Changes marked with a * were made available as patches to a 748previous release. 749 750<hr> 751 752<h2><a name="Version5.99"></a>Version 5.99 (beta) (1999-12-18)</h2> 753 754<h3><a name="5.99_Incompatible_changes"></a>Incompatible changes</h3><pre> 755 756(Procedures) 757 - All platform-specific makefiles must now define the Q macro. 758 - Ghostscript now exits with an error status if an error occurs in a 759file named on the command line, a -c command, or piped input. 760(Utilities) 761 - ps2epsi now disables setpagedevice: the bounding box of the EPSI 762output file is recorded only in the %%BoundingBox comment. 763(Drivers) 764 - The return type of gdev_vector_close_file is changed from void 765to int. 766(Interpreter) 767 - The name of the predefined stochastic halftone is changed to 768StochasticDefault. (This change was actually made in 5.98.) 769 - The compht feature is replaced by stocht. 770 - Font searching now looks in FontResourceDir. 771 - The ASCIIHexEncode filter now produces upper-case output. 772(Library) 773 - The type returned by compiled halftone resource access procedures 774is changed. 775 776</pre><h3><a name="5.99_Documentation"></a>Documentation</h3><pre> 777 778Fixes problems: 779 - A stray character had gotten added to the beginning of a file. 780(doc/Use.htm) 781 - Many minor HTML errors had crept in. (doc/*.htm, doc/gsdoc.el) 782 783Updates the docmentation on the mswinpr2 driver. (doc/Devices.htm) 784 785Notes that GNU make currently does not work on OpenVMS. (doc/Make.htm) 786 787Documents the fact that x/y_pixels_per_inch are deprecated. (gxdevcli.h) 788 789Documents certain bugs in ps2pdf. (doc/Ps2pdf.htm) 790 791Documents the addition of FontResourceDir to the font search process. 792(doc/Use.htm) 793 794Documents the new arrangement for B paper sizes. (doc/Psfiles.htm, 795doc/Use.htm, doc/gs-vms.hlp, man/gs.1) 796 797Removes the "under development" warning from the text API and 798get_bits_rectangle documentation, and adds a little more detail. 799(doc/Drivers.htm) 800 801Adds new user-contributed documentation for installing and using Ghostscript 802fonts with X Windows. (doc/Fonts.htm, doc/Readme.htm, doc/Use.htm) 803 804Adds building with the Watcom compiler to the release process. 805(doc/Release.htm) 806 807Adds an "Improving performance" section to the user documentation. 808(doc/Use.htm) 809 810Adds a note to the C style guide about order of evaluation. 811(doc/C-style.htm) 812 813Documents the new stocht.ps file. (doc/Psfiles.htm) 814 815</pre><h3><a name="5.99_Procedures"></a>Procedures</h3><pre> 816 817Fixes problems: 818 - A missing dependency caused builds on certain platforms to fail. 819(int.mak) 820 - $(EXP) was missing before various utility invocations. (int.mak) 821 - VMS converts all unquoted arguments to lower case. In order to 822work around this, we have added a platform-specific makefile macro Q, which 823is defined as a quote mark on VMS and as an empty string on all other 824platforms, and used it to quote the few mixed-case values in the makefiles. 825We removed the obsolete QQ macro from os2.mak as well. (cfonts.mak, 826dvx-head.mak, int.mak, openvms.mak, openvms.mmk, os2.mak, unixhead.mak, 827wccommon.mak, winlib.mak) 828 - PSRCDIR was incorrectly referenced as PNGSRCDIR in one place. 829(all-arch.mak) 830 - winint.mak had a conditional that Watcom's make program didn't 831accept. (winint.mak) 832 833Adds a makefile entry to allow compilation with libpng 1.0.5. (libpng.mak) 834 835Updates the Borland C++ makefile to work with C++Builder 4. (bcwin32.mak) 836 837Updates the Unix installation makefile to install stocht.ps. (unixinst.mak) 838 839</pre><h3><a name="5.99_Utilities"></a>Utilities</h3><pre> 840 841Fixes problems: 842 - ps2epsi didn't disable setpagedevice. (lib/ps2epsi) 843 - geninit needed <stdlib.h> for 'exit'. (geninit.c) 844 - Some invocations of utilities didn't deal with VMS's habit of 845converting arguments to lower case. (geninit.c, cfonts.mak) 846 - The ps2pdf*.bat files didn't produce a usage message if no 847arguments were provided. (lib/ps2pdf.bat, lib/ps2pdf12.bat, 848lib/ps2pdf13.bat) 849 - Removes some warnings from the Windows uninstaller. 850(dwuninst.cpp) 851 852Upgrades the halftone compiler to handle Type 5 halftones.

(gsfunc0.c) 1973 - The cached is_monotonic value in a function head was incorrectly 1974declared bool rather than int. (gsfunc.h) 1975 - The clip operators didn't always recognize empty clipping regions: 1976sometimes they retained a 1-pixel-wide region. (gxcpath.c) 1977 - The bbox device could get into a recursion loop if it had a 1978non-null target with a non-standard fill_path procedure. (gdevbbox.c) 1979 - The procedure u32 was defined in two places. (gsutil.h, 1980gdevpsdt.c, gsutil.c, gstype42.c) 1981 - The DataSource member of a sampled function wasn't reported to the 1982garbage collector.

(gxfill.c, gxhint3.c) 1989 - In a few places, (fixed-point) coordinates were truncated towards 1990zero rather than taking the floor. (It's likely that this had no effect.) 1991(gxfill.c, gxpcopy.c) 1992 - The join and cap values weren't taken into account when dividing a 1993stroked path into bands, possibly causing some caps or joins to be dropped 1994if they fell exactly at band boundaries. (gxclpath.c) 1995 - An arithmetic overflow in gx_adjust_if_empty could produce 1996incorrect output. (gxfill.c) 1997 - Because the bbox device used a Y-inverted coordinate system, it 1998could produce incorrect results for out-of-bounds coordinates. (gdevbbox.c) 1999 - The default font_info procedure didn't compute MISSING_WIDTH if 2000IS_FIXED_WIDTH wasn't requested. (gsfont.c) 2001 - space_params wasn't managed properly, causing problems if the 2002device altered the default values.

(gxtype1.h, gstype1.c) 7875 - The memory-based band list allocator failed to return an error 7876code from memfile_next_blk. (gxclmem.c) 7877 - When recovering from a low-band-list-memory condition while 7878writing an image, the record of the current image enumeration 7879(cdev->image_enum_id) wasn't updated.

(gxclipm.c) 7884 7885Speeds up masked images by doing mask clipping before halftoning, using a 7886more efficient mask scanning algorithm, and checking for vertical blocks of 78871s. (gxclipm.c) 7888 7889Speeds up ImageType 4 images greatly by incorporating the color-key check 7890into the ImageType 1 rendering code. NOTE: the 12-bit case has not been 7891tested.

(gscie.h) 7922 7923Adds a unique ID to color spaces to allow fast detection of reselecting the 7924same color space. This matters for certain client code that repeatedly 7925reselects the same color space, since selecting certain color spaces is 7926expensive. (gscpixel.h, gscspace.h, gxcspace.h, gscolor2.c, gscpixel.c, 7927gscscie.c, gscspace.c, gspcolor.c, gsstate.c, gximage2.c) ****** NEED TO FIX 7928gxclrast.c TO ALLOC INDEXED COLOR SPACE ****** 7929 7930Speeds up setting Pattern color spaces, by bypassing the install code for 7931the base space.

