Fixes problems: - cvs2hist no longer worked in Python 2.1 and later: the regex and regsub modules were superseded by re, and append() no longer accepted multiple arguments to create a tuple. The fixes are backward compatible for all versions of Python from 1.5 on. (toolbin/cvs2hist.py [1.7]: 2001/09/23 04:45:10 lpd) - The previous update to make cvs2hist use Python's re module rather than the obsolete regex and regsub modules didn't change the code to use match objects when necessary. Finishes fixing SourceForge #462777. (toolbin/cvs2hist.py [1.8]: 2001/09/23 20:43:16 lpd) - Some print statements for debugging were accidentally left in the code. (toolbin/cvs2hist.py [1.9]: 2001/09/23 21:05:12 lpd) - Committing in . Modified Files: gs/src/gp_stdia.c gs/src/openvms.mmk gs/src/ziodevs.c patches for OpenVMS (openvms.mmk [1.10]: 2001/09/24 10:47:06 joukj) - Fixes for stdin as a result of using callouts. Use unbuffered read, not non-blocking read. Change gp_stdin_read to use file pointer not handle. Remove gp_stdin_init since we don't need to set non-blocking. Change gp_stdin.c to use fread/fwrite to be more portable. Flush redirected stdout correctly. Added casts to fix compiler warnings in dxmain.c. Corrected header dependencies. Fixes SourceForge bug #467787. (dvx-tail.mak [1.5], macos-mcp.mak [1.3], openvms.mak [1.16], openvms.mmk [1.11], os2.mak [1.19], unix-aux.mak [1.5], watc.mak [1.16], winlib.mak [1.12]: 2001/10/12 21:37:08 ghostgum) - Committing in . Modified Files: gs/src/openvms.mmk OpenVMS needs target : sources ^ this space is realy needed. Otherwise MMS/MMK chokes on it!!!! (openvms.mmk [1.12]: 2001/10/15 10:24:21 joukj) - When building gsx and gsc, use the GS makefile macro as the shared library name to link against, not a hard coded gs. (unix-dll.mak [1.6]: 2001/10/17 10:11:23 ghostgum) - Removes cheq.ps from list of example files installed. (unixinst.mak [1.20]: 2001/10/17 19:48:36 raph) - uses concrete color space of alternate color space, rather than simply alternate color space, to determine target color space for concretizing /All colors. Fixes regression of non-sepqxd2distiller.pdf, for which those color spaces differed. (gscsepr.c [1.13]: 2001/10/21 06:02:21 raph) - Updates icclib to version 2.0, and integrates icclib changes. In particular, icclib now accesses Ghostscript streams through the clean icmFile object interface, rather than previous hack. Removes remnants of previous hack, including gs_stdio.h header file and sread() and swrite() functions in stream.c. (lib.mak [1.53]: 2001/10/19 21:52:50 raph) - Documentation and version number change in preparation for 7.03 release. (version.mak [1.36]: 2001/10/20 08:44:31 raph) - Updates default MSVC_VERSION to 6. (msvc32.mak [1.20]: 2001/10/20 08:45:39 raph)Utilities

