Aside from one optimization 692for the PDF writer, the only changes are bug fixes. 693 694<h3><a name="V3.70_Documentation"></a>Documentation</h3><pre> 695 696Renames all the documentation files from *.doc to *.txt, since the .doc 697extension didn't give any information about the format of the file. 698(readme, *.doc, *.txt) 699 700Notes that IJG JPEG library v6[a] is now required. (jpeg.mak) 701 702Brings ps2pdf.1 up to date. (ps2pdf.1) 703 704Adds a new file describing Aladdin's C coding practices. (c-style.txt) 705 706Updates the man pages to refer to version 4.0. (gs.1, pdf2ps.1, ps2ascii.1, 707ps2pdf.1) 708 709</pre><h3><a name="V3.70_Procedures"></a>Procedures</h3><pre> 710 711Changes some file names to fit within the MS-DOS 8.3 limit. (gs.mak) 712 713Adds the PDF writer to the remaining 32-bit configurations (Watcom, OS/2, 714MSC). (watc.mak, watcwin.mak, os2.mak, msc.mak, msvcwint.mak) 715 716Changes the -sFONTMAP= switch so it can take a list of font names, like a 717search path. (use.txt) 718 719</pre><h3><a name="V3.70_Drivers"></a>Drivers</h3><pre> 720 721Fixes bugs: 722 - Signed and unsigned values were mixed inconsistently. (gdevcdj.c) 723 - PDF files could contain e-format floating point numbers, which the 724PDF specification doesn't allow. (gdevpdfx.h, gdevpdf*.c) 725 - The PDF writer didn't handle glyphshow properly. (gs_pdfwr.ps) 726 - The PDF writer did the wrong thing with fonts whose FontMatrix had 727a non-zero translation component. (gs_pdfwr.ps, gdevpdft.c) 728 - The stand-alone bounding box device could crash when setting 729parameters. (gdevbbox.c) 730 - The mswinpr2 driver smashed memory. (gdevwpr2.c) 731 732Changes the PDF writer so that if it encounters a re-encoded character, it 733tries to map it to an encoded character in the standard (ISO Latin-1) 734encoding rather than converting the entire string containing it to a bitmap. 735This dramatically improves output file size for files with a few divergently 736encoded characters, but it may cause the text in the PDF file to differ from 737the text in the PostScript input. (gdevpdft.c) 738 739Disallows BitsPerPixel=16 in the MS Windows and OS/2 drivers, since this bit 740depth is not supported by Windows and would require special extra buffering. 741(install.txt, dwtext.h, dwtext.cpp, gdevmswn.c, gdevpm.c, gdevwpr2.c) 742 743</pre><h3><a name="V3.70_Platforms"></a>Platforms</h3><pre> 744 745Fixes bugs: 746 - On the PC platforms, file names weren't changed to reflect the 747value of CONFIG. (gs.mak, bc*.mak, ms*.mak, os2.mak, tc*.mak, watc*.mak, 748wccommon.mak) 749 750Modifies some makefiles for greater reusability. (bclib.mak, watclib.mak) 751 752</pre><h3><a name="V3.70_Fonts"></a>Fonts</h3><pre> 753 754Changes the font searching rules in the following NON-BACKWARD-COMPATIBLE 755way: (gs_fonts.ps, gs_res.ps) 756 - -sFONTMAP=files specifies a list of files containing fontmaps; 757previously, it specified only a single fontmap file. 758 - If -sFONTMAP= is not used, the interpreter reads the Fontmaps from 759*all* directories on the search path, and does so even if FONTPATH or 760GS_FONTPATH is set; previously, it read only the first Fontmap, and only if 761[GS_]FONTPATH was not set. 762 - Fontmap(s) take precedence over [GS_]FONTPATH; previously, 763[GS_]FONTPATH caused Fontmap to be ignored. (You can still force Fontmap to 764be ignored with -dNOFONTMAP.) 765 - Earlier [GS_]FONTPATH entries take precedence over later; 766previously, later entries took precedence over earlier. Note that this is 767different from Fontmap: earlier Fontmaps in the search path take precedence 768over later, but within a single Fontmap, later entries take precedence over 769earlier (for backward compatibility). 770 - [GS_]FONTPATH is consulted only if there is no Fontmap entry for a 771font, or no Fontmap entry leads to successful loading; previously, 772[GS_]FONTPATH was always consulted at startup. 773 - If loading a font fails, the interpreter tries the next Fontmap 774entry; previously, it fell back to font substitution. 775 776</pre><h3><a name="V3.70_Interpreter"></a>Interpreter</h3><pre> 777 778Fixes bugs: 779 - Filters didn't peek ahead for an EOD (see Streams below). 780(zfileio.c, zpaint.c) 781 782Splits up a file to allow internal access to user and system parameters even 783in Level 1. (zmisc2.c, zusparam.c) 784 785Adds LIBPATH as a predefined name in systemdict. Its value is an array of 786strings comprising the library search path. (imain.c) 787 788</pre><h3><a name="V3.70_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre> 789 790Fixes bugs: 791 - A Dests dictionary entry with an array (rather than a dictionary) 792value caused an error. (pdf_main.ps) 793 - Rotated pages could have incorrect translation and/or clipping. 794(pdf_main.ps) 795 796</pre><h3><a name="V3.70_Streams"></a>Streams</h3><pre> 797 798Fixes bugs: 799 - If a buffer boundary fell just before an EOD, and the client read 800exactly as much data as was present before the EOD, filters didn't consume 801the EOD. (This is required as a tricky consequence of the Adobe 802specification.) (stream.h, strimpl.h, stream.c) 803 804</pre><h3><a name="V3.70_Library"></a>Library</h3><pre> 805 806Fixes bugs: 807 - An extra column of bits could get turned on at the right edge of 808masked or monochrome images. (gximage2.c) 809 - Rasterizing very long curves could cause arithmetic errors or 810floating point overflows. (gxpcopy.c) 811 - Banding with large line widths could truncate curves or introduce 812spurious lines. (gxclpath.c) 813 814</pre> 815 816<hr> 817 818<h2><a name="Version3.69"></a>Version 3.69 (limited) (6/14/96)</h2> 819 820<p> 821More bug fixes, plus one irresistible new feature: the ability to use 822TrueType fonts as freely as Type 1 fonts. Also, one new feature (outside 823clipping) that was needed for Aladdin's PCL XL project. We incremented the 824version number because of the change in trapezoid and path filling (see 825under Library below). 826 827<h3><a name="V3.69_Documentation"></a>Documentation</h3><pre> 828Brings documentation about fonts up to date. (fonts.doc) 829 830Updates current.doc to reflect changes since 3.53. (current.doc) 831 832Updates the DLL documentation to reflect recent changes. (dll.doc) 833 834Documents a workaround for the code generation bug in gcc 2.7.x. (make.doc) 835 836Changes the contact information for potential commercial customers in 837Europe. (new-user.doc) 838 839Updates the OS/2 documentation to make it current. (install.doc, make.doc) 840 841Documents -dCOLORSCREEN=0. (use.doc) 842 843</pre><h3><a name="V3.69_Procedures"></a>Procedures</h3><pre> 844 845Fixes bugs: 846 - 'make clean' didn't work in the Watcom environment. 847(wmakebat.bat, gs.mak, msc.mak, msvcwint.mak, os2.mak, tccommon.mak, 848unixhead.mak, wccommon.mak) 849 - The X11 libraries were listed in an incorrect order. 850(ansihead.mak, cc-head.mak, gcc-head.mak, ugcclib.mak, unix-end.mak) 851 - The OS/2 makefile didn't ignore errors from `erase' commands. 852(os2.mak) 853 854Adds the PDF writer to the 32-bit MS Windows configuration. (bcwin32.mak) 855 856Adds the PNG drivers to the 32-bit MS Windows platform, since they now 857compile properly. (bcwin32.mak) 858 859Changes the ttfont feature so that it refers to support for direct usage of 860TrueType fonts; puts support for Type 42 fonts into a separate feature 861(type42). (gs.mak, int.mak) 862 863Adds direct TrueType font support to the Windows platforms. (bcwin.mak, 864bcwin32.mak) 865 866Rewrites vms.mak to be structured more like the other makefiles.