This matters for certain client code that does this repeatedly. 7935(gscie.h, gscrd.h, gscrd.c) 7936 7937Detects setting the CRD to one with identical PQR components, and bypasses 7938an expensive setup step. (gscie.c) 7939 7940Speeds up converting pixels between representations (gx_get_bits_copy) for 7941devices with up to 4 bits per pixel, by caching the pixel values. 7942(gdevdgbr.c) 7943 7944Speeds up the slow default RasterOp algorithm a little. (gdevdrop.c) 7945 7946Defines standard mapping procedures for 1-bit-per-component CMYK colors. 7947Other code can then test for the presence of these procedures and use more 7948efficient algorithms. (gxdevice.h, gxcmap.c) 7949 7950Speeds up some algorithms in the bbox device by making some recursive calls 7951use a pure color rather than a client-supplied one. (gdevbbox.h, gdevbbox.c) 7952 7953Adds a cache for the black and white pixel values to the device structure. 7954(gxdevcli.h, gxdevice.h, gdevalph.c, gdevnfwd.c, gsdparam.c, gxdcolor.c) 7955 7956Makes the code for colored halftones a little more readable. (gxcht.c) 7957 7958Speeds up color mapping for CMYK devices by copying the color mapping 7959procedures into forwarding devices, when applicable. (gdevcmap.c, 7960gdevmem.c, gsdevice.c, gxclip.c) 7961 7962Removes some compiler warnings (mostly about "uninitialized" variables). 7963(gxcldev.h, gsdevmem.c, gsshade.c, gstype42.c, gxclpath.c, gxfill.c, 7964gximage3.c, gxpath2.c, gxpcopy.c) 7965 7966For the benefit of certain client code that commonly sets a CRD and then 7967doesn't use it, makes loading of the joint CIE caches lazy (at the library 7968level). (gscie.h, gscie.c) 7969 7970Changes CIE color restriction from a macro to a procedure, since it is 7971rarely used. (gscie.c) 7972 7973Adds code and structures for detecting when CIE Decode and/or Encode 7974procedures are simply linear transformations, which would allow collapsing 7975them into the adjacent matrix, but doesn't actually do the collapsing. 7976(gscie.h, gscie.c) 7977 7978Speeds up color halftoning by pre-computing the mask of planes that need to 7979be halftoned, and preconverting multi-plane halftones to binary or solid 7980colors when possible. (gsdcolor.h, gxcht.c, gxdcolor.c, gxdither.c, gxht.c) 7981 7982Optimizes color mapping for 1-bit-per-component CMYK halftones. (gxcht.c) 7983 7984Optimizes null RasterOp sources for black = 1 as well as black = 0. 7985(gxdcolor.c) 7986 7987Modifies the standard allocator so it keeps track of large free blocks as 7988well as small ones, and uses them to satisfy requests when appropriate. 7989(gxalloc.h, gsalloc.c) 7990 7991Speeds up the horizontal bitmap replication code a bit.

(zcrd.c, ztype.c) 9865 - Contexts were always allocated in global VM (should be local VM), 9866and were freed in the current VM (should be local VM). Fixing this required 9867changing some internal interfaces defined in icontext.h. (icontext.h, 9868icontext.c, interp.c, zcontext.c) 9869 - restore did some unnecessary gsaves. (zvmem.c) 9870 - Creating a new context didn't initialize the graphics state 9871properly, and didn't do the first gsave that grestoreall relies on. 9872(gs_dps.ps) 9873 - The bookkeeping for open files didn't work with multiple contexts. 9874Fixing this required a substantial (simplifying) redesign of the 9875interpreter's bookkeeping for streams in general: this may have introduced 9876new bugs. (files.h, ireclaim.c, isave.c, zfile.c) 9877 - fork didn't copy the graphics state stack.

(gxpath.h, gxcpath.c, gxpath.c) 10105 - As always, gcc failed to report some static/non-static 10106inconsistencies. However, to my dismay, I find that the ANSI C standard 10107allows these, so I'll have to stop complaining about them. (gxclimag.c, 10108gxclipm.c) 10109 - As always, gcc failed to report some signed/unsigned char * 10110mismatches. (gdevpdfi.c, gsparam.c) 10111 - A loop counted on a non-existent zero value to mark the end of the 10112IODevice table. (gsiodev.c) 10113 - Some needed #includes of memory_.h were missing. (gdevddrw.c, 10114gscolor2.c, gscrdp.c, gscspace.c, gxclipm.c, gximage3.c, gxshade4.c) 10115 - Pattern device colors didn't have access to the original halftone 10116phase, making it impossible to handle non-standard X/YStep correctly. 10117(gsdcolor.h, gspcolor.c) 10118 - Pattern filling disregarded the phase. THIS MAY UNDO A FIX MADE 10119IN 5.02. WE NEED TO RE-TEST PATTERNS CAREFULLY. (gxp1fill.c) 10120 - restore did some unnecessary gsaves. (gsstate.h, gsstate.c) 10121 - The reference counting macros could read from an object after 10122freeing it. (gsrefct.h) 10123 - setgstate and currentgstate freed the view clipping path, which 10124they shouldn't do. (gsstate.c) 10125 - If no view clipping path was set, viewclippath returned the entire 10126extent of the device, not the imageable area. (gxpath.h, gsdps.c, gspath.c) 10127 - Assigning one stack-allocated path to another incorrectly wound up 10128sharing their segments. (gxcpath.c, gxpath.c) 10129 - dot_length_absolute was incorrectly declared as float rather than 10130bool. (gxline.h) 10131 - The test for varying-depth banded images was incorrect, causing 10132varying-depth images to be treated as constant-depth. (This only affected 10133ImageType 3 images.) (gxclimag.c) 10134 - Failure to clamp Y values when processing banded images could 10135cause crashes or invalid band list data. (gxclimag.c) 10136 - The changes in gsparam.c introduced in 5.23 made the coercion of 10137int arrays to float arrays fail. (gsparam.h, gsparam.c) 10138 - Interpolated banded images could be transmitted incompletely, 10139causing narrow stripes to be chopped out of their rendering. (gxclimag.c) 10140 - FunctionType 0 functions with 32-bit samples didn't read their 10141data correctly. (gsfunc0.c) 10142 - Lattice-form Shadings with packed coordinates could crash or 10143produce incorrect results. (gxshade.c) 10144 - Lattice-form Shadings with packed coordinates always returned an 10145error. (gxshade4.c) 10146 - If the PaintProc of a Pattern or a Form, or a CharString 10147procedure, or a similar callback copied the current graphics state with 10148gstate or currentgstate, a dangling reference to the device could result. 10149Fixing this required adding a reference count to devices: internally created 10150devices initialize it to 0, externally visible devices initialize it to 1. 10151THIS IS A DELICATE CHANGE AND WILL PROBABLY HAVE A BUG TAIL. (gsdevice.h, 10152gxdevcli.h, gxdevice.h, gdevmem.c, gdevmrop.c, gdevnfwd.c, gschar.c, 10153gsdevice.c, gsmemory.c, gspaint.c, gsstate.c, gxacpath.c, gxccman.c, 10154gxclip.c, gxmclip.c, gxpcmap.c) 10155 - The return_if_error macro referred to code rather than code_. 10156(gserror.h) 10157 - Non-monotonic halftones didn't allocate enough slots in the 10158halftone cache. (gxht.c) 10159 - setpagedevice with a 0-size page didn't fail. Fixing this 10160required making the nullpage device provide explicit InputAttributes. 10161(gdevnfwd.c) 10162 - Halftone angles were often slightly off. (gshtscr.c) 10163 - Banded fill_mask operations (used for characters) were sometimes 10164broken. This bug was obviously introduced since 5.10; I'm surprised that it 10165didn't have more serious effects. (gxclread.c) 10166 - Partially transparent patterns didn't work with non-default 10167RasterOp values. (gxp1fill.c) 10168 - The default implementation of strip_copy_rop didn't handle color 10169space conversion properly. (gdevmrop.c) 10170 - Hint replacement could cause the initial moveto and final 10171closepath of a Type 1 outline to differ, confusing the filling code. 10172(gxhint3.c) 10173 - Interpolated images were truncated at the bottom. (bug probably 10174introduced in 5.23) (gxiscale.c) 10175 - Using an unsigned type for the index passed to enum_ptrs 10176procedures caused comparisons against signed values to be incorrect. 10177(gsstruct.h) 10178 10179Rewrites the rectangle list and mask clipping algorithms to use callback 10180procedures rather than macros. The rectangle list source code grew by 20%, 10181but the compiled code shrank from 10K to less than 4K; the mask clip source 10182code and compiled code both shrank. (gxclip.h, gxmclip.h, gxclip.c, 10183gxclip2.c, gxclipm.c, gxcpath.c) 10184 10185Removes all remaining uses of _ds and _ss.

