Fixes problems: - Speed up shading type 1. (lib.mak [1.47]: 2001/04/05 08:32:28 igorm) Adds target to OS/2 makefile to build distribution zip archive. Disables multiple image windows for OS/2 because we can't tell when subsequent windows are closed. To allow multiple windows we would need to rewrite gspmdrv.c. (os2.mak [1.14]: 2001/04/01 10:13:24 ghostgum) Remove the bmpa*** devices from the default build. These are example devices to demonstrate async rendering but do not have any advantages to users over the bmp*** devices, and their inclusion requires thread support which is not available on all systems. Resolves SourceForge bug #213799. (unix-gcc.mak [1.15], unixansi.mak [1.11], unixtrad.mak [1.11]: 2001/04/03 20:04:46 rayjj) updates to support libpng v1.0.9.

(contrib.mak [1.23]: 2001/04/07 00:33:29 raph) Changes default XLIBDIR and XINCLUDE to /usr/X11R6, which is far more likely than the previous values. (contrib.mak [1.24], ugcclib.mak [1.12], unix-gcc.mak [1.18], unixtrad.mak [1.14]: 2001/04/07 06:50:27 raph) Updates version number and date in preparation for 6.64 release. Updates Develop.htm to accurately list source files. (version.mak [1.32]: 2001/04/07 07:55:25 raph)Utilities

Bugs #223896, #230699 (lib/ps2epsi [1.5], lib/ps2epsi.bat [1.4], lib/ps2epsi.cmd [1.2], lib/ps2epsi.ps [1.5]: 2001/04/04 04:45:42 alexcher) - The fileposition operator cannot be used on some data sources. Use .fileposition (if on Ghostscript) and make some other changes to make this portable to other PostScript interpreters. SourceForge bug #223005. (lib/image-qa.ps [1.3]: 2001/04/04 04:54:53 rayjj) - Previous fix had OutputFile set to a debug value. Restoring it to NUL (lib/ps2epsi.bat [1.5]: 2001/04/04 05:19:33 alexcher) - Adds whitespace to sed command in ps2epsi, needed on RH Linux 6.2. (lib/ps2epsi [1.6]: 2001/04/04 21:05:00 raph)Drivers
Fixes problems: - JPEG data made GC-traceable to prevent early freeing. Bug # 227090 gdevjpeg.c gdevpsdu.c sdeparam.c zfdctd.c zfdcte.c : JPEG control structure is allocated with a descriptor. sdct.h : defines descriptors for JPEG structures. sjpegc.c : implements the linked list of JPEG core blocks sjpegd.c sjpege.c : corrects the initialization order of (de)compress struct's gsstruct.h : yet another macro for a structure with 1 string and 1 ptr (gdevjpeg.c [1.3], gdevpsdu.c [1.10]: 2001/04/04 19:20:27 alexcher) Integrates patch from hpijs 0.94 so that Ghostscript can use hpijs drivers. (gdevhpij.c [1.1], gdevhpij.h [1.1]: 2001/04/07 00:33:29 raph)PDF writer
Fixes problems: - Emits W or W* after path construction operators when outputting clip paths in the pdfwrite driver, to be correct with respect to the PDF spec. (gdevpdfd.c [1.14]: 2001/04/07 07:12:52 raph)PDF Interpreter
Fixes problems: - The search area for %%EOF at the end of PDF file is increased to 4K to cover a file generated by Distiller 3.02b for AIX 4.1.1 Customer #580 (lib/pdf_main.ps [1.31]: 2001/04/07 01:34:23 alexcher) - A comment is corrected to match the source. (lib/pdf_main.ps [1.32]: 2001/04/07 01:47:00 alexcher) PDF 1.4 improvements: Fixes garbage collection of device filter stack. Forces idempotent path drawing in transparency mode. Corrects handling of Group at toplevel page. (lib/pdf_draw.ps [1.29], lib/pdf_main.ps [1.30]: 2001/04/06 22:23:44 raph)Interpreter
Fixes problems: - Windows poll function now returns a code to interrupt Ghostscript if the text window is closing. Don't show message box on exit if user closed the text window. (dwmain.c [1.4], dwtext.c [1.3]: 2001/04/03 11:12:58 ghostgum) - equality operation between a pointer and enum constant (with 0 value) is a syntax error on CodeWarrior. Replacing the enum with NULL. From Bernd Heller (zdscpars.c [1.10]: 2001/04/04 05:25:32 alexcher) - Register /All and /None in the name table on look-up. Otherwise an attempt to set the separation color space fails with /undefined (zcssepr.c [1.7]: 2001/04/04 16:09:15 alexcher) - JPEG data made GC-traceable to prevent early freeing. Bug # 227090 gdevjpeg.c gdevpsdu.c sdeparam.c zfdctd.c zfdcte.c : JPEG control structure is allocated with a descriptor. sdct.h : defines descriptors for JPEG structures. sjpegc.c : implements the linked list of JPEG core blocks sjpegd.c sjpege.c : corrects the initialization order of (de)compress struct's gsstruct.h : yet another macro for a structure with 1 string and 1 ptr (zfdctd.c [1.4], zfdcte.c [1.4]: 2001/04/04 19:20:27 alexcher) - Set default size of MAX_ESTACK to 5000. This is the minimal fix recommended by L. Peter Deutsch in the followup to SourceForge bug #224095. This should be fixed later to handle automatic stack expansion. The approaches are defined by Peter as #2 and #3. Interim resolution to SorceForge bug #224095. (interp.c [1.8]: 2001/04/06 06:42:45 rayjj) - Apparently Japanese Windows uses WM_USER+1 internally and conflicts with gswin32c messages starting from WM_USER+1. So gswin32c messages are moved to WM_USER+101 range. Fix from Akira Kakuto (dwmainc.c [1.4]: 2001/04/06 08:36:02 ghostgum) - Do not put Windows stdin into binary mode if it is the console because this returns CR and LF each time the Enter key is pressed. This caused Ghostscript to not pause at following showpage prompts. (dwmainc.c [1.5]: 2001/04/06 08:43:29 ghostgum) - Genoa FTS 035-07.ps got a SEGV error caused by data being allocated in non-GC memory, but pointer enumumeration giving these pointers to the GC for tracing. Since these objects didn't have GC type headers bad things happened. Also change one of the allocations in sjpegc.c to immovable that was not -- this change was not needed to prevent the crash. (zfdctd.c [1.5]: 2001/04/07 00:33:22 rayjj) - Compressed fonts are now recognized as narrow during font substitution. Customer #580 (lib/gs_fonts.ps [1.11]: 2001/04/07 01:07:01 alexcher) - two small issues with compilation under xlc on IBM AIX RS6000, a name conflict with structures names (u)int64, and trailing commas in enum declarations. Patch from Dan Coby. Sourceforge bug #414328. (dscparse.h [1.4]: 2001/04/07 07:28:33 giles) Adds target to OS/2 makefile to build distribution zip archive. Disables multiple image windows for OS/2 because we can't tell when subsequent windows are closed. To allow multiple windows we would need to rewrite gspmdrv.c. (dpmain.c [1.3]: 2001/04/01 10:13:24 ghostgum) updates to support libpng v1.0.10. OS/2 makefile fixup for v1.0.9 and above from Russell Lang.

Version 6.60 (2000-12-31)
This long-overdue fileset includes major new developer documentation, major improvements in the PDF writer (for embedded fonts and for DSC comments), and lots of bug fixes. Unfortunately, for unknown reasons, the release "smoke test" loops forever on the file data/ps/screen.ps -- but only when compiled in 'production' mode, not in 'debug' mode. We suspect a gcc bug, but don't have the time to track it down before the end of the millennium.

Incompatible changes
(Interpreter) - With WMode = 1, CID-keyed fonts with no Metrics2 now use default metrics computed from FontBBox rather than the horizontal metrics. (PDF interpreter) - The interpreter now skips to the next EOL after reading the data following the ID operator. - The incorrectly named ViewerOrientation DSC comment is now corrected to ViewingOrientation. (Streams) - All decoding filters that recognize an EOD in the source data must now have an init procedure that sets state->min_left = 1. (Library) - The glyph_data, subr_data, and seac_data procedures in a Type 1 font (gs_type1_data_procs), and the glyph_data procedure passed to psf_{check,get}_outline_glyphs, must now return 1 iff the outline string was newly allocated and should be freed by the caller, like the get_outline procedure of Type 42 fonts (gs_type42_data). - The ip_state structure is renamed ip_state_t, and has a new member, free_char_string. - The incorrectly named ViewerOrientation DSC comment is now corrected to ViewingOrientation, and the viewer_orientation members of the DSC parsing structure are corrected to viewing_orientation.Documentation
Fixes problems: - An isolated ampersand needed to be converted to the HTML form. (doc/Bug-form.htm [1.12]: 2000/11/04 17:53:57 lpd) - cvs2hist was generating invalid anchor names and not escaping special charaters. also enable '-r' commandline option, and pass '-b' if it's not specified for default branch logs only. Changes.htm now passes the validator. Minor url cleanup in Release.htm (doc/Changes.htm [1.19], doc/Release.htm [1.23]: 2000/11/10 01:52:35 giles) - Removes obsolete documentation reference to -DUsePrinterImages and clarifies the entry for the replacing -DPrinted. Fixes sourceforge bug # 121907. (doc/Use.htm [1.16]: 2000/11/20 20:34:23 giles) - Type 1 CharStrings loaded from disk for type 0 CIDFonts were never freed, except by garbage collection (which doesn't reclaim chunks with only a small amount of surviving data). In practice, this probably only affects the PDF writer. (doc/News.htm [1.71]: 2000/11/23 23:34:23 lpd) - The pswrite device couldn't write to pipes. The fix involved expanding the API for opening device OutputFiles so that the individual driver could specify whether it required, requested, or did not want a positionable file. Fixes SourceForge bug # 122223. (doc/Use.htm [1.17]: 2000/11/29 02:25:13 lpd) - The default ps2pdf "distiller parameters" weren't documented correctly; the parameter values for the other PDFSETTINGS (screen, printer, prepress) weren't documented at all; the xxxImageDownsampleThreshold parameters were incorrectly documented as xxxDownsampleThreshold. (doc/Ps2pdf.htm [1.22]: 2000/12/19 17:55:55 lpd) - The documentation of the -dSAFER command line switch was inaccurate.