(gsimage*.c, gximage*.c) 1537 1538Fully implements the high-level bitmap image calls in the driver API. This 1539includes some driver API changes; however, this part of the API was clearly 1540documented as not stable enough to rely on.

(gxfixed.h, gscoord.c, gsmisc.c) 1555 1556Makes one further NON-BACKWARD-COMPATIBLE change in the existing 1557higher-level driver procedures (fill_path, stroke_path, fill_mask): we make 1558the imager state pointer an explicit argument, rather than a member of the 1559gx_fill/stroke_params structure. We now consider the specification of these 1560procedures stable, and have removed the "subject to change" notice from the 1561documentation. (gxdevice.h, gxpaint.h, gdevbbox.c, gdevnfwd.c, gxacpath.c, 1562gxclpath.c, gxclread.c, gxfill.c, gxpaint.c, gxstroke.c) 1563 1564Extends halftone bitmaps to include "strip" and "shift" information, 1565allowing halftone cells with arbitrary angles to be stored in space 1566proportional to the number of bits in the cell rather than the square of the 1567number of bits. This requires adding new (optional) strip_tile_rectangle 1568and strip_copy_rop driver procedures that are like tile_rectangle and 1569copy_rop respectively but accept a strip bitmap rather than an ordinary 1570tile; these procedures supersede tile_rectangle and copy_rop (although these 1571also remain, defined in terms of the new ones).

NOTE: this is not actually implemented 1582yet. (gslparam.h) 1583 1584Changes the initialization code so that it passes the system allocator as an 1585argument to module initialization procedures. While this is theoretically a 1586NON-BACKWARD-COMPATIBLE change, module initialization procedures are not 1587documented and presumably are not used by any code outside the 1588implementation. (gscdefs.h, gconf.c, gdevmrop.c, gsinit.c, gxclimag.c, 1589gxclpath.c) 1590 1591Splits up gs_lib_init into two procedures, allowing specification of a 1592different default allocator for the library.

(gdevpcx.c) 2040 - The svga16 driver initialized its procedures incorrectly. 2041(gdevpcfb.c) 2042 2043Adds text writing capability to the PDF writer.

(gdevpdfx.h, gdevpdf.c, gdevpdfp.c, gdevpdft.c) 2046 2047Adds garbage collection and finalization for device instances (gscdefs.h, 2048gsdevice.h, gxdevice.h, gconf.c, gdevmrop.c, gsdevice.c, gslib.c, gsmain.c). 2049(See the "Driver instance allocation" section of drivers.doc for more 2050details about what is required to make this work.) 2051 2052 - When an open device is freed (explicitly, by garbage collection, 2053or by 'restore'), if the device was allocated dynamically by Ghostscript's 2054standard allocator, the device's close procedure will be called. THIS IS A 2055NON-BACKWARD-COMPATIBLE CHANGE for dynamically created devices, which 2056formerly were not closed automatically, even when Ghostscript exited. 2057 2058 - Device instances allocated in GC-able space will be traced 2059like other objects, assuming they have proper structure descriptors. 2060 2061Provides a (very slow but correct) default implementation of copy_alpha. 2062(gxcindex.h, gdevdflt.c, gsimage4.c) 2063 2064Removes the implementation of copy_alpha in gdevpbm.c, since this is now 2065implemented (more efficiently) in gdevm24.c. (gdevpbm.c) 2066 2067Adds TextAlphaBits and GraphicsAlphaBits as readable parameters for all 2068devices.

