_params
4851 
            method) and cmd_opv_ext_create_compositor (the create_compositor
4852 
            method).
4853 
 
4854 
          src/gxclrast.c
4855 
            1. Made the code parsing changes required by the new cmp_opv_extend
4856 
               code (see gxclpath.h above).
4857 
            2. Added the read_create_compositor procedure, to interpret the
4858 
               cmd_opv_ext_create_compositor command.
4859 
 
4860 
          src/gxclutil.c
4861 
            Modified cmd_put_params for the new cmp_opv_extend/cmd_opv_ext_put_params
4862 
            coding techinque.
4863 
 
4864 
          src/gxcmap.c
4865 
            Modified gx_set_cmap_procs to handle devices that have no
4866 
            get_color_mapping_procs method (such as mask caching devices).
4867 
 
4868 
          src/gxcomp.h
4869 
            Added the comp_id field to the gs_composite_type_t structure. Also
4870 
            added macros for the alpha and overprint compositors (the only two
4871 
            compositors in the current system).
4872 
 
4873 
          src/gxoprect.c
4874 
            Fixed typo in pack_scanline_lt8: the source data pointer was not
4875 
            being advanced.
4876 
 
4877 
          src/gxoprect.h
4878 
            Fixed typo in RCS identifier comment.
4879 
 
4880 
          src/lib.mak
4881 
            1. Updated several dependency lists.
4882 
            2. Added code to generate the list of compiled compositors.

        The last version had a problem in that the gray calculation might miss
4947 
        the fact that the calculation had produced a solid color (due to rounding

4957 
        code set from ORIMP to enable overprint and overprint mode.
4958 
 
4959 
        New Files:
4960 
 
4961 
          src/gxoprect.c
4962 
          src/gxoprect.h
4963 
            These files provide the low-level code for the fill_rectangle method
4964 
            of the overprint compositor device. There are three such procedures,
4965 
            which are used in different circumstances:
4966 
 
4967 
              gx_overprint_generic_fill_rectangle is always applicable, but is
4968 
                very slow as it must decode and re-encode the color for each pixel.
4969 
 
4970 
              gx_overprint_sep_fill_rectangle_1 is applicable to separable and
4971 
                linear color encodings whose depth is a divisor of
4972 
                8 * sizeof(mono_fill_chunk) = 32. This is always the
4973 
                case if depth &lt;= 8. The code used in this case is, once past a
4974 
                large amount of setup, about as fast as can be achieved while
4975 
                using get_bits_rectangle.
4976 
 
4977 
              gx_overprint_sep_fill_rectangle_2 is applicable to all other
4978 
                separable and linear color encodings (all of which will have
4979 
                depth % 8 = 0). This uses a byte-wise method which is in principle
4980 
                slower than what could be achieved with a chunk-wise method, but
4981 
                is much easier to code in the general case (i.e.: for multiple
4982 
                possible depths). It will likely be faster in practice.
4983 
 
4984 
        Modified Files:
4985 
 
4986 
          lib/gs_init.ps
4987 
          lib/gs_setpd.ps
4988 
            Modified erasepage (and several other bits of code that erase the
4989 
            page) to turn off overprint before filling the page. This is necessary
4990 
            to preserve the meaning of erasepage.
4991 
 
4992 
          src/gsbitops.c
4993 
          src/gsbitops.h
4994 
            Added the bits_fill_rectangle_masked procedure, a generalization of
4995 
            the bits_fill_rectangle procedure that allows for a component mask.
4996 
            Also generalized bits_fill_rectangle (and bits_fill_rectangle_masked)
4997 
            to support depth &gt; 8, so long as
4998 
            (8 * sizeof(mono_fill_chunk)) % depth = 0.
4999 
 
5000 
            Currently, bits_fill_rectangle_masked is used only by the overprint
5001 
            compositor device, but it can also be used by devices that can
5002 
            directly implement overprint (such as the memory device).
5003 
 
5004 
          src/gscdevn.c
5005 
            Modified check_DeviceN_component_names to initialize the
5006 
            component_map.sep_type field of the imager state to SEP_OTHER.
5007 
            Previously this field was not set for DeviceN color spaces, which
5008 
            confused some of the overprint code.
5009 
 
5010 
          src/gsovrc.c
5011 
            Implemented the real overprint_fill_rectangle procedures. As part of
5012 
            this work, added the local procedure swap_color_index, that swaps
5013 
            bytes in a color index as required to work with byte-oriented bitmaps
5014 
            on little-endian devices (only if depth &gt; 8).
5015 
 
5016 
            Also fixed a parity bug in the creation of the retain_mask.
5017 
 
5018 
          src/gsovrc.h
5019 
            Fixed typo (/* $Id: History7.htm,v 1.44 2005/10/20 19:46:23 ray Exp $Id: History7.htm,v 1.44 2005/10/20 19:46:23 ray Exp $ */).
5020 
 
5021 
          src/gxdcconv.c
5022 
            Modified color_rgb_to_cmyk to work if the imager state pointer
5023 
            operand is a null pointer. Note that in this case full undercolor
5024 
            removal and black generation will be performed, which is consistent
5025 
            with other such conversions in the code that do not have access to
5026 
            the imager state, but differs from the mapping used if the imager
5027 
            state is available but has no blackgeneration or undercolor removal
5028 
            map.
5029 
 
5030 
          src/lib.mak
5031 
            Added the gxoprect.$(OBJ) target and included this as a dependency
5032 
            in LIB4s. Also updated some other dependency lists.
5033 
 
5034 
 
5035 
        Additional file modified (not for overprint but needed for release):
5036 
 
5037 
          src/gdevdflt.c
5038 
            Added code to select a reasonable default value for the decode_color
5039 
            method, as this method is used extensively by the generic overprint
5040 
            implementation routines. The modifications are just a first pass to
5041 
            allow us to test the overprint code; they are not intended as a
5042 
            final solution.

        Notes:
5106 
 
5107 
         Modified files:
5108 
 
5109 
          gsstate.c
5110 
            Added code to ignore an error return from the create_compositor call
5111 
            in gs_state_update_overprint if the call was made to turn off
5112 
            overprint. This avoids errors for device configurations that do not
5113 
            (yet) support the create_compositor call, when running files that do
5114 
            not require overprint support.
5115 
 
5116 
          gsovrc.h
5117 
            Fixed a typo in a commment.
5118 
 
5119 
          gxclrast.c
5120 
            Fixed a re-entrancy problem in read_set_color_space that was introduced
5121 
            by the previous modification to this file.
5122 
 
5123 
          gsimage.c
5124 
            Added a comment concerning re-entrancy, and slightly modified another
5125 
            comment.
5126 
 
5127 
          gscspace.c
5128 
            Added some comments concerning re-entrancy.
5129

5133 
 
5134 
          src/gsovrc.c
5135 
            Added full compositor device "plumbing". The overprint compositor
5136 
            now does all of the required device creation and setup work. The
5137 
            only piece still missing are implementations of the low-level
5138 
            rendering routines that actually implement overprint.
5139

          src/gsptype1.c

5145 
          src/gxht.c
5146 
          src/gxpcolor.h
5147 
            Added the method get_nonzero_comps to the gx_device_color_type_t
5148 
            structure (the gx_device_color methods). This method is used by
5149 
            the overprint code to determine which color component intensities
5150 
            have non-zero value, which must be known to implement overprint
5151 
            mode.
5152 
 
5153 
          src/gsovrc.h
5154 
          src/gscspace.c
5155 
            Changed the drawn_comps field of the gs_overprint_params_t
5156 
            structure from a byte array to a gx_color_index. This is a bit
5157 
            ugly, as the value is a bit map rather than an encoded color,
5158 
            but allows much simpler processing. (As in device colors, a
5159 
            gx_color_index is used because it is known to be large enough.
5160 
 
5161 
          src/lib.mak
5162 
            Updated dependency list for gsovrc.$(OBJ).

            Implementation of the overprint compositor. For the moment, this is
5170 
            just a stub. This file will grow considerably in the next two releases.
5171 
 
5172 
 
5173 
          src/gsovrc.h
5174 
            Interface to the overprint compositor. This is in essentially final
5175 
            form, even though only a stub implementation of the compositor is
5176 
            available. This file also includes a lengthy comment describing when
5177 
            the compositor must be updated.

5192 
            Incorporated an optimization of setcolorspace from the casper head.
5193 
            The optimization avoids setting the color space if it is the same as
5194 
            the current color space. gs_icc.ps also contains a fix for a bug
5195 
            in the handling of DataSources that are streams (rather than strings;
5196 
            Dan discovered and analyzed this bug).
5197 
 
5198 
            Note that this is a fairly complex optimization, and there were many
5199 
            problems with the head code that needed to be resolved. Among these
5200 
            were:
5201 
 
5202 
              1. An invocation of setcolorspace should always set the default
5203 
                 color for the operand color space, even if that color space is
5204 
                 identical to the current color space.
5205 
 
5206 
              2. If UseCIEColor is true, setcolorspace must be executed if
5207 
                 the operand color space involves device-specific color spaces.
5208 
                 This is because the Default{Gray,RGB,CMYK} instances of the
5209 
                 ColorSpace resource category may have changed.
5210 
 
5211 
              3. When UseCIEColor is changed from true to false in setpagedevcie,
5212 
                 the implicit initgraphics invocation must perform a setcolorspace
5213 
                 operation, even if the current color space is DeviceGray. This
5214 
                 is necessary to ensure that the un-substituted DeviceGray color
5215 
                 space is set as the current color space.
5216 
 
5217 
 
5218 
          lib/gs_init.ps
5219 
            In /showpage, replace the sequence "erasepage ... initgraphics" with
5220 
            "initgraphics 1 setcolor .fillpage 0 setcolor". This has the desired
5221 
            effect, and avoids two unnecessay invocations of setcolorspace.
5222 
 
5223 
 
5224 
          lib/gs_setpd.ps
5225 
            1. Modified the currentpagedevice pseudo-operator for cases in which
5226 
               the stored page device must be copied. Previously, the new copy
5227 
               was allocated in the current VM mode, which could cause
5228 
               invalidaccess errors if currentpagedevice was invoked while in
5229 
               global VM mode and composite objects stored in the page device
5230 
               dictionary were in local VM (this problem is present in the PS3
5231 
               FTS). The new code will allocate the copy in the save VM as the
5232 
               original dictionary.
5233 
 
5234 
            2. In setpagedevice, added code to set current color space to
5235 
               something other than DeviceGray if modification of the page device
5236 
               will set UseCIEColor to false. This is necessary for the
5237 
               setcolorspace optimization to function properly (see above).
5238 
 
5239 
            3. In the .postinstall pseudo-operator, replaced "erasepage initgraphics"
5240 
               with "initgraphics 1 setcolor .fillpage 0 setcolor". This avoids
5241 
               two unnecessary invocations of setcolorspace.
5242 
 
5243 
 
5244 
          src/gdevp14.c
5245 
            Added the pdf14_create_compositor method. This method will check if
5246 
            the compositor to be created is the overprint compositor. If so,
5247 
            the request to create the compositor will simply be ignored, as
5248 
            the gs_pdf14_device and its associated marking device must implement
5249 
            overprint directly.
5250 
 
5251 
 
5252 
          src/gscdevn.c
5253 
            1. Removed the equality check method.
5254 
 
5255 
            2. Added the set_overprint method for DeviceN color spaces.
5256 
 
5257 
 
5258 
          src/gscolor2.c
5259 
            1. Removed the equality check method.
5260 
 
5261 
            2. Added the set_overprint method for Indexed color spaces.
5262 
 
5263 
 
5264 
          src/gscpixel.c
5265 
            1. Removed the equality check method.
5266 
 
5267 
            2. Added the set_overprint method for DevicePixel color spaces.
5268 
 
5269 
 
5270 
          src/gscscie.c
5271 
            1. Removed the equality check method.
5272 
 
5273 
            2. Added the set_overprint method for CIEBased color spaces.
5274 
 
5275 
 
5276 
          src/gscsepr.c
5277 
            1. Removed the equality check method.
5278 
 
5279 
            2. Added the set_overprint method for Separation color spaces.
5280 
 
5281 
            3. Moved the gs_{set|current}overprint[mode] procedures to gsstate.c.
5282 
 
5283 
 
5284 
          src/gscsepr.h
5285 
            Moved prototypes for the gs_{set|current}overprint[mode] procedures
5286 
            to gsstate.h.
5287 
 
5288 
 
5289 
          src/gscspace.c
5290 
            1. Removed the color space equality check methods for the device-
5291 
               specific color spaces.
5292 
 
5293 
            2. Added the basic set_overprint procedures, to provide color-space
5294 
               specific setting of the overprint compositor.
5295 
 
5296 
            3. Modified the gs_cspace_{build|init}_Device{Gray|RGB|CMYK}
5297 
               procedures to use the same identifier for all instances of
5298 
               the parameterless color spaces (i.e.: all DeviceGray instances
5299 
               will have the same id, as will all DeviceRGB instances, but the
5300 
               id for any DeviceGray will differ from the id for a DeviceRGB
5301 
               instance). This enables an optimization in the gs_setcolorspace
5302 
               routine that had been lost in the previous code modification.
5303 
 
5304 
 
5305 
          src/gscspace.h
5306 
            Removed prototype for the gs_color_space_equal procedure.
5307 
 
5308 
 
5309 
          src/gsicc.c
5310 
            1. Removed the equality check method.
5311 
 
5312 
            2. Added the set_overprint method for ICCBased color spaces.
5313 
 
5314 
 
5315 
          src/gslib.c
5316 
            Modified test9 to explicitly reset the current color space; this
5317 
            is no longer done by gs_initgraphics.
5318 
 
5319 
 
5320 
          src/gspcolor.c
5321 
            Added set_overprint method for pattern color spaces, removed the
5322 
            equality check method.
5323 
 
5324 
 
5325 
          src/gsstate.c
5326 
            1. Added code to update the overprint compositor when the current
5327 
               color space, current device, overprint, or overprint mode
5328 
               settings change. Included in this change is code in gs_grestore_only
5329 
               that updates the overprint compositor as part of the grestore
5330 
               operation when this is required.
5331 
 
5332 
            2. Moved the gs_{set|current}overprint[mode] procedures to this file
5333 
               from gscsepr.c. This is more convenient for the new code, and
5334 
               gscsepr.c was never a particularly appropriate place for these
5335 
               routines.
5336 
 
5337 
            3. Modified gs_initgraphics to not reset the current color space or
5338 
               current color. For PostScript this must now be done in the
5339 
               PostScript code to properly handle color space substitution.
5340 
               Other clients that use this procedure (the XL interpreter is the
5341 
               only one (aside from gslib.c)) can easily reset these parameters
5342 
               as well.
5343 
 
5344 
 
5345 
          src/gsstate.h
5346 
            Moved prototypes for the gs_{set|current}overprint[mode] procedures
5347 
            here from gscsepr.h.
5348 
 
5349 
 
5350 
          src/gxccache.c
5351 
            Modified gx_image_cached_char to just return if the current color
5352 
            is a pure gx_no_color_index (transparent).
5353 
 
5354 
 
5355 
          src/gxcspace.h
5356 
            1. Removed the equality check method.
5357 
 
5358 
            2. Added the set_overprint method.
5359 
 
5360 
 
5361 
          src/gxipixel.c
5362 
            Modified the gx_image_enum_begin to allow the Decode array for
5363 
            imagemasks to have any two distinct numbers, rather than just 0 and
5364 
            1. This matches the behavior of all Adobe systems (though not the
5365 
            documentation), and avoids some spurious failures when running the
5366 
            FTS.
5367 
 
5368 
 
5369 
          src/gxpcmap.c
5370 
            Modified pattern_accum_copy_mono to just return if both the foreground
5371 
            and background colors are gx_no_color_index (transparent). If this is
5372 
            not done, the mask device's copy_mono procedure may generate an
5373 
            error when invoked (this is true for mem_mono_copy_mono).
5374 
 
5375 
 
5376 
          src/iutil.c
5377 
            Modified obj_eq to consider two 0-length arrays to be equal,
5378 
            irrespective of their type and their pointers (the latter aren't
5379 
            meaningful if the array length is 0). This matches the PostScript
5380 
            documentation and the behavior of Adobe systems. It also fixes
5381 
            some spurious failures in the FTS.
5382 
 
5383 
 
5384 
          src/lib.mak
5385 
            Added an entry for gsovrc (the overprint compositor), and updated
5386 
            various dependency lists.
5387 
 
5388

          src/zfdcte.c
5390 
            Modified the DCTEncode procedure (zDCTE) to allocate the
5391 
            jpeg_compress_data and subsidiary memory structures in current VM.
5392 
            Previously these structures were allocated in gs_default_memory,
5393 
            which does not support garbage collection. Since the structures
5394 
            were subject to garbage collection and relocation, chaos could
5395 
            and, in the case of FTS file 119-28.ps, did ensue.
5396 
 
5397 
            Note that these structure must be allocated immovable, which
5398 
            requires a considerable amount of overhead when using VM. A better
5399 
            approach would be to allocate them in gs_default_memory, and use
5400 
            a more sophisticated structure descriptor for the stream_DCT_state
5401 
            structure (st_DCT_state).

5404 
          src/zgstate.c
5405 
            Slightly simplified zinitgraphics, and updated a comment in this
5406 
            procedure.
5407 
 
5408 
 
5409 
          src/zmisc.c
5410 
            Modified realtime operator to set a zero point at boot time. This
5411 
            avoids an annoying delay in running FTS panel 211-01 (206-01.ps).
5412 
 
5413 
 
5414 
          zpcolor.c
5415 
            Modified the pattern_paint_prepare procedure to use gs_setdevice_no_int
5416 
            rather than gx_set_device_only. It is not clear why the latter
5417 
            procedure was ever used in this location, and it is now important to
5418 
            use the former procedure so the overprint compositor may be properly
5419 
            updated.

        Overprint implementation (Jan Stoeckenius)
5497 
 
5498 
        This is a preliminary code release for the overprint capability. The
5499 
        release does not contain the overprint facility itself; it consists
5500 
        entirely of modifications so that color space changes will occur in a
5501 
        predictable fashion.