Fixes problems: - cvs2hist was generating invalid anchor names and not escaping special charaters. also enable '-r' commandline option, and pass '-b' if it's not specified for default branch logs only. Changes.htm now passes the validator. Minor url cleanup in Release.htm (toolbin/cvs2hist.py [1.4]: 2000/11/10 01:52:35 giles) - The OS/2 platform code would no longer compile, because the stdio files are no longer available. (fix from rjl) (os2.mak [1.9]: 2000/12/05 01:16:26 lpd) - Embedded font subsets always used similar sequences of prefixes, making it likely that combining multiple PDF files would lead to clashes; the code now generates truly random prefixes, using an external source of random data. (devs.mak [1.39]: 2000/12/10 00:12:23 lpd) - Fixes a couple of dependency lists that had gotten out of sync. (devs.mak [1.40]: 2000/12/10 00:17:51 lpd) - Seek was broken and PDF interpreter failed when FILE_IMPLEMENTATION=fd The implementation of streams using direct OS calls is extended to support MSVC && Win32. close_.h is replaced by more general unistd_.h (lib.mak [1.40]: 2000/12/19 03:35:40 alexcher) - In the previous fix unistd__h was misspelt as unistd_h . (lib.mak [1.41]: 2000/12/19 05:35:53 alexcher) - The recent change for localized man pages didn't update 2 of the 3 top-level Unix makefiles. (unixansi.mak [1.7], unixtrad.mak [1.7]: 2000/12/23 16:29:53 lpd) - The list of doc files to be installed had gotten out of date (Develop.htm, Maintain.htm, and Ps-style.htm were missing). (unixinst.mak [1.16]: 2000/12/23 16:30:36 lpd) - unixinst.mak was checked in with the previous fix only partly done. (unixinst.mak [1.17]: 2000/12/23 16:34:12 lpd) Collect some stray configuration related externs into iconf.h (int.mak [1.40]: 2000/11/04 06:12:02 rayjj) Adds DSC parsing capability to the PostScript interpreter, with an optional 'feature' to use the DSC Orientation comments to compensate for sloppy PostScript producers that don't emit an appropriate setpagedevice command. (int.mak [1.41]: 2000/11/05 18:33:53 lpd) Adds the 'hook' for passing DSC comments to the PDF writer, but doesn't actually process any of the comments. NOTE: Part of this code was accidentally included in the recent fix for local/global VM problems in the PostScript code for using the DSC parser. (devs.mak [1.36]: 2000/11/07 18:54:26 lpd) Reorganizes some text-writing code in anticipation of adding CIDFont and CMap support. (devs.mak [1.37]: 2000/11/17 22:11:44 lpd) Avoids exporting empty LD_RUN_PATH environment variable to the link process. This was causing binaries to search the current directory for libraries, which was a security hole. Fixes SourceForge bug 122532. (ugcclib.mak [1.6], unixlink.mak [1.3]: 2000/11/28 00:14:48 raph) Updates the date and version checker for compatibility with the newest documentation standards; also makes it check the makefile values of JVERSION and PVERSION against the currently installed third-party source code. (toolbin/pre [1.9]: 2000/12/05 21:14:14 lpd) Extensively revises and updates the pdfwrite text handling code to support processing and embedding of all types of fonts (except for Type 3 and CIDFontType 1, which are defined by PostScript procedures), and all variants of 'show' (including kshow and glyphshow). In particular, Type 0 fonts with all FMapTypes (including CMap-based), CIDFontType 0 and 2 fonts, and both standard and non-standard CMaps are supported. (devs.mak [1.38], int.mak [1.42], lib.mak [1.38]: 2000/12/08 23:35:37 lpd) removes a spurious import of the cgi module (toolbin/cvs2hist.py [1.5]: 2000/12/11 19:40:23 giles) Splits off the code for downsampling an oversampled character bitmap into a separate file. (lib.mak [1.39]: 2000/12/14 00:14:52 lpd) Adds a '-t' option to enable text output rather than html, replacing the old behavior, which was to return text unless a version string was passed with '-v'. The version string is now set to 'CVS' if no explicit version is passed, and this is used in the named anchors within the html output. (toolbin/cvs2hist.py [1.6]: 2000/12/23 09:38:10 giles) Adds support for localized manpages to the make 'install' target. On unix the makefile will now intall any files with the $MAN1EXT extension it finds under locale subdirs of the man directory that are listed in the MAN_LCDIRS variable. The $man1dir is correspondingly removed from unix-gcc.mak. Also adds separate targets: install-doc install-man install-examples install-libdata (unix-gcc.mak [1.9], unixinst.mak [1.15]: 2000/12/23 10:10:37 giles) Improves the set of files checked by hrefcov +lib. (toolbin/hrefcov.tcl [1.5]: 2000/12/29 02:16:13 lpd) Adds a script for batch-converting PostScript files to PDF, intended to be useful for testing. (toolbin/many2pdf.tcl [1.1]: 2000/12/31 22:28:09 lpd) Updates repository for 6.60 release. (toolbin/pre [1.10], version.mak [1.24]: 2001/01/01 00:24:06 lpd)Utilities
Fixes problems: - pdfopt.ps used the "unresolved?" procedure from pdf_base.ps, which has been replaced by the slightly different "resolved?" procedure. (lib/pdfopt.ps [1.4]: 2000/12/01 04:15:52 lpd) - The OS/2 platform code would no longer compile, because the stdio files are no longer available. (fix from rjl) (gp_os2.c [1.5]: 2000/12/05 01:16:26 lpd) - File flush method uses file member in stream. On Windows and OS/2 it is NULL for %stdout or %stderr. So the standard flush method is installed. (gp_msio.c [1.3], gp_os2.c [1.6]: 2000/12/19 03:44:24 alexcher) - /NullEncode filter no longer supports fileposition. Replacing fileposition with .fileposition (lib/impath.ps [1.3]: 2000/12/28 17:06:07 alexcher) - _.at file was not deleted in BAT file; SAFER option added to CMD file. (lib/eps2eps.bat [1.4], lib/eps2eps.cmd [1.2]: 2000/12/30 18:45:37 alexcher) Improves documentation of cid2code.ps by adding a complete usage example. (lib/cid2code.ps [1.3]: 2000/11/30 18:22:11 lpd) Adds extensive documentation to genconf.c; also brings it into line with current Ghostscript coding standards. (genconf.c [1.4]: 2000/12/20 04:20:34 lpd) Safe mode implemented using DELAYSAFER flag. (lib/pdf2dsc [1.3], lib/pdf2dsc.bat [1.1], lib/pdf2dsc.ps [1.3]: 2000/12/29 05:03:49 alexcher)Drivers
Fixes problems: - In PDF output, color values of 1.0 were usually written as 0.999. (bug introduced in version 6.22) (gdevpsdu.c [1.8]: 2000/11/12 07:13:26 lpd) - The pswrite device couldn't write to pipes. The fix involved expanding the API for opening device OutputFiles so that the individual driver could specify whether it required, requested, or did not want a positionable file. Fixes SourceForge bug # 122223. (gdevps.c [1.13], gdevpx.c [1.5]: 2000/11/29 02:25:13 lpd) - Invalid (uninitialized) StripByteCount was being left in file for the tiff12nc and tiff24nc devices. Needed to call gdev_tiff_end_strip(). (gdevtfnx.c [1.4]: 2000/12/15 06:09:27 rayjj) - Fixes bug introduced in gdevxini.c revision 1.5. Don't overwrite the pixmap handle provided in the GHOSTVIEW environment variable. (gdevxini.c [1.10]: 2000/12/15 10:18:47 ghostgum) - The pswrite device produced an extra page if the transfer function didn't map "1 setgray" to device white. (gdevps.c [1.14]: 2000/12/21 03:58:54 lpd)PDF writer
Fixes problems: - kshow caused the PDF writer to revert to bitmapped fonts. Fixes SourceForge bug # 104118. (gdevpdft.c [1.21]: 2000/11/06 04:17:14 lpd) - The PDF writer didn't handle stroked fonts correctly (they were filled instead of stroked). (gdevpdf.c [1.23], gdevpdfd.c [1.11], gdevpdft.c [1.22], gdevpdfx.h [1.23]: 2000/11/12 06:52:08 lpd) - When mixing filled and stroked fonts, the color wasn't set correctly. (gdevpdft.c [1.23]: 2000/11/12 07:14:30 lpd) - The PDF writer incorrectly assumed that in PDF 1.3, the standard Latin character set was the PostScript 3 extended set (it's actually the old PostScript Level 2 set). (gdevpdft.c [1.28]: 2000/11/20 18:13:55 lpd) - Embedded CIDFontType 2 fonts had an incorrect BoundingBox. (gdevpdff.c [1.14]: 2000/12/09 06:53:25 lpd) - Embedded font subsets always used similar sequences of prefixes, making it likely that combining multiple PDF files would lead to clashes; the code now generates truly random prefixes, using an external source of random data. (gdevpdf.c [1.26], gdevpdfe.c [1.8], gdevpdff.c [1.15], gdevpdff.h [1.9], gdevpdfx.h [1.27]: 2000/12/10 00:12:23 lpd) - Non-embedded Multiple Master instances weren't identified as such (font Subtype = /MMType1). (gdevpdfw.c [1.7]: 2000/12/11 08:52:01 lpd) - pdfwrite would crash if a bitmap character was larger than 10Kb (compressed). The fix simply raises the limit to 1 Mb. (gdevpdft.c [1.30]: 2000/12/13 01:33:37 lpd) - When processing DSC comments, some constant strings weren't copied to the heap, possibly causing memory access errors. (gdevpdfp.c [1.16]: 2000/12/16 07:02:35 lpd) - If the same standard (base 14) font was loaded more than once (because of save/restore), the PDF file could contain fonts that had suffixed names (e.g., Helvetica~2) but with data missing as though they were standard fonts, upsetting Acrobat Reader. Fixes SourceForge bug # 101905. THIS FIX IS IN A VERY FRAGILE AREA AND MAY INTRODUCE NEW PROBLEMS. (gdevpdff.c [1.16]: 2000/12/16 08:00:53 lpd) - The previous fix for copying DSC comment keys to the heap was unnecessarily complex. (gdevpdfp.c [1.17]: 2000/12/16 19:28:51 lpd) - Resource usage wasn't tracked separately for Form XObjects (BP/EP pdfmarks), producing non-compliant files that caused errors from Acrobat. Fixes SourceForge bug # 102146. (gdevpdf.c [1.28], gdevpdff.c [1.17], gdevpdff.h [1.10], gdevpdfm.c [1.8], gdevpdfo.c [1.6], gdevpdfo.h [1.6], gdevpdft.c [1.31], gdevpdfu.c [1.14], gdevpdfw.c [1.8], gdevpdfx.h [1.28]: 2000/12/16 19:36:32 lpd) - Strict type correctness is required on VMS system. Contributed by Jouk Jansen joukj@hrem.stm.tudelft.nl (gdevpdfw.c [1.9]: 2000/12/18 21:58:03 alexcher) Adds the 'hook' for passing DSC comments to the PDF writer, but doesn't actually process any of the comments. NOTE: Part of this code was accidentally included in the recent fix for local/global VM problems in the PostScript code for using the DSC parser. (gdevpdfp.c [1.13]: 2000/11/07 18:54:26 lpd) Changes the internal indication of whether to allow font subsetting from a Boolean to OK, YES, NO. (Unfortunately, I no longer remember why this change is needed.) (gdevpdfe.c [1.6], gdevpdff.c [1.10], gdevpdff.h [1.5], gdevpdft.c [1.24]: 2000/11/14 06:57:21 lpd) When writing PDF output, adds the ability to convert text in Type 0 fonts to text in the descendant leaf fonts. This completes the handling of text output except for CID-keyed fonts. (gdevpdft.c [1.25]: 2000/11/14 16:47:09 lpd) Reorganizes some text-writing code in anticipation of adding CIDFont and CMap support. (gdevpdff.c [1.11], gdevpdff.h [1.6], gdevpdft.c [1.26]: 2000/11/17 22:11:44 lpd) Makes glyphshow no longer revert to bitmapped fonts. Also adds a CIDFont pseudo-resource, in anticipation of adding CID-keyed font support. (gdevpdff.c [1.12], gdevpdff.h [1.7], gdevpdft.c [1.27], gdevpdfx.h [1.24]: 2000/11/20 08:31:20 lpd) Extensively revises and updates the pdfwrite text handling code to support processing and embedding of all types of fonts (except for Type 3 and CIDFontType 1, which are defined by PostScript procedures), and all variants of 'show' (including kshow and glyphshow). In particular, Type 0 fonts with all FMapTypes (including CMap-based), CIDFontType 0 and 2 fonts, and both standard and non-standard CMaps are supported. (gdevpdf.c [1.24], gdevpdfe.c [1.7], gdevpdff.c [1.13], gdevpdff.h [1.8], gdevpdfs.c [1.1], gdevpdft.c [1.29], gdevpdfu.c [1.13], gdevpdfw.c [1.6], gdevpdfx.h [1.25]: 2000/12/08 23:35:38 lpd) If ParseDSCCommentsForDocInfo is set to true, copies information from DSC comments Creator, CreationDate, For, and Title into the output's Info dictionary. (gdevpdfp.c [1.14]: 2000/12/09 07:49:22 lpd) Makes the PDF writer extract orientation and bounding box information from DSC comments, if present. The orientation is used to set Rotate if AutoRotatePages is not selected; the bounding box is not yet used for anything. (gdevpdf.c [1.25], gdevpdfp.c [1.15], gdevpdfx.h [1.26]: 2000/12/09 19:54:54 lpd) Slightly changes the initialization of the random offset for font subset prefixes, to work better with low-resolution clocks such as those typical on PCs. (gdevpdf.c [1.27]: 2000/12/16 19:31:10 lpd)PDF Interpreter
Fixes problems: - Type 0 fonts with a non-standard (embedded) CMap didn't work at all. (lib/pdf_font.ps [1.15]: 2000/12/02 20:41:52 lpd) - The PDF interpreter ignored the CIDToGIDMap entry in (embedded) CIDFontType 2 fonts, producing incorrect output if the map wasn't /Identity. (lib/pdf_font.ps [1.16]: 2000/12/07 23:41:10 lpd) - GS didn't dereference indirect objects in Widths array. (lib/pdf_font.ps [1.17]: 2000/12/17 19:06:19 alexcher) - Fixes a slight oversight in the true/false/null improvement for the PDF interpreter. (lib/pdf_base.ps [1.12]: 2000/12/26 04:10:12 lpd) - When a non-TrueType font was substituted for a TrueType font, the Encoding in the font descriptor was ignored. This hack was intended to fix SF bug # 104702, an invalid PDF file, but it broke another case. Removal of the hack makes GS render both cases similar to AR 4. (lib/pdf_font.ps [1.18]: 2000/12/26 04:29:30 alexcher) - The PDF interpreter didn't rotate the CropBox for landscape pages, producing incorrect output if the input of ps2pdf was a landscape PDF file. (lib/pdf_main.ps [1.26]: 2000/12/31 01:07:18 lpd) Improves font substitution by taking the "Narrow" property into account. Fixes SourceForge bug 116460. Fix due to Leon Bottou. (lib/pdf_font.ps [1.13]: 2000/11/05 17:36:28 raph) Wraps the showpagecontents call in gsave/grestore, so that the graphics state for drawing annotations is pristine. Fixes Sourceforge bug 123310. (lib/pdf_main.ps [1.23]: 2000/11/25 22:00:21 raph) The published PDF specification says the Encoding name "must be" one of the 3 predefined Encodings, implying that an error should occur if it isn't. However, Acrobat Reader simply ignores unknown names, and since there are some buggy applications that rely on this, we do the same. (lib/pdf_font.ps [1.14]: 2000/11/28 18:55:24 alexcher) The PDF specification says that the 'xref' must be on a line by itself. The code formerly used readline and linene to check this. However, Acrobat Reader only requires the line to begin with 'xref', and there are enough applications producing non-compliant PDF files that we have to do this too. (lib/pdf_main.ps [1.24]: 2000/12/18 03:41:35 alexcher) AI8 writes bogus encoding array [0 1 0 0 0 0 0 0] AR doesn't care. So we have to straighten it up here. (lib/pdf_draw.ps [1.24]: 2000/12/20 19:02:24 alexcher) Makes the PDF interpreter handle true, false, and null specially, rather than by dictionary lookup, so that the PostScript interpreter can still process these names using the special fast case for names defined only in systemdict. (lib/pdf_base.ps [1.11], lib/pdf_main.ps [1.25]: 2000/12/26 04:08:44 lpd)Interpreter
Fixes problems: - The recently updated code for activating the DSC comment parser had several local/global VM problems, causing invalidaccess errors. (lib/gs_dps2.ps [1.3], lib/gs_init.ps [1.27], lib/gs_pdfwr.ps [1.7]: 2000/11/07 18:51:24 lpd) - There was still a bug in the code for passing DSC comments to the PDF writer, causing typecheck errors. (lib/gs_pdfwr.ps [1.8]: 2000/11/07 19:27:14 lpd) - If the procedure of a FunctionType 4 Function was syntactically valid but exceeded the maximum stack depth, an attempt was made to free a string as an object, causing memory corruption. (zfunc4.c [1.6]: 2000/11/11 17:34:06 lpd) - Disk-based TrueType fonts caused a memory leak. (Currently, there are no such fonts, but CIDFontType 2 fonts, and directly-accessed TrueType fonts, should be made disk-based.) (zfcid1.c [1.4]: 2000/11/22 08:32:07 lpd) - Type 1 CharStrings loaded from disk for type 0 CIDFonts were never freed, except by garbage collection (which doesn't reclaim chunks with only a small amount of surviving data). In practice, this probably only affects the PDF writer. (zfcid0.c [1.5]: 2000/11/23 23:34:22 lpd) - Single-byte notdef ranges in CMaps incorrectly incremented the CID number, rather than assigning the same CID to all characters in the range. (lib/gs_cmap.ps [1.9]: 2000/11/29 06:58:36 lpd) - In dictionaries, an int lookup key sometimes didn't match a real stored key, and vice versa. Fixes SourceForge bug # 123678. (idict.c [1.3]: 2000/11/30 07:13:08 lpd) - Further tweaking of the logic to clear end_status flags in a pipeline in the continuation of a procedure write, making it more aggressive than the previous fix, but less aggressive than the original code. This is a revised fix for Sourceforge bug 119777. (zfproc.c [1.7]: 2000/12/02 19:58:45 raph) - 'gstate' was allowed in global VM even if the current graphics state included references to structures in local VM (which is, in fact, normally the case) and the save level was non-zero: this could create a dangling pointer after the 'restore'. This "fix" is a workaround that simply prohibits doing this, but a correct fix would copy any such structures. (zdps1.c [1.3]: 2000/12/02 20:39:37 lpd) - The first call of check_psc_function in gs_build_function_4 didn't initialize size to 0, causing the computed value of size to be garbage, possibly leading to a VMerror or memory corruption. (zfunc4.c [1.7]: 2000/12/03 16:56:31 alexcher) - The font_info procedure for PostScript fonts other than Type 1 didn't return information from the FontInfo dictionary (Copyright, FamilyName, FullName, Notice), causing this information to be omitted when embedding the font in a PDF file. (ifont.h [1.6], zbfont.c [1.7], zfont.c [1.3], zfont1.c [1.9]: 2000/12/03 23:35:30 lpd) - The %%ViewingOrientation: DSC comment was misspelled %%ViewerOrientation:. This also corrects the CDSC_VIEWINGORIENTATION enum value (formerly CDSC_VIEWERORIENTATION, and the viewing_orientation members of the CDSCPAGE structure and the CDSC structure (formerly viewer_orientation). (dscparse.c [1.3], dscparse.h [1.3], zdscpars.c [1.8]: 2000/12/09 18:28:23 lpd) - Unitialized member of CDSCPAGE caused random crashes. (dscparse.c [1.4]: 2000/12/13 07:18:46 alexcher) - systemdict was being created too small for LanguageLevel 3 systems. (It expanded properly, but left a sandbar.) (iinit.c [1.3]: 2000/12/26 04:25:54 lpd) - Expanding a permanent dictionary (systemdict or userdict) destroyed the single-definition bookkeeping for names defined in that dictionary, slowing down subsequent interpretation. (idict.c [1.4]: 2000/12/26 06:09:58 lpd) - Fix to dscparse.c for parsing DOS EPS files. Code now looks for %!PS-Adobe- at the start of the PostScript section, not at the start of the DOS EPS header. (dscparse.c [1.5]: 2000/12/28 01:45:01 ghostgum) Collect some stray configuration related externs into iconf.h (imain.c [1.3], imainarg.c [1.5]: 2000/11/04 06:12:02 rayjj) branches: 1.1.2; Collect some stray configuration related externs into iconf.h (iconf.h [1.1]: 2000/11/04 06:12:02 rayjj) Add COMPILE_INITS information line to -h help output. (imainarg.c [1.6]: 2000/11/04 06:13:42 rayjj) Adds DSC parsing capability to the PostScript interpreter, with an optional 'feature' to use the DSC Orientation comments to compensate for sloppy PostScript producers that don't emit an appropriate setpagedevice command. (lib/gs_dscp.ps [1.1], zdscpars.c [1.1]: 2000/11/05 18:33:52 lpd) branches: 1.1.2; Adds DSC parsing capability to the PostScript interpreter, with an optional 'feature' to use the DSC Orientation comments to compensate for sloppy PostScript producers that don't emit an appropriate setpagedevice command. (dscparse.c [1.1], dscparse.h [1.1]: 2000/11/05 18:33:53 lpd) Polishes the DSC parser interface: improves comments and formatting, and fixes a couple of very minor glitches. (zdscpars.c [1.2]: 2000/11/06 07:34:21 lpd) branches: 1.3.2; ... and fixes an overlooked const discrepancy. (zdscpars.c [1.3]: 2000/11/06 07:35:51 lpd) branches: 1.2.2; Fix: The recently updated code for activating the DSC comment parser had several local/global VM problems, causing invalidaccess errors. (lib/gs_dscp.ps [1.2]: 2000/11/07 18:51:25 lpd) Return code variables (code and comment_code) in zparse_dsc_comments(). need to be signed. (zdscpars.c [1.4]: 2000/11/08 00:54:48 dancoby) Rewrites .parse_dsc_comment to use the parameter list machinery, removing a little functionally duplicated code; changes two incorrect uints to ints (fix from dan@artifex.com); adds additional comment types (BoundingBox, PageBoundingBox, BeginDefaults, EndDefaults) to the interface. (zdscpars.c [1.5]: 2000/11/08 07:07:32 lpd) DSC parser changes: adds %%ViewerOrientation to DSC parser; doesn't flag an error if %%Pages is absent but one %%Page is found; frees memory if initialization fails; recognizes general whitespace in some places where only spaces were recognized before. (changes from gsview@ghostgum.com.au) (dscparse.c [1.2], dscparse.h [1.2]: 2000/11/13 05:44:58 lpd) Adds DSC comment tracing to ps2pdf, if -dDEBUG is specified on the command line. (lib/gs_pdfwr.ps [1.9]: 2000/11/13 17:03:51 lpd) Adds %%EndDefaults, %%For:, and %%ViewerOrientation: to the set of DSC comments handled by the .parse_dsc_comments operator. (zdscpars.c [1.6]: 2000/11/13 17:06:18 lpd) Slightly simplifies the code for creating the internal representation of CMaps. (lib/gs_cmap.ps [1.8]: 2000/11/16 00:32:00 lpd) Changes .buildshading to always apply a ReusableStreamDecode filter to file and stream DataSources, so that multiple passes over the stream work. This patch closes SourceForge bug 121810. (lib/gs_ll3.ps [1.7]: 2000/11/16 00:37:32 raph) Makes single-byte CMap ranges convert into a single range in the internal representation, rather than (largest - smallest + 1) separate single-element ranges. (lib/gs_cmap.ps [1.10]: 2000/11/29 07:10:27 lpd) Adds documentation for the procedures declared in ifont.h. (ifont.h [1.5]: 2000/12/03 23:14:28 lpd) Extensively revises and updates the pdfwrite text handling code to support processing and embedding of all types of fonts (except for Type 3 and CIDFontType 1, which are defined by PostScript procedures), and all variants of 'show' (including kshow and glyphshow). In particular, Type 0 fonts with all FMapTypes (including CMap-based), CIDFontType 0 and 2 fonts, and both standard and non-standard CMaps are supported. (lib/gs_cidfn.ps [1.18]: 2000/12/08 23:35:38 lpd) Makes the default value of ParseDSCCommentsForDocInfo true rather than false. (lib/gs_pdfwr.ps [1.10]: 2000/12/09 08:00:52 lpd) Changes the parsing of the DSC Orientation comments to return -1 .. 3 rather than 0 or 1. (lib/gs_dscp.ps [1.3], zdscpars.c [1.7]: 2000/12/09 17:52:29 lpd) Changes .parse_dsc_comments to distinguish (document default) ViewingOrientation from PageViewingOrientation, as for [Page]Orientation. (zdscpars.c [1.9]: 2000/12/09 19:52:49 lpd) Updates the comments with a new proposal for speeding up name lookup in the interpreter. (dstack.h [1.3]: 2000/12/26 01:20:58 lpd) The old code caused gswin crash when console window closes. (dwimg.cpp [1.3]: 2000/12/26 13:41:40 igorm) New flag DELAYSAFER added to defer activation of safety checks. SAFER=false => no safety checks SAFER=true, DELAYSAFER=false => safety checks always SAFER=true, DELAYSAFER=true => safety checks after .setsafe (lib/gs_init.ps [1.28]: 2000/12/29 04:13:56 alexcher)Streams
Fixes problems: - Seek was broken and PDF interpreter failed when FILE_IMPLEMENTATION=fd The implementation of streams using direct OS calls is extended to support MSVC && Win32. close_.h is replaced by more general unistd_.h (sfxfd.c [1.6]: 2000/12/19 03:35:40 alexcher)Library
Fixes problems: - Several places in the band list code didn't call s_init_state to initialize locally allocated stream states: this is now required (see the "Incompatible changes" section above). We suspect there are a few more places that will need this fix. (gxclbits.c [1.3], gxcldev.h [1.4], gxclread.c [1.3], gxclutil.c [1.3]: 2000/11/05 00:34:24 lpd) - Fixes infinite loops when writing large bitmaps into clist. Now, cmd_put_bits never requests an allocation in the clist buffer larger than cbuf_size. (gxclbits.c [1.4]: 2000/11/05 18:44:57 raph) - Works around an Acrobat Reader 4 bug that causes AR4 to draw a single pixel, rather than nothing, when filling a subpath consisting only of a moveto. (gdevvec.c [1.8]: 2000/11/07 16:42:28 lpd) - The PDF writer didn't handle stroked fonts correctly (they were filled instead of stroked). (gdevvec.c [1.9], gdevvec.h [1.5]: 2000/11/12 06:52:08 lpd) - The pdfwrite and pswrite drivers could emit a lineto or rlineto without a moveto at the beginning of the path. (bug introduced very recently, by a workaround for an Acrobat Reader bug) (gdevvec.c [1.10]: 2000/11/14 07:41:08 lpd) - Attempting to write a CFF Type 2 font larger than 32K but smaller than 64K caused a rangecheck. (gdevpsf2.c [1.8]: 2000/11/19 17:48:08 lpd) - Computing the default width or the fixed width for a CIDFont or TrueType font could do a huge amount of unnecessary work. (Probably only affects the PDF writer.) (gsfont.c [1.3]: 2000/11/20 21:09:09 lpd) - The Type 1 to Type 2 CharString converter (currently used only by the PDF writer) often didn't detect invalid CharStrings as input. (gdevpsfx.c [1.6]: 2000/11/21 02:33:55 lpd) - The code for writing a CIDFontType0 CFF font mistook Type 2 CharStrings for Type 1, and tried to convert them to Type 2. (This currently affects only the PDF writer.) (gdevpsf2.c [1.9]: 2000/11/21 02:35:59 lpd) - Disk-based TrueType fonts caused a memory leak. (Currently, there are no such fonts, but CIDFontType 2 fonts, and directly-accessed TrueType fonts, should be made disk-based.) (gdevpsft.c [1.5], gstype42.c [1.10]: 2000/11/22 08:32:07 lpd) - Type 1 CharStrings loaded from disk for type 0 CIDFonts were never freed, except by garbage collection (which doesn't reclaim chunks with only a small amount of surviving data). In practice, this probably only affects the PDF writer. (gsfcid.c [1.5], gstype1.c [1.6], gstype2.c [1.9], gxfont1.h [1.5], gxtype1.c [1.8], gxtype1.h [1.5]: 2000/11/23 23:34:22 lpd) - The pswrite device couldn't write to pipes. The fix involved expanding the API for opening device OutputFiles so that the individual driver could specify whether it required, requested, or did not want a positionable file. Fixes SourceForge bug # 122223. (gdevpipe.c [1.4], gdevvec.c [1.11], gdevvec.h [1.6], gsdevice.c [1.8]: 2000/11/29 02:25:13 lpd) - The change for freeing transient CharStrings introduced two bugs, possibly causing the code to free data twice, or to free data that should be retained. (gdevpsfx.c [1.8]: 2000/11/30 05:58:19 lpd) - Allocates graphics state path in stable memory. This prevents paths in Type 3 fonts allocated inside a save ... setcachedevice ... restore sequence from being prematurely freed. Fixes SourceForge bug 101549. (gspath1.c [1.3], gsstate.c [1.6]: 2000/12/04 21:13:55 raph) - An inadvertent change caused the graphics state not to be freed on grestore. This fix, due to lpd, restores the freeing statement. (gsstate.c [1.7]: 2000/12/05 09:24:57 raph) - The pointers to the substituted color spaces in the graphics state weren't included in the structure descriptor, causing memory access errors if UseCIEColor was used. (gsstate.c [1.8]: 2000/12/11 04:06:22 alexcher) - In TrueType fonts, glyph outlines starting with an off-curve point didn't render correctly, replacing the curve with a pair of straight lines. (gstype42.c [1.11]: 2000/12/12 22:27:56 alexcher) - Strict type correctness is required on VMS system. Contributed by Jouk Jansen joukj@hrem.stm.tudelft.nl (gdevpsf2.c [1.12], gsfcmap.c [1.13]: 2000/12/18 21:58:03 alexcher) - Seek was broken and PDF interpreter failed when FILE_IMPLEMENTATION=fd The implementation of streams using direct OS calls is extended to support MSVC && Win32. close_.h is replaced by more general unistd_.h (gpmisc.c [1.9]: 2000/12/19 03:35:40 alexcher) - Fixes a subtle logic bug in the scan line path filling code, which unfortunately involved rewriting the code from scratch. The new code is also somewhat subtle, and may contain new bugs: DON'T TRUST IT YET. Fixes SourceForge bug # 117066. (gxfill.c [1.7]: 2000/12/23 06:02:39 lpd) - Embedded Type 1 fonts omitted StdVW. (Acrobat Reader requires this, even though the Type 1 specification says it is optional.) (gdevpsf1.c [1.8]: 2000/12/29 01:18:55 lpd) Adds developer documentation on the color mapping pipeline. (gxfrac.h [1.3]: 2000/11/03 04:53:00 lpd) Improves the documentation of the minimum responsibilities of the 'process' procedure in a text enumerator. (gxtext.h [1.6]: 2000/11/06 00:44:37 lpd) Adds a param_string_from_transient_string macro, to parallel param_string_from_string for non-permanent C strings. (gsparam.h [1.8]: 2000/11/08 06:56:50 lpd) Adds a macro for declaring suffix subclasses with 5 added pointers (in addition to the existing 1, 2, 3, 4, and 6). (gsstruct.h [1.6]: 2000/11/21 16:46:55 lpd) Adds a procedure for testing whether a glyph is a "notdef" in a font, necessary for fixing a memory consumption problem when accessing type 0 CIDFonts. (gsfont.c [1.4], gxfont.h [1.3]: 2000/11/23 23:23:40 lpd) Speeds up the slow case of fixed_mult_quo by nearly a factor of 2, by using a tiny bit of numerical analysis. (gsmisc.c [1.9], gxfixed.h [1.3]: 2000/11/24 06:53:23 lpd) Improves the performance of embedded font writing by freeing strings when no longer needed, and by removing redundant computation. (Currently relevant only to the PDF writer.) (gdevpsf1.c [1.7], gdevpsf2.c [1.10], gdevpsfu.c [1.5], gdevpsfx.c [1.7]: 2000/11/24 07:10:41 lpd) Adds a procedure for creating an Identity CMap, needed by the PDF writer. (gsfcmap.c [1.11], gxfcmap.h [1.6]: 2000/11/26 04:08:41 lpd) Implements the stopgap measure of increasing fill_adjust for Coons patch shading, to cover the dropouts caused by incorrect triangulation of the mesh surface. See SourceForge Bug 119588 for a more thorough analysis. (gsptype2.c [1.4], gxshade4.c [1.4]: 2000/11/29 01:31:30 raph) Adds an internal unique ID to CMap structures (gs_cmap_t), for use as a cache or comparison key. (gsfcmap.c [1.12], gxfcmap.h [1.7]: 2000/11/29 05:50:03 lpd) The old code did not comply ISO/IEC C language standard and compiled wrongly to Mac, causing halftone problem on Mac. (gshtscr.c [1.5]: 2000/11/29 14:41:34 igorm) Adds macros for suffix subclass structures with 7 or 8 additional pointers (1-6 and 9 existed already). (gsstruct.h [1.7]: 2000/12/04 01:11:53 lpd) Extensively revises and updates the pdfwrite text handling code to support processing and embedding of all types of fonts (except for Type 3 and CIDFontType 1, which are defined by PostScript procedures), and all variants of 'show' (including kshow and glyphshow). In particular, Type 0 fonts with all FMapTypes (including CMap-based), CIDFontType 0 and 2 fonts, and both standard and non-standard CMaps are supported. (gdevpsf.h [1.9], gdevpsf2.c [1.11], gdevpsfm.c [1.4], gdevpsft.c [1.6], gdevpsfu.c [1.6]: 2000/12/08 23:35:38 lpd) Moves definitions of gs_state_do_ptrs and gs_state_num_ptrs from gsstate.c to gzstate.h since they depend on the contents of struct gs_state_s defined there. (gsstate.c [1.9], gzstate.h [1.4]: 2000/12/11 12:52:16 alexcher) Splits off the code for downsampling an oversampled character bitmap into a separate file. (gsbitcom.c [1.1], gsbitops.c [1.3]: 2000/12/14 00:14:52 lpd) branches: 1.1.2; Fix: Seek was broken and PDF interpreter failed when FILE_IMPLEMENTATION=fd The implementation of streams using direct OS calls is extended to support MSVC && Win32. close_.h is replaced by more general unistd_.h (unistd_.h [1.1]: 2000/12/19 03:35:40 alexcher) Brings gxfill.c up to date with current coding standards (except for adding _t to the names of locally defined structure types); also puts #ifdef FILL_TRAPEZOIDS around a little more code that tests 'if (fill_trapezoids)'. (gxfill.c [1.6]: 2000/12/21 16:10:36 lpd) Updates repository for 6.60 release. (gscdef.c [1.11]: 2001/01/01 00:24:06 lpd)Other

