(cc-head.mak) - -</pre><h3><a name="V3.70p1_Drivers"></a>Drivers</h3><pre> -Fixes bugs: - - The os2prn driver smashed memory. (gdevos2p.c) - - Some initialized structures weren't declared 'static'. -(gdevpdf.c, gdevpdfm.c) - - The PNG driver wouldn't compile with some older versions of the -PNG library. (gdevpng.c) - -</pre> - -<h2><a name="Version3.70"></a>Version 3.70 (limited) (6/23/96)</h2> - -<p> -This is the candidate fileset for 4.0. Aside from one optimization -for the PDF writer, the only changes are bug fixes. - -<h3><a name="V3.70_Documentation"></a>Documentation</h3><pre> - -Renames all the documentation files from *.doc to *.txt, since the .doc -extension didn't give any information about the format of the file. -(readme, *.doc, *.txt) - -Notes that IJG JPEG library v6[a] is now required. (jpeg.mak) - -Brings ps2pdf.1 up to date. (ps2pdf.1) - -Adds a new file describing Aladdin's C coding practices. (c-style.txt) - -Updates the man pages to refer to version 4.0. (gs.1, pdf2ps.1, ps2ascii.1, -ps2pdf.1) - -</pre><h3><a name="V3.70_Procedures"></a>Procedures</h3><pre> - -Changes some file names to fit within the MS-DOS 8.3 limit. (gs.mak) - -Adds the PDF writer to the remaining 32-bit configurations (Watcom, OS/2, -MSC). (watc.mak, watcwin.mak, os2.mak, msc.mak, msvcwint.mak) - -Changes the -sFONTMAP= switch so it can take a list of font names, like a -search path. (use.txt) - -</pre><h3><a name="V3.70_Drivers"></a>Drivers</h3><pre> - -Fixes bugs: - - Signed and unsigned values were mixed inconsistently. (gdevcdj.c) - - PDF files could contain e-format floating point numbers, which the -PDF specification doesn't allow. (gdevpdfx.h, gdevpdf*.c) - - The PDF writer didn't handle glyphshow properly. (gs_pdfwr.ps) - - The PDF writer did the wrong thing with fonts whose FontMatrix had -a non-zero translation component. (gs_pdfwr.ps, gdevpdft.c) - - The stand-alone bounding box device could crash when setting -parameters. (gdevbbox.c) - - The mswinpr2 driver smashed memory. (gdevwpr2.c) - -Changes the PDF writer so that if it encounters a re-encoded character, it -tries to map it to an encoded character in the standard (ISO Latin-1) -encoding rather than converting the entire string containing it to a bitmap. -This dramatically improves output file size for files with a few divergently -encoded characters, but it may cause the text in the PDF file to differ from -the text in the PostScript input. (gdevpdft.c) - -Disallows BitsPerPixel=16 in the MS Windows and OS/2 drivers, since this bit -depth is not supported by Windows and would require special extra buffering. -(install.txt, dwtext.h, dwtext.cpp, gdevmswn.c, gdevpm.c, gdevwpr2.c) - -</pre><h3><a name="V3.70_Platforms"></a>Platforms</h3><pre> - -Fixes bugs: - - On the PC platforms, file names weren't changed to reflect the -value of CONFIG. (gs.mak, bc*.mak, ms*.mak, os2.mak, tc*.mak, watc*.mak, -wccommon.mak) - -Modifies some makefiles for greater reusability. (bclib.mak, watclib.mak) - -</pre><h3><a name="V3.70_Fonts"></a>Fonts</h3><pre> - -Changes the font searching rules in the following NON-BACKWARD-COMPATIBLE -way: (gs_fonts.ps, gs_res.ps) - - -sFONTMAP=files specifies a list of files containing fontmaps; -previously, it specified only a single fontmap file. - - If -sFONTMAP= is not used, the interpreter reads the Fontmaps from -*all* directories on the search path, and does so even if FONTPATH or -GS_FONTPATH is set; previously, it read only the first Fontmap, and only if -[GS_]FONTPATH was not set. - - Fontmap(s) take precedence over [GS_]FONTPATH; previously, -[GS_]FONTPATH caused Fontmap to be ignored. (You can still force Fontmap to -be ignored with -dNOFONTMAP.) - - Earlier [GS_]FONTPATH entries take precedence over later; -previously, later entries took precedence over earlier. Note that this is -different from Fontmap: earlier Fontmaps in the search path take precedence -over later, but within a single Fontmap, later entries take precedence over -earlier (for backward compatibility). - - [GS_]FONTPATH is consulted only if there is no Fontmap entry for a -font, or no Fontmap entry leads to successful loading; previously, -[GS_]FONTPATH was always consulted at startup. - - If loading a font fails, the interpreter tries the next