(gdebug.h, gsht1.c, gsmisc.c, gspaint.c, 10195gxcht.c, gxht.c, gxpcmap.c) 10196 10197Changes the num_components member of the color space structure to a 10198procedure, which is needed because DeviceN color spaces have a variable 10199number of components; also makes Pattern spaces return -1 - the correct 10200num_components instead of -1. This is a NON-BACKWARD-COMPATIBLE CHANGE. 10201Also adds a base_space procedure. (gxcspace.h, gscdevn.c, gscolor1.c, 10202gscolor2.c, gscpixel.c, gscscie.c, gscsepr.c, gscspace.c, gspcolor.c, 10203gxiinit.c, gxiscale.c) 10204 10205Changes all groups of statistic-gathering variables to be structure 10206variables named stats_*. (gxclip.c, gxclist.c, gxclpath.c, gxfill.c, 10207gxifast.c) 10208 10209Starts to pull apart gs_makebitmap/pixmappattern to remove the dependency on 10210masked images. (gspcolor.c) 10211 10212Splits the C heap allocator from generic allocator support. (gsmemory.c, 10213gsmalloc.c) 10214 10215Removes all uses of far_data other than references to device (but not 10216device2) prototypes. (gdevmem.h, gdevmrop.h, gxdevcli.h, gconf.c, 10217gdevabuf.c, gdevht.c, gdevm*.c, gdevmpla.c, gdevmrop.c, gdevnfwd.c, 10218gsbittab.c, gsflip.c, gsroptab.c, gxcht.c) 10219 10220Adds a streams member to gs_ref_memory_t. The library doesn't use this, but 10221it greatly simplifies the interpreter's bookkeeping. (gsalloc.h, gxalloc.h, 10222gsalloc.c) 10223 10224Adds some more opaque types to the graphics state structure, rather than 10225using naked struct types. (gsccolor.h, gzstate.h) 10226 10227Introduces the notion of the "effective clip path" in a graphics state. 10228Painting operators should now call gx_effective_clip_path rather than using 10229the clip_path member directly. (gxpath.h, gschar.c, gsdps1.c, gsimage.c, 10230gspaint.c, gspath.c, gxccache.c, gxpaint.c) 10231 10232Implements view clipping. (gzstate.h, gspath.c, gsstate.c) 10233 10234Starts to pare down the fit_* macros in gxdevice.h, since some people feel 10235strongly they are hard to follow, and also adds BEGIN/END wrapping. 10236(gxdevice.h, gdevabuf.c, gdevmem.c, gxclpath.c) 10237 10238Refactors the structure definition macros in anticipation of moving to a 10239more table-driven approach. Replaces ENUM_CALL, ENUM_RETURN_CALL, and 10240RELOC_CALL with ENUM_USING and RELOC_USING. (gsstruct.h, gdevmem.c, 10241gshtscr.c, gxcpath.c, gxiinit.c) 10242 10243Sketches a table-driven rather than procedural representation for GC 10244descriptors. We believe this will improve readability, reduce code size, 10245and perhaps reduce cache thrashing during garbage collection. This requires 10246a NON-BACKWARD-COMPATIBLE CHANGE to the enum_ptrs, reloc_ptrs, and 10247clear_marks procedures (to add the structure descriptor as a parameter). 10248This should not affect any ordinary clients, because they should already 10249define these procedures using the macros in gsstruct.h, which *are* 10250backward-compatible; however, they do affect two internal clients that use 10251their own type tags with unions (color spaces and device colors). 10252(gsstrtab.h, gsstruct.h, gsalloc.c, gsstrtab.c) 10253 10254Updates color spaces for the change in enum_ptrs and reloc_ptrs. 10255(gxcspace.h, gscdevn.c, gscolor1.c, gscolor2.c, gscpixel.c, gscscie.c, 10256gscsepr.c, gscspace.c, gspcolor.c) 10257 10258Updates device colors for the change in enum_ptrs and reloc_ptrs. 10259(gsdcolor.h, gxdcolor.h, gxpcolor.h, gspcolor.c, gxcht.c, gxcmap.c, 10260gxdcolor.c, gxht.c, gxp1fill.c) 10261 10262Implements a hit detection device at the library level. (gserrors.h, 10263gdevhit.c) 10264 10265Changes some configuration parameters from #defines to statics. (gschar.c) 10266 10267Changes "simple" structures so they no longer have 0 for the enum_ptrs or 10268reloc_ptrs procedure. This is a NON-BACKWARD-COMPATIBLE CHANGE for 10269structure-definers that don't use the macros in gsstruct.h (of which there 10270shouldn't be any). (gsstruct.h, gsalloc.c) 10271 10272Adds the structure type name to the debugging printout for freeing objects. 10273(gsalloc.c) 10274 10275To help in debugging, changes all uses of 10276 #define ss ((stream_xxx_state *)st) 10277to 10278 stream_xxx_state * const ss = (stream_xxx_state *)st; 10279(gxclread.c) 10280 10281Removes all uses of 'near' from the library: if short and long calls have 10282different formats, we rely on the compiler to generate the most efficient 10283one. (gscie.c, gscoord.c, gsimpath.c, gsstate.c, gstype2.c, gxclpath.c, 10284gxclread.c, gxfill.c, gxhint1.c, gxhint2.c, gxhint3.c, gxstroke.c) 10285 10286Adds 'inline' to stdpre.h, defined as the empty string on compilers other 10287than the ones we know accept it. (stdpre.h) 10288 10289Adds printout of the subrectangle to ImageType 1 tracing. (gxiinit.c) 10290 10291Replaces a few uses of gs_memory_default with dev->memory. (gdevdbit.c, 10292gxclread.c) 10293 10294Improves support for halftone objects not associated with graphics states. 10295This involves a minor change to the definitions of gs_spot_halftone and 10296gs_threshold_halftone, to define the transfer function as a closure. This 10297is slightly NON-BACKWARD-COMPATIBLE in that it requires clients to set 10298transfer_closure.proc to 0 if they also set transfer to 0. NOTE: the API 10299defined in gshtx.h is subject to future change. (gscsepnm.h, gshtx.h, 10300gxdht.h, gxfmap.h, gxht.h, gxtmap.h, gscolor.c, gsht.c, gsht1.c, gshtx.c) 10301 10302Changes the Bezier approximation of arcs to cut arcs at absolute multiples 10303of 90 degrees rather than at intervals of 90 degrees (e.g., an arc from 45 10304to 105 would now be cut at 90 rather than being treated as a single 1030560-degree curve) in order to produce more uniform output and also to ensure 10306that the bounding box for arcs is more accurate (to pacify the Genoa FTS). 10307(gxfarith.h, gsmisc.c, gspath1.c) 10308 10309Replaces all remaining uses of do { ... } while (0) with BEGIN ... END. 10310(gsbitops.h, gsdsrc.h, gserror.h, gsmdebug.h, gsrect.h, gxcldev.h, gxfunc.h, 10311gxop1.h, gxtype1.h, gsalphac.c, gsshade.c, gstype2.c, gstype42.c, 10312gxclread.c, gxcpath.c, gximage4.c, gxpath.c) 10313 10314Adds a user-defined halftone type, to support non-monotonic halftones. We 10315could make any of the following structures fully object-oriented: 10316 - Halftones (client level) 10317 - Halftone orders (device level, but not rendered) 10318 - Device halftones (device level, fully rendered) 10319The right place to do this for non-monotonic halftones, which are specified 10320directly by bit masks, is at the device halftone level. However, there are 10321too many places that know too much about the implementation of device 10322halftones and halftone orders right now. WE NEED TO REVISIT THIS AFTER THE 103235.1x CODE BRANCH IS TERMINATED. SHOULD ALSO CONVERT UNION TO TYPED UNION 10324FOR GC -- CODE IS DUPLICATED IN gsht.c VS gshtx.c. (gxdht.h, gxht.h, 10325gxhttype.h, gshtx.h, gsht.c, gsht1.c, gshtx.c) 10326 10327Moves the procedures in Type 1 font data into a structure. This is a 10328NON-BACKWARD-COMPATIBLE CHANGE, but an internal one. (gxfont1.h, gstype1.c, 10329gstype2.c, gxtype1.c) 10330 10331Extends Type 1 / 2 / 4 fonts to require that they be able to enumerate the 10332set of glyphs that they define, to allow writing them out. We may propagate 10333this to all base fonts in the future. (gxfont1.h) 10334 10335Provides some utilities for devices that want to define their own 10336InputAttributes and OutputAttributes. (gdevprn.h, gxdevice.h, gdevprn.c, 10337gsdparam.c) 10338 10339Removes all of the text-display procedures that took null-terminated C 10340strings as operands. This is NON-BACKWARD-COMPATIBLE. However, since the 10341memory manager required that all such operands be allocated using 10342gs_alloc_string, the procedures were never usable with arbitrary C strings 10343anyway. (gschar.h, gschar.c) 10344 10345Renames the gx_device procedure record from std_procs to procs, in 10346anticipation of more unified support for "objects". This is a 10347NON-BACKWARD-COMPATIBLE CHANGE for a surprisingly large number of clients 10348that should have been using dev_proc and set_dev_proc. (gdevbbox.h, 10349gxdevcli.h, gxdevice.h, gdevdflt.c, gdevdgbr.c, gdevmem.c, gdevprn.c, 10350gsalphac.c, gsdevice.c, gsropc.c, gxccache.c, gxifast.c) 10351 10352Disallows setting of the RasterOp-related graphics state parameters when 10353a cache device is active. (gsrop.c) 10354 10355Changes the tracing printout of path segments to provide enough accuracy to 10356cover all the fraction bits of a 'fixed'.