The following projects are in a partially completed state:
Incompatible changes
(Procedures) - The -Zv and -ZV switches now trace alpha/transparency features. - The program name is now AFPL Ghostscript rather than Aladdin Ghostscript. - The default Windows installation directory is now c:\gs rather than c:\Aladdin. (Utilities) - lib/pdfeof.ps is deleted; its functionality is included in the standard code. (Drivers) - The X driver now implements sync_output using XSync(False) rather than XFlush(). (Library) - gdev_vector_dopath now never returns 1. - Color space types now have a new, required, "equal" procedure.Documentation

(doc/News.htm [1.60]: 2000/08/24 05:42:30 lpd) Brings the (still mostly stubbed) transparency code to a more self-consistent state. (doc/Language.htm [1.13]: 2000/08/30 01:34:40 lpd) Completes the parsing of .{begin,end}transparency{group,mask}, except for the TransferFunction for masks. The specification is still subject to change. (doc/Language.htm [1.14]: 2000/08/30 15:03:36 lpd) Divides the list of documents according to whether the document is for users, for developers, or both.

Fixes problems: - The PostScript image writing drivers (psmono/gray/rgb) didn't set the page size in the output, and didn't produce DSC-compliant output. (devs.mak [1.31]: 2000/08/09 06:55:45 lpd) - The FlateEncode and zlibEncode filters didn't implement the "Effort" parameter. (fix from Alex Cherepanov) (int.mak [1.28]: 2000/08/09 16:55:24 lpd) - Because "-" as an OutputFile now references the %stdout IODevice, it no longer worked in configurations without a PostScript interpreter. Fixing this required factoring out the stdin/out/err IODevices and providing an implementation that didn't reference the PostScript interpreter. (int.mak [1.32], lib.mak [1.34], ugcclib.mak [1.3]: 2000/09/07 06:14:45 lpd) - Configurations including PDF but not PostScript didn't include all the PostScript LL3 features needed to interpret PDF 1.3 et seq.

(gsfcmap.c [1.7]: 2000/09/21 02:44:44 lpd) - CID-keyed (FMapType 9) composite fonts didn't return the correct parsed character code, possibly causing widthshow or cshow to produce incorrect output. (gsfcmap.c [1.8], gsfcmap.h [1.4]: 2000/09/21 03:02:03 lpd) - Works around ANSI C's unreasonable new aliasing restrictions. (gsnogc.c [1.5]: 2000/09/22 04:17:52 lpd) - The 'head' table in embedded TrueType fonts had a length of 56; it should have a length of 54 and be followed by 2 padding bytes. (gdevpsft.c [1.4]: 2000/09/26 06:42:05 lpd) Initializes files for the 6.24 fileset. (gscdef.c [1.7]: 2000/08/09 16:54:02 lpd) Adds the PDF "overprint mode" to the graphics state.

All API and operator additions are now implemented (at least as stubs) and documented, as is bookkeeping for the new scalar graphics state members (but not for the soft masks or the transparency group stack).

On some files, the speedup is dramatic. (gsalloc.c [1.6]: 2000/08/26 01:18:33 lpd) Completes an edit that accidentally left the repository in an inconsistent state. (gxclpath.c [1.6], gxclrast.c [1.6]: 2000/08/26 03:19:56 lpd) Implements some minor improvements to the freelist algorithms that can produce nearly a factor of 2 speedup in some allocation-intensive situations. (gsalloc.c [1.7], gxalloc.h [1.4]: 2000/08/26 03:21:34 lpd) Brings the (still mostly stubbed) transparency code to a more self-consistent state.

(gximag3x.c [1.2]: 2000/08/30 04:29:56 lpd) Completes the parsing of .{begin,end}transparency{group,mask}, except for the TransferFunction for masks. The specification is still subject to change. (gstparam.h [1.4], gstrans.c [1.4], gstrans.h [1.4]: 2000/08/30 15:03:36 lpd) Adds documentation on proposed driver interface additions for managing the transparency rendering stack.

(gscspace.h [1.4]: 2000/09/10 05:21:44 lpd) Changes the -Zv switch to trace alpha/transparency-related features. (gdevabuf.c [1.2]: 2000/09/10 05:23:10 lpd) Implements another chunk of the PDF 1.4 transparency features, fixing some bugs in the previous code. (gstparam.h [1.5], gstrans.c [1.6], gximag3x.c [1.3]: 2000/09/10 05:26:27 lpd) Moves the Matte entry of soft mask images from the main structure to the mask structures, and changes Matted to has_Matte. (gsipar3x.h [1.2], gximag3x.c [1.5], gximag3x.h [1.2]: 2000/09/11 04:08:13 lpd) Adds a default implementation of soft-masked images that simply ignores the mask. (gximag3x.c [1.6]: 2000/09/11 04:38:01 lpd) Upgrades the proposed driver interface transparency extension from comments to macros, changing the name 'discard_transparency_level' to 'discard_transparency_layer'. (gstrans.c [1.8], gstrans.h [1.5]: 2000/09/11 20:13:31 lpd) Finishes the (dummy) implementation of the transparency layer stack in the graphics library.

Incompatible changes
(Drivers) - With high-level drivers ([e]pswrite, pdfwrite, pxl*, cgm*), changing the OutputFile after writing one or more pages now causes an error. (Interpreter) - By default, copydevice will only copy a device prototype. - Some internal references to contexts in zcontext.c are changed from direct pointers to context indices. - Renames internal types to add a _t: ctx_list, ctx_status, gs_context, gs_condition, gs_lock. (Library) - By default, gs_copydevice[2] will only copy a device prototype.Documentation
Fixes problems: - Local GC in a multi-context system caused a crash. Also updates all the internal type names in zcontext.c by adding a _t suffix if necessary. (doc/News.htm [1.54]: 2000/07/10 23:56:55 lpd) - With some high-level drivers, changing the OutputFile after opening the device could cause a crash. After the fix, doing this works properly if no pages have actually been written out, but causes a rangecheck error if any pages have been written. (This is required to maintain internal consistency.) (doc/News.htm [1.55]: 2000/07/12 14:02:03 lpd) - The documented limit on the length of a file name was incorrect.

(doc/News.htm [1.52]: 2000/07/06 02:45:06 lpd) Adds a finish_copydevice device procedure, for cleaning up after copying the bits of a device prototype or instance. For safety, the default implementation only allows copying the prototype, not instances. This is a NON-BACKWARD-COMPATIBLE change; however, using copydevice on a device instance never worked reliably, so it should not have been used this way before.

Fixes problems: - $(GLGEN)/md5.h wasn't deleted after compilation. (lib.mak [1.26]: 2000/07/09 23:19:59 lpd) - TrueType font loading now requires the Adobe glyph list, but this dependency was missing from the makefile. (int.mak [1.26]: 2000/07/19 08:11:15 lpd) - During compilation, GLSRCDIR was searched before GLGENDIR. (We're very surprised that this didn't cause detectable trouble before.) (lib.mak [1.27]: 2000/07/19 14:32:00 lpd) - The dependency on gsparamx.$(OBJ) was incorrectly attached to pdfwrite.dev rather than psdf.dev. (devs.mak [1.30]: 2000/08/03 17:42:52 lpd) - 'pre' didn't work with dates in August or September (Tcl doesn't accept 08 and 09 as valid numbers).

Version 6.22 (2000-07-05)
This fileset consists mostly of bug fixes. It also further improves the PDF writer, which now handles ImageType 3 images and PatternType 2 (shading) patterns.
All problems registered on SourceForge numbered 108819 or lower are closed, except for the following: 101549, 101814, 101905, 101955, 102146, 102735, 104118, 105289, 105558, 106340, 106652, 108639.
The following projects are in a partially completed state in the PDF writer:
Incompatible changes
(Procedures) - Versions now have odd numbers during development, even numbers when released. - The TMPDIR environment variable, if set, now takes precedence over TEMP. - On MS-DOS, MS Windows, and OS/2 platforms, the batch files that invoke Ghostscript now use a default name of gswin32 or gswin32c rather than simply gs. (Drivers) - The PCL drivers now select a given paper size if the requested height is at least 0.1" greater than the height of the next smaller paper size, rather than if the requested height is at least as large as that of the given paper size. (Interpreter) - user_names_p and system_names_p may now be NULL: clients must check this. - scan_comment_proc and scan_dsc_proc are now deprecated, and will disappear in the near future. - The values in psuserparams are now checking procedures rather than parameter values. - Comments beginning with %! are treated as "DSC comments", like comments beginning with %%. (Library) - The macro for declaring the fill_rectangle procedure of a shading is now upper-case. The fill_rectangle procedure is now a member of a procs structure; there is a new macro for calling it. - The parameter list and return value for gs_currentgray have changed. This is very unfortunate, but it was unavoidable.Documentation
Fixes problems: - The batch files for MS-DOS, MS Windows, and OS/2 referred to the executable by the name 'gs'. They now use environment variables GS (graphical) and GSC (console) for the executable names, defaulting to gswin32 and gswin32c respectively. (doc/News.htm [1.45], doc/Use.htm [1.6]: 2000/05/20 20:53:04 lpd) - The -dCompatibilityLevel= switch was incorrectly identified in one place as -dCompatibility=. (doc/Ps2pdf.htm [1.11]: 2000/05/22 21:29:45 lpd) - [gs_]currentgray didn't return the correct value if the current color space was a DeviceN space using the alternate space. (doc/News.htm [1.49]: 2000/07/03 15:28:26 lpd) - Fixes a couple of typos. (doc/Release.htm [1.12]: 2000/07/04 19:19:38 lpd) - The "smoke test" procedure for fileset releases didn't stress the banding code nearly as hard as intended. (doc/Release.htm [1.13]: 2000/07/05 04:50:13 lpd) Adds predefined pdfwrite settings similar to the three standard settings in Adobe Acrobat Distiller 4, plus a "default" setting, with -dPDFSETTINGS=/settingname. (doc/Ps2pdf.htm [1.10]: 2000/04/29 02:29:20 lpd) Increments the version number to 6.23. From now on, we use odd numbers during development, even numbers for released filesets.

(doc/Ps2pdf.htm [1.13]: 2000/06/21 18:06:07 lpd) Adds user parameters ProcessComment and ProcessDSCComment. If not null, these procedures are called with the file and the comment line whenever the scanner detects a comment (or non-DSC comment) or DSC comment. NOTE: the interpreter is currently patched so that ProcessComment is never called. (doc/Language.htm [1.4], doc/News.htm [1.48]: 2000/06/27 00:53:38 lpd) Adds a reference to a user-maintained Czech translation of the Ghostscript 'man' pages.

Version 6.21 (2000-04-28)
This fileset includes more PDF writer enhancements: conversion of embedded Type 1 fonts to Type 1C (smaller), handling of more color spaces for images, ImageType 4 images, compression of mask images, support for (tiled) Pattern colors, more graphics state distiller parameters, recording of graphics state functions in the output. It also greatly improves the space usage and loading time for CMaps.
All problems registered on SourceForge numbered 104890 or lower are closed, except for the following: 101549, 101814, 101905, 101955, 102146, 102735, 103528, 104118, 104375.
The following projects are in a partially completed state in the PDF writer:
Incompatible changes
(Drivers) - The downsampling filters now require WidthIn and HeightIn, replacing Columns. - The gp_ procedures for managing screen swapping between console and graphics are removed. - Any driver that processes the pdfmark pseudo-parameter must now also return null for the "value" of the pdfmark parameter when (and only when) specifically requested. (PDF writer) - The last argument of pdf_alloc_font has changed. - pdf_set_color is renamed pdf_set_pure_color. - When producing PDF 1.3 output, the base 14 fonts are now candidates for embedding just like any other fonts. (Interpreter) - The .fontproperties procedure in gs_fonts.ps now takes an additional argument. - The interpreter must no longer reference stdin/out/err directly. (Library) - The internal representation of CMaps is changed completely, and has several new required members. - gs_cmap is renamed gs_cmap_t; gx_code_map is renamed gx_code_map_t. - Clients creating CMaps must call gs_cmap_init to initialize them. - The library must no longer reference stdin/out/err directly.Documentation

(toolbin/makeset.tcl [1.3]: 2000/04/07 19:39:27 lpd) - A dependency wasn't updated when moving the gdevpsf* rules from devs.mak to lib.mak. (lib.mak [1.10]: 2000/04/07 19:40:25 lpd) - The dependencies in the makefile weren't updated for the pdfwrite font embedding overhaul. (devs.mak [1.11]: 2000/04/10 18:57:33 lpd) - Once again, the dependencies hadn't been updated.

