This is the first release in the new stable series of Ghostscript. In addition to many bug fixes it contains numerous new features. Most obvious will be improved font handling and rasterization, and better support for PDF 1.4 and 1.5 documents.
New features since the last stable release:
Topological grid fitting, an original method developed for Ghostscript by Dr. Igor V. Melichev, improves the rendering of True Type fonts at small resolutions. See the documentation for GridFitTT for information on this feature.
The PDF writer now implements PDF 1.4 encryption. See the encryption parameter documentation for more information.
A new rendering method for shadings, developed for Ghostscript by Dr. Igor V. Melichev, improves the quality and performance of rasterization on continuous tone devices. The new method allows hardware or software acceleration with help of customizable routines for filling areas with a linearly varying color. functions.
Better support for running Ghostscript in "Job Server" mode as a daemon to continually accept and convert a series of independent files.
Also new is the Rinkj deivce, an experimental new driver for some inkjet printers using ETS screening and color profiles to achieve very high quality output for tuned output. See the Rinkj section for more information.
We now support PDF 1.5 files, including the new compression and encryption modes.
We have beta support for JPEG 2000 compressed images, using the JasPer compression library. In this release this support is only enabled as in the default autoconf (POSIX) and MSVC builds.
This release also has major internal improvements toward thread safety, although we have not yet reached this goal. Nevertheless Ghostscript should be more robust when used as a library, and these changes were an important precursor to complete virtualization.
The following bug numbers were open at the time of this release:
405501, 430175, 446344, 458780, 463688, 465936, 487953, 493348, 526099, 526491, 530011, 535366, 535932, 578865, 592160, 603934, 610478, 614298, 626295, 674418, 677324, 685335, 686747, 686750, 686816, 686819, 686824, 686841, 686842, 686843, 686853, 686865, 686867, 686919, 686980, 686996, 687011, 687012, 687013, 687039, 687059, 687063, 687084, 687086, 687095, 687105, 687108, 687110, 687122, 687125, 687146, 687168, 687174, 687193, 687196, 687203, 687219, 687221, 687229, 687231, 687243, 687251, 687257, 687259, 687271, 687280, 687295, 687297, 687298, 687303, 687314, 687316, 687324, 687327, 687341, 687342, 687345, 687346, 687360, 687373, 687375, 687394, 687397, 687399, 687401, 687410, 687414, 687434, 687435, 687445, 687460, 687468, 687473, 687474, 687475, 687480, 687484, 687485, 687492, 687497, 687498, 687514, 687518, 687520, 687523, 687525, 687529, 687531, 687535, 687536, 687537, 687539, 687541, 687545, 687551, 687558, 687559, 687560, 687561, 687583, 687593, 687595, 687600, 687608, 687611, 687621, 687622, 687628, 687630, 687633, 687642, 687643, 687644, 687650, 687654, 687657, 687661, 687663, 687666, 687669, 687674, 687676, 687677, 687678, 687679, 687680, 687682, 687684, 687686, 687694, 687695, 687696, 687697, 687702, 687707, 687712, 687715, 687717, 687721, 687727, 687728, 687729, 687731, 687735, 687738, 687754, 687756, 687769, 687772, 687775, 687778, 687780, 687782, 687783, 687786, 687791, 687793, 687795, 687796, 687800, 687802, 687803, 687805, 687806, 687808, 687809, 687813, 687814, 687815, 687816, 687820, 687822, 687823, 687825, 687826, 687827, 687828, 687830, 687831, 687832, 687834, 687835, 687836, 687837, 687838, 687840, 687842, 687843, 687844, 687845, 687846, 687847, 687848, 687849.

Update version and date for the 8.50 release. Also some additions to the release notes.[doc/News.htm 1.158, lib/gs_init.ps 1.115, src/gscdef.c 1.51, src/version.mak 1.79]
Disable JPXDecode support in the default MacOS Codewarrior build, pending resolution of some functional issues. The autoconf gcc build can be used as a workaround.[src/macos-mcp.mak 1.32]
Correct an ambiguous '#if DEBUG' to an '#ifdef DEBUG'. Part of the fix for bug 687830.[src/vdtrace.c 1.10]
Additional clean up for the MacOS CodeWarrior build. Adds a dependency on gconfigd.h so it gets built when the project file is generated, and include a search path for the jasper library headers.[src/macgenmcpxml.sh 1.12, src/macos-mcp.mak 1.31]
Update the MacOS test framework to current code.[src/dmmain.c 1.5, src/dmmain.r 1.2]
Use #ifdef DEBUG instead of the ambiguous #if DEBUG.[src/gp_macio.c 1.37]
Add a missing dependency on the DeviceN code to the tiffsep device.[src/devs.mak 1.120]
Modify the MacOS polling implementation to use the new libctx accessor for the callbacks.[src/gp_macpoll.c 1.3]
Update the jbig2 makefile for the latest release. We now require jbig2dec 0.7 if you want to compile in the jbig2dec source instead of linking to the shared library.[src/jbig2.mak 1.9]
Delaying changes for assertions and gzspotan.c till after 8.50 release.[src/fapi_ft.c 1.14, src/gdevddrw.c 1.27, src/gdevpdfc.c 1.51, src/gdevpsf1.c 1.20, src/gdevpsft.c 1.35, src/gendev.c 1.7, src/gserror.h 1.9, src/gsfcmap.c 1.27, src/gsfunc0.c 1.23, src/gslibctx.c 1.7, src/gsmisc.c 1.22, src/gxccman.c 1.30, src/gxcht.c 1.15, src/gxdhtserial.c 1.7, src/gxfdrop.c 1.16, src/gxpflat.c 1.44, src/gxshade1.c 1.35, src/gxshade6.c 1.86, src/gzspotan.c 1.12, src/siinterp.c 1.7, src/write_t1.c 1.5, src/write_t2.c 1.7]
Mention the need to run autogen.sh to generate the configure script when building from CVS.[doc/Make.htm 1.83]
MacOS platform build cleanup. DETAILS: Since the libctx changes, stdio hasn't been directly available. Therefore we no longer support '-' as a special filename in (the obsolete) gp_open_printer(). We change an fprintf(stderr,...) to an eprintf() which is more correct in any case. This change also removes the fprintf() and fputs() implementations in the MacOS build. Metrowerks CW libc has for some time provided implementations, but they're even less needed now that we're being a proper library.[src/gp_macio.c 1.36]