(idict.c, iinit.c) 2090 - The if and ifelse operators didn't check that their 2091'procedure' arguments were actually procedures. (interp.c, zcontrol.c) 2092 - The undef operator was defined even in Level 1 2093configurations. (We need this capability for all configurations, so 2094we always define .undef.) (zdict.c, gs_*.ps, pdf_*.ps) 2095 - In Level 1 configurations, copying a dictionary should copy the 2096access attributes, but it didn't. We have to work around this 2097compatibility quirk in a lot of places. (gs_cidfn.ps, gs_cmap.ps, 2098gs_dps1.ps, gs_fonts.ps, gs_init.ps, gs_l2img.ps, gs_lev2.ps, gs_pdf.ps, 2099gs_pfile.ps, gs_res.ps, gs_setpd.ps, gs_type1.ps, zdict.c) 2100 - DSC comments that crossed a buffer boundary didn't call the 2101scan_dsc_proc. (iscan.c) 2102 - "statusdict /setpage get exec" caused an error. (gs_statd.ps) 2103 - The default size of systemdict had become slightly too small. 2104(iinit.c) 2105 - Doing a showpage or copypage would cause the equivalent of a 2106setpagedevice at the next restore or grestore. We aren't entirely sure that 2107the fix we made doesn't have bad side-effects. (gs_setpd.ps) 2108 - Not all filters accepted (and ignored) an optional dictionary 2109parameter on the stack. (ifilter.h, zfbcp.c, zfdecode.c, zfilter.c, 2110zfilterx.c, zfzlib.c, zmisc1.c) 2111 - The PixelDifference filters required a Columns parameter, rather 2112than defaulting it to 1. (spdiffx.h, zfdecode.c) 2113 - Contrary to the NEWS entry for release 3.60, the LZW filters did 2114not implement pixel differencing. (zfdecode.c, zfilter2.c) 2115 - readstring with a 0-length string didn't signal a rangecheck. 2116This doesn't make a lot of sense to me, but it's what the Adobe 2117documentation specifies. Unfortunately, we have to work around this in a 2118number of places that assumed the sensible definition (return () true 2119without reading anything). (gs_l2img.ps, pdf_font.ps, zfileio.c) 2120 - Encoded number strings didn't work (bug introduced in 3.64). 2121(ibnum.c) 2122 - The allocator could produce spurious "free large 0x...... chunk 2123not found" messages. (These didn't cause any harm, but they were 2124disturbing.) (gsalloc.c) 2125 2126Changes the default transfer function for high-resolution devices so 2127that it is the identity function if the device is continuous-tone. 2128(gs_init.ps) 2129 2130Undoes the "subversion" of zgetdevice noted in release 3.61, since it 2131is now possible to copy devices safely. (zdevice.c) 2132 2133Changes the implementation of the garbage collector and restore so that 2134object finalization code may safely free objects. (igc.c, isave.c) 2135 2136Reimplements essentially all of Type 1 BuildChar in C. (gs_init.ps, 2137gs_type0.ps (deleted), gs_type1.ps, ifont.h, zchar.c, zchar1.c, zfont.c) 2138 2139Reimplements DISKFONTS as a separate feature (diskfont.dev), and changes it 2140to use Type 4 fonts rather than special machinery. Currently this feature 2141is included only in the makefiles for 16-bit architectures. (bc.mak, 2142bcwin.mak, int.mak, tc.mak, gs_diskf.ps, gs_fonts.ps, gs_type1.ps) 2143 2144Converts the library search path from a list of strings to a (PostScript) 2145array of strings, one string per directory. (iminst.h, main.h, gs.c, 2146gsmain.c, zfile.c) 2147 2148Adds a hook procedure scan_comment_proc for processing all comments, 2149similar to scan_dsc_proc. If both are set, scan_comment_proc is used only 2150for non-DSC comments.

(pdf_main.ps) 2157 - Color space setting didn't work. (gs_pdf.ps) 2158 - The algorithm for skipping a possible blank line following the 2159'stream' keyword wasn't robust enough. (We aren't sure the new algorithm is 2160exactly right, either.) (pdf_base.ps) 2161 2162Gets rid of the special handling of the LZW decoding filter, since the 2163filter itself now handles the Predictor facility.

(spdiff.c) 2174 - Temporary write streams could cause an infinite loop. (We only 2175need such streams for the Predictor = 2 case of LZWEncode: this is why the 2176bug never showed up before.) (stream.c) 2177 2178Adds an optional reinitialization procedure to the stream template. Note 2179that this is not the same as the PostScript 'reset' operation or the stream 2180resetting operation invoked by sreset: the reinit procedure in the template 2181reinitializes any internal state of the encoder or decoder without affecting 2182buffered data.

(gscdefs.h, gxiodev.h, gconf.c, gsdevice.c, gslib.c, 2202gsinit.c, gsiodev.c) 2203 - charpath and show produced different output. We fixed this by 2204undoing a "bug fix", introduced in version 2.9, which suppressed hinting and 2205coordinate rounding for charpath; we aren't sure this won't cause some 2206obscure problems to reappear. (gstype1.c) 2207 - Clipping with a rectangle usually created a 3-rectangle clipping 2208list, slowing down all drawing operations (performance bug only). 2209(gxacpath.c) 2210 - stroking in a rotated coordinate system sometimes thought lines 2211were always thin when they actually weren't. (gxstroke.c) 2212 - An unsigned quantity wasn't properly converted to signed, possibly 2213causing band path coordinates to get mangled. (gxclread.c) 2214 - A bug in the Borland compiler caused an unsigned quantity to be 2215interpreted as signed, causing band path coordinates to get mangled. 2216(gxclread.c) 2217 2218Changes structure type pointers on 16-bit segmented systems to full 221932-bit pointers.

(pdf_font.ps) 2810 - If a character appeared twice in an encoding and the font 2811specified different Widths values for the two occurrences, the last Width 2812would be used. We patched this to ignore zero Widths, which is not the 2813correct solution but which almost always produces correct output. 2814(pdf_font.ps) 2815 - Arrays containing nulls didn't print out correctly (bug introduced 2816in 3.60). (gs_init.ps) 2817 - Some PDF files contain very large dictionaries, which caused a 2818stackoverflow.