Fixes SourceForge bug #465214. (dxmainc.c [1.3]: 2001/09/28 22:04:03 ghostgum) - If gtk+ GUI can't be initialised, disable display device. This allows gsx to be used without an X display. Partial fix for SourceForge bug #450933. (dxmain.c [1.5]: 2001/10/12 11:10:37 ghostgum) - Fixes for stdin as a result of using callouts. Use unbuffered read, not non-blocking read. Change gp_stdin_read to use file pointer not handle. Remove gp_stdin_init since we don't need to set non-blocking. Change gp_stdin.c to use fread/fwrite to be more portable. Flush redirected stdout correctly. Added casts to fix compiler warnings in dxmain.c. Corrected header dependencies. Fixes SourceForge bug #467787. (dxmain.c [1.6], dxmainc.c [1.4], gp_stdia.c [1.3], gp_stdin.c [1.2]: 2001/10/12 21:37:08 ghostgum) - Proposed log message: Fix: Callout implementation of %stdin, %stdout and %stderr now correctly allocates the streams in system memory. This avoids a crash during garbage collection seen during frequent open/close of stderr.. Fixes SourceForge bugs #427316, #442477. (ziodevsc.c [1.3]: 2001/10/15 21:44:42 ghostgum) - When using STDIO_IMPLEMENTATION=, call gp_stdin_read with a file pointer, not a file handle. (ziodevs.c [1.5]: 2001/10/17 21:12:44 ghostgum) - Use unbuffered read within gtk+ handler instead of using non-blocking read. While waiting for stdin, allow gtk main loop to block to avoid wasting CPU. (dxmain.c [1.7]: 2001/10/20 08:22:05 ghostgum)Drivers
Fixes problems: - If "distiller" image compression options were changed in the middle of a file, the parameter list holding them might not be set back to read mode when using them to compress an image, causing an error. Fixes SourceForge #464938. (gdevpsdi.c [1.15]: 2001/09/25 22:00:44 lpd) - bmp16 and png16 devices now create 4 bit/pixel bitmaps instead of 8. bmp256 and png256 devices now use dci values which match the color mapping functions. (gdevbmp.c [1.4], gdevpng.c [1.4]: 2001/09/28 22:06:21 ghostgum) - Don't omit zero length deltas when stroking so that linecap will be produced by resulting PS or EPS file. SourceForge bug #466162. (gdevps.c [1.19]: 2001/09/28 23:18:46 rayjj) - Fixes for stdin as a result of using callouts. Use unbuffered read, not non-blocking read. Change gp_stdin_read to use file pointer not handle. Remove gp_stdin_init since we don't need to set non-blocking. Change gp_stdin.c to use fread/fwrite to be more portable. Flush redirected stdout correctly. Added casts to fix compiler warnings in dxmain.c. Corrected header dependencies. Fixes SourceForge bug #467787. (gdevsppr.c [1.5]: 2001/10/12 21:37:08 ghostgum) - When the display device fails to allocate memory for the bitmap, set the memory device width and height to zero to prevent drawing on it. Always call the display_size callback to prevent a lockup in the caller, and if there is no memory tell the caller that the width and height are zero. Add some casts to remove compiler warnings. Fixes SourceForge bug #430879. (gdevdsp.c [1.5]: 2001/10/12 21:41:25 ghostgum) - Syncs with hpijs version 0.97, and fixes a documentation bug. (gdevhpij.c [1.3]: 2001/10/19 04:20:07 raph)PDF writer
Fixes problems: - pdfwrite didn't set the orig_matrix of standard fonts, sometimes causing re-encoded characters to be written with a width of 0. Bug introduced by fix for #439474, gdevpdff.c [1.19]. Fixes SourceForge #463400. (gdevpdff.c [1.22]: 2001/10/05 05:40:41 lpd) - pdfwrite allowed AutoRotatePages to override DSC comments rather than vice versa, and it interpreted "Portrait" in a DSC orientation comment as "don't rotate" rather than as "rotate if necessary so that width < height." Fixes SourceForge #467259, although the result is not what the submitter wanted. (gdevpdf.c [1.38], gdevpdfp.c [1.19], gdevpdfx.h [1.34]: 2001/10/07 05:33:11 lpd)PDF Interpreter
Fixes problems: - Pop the /None key in the SMask processing of the 'gs' in a PDF 1.4 document. Fixes SourceForge bug #459647 for Artifex customer Accusoft. (lib/pdf_draw.ps [1.35]: 2001/10/05 18:25:16 rayjj) - Enhances -dDEBUG for encrypted PDF files to print strings after decryption. (lib/pdf_sec.ps [1.5]: 2001/10/09 20:17:23 lpd) - If LastPage was greater than the number of pages in the document, a rangecheck was generated. Instead, limit LastPage (silently) to the number of pages in the document. If FirstPage is past end of document, issue a warning. Also, if no pages are processed due to FirstPage > LastPage, give a clear error message. SourceForge bug #470025. (lib/pdf_main.ps [1.35]: 2001/10/12 07:07:54 rayjj) - Changing the hack in PDF font processing, which chooses character width with encodings where the same character appears more than once. New code takes width for character code which appears in Differences. Source Forge bugs #444366, #468389. (lib/pdf_font.ps [1.22]: 2001/10/14 01:28:05 igorm) - Fix for #471414. Thanks to Leon Bottou for his excellent analysis and fix for this problem. Ghostscript was incorrectly handling a PDF shading dictionary in which the /Function entry contained an array of function dictionary references. An additonal oforce was required in the array processing loop. (lib/pdf_draw.ps [1.36]: 2001/10/16 22:20:31 dancoby) - Applied two patches reported in http://www.ghostscript.com/pipermail/gs-code-review/2001-October/001255.html by Hideyuki Suzuki / hideyuki at sat dot t dot u-tokyo dot ac dot jp. pdf_font.ps: automatic substitution & transformation of CID-keyed fonts. pdf_ops.ps: make spacings vertical when WMode is 1. (lib/pdf_font.ps [1.23], lib/pdf_ops.ps [1.17]: 2001/10/19 16:42:47 masata-y)Interpreter
Fixes problems: - Adds a -dNOCCFONTS switch to disable use of compiled-in fonts. (lib/gs_ccfnt.ps [1.5], lib/gs_init.ps [1.39]: 2001/10/01 05:25:55 lpd) - After removing a compiled font with undefinefont, loading the font or asking for its resourcestatus left extra information on the stack. Fixes SourceForge #458818. (lib/gs_res.ps [1.16]: 2001/10/01 05:56:58 lpd) - Clean up PostScript files in examples directory to prevent spurious bug reports caused when running more than a sigle file or running chess.ps without cheq.ps in the current directory. Thanks to Russell Lang for cleanup on DSC comment and structure. (examples/alphabet.ps [1.2], examples/chess.ps [1.2], examples/colorcir.ps [1.2], examples/doretree.ps [1.2], examples/escher.ps [1.2], examples/golfer.ps [1.2], examples/grayalph.ps [1.2], examples/snowflak.ps [1.2], examples/tiger.ps [1.2], examples/vasarely.ps [1.2], examples/waterfal.ps [1.3]: 2001/10/01 21:28:25 rayjj) - Remove this file which was referenced from chess.ps -- now it is included in chess.ps to prevent errors when cheq.ps could not be located. (examples/cheq.ps [1.2]: 2001/10/01 21:33:05 rayjj) - When using a substitute for an unknown font, add an alias in FontDirectory under the original requested font name. (lib/gs_fonts.ps [1.12]: 2001/10/01 21:35:53 rayjj) - Undo previous 1.12 update. The PS file that exhibited the problem was bad as was my testing against Adobe PS behaviour. Substituted fonts are neither aliased, nor entered in the FontDirectory by Adobe PostScript. Fixes regression bug with Genoa PS LL3 FTS test 313-01.ps. (lib/gs_fonts.ps [1.13]: 2001/10/09 18:01:17 rayjj) - Fixing inaccurate coding in Type 2 font processing : when GlobalSubrs absents, old code damages useful information in charstring_font_refs_s::GlobalSubrs, possibly causing indeterministic error. (zfont2.c [1.4]: 2001/10/11 17:55:32 igorm) - Fix : Making GlobalSubrs to be shared for all descendent fonts within CFF CID font. 1/2 fix for Source Forge bug #468389 "rangecheck in type2execchar" (lib/gs_cff.ps [1.10]: 2001/10/12 08:52:14 igorm) - Fixes for stdin as a result of using callouts.