Convert gs_malloc() calls in the MacOS gp_* code to unwrapped libc malloc() now that gs_malloc() requires a memory pointer, which is not available. Partial fix for bug 687830. DETAILS: Only the call in getenv() is active; the one in gp_init() is not used. This may have been what the earlier libctx patch was trying to do when it touched gp_macio.c, changing the function call, but not the arguments, and breaking the[src/gp_mac.c 1.17, src/gp_macio.c 1.35]
Pulled silly macro to try to disuade the direct use of assert()[src/gserror.h 1.8]
2004-12-08 00:31 Alex Cherepanov
Provide back-up definitions of /-| /RD /|- /ND /| /NP for the benefit of embedded PDF fonts that forget to define them. Issue a warning when they are used. Don't fix PS interpreter because Distiller doesn't accept such fonts either. fix bug 687824[lib/pdf_font.ps 1.72]
forgot an #undef to correctly disable assert()[src/gsmisc.c 1.21]
Moved include outside of function body to fix MSVC compile error.[src/gsmisc.c 1.20]
Added macros for assertions: GS_ASSERT(false) returns -1 in a release system asserts in a debug system GS_DBG_ASSERT(false) is a NOP in a release system asserts in a debug system Both versions will printf to stderr first. Raw assert() should not be used. GS_ASSERT will not compile in a void function, as it returns -1. This means you can not use assertions to change the standard error return exception handline mechanism in Ghostscript. You can use them to catch programmer usage errors in a debug build. gs_misc::gs_assert() is the one place the operating system's assert is called. This can be modified in a embedded system, again assert is only called in a debug build.[src/fapi_ft.c 1.13, src/gdevddrw.c 1.26, src/gdevpdfc.c 1.50, src/gdevpsf1.c 1.19, src/gdevpsft.c 1.34, src/gdevpx.c 1.15, src/gendev.c 1.6, src/gserror.h 1.7, src/gsfcmap.c 1.26, src/gsfunc0.c 1.22, src/gslibctx.c 1.6, src/gsmisc.c 1.19, src/gxccman.c 1.29, src/gxcht.c 1.14, src/gxdhtserial.c 1.6, src/gxfdrop.c 1.15, src/gxpflat.c 1.43, src/gxshade1.c 1.34, src/gxshade6.c 1.85, src/gzspotan.c 1.10, src/siinterp.c 1.6, src/write_t1.c 1.4, src/write_t2.c 1.6]

Fix : Disable an unuseful warning from MSVC8.[src/msvccmd.mak 1.23]
Correct an incorrect cast in the jpx filter. Bug 687831.[src/sjpx.c 1.11]
Add a const qualifier to the jpx filter memory contest. Corrects an error with Metrowerks CodeWarrior 8.[src/sjpx.h 1.4]
Remove the calls to set the TEXT filetype for the source files. This has not been necessary for the last few versions of CodeWarrior, and doing it correctly for the hierarchical jasper source is tedious.[src/macos-mcp.mak 1.30]
Add jasper.mak to the MacOS CW build.[src/macos-mcp.mak 1.29]
Enable compilation of the jasper library source for JPEG 2000 image stream support in the MacOS Code Warrior build.[src/macos-mcp.mak 1.28]
2004-12-06 13:17 Igor Melichev
Fix : Improvinmg documentation for recently improced algorythms. DETAILS : This patch only changes comments in C code. EXPECTED DIFFERENCES : None.[src/gxfill.c 1.120, src/gxfillsl.h 1.7, src/gxfilltr.h 1.10, src/gxshade6.c 1.84, src/gzspotan.c 1.9]
Decide to run a recursive configure for the jasper source based on existence of the new jas_config_ac.h instead of the old jas_config.h We now require the 1.701.0-gs2 (or later) release to build out of the box. Other versions can still be used by running their configure manually and touching this file, or by building a separate shared library.[src/configure.ac 1.49]
Add JPXDecode filter to the default Windows MSVC build. This is based on the "jasper" source and must be at least version 26 from the svn repository using svn co http://svn.ghostscript.com:8080/jasper/trunk jasper DETAILS: This is a fairly minor modification to the gs MSVC makefiles, but it did require changing our jasper version (that had accumulated many changes) to hook in the correct jas_config***.h file and to avoid using windows.h (so we can build with /Za). See the jasper svn for details of the changes. EXPECTED DIFFERENCES: none. (we didn't have any PDF 1.5 files with JPEG2000 images in the comparefiles).[src/msvc32.mak 1.67, src/winlib.mak 1.24]
Fix: in implementation of n operator in clip mode, put pathbbox in stopped context so that completely empty paths have the same behavior as paths with empty bbox, rather than causing an error. Fixes bug #687820. DETAILS The test file has a "n W n" sequence, which is a request to clip to a totally empty path. The error comes from code added to pdf_ops.ps v 1.33 to handle the case where a path is defined but has an empty bbox. See bug 687136 for more details on this change. Comment #8 of that bug report suggests that our PDF interpreter always maintains a currentpoint, which would justify the use of an unprotected pathbbox. However, that assumption seems to be false. This fix wraps the pathbbox added in the 1.33 change in a stopped context.[lib/pdf_ops.ps 1.37]
Add a platform-specific JASPERCFLAGS makefile variable to assist with proper compilation of the jasper jpeg2k library. Set this variable correctly in the autoconf build. DETAILS: The jasper library natively supports building under both autoconf+cc and MSVC, but expects a preprocessor define to be set to distinguish the two. While we do carefully construct a special JAS_CC for compiling the jasper source into Ghostscript, as with all the other 3rd party libraries, there is only a facility to set special CFLAGS globally. This change adds a new top-level makefile variable for passing platform-specific CFLAGS into gs.mak for addition to that global set. Also, set JASPERCFLAGS=-DJAS_CONFIGURE in Makefile.in so that the jasper sourcr expects the autoconf generated configuration header when compiling as part of Ghostscript.[src/Makefile.in 1.40, src/gs.mak 1.28]
Return error code when using -f filename. Fix bug #687811 strange behavior with -f.[src/imainarg.c 1.34]
When doing a Windows debug build, link against the debug run time libraries.[src/msvccmd.mak 1.22]
Correct the SubfontID values in the example substitutions.[doc/Use.htm 1.124]
Correct errors in .buildnativefontmap procedure. DETAILS: The enumeration of fonts returned by .getnativefonts was being given "array true" which was causing a typecheck in forall because of a missing exch. It should have been "true array". Also, .findfontname was returning a name rather than a string, so cvn was failing because it was already a name.[lib/gs_fonts.ps 1.48]
When using CJK Windows TrueType fonts, add the Windows fonts directory to the GS_LIB registry variable to allow access to this directory when SAFER is used.[src/dwsetup.cpp 1.10]
2004-11-23 12:18 Igor Melichev
Fix (TT interpreter) : The component 'usage' buffer size was wrongly computed. DETAILS : Bug 687810 "/invalidfont in --@0x1e36c". Note that the error message appears some misleading due to sbx, sby is placed in ostack for type42_finish. Rather we could fix it in this particular case in type42_finish, a complete fix appears too complicated. So for now leave it as it is. EXPECTED DIFFERENCES : None.[src/ttfmain.c 1.32]
2004-11-23 07:44 Igor Melichev
Fix (type 1 hinter) : Bugs in 'flex' with disabled hinting. DETAILS : Bug 687812 "Distortion in charpath outline". 1. Wrong poles were exported from the hinter when 'flex' works with disabled hinting. 2. Improved vdtrace commands for a disabled hinting. EXPECTED DIFFERENCES : None.[src/gxhintn.c 1.56]
Null the DEVICE_DEVS_EXTRA variable when calling the link line. This works around env space limitations on some vendor unicies when a large set of devices are passed from the make command line through this variable. Bug 687804.[src/unixlink.mak 1.7]
Cast the gx color index to an int inside the switch argument to avoid problems with the HP-UX 10 compiler which does not accept 64 bit arguments to switch(). Bug 687804.[src/gdevstc.c 1.11]
Bump the version number after the 8.33 beta release.[doc/News.htm 1.157, lib/gs_init.ps 1.114, src/gscdef.c 1.50, src/version.mak 1.78]

