BGI (Basic Graphical Instructions) to PostScript translator. Probably
|
|
|
3 |
not useful outside the Computer Centers. Added code to tie lines to
|
|
|
4 |
device space coordinates. Helps eliminate variations in line widths
|
|
|
5 |
noticeable when users selected a non-zero linewidth with the -w option.

Much that was omitted from early versions of the program has been
|
|
|
8 |
implemented. What's in place will handle most STARE (black and white)
|
|
|
9 |
and PRISM (color) BGI jobs. PRISM jobs often fill regions with color,
|
|
|
10 |
and need require device specific tuning to get things just right. An
|
|
|
11 |
easy solution is add "-P/prism true def" option to the postbgi command
|
|
|
12 |
line when you translate PRISM jobs.

A typical command line for STARE jobs would be,
|
|
|
15 |
|
|
|
16 |
postbgi file >file.ps
|
|
|
17 |
|
|
|
18 |
while for PRISM jobs use,
|
|
|
19 |
|
|
|
20 |
postbgi -P"/prism true def" file >file.ps