It also adds RCS 10368Id lines to all the files we maintain. It also changes the Unix makefiles 10369so that they create debugging or profiling binaries in separate directories. 10370 10371<p> 10372This fileset includes an unusually large number of non-backward-compatible 10373API changes. Most of them don't affect ordinary library clients, but a few 10374do. These changes, and a few more to come, result from the next (large) 10375increment in our ongoing project to make the code completely re-entrant (no 10376non-idempotent writable globals in our own code). This necessarily involves 10377putting some things that used to be global into structures, some of which 10378must be added to some interfaces. 10379 10380<p> 10381NOTE: because of a combination of hardware problems, time pressure, and 10382belated discovery of sloppiness by the original developers of the PC 10383makefiles, none of the PC makefiles in this fileset work.

(bug probably introduced since 5.20) (unix-end.mak) 10447 - The ld_tr and CCFLAGS macros were used in the makefiles before 10448they were defined, causing problems with `make' implementations that 10449substitute macros into definitions at definition time rather than at use 10450time. (*.mak) 10451 - Recent Digital Unix versions (4.0 and later) require -std1 when 10452compiling. (make.txt) 10453 - The Unix library-only makefile had gotten out of date. 10454(ugcclib.mak) 10455 - pf2afm[.bat] were omitted from the fileset. (master/package.tcl) 10456 - The Borland makefile didn't work, because the Borland compiler 10457requires specifying the output file name (-o) before the input file name 10458(-c)! This required changing the order of every compilation command in 10459every platform-independent makefile. The win*.mak files still need work. 10460(*.mak) 10461 - None of the non-Unix makefiles specified directory names for the 10462auxiliary programs. (dvx-tail.mak, os2.mak, wctail.mak, winlib.mak) 10463 - The Windows makefiles lacked build rules for gp_ntfs and gp_win32. 10464(msvclib.mak, winlib.mak) 10465 10466Adds a new debugging switch -Z/ that prints the file name and line number on 10467all trace messages.

This allows keeping all 3 configurations active. (unix-end.mak) 10472 10473Adds GEN directories for jpeg, libpng, and zlib. (devs.mak, gs.mak, 10474jpeg.mak, lib.mak, libpng.mak, zlib.mak) 10475 10476Adds a gendev.c that will eventually replace genconf.c. (gendev.c, *.mak) 10477 10478Adds -Wcast-align to the gcc compilation switches. (unix-gcc.mak) 10479 10480Adds support for libpng 1.0.1. (libpng.mak) 10481 10482Notes the use of -R on Solaris and other SVR4 systems. (unix*.mak) 10483 10484Removes pdf_2ps.ps from the fileset. (int.mak, unixinst.mak, 10485pdf_2ps.ps[deleted]) 10486 10487Ensures that every file that is copyright, maintained, and distributed by 10488Aladdin Enterprises has a RCS Id line. In .c and .h files, these lines 10489currently are only comments, but they could be converted easily to static 10490strings later if we want to. We had to touch almost every file in the 10491fileset to do this, but we did *not* change the write dates. (*) 10492 10493Makes the build procedure auto-detect whether the installed version of gcc 10494has the 'const' code generation bug. (gs.mak, lib.mak, unix-gcc.mak) 10495 10496Removes 'makefile' as a precondition for ccf32.tr. (I can't quite figure 10497out why it was there in the first place.) (msvccom.mak) 10498 10499Replaces the -F<file> switch with a -B<buffer size> switch that forces all 10500files to use the run_string interfaces. -B- turns it off. (iminst.h, 10501imainarg.c) 10502 10503Adds a new resource to genconf.c, -replace <module>. This causes <module> 10504*not* to be included if the module with the -replace resource *is* included. 10505If two modules -replace each other, either directly or indirectly through 10506-includes, the result is undefined. (genconf.c) 10507 10508Uses -replace to implement a default roplib package.

(ps2epsi.ps) 10521 10522Changes the pdf2ps utility to use the pswrite device.

(gdevps.c) 10531 - The author of the uniprint driver sent a fix for an 10532allocation-related bug and an off-by-one bug. (gdevupd.c) 10533 - The PDF writer incorrectly converted open stroked rectangles (only 105343 sides drawn) to closed (4 sides drawn). (gxpath.h, gzpath.h, gdevpdfd.c, 10535gxpath2.c) 10536 - When banding, filling a character within the PaintProc of a 10537Pattern could produce memory access errors. (The problem was in 10538gx_forward_fill_mask, which might affect filling characters in other 10539situations as well.) (gdevnfwd.c) 10540 - The [e]pswrite driver produced incorrect line widths for stroked 10541graphics. (gdevps.c) 10542 - The [e]pswrite driver didn't invoke colorimage correctly, so 10543didn't handle Patterns right. (gdevps.c) 10544 - Vector devices didn't set the color before writing trapezoids, 10545possibly causing incorrectly colored output. (gdevvec.c) 10546 - Vector devices could give errors on Pattern fills. (gdevvec.c) 10547 - The bbox device retained a pointer to the clipping path, which, 10548since the path was embedded in the gs_state_contents, confused the garbage 10549collector, causing memory access errors. We fixed this by de-embedding the 10550path object: see below. (gsstate.c) 10551 - On some Linux systems, the X driver could get a memory access 10552error when displaying patterns. We fixed this by adding calls on XInitImage 10553in the necessary places when running X11R6. (gdevx.c) 10554 - PDF output didn't check names for unusual characters, and could 10555produce invalid output if the input included names with those characters. 10556(gdevpdfx.h, gdevpdf.c, gdevpdfm.c, gdevpdfo.c) 10557 - In the PDF writer, DEST pdfmarks with /Dest but no /Page or /View 10558didn't generate named destinations. (gdevpdfm.c) 10559 - Printer devices didn't allow . in %-formats in the output file 10560name. (gdevprn.c) 10561 - The x11cmyk driver didn't read bits back from the screen 10562correctly. (gdevxalt.c) 10563 - The pcxmono and pcxgray drivers used colored rather than 10564gray-scale palettes. (gdevpcx.c) 10565 - The PCX drivers could emit repetition counts greater than 15, 10566confusing some readers. (gdevpcx.c) 10567 10568Removes some vestiges of the obsolete draw_line driver procedure. We also 10569rename the draw_line member of the driver procedure structure as 10570obsolete_draw_line, so that any uses of it will cause compilation errors, 10571but we don't remove it from the structure, so that existing driver procedure 10572vectors will continue to compile (although the draw_line procedure will 10573never be called). (gxdevcli.h, gdevbbox.c, gdevddrw.c, gdevdflt.c) 10574 10575To repair a design error, and at the same time add flexibility needed for 10576ImageType 3: 10577 10578 - Removes the image_data and end_image driver procedures, 10579associating them with the gx_image_enum(_common)_t structure instead. 10580Clients should call gx_device_image_data and gx_device_end_image instead: we 10581set the image_data and end_image procedures in the device structures to 10582these procedures when filling in defaulted procedures. This is a 10583NON-BACKWARD-COMPATIBLE CHANGE for drivers that implement begin_image, since 10584they now have to fill the procedures into the enumerator structure. 10585(gsiparm*.h, gxdevcli.h, gxdevice.h, gxiparam.h, gdevbbox.c, gdevddrw.c, 10586gdevdflt.c, gdevnfwd.c, gsimage.c, gxclist.c, gxidata.c, gxifast.c, 10587gxiinit.c, gximage3.c, gximage4.c) 10588 10589 - Replaces the image_data driver procedure with a plane_data 10590procedure (now associated with the image enumerator, not the device) that 10591allows specifying the X offset and raster independently for each plane, and 10592(depending on the image type) may allow omitting some planes. We provide a 10593gx_device_image_plane_data procedure parallel to _image_data and _end_image 10594(see above).

This involves a change in the moveto procedure in the 10602'vector' interface. (gdevps.c) 10603 10604Changes the bbox device so that it automatically detects whether it is being 10605used as a component in a device pipeline or as a free-standing device, 10606rather than having to select this in the makefile. (lib.mak, gdevbbox.h, 10607gdevbbox.c) 10608 10609Moves the halftoning driver a bit closer to real usability. (gdevht.h, 10610gdevht.c) 10611 10612Adds some tracing to the color mapping code in the X driver. (gdevx.c) 10613 10614Implements setting the Dict and ACSDict parameters for pswrite and pdfwrite. 10615Dict is effective with the CCITTFaxEncode filter for black-and-white images; 10616otherwise, these parameters still don't do anything.