5512 
        Files added:
5513 
 
5514 
          lib/gs_cspace.ps      PostScript portion of the basic color space handling;
5515 
                                see the extensive comment at the head of the file
5516 
                                for information. Note that color space substitution
5517 
                                and the hue-saturation-brightness (HSB) color space
5518 
                                are now fully implemented in the PostScript code;
5519 
                                the interpreter and the graphic library are no longer
5520 
                                involved in or even aware of these features.
5521 
 
5522 
          lib/gs_devcs.ps       Implementation of the DeviceGray, DeviceRGB, and
5523 
                                DeviceCMYK color spaces.
5524 
 
5525 
          lib/gs_ciecs2.ps      Implementation of the LangaugeLevel 2 CIEBased color
5526 
                                spaces: CIEBasedA and CIEBasedABC.
5527 
 
5528 
          lib/gs_ciecs3.ps      Implementation of the LanguageLevel 3 CIEBased color
5529 
                                spaces: CIEBasedDEF and CIEBasedDEFG
5530 
 
5531 
          lib/gs_devpxl.ps      Implementation of the DevicePixel color spaces
5532 
 
5533 
          lib/gs_indxd.ps       Implementation of the Indexed color space.
5534 
 
5535 
          lib/gs_sepr.ps        Implementaton of the Separation color space.
5536 
 
5537 
          lib/gs_devn.ps        Implementation of the DeviceN color space.
5538 
 
5539 
          lib/gs_patrn.ps       Implementation of the Pattern color space.
5540 
 
5541 
 
5542 
          lib/gs_img.ps         Implementation of the traditional (non-dictionary)
5543 
                                form of the image and imagemask operators, and the
5544 
                                colorimage operator (including the Next alphaimage
5545 
                                facility). The interpreter now provides only the
5546 
                                dictionary form of the image and imagemask operators,
5547 
                                including a variation that provides alpha-channel
5548 
                                support.
5549 
 
5550 
                                Also modified the handling of color spaces for
5551 
                                ImageType 2 images. This slightly changes the behavior
5552 
                                of these images. If PixelCopy is defined to be true
5553 
                                in the image dictionary but such a copy cannot be
5554 
                                supported, an error will be generated. This is in
5555 
                                agreement with Adobe's documentation, but differs
5556 
                                from the earlier behavior.
5557 
 
5558 
          The code for Indexed, Separation, and DeviceN color spaces
5559 
          incorporates code, courtesy of Dan, that will invoke the lookup or
5560 
          tint transform procedure in the appropriate context if this is
5561 
          appropriate (if there is a lookup procedure for Indexed color spaces
5562 
          or the alternate color space is in use for Separation and DeviceN
5563 
          color spaces). Currently this is not done recursively (if an Indexed
5564 
          color space has a DeviceN base color space, for example), but that
5565 
          has not proven necessary in practice. If necessary, it can be added.
5566 
 
5567 
 
5568 
          src/zcolor3.c         Code to implement the .setuseciecolor operator. This
5569 
                                operator is used only in the setpagedevice code, and
5570 
                                makes certain that the use_cie_color field in the
5571 
                                interpreter's graphic state mirrors the setting of
5572 
                                the UseCIEColor page device parameter.
5573 
 
5574 
 
5575 
        Files modified:
5576 
 
5577 
          lib/gs_dpnxt.ps       Added PostScript implementation of the alphaimage
5578 
                                operator. This uses the internal .alphaimage
5579 
                                operator, which is a variation of the image
5580 
                                operator that provide alpha-channel support.
5581 
 
5582 
          lib/gs_icc.ps         Rewritten to implement the ICCBased color space
5583 
                                in the new scheme. See the comments in
5584 
                                lib/gs_cspace.ps for information.
5585 
 
5586 
          lib/gs_init.ps        Modified to include gs_cspace.ps, gs_devcs.ps,
5587 
                                and gs_img.ps, and to remove img_util_dict and
5588 
                                .cspace_util_dict from userdict at the end of
5589 
                                initialization.
5590 
 
5591 
          lib/gs_lev2.ps        All explicit color spaces removed (with one
5592 
                                exception, and replaced by inclusion of gs_devpxl.ps,
5593 
                                gs_ciecs2.ps, gs_indxd.ps, gs_sepr.ps, and
5594 
                                gs_patrn.ps. The only remaining color space support
5595 
                                feature is moving the setcolorspace and setcolor
5596 
                                pseudo-operators, and the colorspacedict dictionary,
5597 
                                to level2dict. This must be done here, as it is not
5598 
                                known that level2dict exists when gs_cspace.ps is
5599 
                                first run.
5600 
 
5601 
                                Also removed all explicit image support. This is
5602 
                                now handled by gs_img.ps (see above).
5603 
 
5604 
          lib/gs_ll3.ps         Removed the old support for color space substitution;
5605 
                                this is now handled directly by the color space
5606 
                                code (see the comments in gs_cspace.ps for
5607 
                                information). Added inclusion of gs_ciecs3.ps and
5608 
                                gs_devn.ps.
5609 
 
5610 
          lib/gs_setpd.ps       Added support for the .getuseciecolor and
5611 
                                .setuseciecolor operators. This maintains a
5612 
                                "mirror" of the UseCIEColor parameter in the
5613 
                                graphic state, to allow fast access.
5614 
 
5615 
          src/gdevnfwd.c        In gx_forward_get_color_mapping_procs, added a check
5616 
                                for the case of a target device which has no
5617 
                                get_color_mapping_procs procedure. This led to a
5618 
                                segmentation violation crash for FTS file 296-01.ps
5619 
                                The fix may not be the correct one, as we are not
5620 
                                certain why a device would lack this method.
5621 
 
5622 
          src/gdevp14.c         Replaced a use of the shared field in the graphic state
5623 
                                with a color space allocated on the C-language stack.
5624 
 
5625 
          src/gdevpsdi.c        Replaced an instance of use of the gs_cspace_DeviceRGB
5626 
                                procedure.
5627 
 
5628 
          src/gscolor.c         Removed gs_currentgray and gs_currentrgbcolor. Modified
5629 
                                gs_setgray and gs_setrgbcolor to use gs_setcolorspace
5630 
                                and gs_setcolor. This eliminates use of the
5631 
                                gs_current_Device*_space routines.
5632 
 
5633 
          src/gscolor.h         Removed prototypes for gs_currentgray and
5634 
                                gs_currentrgbcolor.
5635 
 
5636 
          src/gscolor1.c        Removed gs_currentcmykcolor. Modified gs_setcmykcolor
5637 
                                to use gs_setgray and gs_setcolorspace.
5638 
 
5639 
          src/gscolor1.h        Removed prototype for gs_currentcmykcolor.
5640 
 
5641 
          src/gscolor2.c        Removed gs_currentcolorspace_index. Removed the color
5642 
                                index tracking used as part of the color space
5643 
                                substitution method.
5644 
 
5645 
          src/gscolor2.h        Removed prototype for gs_currentcolorspace_index.
5646 
 
5647 
          src/gscscie.c         Eliminated use of the gs_cspace_Device* routines.
5648 
 
5649 
          src/gscsepr.c         Fixed a pair of typos in revision 1.6 of the code.
5650 
                                In gs_cspace_set_sepr_proc and
5651 
                                gx_concretize_Separation, the code was still accessing
5652 
                                pcspace-&gt;params.device_n when it wanted to access
5653 
                                pcspace-&gt;params.separation. This caused a crash in
5654 
                                FTS file 245-01.ps.
5655 
 
5656 
          src/gscspace.c        Removed gs_cspace_Device* procedures.
5657 
 
5658 
          src/gscspace.h        Removed prototypes for gs_cspace_Device* procedures.
5659 
 
5660 
          src/gsimage.c         Removed use of the gs_cspace_DeviceGray procedure.
5661 
 
5662 
          src/gsiparam.h        Removed the gs_image_t_int_{gray, rgb, cmyk} macros.
5663 
 
5664 
          src/gsistate.c        Updated code to reflect removal of the shared field in
5665 
                                the imager state. As part of this, the
5666 
                                rc_free_imager_shared and gx_device_color_spaces_free
5667 
                                procedures were removed.
5668 
 
5669 
          src/gslib.c           Removed use of the gs_current_Device*_space and
5670 
                                gs_image_t_init_gray procedures.
5671 
 
5672 
          src/gspcolor.c        Removed reference to the orig_cspace_index field,
5673 
                                which is no longer part of the library's graphic
5674 
                                state.
5675 
 
5676 
          src/gsptype1.c        Eliminated use of the gs_cspace_DeviceGray procedure,
5677 
                                and insured that a color space is set as the current
5678 
                                color space before it is used.
5679 
 
5680 
          src/gsstate.c         Removed code that maintained the device_color_spaces
5681 
                                field (color space substitution), which is no longer
5682 
                                in the library's graphic state.
5683 
 
5684 
          src/gxclrast.c        Removed use of the gs_cspace_Device* procedures.
5685 
 
5686 
          src/gximage3x.c       Removed use of the gs_image_t_init_gray procedure.
5687 
 
5688 
          src/gximage2.c        Modified color space handling for ImageType 2 images.
5689 
                                Note that there was and still is a problem with the
5690 
                                handling of transformations in this code.
5691 
 
5692 
          src/gxistate.h        Removed the shared field of the imager state, all
5693 
                                associated structures and prototypes, and modified
5694 
                                the affected GC macros. The gx_device_color_spaces_t
5695 
                                structure was previously used in the graphic library's
5696 
                                state as well, but that use has been eliminated.
5697 
 
5698 
          src/gzstate.h         Removed the the device_color_spaces field, and modified
5699 
                                the requisite GC macros
5700 
 
5701 
          src/idparam.c         Modified dict_float_array_check_param to handle
5702 
                                packed (short or mixed) arrays.
5703 
 
5704 
          src/igstate.h         Added the use_cie_color field. This is a mirror for
5705 
                                the UseCIEColor parameter of the page device, used
5706 
                                because the currentpagedevice operator is potentially
5707 
                                expensive.
5708 
 
5709 
          src/iimage.h          Modified to restrict the interpreter to just the
5710 
                                dictionary form of the image and imagemask operator.
5711 
                                This removes the zimage_opaque_setup, zimage_data_setup,
5712 
                                and zimage_multiple prototypes, and moves the
5713 
                                image_params structure and the image1_setup
5714 
                                prototypes to this file (from iimage2.h).
5715 
 
5716 
          src/iimage2.h         Moved everything except the prototype for
5717 
                                process_non_source_image to iimage.h.
5718 
 
5719 
          src/iutil.c           Added process_float_array procedure, to allow packed
5720 
                                (short, mixed) arrays of numbers to be handled.
5721 
 
5722 
          src/iutil.h           Added prototype for the process_float_array procedure.
5723 
 
5724 
          src/zcolor.c          Removed:
5725 
                                  zcurrentgray, zcurrentrgbcolor,
5726 
                                  setgray, setrgbcolor
5727 
                                Moved (from zcolor2.c):
5728 
                                  zcurrentcolor, zcurrentcolorspace,
5729 
                                  zsetcolor, zsetcolorspace
5730 
                                Added:
5731 
                                  zgetuseciecolor   queries the use_cie_color field
5732 
                                                    in the interpreter state
5733 
                                  zsetdevcspace     sets a DeviceGray, DeviceRGB, or
5734 
                                                    DeviceCMYK color space
5735 
 
5736 
          src/zcolor1.c         Removed zcurrentcmykcolor, zsetcmykcolor, and
5737 
                                zcolorimage.
5738 
 
5739 
          src/zcolor2.c         Removed everything in prior version. Added
5740 
                                zusealternate, to test if an alternate color space
5741 
                                is being used (for a Separation, DeviceN, or ICCBased
5742 
                                color space), or if a base color space is in use
5743 
                                (for an Indexed or a Pattern color space that uses
5744 
                                a base space).
5745 
 
5746 
          src/zdpnext.c         Replace the alphaimage operator with .alphaimage,
5747 
                                which has the semantics of the dictionary form of
5748 
                                the image operator.
5749 
 
5750 
          src/zgstate.c         Modified the initgraphics operator to set the
5751 
                                colorspace.array field to a legitimate color space
5752 
                                (previously it was set to a null object). Also
5753 
                                inserted code to initialize the use_cie_color field
5754 
                                to false.
5755 
 
5756 
          src/zimage.c          Removed the traditional-form image and imagemask
5757 
                                operators (zimage and zimagemask), and moved the
5758 
                                dictionary form of these operators to this file
5759 
                                from zimage2.c. Also, added the has_alpha parameter
5760 
                                to the data_image_params and pixel_image_params
5761 
                                procedures, to support the .alphaimage operator.
5762 
 
5763 
          src/zimage2.c         Moved everything except the process_non_source_image
5764 
                                procedure to zimage.c.
5765 
 
5766 
          src/zimage3.c         Updated calls to data_image_params and
5767 
                                pixel_image_params to add has_alpha parameter.
5768 
 
5769 
          src/zmisc3.c          Removed .setsubstitutecolorspace operator.
5770 
 
5771 
          src/zpcolor.c         Modified .setpatternspace to handle a packed (short,
5772 
                                mixed) array operand.
5773 
 
5774 
          src/zshade.c          Modified build_mesh_shading to handle a packed (short,
5775 
                                mixed) DataSource array operand.
5776 
 
5777 
          src/ztrans.c          Modified calls to data_image_params and
5778 
                                pixel_image_params to add has_alpha operand.
5779 
 
5780 
          src/watclib.mak       Removed reference to the hsblib.dev, which no longer
5781 
                                exists and which, for some unknown reason, was directly
5782 
                                included in this makefile. Does anyone still use this
5783 
                                file?
5784 
 
5785 
          src/int.mak           Removed hsb.dev and the zimage2_l2 operators, added
5786 
                                zcolor3.c, updated various dependency lists.
5787 
 
5788 
          src/lib.mak           Removed hsblib.dev and gscssub.[ch], updated various
5789 
                                dependency lists. Note that this file has not yet
5790 
                                been modified to always compile with Level 3 support.

5815 
        1. Revised version of the Separation color space implementation.  The /None
5816 
        case now works.  The "normal" case is now implemented as part of the separation
5817 
        color space instead of using the DeviceN logic.
5818 
        2. The Separation and DeviceN color space handler for getting the alternate
5819 
        color space now return NULL if the alternate color space is not being used.
5820 
        (As pere request from ORIMP.)
5821 
        3. The DeviceN color space had a problem with an ICC alternate space. Corrected.

        Apply RGB-&gt;device and CMYK-&gt;device profiles only in DeviceN color model;
5843 
        in DeviceRGB and DeviceCMYK color models, the mapping is defined by

        Makes xcfcmyk device agile in ProcessColorModel. Changes "expert

        * lib.mak [1.11] (+3 -2), int.mak [1.4] (+3 -2):
5858 
        These two files should have been included in the previous commit.

        gscsepr.c [1.5] (+84 -176), gscdevn.h [1.5] (+9 -6), gscdevn.c [1.7] (+25 -19):
5864 
        Changed the separation color space to use common logic with the DeviceN
5865 
        color space.  This commit also brings the DeviceN code up to date.  This
5866 
        includes the function sampling logic in zfsample.c.  This code handles the
5867 
        /All case and the normal separation case.  The /None case is not handled
5868 
        correctly.  All components are erased (zeroed) when /None is selected.
5869 
 
5870 
        * gscspace.h [1.6] (+3 -1):
5871 
        I was over zealous in cleaning up this file.  Restored defintion of
5872 
        gx_indexed_map.

5878 
        devs.mak [1.10] (+2 -2):
5879 
        These changes are required to initialize the "display" device to work
5880 
        with the DeviceN code.  This involves setting up the correct color_info
5881 
        structure for the device and the DeviceN related procs.

5892 
        * gdevdevn.c [1.8] (+2 -3):
5893 
        Some more corrections to the initialization of the spotrgb and spotcmyk
5894 
        device structures.  Apologies to Henry.  I misunderstood the results from
5895 
        the cvs merge.  Henry did not mangle the bpp, etc. in the previous commit.

5900 
        * gxdither.h [1.4] (+10 -10):
5901 
        Added prototype for function gx_render_device_DeviceN.
5902 
        Removed some unused macro definitions.
5903 
 
5904 
        * lib.mak [1.10] (+2 -2), gxcmap.c [1.9] (+49 -31):
5905 
        1.  Added included of string_.h.  This resolves some undefined function
5906 
        prototypes.
5907 
        2.  Corrected handling of transfer functions and halftoning.  (Transfer
5908 
        functions were not being applied if halftoning was being done.)
5909 
        3.  Finished the half tone code for DeviceN color model devices.
5910 
        4.  Some misc code clean up to remove misc warning messages.

5915 
        * gsht1.c [1.5] (+2 -2):
5916 
        We were not allocating a half tone cache for the "gray" component.
5917 
 
5918 
        * gdevdevn.c [1.7] (+22 -15):
5919 
        1.  Convert the spotcmyk device back to a half toned (1 bit per pixel per
5920 
        component) device.  This had been changed by Henry is the last commit.
5921 
        2.  Corrected the gray color space to cmyk color model handler.  This was
5922 
        corrupting the cmykspot colors.
5923 
        3.  Corrected a couple of problems in the spotcmyk device.  (Garbage data
5924 
        in the last half of byte if a line had an odd number of pixels.  Bad bps
5925 
        and planes in the pcx header - the cmyk pcx output file is really a 4 bit
5926 
        device with a color mapping table.)

5933 
        built with pcl.  This is a long standing issue supported by a thousand

6054 
        operand changes and misc. fixes for compiling pcl.  I used pcl because
6055 
        it was not clear how even to compile the gslib target.  With
6056 
        implementations for gs_ht_set_mask_comp() and
6057 
        gs_ht_set_threshold_comp() it will be possible to build pcl and verify
6058 
        the changes to these files from pcl.

6064 
        pdf_update_transfer() was not returning a value resulting in the

        previously encountered pdf problems.  It now retuns 0 and prints a
6066 
        diagnostic message saying it is not implemented.  Setting the

        as its type.  (May create a problem on Irix 5.2.)

        * gxcht.c [1.9] (+46 -48):

6517 
        * gxcht.c [1.8] (+6 -5):
6518 
        THis fix corrects the halftone hander which is used to handle more than four
6519 
        components.  It ws not correctly handling the mixture of a fully saturated
6520 
        component and some halftoned components.  (Worked with zero value components.)

6525 
        * gxcht.c [1.7] (+13 -6):
6526 
        This corrects a problem with some magenta coloring around the muzzle of
6527 
        the tiger.eps file when using the pcxcmyk device.
6528 
 
6529 
        Note:  There is still some stuff to check.  This fix primarily uses
6530 
        special code for 1 bit cmyk colors (same as previous versions of GS).
6531 
        The non 1 bit routines should produce the same result do not.

        * gxcht.c [1.6] (+16 -38):
6537 
        Corrected problems in set_ht_colors_le_4 which was preventing it from
6538 
        compiling.  This is the halftoner for non single bit 4 or less components.

        * unix-gcc.mak [1.5] (+3 -8), gdevm48.c [1.4] (+2 -2):
6544 
        The pixel size was incorrectly set to 3 instead of six (jan).  Adds
6545 
        CPPFLAG define for the long long so it works properly with raph's xcf
6546 
        device.

6551 
        * gxcht.c [1.5] (+13 -14):
6552 
        Corrects a problem with an unknown error being returned in 'fill' when
6553 
        drawing tiger.ps using the pcxcmyk device.  Some of the color halfoning
6554 
        code is disabled because it is not compatible with the devicen device
6555 
        color mapping routines.  This fix corrects some of these problems.
6556 
 
6557 
 
6558 
        Note:  There are still more problems in this module related to the DeviceN
6559 
        implementation.  There are many places that that assume 3 or 4 colors
6560 
        only.
6561 
 
6562 
        * gdevm40.c [1.4] (+2 -2):
6563 
        Matching change to the change in gdevm48.c.  Changed a hard coded value
6564 
        of 3 for the pixel size to PIXEL_SIZE.  The 3 was a holdover from code
6565 
        copied from gdevm24.c.  Note: gdevm56.c and gdevm64.c are already
6566 
        correct.

        previously inserted.  As per request for Jan. S.

6589 
        the interface for setting up a halftone.

6765 
        2.  First pass at getting the transfer functions (and some of the half
6766 
            tones) based upon the colorant names.  Note:  This still does not
6767 
            work but we want to get a first pass into CVS.