Define SHARE_JASPER=0 by default in the windows build. This doesn't enable anything, but makes it easier to get going.[src/winlib.mak 1.23]
Due to an oversight, JBIG2Decode was omitted from the windows build. Now it is included in the default FEATURE_DEVS although in the future this should probably be moved to the pdf.dev[src/msvc32.mak 1.66]
Add some missing initializers for glyph_data_t->memory. Related to the 687459 fix.[src/gdevpsf1.c 1.18, src/gdevpsf2.c 1.33, src/gdevpsfu.c 1.12, src/gsfcid.c 1.13, src/gstype42.c 1.48, src/gxfcopy.c 1.54, src/gxtype1.c 1.41, src/zchar1.c 1.42, src/zfcid0.c 1.25, src/zfcid1.c 1.23]
Copies over new-style color procs when making a null device with a target, to avoid inconsistent states. Fixes bug #687770. DETAILS The problem was a null device (for implementing stringwidth) with inconsistent color info; the color_info struct specified 4 components, but the get_color_mapping_procs was gx_default_DevGray_get_color_mapping_procs, which is the desired value for null devices instantiated through gs_copydevice (i.e. -sDEVICE=null). As a result, cm_comps[1] through [3] were left uninitialized, and, when negative, would crash the halftone logic. This patch copies over the new-style color mapping procs (the old-style were already copied) in the gs_make_null_device routine. A strong argument could be made for changing the logic in gx_device_copy_color_procs() instead, but it was felt that this change was more localized. Dan reviewed this patch during a phone conversation, so I am going ahead and committing. I'm also opening a new bug to encourage a closer look at other uses of gx_device_copy_color_procs() to see whether a change there is beneficial or harmful.[src/gsdevice.c 1.24]

Update Windows installer to use the current name for the license file, Public.htm not the older PUBLIC.[src/winint.mak 1.23]
Add utility mkcidfm.ps to create a cidfmap file based on fonts found in a directory. Change MS-Windows installer to optionally update lib/cidfmap with the CJK fonts found in the Windows font directory. DETAILS: Ghostscript does not ship with CJK fonts. If support for Chinese, Japanese or Korean is added to MS-Windows, CJK TrueType fonts and font collections are added to the MS-Windows fonts directory. These can be used by ghostscript by specifying mapping and aliases in the lib/cidfmap file. This patch looks in the MS-Windows fonts directory for known CJK fonts, and if present it appends appropriate mappings or aliases to the lib/cidfmap file. The font names and aliases are currently fixed, but can be changed by editing mkcidfm.ps. A new checkbox is added to the installer dialog "Use Windows TrueType fonts for Chinese, Japanese and Korean" Only if the user selects this will lib/cidfmap will be updated. The default behavior is that lib/cidfmap is unchanged.[doc/Psfiles.htm 1.55, lib/mkcidfm.ps 1.1, src/dwinst.cpp 1.6, src/dwinst.h 1.7, src/dwsetup.cpp 1.9, src/dwsetup.h 1.6, src/dwsetup.rc 1.12, src/dwuninst.cpp 1.5]

Fix (pdfwrite) : Page context stream was not properly formed when starts with an invisible text. DETAILS : Bug 687797 "pdfwrite generates invalid pdf". The improved condition made consistent with gdevpdte.c ln 501. EXPECTED DIFFERENCES : None.[src/gdevpdtt.c 1.94]
Fix for Bug 687459 (SEGV) addressing several problems: (i) Elements fetched from a font dictionary have to be dereferenced into a ref since pointers change if the dictionary is resized (to add entries); (ii) The glyph_cache used by gs_font_cid2 fonts needs to be in stable memory since elements might be added after a 'save' and the list will still be refereced by the font, so cannot be freed by 'restore'; (iii) The gs_glyph_cache__release was never being called so creating a memory leak -- font notification (called by gs_font_finalize) is now used to free the cache list; (iv) The gs_glyph_cache__release did not work (probably was never tested since it was not being used). DETAILS: Using stable_memory means that the objects created need to be freed properly, that's why the font_notify mechanism was used. This fixes the problem reported by the bug and doesn't seem to have created any other problems (regression test passed). A 'memory' element was added to the gs_glyph_data_s structure so that the 'bits' can be allocated using the desired memory (stable memory in the case that we are using the cache). This was deemed preferable to always using the pfont->memory->stable_memory since changing to this might cause other problems. This did create a fair number of changes since every place the get_outline was used, the glyph_data structure needed to have the 'memory' element set. We could have used 'NULL' to signal pfont->memory, but this might have masked uninitialized memory issues that can be tracked with tools such as valgrind. The gs_glyph_cache__release was totally broken, and since it was not previously used, fixing and testing it presents no risk of other clients relying on broken behaviour. The implementation of the cache is VERY RUDIMENTARY -- a linked list of elements with a hard-coded number (32767) limit to the size of the cache. The size is too small to be useful for Asian fonts, but making it bigger will result in a lot of time spent finding a 'miss' condition. At least the current logic has LRU slot re-use behaviour (which should be retained). Fixing this, and making the cache limit larger are left for a later change (post 8.50 release). EXPECTED DIFFERENCES: None.[src/gdevpsft.c 1.33, src/gsgcache.c 1.3, src/gsgcache.h 1.2, src/gsgdata.h 1.5, src/gstype42.c 1.47, src/gxfcopy.c 1.53, src/gxttfb.c 1.36, src/zbfont.c 1.28, src/zfcid0.c 1.24, src/zfcid1.c 1.22]

Fix : toolbin/pdfinflt.ps did not decompress some streams (continued). DETAILS : The 2nd Patch from SaGS for the bug 687746 "gs\toolbin\pdfinflt.ps doesn't unpack a stream" The previous patch contained on over-optimization that leaded to a corrupted operand stack. "{ [ {proc} {proc} ] }" (note: 2 identical inner procs) can be optimized: either as "{ [ {proc} dup ] }" - use VM for only 1 copy of "{proc}" or as "{ { {proc} {proc} } }" - the 2-element array is allocated only once, by the parser, not at each execution of the enclosing proc but we cannot apply both these optimizations at the same time. This error affects PDF files that include a /Filter and/or /DecodeParams specified as 1-element arrays. PDFs for which these entries are a single name (for /Filter) or dict (for /DecodeParams) or arrays with 2 or more elements are not affected. EXPECTED DIFFERENCES : None.[toolbin/pdfinflt.ps 1.7]

Fix : Cygwin/gcc warnings. DETAILS : Cygwin/gcc claims an undefined result in spdiff.c due to possibly undefined order of evaluation of operands of a binary operation. The hunk #2 now sets 'ti', rather the old code does not. But we believe that the change is algorithmically equivalent. EXPECTED DIFFERENCES : None.[src/gxdevndi.c 1.5, src/spdiff.c 1.8, src/ttinterp.c 1.16]
Remove some obsolete assert calls which caused problems on some platforms due to incorrect string quoting in assert.h.[src/gxhintn.c 1.55]
Fix: Python opens files in text mode unless "rb" is needed.[toolbin/tests/cmpi.py 1.2]
Add an interactive image compare tool written in Python by a Python neophyte. Not quite ready for prime-time, but an interesting enough start to commit. Even though there are bugs in the differencing, responsiveness and memory usage, it is still sometimes useful. If a version # were to be applied to this, I would call it 0.1 (at least it is a positive number).[toolbin/tests/cmpi.py 1.1]
Update the MacOS X platform-specific makefile. Remove -traditional-cpp. This was added to work around bugs in earlier releases of Apple's gcc, but it is not necessary with more recent releases, and conflicts with newer cpp features used by more recent Ghostscript code. Partial fix for bug 687787.[src/macosx.mak 1.25]
Improve documentation for CID fonts.[doc/Use.htm 1.120]
Include stdio_.h instead of the system header according to C style.[src/gslibctx.h 1.5, src/lib.mak 1.203]
Add handling for missing EOL following the %PDF-#.## string in the header. Yet another bad file that Acrobat Reader handles. Bug 687781. DETAILS: If we get an error doing the 'cvr' to get the version #, trim a character from the end of the string and try again. Stop if the string becomes empty.[lib/pdf_main.ps 1.88]
Add missing opening quotes to the error printouts. This typo came in as part of an earlier bug fix and prevented compilation. Bug 687784.[src/gdevsppr.c 1.9]
Fixes Bug#687762. Includes the date specification of the CVS checkout in the baseline update log. This then gets propagated to the daily reports.[toolbin/tests/update_specific 1.4]