Doing this required NON-BACKWARD-COMPATIBLE changes to the 3195interfaces of a few internal procedures: 3196 gx_check_tile_size, gx_render_device_{color,gray} 3197(gxdcolor.h, gxdht.h, gzht.h, gsht.c, gsimage1.c, gsmisc.c, gspcolor.c, 3198gsstate.c, gxcht.c, gxclbits.c, gxdither.c, gxht.c) 3199 3200Implements passing clipping information in the band list. (gzcpath.h, 3201gxacpath.c, gxclpath.c, gxclread.c, gxcpath.c) 3202 3203Removes the gs_state * parameter from the device color fill_rectangle 3204procedures and many of their callers, since it is no longer needed. This is 3205a non-backward-compatible change to an internal API. (gdevmrop.h, 3206gxdcolor.h, gxdraw.h, gxpaint.h, gdevmrop.c, gsimage.c, gspcolor.c, gxcht.c, 3207gxclread.c, gxdraw.c, gxfill.c, gxht.c, gxpaint.c, gxstroke.c) 3208 3209Removes gxdevice.h from gzstate.h, since not all modules requiring access to 3210the graphics state need to know the implementation of devices. This entails 3211adding gxdevice.h to the include lists for some modules. (gxchar.h, 3212gxcpath.h, gxcvalue.h, gxdevice.h, gxtype1.h, gzstate.h; gschar.c, 3213gscoord.c, gsdevice.c, gsimage1.c, gsimage2.c, gsimage3.c, gspaint.c, 3214gspath.c, gsstate.c, gstype1.c, gxccache.c, gxccman.c, gxhint1.c, gxhint2.c, 3215gxhint3.c, gxpaint.c) 3216 3217Adds a compile-time option, ALPHA_LSB_FIRST, which causes alpha-sampled 3218characters to be nibble-reversed in the cache. This was created for a 3219specialized application and does not interact well with the rest of the 3220code. (gsbitops.c) 3221 3222Substantially reduces the space required to represent 24- or 32-bit colors 3223in the band list, by using more aggressive color differencing. (gxcldev.h, 3224gxclist.c, gxclread.c) 3225 3226Changes the allocation of unique IDs for halftone tiles to use the gray 3227level rather than the number of 1-bits as the increment to a base ID; this 3228allows more efficient (delta) representation of halftone indices in the band 3229list. (gxcldev.h, gxclist.c, gxclread.c, gxht.c) 3230 3231Substantially speeds up entering anti-aliased characters in the cache, by 3232removing white space before compressing rather than vice versa. 3233(gsbitops.c, gxccman.c) 3234 3235</pre> 3236 3237<hr> 3238 3239<h2><a name="Version3.53"></a>Version 3.53 (1/10/96)</h2> 3240 3241<p> 3242This is an anomalous, out-of-sequence release requested by a commercial 3243licensee. It consists of 3.52 plus the following retrofits from 3.60 3244through 3.63: 3245 - PDF interpreter and pdf2ps; 3246 - Type 1 rasterizer fixes; 3247 - Type 1 rasterizer and polygon fill performance improvements; 3248 - MS Windows and OS/2 fixes; 3249 - A few other important fixes. 3250It does NOT fix all problems reported since 3.52. 3251 3252<p> 3253The list of changes below indicates which subsequent release was the source 3254of each change.