(unixinst.mak [1.9]: 2000/04/14 04:06:13 lpd) - The Color LaserJet 5 drivers were incorrectly identified as "supported" rather than "contributed". (contrib.mak [1.7], devs.mak [1.17]: 2000/04/20 17:12:54 lpd) - PDF images with a bitmap Mask caused errors or produced incorrect output. (int.mak [1.20]: 2000/04/24 00:59:04 lpd) Completely redesigns the representation of CMaps, to reduce space requirements and make comparing them more reasonable, changing gs_cmap to gs_cmap_t and gx_code_map to gx_code_map_t.

(devs.mak [1.13]: 2000/04/11 18:31:32 lpd) Splits off creation and writing of color spaces, and writing color values, into a separate file. Adds support for (Function-based) Separation and DeviceN color spaces, general Pattern color spaces, and procedure-based Indexed color spaces. Adds some code to support Pattern colors, but stubs it out because it depends on changes in the image writing code that haven't been integrated yet. In fact, most of the new code isn't called yet, either.

(examples/annots.pdf [1.1]: 2000/04/28 10:51:02 lpd)Streams
Fixes problems: - FILE_IMPLEMENTATION=both was broken (by the introduction of sread_subfile). (sfxfd.c [1.3]: 2000/04/10 02:41:48 lpd) - flushfile and closefile didn't properly flush streams whose final target was a procedure, and closefile didn't actually close them. (This is a very old bug.) (stream.c [1.6]: 2000/04/18 05:50:15 lpd) - The PixelDifference filters (Predictor = 2) weren't implemented for Colors > 4 and BitsPerComponent != 8, and they dropped trailing bytes if the length of the data wasn't an exact multiple of the pixel size. (spdiff.c [1.2]: 2000/04/22 03:55:22 lpd) Enhances the ASCII85Encode filter to avoid %! at the beginning of a line of output, in addition to avoiding %% which it did already.

(seexec.c [1.2], sfilter.h [1.5]: 2000/04/22 16:03:18 lpd) Adds a MD5Encode filter, which computes the 16-byte MD5 digest of the input. No output is produced until the filter is closed. (smd5.c [1.1], smd5.h [1.1]: 2000/04/27 14:39:57 lpd)Library
Fixes problems: - Fixes some signed/unsigned char * mismatches. (gdevpsf2.c [1.5]: 2000/04/07 15:27:14 lpd) - Writing a Type 2 CFF with multiply-encoded glyphs produced an incorrect Encoding. Also, when producing output for PDF 1.2 files, no longer emits certain opcodes that cause an (unjustified) error in Acrobat Reader 3 for Linux. (gdevpsf.h [1.3], gdevpsf2.c [1.6]: 2000/04/10 07:42:31 lpd) - gsmisc.c didn't compile in DEBUG mode on systems with a non-standard prototype for the sqrt function. (gsmisc.c [1.3]: 2000/04/10 16:00:31 lpd) - One picky compiler complained about (1L << 31). (gsmisc.c [1.4]: 2000/04/10 17:21:41 lpd) - putdeviceparams allowed a PageSize or .MediaSize value with the wrong number of elements to take effect. (gsdparam.c [1.2]: 2000/04/19 05:59:05 lpd) - The elimination of stdin/out/err also eliminated some #defines that are needed for error printout. (gsio.h [1.3]: 2000/04/21 06:39:17 lpd) - The structure descriptor for ImageType 3 images was public rather than private. (gsiparm3.h [1.3], gximage3.c [1.2]: 2000/04/22 07:02:18 lpd) - The "point matching" feature of TrueType composite glyphs wasn't implemented, causing some composite (accented) characters to have their accents misplaced.

Version 6.20 (2000-04-06)
This fileset includes the first steps towards bringing the pdfwrite driver closer to matching Acrobat Distiller 4. Highlights:
All problems registered on SourceForge numbered 103963 or lower are closed, except for the following: 101549, 101814, 101829, 101905, 101955, 102046, 102047, 102132, 102146, 102735, 102901, 103016, 103528, 103963.
Incompatible changes
(Procedures) - The default value of FPU_TYPE in all Windows and OS/2 makefiles is now 387 rather than 0. - The process for reporting problems has changed significantly. (PDF writer) - The Cos procedures no longer take the device as an argument, except for object-creating procedures, which now take the device rather than an allocator. - The is_object member of Cos values is replaced by value_type. Clients must use COS_VALUE_IS_OBJECT() to test whether a value is an object reference. - The Cos procedures that take C strings no longer copy the string. - The argument of cos_write_object is no longer const. (Drivers) - The default BufferSpace for printer drivers is now 4 Mb. - Device halftone order implementations must now provide a new bit_index procedure. - The image argument for psdf_setup_image_filters is changed from gs_image_t to gs_pixel_image_t. - The font-related psdf_ procedures are renamed psf_. (Streams) - The interface to the [T]BCP filters is now in a separate file, sbcp.h. (PDF interpreter) - The internal beginpage procedure is renamed dictbeginpage, and now takes a dictionary argument. (Interpreter) - The argument list for the internal build_gs_TrueType_font procedure has changed. - The zcharstring_glyph_outline procedure is renamed zchar1_glyph_outline. - The Instances dictionary of resources is renamed .Instances. (Library) - ImageType 4 images now give an error if a MaskColor value is out of the range of possible sample values. - The definition of gs_param_key_t, the key type returned by parameter list enumeration, is changed. - Implementors of parameter lists must now call gs_param_list_init to initialize the common members. - st_indexed_map is now private. Clients allocating instances of this structure must now call alloc_indexed_map. - Setting a transfer map as the identity mapping now requires calling gx_set_identity_transfer. - gs_cid_system_info is renamed gs_cid_system_info_t. - The get_outline procedure of a Type 42 or Type 11 (CIDFontType 0) font now returns 1 if the string was newly allocated and can be freed by the client. - The procs member of gs_type1_data is now an in-line structure rather than a pointer to a const structure.Documentation
Fixes problems: - If log2_transfer_map_size > 8, identity transfer functions returned garbage. The fix requires that if a client wants to set a transfer function to the identity mapping, it must call gx_set_identity_transfer rather than simply setting the procedure to gs_identity_transfer. (doc/News.htm [1.13]: 2000/03/19 17:14:47 lpd) - In PDF files, the page CropBox was not being used to clip the output. (doc/News.htm [1.18]: 2000/03/21 23:08:32 lpd) - Fixes several problems in resourceforall and resource loading: the operands of resourceforall were restored even in the case of an error in the client's procedure; the name Instances had special meaning for some Adobe code; resourceforall caused an invalidaccess error if an operand was in local VM but the current VM was global; loading a resource from a file could cause a typecheck error if the file left values on the operand stack. (doc/News.htm [1.25]: 2000/04/04 22:26:02 lpd) - The location of the lists of supported and unsupported drivers was incorrect. (doc/Bug-info.htm [1.2]: 2000/04/07 03:01:52 lpd) Undoes an accidental RCS ID substitution in what was supposed to be literal text. (doc/Htmstyle.htm [1.2]: 2000/03/18 22:29:03 lpd) Increments the version number to 6.20, in anticipation of the next release. (We do this at the beginning of the development for a release, not the end.) (doc/History6.htm [1.4], doc/News.htm [1.6]: 2000/03/19 00:27:22 lpd) Splits out the [T]BCP filter interface into a separate file. (doc/News.htm [1.7]: 2000/03/19 02:40:18 lpd) Documents the fact that ImageType 4 images now cause an error for out-of-range MaskColor values. (doc/News.htm [1.8]: 2000/03/19 04:32:09 lpd) Updates the change log with recent changes. (doc/Changes.htm [1.4]: 2000/03/19 05:39:58 lpd) Adds a new document listing projects with which we are seeking help. Also makes the description of Changes.htm and News.htm more accurate. (doc/New-user.htm [1.2], doc/Projects.htm [1.1], doc/Readme.htm [1.3]: 2000/03/19 06:07:15 lpd) Changes the default value of BufferSpace to 4 Mb. In desktop applications, this is a reasonable value that can substantially improve performance (especially for color printers); embedded applications will want to set BufferSpace themselves in any case. (doc/News.htm [1.9]: 2000/03/19 06:51:13 lpd) Changes the key type returned by parameter list enumeration to include a persistence flag, makes C parameter lists support non-persistent keys, and upgrades GC descriptors so that parameter lists can be used non-transiently; updates implementors of parameter lists to call gs_param_list_init to initialize the common members, which is now required. (doc/News.htm [1.10]: 2000/03/19 15:16:11 lpd) Documents the fact that drivers that device halftone order implementations must now provide the new bit_index procedure. (This should have been documented when bit_index was introduced!) (doc/News.htm [1.11]: 2000/03/19 15:47:47 lpd) Makes st_indexed_map private. Clients must now use the constructor procedure alloc_indexed_map rather than allocating instances directly. (doc/News.htm [1.12]: 2000/03/19 16:37:28 lpd) Update the date and change log for the latest batches of checked-in changes. (doc/Changes.htm [1.5]: 2000/03/19 17:29:57 lpd) Adds a PDF linearizer ("optimizer"). This is a separate utility (not integrated with the pdfwrite driver), written in PostScript. (doc/Psfiles.htm [1.2]: 2000/03/20 04:31:22 lpd) Adds parsing for the remaining Acrobat Distiller 4 parameters. Implements the LockDistillerParams, xxxDownsampleThreshold, xxxImageDict, and xxxACSImageDict distiller parameters. Implements DCTEncode as an xxxImageFilter option (it used to cause a crash). Makes the AutoFilterxxxImages distiller parameters select JPEG encoding (with ACSDict) if the image has 8 bits per component and is not Indexed, and LZW/Flate otherwise: this still isn't right, but it's closer. Implementation changes: Changes the implementation of distiller parameter dictionaries from stream states to parameter lists; changes the test for masks in psdf_setup_image_filters, and changes the image argument from gs_image_t to gs_pixel_image_t. (doc/News.htm [1.14]: 2000/03/20 05:40:04 lpd) Moves font-writing support into a new module (gdevpsf*), changing the source file names. Adds the ability to write CFF fonts, with either Type 1 or Type 2 CharStrings; unfortunately, Acrobat Reader appears not to accept CFF fonts with Type 1 CharStrings. Adds the ability to convert Type 1 CharStrings to Type 2, including optimizing sequences of Type 1 operators into a single Type 2 operator. Implements writing CIDFontType 0 CFF fonts (CIDFonts) [NOT TESTED]. Starts (just barely) to remove more unneeded information from embedded TrueType fonts. (doc/News.htm [1.15]: 2000/03/20 07:02:12 lpd) Updates the consolidated change log with today's changes. (doc/Changes.htm [1.6]: 2000/03/20 07:18:38 lpd) Starts to move support for CIDFontType 0 and 2 into C code, needed by the PDF writer for handling CID-keyed fonts. Implements GlyphDirectory for CIDFonts. Makes GDBytes and CIDMapOffset optional for CIDFontType 0 fonts that have a GlyphDirectory (not documented in the PLRM, but clearly correct). Implements Adobe 3011 features: integer and dictionary CIDMaps, and the MetricsCount entry, in CIDFontType 2 fonts (but only in the C code, which isn't hooked in yet, not in the PostScript code in gs_cidfn.ps.) (doc/News.htm [1.16]: 2000/03/20 19:53:06 lpd) Notes that the argument list for the internal build_gs_TrueType_font procedure has changed, as part of the CIDFont migration to C code. (doc/News.htm [1.17]: 2000/03/20 20:04:20 lpd) Adds invocation scripts and documentation for the PDF "optimizer". (man/pdfopt.1 [1.1]: 2000/03/21 17:01:33 lpd) Updates information about reporting problems when using Ghostview or GSview. (doc/Bug-form.htm [1.3], doc/New-user.htm [1.3]: 2000/03/22 22:13:49 lpd) Checks in the latest consolidated change log. (doc/Changes.htm [1.7]: 2000/03/24 05:04:55 lpd) Substantially enhances the Cos object machinery. Interface: Adds a few more procedures, including a procedure to create a stream that writes directly into a Cos stream object, procedures for putting more kinds of values into arrays and dictionaries, and a param_list interface. Changes Cos objects to store a reference to the PDF device, and removes the device argument from all Cos procedures other than object creation. Replaces the Boolean is_object member of Cos values by a value_type enum: clients must now use COS_VALUE_IS_OBJECT() to test whether a value is an object reference. To reduce allocator overhead, makes the Cos procedures that take C strings no longer copy the string. Records whether each Cos object has been written into the output, so that in the future (but not in this batch of changes) resource definitions can be copied at the end of each page. Implementation: Moves more of the implementation of Cos objects to the .c file. (doc/News.htm [1.19]: 2000/03/24 06:12:52 lpd) Adds parsing for the remaining Acrobat Distiller 4 parameters, although most of them don't have any effect yet; brings documentation up to date. (doc/Ps2pdf.htm [1.3]: 2000/03/28 07:36:58 lpd) Implements LockDistillerParams; completes the StartPage/EndPage fix checked in just before. (doc/Ps2pdf.htm [1.4]: 2000/03/28 07:52:06 lpd) Changes the default value of FPU_TYPE in all Windows and OS/2 makefiles from 0 to 387, since all current desktop CPUs include floating point hardware. (doc/News.htm [1.20]: 2000/03/28 17:03:48 lpd) Changes the get_outline / glyph_data procedure for getting encoded font outline data to return an indication of whether the outline data were just allocated and can be freed by the client. (This is a possibly non-backward-compatible change.) (doc/News.htm [1.21]: 2000/03/28 18:47:02 lpd) Adds a note about bogus "ANSI aliasing" warnings from the DEC C compiler. (doc/Make.htm [1.8]: 2000/03/29 19:29:08 lpd) Changes the procs structure of gs_type1_data to an in-line structure rather than a pointer to a const structure. (Needed for moving CIDFontType 0 support into C.) (doc/News.htm [1.22]: 2000/03/29 22:10:31 lpd) Updates the change log with recent changes. (doc/Changes.htm [1.8]: 2000/03/30 07:59:39 lpd) Creates a real list of projects on which help would be appreciated. (doc/Projects.htm [1.2]: 2000/04/01 00:43:11 lpd) Finishes implementing the ability to write CIDFontType 0 CFFs. This involved a surprising number of changes in other font-related files. (doc/News.htm [1.23]: 2000/04/02 07:38:46 lpd) Updates the documentation on preparing releases to reflect the addition of the toolbin directory. (doc/Release.htm [1.7]: 2000/04/02 18:56:58 lpd) Implements the AutoRotatePages distiller parameter. (doc/Ps2pdf.htm [1.5]: 2000/04/03 02:54:41 lpd) Updates the problem reporting procedure to use SourceForge; separates the description of the procedure from the reporting form. (doc/Bug-form.htm [1.4], doc/Bug-info.htm [1.1], doc/New-user.htm [1.4], doc/News.htm [1.24], doc/Readme.htm [1.4]: 2000/04/04 04:14:02 lpd) Updates release dates and version numbers.

(doc/Release.htm [1.8]: 2000/04/07 05:24:29 lpd)Procedures
Fixes problems: - pdfread.dev incorrectly depended on dpsnext_. (int.mak [1.4]: 2000/03/19 02:00:09 lpd) - The referenced libpng version hadn't been updated to 1.0.5. (openvms.mmk [1.3]: 2000/03/20 16:38:46 lpd) - The MSVC++ 6 compiler no longer recognizes the /FPi87 switch. (msvccmd.mak [1.2]: 2000/03/31 05:06:53 lpd) - MSVC versions before 5, not before 6, recognize /FPi87. (msvccmd.mak [1.3]: 2000/03/31 05:50:33 lpd) - Removes some occurrences of $,I,d,: that shouldn't be substituted. (toolbin/pre [1.2]: 2000/04/07 05:20:35 lpd) Increments the version number to 6.20, in anticipation of the next release. (We do this at the beginning of the development for a release, not the end.)

(int.mak [1.5], lib.mak [1.3]: 2000/03/19 05:37:38 lpd) Adds dependencies for the new implementation of FunctionType 4 functions. (int.mak [1.6]: 2000/03/19 07:03:53 lpd) Splits off "vanilla" Functions into separate files, in anticipation of removing them (they were only used to implement PostScript Calculator Functions). (lib.mak [1.4]: 2000/03/19 07:33:08 lpd) Update the date and change log for the latest batches of checked-in changes. (version.mak [1.7]: 2000/03/19 17:29:57 lpd) Moves font-writing support into a new module (gdevpsf*), changing the source file names. Adds the ability to write CFF fonts, with either Type 1 or Type 2 CharStrings; unfortunately, Acrobat Reader appears not to accept CFF fonts with Type 1 CharStrings. Adds the ability to convert Type 1 CharStrings to Type 2, including optimizing sequences of Type 1 operators into a single Type 2 operator. Implements writing CIDFontType 0 CFF fonts (CIDFonts) [NOT TESTED]. Starts (just barely) to remove more unneeded information from embedded TrueType fonts.

(devs.mak [1.5], int.mak [1.7], lib.mak [1.6]: 2000/03/20 07:16:35 lpd) Updates the makefile for the renaming of gdevpsdf.c => gdevpsdu.c. (devs.mak [1.6]: 2000/03/20 19:30:35 lpd) Starts to move support for CIDFontType 0 and 2 into C code, needed by the PDF writer for handling CID-keyed fonts. Implements GlyphDirectory for CIDFonts. Makes GDBytes and CIDMapOffset optional for CIDFontType 0 fonts that have a GlyphDirectory (not documented in the PLRM, but clearly correct). Implements Adobe 3011 features: integer and dictionary CIDMaps, and the MetricsCount entry, in CIDFontType 2 fonts (but only in the C code, which isn't hooked in yet, not in the PostScript code in gs_cidfn.ps.) (int.mak [1.8], lib.mak [1.7]: 2000/03/20 19:53:06 lpd) Extends the C support for CIDFontType 0 fonts to include those with FontType 2 subfonts in the FDArray (an Adobe 3011 addition, specifically for CFF fonts). (int.mak [1.9]: 2000/03/21 07:43:42 lpd) Adds invocation scripts and documentation for the PDF "optimizer". (unixinst.mak [1.6]: 2000/03/21 17:01:33 lpd) Splits off the ReusableStreamDecode filter as a separate module, since CIDFontType 0 fonts will use it even in LanguageLevels below 3. (int.mak [1.10]: 2000/03/21 21:34:57 lpd) Makes file streams remember the file name, needed for efficiently implementing reusable streams. (int.mak [1.11]: 2000/03/23 02:13:40 lpd) Checks in the latest consolidated change log. (version.mak [1.8]: 2000/03/24 05:04:55 lpd) Changes the implementation of incrementally loaded CIDFontType 0 fonts to use a ReusableStreamDecode filter, in anticipation of moving the BuildGlyph procedure for these fonts from PostScript to C. (int.mak [1.12], version.mak [1.9]: 2000/03/27 16:36:24 lpd) Changes the default value of FPU_TYPE in all Windows and OS/2 makefiles from 0 to 387, since all current desktop CPUs include floating point hardware.