Fix (pdfwrite) : Forget cancelled resources. DETAILS : Bug 687749 "PS to PDF generates very large PDF document" 1. An indeterministic bug fixed in gdevpdfi.c, hunk #1. 2. Implemented a recognition of equal patterns in gdevpdfi.c and provided a PDF pattern substitution. We caould not provide a substitution in the PS interpreter because an accumulated pattern instance doesn't point to the corresponding client color. 3. pdf_forget_resource is applied when a resource is cancelled and is not longer needed. This applies to all redundant resources except patterns, because patterns keep the substitution data. We would like to save memory from substitured patterns with a special substitution table, but we have no time for such optimization now. 4. The function pdf_forget_resource is some slow because the data structure was not designed for removing resources from lists. We would like to implement dual linked lists, but we have no time for such optimization now. 5. Since pdf_forget_resource is not applied to patters, we need to prevent a big growth of the number of stored patterns. We implemented pdf_drop_resources for that purpose and drop all substitured pattrens after 300 ones have been accumulated, but not frequenter than once per page. This solution isn't perfect, but should work for most cases. If a substituted pattern is dropped erroneusely, it will be accumulated again, maybe causing some slowdown. 6. Implemented a new device parameter PrintStatistics. The new function pdf_print_resource_statistics prints a statistics to stdout. EXPECTED DIFFERENCES : None.[src/gdevpdf.c 1.101, src/gdevpdfg.c 1.59, src/gdevpdfg.h 1.34, src/gdevpdfi.c 1.57, src/gdevpdfj.c 1.32, src/gdevpdfp.c 1.40, src/gdevpdfu.c 1.61, src/gdevpdfv.c 1.37, src/gdevpdfx.h 1.103, src/gdevpdti.c 1.39, src/gdevpdtt.c 1.93]
Exempt three new files from the multiple-include protect check. Like the previous exemptions, these are templates that must be instantiated multiple times to function properly.[toolbin/tests/check_source.py 1.11]

Fix (type 1 interpreter) : Replaced Metrics was missed. DETAILS : Bug 687614 "mirrored glyph is rendered at incorrect position". This patch fixes the problem for raster devices. Without -dNOCACHE the behavior was indeterministic due to uninitialized cxs.use_FontBBox_as_Metrics2 in zchar1.c. We ported the change from gstype1.c to gstype2.c with no special testing because we have no practical examples of Type 2 with a replaced lsb. It happens so because Type 2 only appears in PDF, which doesn't replace lsb. EXPECTED DIFFERENCES : None.[src/gstype1.c 1.32, src/gstype2.c 1.36, src/zchar1.c 1.41]

This is the third beta release leading up to the stable 8.5x series. It contains numerous bug fixes since the last testing release, but a few outstanding issues remain.
New features since the last stable release:
Topological grid fitting, an original method developed for Ghostscript by Dr. Igor V. Melichev, improves the rendering of True Type fonts at small resolutions. See the documentation for GridFitTT for information on this feature.
The PDF writer now implements PDF 1.4 encryption. See the encryption parameter documentation for more information.
A new rendering method for shadings, developed for Ghostscript by Dr. Igor V. Melichev, improves the quality and performance of rasterization on continuous tone devices. The new method allows hardware or software acceleration with help of customizable routines for filling areas with a linearly varying color. functions.
This version contains the first release of Rinkj, an experimental new driver for some inkjet printers using ETS screening. See the Rinkj section for more information.
We now support PDF 1.5 files, including the new compression and encryption modes.
We have beta support for JPEG 2000 compressed images, using the JasPer compression library. This is only enabled as part of the default build in the autoconf (POSIX) build system in this release.

Fix (pdfwrite) : Glyph positions were wrong for vertical CID fonts (continued). DETAILS : Bug 687603 "vertical text misplaced after distilling", reopened. Bug 687753 "Text not aligned when viewed with Acrobat Reader", re-testing. Disposition : D1. The PDF spec requires X-compomenent of v-vector always equals to half glyph width. D2. AR5 appears to use W|DW to compute the X-component of the v-vector of WMode 1. The previous patch fixed most problems, but one left unfixed. When a glyph is used with WMode 0, and later with WMode 1, the second usage doesn't store Width and V due to the 'used' flag is already set. This patch introduces 2 separate sets of flags for WNode 0 and WMode 1. Changes : 1. Defined a new field 'used2' fro WMode 1 in gdevpdtf.h . 2. Allocated the used2 array, provided garbager methods, and a resizing on demand in gdevpdtf.c . 3. gdevpdtc.c sets used2. 4. Improved the computation of the v-vector in gdevpdtt.c . Now pdf_glyph_widths should be conforming to (D1) and (D2). 5. The coordinate adjustment in gdevpdte.c is not longer useful due to (4). Removed. 6. When writing W, W2, glyphs are being enumerated with used, used2 correspondingly (gdevpdtw.c). 7. The accedd to Widths2 sometimes was incorrect. Now fixed (gdevpdtf.c). 8. gdevpdtc.c misused Widths2 as Widths when storing the WMode 0 width as a component of theWMode 1 v-vector. Now fixed.

Fix (pdfwrite, PDF interpreter) : Glyph positions were wrong for vertical CID fonts. DETAILS : Bug 687753 "Text not aligned when viewed with Acrobat Reader". Disposition : D1. The PDF spec requires X-compomenent of v-vector always equals to half glyph width. D2. AR5 appears to use W|DW to compute the X-component of the v-vector of WMode 1. Changes : 1. With WMode 1, pdf_obtain_cidfont_widths_arrays obtains both Widths and Widths2 arrays (gdevpdtf.c, gdevpdtf.h, gdevpdtc.c). 2. For CID fonts gdevpdtc.c computes both WMode 1 and WMode 2 width when WMode 1 is requested. 3. Due to (D1), must compensate the half width when computing a glyph position in gdevpdte.c (hunk #2). 4. In gdevpdte.c internal data glyph_origin_shift used opposite signs for CID and non-CID fonts. Now made uniform. 5. The Type 0 font matrix and the descendent CID font matrix were applied in a wrong order in gdevpdte.c . 6. To satisfy (D2) when WMode 1 is only requested, write DW 0 when WMode 1 is only requested. 7. After fixing all above, from the test file of the bug 687753 pdfwrite generated a PDF, which GS failed interpret due to a curious failure with e_dictfull while checking for an absent key /File in the font dictionary. Patched zfcid1.c to provide a tolerance. Meanwhile we're not sure that it's the best way for fixing that, so if someone can bring a better method, feel free to improve. 8. The PDF interpreter is patched to comply with (D2) - pdf_font.ps, hunk #2 . 9. Fixed a bug in .pdfMakeInternalMTXArray : W2 arraytype elements wrongly computed the range (debugged with re-distilled Bug687603.ps). EXPECTED DIFFERENCES : Bug687603.ps besides that, it generates an improved PDF for japan-.ps, Type11CDevProc.ps, but rasters appear same because a change to the PDF interpreter compensates changes to the PDF writer.[lib/pdf_font.ps 1.70, src/gdevpdtc.c 1.38, src/gdevpdte.c 1.63, src/gdevpdtf.c 1.39, src/gdevpdtf.h 1.24, src/gdevpdtw.c 1.33, src/zfcid1.c 1.21]

DETAILS : Fixes the reopened bug 687660 "incorrect font rendering/missing glyphs from ps2pdf". pdf_is_same_charproc1 now checks whether we try to replace a charproc with one taken from a font with a compatible Encoding. Before now the encoding was ingnored, causing a subsequent failure (due to an encoding conflict) when adding glyphs to the font copy, and an infinite loop. As usual, the encoding compatibility is being checked within the list of characters of a current text.