(gdevpsdf.c) 10622 10623Modifies the X driver so that it can draw multiple platform characters at a 10624time rather than one character per call. (gdevx.h, gdevx.c, gdevxxf.c) 10625 10626Takes advantage of the filter stream procedures now available in stream.c. 10627(gdevjpeg.c, gdevpdf.c, gdevpsdf.c) 10628 10629Adds a get_hardware_params procedure, similar to get_params except that it 10630reads parameters whose values depend on hardware state that may change 10631without program intervention (e.g., panel switches).

(std.h, gdebug.h, gsmisc.c) 10879 10880Adds new dlprintf, dlputc, and dlputs macros that are like 10881dprintf/dputc/dputs but also print the source file name and line number at 10882the beginning of the line if the -Z/ debugging switch is set. The if_debug* 10883macros now use dlprintf rather than dprintf; many other places also needed 10884changing. Note that if any place was overlooked, no great harm is done: 10885printout produced there simply won't include the source file and line number 10886even if -Z/ is set.

(gxhint2.c) 10914 10915Moves the 'format' information for images to the image parameter structure. 10916This entails a NON-BACKWARD-COMPATIBLE CHANGE in the begin_typed_image 10917driver procedure (which was not guaranteed stable). (gsiparam.h, 10918gxdevcli.h, gsimage.c, gxiinit.c) 10919 10920Adds an optional matrix argument to begin_typed_image, overriding the CTM in 10921the imager state if present.

This may not have any practical effect, 10936since currently Type 42 fonts never split the loca table across segments. 10937(gstype42.c) 10938 10939Adds a new interface for creating CIE CRDs that provides the parameters as 10940separate arguments. (gscrd.h, gscrd.c) 10941 10942Starts to add the ability for a device to provide one or more default CIE 10943CRDs as (read-only) device parameters. (Not ready for use yet.) (gscie.h, 10944gscrdp.h, gscie.c, gscrdp.c) 10945 10946Adds a multiple-bit-per-pixel analogue of gs_makebitmappattern, 10947gs_makepixmappattern, for use by another Aladdin project. (lib.mak, 10948gsbitmap.h, gsptype1.h, gxbitmap.h, gspcolor.c) 10949 10950Changes the API of param_begin_write_dict so that the client can request the 10951creation of an array rather than a dictionary. This is a 10952NON-BACKWARD-COMPATIBLE CHANGE for implementors (of which there are only 109532.5), but not for clients. (gsparam.h, gsparam.c) 10954 10955Adds dynamically typed data to the parameter list interface, and removes the 10956statically typed procedures. This isn't important for any standard facility 10957yet. This too is a NON-BACKWARD-COMPATIBLE CHANGE for implementors of 10958parameter lists. (gsparam.h, gsparams.h, gsparam.c, gsparams.c) 10959 10960Adds a new platform-specific API for thread creation and synchronization, 10961and a memory manager "wrapper" that monitor-locks each call. No code 10962normally included in this fileset uses any of this machinery as yet. (gp.h, 10963gpsync.h, gxsync.h, gsmemlok.h, gsmemlok.c, gxsync.c) 10964 10965Splits off (PatternType 1) Pattern filling into a separate file, since the 10966file was getting too big; refactors the filling code to use procedures 10967rather than macros. (gxp1fill.h, gspcolor.c, gxp1fill.c) 10968 10969Makes a few more writable statics const. (gscie.h, gscscie.c, gsdll.c, 10970gsmemory.c, gsmisc.c, gstype1.c, gstype2.c, gxclpath.c) 10971 10972Adds a compile-time option, SYSTEM_CONSTANTS_ARE_WRITABLE, to choose whether 10973the system configuration values (buildtime, copyright, product, revision, 10974revisiondate, serialnumber) are const or not. By default they are now 10975const: THIS IS A NON-BACKWARD-COMPATIBLE CHANGE (affecting only one user). 10976(lib.mak, openvms.mak, os2.mak, unix-end.mak, wctail.mak, winlib.mak, 10977gscdefs.h, gscdef.c) 10978 10979Removes the dependence of std.h on PROGRAM_NAME. (std.h, gsdll.c, gsmisc.c, 10980gscdef.c) 10981 10982Adds a new member of the color space type structure, the size of the 10983smallest color space structure that will hold a color space of the given 10984type. Also removes the obsolete _ds modifier. (gscspace.h, gxcspace.h, 10985gscdevn.c, gscie.c, gscolor.c, gscolor1.c, gscolor2.c, gscpixel.c, 10986gscsepr.c, gspcolor.c, gxiinit.c) 10987 10988Removes set/currentrenderalgorithm, since they are useless for the purpose 10989for which they were intended. (gsrop.h, gsropt.h, gdevmrop.c, gsrop.c) 10990 10991Splits off gscspace.c from gscolor.c, and gscscie.c from gscie.c. (gscie.c, 10992gscolor.c, gscscie.c, gscspace.c) 10993 10994Adds constructor and accessor procedures for color spaces.

(gscie.h, gscie.c) 11001 11002Changes gs_malloc_limit from a static to a member of the allocator 11003structure. This is a NON-BACKWARD-COMPATIBLE CHANGE for clients that 11004declared this variable as an extern. (gsmalloc.h, gsmemory.c) 11005 11006In order to eliminate some statics, changes the static color space accessors 11007(gs_color_space_Device*) so they require a const gx_imager_state as 11008parameter, and changes their names as well to avoid confusion. This is a 11009NON-BACKWARD-COMPATIBLE CHANGE not only in these accessors, but also in 11010gs_image_t_init_{gray,color}. This is very unfortunate, but we see no way 11011to avoid it. (gscspace.h, gsiparam.h, gxistate.h, gscolor1.c, gscscie.c, 11012gscspace.c, gsimage.c, gspcolor.c, gsstate.c, gxclread.c, gxiinit.c, 11013gximage2.c, gximage3.c, gximage4.c) 11014 11015Unifies the handling of const for the IODevice table. (gscdefs.h, 11016gxiodev.h, gconf.c, gsiodev.c) 11017 11018Changes the register_root memory manager call so that a NULL as the pointer 11019to the root structure asks the memory manager to allocate the root structure 11020itself. This is a NON-BACKWARD-COMPATIBLE CHANGE for implementors of the 11021memory manager API (of which there are only 3). (gsmemory.h, gsstruct.h, 11022gsalloc.c, gsmemory.c) 11023 11024Adds a new GC structure type, suffix_add0_local, which is a more efficient 11025form of suffix_add0 that can be used when the supertype is defined in the 11026same file as the subtype. (gsbitmap.h, gscie.h, gsshade.h, gsstruct.h) 11027 11028Uses the new package replacement facility in the makefile to make RasterOp 11029optional without tinkering with statics at runtime.

(gdevmrop.h, gsrop.h, gdevmrop.c, gsrop.c, 11034gxiinit.c) 11035 11036Rewrites bits_fill_rectangle to get rid of nearly all the macros. 11037(gxbitops.h, gsbitops.c) 11038 11039Removes the obsolete _ds from gs_log_error.

The old names are still recognized 11464for backward compatibility. (gs.mak, int.mak, *.mak) 11465 11466Removes support for building with DCL under VMS. Building under VMS now 11467requires some version of make, preferably GNU make.

THIS IS A NON-BACKWARD-COMPATIBLE CHANGE: 11486rather than editing the *head.mak files, users should now edit the unix*.mak 11487or dvx*.mak files (which they previously were instructed NOT to do). Aside 11488from this, we think the change won't actually affect anyone, since most Unix 11489make programs (include GNU make) do recognize this directive.

(gp_dosfb.c, gp_vms.c) 11701 11702Adds a platform-specific gp_getenv call, to allow the Windows implementation 11703to consult the Registry. (gp.h, gpgetenv.h, gp_getnv.c, gp_wgetv.c, *.mak, 11704gp_win32.c) 11705 11706Separates out the declaration of popen and pclose, which may be declared 11707correctly in stdio.h, incorrectly in stdio.h, or not at all, depending on 11708the platform. (lib.mak, unixtail.mak, pipe_.h, gdevpipe.c, gp_os2.c, 11709gp_os9.c, gp_unix.c) 11710 11711Tweaks the platform-workaround header file conditionals a little more. 11712(malloc_.h, memory_.h). 11713 11714Makes the Windows DLL check the GS_DLL environment/registry variable for the 11715location of the DLL.

(gs_fonts.ps) 11724 - Type 2 fonts didn't always have a PaintType entry. (gs_cff.ps) 11725 - CIDFontType 0 fonts were broken, probably because of a recently 11726added validity test in the C code. (gs_cidfn.ps) 11727 - Font types without an Encoding caused an error (in .completefont). 11728(gs_fonts.ps) 11729 - composefont required the elements of the font array to be actual 11730fonts, rather than allowing font names. (gs_cidfn.ps) 11731 - composefont required that all elements of the font array have 11732CIDSystemInfo dictionaries. (Adobe has said that their interpreters don't 11733check for this in some cases, but it's a bug. Unfortunately, by now it's an 11734established one.)