(version.mak [1.10]: 2000/03/30 07:59:39 lpd) Cleans up some dependencies missed at the last checkin. (devs.mak [1.7], int.mak [1.13]: 2000/03/31 05:03:30 lpd) Finishes implementing the ability to write CIDFontType 0 CFFs. This involved a surprising number of changes in other font-related files. (int.mak [1.14]: 2000/04/02 07:38:46 lpd) Adds a variety of tools used to build and distribute Ghostscript releases. The only documentation is comments in the files themselves, and there isn't much of it. All aspects of these tools are subject to change without notice. (toolbin/3way.tcl [1.1], toolbin/cvs2hist.py [1.1], toolbin/errlist.tcl [1.1], toolbin/gsmake.tcl [1.1], toolbin/headers.tcl [1.1], toolbin/leaks.tcl [1.1], toolbin/makeset.tcl [1.1], toolbin/package.tcl [1.1], toolbin/pre [1.1], toolbin/pre.chk [1.1], toolbin/precheck.tcl [1.1], toolbin/smoke.ps [1.1], toolbin/suite.tcl [1.1], toolbin/tmake.tcl [1.1]: 2000/04/02 18:44:27 lpd) Moves gsindent from src to toolbin. (toolbin/gsindent [1.1]: 2000/04/02 18:56:25 lpd) Adds an #include required by the Watcom compiler. (devs.mak [1.8]: 2000/04/05 19:51:54 lpd) Adds a missing dependency. (lib.mak [1.8]: 2000/04/07 03:00:56 lpd) Updates a few dependencies for the release. (int.mak [1.15]: 2000/04/07 05:23:12 lpd) Updates the build date for the release. (version.mak [1.11]: 2000/04/07 05:25:18 lpd) Adds .cvsignore files, to prevent bogus warnings on cvs update. (.cvsignore [1.1], src/.cvsignore [1.1]: 2000/04/05 19:46:04 lpd)Utilities
Fixes problems: - A couple of places in the Windows code didn't correctly handle Ghostscript version 6.64, 7 April 2001 21:45:03 lpd) - Replaces a final exit() with a return, to avoid a compiler warning. (genconf.c [1.2]: 2000/04/05 19:53:27 lpd) Makes geninit remove whitespace adjacent to hex and base-85 string literals. (geninit.c [1.2]: 2000/03/18 22:51:24 lpd) Adds a PDF linearizer ("optimizer"). This is a separate utility (not integrated with the pdfwrite driver), written in PostScript. (lib/pdfopt.ps [1.1], lib/pdfwrite.ps [1.1]: 2000/03/20 04:31:22 lpd) Replaces the O(N^2) sorting algorithm for printing unencoded characters with a O(N log N) algorithm, which makes printing Unicode and Chinese/Japanese fonts practical. (lib/prfont.ps [1.2]: 2000/03/21 06:39:49 lpd) Adds invocation scripts and documentation for the PDF "optimizer". (lib/pdfopt [1.1], lib/pdfopt.bat [1.1], lib/pdfopt.ps [1.2]: 2000/03/21 17:01:33 lpd) Splits off the ReusableStreamDecode filter as a separate module, since CIDFontType 0 fonts will use it even in LanguageLevels below 3. (zfreuse.c [1.2]: 2000/03/21 21:34:57 lpd) Adds a variety of tools used to build and distribute Ghostscript releases. The only documentation is comments in the files themselves, and there isn't much of it. All aspects of these tools are subject to change without notice. (gsindent [1.2]: 2000/04/02 18:44:27 lpd)Drivers
Fixes problems: - The color_info member of the Windows and OS/2 printer devices (and other devices using PC-style palettes) wasn't initialized properly, causing improper behavior. (gdevos2p.c [1.2], gdevpccm.h [1.2], gdevwpr2.c [1.3]: 2000/03/20 21:05:11 lpd) - Fixes a bug in the mswinpr2 driver in the handling of BitsPerPixel. (gdevwpr2.c [1.4]: 2000/03/22 17:08:33 lpd) - In PCL XL output (pxl* drivers), if a PostScript image didn't provide enough source data, the remainder of the output image was erroneously filled with pixel value 0 (typically black or the foreground color). (gdevpx.c [1.2]: 2000/03/22 20:55:21 lpd) - In the output of the pswrite driver (pdf2ps, ps2ps), the showpage for each page occurred before, not after, the restore that ended the page contents. This contradicted Adobe's documentation, and made utilities like N-up printing not work properly. (gdevps.c [1.4]: 2000/03/28 00:52:46 lpd) - The PCL XL 2.0 value for sRGB color space was wrong, and the attribute for writing mode was missing. (gdevpxat.h [1.2], gdevpxen.h [1.2]: 2000/03/29 18:19:44 lpd) - When printing on monochrome LaserJet/DeskJet printers, the driver didn't set the number of copies to 1; on the LJ 4si, this sometimes caused double printing. (gdevdjet.c [1.2]: 2000/04/03 14:36:12 lpd) - Updates clients for the change in the last argument of cff_string_index from uint * to int *. (gdevpsf2.c [1.4]: 2000/04/05 19:55:29 lpd) Adds parsing for the remaining Acrobat Distiller 4 parameters. Implements the LockDistillerParams, xxxDownsampleThreshold, xxxImageDict, and xxxACSImageDict distiller parameters. Implements DCTEncode as an xxxImageFilter option (it used to cause a crash). Makes the AutoFilterxxxImages distiller parameters select JPEG encoding (with ACSDict) if the image has 8 bits per component and is not Indexed, and LZW/Flate otherwise: this still isn't right, but it's closer. Implementation changes: Changes the implementation of distiller parameter dictionaries from stream states to parameter lists; changes the test for masks in psdf_setup_image_filters, and changes the image argument from gs_image_t to gs_pixel_image_t. (gdevpsdf.h [1.4], gdevpsdi.c [1.3], gdevpsdp.c [1.3]: 2000/03/20 05:40:04 lpd) Moves font-writing support into a new module (gdevpsf*), changing the source file names. Adds the ability to write CFF fonts, with either Type 1 or Type 2 CharStrings; unfortunately, Acrobat Reader appears not to accept CFF fonts with Type 1 CharStrings. Adds the ability to convert Type 1 CharStrings to Type 2, including optimizing sequences of Type 1 operators into a single Type 2 operator. Implements writing CIDFontType 0 CFF fonts (CIDFonts) [NOT TESTED]. Starts (just barely) to remove more unneeded information from embedded TrueType fonts. (gdevpsd1.c [1.2], gdevpsdf.c [1.3], gdevpsdf.h [1.5], gdevpsdt.c [1.2], gdevpsf.h [1.1], gdevpsf1.c [1.1], gdevpsf2.c [1.1], gdevpsft.c [1.1], gdevpsfu.c [1.1], gdevpsfx.c [1.1]: 2000/03/20 07:02:12 lpd) Renames an inappropriately named file. (gdevpsdf.c [1.4], gdevpsdf.h [1.6], gdevpsdu.c [1.1]: 2000/03/20 19:03:43 lpd) Extends the C support for CIDFontType 0 fonts to include those with FontType 2 subfonts in the FDArray (an Adobe 3011 addition, specifically for CFF fonts). (gdevpsf.h [1.2]: 2000/03/21 07:43:42 lpd) Changes the procs structure of gs_type1_data to an in-line structure rather than a pointer to a const structure. (Needed for moving CIDFontType 0 support into C.) (gdevpsf1.c [1.2], gdevpsf2.c [1.2], gdevpsfx.c [1.2]: 2000/03/29 22:10:31 lpd) Finishes implementing the ability to write CIDFontType 0 CFFs. This involved a surprising number of changes in other font-related files. (gdevpsf2.c [1.3], gdevpsfu.c [1.2]: 2000/04/02 07:38:45 lpd) Slightly simplifies the output of the psmono and psgray drivers. (gdevpsim.c [1.2]: 2000/04/02 19:57:37 lpd) Adds an #include required by the Watcom compiler. (gdevpsf1.c [1.3]: 2000/04/05 19:51:54 lpd)PDF writer
Fixes problems: - The pointer enumeration procedure for pdf_image_enum was wrong, possibly producing a mangled pointer and a memory access error if a garbage collection occured while writing an image in a PDF file. (gdevpdfi.c [1.5]: 2000/03/20 05:54:13 lpd) - The computation for testing whether a tiled pattern could be represented in line, and whether it exceeded Acrobat Reader's size limit, was wrong, causing some patterns not to be represented as Patterns. (gdevpdfi.c [1.6]: 2000/03/20 05:58:15 lpd) - When ProcessColorModel=/DeviceCMYK, if the first object on a page or after changing the clipping path was white, the PDF writer would write it as black. (gdevpdfu.c [1.3]: 2000/03/21 18:36:36 lpd) - If a page ended with an incomplete outline tree, an invalid memory access occurred. (gdevpdf.c [1.3], gdevpdfm.c [1.2]: 2000/03/24 05:09:56 lpd) - The SP pdfmark didn't check that its argument was a graphics stream. (gdevpdfm.c [1.4]: 2000/03/24 06:18:39 lpd) - The name of the EndPage Distiller parameter collided with the EndPage page device parameter. (gdevpdfp.c [1.4]: 2000/03/28 07:45:25 lpd) - If two embedded fonts had the same base font, the PDF file could wind up with an invalid entry in the xref table. (gdevpdft.c [1.4]: 2000/04/01 01:18:32 lpd) Adds parsing for the remaining Acrobat Distiller 4 parameters. Implements the LockDistillerParams, xxxDownsampleThreshold, xxxImageDict, and xxxACSImageDict distiller parameters. Implements DCTEncode as an xxxImageFilter option (it used to cause a crash). Makes the AutoFilterxxxImages distiller parameters select JPEG encoding (with ACSDict) if the image has 8 bits per component and is not Indexed, and LZW/Flate otherwise: this still isn't right, but it's closer. Implementation changes: Changes the implementation of distiller parameter dictionaries from stream states to parameter lists; changes the test for masks in psdf_setup_image_filters, and changes the image argument from gs_image_t to gs_pixel_image_t. (gdevpdfi.c [1.4]: 2000/03/20 05:40:04 lpd) Moves font-writing support into a new module (gdevpsf*), changing the source file names. Adds the ability to write CFF fonts, with either Type 1 or Type 2 CharStrings; unfortunately, Acrobat Reader appears not to accept CFF fonts with Type 1 CharStrings. Adds the ability to convert Type 1 CharStrings to Type 2, including optimizing sequences of Type 1 operators into a single Type 2 operator. Implements writing CIDFontType 0 CFF fonts (CIDFonts) [NOT TESTED]. Starts (just barely) to remove more unneeded information from embedded TrueType fonts. (gdevpdff.c [1.2], gdevpdfw.c [1.2]: 2000/03/20 07:02:12 lpd) Substantially enhances the Cos object machinery. Interface: Adds a few more procedures, including a procedure to create a stream that writes directly into a Cos stream object, procedures for putting more kinds of values into arrays and dictionaries, and a param_list interface. Changes Cos objects to store a reference to the PDF device, and removes the device argument from all Cos procedures other than object creation. Replaces the Boolean is_object member of Cos values by a value_type enum: clients must now use COS_VALUE_IS_OBJECT() to test whether a value is an object reference. To reduce allocator overhead, makes the Cos procedures that take C strings no longer copy the string. Records whether each Cos object has been written into the output, so that in the future (but not in this batch of changes) resource definitions can be copied at the end of each page. Implementation: Moves more of the implementation of Cos objects to the .c file. (gdevpdf.c [1.4], gdevpdfi.c [1.7], gdevpdfm.c [1.3], gdevpdfo.c [1.2], gdevpdfo.h [1.2], gdevpdfr.c [1.2], gdevpdfu.c [1.4], gdevpdfx.h [1.3]: 2000/03/24 06:12:52 lpd) Changes a few initializations to suppress warnings from one picky compiler that doesn't like ptr = buf - 1 where buf is an array. (gdevpdfr.c [1.3]: 2000/03/28 02:01:34 lpd) Adds parsing for the remaining Acrobat Distiller 4 parameters, although most of them don't have any effect yet; brings documentation up to date. (gdevpdf.c [1.5], gdevpdfp.c [1.3], gdevpdfx.h [1.4]: 2000/03/28 07:36:58 lpd) Implements LockDistillerParams; completes the StartPage/EndPage fix checked in just before. (gdevpdf.c [1.6], gdevpdfp.c [1.5], gdevpdfx.h [1.5]: 2000/03/28 07:52:06 lpd) Changes the initial values of the "job control" parameters to match Acrobat Distiller 4. (gdevpdf.c [1.7], gdevpdfp.c [1.6], gdevpdfx.h [1.6]: 2000/03/28 07:57:14 lpd) Implements the AutoRotatePages distiller parameter. (gdevpdf.c [1.8], gdevpdft.c [1.5], gdevpdfu.c [1.5], gdevpdfx.h [1.7]: 2000/04/03 02:54:41 lpd)Interpreter (PDF)
Fixes problems: - Reading embedded compressed CIDFonts wasn't implemented. (lib/pdf_font.ps [1.3]: 2000/03/19 01:28:59 lpd) - PDF images with DeviceN color spaces caused an error. (lib/pdf_draw.ps [1.2]: 2000/03/19 01:44:53 lpd) - PDF images with a Mask ignored the mask. (lib/pdf_draw.ps [1.3]: 2000/03/19 01:46:27 lpd) - the PDF interpreter hadn't been updated for the move to library-based FunctionType 4 Functions, and still tried to bind the names true and false to the no longer existing operators .true and .false. (lib/pdf_draw.ps [1.5]: 2000/03/19 07:37:03 lpd) - FunctionType 2 and 3 functions didn't work. (lib/pdf_draw.ps [1.6]: 2000/03/19 15:23:10 lpd) - In PDF files, the page CropBox was not being used to clip the output. (lib/pdf_main.ps [1.4], lib/pdf_ops.ps [1.3]: 2000/03/21 23:08:32 lpd) - The "fix" for FunctionTypes 2 and 3 in PDF files had made things worse, because the code didn't distinguish between resolving to a PostScript function (for shadings) and resolving to a PostScript procedure (for halftones, BG/UCR, alternate color space mapping, etc.) (lib/pdf_draw.ps [1.7]: 2000/03/23 18:31:46 lpd) - Text with a Pattern color scaled the pattern according to the text matrix, not the default matrix of the marking context. (lib/pdf_base.ps [1.6], lib/pdf_main.ps [1.5], lib/pdf_ops.ps [1.4]: 2000/03/30 18:01:58 lpd) - Resolving a Shading didn't create a reusable stream for the shading data; since the data was then read at unpredictable times, the shading or other constructs in the PDF file could read incorrect data. (lib/pdf_draw.ps [1.8]: 2000/04/03 06:01:25 lpd) Adds a lforall procedure for the PDF linearizer. (lib/pdf_base.ps [1.3]: 2000/03/19 01:50:05 lpd) Changes the PDF interpreter so that following an object reference doesn't store the result back into the referring slot, and so that # # R always creates an indirect object. This is necessary for the PDF linearizer. It shouldn't have any visible effect (other than a possible small performance cost). (lib/pdf_base.ps [1.4], lib/pdf_draw.ps [1.4]: 2000/03/19 01:53:58 lpd) Refactors some code to make it usable by the PDF linearizer. (lib/pdf_main.ps [1.3]: 2000/03/19 17:26:42 lpd) Speeds up loading embedded Type 1 fonts a little. (lib/pdf_base.ps [1.5], lib/pdf_font.ps [1.4]: 2000/03/24 07:42:16 lpd) Speeds up reading embedded Type 1 fonts a little more. (lib/pdf_font.ps [1.5]: 2000/03/24 16:28:26 lpd)Interpreter
Fixes problems: - Font substitution was broken. (lib/gs_fonts.ps [1.3]: 2000/03/19 00:22:05 lpd) - The CFF reader gave an error if a font included any Subrs (it's very surprising that this hasn't surfaced before, but apparently Acrobat Distiller always produces CFF fonts with no Subrs); the CFF reader didn't default lenIV to -1 for Type 1 CharStrings; the CFF reader wasn't able to read CIDFonts. (lib/gs_cff.ps [1.3], lib/gs_cidfn.ps [1.4]: 2000/03/19 00:45:40 lpd) - EXTEND_NAMES had stopped working, because not all places that needed the index of a name ref used name_index rather than r_size (ilocate.c), and because the high_index value in the name sub-table was set incorrectly (iname.c). (ilocate.c [1.2], iname.c [1.2]: 2000/03/19 01:33:23 lpd) - The attribute check for Functions being executed was incorrect (always succeeded). (zfunc.c [1.2]: 2000/03/19 02:12:37 lpd) - s_add_filter didn't ensure enough buffering. This entailed moving the NullEncode/Decode filters to stream.[hc]. (sfilter1.c [1.2]: 2000/03/19 03:15:02 lpd) - The parameters of SubFileDecode filters weren't initialized fully (required by a change in this version). (zfilter.c [1.3]: 2000/03/19 04:03:45 lpd) - The AutoPositionEPSFiles Distiller parameter was misspelled AutoPositionEPSFile. (lib/gs_pdfwr.ps [1.2]: 2000/03/19 05:03:31 lpd) - Enumerating the elements of a dictionary-based parameter list returned garbage for the keys. (iparam.c [1.2]: 2000/03/19 15:13:13 lpd) - .buildfont0 should not check CIDSystemInfo compatibility. The PLRM3 says PostScript interpreters do not make this check, even though the PLRM2 says compatibility is required (!). (zfcmap.c [1.2]: 2000/03/19 16:53:50 lpd) - If log2_transfer_map_size > 8, identity transfer functions returned garbage. The fix requires that if a client wants to set a transfer function to the identity mapping, it must call gx_set_identity_transfer rather than simply setting the procedure to gs_identity_transfer. (zcolor.c [1.2]: 2000/03/19 17:14:47 lpd) - Separation color spaces didn't store the separation name. (zcssepr.c [1.2]: 2000/03/19 17:21:36 lpd) - The addition of the dummy cid_Setup procedure in gs 6.01 was accidentally commented out. (lib/gs_cidfn.ps [1.5]: 2000/03/21 00:11:55 lpd) - The test for whether an CIDFontType 2 outline string was large enough to include prefixed metrics was backwards, which would have caused problems with any font that used MetricsCount. (zfcid.c [1.3]: 2000/03/21 00:43:17 lpd) - A couple of places in the Windows code didn't correctly handle Ghostscript version numbers of the form #.0#. (dwsetup.cpp [1.2]: 2000/03/22 21:45:03 lpd) - In some cases, re-registering an existing font or CIDFont with definefont would cause an invalidfont error. (zbfont.c [1.4], zfont42.c [1.3]: 2000/03/28 18:20:39 lpd) - Re-registering a CIDFont with definefont, or defining a CIDFont with definefont instead of /CIDFont defineresource, caused an invalidfont error or a crash. (lib/gs_cidfn.ps [1.9], lib/gs_fonts.ps [1.4]: 2000/03/28 18:21:50 lpd) - The new C BuildGlyph code for CIDFontType 0 fonts didn't handle GlyphDirectory or Type 2 CharStrings correctly. (lib/gs_cidfn.ps [1.12], zfcid.c [1.8]: 2000/03/31 23:21:57 lpd) - The internaldict "operator" was allocated in local VM, preventing it from being bound into procedures allocated in global VM. (lib/gs_init.ps [1.6]: 2000/04/04 22:16:02 lpd) - If there was a CIDInit ProcSet defined in the filesystem, the code for initializing the built-in CIDInit ProcSet became confused. (lib/gs_cidfn.ps [1.13]: 2000/04/04 22:17:33 lpd) - Fixes several problems in resourceforall and resource loading: the operands of resourceforall were restored even in the case of an error in the client's procedure; the name Instances had special meaning for some Adobe code; resourceforall caused an invalidaccess error if an operand was in local VM but the current VM was global; loading a resource from a file could cause a typecheck error if the file left values on the operand stack. (interp.c [1.3], lib/gs_ccfnt.ps [1.2], lib/gs_res.ps [1.3]: 2000/04/04 22:26:02 lpd) - resourceforall didn't enumerate external (loadable) instances, and would enumerate an instance twice if it had both a local and a global definition. (lib/gs_res.ps [1.4]: 2000/04/05 21:07:02 lpd) - The implementation of resourcestatus wasn't compatible with some badly written code in an Adobe font downloader that assumes that the implementation of resourcestatus in Generic and Font is the same. (lib/gs_res.ps [1.5]: 2000/04/05 21:20:07 lpd) - The just-checked-in fixed for resourceforall didn't work properly for the IdiomSet category. (They probably failed for other categories that had no instances, but we didn't check this.) (lib/gs_res.ps [1.6]: 2000/04/05 21:51:43 lpd) - Some Adobe font downloading code assumed that loading a resource file would never leave extra values on the stack; our implementation didn't ensure this (by popping them if needed). (lib/gs_res.ps [1.8]: 2000/04/06 04:50:28 lpd) - If an alphabetic font defined and used a .notdef character, pdfwrite always converted it to a bitmap. (lib/gs_lgo_e.ps [1.2]: 2000/04/07 02:48:23 lpd) Provides a gs_atan2_degrees procedure to parallel sin and cos. (zmath.c [1.2]: 2000/03/18 23:10:39 lpd) Speeds up string garbage collection by scanning unmodified string regions faster. (igcstr.c [1.2]: 2000/03/18 23:29:32 lpd) Adds the ImagemaskTrapping parameter to the trapping state. (lib/gs_trap.ps [1.2]: 2000/03/18 23:35:53 lpd) Increments the version number to 6.20, in anticipation of the next release. (We do this at the beginning of the development for a release, not the end.) (lib/gs_init.ps [1.4]: 2000/03/19 00:27:22 lpd) Adds a pseudo-encoding for the CFF StandardStrings that represent characters. (lib/gs_cff.ps [1.2], lib/gs_css_e.ps [1.1]: 2000/03/19 00:38:50 lpd) Refactors the code for getting Type 1/2/4 font parameters so it can be used for FDArray entries of CIDFontType 0 fonts. (ifont1.h [1.2], zfont1.c [1.2]: 2000/03/19 02:07:45 lpd) Speeds up Function evaluation slightly, by preallocating space for a reasonable number of operands and results on the C stack rather than always allocating it on the heap. (zfunc.c [1.3]: 2000/03/19 02:16:58 lpd) Adds a public procedure for determining whether a PostScript object is a Function, and if so, returning the pointer to the gs_function_t structure. (ifunc.h [1.2], zfunc.c [1.4]: 2000/03/19 02:22:01 lpd) Splits out the [T]BCP filter interface into a separate file. (zfbcp.c [1.2]: 2000/03/19 02:40:18 lpd) Adds a skip_count parameter to the SubFileDecode filter, giving the number of initial bytes or records to skip over. (Needed for printing FunctionType 4 functions, possibly useful for other things.) (sfilter1.c [1.3]: 2000/03/19 03:20:18 lpd) Replaces the implementation of FunctionType 4 functions at the PostScript language level with one that uses the new library-based facilities. (zdevice2.c [1.2], zfunc4.c [1.2]: 2000/03/19 06:56:23 lpd) Changes the key type returned by parameter list enumeration to include a persistence flag, makes C parameter lists support non-persistent keys, and upgrades GC descriptors so that parameter lists can be used non-transiently; updates implementors of parameter lists to call gs_param_list_init to initialize the common members, which is now required. (iparam.c [1.3]: 2000/03/19 15:16:11 lpd) Makes Separation and DeviceN color spaces convert their tint transform function to a FunctionType 4 Function if possible, for better accuracy and to allow writing in PDF files. (lib/gs_lev2.ps [1.2], lib/gs_ll3.ps [1.2]: 2000/03/19 15:28:34 lpd) Makes st_indexed_map private. Clients must now use the constructor procedure alloc_indexed_map rather than allocating instances directly. (zcsindex.c [1.2]: 2000/03/19 16:37:28 lpd) Refactors the code for building fonts so it can be used for FDArray entries of CIDFontType 0 fonts. (bfont.h [1.2], zbfont.c [1.2]: 2000/03/19 16:45:47 lpd) Adds a .fileposition operator that will read the position even of non-positionable streams, needed for the PDF linearizer. (zfileio.c [1.3]: 2000/03/20 04:30:49 lpd) Starts to move support for CIDFontType 0 and 2 into C code, needed by the PDF writer for handling CID-keyed fonts. Implements GlyphDirectory for CIDFonts. Makes GDBytes and CIDMapOffset optional for CIDFontType 0 fonts that have a GlyphDirectory (not documented in the PLRM, but clearly correct). Implements Adobe 3011 features: integer and dictionary CIDMaps, and the MetricsCount entry, in CIDFontType 2 fonts (but only in the C code, which isn't hooked in yet, not in the PostScript code in gs_cidfn.ps.) (icid.h [1.1], ifont.h [1.2], ifont42.h [1.1], zcid.c [1.2], zfcid.c [1.1], zfcmap.c [1.3], zfont42.c [1.2]: 2000/03/20 19:53:06 lpd) Hooks the new CIDMap code into the BuildGlyph procedure for CIDFontType 2 fonts. (Contrary to a previous log comment, MetricsCount is already hooked in.) Support for CIDFontType 2 fonts is now implemented entirely in C, as for Type 42 fonts. (lib/gs_cidfn.ps [1.6], zfcid.c [1.2]: 2000/03/21 00:32:15 lpd) Extends the C support for CIDFontType 0 fonts to include those with FontType 2 subfonts in the FDArray (an Adobe 3011 addition, specifically for CFF fonts). (ifont2.h [1.1], zfcid.c [1.4], zfont2.c [1.2]: 2000/03/21 07:43:42 lpd) Changes Subr loading for CIDFontType 0 fonts from lazy to immediate, so that C code can be guaranteed access to the Subrs. (In every CIDFontType 0 font that we have seen, SubrCount is 5, so this has no significant time or space cost.) Also adds support for FDBytes > 1 in GlyphDirectory definitions. (lib/gs_cidfn.ps [1.7]: 2000/03/21 20:06:44 lpd) Splits off the ReusableStreamDecode filter as a separate module, since CIDFontType 0 fonts will use it even in LanguageLevels below 3. (lib/gs_frsd.ps [1.1], lib/gs_ll3.ps [1.3], zfrsd.c [1.1]: 2000/03/21 21:34:57 lpd) Makes file streams remember the file name, needed for efficiently implementing reusable streams. (zfile.c [1.3], zfileio.c [1.4]: 2000/03/23 02:13:40 lpd) Changes the new .filename operator to return true/false rather than causing an error; redefines findlibfile in terms of a simpler .libfile operator + .filename. (lib/gs_init.ps [1.5], zfile.c [1.4], zfileio.c [1.5]: 2000/03/23 18:47:17 lpd) Finishes implementing the file case of ReusableStreamDecode. This required adding the ability to restrict file-reading streams to a subfile. (lib/gs_frsd.ps [1.2], sfilter1.c [1.4], zfileio.c [1.6], zfrsd.c [1.2]: 2000/03/24 03:59:42 lpd) Changes the implementation of incrementally loaded CIDFontType 0 fonts to use a ReusableStreamDecode filter, in anticipation of moving the BuildGlyph procedure for these fonts from PostScript to C. (lib/gs_cidfn.ps [1.8], zbfont.c [1.3], zfcid.c [1.5]: 2000/03/27 16:36:24 lpd) Changes the get_outline / glyph_data procedure for getting encoded font outline data to return an indication of whether the outline data were just allocated and can be freed by the client. (This is a possibly non-backward-compatible change.) (zfcid.c [1.6]: 2000/03/28 18:47:02 lpd) Changes the procs structure of gs_type1_data to an in-line structure rather than a pointer to a const structure. (Needed for moving CIDFontType 0 support into C.) (zfont1.c [1.3]: 2000/03/29 22:10:31 lpd) Finishes moving support for CIDFontType 0 fonts from PostScript to C. (ifont.h [1.3], ifont42.h [1.2], lib/gs_cidfn.ps [1.10], zfcid.c [1.7], zfont42.c [1.4]: 2000/03/31 04:55:18 lpd) Allows dictionaries as the value of CIDMap resources. (Also removes an unrelated obsolete comment.) (lib/gs_cidfn.ps [1.11]: 2000/03/31 05:11:30 lpd) Finishes implementing the ability to write CIDFontType 0 CFFs. This involved a surprising number of changes in other font-related files. (ichar1.h [1.2], ifcid.h [1.1], zchar1.c [1.2], zfcid.c [1.9], zfcid0.c [1.1], zfcid1.c [1.1], zfont1.c [1.4]: 2000/04/02 07:38:46 lpd) Makes the .writefont9 operator (used only for testing) available in both DEBUG and PROFILE configurations. (zfcid0.c [1.2]: 2000/04/03 02:37:55 lpd) Extends .forceput to handle arrays as well as dictionaries, required to fix a bug with internaldict. (zdict.c [1.2], zgeneric.c [1.2]: 2000/04/04 22:13:23 lpd) Works around an Adobe code assumption that the default FindResource procedure does *not* call the ResourceStatus procedure if the requested instance is already defined in VM. (lib/gs_res.ps [1.7]: 2000/04/05 23:31:54 lpd) Implements the framework for superexec (but none of the actual access check bypasses). (icontext.c [1.2], icstate.h [1.2], zcontrol.c [1.2]: 2000/04/06 04:40:06 lpd) Extends the undocumented CCRun procedure to take an additional argument, a Private dictionary, required by some Adobe font downloading code. (lib/gs_type1.ps [1.3]: 2000/04/06 05:25:10 lpd)Streams