(pdfwrite) : Implementing a dynamic recongnition for Type 3 charproc variations (continued 8). Allocate a single character list per text. DETAILS : This change is algorithmically equivalent. It's a preparation for fixing the reopened bug 687660 "incorrect font rendering/missing glyphs from ps2pdf". For 1-byte fonts now we allocate a singe instance of pdf_char_glyph_pairs_t for storing the character list for entire text. Now it is done once per text as an extention to pdf_text_enum_t. The intention is to provide an access to it from pdf_find_same_charproc. CID text is still processed in chunks, which are delimited by font changes or CDevProc callouts. It may cause a searchability problem with some viewers, when converting a composefont with a Type 3 descendent. But unlikely we'll met such case in practice, due to we have no exmples of composefont with a Type 3 descendent. We would like to improve the CID text processing sometimes with with building a complete character list for a text portion delimited with font changes. The new algorithm for scan_cmap_text should be like this : first delimit a single font portion, then construct the character list for the portion, and then process the portion with possible CDevProc and charproc callouts.

Fix : toolbin/pdfinflt.ps did not decompress some streams. DETAILS : Patch from SaGS for the bug 687746 "gs\toolbin\pdfinflt.ps doesn't unpack a stream" Current version of pdfinflt.ps uncompresses only streams that have a single filter applied, and only if that single filter is /FlateDecode. Proposed patch (attached) ads support for procesing streams with multiple filters. However, not all decompressing filters can be removed, and not in all cases it would be desirable to remove them. The /filterstoremove dictionary lists filters that are to be processed, and omits filters that are to be preserved in the output. For streams with multiple filters chained together, the new version of pdfinflt.ps removes all filters from the first in the decompressing chain up to, but excluding, the first filter that is to be preserved. The list of preserved filters, with the reason why these are not removed, follows: /RunLengthDecode, /CCITTFaxDecode, /DCTDecode: These are normaly used for compressing raster images. I assume the main purpose of this tool is to decompress page streams for debugging, and decompressing images only adds a huge amount of binary data, making harder to find and examine content streams. If this is not the case, and getting raw image data is necessary, simply uncomment the lines corresponding to these filters. /JBIG2Decode, /JPXDecode: There's no (standard) PostScript filter that corresponds to these PDF filters. (I think) GhostScript implements these filters in the PostScript interpreter, but not for all platforms, so I added some detection code for them. The preceding paragraph applies too, so I left the lines corresponding to these filters commented out. /Crypt (PDF1.5-specific): This is a generic interface with decryption plug-ins, and has no PostScript counterpart (and I don't see how it could have one).

Fix (pdfwrite, PDF interpreter) : Correctly handle different widths for same glyph (continued). DETAILS : This patch continues a long story about the handling of different widths for same glyph in a PDF embedded font. The last patch in this series was http://www.ghostscript.com/pipermail/gs-cvs/2004-September/004834.html That patch caused a problem with pdfwrite, which needs to write an original glyph name rather than a substituted one. This change establish a new discipnile for passing the original glyph name from the PDF interpreter to pdfwrite inside a substituted glyph name, with using an implementation specific separator (~GS~). Before writing a font, we apply copied_drop_extension_glyphs to remove extended glyph names. We don't like to modify the font, but choose this minimal solution for now. A better solution would be to introduce another flag to glyph slots to mark ones, which to be skipped when writing the embedded font. Bug 687740 "(pdfwrite) A character dissappeared in ADOBE1-4.pdf".

Fix LZWEncode filter to use the EarlyChange parameter and also correct the tifflzw device to initialize EarlyChange to the proper value (1). Bug 687726. DETAILS: The LZWEncode filter failed to use the EarlyChange param but the LZWDecode did honor this setting. The LZWEncode always acted as if EarlyChange = 1 which since that was the default, worked as long as the Decoder wasn't set for EarlyChange == 0. Also, now that the Encoder honors EarlyChange = 0, the tifflzw device needed to have the flag set correctly (it needs EarlyChange == 1).

Don't overwrite CFLAGS variable if it is already defined. Bug 687739[src/msvc32.mak 1.64]
Fix initialization of C stack streams that did not perform s_init(). Bug 687709 that could result in a Segmentation Fault (SEGV) DETAILS: The normal s_alloc() streams included s_init() on the allocated stream, but C stack streams could have uninitialized elements in the stream struct. Since this was UMR related, and affected the clist mode, the jpeg device and the pswrite device (and possibly some pdfwrite data), this would be different on different platforms. The premature 'CloseTarget' action when the stream->close_strm was not initialized as 0 (false) would show up as a SEGV when the -Z@ was used. Other problems that this patch fixes are not linked to a test file at the current time. This change also corrects a trivial typo and a NUL character found in src/gxtype1.c as a header file related warning in src/imain.c[src/gdevjpeg.c 1.8, src/gdevlj56.c 1.6, src/gdevpdfc.c 1.49, src/gdevpdfm.c 1.47, src/gdevpdtb.c 1.28, src/gdevpdtw.c 1.31, src/gdevps.c 1.40, src/gdevpsf1.c 1.17, src/gdevpsf2.c 1.32, src/gdevpsft.c 1.32, src/gdevpsim.c 1.14, src/gdevpsu.c 1.18, src/gsfunc4.c 1.16, src/gxclimag.c 1.11, src/gxclpath.c 1.20, src/gxclrast.c 1.31, src/gxclread.c 1.13, src/gxfcopy.c 1.49, src/gxtype1.c 1.39, src/iccfont.c 1.10, src/imain.c 1.40, src/imainarg.c 1.33, src/stream.c 1.26]

Add TrivialCMYK color space, which simulates standard PostScript CMYK to RGB conversion on device-independent level. Fix bug 687711 [DETAILS] Recent versions of Adobe Acrobat simulate on screen the appearance of printed documents when the color of an object is specified in DeviceCMYK color space. The resulting dark colors can be undesirable for presentation graphics. TrivialCMYK can help when the user had RGB colors in mind, but for some reason used CMYK colors instead in the document.[Resource/ColorSpace/DefaultCMYK 1.4, Resource/ColorSpace/DefaultRGB 1.4, Resource/ColorSpace/TrivialCMYK 1.1]