7243 
          lib/gs_cspace.ps
7244 
            Added _setcolorspace_nosub, a variation of the setcolorspace operation that
7245 
            avoids color space substitution. This is required for ICCBased color spaces,
7246 
            as they may be used to substitute for a device-specific color space, but
7247 
            use that same device-specific color space as an alternative space. If the
7248 
            alternative space was used (or even if it wasn't, in the prior code), an
7249 
            infinite loop would result (the eventual error is execstackoverflow).
7250 
 
7251 
          lib/gs_icc.ps
7252 
            Modified the cs_install routine for ICCBased color spaces to use the new
7253 
            _setcolorspace_nosub procedure.
7254 
 
7255 
          lib/pdf_draw.ps
7256 
            Removed the color substitution scheme used by resolvecolorspace. This has
7257 
            been superseded by the PostScript-based scheme.
7258 
 
7259 
          lib/pdf_main.ps
7260 
            Implemented color space substitution using PostScript's method. This works
7261 
            for all color spaces and, with the above noted modifications to
7262 
            gs_cspace.ps and gs_icc.ps, avoids infinite-loop problems. The
7263 
            earlier code did not implement color space substitution for
7264 
            DeviceCMYK (the code was just missing) and in rare cases could
7265 
            suffer from infinite loops.
7266 
 
7267 
          src/zcolor.c
7268 
            Correct a typo: the .setdevcspace operator was included twice in the

        The following should be prominently posted in full view of all
7284 
        software engineers:
7285 
 
7286 
          ***Do not use caches to hold unreplaceable data***
7287 
 
7288 
        Failure to follow that rule of good programming is the heart of the
7289 
        problem with FTS panel 245-04 (file 245-01.ps).
7290 
 
7291 
        The immediate cause of the problem is the optimization put in the
7292 
        setcolorspace code to avoid repeatedly setting the same color space.
7293 
        The steps that lead to the error are the following:
7294 
 
7295 
          1. The job sets a CIEBasedABC color space as the current color
7296 
             space. The white and black point information from the color
7297 
             space dictionary is combined with the white and black point
7298 
             information in the color rendering dictionary to sample the
7299 
             TransformPQR procedures in that dictionary. The resulting
7300 
             data is placed in the joint CIE cache. All of this activity
7301 
             ends with an execution of the internal operator cie_tpqr_finish
7302 
             (zcrd.c). This operator has two side-effects:
7303 
 
7304 
                 The TransformPQR data structure in the cie_render structure
7305 
                 of the current state is set to TransformPQR_from_cache, which
7306 
                 indicates that the PQR phase of the CIE color mapping (the
7307 
                 white point point adjustment) is to be done via the joint CIE
7308 
                 cache.
7309 
 
7310 
                 The gs_cie_cs_complete procedure is invoked with the "init"
7311 
                 argument set to false, indicating that no further
7312 
                 initialization is required for the joint CIE caches. This
7313 
                 causes the status flag in those caches to be set to
7314 
                 CIE_JC_STATUS_INITED, indicating that the caches are ready
7315 
                 to use.
7316 
 
7317 
          2. The job calls gsave. Since the joint CIE caches can be shared by
7318 
             multiple graphic states, the cache reference count is incremented.
7319 
 
7320 
          3. The job sets a pattern color space, whose base color space is the
7321 
             current (CIEBasedABC) color space.
7322 
 
7323 
             The PostScript interpreter in Ghostscript uses the convention that
7324 
             a base or alternative color space will always be set as the current
7325 
             color space immediately before the enclosing color space is set.
7326 
             The cs_install procedure for the pattern color space
7327 
             (lib/gs_patrn.ps) invokes setcolorspace on the base space. Because
7328 
             this is already the current color space, nothing happens.
7329 
 
7330 
          4. Immediately afterwards, the cs_install procedure invokes the
7331 
             .setpatternspace operator on the enclosing pattern color space.
7332 
             Through a couple of layers, this will invoke the "install_cspace"
7333 
             method for pattern color spaces, the gx_install_Pattern
7334 
             (gspcolor.c). This will in turn invoke the "install_cspace" method
7335 
             for the base color space, in this case gx_install_CIE.
7336 
 
7337 
          5. Through a few additional layers, gx_install_CIE will also call
7338 
             gs_cie_cs_complete (see (1) above), but this time the "init"
7339 
             variable will be set to true, indicating that additional
7340 
             initialization is required.
7341 
 
7342 
             gs_cie_cs_complete will invoke gx_currentciecaches, whose purpose
7343 
             is to make sure that new copies of the joint CIE cache is created
7344 
             when necessary. Since the reference count on the existing cache is
7345 
             larger than 1 (see (2) above), a unique copy of the cache is created
7346 
             and is marked as invalid.
7347 
 
7348 
          6. Subsequently, when drawing is attempted in the base color (the
7349 
             pattern has PaintType 2), the code will note that the cache is
7350 
             not yet valid and invoke cie_joint_caches_init (gscie.c). This
7351 
             routine can do nothing, however, because the TransformPQR structure
7352 
             for the cie_render structure in the graphic state is set to
7353 
             TransformPQR_from_cache, indicating that the only data available
7354 
             for the TransformPQR procedure is in the (now invalidated) cache.
7355 
 
7356 
             As a fall-back, the CIE color is mapped to RGB by setting all
7357 
             components to 0, which yields the black output.
7358 
 
7359 
        The proper fix for this problem is re-designing both the CIE color space
7360 
        and the color rendering structures so that they retain enough information
7361 
        to regenerate the joint CIE cache when necessary. Since that is a big
7362 
        change, the attached modifications take the more modest approach of adding
7363 
        a "forcesetcolorspace" operator, which will set a color space even if it
7364 
        is identical to the current color space.
7365 
 
7366 
        Also included in the set of changes is a minor modification to gs_rectfill
7367 
        (gsdps1.c) that suppresses direct access to the device's fill_rectangle
7368 
        procedure if both overprint and overprint mode are true. Since
7369 
        overprintmode must be applied prior to halftoning, the code must be forced
7370 
        through one of the higher-level methods which include the pre-halftoned
7371 
        device color information.
7372 
 
7373 
        Modified files:
7374 
 
7375 
          lib/gs_cspace.ps
7376 
            Added the _setcolorspace procedure, which accepts both a boolean and
7377 
            a color space dictionary. If the boolean is true, the color space
7378 
            will not be set if it is the same as the current color space (via a
7379 
            conservative evaluation).
7380 
 
7381 
            The setcolorspace pseudo-operator now invokes _setcolorspace with the
7382 
            boolean operand set to true. A new operator, forcesetcolorspace,
7383 
            invokes _setcolorspace with boolean set to false.
7384 
 
7385 
          lib/gs_devn.ps
7386 
          lib/gs_icc.ps
7387 
          lib/gs_indxd.ps
7388 
          lib/gs_patrn.ps
7389 
          lib/gs_sepr.ps
7390 
            Replaced setcolorspace with forcesetcolorspace when setting a base or
7391 
            alternative color space. This is necessary due to some problems in the
7392 
            handling of the the joint CIE cache in the graphic library.
7393 
 
7394 
          src/gsdps1.c
7395 
            Modify gs_rectfill to suppress direct access of a device's
7396 
            fill_rectangle method if both overprint and overprint mode are set
7397 
            to true. This is required to make sure the overprint compositor has
7398 
            access to pre-halftoned device color information with which to
7399 
            implement overprint mode.

        * gs_ll3.ps [1.4] (+5 -1):
7436 
        Modified Files:
7437 
 
7438 
          lib/gs_ll3.ps
7439 
            Added code to create the setoverprintmode and currentoverprintmode
7440 
            operators.
7441 
 
7442 
          src/gconf.c
7443 
            Add the gx_compositor_list array, to list the set of compositor
7444 
            types compiled into the system. Also provided the gs_find_compositor
7445 
            procedure, to locate a compositor method vector based on its
7446 
            type identifier.
7447 
 
7448 
          src/gdevdgbr.c
7449 
            Fixed several bugs in gx_get_bits_copy, for cases in which the
7450 
            transfer of output data involves a skew (bit shift) but no color
7451 
            conversion (a case that is apparently used only by the overprint
7452 
            facility). This case uses the copy_mono method for the 1-bit
7453 
            memory device. The invocation of this method had two problems:
7454 
 
7455 
              1. The temporary device created for the transfer had uninitialized
7456 
                 width and height fields. Because copy_mono will invoke the
7457 
                 fit_copy macro, these fields must be set to reasonable values.
7458 
 
7459 
              2. The width passed to copy_mono must be bit-width, as the
7460 
                 method for a depth == 1 device is used. Previously, the
7461 
                 pixel width was used.
7462 
 
7463 
          src/gdevx.c
7464 
            Fixed a problem in x_copy_image. If the image passed to this routine
7465 
            contains more than one pixel, the colors_and and colors_or fields were
7466 
            not updated. Because these fields are only used for optimization, and
7467 
            properly updating them in this situation is potentially expensive,
7468 
            they are now just set to safe values (colors_and = 0;
7469 
            colors_or = (x_pixel)(-1)).
7470 
 
7471 
          src/genconf.c
7472 
            Added to "-comp" option to support construction of a list of
7473 
            compositors compiled into the system.
7474 
 
7475 
          src/gs.mak
7476 
            Added the SETCOMP and ADDCOMP macros, to provide access to the
7477 
            -comp option of genconf.c.
7478 
 
7479 
          src/gsalphac.c
7480 
            Exported the gs_composite_alpha_type structure, and added a compositor
7481 
            type identifier to this structure. Also modified the de-serialization
7482 
            (read) method for this size so that the data string provided be large
7483 
            enough but not necessarily exactly the right size, and to return the
7484 
            number of bytes actually read (or an error code).
7485 
 
7486 
          src/gscdefs.h
7487 
            Added a prototye for gs_find_compositor (see gconf.c above).
7488 
 
7489 
          src/gscolor.c
7490 
            Modified gx_set_device_color_1 to turn off overprint (and overprint
7491 
            mode).
7492 
 
7493 
          src/gsovc.c:
7494 
            1. Modified the de-serialization method (read) to return the number of
7495 
               bytes actually read (or an error code).
7496 
            2. Renamed gs_overprint_type to be gs_composite_overprint_type, so as
7497 
               to conform to the new convention for compositor names.
7498 
            3. For the overprint devices, set the get_xfont_procs, get_xfont_device,
7499 
               and text_begin methods to use the corresponding default methods,
7500 
               rather than the forwarding methods. Device-supported fonts are
7501 
               incompatible with overprint, as the required low-level calls may
7502 
               not be made. While the text_begin method is not itself a rendering
7503 
               method, it does record an imaging device, and this device must
7504 
               be the overprint device rather than the target device. If the
7505 
               forwarding text_begin method is used, the recorded imaging device
7506 
               would be the target device.
7507 
            4. Modified update_overprint_params to avoid use of the overprint
7508 
               devices for cases in which overprint is true, but all color
7509 
               components are to be drawn. Though the output is not changed, use
7510 
               of the non-overprint device improves performance in this case.
7511 
            5. Modified the default overprint compositor creation method
7512 
               (c_overprint_create_default_compositor) to ignore overprint
7513 
               requests if the current color model has only a single component.
7514 
               Overprinting can never have an effect in this situation, and
7515 
               avoiding these cases also avoids difficulties with mask caching
7516 
               devices (such as are used with the character cache).
7517 
 
7518 
          src/gsstate.c
7519 
            Modified gs_state_update_overprint to update the color model mapping
7520 
            procedures and unset the device color. Though updating the overprint
7521 
            status will never change the color model, the overprint devices
7522 
            require a special set of forwarding color model mapping procedures.
7523 
 
7524 
          src/gxclimag.c
7525 
            Implemented the clist_create_compositor procedure (the create_compositor
7526 
            method for the command list device).
7527 
 
7528 
          src/gxclpath.c
7529 
            Replaced the cmd_opv_put_params code (0xdf) with cmd_opv_extend. This
7530 
            code indicates that the subsequent byte should be read and interpreted
7531 
            as a command from the gx_cmd_ext_op enumeration. Currently, this
7532 
            enumeration has two elements, cmd_opv_ext_put_params (the put_params
7533 
            method) and cmd_opv_ext_create_compositor (the create_compositor
7534 
            method).
7535 
 
7536 
          src/gxclrast.c
7537 
            1. Made the code parsing changes required by the new cmp_opv_extend
7538 
               code (see gxclpath.h above).
7539 
            2. Added the read_create_compositor procedure, to interpret the
7540 
               cmd_opv_ext_create_compositor command.
7541 
 
7542 
          src/gxclutil.c
7543 
            Modified cmd_put_params for the new cmp_opv_extend/cmd_opv_ext_put_params
7544 
            coding techinque.
7545 
 
7546 
          src/gxcmap.c
7547 
            Modified gx_set_cmap_procs to handle devices that have no
7548 
            get_color_mapping_procs method (such as mask caching devices).
7549 
 
7550 
          src/gxcomp.h
7551 
            Added the comp_id field to the gs_composite_type_t structure. Also
7552 
            added macros for the alpha and overprint compositors (the only two
7553 
            compositors in the current system).
7554 
 
7555 
          src/gxoprect.c
7556 
            Fixed typo in pack_scanline_lt8: the source data pointer was not
7557 
            being advanced.
7558 
 
7559 
          src/gxoprect.h
7560 
            Fixed typo in RCS identifier comment.
7561 
 
7562 
          src/lib.mak
7563 
            1. Updated several dependency lists.
7564 
            2. Added code to generate the list of compiled compositors.

7569 
        * gs_setpd.ps [1.5] (+5 -2), gs_init.ps [1.5] (+8 -3):
7570 
        code set from ORIMP to enable overprint and overprint mode.
7571 
 
7572 
        New Files:
7573 
 
7574 
          src/gxoprect.c
7575 
          src/gxoprect.h
7576 
            These files provide the low-level code for the fill_rectangle method
7577 
            of the overprint compositor device. There are three such procedures,
7578 
            which are used in different circumstances:
7579 
 
7580 
              gx_overprint_generic_fill_rectangle is always applicable, but is
7581 
                very slow as it must decode and re-encode the color for each pixel.
7582 
 
7583 
              gx_overprint_sep_fill_rectangle_1 is applicable to separable and
7584 
                linear color encodings whose depth is a divisor of
7585 
                8 * sizeof(mono_fill_chunk) = 32. This is always the
7586 
                case if depth &lt;= 8. The code used in this case is, once past a
7587 
                large amount of setup, about as fast as can be achieved while
7588 
                using get_bits_rectangle.
7589 
 
7590 
              gx_overprint_sep_fill_rectangle_2 is applicable to all other
7591 
                separable and linear color encodings (all of which will have
7592 
                depth % 8 = 0). This uses a byte-wise method which is in principle
7593 
                slower than what could be achieved with a chunk-wise method, but
7594 
                is much easier to code in the general case (i.e.: for multiple
7595 
                possible depths). It will likely be faster in practice.
7596 
 
7597 
        Modified Files:
7598 
 
7599 
          lib/gs_init.ps
7600 
          lib/gs_setpd.ps
7601 
            Modified erasepage (and several other bits of code that erase the
7602 
            page) to turn off overprint before filling the page. This is necessary
7603 
            to preserve the meaning of erasepage.
7604 
 
7605 
          src/gsbitops.c
7606 
          src/gsbitops.h
7607 
            Added the bits_fill_rectangle_masked procedure, a generalization of
7608 
            the bits_fill_rectangle procedure that allows for a component mask.
7609 
            Also generalized bits_fill_rectangle (and bits_fill_rectangle_masked)
7610 
            to support depth &gt; 8, so long as
7611 
            (8 * sizeof(mono_fill_chunk)) % depth = 0.
7612 
 
7613 
            Currently, bits_fill_rectangle_masked is used only by the overprint
7614 
            compositor device, but it can also be used by devices that can
7615 
            directly implement overprint (such as the memory device).
7616 
 
7617 
          src/gscdevn.c
7618 
            Modified check_DeviceN_component_names to initialize the
7619 
            component_map.sep_type field of the imager state to SEP_OTHER.
7620 
            Previously this field was not set for DeviceN color spaces, which
7621 
            confused some of the overprint code.
7622 
 
7623 
          src/gsovrc.c
7624 
            Implemented the real overprint_fill_rectangle procedures. As part of
7625 
            this work, added the local procedure swap_color_index, that swaps
7626 
            bytes in a color index as required to work with byte-oriented bitmaps
7627 
            on little-endian devices (only if depth &gt; 8).
7628 
 
7629 
            Also fixed a parity bug in the creation of the retain_mask.
7630 
 
7631 
          src/gsovrc.h
7632 
            Fixed typo (/* $Id: History7.htm,v 1.44 2005/10/20 19:46:23 ray Exp $Id: History7.htm,v 1.44 2005/10/20 19:46:23 ray Exp $ */).
7633 
 
7634 
          src/gxdcconv.c
7635 
            Modified color_rgb_to_cmyk to work if the imager state pointer
7636 
            operand is a null pointer. Note that in this case full undercolor
7637 
            removal and black generation will be performed, which is consistent
7638 
            with other such conversions in the code that do not have access to
7639 
            the imager state, but differs from the mapping used if the imager
7640 
            state is available but has no blackgeneration or undercolor removal
7641 
            map.
7642 
 
7643 
          src/lib.mak
7644 
            Added the gxoprect.$(OBJ) target and included this as a dependency
7645 
            in LIB4s. Also updated some other dependency lists.
7646 
 
7647 
 
7648 
        Additional file modified (not for overprint but needed for release):
7649 
 
7650 
          src/gdevdflt.c
7651 
            Added code to select a reasonable default value for the decode_color
7652 
            method, as this method is used extensively by the generic overprint
7653 
            implementation routines. The modifications are just a first pass to
7654 
            allow us to test the overprint code; they are not intended as a
7655 
            final solution.

7670 
         Modified files:
7671 
 
7672 
          gsstate.c
7673 
            Added code to ignore an error return from the create_compositor call
7674 
            in gs_state_update_overprint if the call was made to turn off
7675 
            overprint. This avoids errors for device configurations that do not
7676 
            (yet) support the create_compositor call, when running files that do
7677 
            not require overprint support.
7678 
 
7679 
          gsovrc.h
7680 
            Fixed a typo in a commment.
7681 
 
7682 
          gxclrast.c
7683 
            Fixed a re-entrancy problem in read_set_color_space that was introduced
7684 
            by the previous modification to this file.
7685 
 
7686 
          gsimage.c
7687 
            Added a comment concerning re-entrancy, and slightly modified another
7688 
            comment.
7689 
 
7690 
          gscspace.c
7691 
            Added some comments concerning re-entrancy.

7698 
            Added full compositor device "plumbing". The overprint compositor
7699 
            now does all of the required device creation and setup work. The
7700 
            only piece still missing are implementations of the low-level
7701 
            rendering routines that actually implement overprint.

          src/gxht.c
7709 
          src/gxpcolor.h
7710 
            Added the method get_nonzero_comps to the gx_device_color_type_t
7711 
            structure (the gx_device_color methods). This method is used by
7712 
            the overprint code to determine which color component intensities
7713 
            have non-zero value, which must be known to implement overprint
7714 
            mode.
7715 
 
7716 
          src/gsovrc.h
7717 
          src/gscspace.c
7718 
            Changed the drawn_comps field of the gs_overprint_params_t
7719 
            structure from a byte array to a gx_color_index. This is a bit
7720 
            ugly, as the value is a bit map rather than an encoded color,
7721 
            but allows much simpler processing. (As in device colors, a
7722 
            gx_color_index is used because it is known to be large enough.
7723 
 
7724 
          src/lib.mak
7725 
            Updated dependency list for gsovrc.$(OBJ).

            Implementation of the overprint compositor. For the moment, this is

            Interface to the overprint compositor. This is in essentially final
7738 
            form, even though only a stub implementation of the compositor is
7739 
            available. This file also includes a lengthy comment describing when
7740 
            the compositor must be updated.

7755 
            Incorporated an optimization of setcolorspace from the casper head.
7756 
            The optimization avoids setting the color space if it is the same as
7757 
            the current color space. gs_icc.ps also contains a fix for a bug
7758 
            in the handling of DataSources that are streams (rather than strings;
7759 
            Dan discovered and analyzed this bug).
7760 
 
7761 
            Note that this is a fairly complex optimization, and there were many
7762 
            problems with the head code that needed to be resolved. Among these
7763 
            were:
7764 
 
7765 
              1. An invocation of setcolorspace should always set the default
7766 
                 color for the operand color space, even if that color space is
7767 
                 identical to the current color space.
7768 
 
7769 
              2. If UseCIEColor is true, setcolorspace must be executed if
7770 
                 the operand color space involves device-specific color spaces.
7771 
                 This is because the Default{Gray,RGB,CMYK} instances of the
7772 
                 ColorSpace resource category may have changed.
7773 
 
7774 
              3. When UseCIEColor is changed from true to false in setpagedevcie,
7775 
                 the implicit initgraphics invocation must perform a setcolorspace
7776 
                 operation, even if the current color space is DeviceGray. This
7777 
                 is necessary to ensure that the un-substituted DeviceGray color
7778 
                 space is set as the current color space.
7779 
 
7780 
 
7781 
          lib/gs_init.ps
7782 
            In /showpage, replace the sequence "erasepage ... initgraphics" with
7783 
            "initgraphics 1 setcolor .fillpage 0 setcolor". This has the desired
7784 
            effect, and avoids two unnecessay invocations of setcolorspace.
7785 
 
7786 
 
7787 
          lib/gs_setpd.ps
7788 
            1. Modified the currentpagedevice pseudo-operator for cases in which
7789 
               the stored page device must be copied. Previously, the new copy
7790 
               was allocated in the current VM mode, which could cause
7791 
               invalidaccess errors if currentpagedevice was invoked while in
7792 
               global VM mode and composite objects stored in the page device
7793 
               dictionary were in local VM (this problem is present in the PS3
7794 
               FTS). The new code will allocate the copy in the save VM as the
7795 
               original dictionary.
7796 
 
7797 
            2. In setpagedevice, added code to set current color space to
7798 
               something other than DeviceGray if modification of the page device
7799 
               will set UseCIEColor to false. This is necessary for the
7800 
               setcolorspace optimization to function properly (see above).
7801 
 
7802 
            3. In the .postinstall pseudo-operator, replaced "erasepage initgraphics"
7803 
               with "initgraphics 1 setcolor .fillpage 0 setcolor". This avoids
7804 
               two unnecessary invocations of setcolorspace.
7805 
 
7806 
 
7807 
          src/gdevp14.c
7808 
            Added the pdf14_create_compositor method. This method will check if
7809 
            the compositor to be created is the overprint compositor. If so,
7810 
            the request to create the compositor will simply be ignored, as
7811 
            the gs_pdf14_device and its associated marking device must implement
7812 
            overprint directly.
7813 
 
7814 
 
7815 
          src/gscdevn.c
7816 
            1. Removed the equality check method.
7817 
 
7818 
            2. Added the set_overprint method for DeviceN color spaces.
7819 
 
7820 
 
7821 
          src/gscolor2.c
7822 
            1. Removed the equality check method.
7823 
 
7824 
            2. Added the set_overprint method for Indexed color spaces.
7825 
 
7826 
 
7827 
          src/gscpixel.c
7828 
            1. Removed the equality check method.
7829 
 
7830 
            2. Added the set_overprint method for DevicePixel color spaces.
7831 
 
7832 
 
7833 
          src/gscscie.c
7834 
            1. Removed the equality check method.
7835 
 
