/*
|
|
|
347 |
* Create the dictionary for an annotation or outline. For some
|
|
|
348 |
* unfathomable reason, PDF requires the following key substitutions
|
|
|
349 |
* relative to pdfmarks:
|
|
|
350 |
* In annotation and link dictionaries:
|
|
|
351 |
* /Action => /A, /Color => /C, /Title => /T
|
|
|
352 |
* In outline directionaries:
|
|
|
353 |
* /Action => /A, but *not* /Color or /Title
|
|
|
354 |
* In Action subdictionaries:
|
|
|
355 |
* /Dest => /D, /File => /F, /Subtype => /S
|
|
|
356 |
* and also the following substitutions:
|
|
|
357 |
* /Action /Launch /File xxx =>
|
|
|
358 |
* /A << /S /Launch /F xxx >>
|
|
|
359 |
* /Action /GoToR /File xxx /Dest yyy =>
|
|
|
360 |
* /A << /S /GoToR /F xxx /D yyy' >>
|
|
|
361 |
* /Action /Article /Dest yyy =>
|
|
|
362 |
* /A << /S /Thread /D yyy' >>
|
|
|
363 |
* /Action /GoTo => drop the Action key
|
|
|
364 |
* Also, \n in Contents strings must be replaced with \r.
|
|
|
365 |
* Also, an outline dictionary with no action, Dest, Page, or View has an
|
|
|
366 |
* implied GoTo action with Dest = [{ThisPage} /XYZ null null null].
|
|
|
367 |
* Note that for Thread actions, the Dest is not a real destination,
|
|
|
368 |
* and must not be processed as one.
|
|
|
369 |
*
|
|
|
370 |
* We always treat /A and /F as equivalent to /Action and /File
|
|
|
371 |
* respectively. The pdfmark and PDF documentation is so confused on the
|
|
|
372 |
* issue of when the long and short names should be used that we only give
|
|
|
373 |
* this a 50-50 chance of being right.
|
|
|
374 |
*
|
|
|
375 |
* Note that we must transform Rect and Border coordinates.