Fix for 687706 Display device 8-bit native incorrectly dithers grays. This is a partial fix and also needs Dan Coby's fixes to the post DeviceN halftoning. The DeviceRGBK color model is added. DETAILS: Prior to GS 8, the display device 8-bit native format would use 32 gray levels to avoid halftoning, and a 4x4x4 color cube which did use halftoning. The halftoning logic was changed with the introduction of DeviceN and in GS 8 both grays and colors were being halftoned. The DeviceRGBK color model is added and used by the display device native 8-bit format. The RGB color space to RGBK color model conversion converts pure RGB grays to the K (black/gray additive) component. This allows the 32 gray levels to be recognised by the halftoning logic as being sufficient to avoid halftoning.[src/gdevdsp.c 1.30, src/gxcmap.c 1.23, src/gxcmap.h 1.12, src/zcolor.c 1.21]
Fix for 687718 The tiffsep device fails when the size of gx_color_index is 32 bits DETAILS: The comments on bug 687705 "Compile of 8.31 fails on OS/2" point out that the tiffsep device fails during device initialization if the size of gx_color_index is 32 bits. This is due to a recent change which made the default number of components for this device equal to 8. This works if the size of gx_color_index is 64 bits. But it fails with 32 bits. This fix changes the default number of components for this device to be based upon the size of gx_color_index. It also changes the psdcmyk device to use the same logic for its default number of components. This fix also includes changes to doc/Devices.htm which explains that the number of components will differ based upon the size of gx_color_index (and a link giving more details on gx_color_index). More information about the parameters for the tiffsep device is given including an example command line.[doc/Drivers.htm 1.49, src/gdevpsd.c 1.18, src/gdevtsep.c 1.5]

This is a partial fix for 687706 Display device 8-bit native incorrectly dithers grays. Russell Lang is improving the 8-bit (256 color) display device to allow more shades of gray. This change is required for that effort. DETAILS: The pre 8.00 release had more gray levels for the 8-bit display device but the pre 8.00 release had other related problems in halftoning. The fix for those problems eliminated the extra gray levels. Russell's effort dug up some problems with the handling of halftones for devices in which the max_color and max_gray values are different and gray_index is set to an actual component number. This fix corrects those problems. Russell has a patch for the remainder of the effort. His changes involve changing the 256 color display device to use a DeviceRGBK process color model: red, green, blue and an additive black (gray). New device color mapping procs also have been created for this process color model. (This is the first example of this process color model in Ghostscript.)[src/gxdevice.h 1.20, src/gxdevndi.c 1.4]

Fix (the filling algorithm) : Unite trapezoids if they have a common side. DETAILS : Bug 687716 "Assertion fails in gzspotan.c". The spot analyzer can't reconstruct the topology when there are two trapezoids with a common side. We patched the spot decomposition algorithm with uniting such trapezoids, because (1) it's too hard to unite them in the "spotan" device, and (2) the post-condition of the spot decomposer simplifies. For more details see a new comment in code. This patch causes a rendering difference. We believe that a big part of differences happens due to the bug 687717, which is currently unfixed due to the QA overload. If the bug 687717 is fixed before this patch, a small rendering difference can also appear, because we unite trapezoids by the equality of x_current, x_next, which have an arithmetic error. Therefore ununited trapezoids may have a pixel center between them, which is not painted, but shifting a boundary to x_current, x_next the pixel center may fall into a trapezoid, then it is covered by the union and painted. Besides that, with dropout prevention, a pixel set for the union of two trapezoids may differ from the union of pixel sets for ununited trapezoids when at least one of the trapezoids is narrow. Particularly, two narrow trapezoids may paint 2 pixels, but its (narrow) union does a single pixel. Contacting trapesoids are not regular in characters, which only use a dropout prevention, but the test file of the bug 687698 (same as for 687667) demonstrates some ones in a CJK TT font, which composes hieroglyphs from subglyphs with a deformation and shifting.

Fix : Pattern metrics was imprecize. DETAILS : Bug 687581 "A pattern truncated". This bug is a regression since the December 09 2003 revision. We still think that we insufficiently understand the Adobe's method, but now we've got one closer to CPSI than it was before the December 09 2003 revision. Particularly the pattern step now appears better than on December 09 2003. This patch includes a change, which is well defined by the math : the usage of float2fixed_rounded instead float2fixed. It is a part of the PRECISE_CURRENTPOINT stuff. The rest of the patch is a kind of hewristic. We guessed that a pattern size should always round up to allow a similar logics as for a clipping - "any part of pixel inside". As before December 09 2003, we improved the case with neither skewing nor rotation. A further work on the general case may be useful. At last, some old problems, which existed on December 09 2003, are still unfixed. An example is -r300 298-09.ps : a line appears outside the pattern box.

Fix SEGV caused by premature free of the bbox device with high level devices that use the bbox_device of the vector high level device. Bug 687631.

CDevProc|Metrics|Metrics2 did not work with CIDFontType 0. DETAILS : Bug 687681 "Character spacing incorrect". The old implementation, which comes from the gs-cjk team, has a bug accessing the replaced metrics of a CIDFontType 0 font, which effectively caused the replaced metric to be ignored with CIDFontType 0 fonts. 1. Bug : With CIDFontType 0, CDevProc|Metrics|Metrics2 was searched in the descendent type 1 or 2 font rather than in the parent type 9 font. 1.1. A Type 9 font needs to be accessed via a descendent Type 1|2 font in pfont->procs.glyph_info. Added a new field gs_type1_data_s::parent, and provided an access through it with a new function gs_font_parent. 1.2. Metrics|Metrics2 is now accessed through gs_font_parent. 1.3. To access CDevProc implemented a new function zchar_get_CDevProc, which also works through gs_font_parent. 1.4. gs_type1_data_s::parent needs to reset while a type 9 font finalization, due to a reason, which we could not understand for sure. Likely descendent fonts appear to have a bigger lifetime than their parent type 9 font. Probably the descendents are pointed from somewhere besides FDArray (maybe the font registry ? or maybe after scaling the type 9 font from a type 9 copy ?), and we think it's not good. We believe that they should be released together with the type 9 font. For now leaving it as it is, working around with a hack notify_remove_font_type9. 1.5. In stable font copies gs_type1_data_s::parent is set to NULL to simplify the finalization. They are not used now. 2. Bug : In some cases the glyph bytecode was used instead the CID as a key for searching a Metrics|Metrics2 element (zchar1.c). 3. Bug : The PDF interpreter wrongly scaled W,W2,DW,DW2 for CIDFontTYpe0 (pdf_font.ps). 4. pdfwrite : Improved the generation of W, W2 for CID fonts, because after implementing (1) re-distilled 401-01.ps rendered incorrectly. 4.1. Prefer a non-zero width when computing DW, DW2 (gdevpdtw.c) (debugged with 401-01.ps). 4.2. Don't skip zero W, W2 elements. The old code recognized zeros as unused glyphs, but must do with the real glyph set in the font copy (debugged with the test file of the bug 687681). 5. zcharstring_outline still ignores CDevProc. We believe that it is correct, because it is used to compute font features with no dependence on the relaced metrics. 6. pdfwrite : Allowed a CDevProc callout for CIDFontType 0, because pdfwrite needs to know replaced widths, as well as it was done a half year ago for CIDFontType2. Actually after implementing (1) pdfwrite stopped to work correctly when re-distilling a PDF file with CIDFontType0, due to now it uses W,W2,DW,DW2. 6.1. A new function z1_set_cache is defined for this purpose similarly to zchar42_set_cache. 6.2. gs_font_procs::glyph_outline now retrieves the side bearing and width. Added a new argument 'sbw' to all implementations. 6.2.1. Currently this function extension is implemented for charstring fonts only, which need to interpret a charstring to retrieve the info : type 1,2,9, because we don't want to run the type 1 interpreter 2 times for getting sbw and bbox. Other font types retrieve zeros, which currently are not used. 6.2.2. type1_cis_get_metrics has been made public. 7. We believe that the implementation of W,W2,DW,DW2 in the PDF interpreter, which was contributed by the gs-cjk team, is unreasonably overcomplicated, because it is based on CDevProc, which needs an interpreter callout, which appears extremily hard from pdfwrite. For now leaving it as it is (except a small improvement in (3)). We would like to generate Metrics, Metrics2 instead that.