Fixes problems: - s_add_filter didn't ensure enough buffering. This entailed moving the NullEncode/Decode filters to stream.[hc]. (sfilter.h [1.3], stream.c [1.3], stream.h [1.3]: 2000/03/19 03:15:02 lpd) - When FPU_TYPE <= 0, the image interpolation code lost too much accuracy, producing color streaks in the output. (Fix by DanCoby.) (siscale.c [1.2]: 2000/03/29 20:34:45 lpd) - Fixes a couple of typos in the recently checked-in image interpolation fix. (siscale.c [1.3]: 2000/03/30 06:55:26 lpd) Splits out the [T]BCP filter interface into a separate file. (sbcp.c [1.2], sbcp.h [1.1], sfilter.h [1.2]: 2000/03/19 02:40:18 lpd) Adds a skip_count parameter to the SubFileDecode filter, giving the number of initial bytes or records to skip over. (Needed for printing FunctionType 4 functions, possibly useful for other things.) (sfilter.h [1.4]: 2000/03/19 03:20:18 lpd) Changes the key type returned by parameter list enumeration to include a persistence flag, makes C parameter lists support non-persistent keys, and upgrades GC descriptors so that parameter lists can be used non-transiently; updates implementors of parameter lists to call gs_param_list_init to initialize the common members, which is now required. (spsdf.c [1.2]: 2000/03/19 15:16:11 lpd) Makes file streams remember the file name, needed for efficiently implementing reusable streams. (stream.c [1.4], stream.h [1.4]: 2000/03/23 02:13:40 lpd) Finishes implementing the file case of ReusableStreamDecode. This required adding the ability to restrict file-reading streams to a subfile. (sfxfd.c [1.2], sfxstdio.c [1.2], stream.c [1.5], stream.h [1.5]: 2000/03/24 03:59:42 lpd) Changes a few initializations to suppress warnings from one picky compiler that doesn't like ptr = buf - 1 where buf is an array. (spsdf.c [1.3]: 2000/03/28 02:01:34 lpd)Library
Fixes problems: - Two comments in the file were incorrect. (gsiparm3.h [1.2]: 2000/03/19 02:46:11 lpd) - param_coerce_typed, which works with any parameter list implementation, was incorrectly described as associated with the default implementation. (gsparam.h [1.2]: 2000/03/19 03:37:08 lpd) - TrueType fonts didn't use vhea/vmtx if WMode = 1. Also makes gs_font_type42 subclassable, for implementing CIDFontType 2 fonts, and makes its procedure for getting a glyph's side bearing and width virtual, required to support MetricsCount in CIDFontType 2 fonts. (gstype42.c [1.3], gxfont42.h [1.2]: 2000/03/19 03:58:51 lpd) - ImageType 4 images didn't give an error for out-of-range MaskColor values. The file also had an unnecessary #include. (gximage4.c [1.2]: 2000/03/19 04:10:09 lpd) - If log2_transfer_map_size > 8, identity transfer functions returned garbage. The fix requires that if a client wants to set a transfer function to the identity mapping, it must call gx_set_identity_transfer rather than simply setting the procedure to gs_identity_transfer. (gxclrast.c [1.3], gxcmap.c [1.2], gxfmap.h [1.2]: 2000/03/19 17:14:47 lpd) - Fixes a warning about aliasing produced by one extremely picky compiler. (gsnogc.c [1.2]: 2000/03/22 21:39:32 lpd) - Filling or clipping with ridiculously large (out-of-bounds) coordinates could cause an internal overflow that produced incorrect results. (This is probably not the last such bug.) (gxfill.c [1.2]: 2000/03/30 07:03:59 lpd) Provides a gs_atan2_degrees procedure to parallel sin and cos. (gsmisc.c [1.2], gxfarith.h [1.2]: 2000/03/18 23:10:39 lpd) Improves the 8x8 bitmap "flipping" procedure to take advantage of 32-bit ints. (gsutil.c [1.2]: 2000/03/18 23:16:16 lpd) Adds a public procedure for restricting a color to its legal range. (gscspace.c [1.2], gscspace.h [1.2], gxcspace.h [1.2]: 2000/03/18 23:19:17 lpd) Adds the new ImagemaskTrapping parameter to the trapping state. (gstrap.c [1.2], gstrap.h [1.2]: 2000/03/18 23:26:17 lpd) Increments the version number to 6.20, in anticipation of the next release. (We do this at the beginning of the development for a release, not the end.) (gscdef.c [1.2]: 2000/03/19 00:27:22 lpd) Adds a pseudo-encoding for the CFF StandardStrings that represent characters. (gsccode.h [1.2]: 2000/03/19 00:38:50 lpd) Adds a bit_index procedure to the implementation of device halftones, required for writing halftones in PDF files. (The only implementors are internal ones.) (gxdht.h [1.2], gxhtbit.c [1.2]: 2000/03/19 05:10:55 lpd) Adds a public procedure for getting a palette entry of an Indexed color space, used when writing Indexed color spaces in PDF files. (gscindex.h [1.1], gscolor2.c [1.2], gscolor2.h [1.2]: 2000/03/19 05:20:28 lpd) Reimplements "PostScript calculator" (FunctionType 4) functions entirely in C, to allow them to be written out in PDF files. (gsfunc4.c [1.1], gsfunc4.h [1.1], gsstruct.h [1.2]: 2000/03/19 05:25:53 lpd) Moves gx_device_color_equal to the public API, for detecting redundant color setting when writing PDF files. (gsdcolor.h [1.2], gxdcolor.c [1.2], gxdcolor.h [1.2]: 2000/03/19 06:46:08 lpd) Changes the default value of BufferSpace to 4 Mb. In desktop applications, this is a reasonable value that can substantially improve performance (especially for color printers); embedded applications will want to set BufferSpace themselves in any case. (gdevprn.h [1.2]: 2000/03/19 06:51:13 lpd) Adds virtual procedures for Functions to write their parameters to a parameter list, and to access their data source and subfunctions. This is needed for writing Functions in PDF files. This change is also a prerequisite for the C implemention of FunctionType 4 functions, even though it appears later in the change log. (gsdsrc.h [1.2], gsfunc.c [1.2], gsfunc.h [1.2], gsfunc0.c [1.2], gsfunc3.c [1.2], gsparam.c [1.2], gsparam.h [1.3], gxfunc.h [1.2]: 2000/03/19 07:24:53 lpd) Splits off "vanilla" Functions into separate files, in anticipation of removing them (they were only used to implement PostScript Calculator Functions). (gsfunc.c [1.3], gsfunc.h [1.3], gsfuncv.c [1.1], gsfuncv.h [1.1]: 2000/03/19 07:33:08 lpd) Adds a procedure for allocating a C parameter list. (gscparam.c [1.2], gsparam.h [1.4]: 2000/03/19 15:00:05 lpd) Undoes a premature change that depends on an update not yet checked in. (gscparam.c [1.3]: 2000/03/19 15:07:59 lpd) Changes the key type returned by parameter list enumeration to include a persistence flag, makes C parameter lists support non-persistent keys, and upgrades GC descriptors so that parameter lists can be used non-transiently; updates implementors of parameter lists to call gs_param_list_init to initialize the common members, which is now required. (gscparam.c [1.4], gsparam.c [1.3], gsparam.h [1.5]: 2000/03/19 15:16:11 lpd) Adds a procedure for copying one parameter list to another. (gsparamx.c [1.2], gsparamx.h [1.2]: 2000/03/19 15:35:31 lpd) Records the CTM used for sampling HalftoneType 1 spot functions. This is needed for recognizing the standard spot functions when producing PDF output. Also factors the code for initializing spot functions for the benefit of the PDF writer. (gshtscr.c [1.2], gxdht.h [1.3], gzht.h [1.2]: 2000/03/19 15:43:36 lpd) Adds a proc_data member to the map for Separation and Indexed color spaces. (gscolor2.c [1.3], gxcolor2.h [1.2]: 2000/03/19 16:23:46 lpd) Makes st_indexed_map private. Clients must now use the constructor procedure alloc_indexed_map rather than allocating instances directly. (gscolor2.c [1.4], gscsepr.c [1.2], gxclrast.c [1.2], gxcolor2.h [1.3]: 2000/03/19 16:37:28 lpd) Adds procedures for building and accessing DeviceN color spaces. (gscdevn.c [1.2], gscdevn.h [1.1]: 2000/03/19 17:02:37 lpd) Exports the 'blend' operators of the Type 1 interpreter, for use by the Type 1 / Type 2 font writer. (gstype1.c [1.3], gxtype1.c [1.2], gxtype1.h [1.3]: 2000/03/19 18:46:44 lpd) Starts to move support for CIDFontType 0 and 2 fonts into C code. (These header files are the ones needed to compile the new gdevpsf* files; they don't interact with any existing code.) (gxcid.h [1.1], gxfcid.h [1.1]: 2000/03/20 06:40:22 lpd) Moves font-writing support into a new module (gdevpsf*), changing the source file names. Adds the ability to write CFF fonts, with either Type 1 or Type 2 CharStrings; unfortunately, Acrobat Reader appears not to accept CFF fonts with Type 1 CharStrings. Adds the ability to convert Type 1 CharStrings to Type 2, including optimizing sequences of Type 1 operators into a single Type 2 operator. Implements writing CIDFontType 0 CFF fonts (CIDFonts) [NOT TESTED]. Starts (just barely) to remove more unneeded information from embedded TrueType fonts. (gxttf.h [1.1]: 2000/03/20 07:02:12 lpd) Starts to move support for CIDFontType 0 and 2 into C code, needed by the PDF writer for handling CID-keyed fonts. Implements GlyphDirectory for CIDFonts. Makes GDBytes and CIDMapOffset optional for CIDFontType 0 fonts that have a GlyphDirectory (not documented in the PLRM, but clearly correct). Implements Adobe 3011 features: integer and dictionary CIDMaps, and the MetricsCount entry, in CIDFontType 2 fonts (but only in the C code, which isn't hooked in yet, not in the PostScript code in gs_cidfn.ps.) (gsfcid.c [1.1], gsfcmap.c [1.3], gxfcmap.h [1.2], gxfont1.h [1.2]: 2000/03/20 19:53:06 lpd) Changes a few initializations to suppress warnings from one picky compiler that doesn't like ptr = buf - 1 where buf is an array. (gxclpath.c [1.2]: 2000/03/28 02:01:34 lpd) Changes the get_outline / glyph_data procedure for getting encoded font outline data to return an indication of whether the outline data were just allocated and can be freed by the client. (This is a possibly non-backward-compatible change.) (gxfcid.h [1.2], gxfont42.h [1.3]: 2000/03/28 18:47:02 lpd) Changes the procs structure of gs_type1_data to an in-line structure rather than a pointer to a const structure. (Needed for moving CIDFontType 0 support into C.) (gstype1.c [1.4], gstype2.c [1.3], gxfont1.h [1.3], gxtype1.c [1.3]: 2000/03/29 22:10:31 lpd) Finishes moving support for CIDFontType 0 fonts from PostScript to C. (gxfcid.h [1.3]: 2000/03/31 04:55:18 lpd) Finishes implementing the ability to write CIDFontType 0 CFFs. This involved a surprising number of changes in other font-related files. (gsfcid.c [1.2], gxfcid.h [1.4]: 2000/04/02 07:38:46 lpd)
Version 6.01 (2000-03-17)
This is a bug-fix release for 6.0. This release fixes the following reported bugs: #101555, #101813, #101816, #101818, #101827, #101830, #101871, #101853, #101906, #101949, #101950, #102003, #102004, #102038, #102081, #102936.Incompatible changes
(Platforms) - OpenVMS using VAX C is no longer supported. (OpenVMS with DEC C and gcc are still supported.) (Drivers) - The third argument of psdf_set_color is changed from const char * to const psdf_set_color_commands_t *. (Interpreter) - The non-standard feature of writing dictionaries in binary object output is now disabled by default, but can now be enabled dynamically. (Library) - The definition of TRANSPARENCY_PER_H_P is moved from gdevmrop.h to gsropt.h. - The handling of the source opaque, texture transparent case of RasterOp when TRANSPARENCY_PER_H_P is defined is changed slightly.Documentation
Fixes problems: - Fixes a typo. (man/ps2pdf.1 [1.2]: 2000/03/10 03:11:06 lpd) - When converting PostScript to PDF, selecting /Bicubic as an image DownsampleType caused an error instead of defaulting to /Average. (doc/Ps2pdf.htm [1.2]: 2000/03/10 04:16:09 lpd) - The gs###src.zip and gs###lib.zip files weren't mentioned as being included in distributions; News.htm and Changes.htm weren't mentioned at all. (doc/Release.htm [1.5]: 2000/03/15 07:23:52 lpd) - Fixes a problem producing too much black in the output; also adds support for 5 new printers (H-P Color DeskJet 690, H-P DesignJet 750, and Epson Stylus Color 200). Note that this is user-contributed code. (doc/Devices.htm [1.2]: 2000/03/16 02:01:36 lpd) In ansi2knr, adds user-contributed support for concatenated string literals and character constants, and fixes for a couple of minor bugs. (man/ansi2knr.1 [1.2]: 2000/03/10 03:16:17 lpd) Removes an inappropriate copying notice. (doc/Hershey.htm [1.2]: 2000/03/10 07:03:57 lpd) Clarifies when xdpyinfo and xwininfo are needed. Adds privacy options for problem reports. (doc/Bug-form.htm [1.2]: 2000/03/10 07:06:08 lpd) Adds a new eps2eps utility analogous to ps2ps. (man/eps2eps.1 [1.1], man/ps2ps.1 [1.2]: 2000/03/10 07:51:55 lpd) Updates the documentation on making RPMs, which is no longer supported. (doc/Install.htm [1.2], doc/Make.htm [1.2]: 2000/03/10 07:58:00 lpd) Adds a recommendation to use gcc on SGI platforms. (doc/Make.htm [1.3]: 2000/03/10 07:59:53 lpd) Updates documentation regarding Unix systems that do/don't use libpthread. (doc/Make.htm [1.4]: 2000/03/10 08:01:35 lpd) Removes support for VAX C, which DEC stopped supporting 9 (!) years ago. (doc/Make.htm [1.5], doc/Use.htm [1.2]: 2000/03/10 08:02:59 lpd) Updates the documentation for building Aladdin releases to reflect revised procedures for the Windows executable, and a few other minor changes. (doc/Release.htm [1.2]: 2000/03/10 15:55:39 lpd) Adds the ability to compile on OS/2 with XFree86. (doc/Install.htm [1.3], doc/Make.htm [1.6]: 2000/03/10 19:50:49 lpd) Moves all history for versions 5.n into History5.htm; creates History6.htm for versions 6.n; redefines News.htm as containing only news for the current release; adds (a link to) Changes.htm for the mechanically generated change log. (doc/History5.htm [1.2], doc/History6.htm [1.1], doc/News.htm [1.2], doc/README [1.2], doc/Readme.htm [1.2]: 2000/03/14 06:14:43 lpd) Partially updates the release procedure documentation to reflect the use of SourceForge and CVS. (doc/Release.htm [1.3]: 2000/03/14 06:39:23 lpd) Adds a change log generated mechanically from the CVS logs. Future releases may omit this file (doc/Changes.htm) from their change log. (doc/Changes.htm [1.1], doc/News.htm [1.3]: 2000/03/14 06:48:44 lpd) Revises the release procedures to reflect use of SourceForge, and to separate out the procedures for building Windows executables. (doc/Release.htm [1.4]: 2000/03/15 02:24:58 lpd) Adds information on uninstalling Ghostscript on Windows. (doc/Install.htm [1.4]: 2000/03/15 07:29:53 lpd) Adds the ability to set the ProcessColorModel of the pdfwrite device to /DeviceGray, /DeviceRGB, or /DeviceCMYK. This affects the color space used for fill, stroke, text, and imagemask, and for images that (for whatever reason) can't be written in their specified color space. Note that this is a short-term fix: pdfwrite should output colors in the color space in which they were specified. However, a proper fix will require more significant architectural changes. (doc/News.htm [1.4]: 2000/03/16 01:21:23 lpd) Adds a reference to a third-party Fontmap for the Computer Modern fonts. (doc/Fonts.htm [1.2]: 2000/03/16 04:05:07 lpd) Adds documentation and a makefile entry for Matthew Gelhaus' cdj880 driver. The code will eventually be included in gdevcd8.c, but it is not yet mature enough. (doc/Devices.htm [1.3]: 2000/03/16 08:09:42 lpd) Updates the version number reference in the troff header. (man/ps2pdf.1 [1.3], man/ps2ps.1 [1.3]: 2000/03/17 00:47:08 lpd) Removes the attempted documentation on building Windows executable distributions: it was never correct, and Aladdin will no longer be creating such distributions. Also reorganizes the document slightly and brings the rest of it fully into line with reality. (doc/Release.htm [1.6]: 2000/03/17 04:40:47 lpd) Adds information on building with the Intel C/C++ optimizing compiler (requires the Microsoft Visual C++ environment), and fixes a typo in the link to ftp.cdrom.com. (doc/Make.htm [1.7]: 2000/03/17 17:42:59 lpd) Checks in the first wrap-up for the 6.01 release. (doc/Changes.htm [1.2], doc/History6.htm [1.2], doc/News.htm [1.5]: 2000/03/18 04:13:40 lpd)Procedures
Fixes problems: - The terminating $ on the $Id: line in gsmalloc.c was missing, and dwuninst.rc lacked a $Id: line. (dwuninst.rc [1.2]: 2000/03/10 03:44:33 lpd) - The %ram% IODevice was defined, but should not be (it represents a RAM-based file system, which Ghostscript does not provide). Fix: The type of the %null% IODevice was /FileSystem rather than /Special. (int.mak [1.2]: 2000/03/10 07:02:07 lpd) - The dependency list for coslwxl omitted a $(DD). (contrib.mak [1.2]: 2000/03/10 07:30:54 lpd) - The makefile still referred to a long-gone driver for the DEC LA70. (contrib.mak [1.3]: 2000/03/10 07:32:43 lpd) - The Unix install process tried to make links without deleting them first. (unixinst.mak [1.2]: 2000/03/10 07:49:21 lpd) - The Watcom compiler switches didn't force enums to occupy a full int, leading to execution errors because the code casts (enum *) pointers to (int *). (wccommon.mak [1.2]: 2000/03/10 08:15:31 lpd) - The Windows zip archive didn't include font metrics files. (This change only fixes the build procedure: it doesn't actually update the currently released zip archive.) (winint.mak [1.2]: 2000/03/10 08:17:06 lpd) - the "all architectures" build and test script hadn't been updated to use different STDLIBS values depending on where the platform provides the pthreads library. (all-arch.mak [1.2]: 2000/03/10 15:40:43 lpd) - The documentation for building with pthreads on FreeBSD hadn't been updated. (unix-gcc.mak [1.2], unixansi.mak [1.2], unixtrad.mak [1.2]: 2000/03/10 15:44:01 lpd) - gsmalloc.c didn't include the prototype for gs_exit(), which it calls. (lib.mak [1.2]: 2000/03/10 15:53:08 lpd) Because of rampant confusion, disagreement, and lack of standardization, removes the RPM-related spec and patch files. (gs-fonts.rps [1.2], gs.rps [1.2], rpm-conf.dif [1.2]: 2000/03/10 03:22:04 lpd) Increases the stack size for the PC platforms, since a user had reported that the OS/2 stack size was too small. (dw32c.def [1.2], dwmain32.def [1.2], gsos2.def [1.2]: 2000/03/10 03:33:21 lpd) Updates the Brother HL7xx drivers with a new user-contributed version, plus a couple of minor fixes. (contrib.mak [1.4]: 2000/03/10 07:33:44 lpd) Adds a new eps2eps utility analogous to ps2ps. (unixinst.mak [1.3]: 2000/03/10 07:51:55 lpd) Removes support for VAX C, which DEC stopped supporting 9 (!) years ago. (openvms.mak [1.2], openvms.mmk [1.2]: 2000/03/10 08:02:59 lpd) Updates all makefiles to the current libpng version, 1.0.5. (bcwin32.mak [1.2], dvx-gcc.mak [1.2], msvc32.mak [1.2], msvclib.mak [1.2], os2.mak [1.2], ugcclib.mak [1.2], unix-gcc.mak [1.3], unixansi.mak [1.3], unixtrad.mak [1.3], watc.mak [1.2], watclib.mak [1.2], watcw32.mak [1.2]: 2000/03/10 15:48:58 lpd) Updates the version # to 6.01, and the version date. (version.mak [1.2]: 2000/03/10 17:18:29 lpd) Adds the ability to compile on OS/2 with XFree86. (os2.mak [1.3]: 2000/03/10 19:50:49 lpd) Moves all history for versions 5.n into History5.htm; creates History6.htm for versions 6.n; redefines News.htm as containing only news for the current release; adds (a link to) Changes.htm for the mechanically generated change log. (unixinst.mak [1.4], version.mak [1.3]: 2000/03/14 06:14:44 lpd) Adds entries for ibm-rs6000-aix-4.3, sgi-mips-irix6.5-64bit, and sun-sparc-solaris-64bit. (all-arch.mak [1.3]: 2000/03/15 18:38:29 lpd) Adds the ability to set the ProcessColorModel of the pdfwrite device to /DeviceGray, /DeviceRGB, or /DeviceCMYK. This affects the color space used for fill, stroke, text, and imagemask, and for images that (for whatever reason) can't be written in their specified color space. Note that this is a short-term fix: pdfwrite should output colors in the color space in which they were specified. However, a proper fix will require more significant architectural changes. (version.mak [1.4]: 2000/03/16 01:21:24 lpd) Adds documentation and a makefile entry for Matthew Gelhaus' cdj880 driver. The code will eventually be included in gdevcd8.c, but it is not yet mature enough. (contrib.mak [1.5]: 2000/03/16 08:09:42 lpd) Adds a missing dependency of gdevpdft.o on gxfont42.h. (devs.mak [1.2]: 2000/03/17 02:59:26 lpd) Adds a disclaimer of responsibility for the makefile section for creating distribution archives, which Aladdin is no longer maintaining. (winint.mak [1.3]: 2000/03/17 03:01:58 lpd) Checks in the first wrap-up for the 6.01 release. (unix-gcc.mak [1.4], version.mak [1.5]: 2000/03/18 04:13:40 lpd)Utilities
Fixes problems: - The loader for the stochastic halftone incorrectly assumed that the resource file left the resource on the stack, causing a stackunderflow error. (lib/stocht.ps [1.2]: 2000/03/10 03:34:44 lpd) - The ps2pdf*.bat scripts didn't set PS2PDFSW to the empty string if there were no arguments, causing the same file to be processed again. (lib/ps2pdf12.bat [1.2], lib/ps2pdf13.bat [1.2]: 2000/03/10 07:40:00 lpd) - Fixes a typo in the fix for putting stdout in binary mode. (gp_ntfs.c [1.3]: 2000/03/18 01:15:16 lpd) - For printer devices, a non-null definition for OutputFile was required even on platforms that had a default printer (as implemented by gp_open_printer for that platform). (gp_os9.c [1.2], gp_unix.c [1.2], gp_vms.c [1.2]: 2000/03/18 01:45:16 lpd) In ansi2knr, adds user-contributed support for concatenated string literals and character constants, and fixes for a couple of minor bugs. (ansi2knr.c [1.2]: 2000/03/10 03:16:17 lpd) Updates the pf2afm.ps utility with a revised version from its authors. (lib/pf2afm.ps [1.2]: 2000/03/10 03:35:37 lpd) Adds a new eps2eps utility analogous to ps2ps. (lib/eps2eps [1.1], lib/eps2eps.bat [1.1]: 2000/03/10 07:51:55 lpd) Removes a temporary file that was included in the fileset by mistake. (lib/history [1.2]: 2000/03/10 08:18:36 lpd) Changes the ps2pdf MS Windows / MS-DOS scripts to use temporary files to avoid the absurdly low limits on the length of a command line and the total size of environment variable definitions. (lib/ps2pdf.bat [1.2], lib/ps2pdf12.bat [1.3], lib/ps2pdf13.bat [1.3], lib/ps2pdfwr.bat [1.2], lib/ps2pdfxx.bat [1.1]: 2000/03/14 20:20:20 lpd) On Windows, puts stdout into binary mode as well as stdin, to allow piping printer output through stdout (not a good idea, but it should be supported as well as on other platforms). (gp_ntfs.c [1.2]: 2000/03/17 06:22:59 lpd)Drivers
Fixes problems: - When converting PostScript to PDF, selecting /Bicubic as an image DownsampleType caused an error instead of defaulting to /Average. (gdevpsdf.h [1.2], gdevpsdi.c [1.2], gdevpsdp.c [1.2]: 2000/03/10 04:16:09 lpd) - The mswinpr2 driver didn't handle setting BitsPerPixel to the same value when the device was already open, possibly causing an error on restore or grestore. (gdevwpr2.c [1.2]: 2000/03/10 04:26:07 lpd) - When operating in buffered mode (MaxBitmap > 0), the X driver sometimes failed to copy all of the updated area to the screen. (gdevx.c [1.2], gdevx.h [1.2], gdevxini.c [1.2], gdevxxf.c [1.2]: 2000/03/10 06:56:27 lpd) - The [e]pswrite driver produced invalid output if the input file didn't end with a showpage. Also cleans up some formatting and removes a redundant test. (gdevps.c [1.2]: 2000/03/10 07:44:27 lpd) - Fixes a problem producing too much black in the output; also adds support for 5 new printers (H-P Color DeskJet 690, H-P DesignJet 750, and Epson Stylus Color 200). Note that this is user-contributed code. (gdevupd.c [1.2], lib/bjc610a0.upp [1.2], lib/bjc610a1.upp [1.2], lib/bjc610a2.upp [1.2], lib/bjc610a3.upp [1.2], lib/bjc610a4.upp [1.2], lib/bjc610a5.upp [1.2], lib/bjc610a6.upp [1.2], lib/bjc610a7.upp [1.2], lib/bjc610a8.upp [1.2], lib/bjc610b1.upp [1.2], lib/bjc610b2.upp [1.2], lib/bjc610b3.upp [1.2], lib/bjc610b4.upp [1.2], lib/bjc610b6.upp [1.2], lib/bjc610b7.upp [1.2], lib/bjc610b8.upp [1.2], lib/cdj550.upp [1.2], lib/cdj690.upp [1.1], lib/cdj690ec.upp [1.1], lib/dnj750c.upp [1.1], lib/dnj750m.upp [1.1], lib/ras32.upp [1.2], lib/stc.upp [1.2], lib/stc1520h.upp [1.2], lib/stc2.upp [1.2], lib/stc200_h.upp [1.1], lib/stc2_h.upp [1.2], lib/stc2s_h.upp [1.2], lib/stc500p.upp [1.2], lib/stc500ph.upp [1.2], lib/stc600ih.upp [1.2], lib/stc600p.upp [1.2], lib/stc600pl.upp [1.2], lib/stc800ih.upp [1.2], lib/stc800p.upp [1.2], lib/stc800pl.upp [1.2], lib/stc_h.upp [1.2], lib/stc_l.upp [1.2], lib/stcany.upp [1.2]: 2000/03/16 02:01:36 lpd) - The X driver's algorithm for deciding when to update the screen was changed several times between 5.50 and 6.0, and one of the more recent changes caused it to copy many more pixels to the screen than necessary if the file was making marks on the page in widely separated places. (gdevx.c [1.3]: 2000/03/17 07:35:43 lpd) - In the X driver, the full-page buffer controlled by -dMaxBitmap= wasn't allocated with a stable allocator, possibly leading to memory access errors if save/restore were used. (gdevxini.c [1.3]: 2000/03/18 04:11:59 lpd) Updates the Brother HL7xx drivers with a new user-contributed version, plus a couple of minor fixes. (gdevhl7x.c [1.2]: 2000/03/10 07:33:44 lpd) Enhances the [e]pswrite driver to handle Indexed color spaces over Device color spaces, only with the standard Decode. (gdevps.c [1.3]: 2000/03/10 07:45:50 lpd) Adds the ability to set the ProcessColorModel of the pdfwrite device to /DeviceGray, /DeviceRGB, or /DeviceCMYK. This affects the color space used for fill, stroke, text, and imagemask, and for images that (for whatever reason) can't be written in their specified color space. Note that this is a short-term fix: pdfwrite should output colors in the color space in which they were specified. However, a proper fix will require more significant architectural changes. (gdevpsdf.c [1.2], gdevpsdf.h [1.3]: 2000/03/16 01:21:24 lpd) Adds two more user-contributed 'uniprint' printer parameter sets: Epson Stylus Color 640, and a generic Epson Stylus Color in high resolution mode (720x720 dpi). (lib/stc640p.upp [1.1], lib/stcany_h.upp [1.1]: 2000/03/16 02:03:40 lpd)PDF writer
Fixes problems: - In-line images emitted an extra 'q' (gsave), causing the CTM to become incorrect, entries to pile up on the dictionary stack, and an invalidrestore error to occur at the end of the page. (gdevpdfi.c [1.2]: 2000/03/10 03:47:37 lpd) - The change in 5.99 to work around Acrobat Reader's 32K limit on user space coordinates caused all 0-width rectangles to disappear, which had major effects on some files. (gdevpdfd.c [1.2]: 2000/03/10 03:48:10 lpd) - Incrementally downloaded TrueType fonts produced truncated Widths tables in the output. We have patched this with a ******HACK****** that causes such fonts to be converted to bitmaps: the correct fix (to delay determining the range of valid characters until the font is written) is too large a change to make in a bug fix release. (gdevpdft.c [1.2]: 2000/03/10 03:48:48 lpd) Adds the ability to set the ProcessColorModel of the pdfwrite device to /DeviceGray, /DeviceRGB, or /DeviceCMYK. This affects the color space used for fill, stroke, text, and imagemask, and for images that (for whatever reason) can't be written in their specified color space.