7836 
            2. Added the set_overprint method for CIEBased color spaces.
7837 
 
7838 
 
7839 
          src/gscsepr.c
7840 
            1. Removed the equality check method.
7841 
 
7842 
            2. Added the set_overprint method for Separation color spaces.
7843 
 
7844 
            3. Moved the gs_{set|current}overprint[mode] procedures to gsstate.c.
7845 
 
7846 
 
7847 
          src/gscsepr.h
7848 
            Moved prototypes for the gs_{set|current}overprint[mode] procedures
7849 
            to gsstate.h.
7850 
 
7851 
 
7852 
          src/gscspace.c
7853 
            1. Removed the color space equality check methods for the device-
7854 
               specific color spaces.
7855 
 
7856 
            2. Added the basic set_overprint procedures, to provide color-space
7857 
               specific setting of the overprint compositor.
7858 
 
7859 
            3. Modified the gs_cspace_{build|init}_Device{Gray|RGB|CMYK}
7860 
               procedures to use the same identifier for all instances of
7861 
               the parameterless color spaces (i.e.: all DeviceGray instances
7862 
               will have the same id, as will all DeviceRGB instances, but the
7863 
               id for any DeviceGray will differ from the id for a DeviceRGB
7864 
               instance). This enables an optimization in the gs_setcolorspace
7865 
               routine that had been lost in the previous code modification.
7866 
 
7867 
 
7868 
          src/gscspace.h
7869 
            Removed prototype for the gs_color_space_equal procedure.
7870 
 
7871 
 
7872 
          src/gsicc.c
7873 
            1. Removed the equality check method.
7874 
 
7875 
            2. Added the set_overprint method for ICCBased color spaces.
7876 
 
7877 
 
7878 
          src/gslib.c
7879 
            Modified test9 to explicitly reset the current color space; this
7880 
            is no longer done by gs_initgraphics.
7881 
 
7882 
 
7883 
          src/gspcolor.c
7884 
            Added set_overprint method for pattern color spaces, removed the
7885 
            equality check method.
7886 
 
7887 
 
7888 
          src/gsstate.c
7889 
            1. Added code to update the overprint compositor when the current
7890 
               color space, current device, overprint, or overprint mode
7891 
               settings change. Included in this change is code in gs_grestore_only
7892 
               that updates the overprint compositor as part of the grestore
7893 
               operation when this is required.
7894 
 
7895 
            2. Moved the gs_{set|current}overprint[mode] procedures to this file
7896 
               from gscsepr.c. This is more convenient for the new code, and
7897 
               gscsepr.c was never a particularly appropriate place for these
7898 
               routines.
7899 
 
7900 
            3. Modified gs_initgraphics to not reset the current color space or
7901 
               current color. For PostScript this must now be done in the
7902 
               PostScript code to properly handle color space substitution.
7903 
               Other clients that use this procedure (the XL interpreter is the
7904 
               only one (aside from gslib.c)) can easily reset these parameters
7905 
               as well.
7906 
 
7907 
 
7908 
          src/gsstate.h
7909 
            Moved prototypes for the gs_{set|current}overprint[mode] procedures
7910 
            here from gscsepr.h.
7911 
 
7912 
 
7913 
          src/gxccache.c
7914 
            Modified gx_image_cached_char to just return if the current color
7915 
            is a pure gx_no_color_index (transparent).
7916 
 
7917 
 
7918 
          src/gxcspace.h
7919 
            1. Removed the equality check method.
7920 
 
7921 
            2. Added the set_overprint method.
7922 
 
7923 
 
7924 
          src/gxipixel.c
7925 
            Modified the gx_image_enum_begin to allow the Decode array for
7926 
            imagemasks to have any two distinct numbers, rather than just 0 and
7927 
            1. This matches the behavior of all Adobe systems (though not the
7928 
            documentation), and avoids some spurious failures when running the
7929 
            FTS.

            Modified pattern_accum_copy_mono to just return if both the foreground
7934 
            and background colors are gx_no_color_index (transparent). If this is
7935 
            not done, the mask device's copy_mono procedure may generate an
7936 
            error when invoked (this is true for mem_mono_copy_mono).
7937 
 
7938 
 
7939 
          src/iutil.c
7940 
            Modified obj_eq to consider two 0-length arrays to be equal,
7941 
            irrespective of their type and their pointers (the latter aren't
7942 
            meaningful if the array length is 0). This matches the PostScript
7943 
            documentation and the behavior of Adobe systems. It also fixes
7944 
            some spurious failures in the FTS.
7945 
 
7946 
 
7947 
          src/lib.mak
7948 
            Added an entry for gsovrc (the overprint compositor), and updated
7949 
            various dependency lists.
7950 
 
7951 
 
7952 
          src/zfdcte.c
7953 
            Modified the DCTEncode procedure (zDCTE) to allocate the
7954 
            jpeg_compress_data and subsidiary memory structures in current VM.
7955 
            Previously these structures were allocated in gs_default_memory,
7956 
            which does not support garbage collection. Since the structures
7957 
            were subject to garbage collection and relocation, chaos could
7958 
            and, in the case of FTS file 119-28.ps, did ensue.
7959 
 
7960 
            Note that these structure must be allocated immovable, which
7961 
            requires a considerable amount of overhead when using VM. A better
7962 
            approach would be to allocate them in gs_default_memory, and use
7963 
            a more sophisticated structure descriptor for the stream_DCT_state
7964 
            structure (st_DCT_state).
7965 
 
7966 
 
7967 
          src/zgstate.c
7968 
            Slightly simplified zinitgraphics, and updated a comment in this
7969 
            procedure.
7970 
 
7971 
 
7972 
          src/zmisc.c
7973 
            Modified realtime operator to set a zero point at boot time. This
7974 
            avoids an annoying delay in running FTS panel 211-01 (206-01.ps).
7975 
 
7976 
 
7977 
          zpcolor.c
7978 
            Modified the pattern_paint_prepare procedure to use gs_setdevice_no_int
7979 
            rather than gx_set_device_only. It is not clear why the latter
7980 
            procedure was ever used in this location, and it is now important to
7981 
            use the former procedure so the overprint compositor may be properly
7982 
            updated.

        Overprint implementation (Jan Stoeckenius)
7995 
 
7996 
        This is a preliminary code release for the overprint capability. The
7997 
        release does not contain the overprint facility itself; it consists
7998 
        entirely of modifications so that color space changes will occur in a
7999 
        predictable fashion.

8010 
        Files added:
8011 
 
8012 
          lib/gs_cspace.ps      PostScript portion of the basic color space handling;
8013 
                                see the extensive comment at the head of the file
8014 
                                for information. Note that color space substitution
8015 
                                and the hue-saturation-brightness (HSB) color space
8016 
                                are now fully implemented in the PostScript code;
8017 
                                the interpreter and the graphic library are no longer
8018 
                                involved in or even aware of these features.
8019 
 
8020 
          lib/gs_devcs.ps       Implementation of the DeviceGray, DeviceRGB, and
8021 
                                DeviceCMYK color spaces.
8022 
 
8023 
          lib/gs_ciecs2.ps      Implementation of the LangaugeLevel 2 CIEBased color
8024 
                                spaces: CIEBasedA and CIEBasedABC.
8025 
 
8026 
          lib/gs_ciecs3.ps      Implementation of the LanguageLevel 3 CIEBased color
8027 
                                spaces: CIEBasedDEF and CIEBasedDEFG
8028 
 
8029 
          lib/gs_devpxl.ps      Implementation of the DevicePixel color spaces
8030 
 
8031 
          lib/gs_indxd.ps       Implementation of the Indexed color space.
8032 
 
8033 
          lib/gs_sepr.ps        Implementaton of the Separation color space.
8034 
 
8035 
          lib/gs_devn.ps        Implementation of the DeviceN color space.
8036 
 
8037 
          lib/gs_patrn.ps       Implementation of the Pattern color space.
8038 
 
8039 
 
8040 
          lib/gs_img.ps         Implementation of the traditional (non-dictionary)
8041 
                                form of the image and imagemask operators, and the
8042 
                                colorimage operator (including the Next alphaimage
8043 
                                facility). The interpreter now provides only the
8044 
                                dictionary form of the image and imagemask operators,
8045 
                                including a variation that provides alpha-channel
8046 
                                support.
8047 
 
8048 
                                Also modified the handling of color spaces for
8049 
                                ImageType 2 images. This slightly changes the behavior
8050 
                                of these images. If PixelCopy is defined to be true
8051 
                                in the image dictionary but such a copy cannot be
8052 
                                supported, an error will be generated. This is in
8053 
                                agreement with Adobe's documentation, but differs
8054 
                                from the earlier behavior.
8055 
 
8056 
          The code for Indexed, Separation, and DeviceN color spaces
8057 
          incorporates code, courtesy of Dan, that will invoke the lookup or
8058 
          tint transform procedure in the appropriate context if this is
8059 
          appropriate (if there is a lookup procedure for Indexed color spaces
8060 
          or the alternate color space is in use for Separation and DeviceN
8061 
          color spaces). Currently this is not done recursively (if an Indexed
8062 
          color space has a DeviceN base color space, for example), but that
8063 
          has not proven necessary in practice. If necessary, it can be added.
8064 
 
8065 
 
8066 
          src/zcolor3.c         Code to implement the .setuseciecolor operator. This
8067 
                                operator is used only in the setpagedevice code, and
8068 
                                makes certain that the use_cie_color field in the
8069 
                                interpreter's graphic state mirrors the setting of
8070 
                                the UseCIEColor page device parameter.
8071 
 
8072 
 
8073 
        Files modified:
8074 
 
8075 
          lib/gs_dpnxt.ps       Added PostScript implementation of the alphaimage
8076 
                                operator. This uses the internal .alphaimage
8077 
                                operator, which is a variation of the image
8078 
                                operator that provide alpha-channel support.
8079 
 
8080 
          lib/gs_icc.ps         Rewritten to implement the ICCBased color space
8081 
                                in the new scheme. See the comments in
8082 
                                lib/gs_cspace.ps for information.
8083 
 
8084 
          lib/gs_init.ps        Modified to include gs_cspace.ps, gs_devcs.ps,
8085 
                                and gs_img.ps, and to remove img_util_dict and
8086 
                                .cspace_util_dict from userdict at the end of
8087 
                                initialization.
8088 
 
8089 
          lib/gs_lev2.ps        All explicit color spaces removed (with one
8090 
                                exception, and replaced by inclusion of gs_devpxl.ps,
8091 
                                gs_ciecs2.ps, gs_indxd.ps, gs_sepr.ps, and
8092 
                                gs_patrn.ps. The only remaining color space support
8093 
                                feature is moving the setcolorspace and setcolor
8094 
                                pseudo-operators, and the colorspacedict dictionary,
8095 
                                to level2dict. This must be done here, as it is not
8096 
                                known that level2dict exists when gs_cspace.ps is
8097 
                                first run.
8098 
 
8099 
                                Also removed all explicit image support. This is
8100 
                                now handled by gs_img.ps (see above).
8101 
 
8102 
          lib/gs_ll3.ps         Removed the old support for color space substitution;
8103 
                                this is now handled directly by the color space
8104 
                                code (see the comments in gs_cspace.ps for
8105 
                                information). Added inclusion of gs_ciecs3.ps and
8106 
                                gs_devn.ps.
8107 
 
8108 
          lib/gs_setpd.ps       Added support for the .getuseciecolor and
8109 
                                .setuseciecolor operators. This maintains a
8110 
                                "mirror" of the UseCIEColor parameter in the
8111 
                                graphic state, to allow fast access.
8112 
 
8113 
          src/gdevnfwd.c        In gx_forward_get_color_mapping_procs, added a check
8114 
                                for the case of a target device which has no
8115 
                                get_color_mapping_procs procedure. This led to a
8116 
                                segmentation violation crash for FTS file 296-01.ps
8117 
                                The fix may not be the correct one, as we are not
8118 
                                certain why a device would lack this method.
8119 
 
8120 
          src/gdevp14.c         Replaced a use of the shared field in the graphic state
8121 
                                with a color space allocated on the C-language stack.
8122 
 
8123 
          src/gdevpsdi.c        Replaced an instance of use of the gs_cspace_DeviceRGB
8124 
                                procedure.
8125 
 
8126 
          src/gscolor.c         Removed gs_currentgray and gs_currentrgbcolor. Modified
8127 
                                gs_setgray and gs_setrgbcolor to use gs_setcolorspace
8128 
                                and gs_setcolor. This eliminates use of the
8129 
                                gs_current_Device*_space routines.
8130 
 
8131 
          src/gscolor.h         Removed prototypes for gs_currentgray and
8132 
                                gs_currentrgbcolor.
8133 
 
8134 
          src/gscolor1.c        Removed gs_currentcmykcolor. Modified gs_setcmykcolor
8135 
                                to use gs_setgray and gs_setcolorspace.
8136 
 
8137 
          src/gscolor1.h        Removed prototype for gs_currentcmykcolor.
8138 
 
8139 
          src/gscolor2.c        Removed gs_currentcolorspace_index. Removed the color
8140 
                                index tracking used as part of the color space
8141 
                                substitution method.
8142 
 
8143 
          src/gscolor2.h        Removed prototype for gs_currentcolorspace_index.
8144 
 
8145 
          src/gscscie.c         Eliminated use of the gs_cspace_Device* routines.
8146 
 
8147 
          src/gscsepr.c         Fixed a pair of typos in revision 1.6 of the code.
8148 
                                In gs_cspace_set_sepr_proc and
8149 
                                gx_concretize_Separation, the code was still accessing
8150 
                                pcspace-&gt;params.device_n when it wanted to access
8151 
                                pcspace-&gt;params.separation. This caused a crash in
8152 
                                FTS file 245-01.ps.
8153 
 
8154 
          src/gscspace.c        Removed gs_cspace_Device* procedures.
8155 
 
8156 
          src/gscspace.h        Removed prototypes for gs_cspace_Device* procedures.
8157 
 
8158 
          src/gsimage.c         Removed use of the gs_cspace_DeviceGray procedure.
8159 
 
8160 
          src/gsiparam.h        Removed the gs_image_t_int_{gray, rgb, cmyk} macros.
8161 
 
8162 
          src/gsistate.c        Updated code to reflect removal of the shared field in
8163 
                                the imager state. As part of this, the
8164 
                                rc_free_imager_shared and gx_device_color_spaces_free
8165 
                                procedures were removed.
8166 
 
8167 
          src/gslib.c           Removed use of the gs_current_Device*_space and
8168 
                                gs_image_t_init_gray procedures.
8169 
 
8170 
          src/gspcolor.c        Removed reference to the orig_cspace_index field,
8171 
                                which is no longer part of the library's graphic
8172 
                                state.
8173 
 
8174 
          src/gsptype1.c        Eliminated use of the gs_cspace_DeviceGray procedure,
8175 
                                and insured that a color space is set as the current
8176 
                                color space before it is used.
8177 
 
8178 
          src/gsstate.c         Removed code that maintained the device_color_spaces
8179 
                                field (color space substitution), which is no longer
8180 
                                in the library's graphic state.
8181 
 
8182 
          src/gxclrast.c        Removed use of the gs_cspace_Device* procedures.
8183 
 
8184 
          src/gximage3x.c       Removed use of the gs_image_t_init_gray procedure.
8185 
 
8186 
          src/gximage2.c        Modified color space handling for ImageType 2 images.
8187 
                                Note that there was and still is a problem with the
8188 
                                handling of transformations in this code.
8189 
 
8190 
          src/gxistate.h        Removed the shared field of the imager state, all
8191 
                                associated structures and prototypes, and modified
8192 
                                the affected GC macros. The gx_device_color_spaces_t
8193 
                                structure was previously used in the graphic library's
8194 
                                state as well, but that use has been eliminated.
8195 
 
8196 
          src/gzstate.h         Removed the the device_color_spaces field, and modified
8197 
                                the requisite GC macros
8198 
 
8199 
          src/idparam.c         Modified dict_float_array_check_param to handle
8200 
                                packed (short or mixed) arrays.
8201 
 
8202 
          src/igstate.h         Added the use_cie_color field. This is a mirror for
8203 
                                the UseCIEColor parameter of the page device, used
8204 
                                because the currentpagedevice operator is potentially
8205 
                                expensive.
8206 
 
8207 
          src/iimage.h          Modified to restrict the interpreter to just the
8208 
                                dictionary form of the image and imagemask operator.
8209 
                                This removes the zimage_opaque_setup, zimage_data_setup,
8210 
                                and zimage_multiple prototypes, and moves the
8211 
                                image_params structure and the image1_setup
8212 
                                prototypes to this file (from iimage2.h).
8213 
 
8214 
          src/iimage2.h         Moved everything except the prototype for
8215 
                                process_non_source_image to iimage.h.
8216 
 
8217 
          src/iutil.c           Added process_float_array procedure, to allow packed
8218 
                                (short, mixed) arrays of numbers to be handled.
8219 
 
8220 
          src/iutil.h           Added prototype for the process_float_array procedure.
8221 
 
8222 
          src/zcolor.c          Removed:
8223 
                                  zcurrentgray, zcurrentrgbcolor,
8224 
                                  setgray, setrgbcolor
8225 
                                Moved (from zcolor2.c):
8226 
                                  zcurrentcolor, zcurrentcolorspace,
8227 
                                  zsetcolor, zsetcolorspace
8228 
                                Added:
8229 
                                  zgetuseciecolor   queries the use_cie_color field
8230 
                                                    in the interpreter state
8231 
                                  zsetdevcspace     sets a DeviceGray, DeviceRGB, or
8232 
                                                    DeviceCMYK color space
8233 
 
8234 
          src/zcolor1.c         Removed zcurrentcmykcolor, zsetcmykcolor, and
8235 
                                zcolorimage.
8236 
 
8237 
          src/zcolor2.c         Removed everything in prior version. Added
8238 
                                zusealternate, to test if an alternate color space
8239 
                                is being used (for a Separation, DeviceN, or ICCBased
8240 
                                color space), or if a base color space is in use
8241 
                                (for an Indexed or a Pattern color space that uses
8242 
                                a base space).
8243 
 
8244 
          src/zdpnext.c         Replace the alphaimage operator with .alphaimage,
8245 
                                which has the semantics of the dictionary form of
8246 
                                the image operator.
8247 
 
8248 
          src/zgstate.c         Modified the initgraphics operator to set the
8249 
                                colorspace.array field to a legitimate color space
8250 
                                (previously it was set to a null object). Also
8251 
                                inserted code to initialize the use_cie_color field
8252 
                                to false.
8253 
 
8254 
          src/zimage.c          Removed the traditional-form image and imagemask
8255 
                                operators (zimage and zimagemask), and moved the
8256 
                                dictionary form of these operators to this file
8257 
                                from zimage2.c. Also, added the has_alpha parameter
8258 
                                to the data_image_params and pixel_image_params
8259 
                                procedures, to support the .alphaimage operator.
8260 
 
8261 
          src/zimage2.c         Moved everything except the process_non_source_image
8262 
                                procedure to zimage.c.
8263 
 
8264 
          src/zimage3.c         Updated calls to data_image_params and
8265 
                                pixel_image_params to add has_alpha parameter.
8266 
 
8267 
          src/zmisc3.c          Removed .setsubstitutecolorspace operator.
8268 
 
8269 
          src/zpcolor.c         Modified .setpatternspace to handle a packed (short,
8270 
                                mixed) array operand.
8271 
 
8272 
          src/zshade.c          Modified build_mesh_shading to handle a packed (short,
8273 
                                mixed) DataSource array operand.
8274 
 
8275 
          src/ztrans.c          Modified calls to data_image_params and
8276 
                                pixel_image_params to add has_alpha operand.
8277 
 
8278 
          src/watclib.mak       Removed reference to the hsblib.dev, which no longer
8279 
                                exists and which, for some unknown reason, was directly
8280 
                                included in this makefile. Does anyone still use this
8281 
                                file?
8282 
 
8283 
          src/int.mak           Removed hsb.dev and the zimage2_l2 operators, added
8284 
                                zcolor3.c, updated various dependency lists.
8285 
 
8286 
          src/lib.mak           Removed hsblib.dev and gscssub.[ch], updated various
8287 
                                dependency lists. Note that this file has not yet
8288 
                                been modified to always compile with Level 3 support.

8482 
 
8483 
<p>
8484 
This release integrates the rewritten pdfwrite font copying code,
8485 
fixing a large class of pdfwrite bugs involving incremental font
8486 
updating. This project was completed before the DeviceN merge was
8487 
ready, so this release (rather than 7.21 as previously stated) is
8488 
the final checkpoint prior to the DeviceN merge.
8489 
 
8490 
<p>
8491 
Overall, pdfwrite is probably an improvement over previous releases,
8492 
but there are still known issues. Testing of pdfwrite with real-world
8493 
files is encouraged.