(gs_fonts.ps) 11737 11738</pre><h3><a name="V5.20_Interpreter"></a>Interpreter</h3><pre> 11739 11740Fixes bugs: 11741 - A Type 2 font that provided fewer CharStrings than charset 11742elements caused an error. (gs_cff.ps) 11743 - If a context was joined before it terminated, its stack was never 11744copied to the joining context. (zcontext.c) 11745 - Freeing a context didn't free most of its substructures. 11746(icontext.h, istack.h, icontext.c, interp.c, istack.c, zcontext.c) 11747 - save and restore didn't save and restore the user parameters. 11748(gs_lev2.ps, zvmem2.c) 11749 - %stdin and %stdout weren't defined per-context. (files.h, 11750icontext.h, icontext.c, ziodev.c) 11751 - Switching contexts didn't clean up the stacks. (The current way 11752we do this is very inefficient: we should use a special null for filling the 11753untouched area, so we can use it to detect the high water mark.) 11754(icontext.c) 11755 - A cast from const to non-const was missing. (zdpnext.c) 11756 - User parameters weren't managed per-context. (The current way we 11757do this is inefficient.) (gs_dps.ps, gs_init.ps, gs_lev2.ps, isave.h, 11758icontext.c, iinit.c, isave.c, zcontext.c, zusparam.c) 11759 - Some operand checks weren't wrapped in do { ... } while(0), 11760possibly leading to incorrect parsing of 'if's. (opcheck.h) 11761 - If a context terminated with unmatched saves, the restores weren't 11762executed. (isave.h, isave.c, zcontext.c) 11763 - If two or more contexts shared the same global VM, the outermost 11764restore (which in this case saves only local VM) checked for invalidrestore 11765incorrectly. (isave.c) 11766 - resourceforall didn't remove its own temporary values from the 11767operand stack when calling the procedure.

(gs_res.ps) 11770 - If a context had unmatched saves, other contexts sharing the same 11771local VM weren't blocked from running. (zcontext.c) 11772 - The NeXT compositing operations (Copy, etc.) weren't defined in 11773systemdict. (gs_dpnxt.ps) 11774 - In the case of a stack overflow, some garbage could get left on 11775the stack. (istack.c) 11776 - Stack overflow was reported prematurely -- typically when the 11777stack depth had reached half the specified limit. (istack.c) 11778 - Freed ref arrays weren't filled with nulls, which could confuse 11779the garbage collector later. (ialloc.c) 11780 - Certain stack overflow conditions could put a stack into an 11781anomalous state that confused the garbage collector. (istack.c) 11782 - The maximum stack size could not be set to a value smaller than 11783the current allocated space, but the minimum value should be the number of 11784entries actually in use. (istack.c) 11785 - If .buildfont* had to add any elements to the font dictionary, a 11786temporary pointer to the Encoding, FDepVector, or sfnts could become 11787invalid, causing crashes or confusion. (zfont0.c, zfont2.c, zfont42.c) 11788 11789Changes exit, stop, and .stop so that if there is no matching dynamically 11790enclosing context (loop or stopped), the effect is a quit, like the Adobe 11791interpreters, and not an invalidexit.

(gs_lev2.ps, igstate.h, zcsdevn.c) 11811 11812Adds support for Type 32 fonts. (gs_cidfn.ps, gs_init.ps, gs_typ32.ps, 11813zchar32.c, zfont32.c) 11814 11815Adds debugging printout to the CFF loader. (gs_cff.ps) 11816 11817Removes support for _ds pointers referencing the stacks, since we no longer 11818support 16-bit implementations. (iref.h, istack.h, interp.c, ireclaim.c, 11819istack.c) 11820 11821Removes all #ifdef DPNEXT conditionalization. (We had intended to use this 11822to delimit blocks of code to be released with the GPL, but we're now 11823planning to release a much larger number of files.) (igstate.h, interp.h, 11824istruct.h, interp.c, zgstate.c) 11825 11826Allows user parameters to be implemented partly in PostScript code, since 11827this is required for some LanguageLevel 3 features (currently only 11828IdiomRecognition). (gs_lev2.ps) 11829 11830Removes most of the references to a global process scheduler. Completing 11831this will require passing an interpreter state structure to all operators in 11832place of the operand stack pointer, which we aren't prepared to contemplate 11833yet. (zcontext.c) 11834 11835Adds tracing for context operations, -Z' and -Z". (zcontext.c) 11836 11837Changes def so that it doesn't have a special exception for storing 11838references to local objects into systemdict or its subsidiary dictionaries 11839during initialization: such stores now must use .forceput (or .forcedef, 11840defined in gs_init.ps using .forceput); changes .forceput to allow storing a 11841local reference into any global dictionary, not only systemdict, if the save 11842level is 0. (gs_dps1.ps, gs_init.ps, gs_lev2.ps, gs_pdfwr.ps, gs_res.ps, 11843gs_statd.ps, zdict.c) 11844 11845Moves all of the initialization of internaldict to PostScript code. 11846(gs_init.ps, iinit.c, zcontrol.c) 11847 11848Moves the JobName user parameter from C to PostScript code. (gs_lev2.ps, 11849zusparam.c) 11850 11851Adds to every dictionary a pointer to the allocator that created it. This 11852allows us to create and grow dictionaries without having to reference any 11853global variables. (idict.h, idict.c, iinit.c) 11854 11855Implements the localfork operator, which creates contexts with private local 11856VM.

(gs_dps.ps, zdps.c) 11871 11872Adds begin_typed_image to internal device procedure vectors. (zupath.c) 11873 11874Increases the maximum stack sizes to match the Adobe implementation more 11875closely. (gs_init.ps) 11876 11877Adds a file_is_invalid macro to work around a bug in the Borland 5.0 11878compiler. (files.h, ziodev.c, zvmem.c) 11879 11880Changes the character cache to be allocated in the C heap rather than global 11881VM. This is required because cache chunks are now allocated from the same 11882allocator as the cache. (zfont.c) 11883 11884Implements sizeimage and readimage, including a new .getbitsrect operator. 11885(gs_dpnxt.ps, gs_init.ps, zdevice.c, zdpnext.c) 11886 11887Resets the maximum stack sizes earlier in initialization. (gs_init.ps) 11888 11889Tweaks the default CRD slightly (syntactically, not the content). 11890(gs_lev2.ps) 11891 11892Adds support for PatternTypes other than 1. (gs_init.ps, gs_lev2.ps, 11893gs_res.ps, zpcolor.c) 11894 11895Adds a pointer to the C heap allocator to the gs_main_instance structure, 11896working towards the goal of removing all references to gs_memory_default. 11897(iminst.h) 11898 11899Removes all remaining uses of gs_malloc and gs_free from the interpreter. 11900(igc.h, igc.c, imain.c, zfdctd.c, zfdcte.c) 11901 11902Adds an explicit #include for all remaining uses of gs_memory_default in the 11903interpreter. (zfdctd.c, zfdcte.c, zvmem.c) 11904 11905Adds a map_color_rgb_alpha driver procedure, complementing 11906map_rgb_alpha_color. (zupath.c) 11907 11908Removes the obsolete writeppmfile operator. (zwppm.c[deleted]) 11909 11910Updates the implementation of the image operators to match the change from 11911HasAlpha to Alpha in the image definition structure. (iimage.h, zcolor1.c, 11912zimage.c) 11913 11914Reimplements upath in C code, since UnpaintedPath requires it. (zupath.c) 11915 11916Updates interpreter code for the change in the GC interface.

This 11977required changing the implementation of seac so that it does the base 11978character first, rather than the accent.

(gspath.h, gzpath.h, gspath1.c, gxpath2.c) 12063 12064Changes the garbage collector interface so that all procedures are passed 12065through a structure rather than being referenced as externs. This allows 12066programs other than the GC itself to enumerate and relocate pointers, and 12067also removes all static dependencies on the GC from the library. This 12068involves a NON-BACKWARD-COMPATIBLE CHANGE to the argument list of enum_ptrs 12069procedures, and to the implementation of both enum_ptrs and reloc_ptrs.