Fixes problems: - Fixes nontermination of triangle subdivision in shading, as triggered by FTS 446-01.ps. The criterion for whether a triangle spans more than one pixel was too conservative, as it took the fill adjust into account. (gxshade4.c [1.6]: 2001/10/01 21:16:47 raph) - Correct inverted Decode cases of ImageType 4 color range masks for the Monochrome single bit per pixel case.

Fixes problems: - Removing the dependence of graphic library on PS interpreter. Source Forge bug #415003. (lib.mak [1.48]: 2001/04/20 09:38:39 igorm) - Undoes makefile breakage introduced in previous version (for VMS). (icclib.mak [1.3], lib.mak [1.50]: 2001/04/24 18:36:55 raph) - !ifndef COMPILED_INITS instead of !ifndef COMPILE_INITS Discovered fixing bug #414985 from anonymous user (msvclib.mak [1.13]: 2001/04/28 00:53:46 alexcher) - Optimization for shading fill. The general path filling algorithm subdivides fill region with trapezoid or rectangle subregions and then paints each subregion with given color. If the color is shading, each subregion to be subdivided into areas of constant color. But with radial shading each area is a high order polygon, being subdivided into smaller subregions, so as total number of subregions grows huge. Faster processing is done here by changing the order of subdivision cycles : we first subdivide the shading into areas of constant color, then apply the general path filling algorithm (i.e. subdivide each area into trapezoids or rectangles), using the filling path as clip mask. Source Forge bug #414022. (lib.mak [1.51]: 2001/05/10 18:36:40 igorm) - Adobe PhotoShop 5+ duotone code assumes that setcolor operator calls tint transform function if source colors don't make a subset of device colors.