Fixes problems: - When interpreting a PDF file, the Install page device procedure got more and more deeply nested after every page, eventually causing an execstackoverflow. (lib/pdf_main.ps [1.2]: 2000/03/10 03:56:11 lpd) - When interpreting a PDF file, text drawing operators didn't reset the text position, so strings could get displayed on top of each other. (bug introduced by a fix in 5.98) (lib/pdf_ops.ps [1.2]: 2000/03/10 03:57:03 lpd) - When interpreting a PDF file, substituted small-cap fonts were created with incorrect scaling. (lib/pdf_font.ps [1.2]: 2000/03/10 03:57:50 lpd) Cleans up some formatting. (lib/pdf_base.ps [1.2]: 2000/03/10 03:58:14 lpd)Interpreter
Fixes problems: - There were extraneous 'def' commands that caused definitions to be made in the wrong dictionary. (lib/gs_ttf.ps [1.2]: 2000/03/10 03:31:39 lpd) - If an error occurred while loading a font, it wouldn't produce an error message. (This is a 'fix' of a 'fix' of a 'fix': it might well break something else.) (lib/gs_type1.ps [1.2]: 2000/03/10 03:37:14 lpd) - When reading the strings of a binary object sequence, having to get more data from a procedure-based stream sometimes caused a syntaxerror. Fix: If the reserved (0) field in binary objects or binary object sequences was not 0, no syntaxerror occurred. (iscanbin.c [1.2]: 2000/03/10 03:38:50 lpd) - The code for handling execstackoverflow errors didn't cut back the stack correctly, possibly causing invalid memory accesses if an incorrect attempt was made to run a cleanup procedure. (interp.c [1.2]: 2000/03/10 04:04:38 lpd) - Writing of dictionaries in binary object output, a non-standard extension, was enabled by default, and also had to be enabled at startup time if it was ever going to be used. Fix: Binary error messages caused an error if the command wasn't of a type that printobject could handle. We now do what the Adobe implementations appear to do in this case, namely, convert the object with cvs. (lib/gs_btokn.ps [1.2]: 2000/03/10 04:27:31 lpd) - CloseSource and CloseTarget were effectively ignored for Flate and LZW filters with a Predictor, and for the DCT filters. (ifilter.h [1.2], zfdctd.c [1.2], zfdcte.c [1.2], zfdecode.c [1.2], zfilter.c [1.2], zfilter2.c [1.2]: 2000/03/10 04:32:51 lpd) - findlibfile didn't handle %iodevice% prefixes correctly. (zfile.c [1.2]: 2000/03/10 04:35:08 lpd) - fileposition didn't give an error for filters or non-seekable streams. (zfileio.c [1.2]: 2000/03/10 04:35:53 lpd) - Images with input from a file or filter demanded 1 byte of data too many, sometimes causing the last line of the image to be dropped. (bug probably introduced in 6.0) (zimage.c [1.2]: 2000/03/10 04:37:02 lpd) - The check for a show within a cshow procedure for a CID font was wrong. Fix: Character widths in CIDFontType 0 fonts were ignored (!). Adds a .glyphwidth operator to support correct handling of character widths for CID fonts. Adds a glyphwidth procedure to the library, like glyphshow and glyphpath, in order to support correct handling of widths for CID fonts. (ichar.h [1.2], lib/gs_cidfn.ps [1.2], zchar.c [1.2], zcharx.c [1.2]: 2000/03/10 04:41:47 lpd) - resourcestatus for fonts was broken. (lib/gs_res.ps [1.2]: 2000/03/10 04:54:15 lpd) - Fixes incorrect documentation of several procedures. (lib/gs_fonts.ps [1.2]: 2000/03/10 07:00:28 lpd) - The %ram% IODevice was defined, but should not be (it represents a RAM-based file system, which Ghostscript does not provide). Fix: The type of the %null% IODevice was /FileSystem rather than /Special. (ziodev2.c [1.2]: 2000/03/10 07:02:07 lpd) - Directly-loaded TrueType fonts (including embedded TrueType fonts in PDF files) could get confused with each other in the cache, because their XUIDs were based on the font checksum field, which some fonts don't have set correctly. (lib/gs_ttf.ps [1.3]: 2000/03/16 07:38:07 lpd) Adds a new example file, a 3-D synthetic image. (examples/doretree.ps [1.1]: 2000/03/10 04:00:45 lpd) Adds implementations of the devforall, devstatus, and diskonline compatibility operators. (lib/gs_statd.ps [1.2]: 2000/03/10 04:01:55 lpd) Some Adobe CIDFonts include a line /Setup /cid_Setup load def that apparently is intended only to prevent the fonts from being loaded by a standard PostScript interpreter (as opposed to ATM or a special font loader), since cid_Setup is not defined anywhere and Setup is never referenced; this change adds a dummy definition of cid_Setup to work around this. (lib/gs_cidfn.ps [1.3]: 2000/03/10 04:53:25 lpd) Updates the version # to 6.01, and the version date. (lib/gs_init.ps [1.2]: 2000/03/10 17:18:29 lpd) Changes the default undercolor removal and black generation functions back from f(k) = k to f(k) = 0. This fixes some, but not all, of the reported problems with color inkjet output in 6.0. (lib/gs_init.ps [1.3]: 2000/03/10 18:47:31 lpd) On Windows, puts stdout into binary mode as well as stdin, to allow piping printer output through stdout (not a good idea, but it should be supported as well as on other platforms). (dwmainc.cpp [1.2]: 2000/03/17 06:22:59 lpd)Streams
Changes the sbuf_min_left macro to a procedure for readability and in preparation for later revision. (stream.c [1.2], stream.h [1.2]: 2000/03/10 03:40:13 lpd)Library
Fixes problems: - (%os%) currentdevparams didn't return (fixed) values for InitializeAction, Mounted, Removable, Searchable, SearchOrder, and Writeable, or (meaningful) values for BlockSize, Free, and LogicalSize. Currently, the latter values are dummies. (gsiodev.c [1.2]: 2000/03/10 03:43:06 lpd) - The terminating $ on the $Id: line in gsmalloc.c was missing, and dwuninst.rc lacked a $Id: line. (gsmalloc.c [1.2]: 2000/03/10 03:44:33 lpd) - RasterOps with source transparency = 0, texture transparency = 1 didn't match the (very peculiar) H-P specification even if TRANSPARENCY_PER_H_P was defined. (gdevdrop.c [1.2], gdevmrop.h [1.2], gsropt.h [1.2]: 2000/03/10 04:06:15 lpd) - The prototype for gs_exit() was not included even though gs_exit() was called. Fix: A cast discarded const unnecessarily. (gsalloc.c [1.2]: 2000/03/10 04:08:23 lpd) - The type of the %pipe% IODevice was /FileSystem, whereas it should be /Special. (gdevpipe.c [1.2]: 2000/03/10 04:13:57 lpd) - An incorrectly formatted procedure couldn't be converted correctly by ansi2knr. (gxidata.c [1.2]: 2000/03/10 04:30:58 lpd) - The check for a show within a cshow procedure for a CID font was wrong. Fix: Character widths in CIDFontType 0 fonts were ignored (!). Adds a .glyphwidth operator to support correct handling of character widths for CID fonts. Adds a glyphwidth procedure to the library, like glyphshow and glyphpath, in order to support correct handling of widths for CID fonts. (gschar.c [1.2], gschar.h [1.2], gstext.c [1.2], gstext.h [1.2]: 2000/03/10 04:41:47 lpd) - The description of the value returned by code_map_decode_next in *pchr was incorrect. (documentation bug only) (gsfcmap.c [1.2]: 2000/03/10 07:03:09 lpd) - Fixes a problem producing too much black in the output; also adds support for 5 new printers (H-P Color DeskJet 690, H-P DesignJet 750, and Epson Stylus Color 200). Note that this is user-contributed code. (gsargs.h [1.2]: 2000/03/16 02:01:36 lpd) - The code for Axial shadings incorrectly assumed that if the shading axis was horizontal or vertical in user space, it was also horizontal or vertical in device space: this caused incorrect results when the CTM wasn't orthogonal. (gxshade1.c [1.2]: 2000/03/17 08:17:55 lpd) - For printer devices, a non-null definition for OutputFile was required even on platforms that had a default printer (as implemented by gp_open_printer for that platform). (gp.h [1.2], gsdevice.c [1.2]: 2000/03/18 01:45:16 lpd) Clears the glyf and loca offsets in TrueType fonts that lack these tables, so that clients who care can tell whether the font is being downloaded incrementally. (gstype42.c [1.2]: 2000/03/10 03:45:29 lpd) Changes a few macro definitions to work around over-zealous compiler warnings. (gstype1.c [1.2], gstype2.c [1.2], gxtype1.h [1.2]: 2000/03/10 04:29:37 lpd) Changes the default undercolor removal and black generation functions back from f(k) = k to f(k) = 0. This fixes some, but not all, of the reported problems with color inkjet output in 6.0. (gxdcconv.c [1.2]: 2000/03/10 18:47:31 lpd)