Partial fix for 687657 Text in transparency mask yields rangecheck in discardtransparencymask. DETAILS: Three problems have been found with this file. The rangecheck is actually a secondary effect. The actual problem was a typecheck in setrgbcolor. However that error occurred inside a stopped context. 1) The file has a mask group. This group specifies a color space (CS). The previous code set the current color space to the given value. However the FillColorSpace and StrokeColorSpace were not set. As a result, a DeviceRGB color space was being used instead of the specified DeviceGray color space. This resulted in a mismatch in the number of operands when the color as set (1 versus 3). The fix consists of setting both StrokeColorSpace and FillColorSpace when a mask group contains a CS value. 2) The file uses scn for setting color values for a DeviceGray color space. FillColor and StrokeColor can contain wither a single numeric value (which is common but not required for DeviceGray) or an array of values for all other color spaces. The scn and SCN operators were always assuming that these values always contained arrays. The fix consists of checking for the non array cases in the operators. 3) The appearance produced by Ghostscript with the test file does not match Adobe. A solid magenta rectangle is produced by Ghostscript. Adobe shows magenta text. This problem is NOT fixed by this patch. Note: If the test file is opened with Illustrator CS and then saved, Ghostscript does produced the same appearance as Adobe for the saved file. The reason for the differences are not currently known. However there are some more details in the bug report on this issue.[lib/pdf_draw.ps 1.86, lib/pdf_ops.ps 1.36]
Fix for 687403 Poor halftoning for 16 color (4 bit) devices. DETAILS: This bug is a brother to bug 687390. That bug was for 256 color (8 bit) devices. Russell Lang suggested testing the 4 bit devices and they were found to have problems caused by the same logical error. The halftoning logic assumes that all components for a device have the same number of shades. This was not true for the implementations of the 4 and 8 bit color devices. This fix converts the 16 color devices to using a 2x2x2 cube. Note: A possible future enhancement would be to convert these devices to using a 4 level gray for shades of pure gray (R = G = B).[src/gdevbmp.c 1.10, src/gdevdsp.c 1.29, src/gdevmgr.c 1.7, src/gdevmswn.c 1.12, src/gdevpccm.c 1.7, src/gdevpccm.h 1.8, src/gdevpcfb.c 1.6, src/gdevpcx.c 1.8, src/gdevpm.c 1.10, src/gdevpng.c 1.11]
Fix for 687664 tiffsep sometimes producing apparently corrupt files sometimes. DETAILS: The tiffsep device did not properly handle multiple page input files. This change adds multiple page handling to the tiffsep device. Most of the various tiff related routines already properly handled multiple pages so changes were only required inside the tiffsep device. The changes consists of: 1. Moving several variables which were local to tiffsep_print_page into the tiffsep device structure and adding initialization. These variables provide state information to the general tiff handling routines and the file pointers for the separation files. 2. Add logic for determining if the output file name includes a numeric format specification. If so then we create individual separation files for each page. If not then we create a single file for each separation. 3. A device close procedure was added to ensure that the separation files were closed.[src/gdevtsep.c 1.4]

Fix : Degenerate curves could cause a too big number of flattened curve segnments. DETAILS : Bug 687653 "-dNOTRANSPARENCY still allocates large buffers".

With this change degenerate curves will render as line segments. EXPECTED DIFFERENCES : golfer.eps At 72dpi (a 2 pixels difference).[src/gxpcopy.c 1.23]

Use PSOBJDIR as a staging area for the name-rewritten scripts at unix install time.

Fix (PDF interpreter) : Correctly handle different widths for same glyph. DETAILS : Bug 687672 "incorrect font rendering". An Encoding may specify various character codes for same glyph, and Widths may specify different widths for those codes. Thus same glyph may be used with different widths. This patch continues a long story about the handling of different widths for same glyph, which includes my old hacks (pdf_font.ps Revision 1.22 and 1.26) and Alex's change pdf_font.ps Revision 1.57 . Alex defines new glyph names for same glyph to resolve the widths conflict. After the Alex's change my old hacks appear low useful, and can be removed. This patch 1. Removes the hacks; 2. Improves the Alex's change with the case when CharStrings has no referred glyph (debugged with 1_2001.pdf) 3. Improves the Alex's change with minimizing a number of newly generated names, because the test file of the bug 687672 maps many charcodes to .notdef with various widths.

Ignore MediaPosition when selecting a media type. Adobe CPSI does it this way, and the PLRM suggests that this is advisory only. Bug 687547 for customer 780. DETAILS: Adobe CPSI also ignores this parameter without generating any error or warning. The PLRM says: This parameter does not override the normal media selection process described in the text, but if specified it will be honored--provided it can satisfy the input media request in a manner consistent with normal media selection--even if the media source it specifies is not the best available match for the requested attributes. Since an input PS file is unlikely to have a PPD that accurately reflects the 'slot' numbers of our InputAttributes dictionary, we also ignore this option and instead give the 'best fit' based on size and orientation (and other parameters that may exist).[lib/gs_setpd.ps 1.25]

A new implementation of shadings, step 83. DETAILS : This is a partial fix for the bug 687585 "A shading renders narrower than its background". It fixes various secondary problems : 1. gx_default_fill_linear_color_scanline could miss pixels at the end of the scanline (bug 687585 "A shading renders narrower than its background", the right boundary). 2. decompose_linear_color could miss pixels when swapping axes of the clip rectangle. (bug 687585 "A shading renders narrower than its background", the top boundary). Defined adjust_swapped_boundary and applied for this purpose. 3. mesh_padding cauld miss pixels when swapping axes of the padding. Defined adjust_swapped_boundary and applied for this purpose. 4. Moved the fill adjustment from gx_dc_pattern2_fill_path to gsshade.c and disabled it in the NEW_SHADINGS build, because NEW_SHADINGS build never needs it. Instead that it applies mesh_padding. The new function gx_dc_pattern2_fill_path_adjusted access the new functionality from outside gsshade6.c . Also renamed gx_dc_pattern2_fill_path_adjusted with gx_dc_pattern2_fill_path for a better reflection of its new purpose. 5. Implemented VD_TRACE_DOWN in try_device_linear_color. The old code did a misleading drawing. 6. Fixed a conflict of the 's' flag in the -T argument. Changed the documentation to reflect that.