(msvc32.mak [1.18], msvclib.mak [1.16], winlib.mak [1.11]: 2001/09/22 07:07:02 ghostgum) - Prevent memory corruption when reading %statementedit. Allocate lineedit buffer in correct memory space. Line being assembled is stored in a PostScript string during callouts, so prevent zfilelineedit from reading more than max_string_size bytes. Allocate extra space for trailing new-line for statementedit, rather than fiddling the string length which broke when sreadline reallocated the string. (int.mak [1.50]: 2001/09/22 07:26:45 ghostgum) - pdfwrite failed to recognize several of the standard screen spot functions: Ellipse, Round, and Diamond weren't implemented, and several of the others didn't match the PostScript implementation because of float/double discrepancies. Also, pdfwrite wrote out halftone screens using the adjusted ("actual") frequency and angle values rather than the requested values. Fixes SourceForge #446676.

Paint areas outside the page with the window background colour or light grey. Save and restore window size using registry. Add "Paste" to system menu of text window. Make error message box a child of text window to avoid it appearing behind the text window. To allow user to read the error message, the text window is not automatically destroyed in the event of an error. The user must close text window using close button or system menu. If text window closed, return e_Fatal to poll function to provide a cleaner exit without a stack dump.

Original implementation uses transfer functions to simulate the indexed color space. Currently, GS always ignore transfer functions. The replacement procedure uses indexed color space directly. This Idiom should really be in a file in the IdiomSet directory of the Resource path, but we put it here until GS has a way to handle distribution and installation of Resources.

(gscsepr.c [1.11]: 2001/04/20 10:07:48 igorm) - Optimization for shading fill. The general path filling algorithm subdivides fill region with trapezoid or rectangle subregions and then paints each subregion with given color. If the color is shading, each subregion to be subdivided into areas of constant color. But with radial shading each area is a high order polygon, being subdivided into smaller subregions, so as total number of subregions grows huge. Faster processing is done here by changing the order of subdivision cycles : we first subdivide the shading into areas of constant color, then apply the general path filling algorithm (i.e. subdivide each area into trapezoids or rectangles), using the filling path as clip mask.

Modified Files: gs/icclib/icc.c gs/src/gdevpdf.c gs/src/gp_vms.c gs/src/gsnogc.c gs/src/icclib.mak gs/src/openvms.mmk gs/src/x_.h Added Files: gs/src/vms_x_fix.h Patches for OpenVMS (icclib/icc.c [1.4], vms_x_fix.h [1.1]: 2001/04/20 09:56:22 joukj) This is the fix for [ #425014 ] Compile error on AIX in icc.c. The control87 is not defined on AIX systems (or probably on anything but x86 systems). This was suggested by Graeme Gill.

Fixes problems: - Correct the Unix executable handing of the display device formats of 8bit and 24bit per pixel RGB. (dxmain.c [1.3]: 2001/04/08 08:40:29 ghostgum) - Ghostscript should return to the caller, not exit. Remove exit() from gp_do_exit() for all platforms except VMS.

Fixes problems: - AR4 doesn't like fonts with empty FontBBox which happens when the font contains only space characters. Small BBox causes AR 4 to display a hairline. So we use the full BBox. (gdevpdfw.c [1.11]: 2001/04/08 14:12:56 alexcher)Interpreter
Fixes problems: - Ghostscript should return to the caller, not exit. Remove exit() from gp_do_exit() for all platforms except VMS. (gs.c [1.6]: 2001/04/08 08:43:24 ghostgum) - Need a cast to (gs_memory_t *) to prevent errors on some compliers. Change provided by Nelson H. F. Beebe. (zfdctd.c [1.6]: 2001/04/09 05:15:57 rayjj) - Setting an ICC color space now invalidates the joint cache, so that TransformPQR gets computed. The profile is explicitly loaded so that the TransformPQR procedures have access to the white point. Also, the photometric interpretation of the hack for /All separation color spaces is reversed. Fixes Fixed_Original.pdf from Michael Jahn and Adobe tech note 5002_EPSF_Spec.pdf. (zicc.c [1.2]: 2001/04/09 06:09:58 raph) Updates version number and date in preparation for 7.00 release.