(geninit.c) 3282 [3.60] ccfontab.c was omitted from the fileset. The easiest way to 3283fix this was to rename it to icfontab.c. (gs.mak, int.mak, ccfontab.c) 3284 [3.60] The definition of pdfread.dev did an ADDMOD, not a SETMOD. 3285(int.mak) 3286 3287[3.60] Adds a -dNOFONTPATH switch to suppress any consultation of the 3288FONTPATH variable or the GS_FONTPATH environment variable. (gs_fonts.ps, 3289gs_init.ps) 3290 3291</pre><h3><a name="V3.53_Utilities"></a>Utilities</h3><pre> 3292 3293Fixes bugs: 3294 [3.61] pdf2ps didn't write Widths or Encoding in the converted file, 3295producing incorrect spacing and incorrect characters. (pdf_2ps.ps) 3296 [3.60] ps2ascii left a value on the stack for each unrecognized 3297character it processed, eventually causing a stackoverflow. (ps2ascii.ps) 3298 3299[3.61] Changes the rollconv.ps utility to produce files whose names conform 3300to the 8.3 length restriction, and to reduce the fixed RAM overhead for 3301Kanji fonts. (rollconv.ps) 3302 3303[3.60] Adds a utility for converting files produced by Macromedia's Rollup 3304program to a Type 0 form directly usable by Ghostscript. (rollconv.ps) 3305 3306</pre><h3><a name="V3.53_Drivers"></a>Drivers</h3><pre> 3307 3308Fixes bugs: 3309 [3.60] Because of a typo, the LaserJet drivers had incorrect 3310margins. This was probably a new bug in 3.5x. (gdevdjet.c) 3311 [3.60] A private name was duplicated. (gdevtfax.c) 3312 [3.60] The x11alpha driver passed invalid colors to the X library. 3313(gdevxalt.c) 3314 [3.60] The x11alpha driver set the blue component of colors 3315incorrectly. (gdevxalt.c) 3316 3317</pre><h3><a name="V3.53_Platforms"></a>Platforms</h3><pre> 3318 3319Fixes bugs: 3320 [3.63] The test for WinExec failure on Win32 was incorrect. 3321(gp_mswin.c) 3322 [3.63] getenv was declared redundantly on OS/2. (gp_os2.c) 3323 [3.63] gs16spl.c was missing <string.h>. (gs16spl.c) 3324 [3.61] Printing didn't work in 32-bit MS Windows environments. 3325(bcwin32.mak, gdevmswn.c, gp_mswin.c) 3326 [3.61] There were some compatibility problems with IBM C. (os2.mak, 3327gsdll.h, gdevpm.c, gp_os2.c) 3328 [3.60] The printjob created by Ghostscript was called "Ghostscirpt" 3329instead of "Ghostscript". (gp_os2.c) 3330 [3.60] An "export" declaration was omitted from DllInit. 3331(gp_mswin.c) 3332 3333[3.61] Adds a conditional to work around a bug in gcc 2.7.x (it didn't 3334recognize that the target of a const T * might still be mutable through 3335aliasing). (stdpre.h) 3336 3337</pre><h3><a name="V3.53_Fonts"></a>Fonts</h3><pre> 3338 3339Fixes bugs: 3340 [3.61] Rasterizing a character in a Type 1 font with an invalid 3341FontBBox left some garbage on the operand stack (bug introduced in 3.52 or 33423.60). (gs_type1.ps) 3343 [3.61] The font substitution algorithm could fail or loop. 3344(gs_fonts.ps) 3345 3346[3.60] Adds Heavy as a synonym for Bold when doing intelligent font 3347substitution. (gs_fonts.ps) 3348 3349</pre><h3><a name="V3.53_Interpreter"></a>Interpreter</h3><pre> 3350 3351Fixes bugs: 3352 [3.63] Invoking setpagedevice with an undefined key, even with 3353Policy = 1, caused an error. (gs_setpd.ps) 3354 [3.62] Setting the PageSize policy to 1 and then trying to set the 3355page size caused an error if FIXEDMEDIA was selected. (gs_setpd.ps) 3356 [3.61] Rotated characters were rendered incorrectly (bug introduced 3357in 3.52). (gstype1.c) 3358 [3.60] currentscreen and currentcolorscreen could give an error if 3359the current screen was set with sethalftone (or, for currentscreen, 3360setcolorscreen). (gs_dps1.ps) 3361 [3.60] Streams could get removed from a bookkeeping list 3362prematurely, and wind up dangling. (zfile.c) 3363 [3.60] Multiple -I switches set the search path incorrectly. 3364(gsmain.c) 3365 [3.60] Fonts could wind up with a pointer to the wrong VM space, 3366causing potential GC or save/restore confusion. (zfont2.c) 3367 [3.60] upath could leave garbage on the stack if it failed. 3368(gs_dps1.ps) 3369 3370[3.61] Extends the client API to allow for pushing values onto the operand 3371stack. (imain.h, gs.c, gsmain.c) 3372 3373[3.61] Defines a .setdefaultscreen procedure that sets the default halftone 3374screen, transfer function, and stroke adjustment for the current device. 3375Changes selectdevice and setpagedevice so that they call .setdefaultscreen; 3376setpagedevice calls .setdefaultscreen before calling the Install procedure, 3377so that Install can set different parameters if it wishes. Note that 3378setdevice does not do this. (gs_init.ps, gs_setpd.ps) 3379 3380[3.60] Speeds up rasterizing characters into the cache a little. 3381(gs_type0.ps) 3382 3383[3.60] Changes the default limit on the size of cached characters from the 3384maximum of (18 points or 5 times the "average" character size) to (18 points 3385or 1% of the total cache size). (gs_init.ps) 3386 3387[3.60] Implements parts of the Type 1 BuildChar callout in C. (gs_type1.ps, 3388zchar.c) 3389 3390</pre><h3><a name="V3.53_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre> 3391 3392Fixes bugs: 3393 [3.62] If a PDF file substituted a calibrated color space for the 3394DeviceGray or DeviceRGB color space using a ColorSpace resource, the 3395PostScript file that pdf2ps produced from that PDF file caused an error. 3396(gs_pdf.ps) 3397 [3.61] Tf set the current text font twice, and interacted with 3398pdf2ps in an awkward way. (gs_pdf.ps, pdf_2ps.ps, pdf_font.ps) 3399 [3.61] If a font had variant Widths, it could get confused in the 3400cache with the underlying font. (pdf_font.ps) 3401 [3.61] If a character appeared twice in an encoding and the font 3402specified different Widths values for the two occurrences, the last Width 3403would be used. We patched this to ignore zero Widths, which is not the 3404correct solution but which almost always produces correct output. 3405(pdf_font.ps) 3406 [3.61] Arrays containing nulls didn't print out correctly (bug 3407introduced in 3.60). (gs_init.ps) 3408 [3.61] Some PDF files contain very large dictionaries, which caused 3409a stackoverflow. (pdf_base.ps) 3410 [3.60] The length of an image's data was sometimes calculated 3411incorrectly, causing an error when converting PDF to PostScript. 3412(pdf_draw.ps) 3413 [3.60] If word spacing and/or text spacing was non-zero, an error 3414could occur. (gs_pdf.ps) 3415 [3.60] Text that was both filled and stroked caused an error. 3416(gs_pdf.ps) 3417 3418[3.61] Speeds up the initial processing of PDF files by caching the map from 3419page numbers to page objects, and by not scanning the outlines if we aren't 3420producing PostScript output. (pdf_2ps.ps, pdf_base.ps, pdf_main.ps) 3421 3422</pre><h3><a name="V3.53_Streams"></a>Streams</h3><pre> 3423 3424Fixes bugs: 3425 [3.60] When closing an encoding filter stream whose target was also 3426a filter, the latter could get called incorrectly with last = 1, possibly 3427more than once, leading to premature EOD markers. (stream.c) 3428 [3.60] The LZW-compatible encoder put out an incorrect end-of-data 3429code. (slzwce.c) 3430 [3.60] The LZW-compatible encoder didn't put out a reset code soon 3431enough. (slzwce.c) 3432 [3.60] Doing a sgets on a closed stream could call sreadbuf, 3433possibly causing an error. (stream.c) 3434 3435</pre><h3><a name="V3.53_Library"></a>Library</h3><pre> 3436 3437Fixes bugs: 3438 [3.63] On 16-bit platforms, the computation of t2 and t3 in 3439gx_curve_x_at_y could overflow, leading to incorrect output. (gxpcopy.c) 3440 [3.61] glyphshow displayed a character with code 0 rather than the 3441requested character (bug introduced in 3.60.) (gschar.c) 3442 [3.61] If trimming white space around a character reduced its 3443raster, the character was garbled in the cache (bug introduced in 3.60.) 3444(gxccman.c) 3445 [3.61] colorimage would incorrectly convert white pixels to black if 3446the image color space was CMYK, the current color space was not CMYK, and 3447the number of bits per pixel was 4 or 8. (gsimage2.c) 3448 [3.61] Type 1 fonts that used the Flex feature applied hints to the 3449path multiple times, causing dropouts, uneven stems, and other problems (bug 3450probably introduced in 3.21). (gstype1.c) 3451 [3.61] If a Type 1 font used the Flex feature within the accent of 3452an accented character defined with seac, the shape of the accent could be 3453distorted. (gxtype1.h, gstype1.c) 3454 [3.61] If a Type 1 font changed hints using the hint replacement 3455facility when the last operation was a closepath, the old hints would be 3456applied a second time, distorting the shape. (gxhint2.c, gxhint3.c) 3457 [3.60] Cached characters sometimes had extra blank space on the 3458left, leading to some unnecessary bit-shuffling when imaging them. 3459(gxccman.c) 3460 [3.60] The list of all-bands commands wasn't initialized/reset 3461properly. (gxclist.c) 3462 [3.60] Because of a typo in a macro formal parameter list, a private 3463name was duplicated. (gsstruct.h) 3464 [3.60] Text display operations didn't update the current character 3465in the enumerator structure during the fastest path through the code. This 3466only matters to one very unusual commercial client. (gschar.c) 3467 3468[3.61] Adds an alternative implementation of the core path filling algorithm 3469that is much faster on objects with curves but doesn't handle Y fattening. 3470This is the implementation that will normally be used for rasterizing 3471characters. This implementation rasterizes curves directly, without 3472flattening them. (gxfixed.h, gxpath.h, gzpath.h, gxdraw.c, gxfill.c, 3473gxpcopy.c) 3474 3475[3.61] Speeds up the flattening of curves substantially by omitting more 3476redundant points. (gxpcopy.c) 3477 3478[3.61] Speeds up character bitmap compression a little more. (gsbitops.h, 3479gdevabuf.c, gsbitops.c, gxccman.c) 3480 3481[3.61] Speeds up anti-aliased graphics a bit by computing a bounding box 3482before converting from oversampling to alpha values, and by speeding up the 3483bounding box computation itself. (gsbitops.h, gdevabuf.c, gsbitops.c, 3484gxccman.c) 3485 3486[3.60] Speeds up getting the side bearing and width of a Type 1 charstring a 3487little. (gxtype1.h, gstype1.c) 3488 3489[3.60] Adds a compile-time option, ALPHA_LSB_FIRST, which causes 3490alpha-sampled characters to be nibble-reversed in the cache. This was 3491created for a specialized application and does not interact well with the 3492rest of the code. (gsbitops.c) 3493 3494[3.60] Substantially speeds up entering anti-aliased characters in the 3495cache, by removing white space before compressing rather than vice versa. 3496(gsbitops.c, gxccman.c) 3497 3498</pre> 3499 3500<h2><a name="Version3.52"></a>Version 3.52 (limited) (10/6/95)</h2> 3501 3502<p> 3503This is an incremental release to fix a few problems in 3.51.