Fixes problems: - Building on BSDI didn't work. The simplest way to fix this was to change the linking of the pthreads library on Unix platforms to be included in STDLIBS rather than the "sync" implementation. (fix contributed by a user) (lib.mak, unix-gcc.mak, unixansi.mak, unixtrad.mak) - Once again, some runtime files weren't installed. (unixinst.mak) - Building the self-extracting executable didn't work. (winint.mak) Updates the user-contributed all-architectures makefile. (all-arch.mak)Utilities
Fixes problems: - A needed #include was missing. (geninit.c) - There were signed/unsigned char mismatches. (genht.c, geninit.c) - The MacOS compiler imposes a 32K limit on the size of a stack frame: we changed the code to use malloc/free. (geninit.c) Removes an unnecessary variable. (echogs.c) Adds a file that attempts to test the image operators exhaustively. (lib/image-qa.ps, unixinst.mak) Enhances the prfont.ps utility to print CIDFonts. (lib/prfont.ps) Adds a utility file that patches the PDF interpreter to allow garbage after the %%EOF (or the %%EOF to be missing completely). (lib/pdfeof.ps)Drivers
Fixes problems: - The X driver compared too many bits of color value, leading to unnecessary halftoning. (bug introduced by a fix in 5.99) (gdevxcmp.c) - Output from the pswrite driver got a dictfull error on Level 1 printers. (gdevps.c) - Anti-aliasing had stopped working on MS Windows and OS/2. (bug probably introduced in 5.65) (gdevmswn.c, gdevpm.c)Platforms
Adds a conditional definition of PTHREAD_CREATE_DETACHED for old versions of the pthreads library. (gp_psync.c) Updates the Microsoft Visual C++ library makefile for VC++ 6. (msvclib.mak) Updates some copyright dates. (winint.mak, dwsetup.rc)Fonts
Updates the URW fonts to include the expanded Adobe character set, including many Eastern European accented characters. (doc/New-user.htm) Removes a 'readonly' that inconvenienced the authors of ttf2pf. (lib/gs_ttf.ps)PDF writer
Fixes problems: - The Dest key was deleted from GoTo and GoToR link annotation pdfmarks. (gdevpdfm.c) - {name} references were substituted even in stream data for the /PUT pdfmark. (gdevpdfm.c) - The revision number was sometimes printed incorrectly if its fraction part was zero. (gdevpdf.c) - Embedded Multiple Master font instances weren't identified as MMType1 rather than Type1. (gdevpdff.h, gdevpdff.c, gdevpdft.c, gdevpdfw.c) - The test against MaxSubsetPct was incorrect when the percentages were equal. (gdevpdfw.c) - Font registrations weren't removed when the device was closed. (gdevpdff.h, gdevpdfx.h, gdevpdff.c, gdevpdfw.c) - Multiple /OBJ pdfmarks with the same name caused an error. For Distiller compatibility, we now allow this if the type is the same, even though the pdfmark specification doesn't say anything about this being legal. (gdevpdfm.c) Removes an unnecessary variable. (gdevpdff.c, gdevpdfr.c) Disables embedding Multiple Master font instances, since Acrobat Reader doesn't accept what appear to be correct output and we don't have time before the release to track down the problem. (gdevpdft.c)Interpreter (PDF)
Factors some code to allow patching the PDF reader to allow garbage after the %%EOF (or the %%EOF to be missing completely). (lib/pdf_main.ps)Interpreter
Fixes problems: - Type 1 fonts with non-standard OtherSubrs had stopped working. (bug introduced since 5.60) (zchar1.c) - usecmap didn't work. (lib/gs_cmap.ps) - The glyph_info procedure for Type 1 fonts didn't take Metrics[2] or CDevProc into account. (zchar1.c, zfont1.c) - The multiple-data-source case of images was broken. (bug introduced in 5.99) (zimage.c) - If a page device Install procedure caused an error, things could be left in an inconsistent state. (lib/gs_setpd.ps) - Using a DeviceN color space could access uninitialized data in a color value. (zcsdevn.c) - DeviceN images with procedure data sources were broken. (zimage.c) - Images with a procedure data source could terminate prematurely if their processing was interrupted. (zimage.c) - The garbage collector only marked half the name table sub-tables, and attempted to mark an equal number of invalid pointers, leading to invalid accesses or memory corruption. (iname.c) Removes an unused variable. (zmisc.c)Streams
Fixes problems: - sgets didn't reset the cursor pointers, so sgets into a client buffer followed by sseek (for some kinds of streams, including files) could get confused. (stream.c)Library
Fixes problems: - A 'const' qualifier was omitted, leading to a type mismatch. (gxclrast.c) - The revision number was sometimes printed incorrectly if its fraction part was zero. (gsmisc.c) - gs_image_next returned the wrong value in *pused if it incremented the plane number. (bug introduced in 5.99) (gsimage.c) - Only the last of the data_x and raster values in the local 'planes' array in gs_image_next_planes were initialized. (bug introduced in 5.99) (gsimage.c) - The multiple-data-source case of images was broken. (bug introduced in 5.99) (gsimage.h, gsimage.c) - ImageType 3 images with unequal scaling for the mask and data didn't work. (We thought they once did, but it appears they never have.) (gximage3.c) - Images with 12-bit samples treated a Decode entry of [1 0] the same as [0 1]. (Other, general Decode entries worked correctly.) (gxipixel.c) - ImageType 3 images didn't work if processing was ever interrupted for remapping a color. (gximage3.c) - Images in DeviceN color spaces with 12-bit samples didn't work. (gxi12bit.c, gxidata.c) - Images in DeviceN color spaces could fail to render properly because the interruption of rendering left a half-built entry in an internal cache. (gxi12bit.c, gxicolor.c) - Images with non-idempotent RasterOps in 1-component DeviceN color spaces didn't render properly, because the same pixel was rendered multiple times after a color remapping interruption. (gximono.c) - The fast case of masked images caused a crash if invoked without an imager state. (gximono.c) - Flushing buffered image data could cause coordinate bookkeeping to get out of sync. (gxidata.c) - ImageType 3, InterleaveType 2 images sometimes failed to render the last row. (gximage3.c) - The fix in 5.88 for resizing large objects had a bug itself. (gsalloc.c) - Whan banding, if a client supplied more data than necessary for an image, the client was told (incorrectly) that all of the data was used. (fix from Artifex) (gxclimag.c) - Null patterns caused a crash. (bug probably introduced by changes to support PatternType 2) (gspcolor.c) - On hand-initialized memory devices where line_ptrs[0] != base, monobit RasterOps could cause invalid or stray memory accesses. (gdevmr1.c) Removes an unnecessary variable. (gdevppla.c, gsfont.c) Adds the ability to call a specified procedure when unregistering notification, needed for removing PDF font registrations. (gsnotify.h, gsnotify.c) Updates the copyright year. (gscdef.c)