<p>The nightly regression tests show many changes. However, most of
8588 
the non-pdf regressions are tiny changes resulting in comparing a
8589 
debug build against a non-debug baseline. The rendering really
8590 
shouldn't be different at all, so we're leaving these regressions open
8591 
until we can fix the discrepancy. On the pdfwrite side, most of the
8592 
regressions are actually improvements, but there are some known
8593 
issues.  Notably, the "same_font" function is incorrect, and deriving
8594 
several fonts from a standard font, replacing Metrics or Metrics2
8595 
only, pdfwrite incorrectly merges them into a single font. This causes
8596 
a regression with 093-01.ps and probably other test files.

alternate color space of a DeviceN space was being used, that the procedure
8782 
would run when 'setcolor' was executed and that the stack would be
8783 
accessible during that procedure. This fixes several bug reports with

8848 
This is a reasonably stable development snapshot, the last before the
8849 
DeviceN work gets merged in. In particular, this version is probably
8850 
the most stable pdfwrite version to date.

Fixes problems:
8976 
	- Changes the operation of AutoFilter{Gray,Color}Images to always
8977 
use the lossless filter (normally FlateEncode), rather than using DCTEncode
8978 
for 8-bit-per-component images at least 64x64 in size. While this isn't
8979 
optimal, it fixes a long-standing problem that many users have complained
8980 
about. Fixes SourceForge #450663. (doc/Ps2pdf.htm [1.41]: 2002/04/08
8981 
21:21:23 lpd)
8982 
	- The recently added reference to zcidtest.c had the correct text
8983 
but an incorrect URL. (doc/Develop.htm [1.73]: 2002/04/09 02:03:22 lpd)
8984 
	- the url for the guide to international paper sizes has changed.
8985 
Thanks to Nelson Beebe for finding the update. (doc/Use.htm [1.52]:
8986 
2002/04/14 01:08:14 giles)
8987 
	- The new file md5main.c was not included in the catalog of source
8988 
files. (doc/Develop.htm [1.74]: 2002/04/14 15:56:53 lpd)
8989 
	- More compatibility to Adobe interpreters in 'eexec'. This is
8990 
NON-BACKWARD-COMPATIBLE change. Now eexec skips all whitespaces at the
8991 
beginning of input stream, except for PFBDecode output. Thanks to L. Peter
8992 
Deutsch for participation. Source Forge bug "[ 428891 ] Undefined commands
8993 
interpreting Postscri". (doc/Language.htm [1.49]: 2002/05/01 23:15:23 igor)
8994 
	- pdfwrite relied on the PostScript interpreter to load and make
8995 
available the known encodings and glyph sets identified in src/gsccode.h.
8996 
With this change, pdfwrite can now be used without a PostScript interpreter,
8997 
and with fonts that do not implement the known_encode callback.
8998 
(doc/Develop.htm [1.78], doc/Psfiles.htm [1.32]: 2002/05/12 22:38:08 lpd)
8999 
	- Fixes a typo in, and slightly improves, documentation for invoking
9000 
cvs2hist as part of the release process. Fixes SourceForge #551275.
9001 
(doc/Release.htm [1.61]: 2002/06/26 20:14:45 lpd)
9002 
	- Fixes a typo in the reference to src/gdevpdte.c.
9003 
(doc/Develop.htm [1.83]: 2002/06/27 00:50:23 lpd)
9004 
	- Add the option -dUseCropBox to set the page size from the CropBox
9005 
rather than the MediaBox. This is appropriate when using ghostscript to view
9006 
PDF files or convert to bitmaps. It probably isn't appropriate for printing.
9007 
Fixes SourceForge bugs #522486, "Wromg size EPS generated from PDF" and
9008 
#538267 "Problems with Media Box in PDF and PS interpreter".

9018 
Changes gs_cmap_t (internal representation of CMaps) to an abstract
9019 
superclass with multiple implementations: standard Adobe CMapType 1,
9020 
TrueType 16-bit cmap (Platform 3, Encoding 1, Format 4), and one-for-one.
9021 
Adds the ability to designate a CMap as Unicode-based. Enhances pdfwrite so
9022 
that composite fonts (including those based on TrueType Unicode fonts) with
9023 
Unicode-based CMaps are embedded in the PDF file with the original text
9024 
preserved and with an appropriate ToUnicode CMap, making the text searchable
9025 
in Acrobat. (doc/Develop.htm [1.72]: 2002/04/08 21:02:44 lpd)
9026 
 
9027 
Documents more clearly the fact that the ProcessColorModel parameter for
9028 
ps2pdf / pdfwrite does not affect (most) images. Also changes the "notes"
9029 
references from the parameter table to live links. (doc/Ps2pdf.htm [1.42]:

(doc/Issues.htm [1.23]: 2002/04/09 22:51:20 lpd)
9035 
 
9036 
Add an example using .locksafe to permit reading of files anywhere while
9037 
preventing file writing, deleting or renaming (as with the pre 7.20 SAFER
9038 
mode). Related to SourceForge bug #541856. (doc/Language.htm [1.48]:

9040 
 
9041 
Deletes "Vanilla" functions, which have not been used for a long time. They
9042 
were originally created for implementing FunctionType 4 functions using a
9043 
callback to the PostScript interpreter, but FunctionType 4 functions have
9044 
had their own interpreter since 3/19/2000 (first revision of gsfunc4.c).

9069 
Refactors the pdfwrite driver so that none of the structures, and very few

9071

SF#559565 (doc/Make.htm [1.51]: 2002/06/24 06:20:25 jeong)
9086 
 
9087 
Adds a complete rewrite of the font and text code in pdfwrite, based on
9088 
copying fonts incrementally to stable memory rather than trying to deal with
9089 
fonts being freed at unpredictable times. Should fix a large number of
9090 
current SourceForge bugs when completed: however, the code is currently in
9091 
pre-alpha state and is not usable on any realistic input. The API is
9092 
compatible with the previous pdfwrite text code; the choice of which set to
9093 
use is controlled by a single, documented line in src/devs.mak.

Fixes problems:
9122 
	- gscdef.c must contain a definition for GS_PRODUCT that matches the
9123 
definition used by the baseline. run_nightly now sets GS_PRODUCT to "AFPL
9124 
Ghostscript" correctly regardless of it's setting in the repository.
9125 
(toolbin/tests/run_nightly [1.4]: 2002/04/09 01:25:26 jack)
9126 
	- gscheck_pdfwrite.py was modeled after run_regression instead of
9127 
check_*.py. This corrects the script so that it follows the testing
9128 
conventions and also adds gscheck_all.py which will run every gscheck_*.py
9129 
test (of which currently there is only one).

Cleans up a number of design problems in the font callback procedures: 1)
9333 
Eliminates the gx_xfont_callbacks structure entirely. The known_encode
9334 
procedure is no longer needed: the new facilities in gscencs.[hc] make it
9335 
unnecessary, and none of the three implementors of the xfont interface use
9336 
it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
9337 
change for all clients of the glyph_name and known_encode procedures (of
9338 
which there are, respectively, 11 and 0 in the current code base), and for
9339 
all places that define gs_font_procs structures statically or initialize the
9340 
callbacks dynamically (of which there are currently only two, one in
9341 
gsfont.c and one in zbfont.c). There are also 3 identical places in the
9342 
GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
9343 
minor changes, with a small net reduction in code. 2) Deletes the
9344 
char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
9345 
three current xfont implementations implements it. 3) Changes the
9346 
char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
9347 
callback procedure, it takes a const gs_string * argument that is the actual
9348 
glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
9349 
NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
9350 
(At present, there are 3 implementors, none of which use the glyph_name
9351 
callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
9352 
procedure, which is still required for other purposes, to gs_font_procs,
9353 
changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
9354 
gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
9355 
clients, but they must already change because of item (1) above. 5)

Eliminates the registered_Encodings array in the PostScript interpreter,
9357

Cleans up a number of design problems in the font callback procedures: 1)
9566 
Eliminates the gx_xfont_callbacks structure entirely. The known_encode
9567 
procedure is no longer needed: the new facilities in gscencs.[hc] make it
9568 
unnecessary, and none of the three implementors of the xfont interface use
9569 
it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
9570 
change for all clients of the glyph_name and known_encode procedures (of
9571 
which there are, respectively, 11 and 0 in the current code base), and for
9572 
all places that define gs_font_procs structures statically or initialize the
9573 
callbacks dynamically (of which there are currently only two, one in
9574 
gsfont.c and one in zbfont.c). There are also 3 identical places in the
9575 
GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
9576 
minor changes, with a small net reduction in code. 2) Deletes the
9577 
char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
9578 
three current xfont implementations implements it. 3) Changes the
9579 
char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
9580 
callback procedure, it takes a const gs_string * argument that is the actual
9581 
glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
9582 
NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
9583 
(At present, there are 3 implementors, none of which use the glyph_name
9584 
callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
9585 
procedure, which is still required for other purposes, to gs_font_procs,
9586 
changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
9587 
gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
9588 
clients, but they must already change because of item (1) above. 5)
9589 
Eliminates the registered_Encodings array in the PostScript interpreter,
9590 
substituting the C representation of the known Encodings.

9645

9654 
	- pdfwrite could not convert a CIEBased color space with input
9655 
domains larger than [0..1] to an ICCBased space, because the ICC profile
9656 
specification inherently limits inputs to this range. The fix required
9657 
explicitly rescaling the decoding of the color data in many different places
9658 
when such a color space was involved: the Decode arrays in images; the
9659 
tintTransform functions for Separation and DeviceN color spaces; the
9660 
Background, Function, and Decode for shadings. While this was only a
9661 
performance problem, it could be a very severe one, because it caused images
9662 
using such extended-domain CIEBased spaces to revert to zillions of tiny
9663 
rectangles. This change completes the ability of pdfwrite to convert
9664 
PostScript color spaces, aside from DeviceN and Separation spaces which are

9702 
	- An incorrect subscript computation, and an incorrect choice of
9703 
allocator, in the image compression chooser code caused SEGVs. Fixes 14 of

9706 
	- pdfwrite produced incorrect output for ShadingType 6 and 7
9707 
shadings if the coordinate and color data came from an array rather than a
9708 
stream or string. Partially fixes pdfwrite regressions 446-01.ps and

483-05.ps. (gdevpdfv.c [1.17]: 2002/06/14 15:47:20 lpd)
9710 
	- If a Shading used a color space other than the 3 basic Device
9711 
spaces, its ColorSpace reference could be corrupted, because the ColorSpace
9712

9839 
Cleans up a number of design problems in the font callback procedures: 1)
9840 
Eliminates the gx_xfont_callbacks structure entirely. The known_encode
9841 
procedure is no longer needed: the new facilities in gscencs.[hc] make it
9842 
unnecessary, and none of the three implementors of the xfont interface use
9843 
it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
9844 
change for all clients of the glyph_name and known_encode procedures (of
9845 
which there are, respectively, 11 and 0 in the current code base), and for
9846 
all places that define gs_font_procs structures statically or initialize the
9847 
callbacks dynamically (of which there are currently only two, one in
9848 
gsfont.c and one in zbfont.c). There are also 3 identical places in the
9849 
GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
9850 
minor changes, with a small net reduction in code. 2) Deletes the
9851 
char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
9852 
three current xfont implementations implements it. 3) Changes the
9853 
char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
9854 
callback procedure, it takes a const gs_string * argument that is the actual
9855 
glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
9856 
NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
9857 
(At present, there are 3 implementors, none of which use the glyph_name
9858 
callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
9859 
procedure, which is still required for other purposes, to gs_font_procs,
9860 
changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
9861 
gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
9862 
clients, but they must already change because of item (1) above. 5)
9863 
Eliminates the registered_Encodings array in the PostScript interpreter,
9864 
substituting the C representation of the known Encodings.

Fixes problems:
9960 
	- Remove "/tfopdict undef". tfopdict was defined in v.6.01 but the
9961 
definition was since removed. Fix for bug #511232 by Alex Cherepanov.
9962 
(lib/pdf_draw.ps [1.44]: 2002/04/10 02:23:08 ray)
9963 
	- Handle Widths and Encoding arrays in PDF Font objects that are too
9964 
small by using reasonable defaults. Adobe Acrobat Reader handles files with
9965 
these problems. Fix for Artifex customer 861 for SourceForge bug#538398.
9966 
(lib/pdf_font.ps [1.32]: 2002/04/10 15:16:00 ray)
9967 
	- Annotations with empty AP dictionary caused a failure. Providing
9968 
more tolerance rather such APs are invalid. Source Forge bug "[ 538428 ]
9969 
empty appearance streams". (lib/pdf_draw.ps [1.45]: 2002/04/29 09:59:27
9970 
igor)
9971 
	- More tolerance to inconsistent stream length in PDF reader. Source
9972 
Forge bug "[ 538042 ] /syntaxerror in --token--". (lib/pdf_base.ps [1.21]:
9973 
2002/04/30 10:46:20 igor)
9974 
	- More compatibility to Adobe interpreters in 'eexec'. This is
9975 
NON-BACKWARD-COMPATIBLE change. Now eexec skips all whitespaces at the
9976 
beginning of input stream, except for PFBDecode output. Thanks to L. Peter
9977 
Deutsch for participation. Source Forge bug "[ 428891 ] Undefined commands
9978

9979 
	- Make PDF reader tolerant to singular matrix in Tj. Source Forge
9980 
bug "[ 538055 ] /undefinedresult in --currentpoint--". (The solution was
9981 
suggested by L. Peter Deutsch.) (lib/pdf_ops.ps [1.24]: 2002/05/08 15:51:58
9982 
igor)
9983 
	- Acrobat Reader apparently ignores or clamps 'setflat' parameter
9984 
values when rendering PDF. This change emulates that behaviour by clamping
9985 
the flatness parameter to a max of 1. Fixes SourceForge bug #555657 for
9986 
Artifex customer #150. (lib/pdf_draw.ps [1.46]: 2002/05/22 17:29:37 ray)
9987 
	- GS doesn't process PDF files without the required key /FontName in
9988 
FontDescriptor dict. Adobe Acrobat Reader handles these out of spec files,
9989 
so we also allow this. To fix this, now uses /BaseFont key when /FontName is
9990 
missing. SF#515475. (lib/pdf_font.ps [1.34]: 2002/05/30 03:32:03 jeong)
9991 
	- Acrobat Reader apparently processes badly formed numbers that have
9992 
a '-' after the '.' by ignoring the fraction. If this type of tokenerror is
9993 
detected, issue an error message and change the scanning rules to do the
9994 
same as Adobe. SourceForge bug #558473 for Artifex customer #561.
9995 
(lib/pdf_base.ps [1.22]: 2002/05/31 17:14:34 ray)
9996 
	- Yet another change to allow our PDF intperpreter to tolerate an
9997 
out of spec PDF file that Acrobat Reader (and Glance pdf tools) handle. This
9998 
file had an 'endobj' without an 'endstream' terminating a stream. Fixes SF
9999 
bug #570262 for Artifex customer #1060. (lib/pdf_base.ps [1.23]: 2002/06/18
10000 
05:37:05 ray)
10001 
	- Correct the pdfformaterror message issued when an 'endobj' is seen
10002 
instead of 'endstream' and add a comment in the file about the error. Thanks
10003 
to Dan Coby for the suggestions improving the previous patch.
10004 
(lib/pdf_base.ps [1.24]: 2002/06/18 06:29:21 ray)
10005 
	- Use actual white point in /Lab spaces, rather than relying on
10006 
default. Fixes problem in regression file test.pdf. (lib/pdf_draw.ps [1.47]:
10007 
2002/06/20 20:26:48 raph)
10008 
	- Prevents /typecheck in --length-- if given a file with an Encoding
10009 
dictionary with a Differences list has no BaseEncoding. This is perfectly
10010 
legal -- the base encoding is the font's built-in encoding or
10011 
StandardEncoding, per the PDF Reference (depending on whether or not the
10012 
font is flagged as "symbolic"). Fixes SF bug #566042.
10013 
(lib/pdf_font.ps [1.37]: 2002/06/21 06:49:50 ray)
10014 
	- Previous fix for SF bug #566042 caused a regression by defining an
10015 
Encoding array filled with .notdef too aggresively. Only create this array
10016 
when we need to update it with /Differences. Some regression files were
10017 
onechar.pdf, xngnews.pdf. The testfont.pdf file of 566042 still runs OK.
10018 
(lib/pdf_font.ps [1.38]: 2002/06/21 07:46:37 ray)
10019 
	- Fixes regressions caused by previous update including errors with
10020 
ImageProb2*.pdf and aaon97_p7.pdf. Removes logic that set StandardEncoding
10021 
if BaseEncoding wasn't set since this caused aaon97_p7 regression. Only use
10022 
.notdefEncoding if updateencoding sees a null encoding input. This is the
10023 
"real" fix for SF bug #566042. (lib/pdf_font.ps [1.39]: 2002/06/21 18:38:21
10024 
ray)
10025 
	- Wrong Widths array entry could sometimes be used when the Encoding
10026 
(after Differences applied) mapped codes to the same glyph. Logic introduced
10027 
in rev 1.22 only prevented some of the incorrect Width. Fixes SF bug# 570784
10028 
for Artifex customer #150. (lib/pdf_font.ps [1.40]: 2002/06/22 05:48:47 ray)
10029 
	- If the Differences list in the Encoding of an embedded font in a
10030 
PDF was not in increasing order, the encoding array length needed for the
10031 
differences could be miscalculated. Thanks to Dave Slattengren for spotting
10032 
this. No files had been seen (yet) that tripped on this.
10033 
(lib/pdf_font.ps [1.41]: 2002/06/25 18:58:55 ray)
10034 
	- Generates pdfformaterror rather than PostScript error for broken
10035 
PDF files containing unmatched &gt;&gt;. Workaround for SF bug #553812 for
10036 
Artifex customer #580. (lib/pdf_base.ps [1.25]: 2002/06/26 18:35:51 ray)
10037 
	- Generates pdfformaterror rather than PostScript error for broken
10038 
PDF files containing unmatched &gt;&gt; in trailer. Workaround for SF bug
10039 
#571851. (lib/pdf_main.ps [1.50]: 2002/06/26 18:37:16 raph)
10040 
	- Add the option -dUseCropBox to set the page size from the CropBox
10041 
rather than the MediaBox. This is appropriate when using ghostscript to view
10042 
PDF files or convert to bitmaps. It probably isn't appropriate for printing.
10043

10044 
#538267 "Problems with Media Box in PDF and PS interpreter".
10045 
(lib/pdf_main.ps [1.51]: 2002/06/28 10:55:43 ghostgum)
10046 
	- When drawing PDF annotation links which are missing a /Border,
10047 
assume the default /Border [0 0 1]. Previously ghostscript assumed that
10048 
links without a /Border should not be drawn, which is contrary to the PDF
10049 
specification. (lib/pdf_draw.ps [1.48]: 2002/06/28 23:10:10 ghostgum)
10050 
	- If a PDF annotation specified other than the default color with
10051 
/C, pass this into the pdfmark logic as /Color. (lib/pdf_main.ps [1.52]:

Fixes problems:
10070 
	- Skip the (potentially time consuming) work of setting the color
10071 
space if it is the same as the currentcolorspace. Fixes SF #539327 for
10072 
Artifex customer #830. (lib/gs_lev2.ps [1.15]: 2002/04/06 01:18:56 ray)
10073 
	- Check the return code from gs_upathbbox() and zero the bbox if
10074 
there is no current point. Propagate other errors up. Adobe implementations
10075 
throw nocurrentpoint error, but this is not valid per the PLRM. Fix for
10076 
#520972 by Alex Cherepanov. (zupath.c [1.5]: 2002/04/09 22:54:00 ray)
10077 
	- Delete code that caused unshifted arrow keys to enter garbage
10078 
chars into the command line buffer. Now arrow keys scroll the image window
10079 
regardless of the shift state. Fix by Alex Cherepanov. (dwtext.c [1.8]:
10080 
2002/04/09 23:26:29 ray)
10081 
	- Fix for #540871. Clean up compiler warnings in zfsample.c. Note:
10082 
The addition of two include files in zfsample.c forces a change in
10083 
dependencies in int.mak. (zfsample.c [1.6]: 2002/04/11 02:18:14 dan)
10084 
	- Adding any of the base 14 fonts to the NeverEmbed list produced
10085 
broken output in PDF level 1.3 and above. Makes the 'default', 'screen', and
10086 
'ebook' parameter sets not embed the base 14 fonts. (The documentation
10087 
already said this was the case, even though it wasn't.) This is a partial
10088 
fix for SourceForge bug #438957. (lib/gs_pdfwr.ps [1.16]: 2002/04/12
10089 
19:38:33 lpd)
10090 
	- The Matrix entry of ShadingType 1 shading dictionaries was
10091 
required; it is now (correctly) optional. (zshade.c [1.9]: 2002/04/14
10092 
02:48:26 lpd)
10093 
	- ShadingType 1 shadings whose Function was an array required the
10094 
individual functions to take 1 argument, rather than the correct 2; shadings
10095 
whose Function was not an array didn't check that the function took the
10096 
correct number of arguments. (The Genoa FTS does not check either of these.)