(gs_init.ps) 6991 6992</pre><h3><a name="V3.22_Drivers"></a>Drivers</h3><pre> 6993 6994Fixes bugs: 6995 - The dfax drivers incorrectly set EncodedByteAlign to false. 6996(gdevdfax.c) 6997 - softwareValue and dateTimeValue were declared as byte rather than 6998char. (gdevtfax.c) 6999 7000</pre><h3><a name="V3.22_Platforms"></a>Platforms</h3><pre> 7001 7002Fixes bugs: 7003 - The VMS DEC C compilers declare delete in unixio.h, and doesn't 7004declare unlink anywhere. (stdio_.h) 7005 - The VMS compilers declare malloc and free in stdlib.h, which 7006wasn't being included in malloc_.h. (malloc_.h) 7007 - The SCO Unix C compiler needs both <sys/time.h> and <time.h>. 7008(time_.h) 7009 - The VMS compilers declare abs in stdlib.h, which wasn't being 7010included anywhere. (gshtscr.c) 7011 - The definition for A4 paper in VMS-AXP.MAK was incorrect. 7012(vms-axp.mak) 7013 7014Renames VMS-AXP.MAK as VMS-DECC.MAK, with some changes that make it 7015appropriate for DEC C on both VAX and AXP platforms. (vms-axp.mak => 7016vms.decc.mak) 7017 7018</pre><h3><a name="V3.22_Fonts"></a>Fonts</h3><pre> 7019 7020Fixes bugs: 7021 - gs_kanji.ps got an invalidaccess error. (gs_kanji.ps) 7022 7023</pre><h3><a name="V3.22_Interpreter"></a>Interpreter</h3><pre> 7024 7025Fixes bugs: 7026 - An off-by-1 test in the roll operator caused it to smash the 7027stack if the operand stack had overflowed into additional blocks. 7028(zstack.c) 7029 - The default CIE color rendering dictionary didn't assume a 7030reasonable intermediate (XYZ) space. (gs_lev2.ps) 7031 - CIE color mapping tables weren't traced properly by the garbage 7032collector. (gscie.h, gscie.c, zcie.c) 7033 - If the very last character of a file was a ^M, the scanner 7034(incorrectly) signaled a syntaxerror. (iscan.c) 7035 - If an operator could return both a typecheck and a 7036stackunderflow, it always returned a stackunderflow, which doesn't match 7037the behavior of Adobe interpreters. (opcheck.h, idparam.c, interp.c, 7038iutil.c, z*.c) 7039 - astore, dictstack, and execstack could return a spurious 7040invalidaccess error (or fail to detect an invalid access) if the operand 7041stack had overflowed into additional blocks. (istack.c) 7042 - The garbage collector didn't relocate pointers to names! (Bug 7043introduced in 3.20.) (iname.h) 7044 - If the dictionary stack overflowed into additional blocks, the 7045cached value pointer for a name could get set incorrectly, and also not get 7046relocated by the garbage collector. (idict.c) 7047 - If the dictionary stack overflowed into additional blocks, the 7048post-GC fixup of cached value pointers in names could cause an addressing 7049error. (igc.c) 7050 - With the -Z? switch set, the garbage collector could incorrectly 7051report that objects or strings weren't in any chunk. (igc.c) 7052 - << /a 1 /a 2 >> /a get gave the value 2 rather than 1. 7053(gs_init.ps) 7054 - Numbers in binary object sequences and encoded number arrays 7055didn't work properly on machines where sizeof(short) != 2 or sizeof(long) 7056!= 4. (ibnum.c) 7057 - The put operator for dictionaries allowed null as a key. 7058(idict.h, idict.c) 7059 - >> didn't give an error if there were an odd number of values on 7060the stack above the next mark. (gs_init.ps) 7061 - Operations that explicitly freed ref objects (setting a CIE 7062colorspace, resizing a dictionary, popping a block off a stack) could 7063corrupt storage. (ialloc.c) 7064 - The -Z@ switch, which fills freed blocks with a recognizable bit 7065pattern, could incorrectly overwrite freed blocks in previous save levels, 7066causing invalid memory accesses. (ialloc.c) 7067 - Since streams freed by a restore weren't marked as free, they 7068could confuse the garbage collector and lead to invalid memory accesses. 7069(zfile.c) 7070 - If one of the built-in dictionaries overflowed during 7071initialization, no error was reported -- entries were simply discarded. 7072(iinit.c) 7073 - If the level2.dev feature was combined with certain other 7074features, the current languagelevel was 2 when some gs_*.ps files were 7075loaded, causing them to load incorrectly. (gs_btokn.ps, gs_setpd.ps) 7076 - If readline read a line that ended with only a CR (no LF) 7077followed by an end-of-file, it incorrectly closed the stream. (zfileio.c) 7078 7079Adds a .cond operator, similar to the Lisp multi-arm conditional. 7080(zcontrol.c) 7081 7082Adds a .makeglobaloperator operator, allowing the definition of operator 7083procedures in local VM that turn into global operators, provided the save 7084level is zero. (iref.h, opdef.h, iinit.c, interp.c, zmisc.c) 7085 7086Note: the fix for returning typecheck vs. stackunderflow requires that all 7087operators (or other code) that uses return_error(e_typecheck) to indicate 7088an incorrect object type on the operand stack must change this to 7089return_op_typecheck(op), where op points to the operand. THIS IS A 7090NON-BACKWARD-COMPATIBLE CHANGE. 7091 7092Implements string array and name array parameters for parameter lists. 7093(gsparam.h, iparam.c) 7094 7095Brings filterdict inside the INITIAL_DICTIONARIES conditional. (iinit.c) 7096 7097Adds a .currentscreenlevels operator that returns the number of 7098distinguishable halftone levels. (zht.c) 7099 7100</pre><h3><a name="V3.22_Streams"></a>Streams</h3><pre> 7101 7102Fixes bugs: 7103 - The 2-D case of CCITTFaxDecode could get confused by an input 7104data buffer boundary that fell immediately after a horizontal code. 7105(scfd.c) 7106 - The LZW decoder didn't detect invalid data unless DEBUG was 7107selected at build time. (slzwd.c) 7108 7109</pre><h3><a name="V3.22_Library"></a>Library</h3><pre> 7110 7111Fixes bugs: 7112 - The clipping region accumulator could refer to a clipping 7113rectangle even after it had been freed. (No effect on execution unless the 7114-Z@ switch was selected.) (gxacpath.c) 7115 - setbbox expanded the bounding box, but didn't place a limit on 7116further path elements, if the current path wasn't empty. (gsdps1.c) 7117 - setbbox didn't make sufficient allowance for rounding. 7118(gsdps1.c) 7119 7120Implements the ProcessColorModel parameter (read-only) for all devices. 7121(gsdparam.c) 7122 7123Adds a gs_currentscreenlevels procedure that returns the number of 7124distinguishable halftone levels.