Fontmap -entry; previously, it fell back to font substitution. - -</pre><h3><a name="V3.70_Interpreter"></a>Interpreter</h3><pre> - -Fixes bugs: - - Filters didn't peek ahead for an EOD (see Streams below). -(zfileio.c, zpaint.c) - -Splits up a file to allow internal access to user and system parameters even -in Level 1. (zmisc2.c, zusparam.c) - -Adds LIBPATH as a predefined name in systemdict. Its value is an array of -strings comprising the library search path. (imain.c) - -</pre><h3><a name="V3.70_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre> - -Fixes bugs: - - A Dests dictionary entry with an array (rather than a dictionary) -value caused an error. (pdf_main.ps) - - Rotated pages could have incorrect translation and/or clipping. -(pdf_main.ps) - -</pre><h3><a name="V3.70_Streams"></a>Streams</h3><pre> - -Fixes bugs: - - If a buffer boundary fell just before an EOD, and the client read -exactly as much data as was present before the EOD, filters didn't consume -the EOD. (This is required as a tricky consequence of the Adobe -specification.) (stream.h, strimpl.h, stream.c) - -</pre><h3><a name="V3.70_Library"></a>Library</h3><pre> - -Fixes bugs: - - An extra column of bits could get turned on at the right edge of -masked or monochrome images. (gximage2.c) - - Rasterizing very long curves could cause arithmetic errors or -floating point overflows. (gxpcopy.c) - - Banding with large line widths could truncate curves or introduce -spurious lines. (gxclpath.c) - -</pre> - -<hr> - -<h2><a name="Version3.69"></a>Version 3.69 (limited) (6/14/96)</h2> - -<p> -More bug fixes, plus one irresistible new feature: the ability to use -TrueType fonts as freely as Type 1 fonts. Also, one new feature (outside -clipping) that was needed for Aladdin's PCL XL project. We incremented the -version number because of the change in trapezoid and path filling (see -under Library below). - -<h3><a name="V3.69_Documentation"></a>Documentation</h3><pre> -Brings documentation about fonts up to date. (fonts.doc) - -Updates current.doc to reflect changes since 3.53. (current.doc) - -Updates the DLL documentation to reflect recent changes.

(new-user.doc) - -Updates the OS/2 documentation to make it current. (install.doc, make.doc) - -Documents -dCOLORSCREEN=0. (use.doc) - -</pre><h3><a name="V3.69_Procedures"></a>Procedures</h3><pre> - -Fixes bugs: - - 'make clean' didn't work in the Watcom environment. -(wmakebat.bat, gs.mak, msc.mak, msvcwint.mak, os2.mak, tccommon.mak, -unixhead.mak, wccommon.mak) - - The X11 libraries were listed in an incorrect order. -(ansihead.mak, cc-head.mak, gcc-head.mak, ugcclib.mak, unix-end.mak) - - The OS/2 makefile didn't ignore errors from `erase' commands. -(os2.mak) - -Adds the PDF writer to the 32-bit MS Windows configuration. (bcwin32.mak) - -Adds the PNG drivers to the 32-bit MS Windows platform, since they now -compile properly. (bcwin32.mak) - -Changes the ttfont feature so that it refers to support for direct usage of -TrueType fonts; puts support for Type 42 fonts into a separate feature -(type42). (gs.mak, int.mak) - -Adds direct TrueType font support to the Windows platforms. (bcwin.mak, -bcwin32.mak) - -Rewrites vms.mak to be structured more like the other makefiles. (vms.mak, -modules.lis) - -Makes the device lists in vms-*.mak the same as those for the Unix -configurations. (vms-cc.mak, vms-decc.mak, vms-gcc.mak) - -Changes the default X library directory for gcc to /usr/X11/lib. -(gcc-head.mak) - -Adds the list of devices to --help, since HylaFax depends on this. -(imainarg.c) - -Adds -dCOLORSCREEN=0 to indicate use of 4 separate color screens with the -same frequency and angle. (gs_init.ps) - -</pre><h3><a name="V3.69_Utilities"></a>Utilities</h3><pre> - -Fixes bugs: - - When ps2epsi encountered a blank page, it called the -(undocumented) .quit operator with only one argument, causing a stack -underflow. (ps2epsi.ps) - - An extraneous file was included in the fileset. (checkacc.ps) - - A file was omitted from the fileset. (bench.c) - - Images in PostScript files produced by pdf2ps were processed about -50 times slower than they should have been. (gs_pdf.ps) - -</pre><h3><a name="V3.69_Drivers"></a>Drivers</h3><pre> - -Fixes bugs: - - An #include was omitted. (gdevpdfi.c) - - The BJC driver could get into an inconsistent state. (gdevcdj.c) - - Braces were omitted around the values for two initialized byte -arrays. (gdevpcx.c) - - A function used 'float' in its argument list, causing problems in -mixed ANSI/non-ANSI compilation. (gdevcdj.c) - - signed and unsigned char pointers were used inconsistently. -(gdevcdj.c, gdevcgml.c) - - Some header files weren't protected against double inclusion. -(gdevprn.h, gdevtifs.h) - - The 24-bit PNG driver included unnecessary copies of the color -mapping procedures.