10102 
This is a tuned parameter that may need to be adjusted in the future if
10103 
-dNOGC runs significantly faster than the normal case. The previous values
10104 
were established a long time ago when memory was a more expensive resource.

	- ShadingType 4-7 shadings with a Function and with data coming from
10110 
a stream rather than an array incorrectly expected N value ranges in their
10111 
Decode array, where N is the number of components in the color space, rather
10112 
than a single range for the function argument. Finishes fixing SourceForge

10116 
	- Previous change to optimize setcolorspace (for SF bug #539327)
10117 
caused a regression since the CIE space cache management was confused when
10118 
CIEBased (including ICCBased) colorspace was the base space for some other
10119 
space such as Pattern, Indexed, DeviceN, Separation. The discussion of the
10120 
fix of the cache handling will be in doc/Projects.htm. The .dosetcolorspace
10121 
is now used internally when setting up the base space for the "outer"
10122 
colorspaces. Fixes regression caused by rev 1.15 of gs_lev2.ps and partial

Cleans up a number of design problems in the font callback procedures: 1)
10321 
Eliminates the gx_xfont_callbacks structure entirely. The known_encode
10322 
procedure is no longer needed: the new facilities in gscencs.[hc] make it
10323 
unnecessary, and none of the three implementors of the xfont interface use
10324 
it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
10325 
change for all clients of the glyph_name and known_encode procedures (of
10326 
which there are, respectively, 11 and 0 in the current code base), and for
10327 
all places that define gs_font_procs structures statically or initialize the
10328 
callbacks dynamically (of which there are currently only two, one in
10329 
gsfont.c and one in zbfont.c). There are also 3 identical places in the
10330 
GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
10331 
minor changes, with a small net reduction in code. 2) Deletes the
10332 
char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
10333 
three current xfont implementations implements it. 3) Changes the
10334 
char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
10335 
callback procedure, it takes a const gs_string * argument that is the actual
10336 
glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
10337 
NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
10338 
(At present, there are 3 implementors, none of which use the glyph_name
10339 
callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
10340 
procedure, which is still required for other purposes, to gs_font_procs,
10341 
changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
10342 
gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
10343 
clients, but they must already change because of item (1) above. 5)

Fixes problems:
10458 
	- Compiling with -dPROFILE could cause compiler warnings about
10459 
"memxxx redefined" (memset, memcpy, etc.). (memory_.h [1.5]: 2002/04/08
10460 
20:42:01 lpd)
10461 
	- Indexed color spaces weren't implemented for ShadingType 4-7
10462 
shadings. (gxshade.c [1.9], gxshade.h [1.7], gxshade4.c [1.9]: 2002/04/14
10463 
04:30:47 lpd)
10464 
	- If a shading's Function entry was an array of functions rather
10465 
than a single function, pdfwrite wrote out an invalid Function object with a
10466 
FunctionType of -1. (gsfunc3.c [1.7]: 2002/04/14 06:51:45 lpd)
10467 
	- Radial shading fills with /Extend are now clipped correctly. Also
10468 
Radial shadings with 2 radii for which the difference is small or zero, now
10469 
does as Adobe does. Fixes SourceForge bug #219798, #542457
10470 
(gxshade1.c [1.13]: 2002/04/18 08:12:56 jeong)
10471 
	- Fix : Type2 interpreter state was wrongly backed up for sbw
10472 
fallback. Source Forge bug "[ 541877 ] /invalidfont on Kozuka Mincho".
10473 
(gstype2.c [1.18], gxtype1.c [1.13]: 2002/04/18 14:26:27 igor)
10474 
	- ShadingType 4-7 shadings with a Function incorrectly read N values
10475 
from their data stream, where N is the number of components in the color
10476 
space, rather than a single entry for the function argument. Fixes
10477 
SourceForge #546415. (gxshade.c [1.10]: 2002/04/20 05:27:11 lpd)
10478 
	- The make_scaled procedure for PostScript Calculator Functions
10479 
didn't copy the data_source, causing a memory access error when converting
10480 
the Function to printable form. (gsfunc4.c [1.11]: 2002/04/20 07:05:39 lpd)
10481 
	- Arrayed Output Functions (used internally to represent an array of
10482 
Functions) didn't compute or store their Domain, causing pdfwrite to write
10483 
them incorrectly. (Bug found during development of pdfwrite.)
10484 
(gsfunc3.c [1.9]: 2002/04/20 18:50:36 lpd)
10485 
	- ShadingType 4-7 shadings didn't check the validity of ColorSpace
10486 
and BBox like other shadings, and when used with a Function, didn't check
10487 
that the Function had the correct number of inputs and outputs. (Bug found
10488 
during pdfwrite development.) (gsshade.c [1.7]: 2002/04/21 02:48:36 lpd)
10489 
	- Arrayed Output functions didn't check whether their input and
10490 
output buffers overlapped in memory. This produced incorrect output from
10491 
ShadingType 4-7 shadings with a /Function entry that was an array of N
10492 
1-output Functions rather than a single N-output function. (Bug discovered
10493 
during pdfwrite development.) (gsfunc3.c [1.10]: 2002/04/23 01:10:38 lpd)
10494 
	- Radial shading worked only if the original coordinate unit is
10495 
identical to the coordinate unit of the output device. Now it works for
10496 
every case. Fixes SF#542457. (gxshade1.c [1.14]: 2002/04/23 06:13:58 jeong)
10497 
	- Fixes an incorrect comment; eliminates a redundant initialization.
10498 
(gsfunc3.c [1.11]: 2002/04/23 16:46:30 lpd)
10499 
	- FunctionType 4 functions with more than 1 output didn't scale the
10500 
output properly. (gsfunc4.c [1.12]: 2002/04/23 18:38:52 lpd)
10501 
	- gx_device_clip::memory was not set but used while intersecting
10502 
clip paths. Source Forge bug "[ 547111 ] segfault with pdf using ppmraw".
10503 
(gxclip.c [1.7]: 2002/04/26 08:52:54 igor)
10504 
	- A rounding problem made installation of CIEBased color spaces
10505 
non-idempotent, which could cause seriously incorrect rendering of CIEBased
10506 
colors in the sequence [/CIEBased...] setcolorspace, gsave, [/Pattern
10507 
[/CIEBased...]] setcolorspace, grestore. Fixes SourceForge bug #547695, q.v.
10508 
(gscie.c [1.9], gscie.h [1.9]: 2002/05/07 19:51:53 lpd)
10509 
	- The GS lib would not build. This fix corrects two minor problems.
10510 
The routine gs_abort was added to gslib.c. The unused include file
10511 
gmorecfg.h was removed from vdtrace.c. (gslib.c [1.8], vdtrace.c [1.4]:
10512 
2002/05/08 05:39:12 dan)
10513 
	- A minor cleanup of vdtrace.c . (vdtrace.c [1.5]: 2002/05/08
10514 
06:57:35 igor)
10515 
	- pdfwrite relied on the PostScript interpreter to load and make
10516 
available the known encodings and glyph sets identified in src/gsccode.h.
10517 
With this change, pdfwrite can now be used without a PostScript interpreter,
10518 
and with fonts that do not implement the known_encode callback.
10519 
(gdevpsf2.c [1.19], gdevpsft.c [1.13], gscedata.c [1.1], gscencs.c [1.1],
10520 
gscencs.h [1.1]: 2002/05/12 22:38:08 lpd)
10521 
	- as a result of a recent fix, the CIEBased color cache code for
10522 
ensuring that black (0,0,0) mapped precisely no longer worked.
10523 
(gscie.c [1.10]: 2002/05/15 23:49:39 lpd)
10524 
	- gdevpsf.h didn't define the 'stream' type, which it references.
10525 
(gdevpsf.h [1.14]: 2002/05/17 16:38:12 lpd)
10526 
	- The previous fix for numerical inaccuracies in CIE cache sampling
10527 
could lead to extremely long computation times. (gscie.c [1.11],
10528 
gscie.h [1.11]: 2002/05/19 15:50:00 lpd)
10529 
	- completing "remove dependency of pdfwrite on PS" (gscencs.c [1.3]:
10530 
2002/05/20 06:33:36 igor)
10531 
	- In the output of the PDF 1.4 image buffer to the target device,
10532 
sets color space in graphics state explicitly to RGB (to match the color
10533 
space in the image), and also sets the device in the graphics state to the
10534 
target device. It may be that a better fix would be to make the image work
10535 
even without these explicit state settings, but this seems to work for now.
10536 
Fixes SF #520686. (gdevp14.c [1.10]: 2002/05/22 05:07:48 raph)
10537 
	- In radial shading, if radius of a circle is 0, there was division
10538 
by zero. This is a regression for the fix of SF#219798. Now fixed.
10539 
(gxshade1.c [1.15]: 2002/05/26 05:03:31 jeong)
10540 
	- Increase clist cmd reading buffer size to 4K to be able to handle
10541 
larger halftone bitmaps. The old size of 800 could cause the clist high
10542 
level path logic to revert to 'default' filling which created VERY large
10543 
clist temp files. SourceForge bug 542664 for Artifex customer 710.
10544 
(gxcldev.h [1.7]: 2002/05/29 08:09:59 ray)
10545 
	- Add type cast to prevent problem on OpenVMS (gdevp14.c [1.11]:
10546 
2002/05/31 13:05:58 joukj)
10547 
	- Fixes off-by-one error in loop termination for CIE cache
10548 
initializations. (gscie.c [1.12]: 2002/06/06 06:55:12 raph)
10549 
	- Fixes uninitialized base buffer and failure to properly increment
10550 
a p14_device refcount in the pdf14 imaging code. (gdevp14.c [1.12]:
10551 
2002/06/06 06:57:12 raph)
10552 
	- Fixes a bug in writing "stripped" TrueType fonts. (Only affects
10553 
font copying.) (gdevpsft.c [1.16]: 2002/06/12 22:06:51 lpd)
10554 
	- Limit the number of %disk devices to 7 to prevent problems with
10555 
the Dynalab font installer. Also return %disk devices in numeric order from
10556 
devforall and suppress %disk devices from filenameforall to match Adobe.
10557 
Also correct documentation of devforall (no pattern string used). Thanks to
10558 
Nori Matsushima and Erik Strik for testing of this feature (diskn.dev).
10559 
(gsiodisk.c [1.2]: 2002/06/14 04:04:39 ray)
10560 
	- The automatically generated files src/gscedata.[ch] didn't have a
10561 
RCS Id line. (gscedata.c [1.3], gscedata.h [1.2]: 2002/06/14 13:31:53 lpd)
10562 
	- psf_write_truetype_font and psf_write_cid2_font copied hmtx and
10563 
vmtx rather than getting the actual metrics through the font virtual
10564 
procedures, which produced incorrect output if the font was defined
10565 
incrementally and used MetricsCount. (This only affected pdfwrite.)
10566 
(gdevpsf.h [1.18], gdevpsft.c [1.18]: 2002/06/18 00:31:20 lpd)
10567 
	- Removes incorrect #includes of errors.h, which is a PostScript
10568 
interpreter file, from library files. (gsfcmap1.c [1.3], gxchar.c [1.16]:
10569 
2002/06/19 15:33:01 lpd)
10570 
	- When drawing with anti-aliasing on devices with less than
10571 
8-bit/pixel, extract the correct existing pixel value. (gdevdbit.c [1.5]:
10572 
2002/06/21 22:05:33 ghostgum)
10573 
	- Propagate possible errors from pdf_end_image_binary.
10574 
(gsimage.c [1.7], gsimage.h [1.6], gsptype1.c [1.7], gxccache.c [1.10]:
10575 
2002/06/22 11:16:12 igor)
10576 
	- gxfcache.h didn't #include or define all of its prerequisites.
10577 
(gxfcache.h [1.7]: 2002/06/24 05:14:15 lpd)
10578 
	- Fixes an off-by-1 bug in the code for accessing Subrs in copied
10579 
fonts. (gxfcopy.c [1.4]: 2002/06/24 17:28:11 lpd)
10580 
	- copying a CIDFontType 2 font didn't copy numGlyphs, causing glyphs
10581 
to disappear. (gxfcopy.c [1.6]: 2002/06/24 23:48:31 lpd)
10582 
	- Fixes an off-by-1 error in copying [Global]Subrs.
10583 
(gxfcopy.c [1.7]: 2002/06/25 04:32:48 lpd)
10584 
	- gs_copy_font for CIDFontType 0 fonts didn't copy GlobalSubrs
10585 
correctly. (gxfcopy.c [1.8]: 2002/06/25 05:22:56 lpd)
10586 
	- Two places associated with font writing didn't add in
10587 
subroutineNumberBias when interpreting a Type 1 / Type 2 CharString.
10588 
(gdevpsfx.c [1.15], gxtype1.c [1.14]: 2002/06/25 05:25:45 lpd)
10589 
	- The GSubrs for CIDFontType 0 fonts were not written, possibly
10590 
producing invalid embedded fonts from pdfwrite. Fixes SourceForge #571911.
10591 
(gdevpsf.h [1.19], gdevpsf2.c [1.21]: 2002/06/25 06:52:05 lpd)
10592 
	- Fixes two uninitialized memory reads, by zeroing the gs_allocated
10593 
field of newly allocated allocators, and the userdict_index field of dict
10594 
stacks in newly allocated contexts. (gsalloc.c [1.17]: 2002/06/26 20:01:53
10595 
raph)
10596 
	- Fix uninitialized memory read of pcache-&gt;order.data_memory by
10597 
zeroing it on construction. (gxht.c [1.7]: 2002/06/26 20:03:21 raph)
10598 
	- Code for writing and copying Type 1 fonts didn't correctly handle
10599 
Subrs arrays with null elements. (gdevpsf1.c [1.15], gdevpsf2.c [1.22],
10600 
gxfcopy.c [1.9]: 2002/06/26 23:17:24 lpd)
10601 
	- Allocating the glyphs and names arrays for copied fonts used the
10602 
wrong structure descriptor. (gxfcopy.c [1.10]: 2002/06/27 03:55:39 lpd)
10603 
	- Fixes 3 minor problems with font copying: GC overhead was
10604 
substantial; the components of composite glyphs were not copied; the
10605 
encoding index was not copied when copying a complete font.
10606 
(gxfcopy.c [1.12]: 2002/06/28 01:47:22 lpd)
10607 
	- The size of the version field of the ttf_maxp_t structure was
10608 
defined incorrectly as 2 rather than 4. (This structure wasn't referenced
10609 
anywhere.) (gxttf.h [1.6]: 2002/06/28 05:27:22 lpd)
10610 
	- Font copying did not allocate its tables correctly when copying
10611 
incrementally downloaded TrueType fonts, and did not implement encode_char
10612 
correctly for TrueType fonts when glyph_space == GLYPH_SPACE_NAME. (Only
10613 
affects new pdfwrite text code.) (gxfcopy.c [1.13]: 2002/06/28 22:35:26 lpd)
10614 
	- The return status values from 'sgets' were not handled properly.
10615 
Now the functions that use 'sgets', check the return status and convert them
10616 
into proper gs_errors. SF#569111 (gsmatrix.c [1.6], gsparam2.c [1.6],
10617 
gxclrast.c [1.16]: 2002/07/01 14:27:43 jeong)
10618 
	- The hmtx/vmtx tables generated from the glyph metric data for
10619 
embedded TrueType fonts in PDF output were incorrect, due to a misreading of
10620 
the TrueType spec. (This only affects the new pdfwrite text code: the old
10621 
code does not generate the tables this way.) (gdevpsft.c [1.20]: 2002/07/06

10627 
Changes gs_cmap_t (internal representation of CMaps) to an abstract
10628 
superclass with multiple implementations: standard Adobe CMapType 1,
10629 
TrueType 16-bit cmap (Platform 3, Encoding 1, Format 4), and one-for-one.
10630 
Adds the ability to designate a CMap as Unicode-based. Enhances pdfwrite so
10631 
that composite fonts (including those based on TrueType Unicode fonts) with
10632 
Unicode-based CMaps are embedded in the PDF file with the original text
10633 
preserved and with an appropriate ToUnicode CMap, making the text searchable
10634 
in Acrobat. (gdevpsfm.c [1.10], gsfcid2.c [1.1], gsfcmap.c [1.18],

Restores some performance lost as a result of the fix for SourceForge
10640 
#495414, by skipping a request for glyph widths which is redundant if the
10641 
font doesn't have Metrics or CDevProc. Addresses SourceForge #451456 (a
10642 
general request for better pdfwrite performance), which will be closed after
10643 
this change. (gxfont.h [1.10]: 2002/04/09 23:31:44 lpd)

Adds a make_scaled virtual procedure to Function objects, to create a
10660 
modified Function whose N output values are transformed linearly according
10661 
to a supplied set of N range parameters. This is the first installment for
10662

Changed END_OBJECT_SCAN to call gs_abort() instead of gs_exit in a debug

gs_exit() cleanup. gs_exit() is renamed gs_to_exit() since it is an about to
10691 
terminate cleanup function, it always returns. Both gs_to_exit() and
10692 
gs_abort are client provided functions. The client can have its own special
10693 
cleanup on exit, and the client can decide what it wants to do in the abort
10694 
case: exit, setjump/longjump, ... gp_do_exit() is the way for the client to
10695 
call a system independent exit() this allows for different exit codes on
10696 
unix and vms for instance. Only the client can call this, if so desired from
10697 
their gs_abort(). (gsexit.h [1.7], gslib.c [1.9]: 2002/05/14 14:59:41

10753 
 
10754 
Cleans up a number of design problems in the font callback procedures: 1)
10755 
Eliminates the gx_xfont_callbacks structure entirely. The known_encode
10756 
procedure is no longer needed: the new facilities in gscencs.[hc] make it
10757 
unnecessary, and none of the three implementors of the xfont interface use
10758 
it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
10759 
change for all clients of the glyph_name and known_encode procedures (of
10760 
which there are, respectively, 11 and 0 in the current code base), and for
10761 
all places that define gs_font_procs structures statically or initialize the
10762 
callbacks dynamically (of which there are currently only two, one in
10763 
gsfont.c and one in zbfont.c). There are also 3 identical places in the
10764 
GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
10765 
minor changes, with a small net reduction in code. 2) Deletes the
10766 
char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
10767 
three current xfont implementations implements it. 3) Changes the
10768 
char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
10769 
callback procedure, it takes a const gs_string * argument that is the actual
10770 
glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
10771 
NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
10772 
(At present, there are 3 implementors, none of which use the glyph_name
10773 
callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
10774 
procedure, which is still required for other purposes, to gs_font_procs,
10775 
changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
10776 
gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
10777 
clients, but they must already change because of item (1) above. 5)
10778 
Eliminates the registered_Encodings array in the PostScript interpreter,
10779 
substituting the C representation of the known Encodings.

10970 
<p>
10971 
This is the first development release after the 7.0x series. While
10972 
it is a development release, it is likely to be quite stable and
10973 
robust, largely thanks to automated regression testing.
10974 
 
10975 
<p> Major changes include:
10976 
 
10977 
<ul>
10978 
<li>Support for external font renderers such as Agfa UFST.
10979 
 
10980 
<li>An optional "diskn" feature that emulates the "%disk" devices
10981 
found on some Adobe printers.
10982 
 
10983 
<li>The <tt><b>-dSAFER</b></tt> flag now tightens read access to
10984 
arbitrary files, as well as write access. Thus,
10985 
<tt><b>-dSAFER</b></tt> in this release is equivalent to
10986 
<tt><b>-dSAFER -dPARANOIDSAFER</b></tt> in 7.04. This will break some
10987 
viewers, notably gv.
10988 
 
10989 
</ul>
10990 
 
10991 
<p> In addition, the following improvements have been merged from
10992 
the 7.04 release:
10993 
 
10994 
<ul>
10995 
 
10996 
<li>A rather serious security hole, where PostScript code could cause
10997 
arbitrary commands to be executed, has been patched.
10998 
 
10999 
<li>This release integrates the IJS driver, which makes it much easier
11000 
to add and upgrade printer drivers without needing to recompile
11001 
Ghostscript.
11002 
 
11003 
<li>There is a configure script for automatically configuring the
11004 
build system on Unix platforms. Those who enjoy the fun of hand-editing
11005 
the makefile are still welcome to do so.
11006 
 
11007 
</ul>
11008 
 
11009 
<p>
11010 
And, of course, the usual bug fixing and performance enhancement.
11011 
 
11012 
<p>
11013 
There has also been considerable development of our DeviceN
11014 
implementation and related color work on a private branch. These new
11015 
features are <em>not</em> included in this release. We expect to merge
11016 
them into the main branch soon.
11017 
 
11018 
<p>
11019 
There exists another private branch which integrates PCL and PostScript/PDF
11020 
in the same executable. Again, that work is not reflected in this
11021 
release.