It also includes a substantial 7132improvement in the Type 1 font hinting algorithms. This release was not 7133distributed to the public. 7134 7135<h3><a name="V3.21_Documentation"></a>Documentation</h3><pre> 7136Fixes bugs: 7137 - The `man' page referred to gnu.ghostscript.bug rather than 7138comp.lang.postscript. (gs.1) 7139 7140Documents the special entries in operator definition tables that allow 7141switching dictionaries. (opdef.h) 7142 7143</pre><h3><a name="V3.21_Procedures"></a>Procedures</h3><pre> 7144 7145Moves the definition of JSRCDIR to the individual platform makefiles, to 7146make it easier to change on platforms that don't have file links. (*.mak) 7147 7148</pre><h3><a name="V3.21_Utilities"></a>Utilities</h3><pre> 7149 7150Fixes bugs: 7151 - ansi2knr didn't recognize that a line ending with } couldn't be a 7152function definition. (ansi2knr.c) 7153 - ps2epsi always returned an empty bounding box. (ps2epsi, 7154ps2epsi.bat) 7155 7156</pre><h3><a name="V3.21_Drivers"></a>Drivers</h3><pre> 7157 7158Fixes bugs: 7159 - The bitrgb device had an invalid depth of 3. (gdevbit.c) 7160 7161Replaces the color mapping code in the X driver with a much faster 7162algorithm, courtesy of Tim Theisen.