(gdevpdfi.c) - - The PDF writer produced zero-width, zero-height images for -non-standard fonts. (bug introduced since 3.68) (gdevpdfi.c) - - The PDF writer got confused if the input file invoked -setpagedevice. (gdevpdfp.c) - - The PDF writer put annotations on the page after the one they were -supposed to be on. (gdevpdf.c) - - The PDF writer sometimes failed to set the font when needed. -(gdevpdf.c) - - The PDF writer could produce in-line images that were too large. -(gdevpdfi.c) - - The PDF writer didn't scale explicit character and word spacing -(ashow/widthshow/awidthshow) properly. (gdevpdft.c) - - The PDF writer didn't copy named destination or article title -strings, possibly leading to dangling pointers. (gdevpdf.c, gdevpdfm.c) - - The PDF writer produced incorrect output for re-encoded fonts. -(It now converts any string containing characters in non-standard positions -to bitmaps; this will be fixed in a later release.) (gs_pdfwr.ps, -gdevpdfx.h, gdevpdfp.c, gdevpdft.c) - -Updates a few drivers for the change in the handling of band device -procedures. (gdevcp50.c, gdevdjet.c) - -Updates the X Windows driver for strip halftones. (gdevx.c) - -Adds anti-aliasing capability to the os2pm device.

(dwmain.cpp) - - An identifier exceeded VAX VMS C's limit of 31 characters. -(gscspace.h) - - File name enumeration didn't work properly on Unix systems -(still/again). (gp_unifs.c) - - On MS Windows, If you closed Ghostscript with the system menu, you -only closed the text window; Ghostscript kept running and you had to use the -task manager to kill it. (dwmain.cpp, dwmainc.cpp, dwtext.cpp) - - Some DLL-related typedefs were not consistent. (dwdll.h, gsdll.h, -dpmainc.c, dwdll.cpp) - - Attempts to call the DLL before it was initialized were not -detected. (gsdll.c) - - Bitmap line lengths were rounded up even on 32-bit Windows, which -doesn't want this. (gdevwdib.c) - -Further improves the handling of attempts to use the DLL when it is already -in use. (dwdll.cpp, gsdll.c) - -Adds a DLL-compatible main program for OS/2. (dpmainc.c, gp_os2.c, gsdll.c) - -</pre><h3><a name="V3.69_Fonts"></a>Fonts</h3><pre> - -Fixes bugs: - - The WingDings TrueType font wasn't loaded properly. (gs_ttf.ps) - -Makes changes so that TrueType fonts can appear in the Fontmap and can be -loaded directly. (gs_fonts.ps, gs_ttf.ps) - -</pre><h3><a name="V3.69_Interpreter"></a>Interpreter</h3><pre> - -Fixes bugs: - - Executing a .quit with only 1 element on the operand stack caused -an invalid access. (zcontrol.c) - - The usage help message contained incorrect double %%s. -(imainarg.c) - - If an initialization file tried to use any Encodings other than -the 4 registered ones, it couldn't find them. (gs_init.ps, gs_res.ps) - - Places that expected arrays of coordinates (rectangles, -x/y/xyshow) didn't accept packed arrays. (ibnum.c, zdps1.c) - - filterdict was still visible after initialization. (gs_init.ps) - - The usage error message wasn't terminated by a newline. -(imainarg.c) - - setcacheparams (or setting the MaxFontCache user parameter) didn't -actually affect the size of the character cache. (zfont.c, zmisc2.c) - - The main interpreter loop declared iref as a ref *, even though it -may only be a ref_packed *. (iref.h, interp.c) - -Changes the character cache so it ignores absurd FontBBox values. Nothing -in the Adobe spec suggests doing this, but it is necessary for handling -questionable output produced by PageMaker 5.0 (an Adobe product!). -(zchar1.c) - -Changes some type declarations slightly to reduce the number of 'discarding -const' compiler warnings. (igc.h, igc.c, igcref.c) - -Adds .setclipoutside and .currentclipoutside operators for accessing the new -outside clipping capability.