(gschar.h, 13006gschar.c) 13007 - The check for whether characters can be cached didn't consider 13008PaintType values other than 0 and 2. (gschar.c) 13009 - The bounding box device didn't handle PageCount properly. 13010(gdevbbox.c) 13011 - Uncached fonts with a next_char procedure didn't set the glyph 13012properly. (gschar.c) 13013 - Parallelograms with ax < bx, ay < by, and the 'a' edge to the 13014right of the 'b' edge weren't filled, causing pixels to be omitted from some 13015highly skewed images. (gdevddrw.c) 13016 - 12-bit-per-pixel images in portrait orientation filled each scan 13017line with the value of the last pixel -- i.e., didn't work. (gximage4.c) 13018 - The path representation of a clipping path could include some 13019inappropriate, leftover path segments. (gxcpath.c) 13020 - The angle for the miter check was computed in device space rather 13021than in user space. (gxstroke.c) 13022 - TrueType fonts were lumpy, and the accents of accented characters 13023were placed incorrectly. (gstype42.c) 13024 - Some macros used for generating device prototypes didn't 13025parenthesize all uses of their parameters, causing possible errors if the 13026parameters were expressions rather than numeric constants. (gdevprn.h) 13027 - When banding, strip halftones (typically produced by 13028AccurateScreens) sometimes didn't have the correct phase. (gxbitmap.h, 13029gxclread.c) 13030 - A minor change was required for correct compilation with Microsoft 13031VC++. (memory_.h) 13032 - Under certain conditions, character shapes could get wildly 13033distorted by hints. (bug introduced in 5.01) (gxhint3.c) 13034 13035For greater Adobe compatibility: 13036 - Changes reversepath so that the implicit line created by closepath 13037is not considered a "segment". (gxpath2.c) 13038 13039Fixes some minor compilation warnings not affecting code functionality. 13040(gstype1.c) 13041 13042Changes the font and scaled-font caches so that if the font has a UID 13043(UniqueID or XUID), the UID and FontType are both considered part of the 13044key, and we don't cache fonts with non-zero PaintType. (The Red Book says 13045that changing anything except the Encoding should also change or remove the 13046UID, but some files don't do this. The current fix is probably not 13047sufficient, but it is a step in the right direction.) (gxfcache.h, 13048gxccache.c, gxccman.c) 13049 13050Splits off the definitions of font_type and fbit_type into a separate file, 13051since gxfcache.h now needs font_type. (gxfcache.h, gxfont.h, gxftype.h) 13052 13053Makes the Flex feature in Type 1 fonts conform to the published 13054specification, rather than always producing curves. The comment in the code 13055(and in the NEWS entry for release 2.6) says that this breaks some very old 13056Adobe fonts: if this turns out to be a problem, we'll figure out a test that 13057will do the right thing for these fonts. (gstype1.c) 13058 13059Provides 'double' versions of some API functions to accommodate the 13060increased use of doubles in the interpreter. (gschar.h, gschar.c) 13061 13062Adds a compile-time option to force the use of strip halftones, for 13063debugging. (gshtscr.c) 13064 13065Changes the hint snapping algorithm in the Type 1 rasterizer so that it will 13066only change a stem width by a maximum of 1/2 pixel rather than 1 pixel. 13067This appears to help with dropouts at certain sizes. (gxhint2.c) 13068 13069Makes a few changes for clean compilation on BeOS. (stdpre.h, stat_.h, 13070gxcpath.c) 13071 13072</pre> 13073 13074<hr> 13075 13076<h2><a name="Version5.01"></a>Version 5.01 (6/22/97)</h2> 13077 13078<p> 13079This fixes a few bugs reported in the 5.0 release.