(os2.mak) 7174 7175</pre><h3><a name="V3.21_Fonts"></a>Fonts</h3><pre> 7176 7177Fixes bugs: 7178 - wrfont.ps, and hence bdftops, didn't write out the FontType or 7179PaintType. (Bug introduced since 2.6.1) (wrfont.ps) 7180 - wrfont.ps omitted a 'begin' and 'end', causing -! or -| to be 7181undefined when the font was loaded. (Bug introduced since 2.6.1) 7182(wrfont.ps) 7183 7184</pre><h3><a name="V3.21_Interpreter"></a>Interpreter</h3><pre> 7185 7186Fixes bugs: 7187 - make_tasv_old called make_tasv_new with extra arguments. 7188(store.h) 7189 - currentcacheparams only returned 2 values instead of 3. 7190(zfont.c) 7191 - ustroke popped one element too many off the stack if a matrix was 7192supplied. (zupath.c) 7193 - inu[eo]fill popped one element too many off the stack. 7194(zupath.c) 7195 - The color rendering dictionary was initialized to null rather 7196than a valid dictionary. (gs_lev2.ps) 7197 - An invalid IODevice resource named "9" got created. (gs_res.ps) 7198 - bytesavailable often caused an error rather than returning -1. 7199(zfileio.c, stream.c) 7200 - The insideness testing operators always returned true if the 7201aperture was defined by a user path rather than a point. (zupath.c) 7202 - If INITIAL_DICTIONARIES was defined in the makefile, the 7203definition of the initial_dictionaries array was missing a comma. 7204(iinit.c) 7205 - Even if userdict appeared in INITIAL_DICTIONARIES, gs_init.ps set 7206its maxlength to 200. (gs_init.ps) 7207 - Setting a CIE color space left a garbage value on the stack. 7208(zcie.c) 7209 - If a file or filter was opened and then closed, opening a file 7210subsequently within a 'save' could lead to a memory access error in the 7211garbage collector. (zfile.c) 7212 - Setting an Indexed or Separation color space could cause a crash 7213either in the garbage collector or when printing out the e-stack. 7214(icsmap.h, zcsindex.c, zcssepr.c) 7215 - Invoking a filter with an invalid data source or sink could cause 7216a memory access error (bug introduced in 3.20). (zfilter.c) 7217 - Invoking stringwidth on a font whose BuildChar procedure did a 7218save could cause a memory manager error or infinite loop, because 7219stringwidth attempted to use an inapplicable shortcut. (gschar.c) 7220 - The bounding box for rendering stroked Type 1 characters didn't 7221take square caps and miter joins into account. (gs_type1.ps) 7222 - Invoking filter with DCTDecode or DCTEncode could cause an 7223addressing error if no dictionary argument was supplied. (zfdctd.c, 7224zfdcte.c) 7225 - The Generic resource, the Font resource, and half a dozen 7226resources with no predefined instances all shared the same Instances 7227dictionary. (gs_res.ps) 7228 - The temporary null device allocated for stringwidth was never 7229freed. (gschar.h, gschar.c, zchar.c) 7230 - Internal operators, and structures that might be freed on stack 7231unwinding, could "escape" from the e-stack. (zcontrol.c, ztype.c) 7232 - makefont and scalefont didn't properly handle a font whose 7233Encoding had been changed. (bfont.h, zfont.c, zfont2.c) 7234 - Type 1 fonts with PaintType = 2 incorrectly checked for an xfont. 7235(gxfont.h, gschar.c, gsfont.c, zchar1.c, zfont1.c, zfont2.c) 7236 - Specifying a string argument with -d...=(...) or -d...=<...> 7237would cause an invalidaccess error. (gs.c) 7238 - The environment for encapsulated jobs didn't rebind quit to stop 7239in userdict. (gs_lev2.ps) 7240 - restore didn't deal properly with open files on the e-stack. 7241(zvmem.c) 7242 - Even with the '-' switch, Ghostscript would try to read ahead in 7243the input stream rather than processing input character-by-character. 7244(ziodev.c) 7245 - If an error occurred with a unreadable dictionary on any stack, 7246the standard error printer would get into an error loop and exit the 7247interpreter. (gs_init.ps) 7248 - The for_roots macro in igc.c used ap rather than mem as its 7249second formal parameter. (This typo had no effect on the executable 7250program.) (igc.c) 7251 - If saving the stacks for an error caused a GC request, a value 7252could get stored into an improper variable on the C stack, causing havoc. 7253(interp.c) 7254 - setdash checked to make sure that the distance array had read 7255access; Adobe interpreters don't check this. (zgstate.c) 7256 - The roots for gs_run_string and gs_interpret weren't registered 7257properly, which could cause a dangling reference in the case of a restore 7258whose save had been done earlier. (gsmain.c, interp.c) 7259 7260Adds an OpenOutputFile Boolean device parameter for printer devices; if 7261true, the device opens the OutputFile at the time the device is opened, 7262instead of waiting for the first showpage. This helps with synchronization 7263when the OutputFile is a pipe. (gdevprn.h, gdevprn.c) 7264 7265Changes the BEGIN/END_OP_DEFS macros to require an explicit { and } at each 7266use. (gsmain.c, interp.c, z*.c) 7267 7268Arranges things so that the operators that the interpreter handles 7269specially are assigned the first N operator indices [internal change only]. 7270(interp.h, iinit.c, interp.c) 7271 7272Changes the operators max and min to .max and .min, to avoid conflicts with 7273PostScript programs that use these names for variables and also use 'bind'. 7274THIS IS A NON-BACKWARD-COMPATIBLE CHANGE from programs that depend on 7275'bind' binding in these operators; however, we have also defined procedures 7276max and min that just call the operators, which should take care of any 7277ordinary code. (*.ps, zrelbit.c) 7278 7279</pre><h3><a name="V3.21_Streams"></a>Streams</h3><pre> 7280 7281Fixes bugs: 7282 - The pfb_state pointer in the eexecDecode filter state wasn't 7283marked as traceable for the garbage collector. (sfilter.h) 7284 - The eexec decoding filter could access invalid memory or return 7285garbage under some conditions. (Bug introduced in 3.12.) (zmisc1.c) 7286 - The eexec decoding filter would incorrectly ask for more input if 7287the output buffer was full. (seexec.c) 7288 7289</pre><h3><a name="V3.21_Library"></a>Library</h3><pre> 7290 7291Fixes bugs: 7292 - Some compilers reserve the word 'try'. (gshtscr.c) 7293 - Some compilers don't like line continuations (\) within a 7294preprocessor macro formal parameter list. (gdevprn.h, gxdevice.h) 7295 - Memory devices created with an inverted palette (0=white, 72961=black) interchanged white and black in fill operations. (gdevmem1.c) 7297 - The 'bits' variable in mem_mono_copy_mono was unused on 7298little-endian machines. (gdevmem1.c) 7299 - Some garbage collector procedures were declared 'private' 7300inconsistently. (gscie.c) 7301 - The new anti-aliased text capability accidentally caused all 7302characters to be oversampled. (gschar.c) 7303 - Type 1 fonts with PaintType = 2 and StrokeWidth = 0 came out with 7304many pixels missing because of oversampling. (gschar.c) 7305 - Type 1 font stem hints were not being processed correctly. 7306(gstype1.h, gxtype1.h, gstype1.c, gxhint2.c, gxhint3.c, gxpath.c) 7307 - The tracing message for 9/7 composite fonts incorrectly 7308identified them as 1/7 fonts. (gschar0.c) 7309 - If a 1/7 or 9/7 composite font was a child of a non-modal font, 7310the font number of the child font was computed incorrectly. (gschar0.c) 7311 7312Splits up the various memory devices into one file per depth [internal 7313change only].

(gs_lev2.ps) 8396 - The declaration for swap_entry used a typedef name as a formal 8397parameter, which upset some compilers. (zmisc2.c) 8398 - Including the ccinit feature could cause the garbage collector to 8399make an invalid access. (stream.c) 8400 - The check for t_[a]struct types in ztype.c was incorrect. 8401(ztype.c) 8402 - After the collection of halftone samples, temporary data 8403structures were freed incorrectly.

(gschar.c) 8433 - joins on stroked lines were incorrect if the device coordinate 8434system mapped +Y to +Y. (gxstroke.c) 8435 - If gsmisc.c supplied versions of missing library routines, they 8436could clash with the names of the real ones if those were present 8437unexpectedly. (memory_.h, gsmisc.c) 8438 - The initialization expression for is_open in the 8439dev_init_misc_open macro included a cast, which some compilers don't allow. 8440(gxdevice.h, gsdevice.c, gxclip2.c, gxpcmap.c) 8441 - In Type 1 fonts, character that specified their side bearing and 8442width with sbw rather than hsbw gave an invalidfont error.