(gschar.c, gxcpath.c, gxfill.c) - - TrueType or Type 42 glyphs with a repeat count that crossed a -contour boundary produced incorrect output. (gstype42.c) - - TrueType / Type 42 composite glyphs involving rotation were placed -incorrectly. (gstype42.c) - - Type 42 fonts with an absent or incorrect FontBBox could fail to -produce output. (gstype42.c) - - Some header files weren't protected against double inclusion. -(gsio.h, gdebug.h) - - Decoding filters didn't "look ahead" to detect EOD, so if the last -read operation before closing the filter ended just before the EOD mark, the -EOD mark might not be absorbed. (stream.h, stream.c) - - Filling paths consisting of multiple subpaths that overlap in Y -produced slightly inaccurate output. We were unable to find a way to fix -this without making a NON-BACKWARD-COMPATIBLE change in the interface for -the recently introduced fill_trapezoid device procedure. (gxdevice.h, -gdevbbox.c, gdevddrw.c, gdevnfwd.c, gxfill.c) - - When banding, get_bits didn't detect calls with out-of-range Y -values.

(gdevbbox.c) - - The bounding box device got confused by files that filled the -entire page with a background color. (gdevbbox.c) - - The bounding box device produced infinite-height boxes for certain -kinds of data. (gdevbbox.c) - -Changes some type declarations slightly to reduce the number of 'discarding -const' compiler warnings.

(New bug in 2.9.x.) - - setpattern didn't set the current color space correctly if the -current color space wasn't a Pattern space. - - If the current color space was an uncolored Pattern space but the -current color was a colored Pattern, currentcolor returned extra values on -the operands stack. - - .buildfont1 in gs_type1.ps didn't force binding of the old -definition, causing ps2ascii to loop endlessly. - -Adds a facility for writing and reading dictionaries in binary object -sequences. This is experimental and subject to change in the future. - -</pre><h3><a name="V3.0_Streams"></a>Streams</h3><pre> - -Fixes bugs: - - gs_run_string and ccinit didn't have any way to mark the string -as "foreign", which confused the GC. - -</pre><h3><a name="V3.0_Library"></a>Library</h3><pre> - -Fixes bugs: - - gxchar.h had an extra comma after the last element of the -show_width_status enum, which upset some compilers. - - stroke and strokepath didn't correctly skip zero-length segments -if the line width was less than one pixel, or if there was a closed subpath -consisting entirely of zero-length segments. - - strokepath sometimes incorrectly added a moveto at the end of the -path. -</pre> - -<!-- [3.0 begin visible trailer] =========================================== --> -<hr> - -<p> -<small>Copyright © 1996, 1997, 1998 Aladdin Enterprises. -All rights reserved.</small> - -<p> -This software is provided AS-IS with no warranty, either express or -implied. - -This software is distributed under license and may not be copied, -modified or distributed except as expressly authorized under the terms -of the license contained in the file LICENSE in this distribution. - -<p> -<small>Ghostscript version 7.07, 17 May 2003 - - -<!-- [3.0 end visible trailer] ============================================= --> - -</body> -</html> |