11147 
(Interpreter)
11148 
	- Updates clients and implementors for the new glyph outline data
11149 
structure.
11150 
	- -dSAFER flag now restricts read access to arbitrary files in
11151 
addition to restricting write access.
11152 
	- While not strictly an incompatible change, authors of drivers
11153 
with potential security implications are encouraged to review the
11154 
security changes, including the LockSafetyParams mechanism.
11155 
 
11156 
(Library)
11157 
	- Changes all procedures for getting glyph outline data to return
11158 
the data by storing it into a gs_glyph_data_t structure that includes memory
11159 
management information.  This is a NON-BACKWARD-COMPATIBLE change to both
11160 
implementors and clients.  It corrects a significant design error: formerly
11161 
these procedures encoded memory management information in their return code,
11162 
which was obscure and error-prone.  See src/gsgdata.[hc].

(doc/C-style.htm [1.23]: 2002/01/16 16:05:54 lpd)
11179 
	- Improve security in a (mostly) backward compatible fashion adding
11180 
more flexible file access paths (PermitFile...) as user paramters and adding
11181 
the facility to return to NOSAFER mode after running jobs (files/procedures)
11182 
in SAFER mode. This should address SF bug #474582 and eliminate the need for
11183

Improve security for device related access to the file system and to pipes
11290 
by allowing the dangerous parameters to be locked (for example, OutputFile).
11291 
The locking is performed after command line parameters are established.
11292 
Locking is not turned on by default as a result of this change, but
11293 
-d.LockSafetyParams=true can be added to the command line to accomplish
11294 
this. Related to SF bug #474582 (sort of). (doc/Language.htm [1.35]:

</pre><h2><a name="7.20-Procedures"></a>Procedures</h2><pre>
11581 
 
11582 
Fixes problems:
11583 
	- tmake recognized the end of a rule body by a blank line, rather
11584 
than by a line that didn't begin with a tab. Fixes SourceForge #415170.
11585 
(toolbin/tmake.tcl [1.4]: 2001/10/24 05:45:55 lpd)
11586 
	- the icclib makefile comments were out of date; the build rule
11587 
referred to gs_stdio_h, which no longer exists; the build rule for gsicc.o
11588 
referred to icc_h, which was not defined at that point. (gs.mak [1.7],
11589 
icclib.mak [1.4], lib.mak [1.57]: 2001/10/25 21:17:16 lpd)
11590 
	- the recent (previous) update to tmake.tcl omitted a line, which
11591 
caused the detection of out-of-date files to stop working.
11592 
(toolbin/tmake.tcl [1.6]: 2001/10/25 22:02:11 lpd)
11593 
	- lib.mak failed to include the dependency of gxdevcli.h on
11594 
gstparam.h. (lib.mak [1.58]: 2001/10/31 07:10:59 lpd)
11595 
	- makes png the default device on macos which is better supported
11596 
than the pbm. (macosx.mak [1.2]: 2001/11/25 06:42:59 giles)
11597 
	- Repairs code problems with the fix for bug #224056: non-re-entrant
11598 
code, bad formatting, unused variables and computations, and a missing
11599 
#include. (int.mak [1.53]: 2001/12/07 05:41:59 lpd)
11600 
	- For images specified in general CIEBased color spaces, pdfwrite
11601 
would divide the image into tiny rectangles. If the output level is PDF 1.3
11602 
or higher, pdfwrite now converts the CIEBased color space to an ICCBased
11603 
space if possible. (devs.mak [1.48]: 2001/12/13 18:24:05 lpd)
11604 
	- Fix for #474544. Corrects inability to convert valid DeviceN tint
11605 
transform functions into type 4 functions. Valid operator names were not
11606 
being recognized unless the tint transform function had been bound. One of
11607 
two fixes required for this problem. Customer #710. (int.mak [1.57]:
11608 
2002/01/11 05:09:22 dancoby)
11609 
	- Fix for #474544. This is the second of two fixes required for this
11610 
problem. This fix creates a type 0 function which implements a "color cube"
11611 
for those tint transform functions which cannot be converted into a type 4
11612 
function. Customer #710. Note: There is one more revision planned for this
11613 
effort. This revision will make the buildcolorcube operator into a more
11614 
general buildsampledfunction. This will allow its use in other situations.
11615 
(int.mak [1.58]: 2002/01/17 05:53:40 dancoby)
11616 
	- Disables optimization on OpenVMS, because some OpenVMS C compilers
11617 
produce incorrect code for gdevpsfx.c. Fixes SourceForge #508722.
11618 
(openvms.mak [1.19], openvms.mmk [1.14]: 2002/02/05 19:54:14 lpd)
11619 
	- Fix 3 of 3 for #474544 "Core dump - shfill error with DeviceN". 1.
11620 
Recognizes already encapsulated tint transform functions. 2. Generalizes the
11621 
color cube logic for use in other situations. 3. Uses the domain of the
11622 
alternate color space for the range of the tint transform function.
11623 
(int.mak [1.60]: 2002/02/06 02:35:11 dancoby)
11624 
	- ps2pdf14 was not being installed by unixinst.mak. Fixes
11625 
SourceForge bug #508607. (unixinst.mak [1.22]: 2002/02/06 07:16:17 jackiem)
11626 
	- Fixes cvs2hist.py to be branch-aware, changing log selection
11627 
policy from "all logs more recent than the date of the last tag" to "all
11628 
logs along the current branch more recent than the reference tag given in
11629 
the -j option". (toolbin/cvs2hist.py [1.10]: 2002/02/06 21:11:54 raph)
11630 
	- pkmraw device was not built by Windows makefile, but it is
11631 
required for regression testing. (msvc32.mak [1.23]: 2002/02/18 11:22:17
11632 
igor)
11633 
	- ijs.mak had the wrong license header (ijs.mak [1.3]: 2002/02/19
11634 
23:59:34 giles)
11635 
	- reverts the license of ijs.mak to AFPL; the previous change was
11636 
intended for the GPL branch. (ijs.mak [1.4]: 2002/02/20 00:16:00 giles)
11637 
	- check_docrefs didn't pass the gsroot parameter down far enough.
11638 
(toolbin/tests/check_docrefs.py [1.3]: 2002/02/20 07:10:14 lpd)
11639 
	- The Ghostscript test class didn't initialize the new member
11640 
gsoptions. (bug introduced by Windows portability patch)
11641 
(toolbin/tests/gstestgs.py [1.3]: 2002/02/20 07:14:35 lpd)
11642 
	- The check_dirs test script still tried to check
11643 
toolbin/regression, which no longer exists.
11644 
(toolbin/tests/check_dirs.py [1.3]: 2002/02/21 22:19:03 lpd)
11645 
	- The check_source test script didn't properly skip src/gconf.h, and
11646 
it was too strict about the form of double-inclusion protection for header
11647 
files. (toolbin/tests/check_source.py [1.3]: 2002/02/21 22:22:49 lpd)
11648 
	- Add LICENSE file and the few files generated by autogen.sh to the
11649 
allowed files in check_dir.py. (toolbin/tests/check_dirs.py [1.5]:
11650 
2002/02/22 00:34:54 jack)
11651 
	- The check_docrefs test script skipped over directories named by
11652 
links. (toolbin/tests/check_docrefs.py [1.6]: 2002/02/22 02:42:35 lpd)
11653 
	- Include gs_resmp.ps into the prelude with ADDMOD rather than
11654 
.runlibfile (suggested by Raymond J. Johnston), and increase MSVC compiler
11655 
heap for building gs_init.c with COMPILE_INITS=1. Source Forge bug "[ 526192
11656 
] Broken COMPILE_INITS". (int.mak [1.64], msvccmd.mak [1.9]: 2002/03/06
11657 
08:55:16 igor)
11658 
	- Second attempt to fix COMPILE_INITS=1. This statically embeds all
11659 
gs_*.ps files, xlatmap and FAPIconfig. Source Forge bug "[ 526192 ] Broken
11660 
COMPILE_INITS". (int.mak [1.65]: 2002/03/07 10:52:06 igor)
11661 
	- Definition for gsiodisk.$(OBJ) was multiply defined. Remove the
11662 
one that is not dependent on the diskn.dev FEATURE. (lib.mak [1.66]:
11663 
2002/03/15 06:25:13 ray)
11664 
	- remove -fno-common from the standard gcc LDFLAGS. It is only
11665 
required at compile time and doesn't need to be passed to the linker.
11666 
(macosx.mak [1.7], unix-gcc.mak [1.29]: 2002/03/28 23:12:09 giles)
11667 
	- base release date on UTC rather than local time
11668 
(version.mak [1.43]: 2002/03/29 00:36:20 giles)
11669 
	- use UTC universally in the prerelease check script to avoid
11670 
spurious errors due to timezone differences (toolbin/pre.tcl [1.6]:
11671 
2002/03/29 00:44:34 giles)
11672 
	- gsfont.h didn't define gs_matrix as an opaque type, causing
11673 
clients of gsfont.h to include gsmatrix.h unnecessarily. (lib.mak [1.68]:
11674 
2002/03/29 00:48:21 lpd)
11675 
	- Makes pathname manipulation in check_dirs.py and check_docrefs.py
11676 
more portable and robust. (toolbin/tests/check_dirs.py [1.6],
11677 
toolbin/tests/check_docrefs.py [1.7]: 2002/03/29 02:32:54 raph)
11678 
	- Change spaces at start of rule to a single tab required by some
11679 
makes. (winint.mak [1.14]: 2002/04/02 16:27:56 ray)
11680 
	- Correct vdtrace.h dependencies. This eliminates &gt;300 lines of
11681 
output from the gsmake.tcl makefile check tool. (int.mak [1.68],
11682 
lib.mak [1.69]: 2002/04/02 19:34:37 ray)
11683 
	- .dev was left off of uniprint.dev in a DEVICES macro
11684 
(msvc32.mak [1.29]: 2002/04/03 20:14:28 ray)
11685 
 
11686 
Updates version number to 7.10 to indicate that this is now the development
11687 
branch. (version.mak [1.37]: 2001/10/20 09:25:22 raph)
11688 
 
11689 
Changes all procedures for getting glyph outline data to return a structure
11690 
that includes memory management information. This is a
11691 
NON-BACKWARD-COMPATIBLE change to both implementors and clients. It corrects
11692 
a serious design error: formerly these procedures encoded memory management
11693 
information in their return code, which was obscure and error-prone.
11694

tcl scripts. (toolbin/tmake [1.1]: 2002/01/08 07:21:54 lpd)
11749 
 
11750 
Adds a very modest checksource script for checking the conformance of source
11751

11752 
be run as part of nightly regression testing. (toolbin/pre.tcl [1.2]:

11992 
Adds support for compilation against a standard shared libjpeg. It is
11993 
believed that non-baseline compliant DCTEncoded data, permitted by early
11994 
versions of postscript, is now extremely rare and the prohibition against
11995 
SHARE_JPEG=1 may reasonably be removed. The autoconf build will prefer a
11996 
local copy of the jpeg source, in which case the D_MAX_BLOCKS_IN_MCU patch
11997 
will still be applied. If no such local copy is found, it will try to find a
11998 
shared library on the system. For all unix builds, if $(JSRCDIR)/jmemsys.h
11999 
cannot be found, we define DONT_HAVE_JMEMSYS_H and include our own versions
12000 
of the libjpeg memory manager prototypes. The default allocator in the
12001 
shared library is overridden by the ghostscript one at link-time. While this
12002 
may be implementation-dependent, it appears to function as desired on at
12003 
least GNU/Linux and Solaris. Also changes the autoconf build to prefer local
12004 
zlib and libpng source, and cleans up some variable names.

Fixes problems:
12023 
	- There were 3 unused declarations of the variable 'buf'.
12024 
(ziodevsc.c [1.4]: 2001/11/22 04:57:21 lpd)
12025 
	- remove unnecessary include in dxmainc.c. (dxmainc.c [1.5]:
12026 
2001/11/25 07:52:55 giles)
12027 
	- ps2ascii was broken (probably for a long time) because it still
12028 
used NOBIND rather than DELAYBIND. Fixes SourceForge #485029.
12029 
(lib/ps2ascii [1.4], lib/ps2ascii.bat [1.4], lib/ps2ascii.cmd [1.2],
12030 
lib/ps2ascii.ps [1.4]: 2001/12/08 15:43:07 lpd)
12031 
	- some files were missing the RCS 'Id' line with the last
12032 
modification date. partial fix for Sourceforge bug #500922.
12033 
(lib/acctest.ps [1.2], lib/decrypt.ps [1.2], lib/landscap.ps [1.2],
12034 
lib/level1.ps [1.2], lib/pf2afm.ps [1.4], lib/printafm.ps [1.2],
12035 
lib/viewjpeg.ps [1.2]: 2002/01/09 20:35:32 giles)
12036 
	- some files were missing the RCS 'Id' line with the last
12037 
modification date. partial fix for Sourceforge bug #500922. (gp_mac.c [1.3],
12038 
gp_macio.c [1.3]: 2002/01/09 21:04:20 giles)
12039 
	- On IA64 CPUs, objects were only aligned on 8-byte boundaries, not
12040 
16-byte. (It may be that only jmpbuf structures actually need 16-byte
12041 
alignment, but gcc and glibc malloc align all objects that way.) Fixes
12042 
SourceForge bug #502866. Also cleans up some minor coding issues in
12043 
genarch.c. (genarch.c [1.3]: 2002/01/16 16:09:20 lpd)
12044 
	- Most of the calls of gs_[main_]init1 didn't check the return value
12045 
for errors. (gserver.c [1.4]: 2002/01/18 00:43:10 lpd)
12046 
	- Incorporate patch from Tim Waugh of RedHat to allow ps2pdfwr to
12047 
correctly process files with spaces in their names. Peter's earlier fix
12048 
missed a few enclosing "'s for output files. Fixes Sourceforge bug #505338.
12049 
(lib/ps2pdfwr [1.7]: 2002/01/22 20:25:44 jackiem)
12050 
	- Improve security in a (mostly) backward compatible fashion adding
12051 
more flexible file access paths (PermitFile...) as user paramters and adding
12052 
the facility to return to NOSAFER mode after running jobs (files/procedures)
12053 
in SAFER mode. This should address SF bug #474582 and eliminate the need for
12054 
the RedHat PARANOIDSAFER patch. (gp_macio.c [1.4], gp_ntfs.c [1.6],
12055 
gp_os2.c [1.11], gp_vms.c [1.8]: 2002/01/24 06:33:33 rayjj)
12056 
	- Extra (old) parameters to gp_file_name_concat_string removed.
12057 
(gp_ntfs.c [1.7]: 2002/02/01 08:03:46 rayjj)
12058 
	- File enumeration on VMS doesn't enumerate "*" as all files,
12059 
needing "*.*" similar to gp_dosfe.c. PostScript FONTPATH scanning and PCL
12060 
font loading failed prior to this fix. Filenames that already have a "."
12061 
prior to the trailing "*" are not modified. (gp_vms.c [1.9]: 2002/02/06
12062 
01:07:54 rayjj)
12063 
	- Typos (" used when ' was needed) fixed. So much for desk checking
12064 
:-( (gp_vms.c [1.10]: 2002/02/08 04:37:56 rayjj)
12065 
	- Fixes pdf2dsc to open input file before .setsafe, so that it works
12066 
even when SAFER locks down read file access. (lib/pdf2dsc.ps [1.4]:
12067 
2002/02/13 17:28:08 raph)
12068 
	- pdfopt didn't handle pages with no Contents, and didn't handle
12069 
files in which any objects (such as resources) were referenced from both the
12070 
first page and later pages. Also adds more tracing output to pdfopt (with
12071 
-dPDEBUG). Fixes SourceForge #516628. (lib/pdfopt.ps [1.11]: 2002/02/19

12088 
Replaces references of 'FontManagerLib' with 'FontManager' to match the
12089 
Universal Headers stub shipped with Metrowerks CW 6.3. Also disables the
12090 
warning about unused arguments since we have a lot of those be design and
12091 
they accounted for the majority of the warning output on CodeWarrior. The
12092 
macos shlib now builds and works 'out of the box'. (macgenmcpxml.sh [1.2]:

	- Fixes a %ld format with an int argument. (gdevpsu.c [1.8]:

2001/11/22 05:10:01 lpd)
12275 
	- Setting any of the pdfwrite xxxProfile "distiller" parameters

12277

12278 
	- some files were missing the RCS 'Id' line with the last
12279

(gdevcgm.c [1.4], gdevmac.c [1.4]: 2002/01/15 04:44:09 rayjj)
12286 
	- epswrite generates "grestore gsave" while changing a clipping
12287 
path, so the internal graphic state and the output document's graphic state
12288 
become unsynchonized. Particularly this looses the current color. Source

12295 
	- The previous version of src/gdevps.c was checked in with
12296 
DOS/Windows (^M^J) EOLs rather than Unix (^J) EOLs, causing some C compilers
12297 
to reject it. (gdevps.c [1.21]: 2002/02/05 05:09:08 lpd)
12298

Improve security for device related access to the file system and to pipes
12351 
by allowing the dangerous parameters to be locked (for example, OutputFile).
12352 
The locking is performed after command line parameters are established.
12353 
Locking is not turned on by default as a result of this change, but
12354 
-d.LockSafetyParams=true can be added to the command line to accomplish
12355 
this. Related to SF bug #474582 (sort of). (gdevcgm.c [1.3],

Fixes problems:
12464 
	- Repeated use of the same color space wrote multiple ColorSpace
12465 
resources rather than a single one. Fixes the pdfwrite part of SourceForge
12466 
bug #475219: separate changes to pdf_draw.ps and pdf_ops.ps fix the
12467 
interpreter part of the bug. (gdevpdfc.c [1.18]: 2001/11/06 17:34:30 lpd)
12468 
	- Reading from /dev/random can cause long blocking on Solaris 8, so
12469 
we only attempt it (on all systems) if non-blocking I/O is available, and we
12470 
try /dev/urandom first. Fixes SourceForge #482048. (gdevpdf.c [1.39]:
12471 
2001/11/21 22:14:22 lpd)
12472 
	- CIE color conversion could be very inaccurate if it didn't use
12473 
interpolation when cached sampled values were near zero. This fix detects
12474 
numerically sensitive areas and uses interpolation (which is computationally
12475 
expensive) only in those areas. Fixes SourceForge #465921.
12476 
(gdevpdfc.c [1.19]: 2001/12/09 00:03:37 lpd)
12477 
	- For images specified in general CIEBased color spaces, pdfwrite
12478 
would divide the image into tiny rectangles. If the output level is PDF 1.3
12479 
or higher, pdfwrite now converts the CIEBased color space to an ICCBased
12480 
space if possible. (gdevpdfc.c [1.20], gdevpdfc.h [1.1], gdevpdfk.c [1.1]:
12481 
2001/12/13 18:24:05 lpd)
12482 
	- the prototype for pdf_text_process was in a .c file rather than a
12483 
.h file. (gdevpdff.h [1.12], gdevpdft.c [1.37]: 2002/01/15 23:07:02 lpd)
12484 
	- pdfwrite incorrectly handled Metrics[2] and CDevProc by writing
12485 
Widths that differed from the widths in the underlying font. pdfwrite now
12486 
positions characters individually in this case, like Acrobat Distiller.
12487

12489 
	- Work around an apparent Acrobat Reader 5 bug -- it gives an error
12490 
for images with a color-key mask, at least for 1-bit-deep images using an
12491 
Indexed color space -- by converting the image to an ordinary masked image.