(README) 13086 - The comment on flip4x12 had a typo. (gsflip.c) 13087 - The algorithm comments for adjusted_y_spans_pixel weren't precise 13088enough. (gxfill.c) 13089 - The usage message printed by the ps2pdf script didn't indicate 13090that one can now insert options before the input file name. (ps2pdf) 13091 - The file searching documentation didn't indicate that paths 13092beginning with ./ or ../ are considered "explicit" and not subject to 13093searching. (use.txt) 13094 - The description of SEARCH_HERE_FIRST in the per-platform makefiles 13095indicated that it only applied to initialization files, not to files 13096specified on the command line as well. (*.mak) 13097 - There were still some references to 16-bit implementations. 13098(install.txt) 13099 13100Clarifies that -dNODISPLAY also suppresses output to other devices. 13101(use.txt) 13102 13103Adds the e-mail address for reporting problems to the bug report form, and 13104also a space to report makefile changes. (bug-form.txt) 13105 13106Adds a note under -g indicating that it fixes the media size. (use.txt) 13107 13108Adds an explanation of why Ghostscript can't use the system libraries for 13109the JPEG package. (make.txt) 13110 13111Notes that ps2ai doesn't work properly with Adobe's Helvetica-Oblique font, 13112and other fonts whose original FontMatrix involves skewing or rotation. 13113(psfiles.txt) 13114 13115Updates the uniprint documentation slightly. (devices.txt) 13116 13117Notes that the new lj5 drivers do not work with the LJ5L. (devs.mak) 13118 13119Modifies the Aladdin Free Public License slightly to make it clearer that 13120the exception for freely redistributable CD-ROMs only applies if the CD-ROM 13121is being distributed by itself, not with anything else commercial. (This 13122has always been the case, but the previous wording wasn't clear enough.) 13123(PUBLIC) 13124 13125Notes that gcc with -O still has code generation problems on H-P RISC 13126machines. (make.txt) 13127 13128Adds a pointer to Martin Lottermoser's hpdj driver. (new-user.txt) 13129 13130Enhances and reorganizes the documentation for building Ghostscript, in 13131response to user feedback. (make.txt, install.txt) 13132 13133Adds a description of the EPSF recognition feature. (language.txt) 13134 13135</pre><h3><a name="V5.01_Procedures"></a>Procedures</h3><pre> 13136 13137Fixes bugs: 13138 - string__h was misspelled string_h in one place. (lib.mak) 13139 - gs_dps.ps wasn't installed by "make install". (unix-end.mak) 13140 - ccgs (used with non-ANSI C compilers) didn't do the right thing 13141with -DPNG_USE_CONST. (ccgs) 13142 13143Adds support for version 96 of libpng, and updates all the makefiles to 13144reference it. (libpng.mak, *.mak) 13145 13146Updates the MSVC makefiles to get rid of some warning messages and provide a 13147way to specify a library path for the final link. (msvc*.mak) 13148 13149</pre><h3><a name="V5.01_Utilities"></a>Utilities</h3><pre> 13150 13151Fixes bugs: 13152 - The usage message for the gslp utility had a minor typo. 13153(gslp.ps) 13154 - The "line printer" utility didn't expand tabs properly when 13155producing PostScript output. (gslp.ps) 13156 - The gslp utility didn't automatically include the date. (gslp) 13157 - The line printer scripts didn't pass the script name to the 13158utility program, so the usage message didn't use the correct name. (gsbj*, 13159gsdj*, gslj*, gslp*, lp*) 13160 13161Modifies the gslp utility so that invoking it with no arguments prints the 13162usage message. (gslp.ps) 13163 13164Adds the ability to specify the number of bits per component to the 13165CMYK-viewing utility. (viewcmyk.ps) 13166 13167Changes the ps2pdf script so that on Windows NT, as on Unix, it allows 13168omitting the output file name, automatically replacing the extension of the 13169input file with .pdf. (ps2pdf.bat) 13170 13171</pre><h3><a name="V5.01_Drivers"></a>Drivers</h3><pre> 13172 13173Fixes bugs: 13174 - Some compilers didn't accept a #define with the macro name on the 13175next line. (gdevpx.c) 13176 - The procedure dash_pattern_eq was defined in two places. 13177(gdevpdf.c) 13178 - The uniprint driver sometimes dropped some output or got confused, 13179because of a misunderstanding about how to update device procedure vectors 13180properly. (gdevupd.c) 13181 - The PostScript and EPS writers produced binary output for images, 13182which generally can't be sent to PostScript printers. (gdevpsdf.h, 13183gdevpdf.c, gdevps.c) 13184 - The EPS writer put a %%EOF at the end of the file, which might 13185cause problems for some spoolers if the file is embedded in another. 13186(gdevps.c) 13187 13188Changes the implementation of printer drivers so that they flush the output 13189stream after each page. We aren't absolutely sure that this is a good idea, 13190but it prevents certain anomalous behavior where the last page isn't ejected 13191properly. (gdevprn.c) 13192 13193Implements a long-delayed update to the mgr drivers, to restore the color 13194mapping to an older one. (gdevmgr.h, gdevmgr.c) 13195 13196Updates the uniprint driver with a number of changes from its author. 13197(gdevupd.c) 13198 13199</pre><h3><a name="V5.01_Platforms"></a>Platforms</h3><pre> 13200 13201Adds the JPEG, Postscript, and PCL XL drivers, which are included on all 13202other platforms, to the MS Windows platforms. (bcwin32.mak, msvc4.mak, 13203msvc5.mak, watcw32.mak) 13204 13205</pre><h3><a name="V5.01_Interpreter"></a>Interpreter</h3><pre> 13206 13207Fixes bugs: 13208 - composefont defined the resource with the font name and font 13209directory interchanged. (gs_cmap.ps) 13210 - With dFIXEDMEDIA, documents requesting other sizes caused an error 13211instead of clipping the page. (gs_init.ps) 13212 - PageSize Policy = 7 wasn't implemented. (However, the current 13213implementation is wrong.) (gs_setpd.ps, zmedia2.c) 13214 - FontType resource 42 wasn't defined even if Type 42 fonts were 13215supported; similarly for FontType 9, 10, and 11 for CIDFonts. (gs_cidfn.ps, 13216gs_res.ps) 13217 - The error handling machinery would break if the name /errordict 13218was redefined. (gs_init.ps) 13219 - Level 1 systems got an /undefined in .doneshowpage. (zdevice.c, 13220zdevice2.c) 13221 - Because of an initialization order problem, copy didn't work on 13222gstates. (zgeneric.c) 13223 13224Adds a naive implementation of findcolorrendering. (gs_lev2.ps, gs_res.ps) 13225 13226Removes the 'stopped' around run_string[_begin/continue/end] so that, as in 132274.03, errors print a hex dump and exit with a non-zero code instead of 13228printing a readable message and continuing. (We aren't sure that this 13229change didn't undo the fix in 5.0 regarding calling startjob from 13230run_string.) (gs_init.ps) 13231 13232</pre><h3><a name="V5.01_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre> 13233 13234Fixes bugs: 13235 - stdin redirection failed for PDF files even if the new stdin was 13236seekable. This was fixed in 4.02, but the fix stopped working with the 13237introduction of .runexec. (pdf_main.ps) 13238 13239Makes the cross-reference reader accept a startxref value that points at the 13240EOL before the xref line. The Adobe documentation doesn't allow this, but 13241some real files are this way. (pdf_main.ps) 13242 13243</pre><h3><a name="V5.01_Library"></a>Library</h3><pre> 13244 13245Fixes bugs: 13246 - The bounding box of a completely empty path was reported as 13247garbage. (gxpath2.c) 13248 - Stroking a path with more than one segment didn't produce correct 13249output when anti-aliasing was used. (gspaint.c) 13250 - The alpha-buffer device returned an incorrect clipping box, 13251causing output to be discarded. (gdevabuf.c) 13252 - gx_forward_get_clipping_box passed the wrong device to the target 13253procedure, producing incorrect results. (gdevnfwd.c) 13254 - The sin/cos procedure did some unnecessary computations 13255(performance bug only). (gsmisc.c) 13256 - The procedure for adjusting the ends of curves to match the 13257tangents did some unnecessary computations (performance bug only). 13258(gxpcopy.c) 13259 - RAM-based banding always gave an invalidfileaccess error, due to a 13260typo in memfile_fopen. (gxclmem.c) 13261 - The algorithms for deciding whether a line is thin still weren't 13262correct. (gxstroke.c) 13263 - The fill adjustment values for the any-part-of-pixel case (adjust 13264= 0.5) were (0.5-epsilon, 0.5+epsilon), which colored inappropriate 13265additional pixels if the higher coordinate was integral. With considerable 13266trepidation, we have changed this to (0.5-epsilon,0.5), which does the right 13267thing in every case we can think of. (gxfill.c) 13268 - When banding, paths were clipped to only 0.5 pixel outside their 13269bounding box, which may be slightly too conservative; 1 pixel is safer. 13270(gxclpath.c) 13271 - The algorithm for testing whether an adjusted Y value spanned a 13272pixel center was incorrect, causing some pixels to get colored incorrectly. 13273(gxfill.c) 13274 - 24-bit devices could cause a memory fault, by accessing a pointer 13275just beyond the end of the line pointer array. (gdevm24.c) 13276 - Astonishingly enough, the determination of which hints were 13277applicable to a given segment of a Type 1 character was wrong in several 13278different places. Fixing this in a way that correctly handled all allowed 13279permutations of the coordinate system was not simple. (gxfont1.h, 13280gxhint1.c, gxhint3.c) 13281 - The debugging printout macros didn't include the syntactic hack to 13282prevent an 'else' from begin assigned to the wrong 'if'. (gdebug.h) 13283 - The bbox device was accidentally limited to 130 x 130 pixels (not 13284130" x 130"). (bug introduced in 5.0) (gdevbbox.c) 13285 - The bbox device didn't recognize PageBoundingBox in put_params, 13286causing a possible /undefined error on [g]restore. (gdevbbox.c) 13287 - setlinewidth didn't take the absolute value of its operand. 13288(zgstate.c) 13289 - Some code formatting was slightly off. (gximage5.c) 13290 - Some extra pixels were written for Interpolated images, but they 13291were immediately overwritten, so the output was correct. (gximage5.c) 13292 13293Changes the data flipping API from a macro to a procedure, adds a return 13294value, and makes the individual flipping procedures private. (gsflip.h, 13295gsflip.c) 13296 13297Adds (under an #ifdef FUTURE) code to allow passing multi-plane images 13298through the band list. (gxclpath.h, gxclimag.c, gxclread.c) 13299 13300Adds (under an #ifdef FUTURE) code to allow passing interpolated images 13301through the band list. NOTE: interpolated images will appear slightly 13302different than without banding, because the part of the image intersecting 13303each band will be scaled slightly differently in the (device) Y direction. 13304(gxclpath.h, gxclimag.c, gxclread.c, gximage.c) 13305 13306Changes Type 1 hinting so that when it moves points on a curve, it does so 13307by properly scaling the curve in the given direction.

(current.txt) 13330 - The URL for the uniprint driver home page was incorrect. 13331(devices.txt) 13332 - The makefiles referred to sfilefd.c, which is now named sfxfd.c. 13333(gs.mak, *.mak) 13334 13335Adds a VMS help file. (gs-vms.hlp) 13336 13337Removes documentation for Digital Unix (OSF/1) 1.2 and 1.3, which are now 13338long obsolete, and updates the documentation for current versions. 13339(make.txt) 13340 13341Notes that there may be a problem with libpng version 0.95. (libpng.mak) 13342 13343Adds some specific documentation for the JPEG drivers.

(msvccom.mak) 13358 - The Borland makefile wasn't even close to working; fixing it 13359required moving the compilation rule for genarch.exe into the 13360compiler-specific makefiles. (bcwin32.mak, msvccom.mak, watcw32.mak, 13361wincom.mak) 13362 - There were some (harmless) undefined macro references in the MSVC 13363makefile.

This fix should have 13387been in the 4.81 fileset, but was left out due to operator error. 13388(gs_dps1.ps) 13389 - Some compilers complained about macro argument replacement within 13390a string literal. (isave.c) 13391 -dSAFER didn't allow opening the %stdxxx files, which caused the 13392combination of -dSAFER and -dNOBIND to cause an infinite error. 13393(gs_init.ps) 13394 - If C code used run_string to execute a startjob, an error 13395occurred. (gs_init.ps) 13396 13397</pre><h3><a name="V5.0_Library"></a>Library</h3><pre> 13398 13399Fixes bugs: 13400 - Some compilers complained about macro argument replacement within 13401a string literal. (gxclbits.c, gdevpdfi.c) 13402 - At certain resolutions, a 1-pixel line of the wrong color could 13403appear at one edge of landscape-oriented monobit images. (This is the 4th 13404or 5th time we have "fixed" this one infuriatingly fragile piece of code.) 13405(gxfixed.h, gximage1.c) 13406 - The optimized code for landscape monobit images overlooked the 13407possibility of partial images, causing parts of images to be translated and 13408possibly clipped. (Yes, it's that same fragile piece of code.) 13409(gximage1.c) 13410 - The bounding box device allowed resetting its resolution, which 13411could cause limitchecks from coordinate overflow. Our fix is to initialize 13412the device to a very high resolution (4000 dpi), which reduces the maximum 13413page size it can handle to about 130" on a side. (gdevbbox.c) 13414 - The bounding box device wasn't identified as a page device. 13415(gdevbbox.c) 13416 - The bounding box device used alone disregarded changes in page 13417size. (gdevbbox.c) 13418 - One old compiler didn't allow a structure member name to be the 13419same as a typedef name. (gximage.h, gximage.c, gximage4.c) 13420 - The height and band intersection computations for banded images 13421still weren't right, leading to inconsistencies in the band list and errors 13422in the output (typically, thin horizontal white stripes at band boundaries). 13423(gxclimag.c) 13424 13425Adds an extensive memory dump facility to the standard allocator. 13426Eventually this should be moved into a separate file, but it would be too 13427disruptive to do this just before a release.