12494 
	- Setting the parameters for a stroked font could reset other text
12495

12496 
Fixes SourceForge bug #505011. (gdevpdfs.c [1.9]: 2002/01/24 16:37:53 lpd)
12497 
	- pdfwrite often gave an error if a name with embedded special
12498 
characters was a key or value in a pdfmark dictionary. Fixes SourceForge

#505877. (gdevpdfr.c [1.5]: 2002/01/29 02:54:43 lpd)
12500 
	- pdfwrite could output Indexed color spaces with more than 256
12501 
entries, or images with more than 8 bits per component, neither of which PDF
12502 
supports. This patch causes the latter to revert to the
12503 
millions-of-tiny-rectangles representation, which is not adequate in the
12504 
long run, but is at least valid output. Fixes SourceForge #513910, for the
12505 
moment. (gdevpdfc.c [1.21], gdevpdfi.c [1.26]: 2002/02/11 16:26:20 lpd)
12506

12507 
caller. (gdevpdfj.c [1.8]: 2002/02/12 21:55:31 lpd)
12508 
	- (1) real_widths were missed in public_st_pdf_font; (2)
12509 
pdf_finalize_font_descriptor was called twice (form pdf_font_notify_proc and
12510

12580 
vertically. (lib/pdf_ops.ps [1.19]: 2001/12/22 07:24:50 masata-y)
12581 
	- Fix for "[ #505041 ] /typecheck in --setcolor--". Customer 150. An
12582 
error in counting the number of values by the PDF interpreter was causing an
12583 
incorrect number of values to be sent to setcolor. This in turn caused a
12584 
typecheck. (lib/pdf_main.ps [1.37]: 2002/01/30 00:43:29 dancoby)
12585 
	- Some PDF files don't have balanced q/Q operators (gsave/grestore)
12586 
that left extra dicts on the dictstack. Save the dictstack depth before the
12587 
page and pop any left over elements. Fix for SF #495088 for customer #870.
12588 
(lib/pdf_main.ps [1.38]: 2002/02/05 20:50:25 rayjj)
12589 
	- Extra dict was left on the ostack by rev 1.38 (introduced when

	- Another improvement for the hack in 'getfontmetrics', which deals
12595

12699 
	- CIE color conversion could be very inaccurate if it didn't use
12700 
interpolation when cached sampled values were near zero. This fix detects
12701 
numerically sensitive areas and uses interpolation (which is computationally
12702 
expensive) only in those areas. Fixes SourceForge #465921. (zcie.c [1.6],

	- pdfwrite incorrectly handled Metrics[2] and CDevProc by writing
12735 
Widths that differed from the widths in the underlying font. pdfwrite now

positions characters individually in this case, like Acrobat Distiller.

Fixes SourceForge #495414. (zchar1.c [1.9]: 2002/01/17 05:13:24 lpd)
12738 
	- Fix for #474544. This is the second of two fixes required for this
12739 
problem. This fix creates a type 0 function which implements a "color cube"
12740 
for those tint transform functions which cannot be converted into a type 4
12741 
function. Customer #710. Note: There is one more revision planned for this
12742

This is an improvement from L. Peter Deutsch in the logic which tests the
12947 
size of the amount of data required for a function to be sampled. This
12948 
eliminates a possible math overflow and also tests for a negative size
12949 
value. This is part of bug 474544. (zfsample.c [1.2]: 2002/02/21 07:42:23

Adds support for compilation against a standard shared libjpeg. It is
13290 
believed that non-baseline compliant DCTEncoded data, permitted by early
13291 
versions of postscript, is now extremely rare and the prohibition against
13292 
SHARE_JPEG=1 may reasonably be removed. The autoconf build will prefer a
13293 
local copy of the jpeg source, in which case the D_MAX_BLOCKS_IN_MCU patch
13294 
will still be applied. If no such local copy is found, it will try to find a
13295 
shared library on the system. For all unix builds, if $(JSRCDIR)/jmemsys.h
13296 
cannot be found, we define DONT_HAVE_JMEMSYS_H and include our own versions
13297 
of the libjpeg memory manager prototypes. The default allocator in the
13298 
shared library is overridden by the ghostscript one at link-time. While this
13299 
may be implementation-dependent, it appears to function as desired on at
13300 
least GNU/Linux and Solaris. Also changes the autoconf build to prefer local
13301 
zlib and libpng source, and cleans up some variable names. (sjpegc.c [1.7]:

13336 
	- CIE color conversion could be very inaccurate if it didn't use
13337 
interpolation when cached sampled values were near zero. This fix detects
13338 
numerically sensitive areas and uses interpolation (which is computationally
13339 
expensive) only in those areas. Fixes SourceForge #465921. (gscie.c [1.6],

13349 
16-byte. (It may be that only jmpbuf structures actually need 16-byte
13350 
alignment, but gcc and glibc malloc align all objects that way.) Fixes

genarch.c. (gsmalloc.c [1.4], gxobj.h [1.3]: 2002/01/16 16:09:20 lpd)
13353 
	- pdfwrite incorrectly handled Metrics[2] and CDevProc by writing

Widths that differed from the widths in the underlying font. pdfwrite now

Fixes SourceForge #495414. (gxfont.h [1.6]: 2002/01/17 05:13:24 lpd)
13357 
	- The recent fix for #502866 required malloc to align blocks at
13358 
least as stringently as the compiler requires. Even though the ANSI C
13359 
specification appears to require this, and Ghostscript relies on it, Dan
13360 
reports that some C implementation doesn't do it. Additional patching to
13361 
deal with this problem will undoubtedly be required.... (gsmalloc.c [1.5]:

(gsmalloc.c [1.6]: 2002/01/18 18:27:08 lpd)
13365 
	- MSVC's malloc on x86 only aligns blocks mod 4, even though the
13366 
compiler aligns 'double' members of structures mod 8. Documents this fact in
13367 
the relevant places in the Ghostscript code, and removes the check that was
13368 
causing gsmalloc.c to produce warning messages. (gsmalloc.c [1.7],

13378 
	- When pdfwrite embedded a TrueType font with a generated format 6

Fixes problems:
13802 
	- the configure script was setting ZSRCDIR to the empty string in
13803 
the case where SHARE_ZLIB=1, causing a syntax error on the libpng command
13804 
line. It is now set to a harmless default (configure.ac [1.2]: 2002/01/06
13805 
00:12:03 giles)
13806 
	- prefer 'src' over '.' for the spurious local include line for
13807 
zlib. Thanks to Peter Deutsch for the suggestion. (configure.ac [1.3]:
13808 
2002/01/09 20:20:27 giles)
13809 
	- some files were missing the RCS 'Id' line with the last
13810 
modification date. partial fix for Sourceforge bug #500922. (gp_mac.h [1.2],
13811 
macsysstat.h [1.2], macsystypes.h [1.2], vms_x_fix.h [1.2]: 2002/01/09
13812 
21:04:21 giles)
13813 
	- corrects the name of the autoconf generated makefile for the
13814 
purpose of dependencies (Makefile.in [1.3]: 2002/02/01 04:11:46 giles)
13815 
	- Many files lacked double-inclusion protection, or implemented it
13816 
incorrectly. (gsdll.h [1.4], vms_x_fix.h [1.3]: 2002/02/20 01:32:47 lpd)
13817 
	- Fixes the gdevx.o command line in the case when AC_PATH_X sets
13818 
x_includes to the empty string. Fixes SF #530429. (Makefile.in [1.6],
13819 
configure.ac [1.7]: 2002/03/28 19:35:03 raph)
13820 
	- Uses a default 'src' setting for PSRCDIR in the autoconf build
13821 
with shared libpng, as we do with zlib, preventing compiler confusion from
13822 
empty -I lines. Partial fix for SF bug #514898. (configure.ac [1.8]:
13823 
2002/03/28 19:52:28 giles)
13824 
	- improves X11 path settings in the autoconf build. We use
13825 
AC_PATH_XTRA instead of the previous "is it null" hack with AC_PATH_X. The
13826 
new macro also defines some additional libraries that may need to be
13827 
included. We currently don't use this information. (Makefile.in [1.7],
13828 
configure.ac [1.9]: 2002/03/28 20:40:25 giles)
13829 
	- remove -fno-common from the standard gcc LDFLAGS. It is only
13830 
required at compile time and doesn't need to be passed to the linker.
13831 
(Makefile.in [1.8]: 2002/03/28 23:12:09 giles)
13832 
	- verify that our default collection of compiler switches
13833 
(gcc-specific) work before using them. This allows the autoconf build to
13834 
work with non-gcc compilers. Completes the fix for SF Bug #514898.
13835 
(Makefile.in [1.9], configure.ac [1.10]: 2002/03/28 23:15:53 giles)
13836 
	- remove -fno-common from the default LDFLAGS (again) This was
13837 
inadvertently reverted in the previous revision. (Makefile.in [1.10]:
13838 
2002/03/29 22:04:58 giles)
13839 
	- removes -Wtraditional for the default gcc compiler flags for the
13840 
autoconf build as well. (configure.ac [1.11]: 2002/03/29 22:05:54 giles)
13841 
	- removes gcc-specific compiler flags from the autoconf makefile,
13842 
including the -fomit-frame-pointer optimization. Replaces the workaround for
13843 
const not working in gcc 2.7 with the more general autoconf macro
13844 
AC_C_CONST. Lists the defines generated by the configure script for
13845 
reference in the Makefile, but doesn't make use of them.

(Makefile.in [1.11], configure.ac [1.12]: 2002/03/30 03:24:10 giles)
13847

13914 
which can't handle the new icon. (gswin.icx [1.1], gswin16.icx [1.1]:

13916 
 
13917 
Adds support for compilation against a standard shared libjpeg. It is
13918 
believed that non-baseline compliant DCTEncoded data, permitted by early
13919 
versions of postscript, is now extremely rare and the prohibition against
13920 
SHARE_JPEG=1 may reasonably be removed. The autoconf build will prefer a
13921 
local copy of the jpeg source, in which case the D_MAX_BLOCKS_IN_MCU patch
13922 
will still be applied. If no such local copy is found, it will try to find a
13923 
shared library on the system. For all unix builds, if $(JSRCDIR)/jmemsys.h
13924 
cannot be found, we define DONT_HAVE_JMEMSYS_H and include our own versions
13925 
of the libjpeg memory manager prototypes. The default allocator in the
13926 
shared library is overridden by the ghostscript one at link-time. While this
13927 
may be implementation-dependent, it appears to function as desired on at
13928 
least GNU/Linux and Solaris. Also changes the autoconf build to prefer local
13929 
zlib and libpng source, and cleans up some variable names.

13944 
 
13945 
<p>
13946 
This is a fully tested, stable release of Ghostscript. It fixes quite a
13947 
few issues with 7.02.
13948 
 
13949 
<p> Major changes include:
13950 
 
13951 
<ul>
13952 
<li>Integration of icclib 2.0.
13953 
 
13954 
<li>There was at least one embarassing pdfwrite bug, now fixed.
13955 
 
13956 
<li>Significant shading speedups, especially for worst-case files
13957 
such as Coons01.ps.
13958 
 
13959 
<li>The stdio logic is a lot more robust. 7.02 had some problems,
13960 
especially with trying to set stdin to non-blocking.
13961 
 
13962 
<li>The usual bug fixes. In particular, regression testing against
13963 
7.00 shows only one serious regression (nonsepqxd2distiller.pdf),
13964 
and numerous progressions.

Fixes problems:
14027 
	- cvs2hist no longer worked in Python 2.1 and later: the regex and
14028 
regsub modules were superseded by re, and append() no longer accepted
14029 
multiple arguments to create a tuple. The fixes are backward compatible for
14030 
all versions of Python from 1.5 on. (toolbin/cvs2hist.py [1.7]: 2001/09/23
14031 
04:45:10 lpd)
14032 
	- The previous update to make cvs2hist use Python's re module rather
14033 
than the obsolete regex and regsub modules didn't change the code to use
14034 
match objects when necessary. Finishes fixing SourceForge #462777.
14035 
(toolbin/cvs2hist.py [1.8]: 2001/09/23 20:43:16 lpd)
14036 
	- Some print statements for debugging were accidentally left in the
14037 
code. (toolbin/cvs2hist.py [1.9]: 2001/09/23 21:05:12 lpd)

14058 
	- Updates icclib to version 2.0, and integrates icclib changes. In
14059 
particular, icclib now accesses Ghostscript streams through the clean
14060 
icmFile object interface, rather than previous hack. Removes remnants of
14061 
previous hack, including gs_stdio.h header file and sread() and swrite()
14062

14121 
set the memory device width and height to zero to prevent drawing on it.
14122 
Always call the display_size callback to prevent a lockup in the caller, and

	- Fixes nontermination of triangle subdivision in shading, as
14234 
triggered by FTS 446-01.ps. The criterion for whether a triangle spans more
14235

<p>
14281 
This is a prerelease of Ghostscript, in preparation for a forthcoming
14282 
fully tested, supported 7.0x release. We are skipping the 7.01 release
14283 
number because that number is now associated with CVS versions.
14284 
 
14285 
<p> Major changes include:
14286 
 
14287 
<ul>
14288 
<li>Compile and portability fixes, including the dreaded time.h
14289 
problem that affects up-to-date Linux builds.
14290 
 
14291 
<li>Big improvements in stdio, including a new -sstdout= redirect
14292 
switch. In addition, reading from stdin uses nonblocking I/O, so the
14293 
ugly -_ workaround is no longer necessary.
14294 
 
14295 
<li>Substantial pdfwrite improvements.
14296 
 
14297 
<li>128-bit encrypted files are now supported.
14298 
 
14299 
<li>The usual bug fixes.
14300 
 
14301 
</ul>
14302 
 
14303 
Release issues that will be fixed before next fully supported version:
14304 
 
14305 
<ul>
14306 
 
14307 
<li> Update icclib to 2.0.
14308 
 
14309 
<li> Update hpijs and Omni glue to latest versions.
14310

subdivides fill region with trapezoid or rectangle subregions and then
14494 
paints each subregion with given color. If the color is shading, each
14495 
subregion to be subdivided into areas of constant color. But with radial
14496 
shading each area is a high order polygon, being subdivided into smaller
14497 
subregions, so as total number of subregions grows huge. Faster processing
14498 
is done here by changing the order of subdivision cycles : we first
14499 
subdivide the shading into areas of constant color, then apply the general
14500 
path filling algorithm (i.e. subdivide each area into trapezoids or
14501 
rectangles), using the filling path as clip mask. Source Forge bug #414022.

This file is a new utility intended for debug. It is not yet ready for prime
14573 
time, but is available for whoever wants to fix it. The main problems are:
14574 
1. It doesn't work for files that use chained filters such as [
14575 
/ASCII85Decode /FlateDecode ] 2. The PDF files that are written are
14576 
sometimes broken. GS gets an xref problem. This second problem may actually
14577 
due to lib/pdfwrite.ps since even when no conversion is done, the file is

The Unix shared object loader 'gsx' depends on Gtk+ which causes it to fail
14762 
in an environment where X11 and Gtk+ are not available. Add a console only
14763 
loader 'gsc' which does not depend on X11 or Gtk+. This does not support the
14764 
'display' device. Fixes sourceforge bug #450933. (dxmainc.c [1.1]:

When using the Unix Gtk+ loader gsx, delay setting the default color map and
14768 
visual until the display device is opened. This may allow gsx to be used

Fixes problems:
14847 
	- Empty pages included a Contents entry whose value was an empty
14848 
array: the spec allows this, and AR3 and 4 accept it, but AR5 rejects it.
14849 
(gdevpdf.c [1.34]: 2001/06/29 06:52:13 lpd)
14850 
	- When tiling with a bitmap, the /Type entry in the Pattern resource
14851 
was written twice. (Minor file size problem only, not a functional problem.)
14852 
(gdevpdfb.c [1.5]: 2001/06/29 17:04:17 lpd)
14853 
	- Some poorly designed PDF tools couldn't handle the fact that the
14854 
Contents stream of each page was not surrounded by q/Q. (The PDF spec does
14855 
not require this.) Fixes SourceForge bug #231390. (gdevpdfu.c [1.16]:
14856 
2001/07/02 18:07:55 lpd)
14857 
	- pdfwrite didn't set returned.current_char, so the "current
14858 
character" for kshow was 0 or a random value. Fixes SourceForge bug #420933.
14859 
(gdevpdfs.c [1.5]: 2001/07/02 19:09:23 lpd)
14860 
	- When producing text in a Type 3 (bitmap) font and using TL and '
14861 
for Y positioning, emitting a horizontal space character reset
14862 
text.use_leading, causing the line to be positioned incorrectly. Fixes

SourceForge bug #427159. (gdevpdft.c [1.33]: 2001/07/04 16:47:33 uid22160)
14864 
	- When producing text using a Type 3 (bitmap) font, the TL command
14865 
was used (incorrectly) when the new text position was directly below the
14866 
current text position, not (correctly) when the new text position was
14867

incorrect stroked width. (gdevpdfs.c [1.6]: 2001/07/04 21:57:02 uid22160)

(gdevpdfj.c [1.7], gdevpdfv.c [1.6]: 2001/07/07 19:15:51 lpd)

14879 
	- The algorithm for scaling down user coordinates to fall within
14880 
Acrobat Reader's limitations didn't work properly for stroked paths with
14881 
anisotropic CTMs, possibly producing large coordinates that led Acrobat (but
14882 
not Ghostscript) to display the resulting file incorrectly. Fixes

	- pdfwrite didn't write transfer functions in the output for images,
14886 
and allowed lossy compressions on images even in the presence of peculiar
14887 
transfer functions (such as functions simulating indexed color spaces). This
14888

14905 
fonts. (gdevpdfe.c [1.10]: 2001/07/31 06:32:42 lpd)
14906 
	- ICCBased color spaces were copied to the output even if the output

14908 
(gdevpdfc.c [1.16]: 2001/08/02 20:29:07 lpd)
14909 
	- If an image used a color space that couldn't be represented in
14910 
PDF, an invalid file was produced, rather than falling back to the default
14911 
representation as tiny rectangles. (bug introduced by H. Blischke's color
14912 
space fix) (gdevpdfi.c [1.24]: 2001/08/03 16:12:16 lpd)
14913 
	- Type 1 fonts that did not use the standard 1000-unit cell, such as
14914 
some fonts in PostScript files produced by Windows NT 4.0, were written with
14915 
an incorrect FontMatrix. (The output was visually correct, because the font
14916 
size was scaled to compensate.) Fixes SourceForge #439474.
14917

	- pdfwrite failed to recognize several of the standard screen spot
14929 
functions: Ellipse, Round, and Diamond weren't implemented, and several of
14930 
the others didn't match the PostScript implementation because of
14931 
float/double discrepancies. Also, pdfwrite wrote out halftone screens using
14932 
the adjusted ("actual") frequency and angle values rather than the requested
14933 
values. Fixes SourceForge #446676. (gdevpdfg.c [1.14]: 2001/09/22 16:27:04

	- This problem was a rangecheck error being reported in
15030 
.setindexedspace when the base colorspace was DeviceN. The cause was an
15031

	- EPS files without a showpage could not be viewed if given as a

	- This IdiomSet replaces 3 procedures generated by Win2K driver in
15073 
level 1 mode for RGB source image and DeviceRGB, DeviceCMYK, and DeviceGray
15074

15076 
replacement procedure uses indexed color space directly. This Idiom should
15077 
really be in a file in the IdiomSet directory of the Resource path, but we

	- pdfwrite didn't write transfer functions in the output for images,
15109 
and allowed lossy compressions on images even in the presence of peculiar
15110 
transfer functions (such as functions simulating indexed color spaces). This
15111 
fix writes transfer functions for images, prevents lossy compression if the
15112 
transfer function is not the identity, and undoes the hack that was

15115 
	- zfilelineedit sometimes reallocates (resizes) buffer string

	- If MaxLocalVM user parameter is set, perform garbage collection
15149

	- Prevent memory corruption when reading %statementedit. Allocate

lineedit buffer in correct memory space. Line being assembled is stored in a
15154 
PostScript string during callouts, so prevent zfilelineedit from reading
15155 
more than max_string_size bytes. Allocate extra space for trailing new-line

If an ICC color space failed to load, Acrobat Reader uses the alternate

Patch from Mr. Toshiya Suzuki : Implementing multi-dimensional CID ranges,
15192 
and fixing bugs about decoding text string with CID font : (1) when GS

consumes undefined byte sequence (which cannot be mapped to some glyphs), GS
15194 
aborts. (2) when selected CID font lacks the glyph for requested CID, GS
15195 
aborts. (3) "notdefrange" defines SINGLE CID for undefined byte sequences in
15196 
specified range, but current GS implementation take it as an offset to
15197 
calculate MULTIPLE CID. (4) "cidrange" operators accept only full range

	- Optimization for shading fill. The general path filling algorithm
15368 
subdivides fill region with trapezoid or rectangle subregions and then
15369 
paints each subregion with given color. If the color is shading, each
15370 
subregion to be subdivided into areas of constant color. But with radial
15371 
shading each area is a high order polygon, being subdivided into smaller
15372 
subregions, so as total number of subregions grows huge. Faster processing
15373 
is done here by changing the order of subdivision cycles : we first
15374 
subdivide the shading into areas of constant color, then apply the general
15375 
path filling algorithm (i.e. subdivide each area into trapezoids or

rectangles), using the filling path as clip mask. Source Forge bug #414022.