Fix (Type 1 hinter) : A further improvement of the glyph rendering quality, step 1. DETAILS : This change is algorithmically equivalent, because new code is disabled wirth configuration switches listed below. 1. FINE_STEM_COMPLEXES 1.1. Stem complex could miss a common boundary. 1.2. Stem width could be distorsed due to a common boundary missing (Bug 687578 "T1 hinter disturbs stem width".). 1.3. Overall hint (if presents) should have a bigger priority. 2. ALIGN_BY_STEM_MIDDLE 2.1. A stem middle could be shifted too much due to independent grid-fitting of boundaries and the change 1.2 - see 'i' in ccc-.pdf attached to Bug 687578. Fixed with an improved alignment with t1_hinter__align_stem_to_grid. 2.2. This isn't applicable for top|bottom zones from the TT stem recognizer, because we want to force outer boundaries to keep the glyph height. 2.3. 033-52-5873.pdf defines "pseodo-stem" hints, which have only one boundary corresponding to real poles. recognize them with t1_hinter__mark_existing_stems, and don't apply the improved alignment, because those stems designate outer glyph boundaries, which we want to force the uniform glyph height.

Translate the name of the gs executable stored in the utility scripts at install-time on unix. Closes bug 686863. DETAILS: The autoconf build supports a --with-gs=option for setting the name of the Ghostscript executable, which is stored in the makefiles as '$(GS)', but scripts such at ps2pdf that expect to make invoke Ghostscript made no use of this variable, causing version skew at best, complete failure of that popular utility at worst. We therefore now rewrite the hard-coded name each time we install the utility scripts. [src/unixinst.mak 1.35]
Propagate autotools build system changes from the GS_8_1X branch. Use the proper macro for the 'rm' function, and a more specific test for locating the local libpng library source.[src/Makefile.in 1.38, src/configure.ac 1.48]
Change regression test flags to use new JOBSERVER flag. Older flags are retained to allow older regression testing to still use this module.[toolbin/tests/gstestgs.py 1.23]
Add some job server related support. The -dJOBSERVER option defines the ^D to start a new encapsulated job, and the ^D is changed to be a self- delimitting token in the scanner. Fixes 687079. DETAILS: For backward compatibility, -dNOOUTERSAVE is retained, but this does *NOT* define the ^D to start a new encapsulated job. As specified in the updates to doc/Use.htm, in order to avoid an /invalidrestore error, the input should be from stdin otherwise the restore done as part of the new job encapsulation (restore returns to the server state) will encounter a file object that was created after the encapsulation save. This allows 289-01.ps to complete IFF the -dJOBSERVER option is used during regression testing. Thus the only (eventual) regression change will be: 289-01.ps[doc/Use.htm 1.113, lib/gs_init.ps 1.111, lib/gs_lev2.ps 1.34, src/scantab.c 1.5]
Add missing memory argument in 'I' interp debug printing. Also remove local prototype for debug_print_ref in favor of using idebug.h. Fixes SEGV when using -ZI or (I) true .setdebug.[src/int.mak 1.129, src/interp.c 1.20]
Use the MTIME define from the stat module rather than a numerical index to specify the modification time in python. Propagates a similar change from gscheck_raster.py.[toolbin/tests/gscheck_pdfwrite.py 1.21]
Propagate memory pointer gs_malloc() changes to the optional lj3100sw device. Patch from Harald Koenig. Closes bug 687636.[src/gdevl31s.c 1.5]

Fix : Unwind an unintentional change to setup_image_compression. DETAILS : I guess that gdevpsdi.c revision 1.30 was unintentionally modified with the patch http://www.ghostscript.com/pipermail/gs-cvs/2004-August/004681.html EXPECTED DIFFERENCES : None.[src/gdevpsdi.c 1.31]
Fix for 687640 Unable to set default halftones for PDF. DETAILS: To support both PS level 1 and PS level 2 interpreting modes, Ghostscript defines two routines for setting a default halftone. PS level 1 does not support resources. Thus for PS 1 we have .setdefaultscreen which sets a default halftone which is defined inside of gs_init.ps. For PS 2, we have .setdefaulthalftone which is similar to .setdefaultscreen except that it also checks for a default halftone resource. The PDF interpreter's handler for the /HT gstate parameter called .setdefaultscreen if the parameter value was /Default. This fix changes the handler to use .setdefaulthalftone instead. This results in the PDF interpreter using the default halftone resource if it is present.[lib/pdf_draw.ps 1.84]
Fix ResourceForAll Category procedure to make sure that the path given by GenericResourceDir systemparam is included in the enumeration. Bug 687641.[lib/gs_res.ps 1.37]

Trap C stack overflow exception on Borland C and MSVC. Without the trap the application silently terminates when C stack overflows. Fix bug 687461 [DETAILS] Watcom C 1.2 doesn't need the trap. It is also the only compiler tested that converts trailing recursion to iteration. GCC 3.2 on Windows still generates programs that fail silently but I don't know how to fix this. GCC 2.95 on Linux reports the stack overflow.[src/dwmain.c 1.20, src/dwmainc.c 1.23, src/windows_.h 1.7, src/winint.mak 1.22]

Fix : Arcs were imprecise (continued). DETAILS : A previous patch had a minor portability defect : PRECISE_CURRENTPOINT was used before defined. EXPECTED DIFFERENCES : None.[src/gxmatrix.h 1.10]
2004-08-31 13:23 Igor Melichev
Fix : Arcs were imprecise. DETAILS : Bug 687584 "An extra element painting a circle.". The problem happened due to the PRECISE_CURRENTPOINT patch http://www.ghostscript.com/pipermail/gs-cvs/2004-March/004333.html appears incomplete : arcs were not improved. This patch fixes that. 1. Applied gs_point_transform2fixed_rounding in arc_add to be consistent with the precise current point. 2. Renamed float2fixed_rounding with float2fixed_rounded and made it global. 3. Moved the definition of PRECISE_CURRENTPOINT to the appropriate scope. We leave many places in code, in which the unrounded transform is still applied, but those places do not deal with the current point.

Implementing Visual Trace for 'stroke'. DETAILS : It is necessary for analyzing the Bug 687584, and it is useful in general. EXPECTED DIFFERENCES : None.[doc/Use.htm 1.112, src/gxfill.c 1.118, src/gxstroke.c 1.11, src/lib.mak 1.193, src/vdtrace.h 1.13]
Fix for 687607 Text missing with TextALphaBits=2 and tiffsep device. DETAILS: The TextAlphaBits and GraphicsAlphaBits device parameters were not working for devices with a depth of more than 32 bits. The fix involves replacing the copy_alpha device procs in the 40, 48, 56, and 64 bit memory devices with the gx_default_copy_alpha routine. These devices previously had a copy_alpha routine which did nothing. This was a mistake from when these devices were created as part of the DeviceN work.[src/gdevm40.c 1.2, src/gdevm48.c 1.2, src/gdevm56.c 1.3, src/gdevm64.c 1.3]
Fix for security problems with user parameters, in particular the /PermitFileReading array. Also corrects handling of parameter arrays that contain a 'mark'. Fixes bug 687559. Thanks to mat. Gh. Savulescu (SaGS) for the bug report and for a suggested patch.[lib/gs_lev2.ps 1.33]
This is a beta release of the development tree. It contains a number of new features and is made available for those interested in testing the new version before it becomes the next stable release.
This second beta contains a large number of bug fixes over the earlier 8.30 version.
New features since the last stable release:
Topological grid fitting, an original method developed for Ghostscript by Dr. Igor V. Melichev, improves the rendering of True Type fonts at small resolutions. See the documentation for GridFitTT for information on this feature.
The PDF writer now implements PDF 1.4 encryption. See the encryption parameter documentation for more information.
A new rendering method for shadings, developed for Ghostscript by Dr. Igor V. Melichev, improves the quality and performance of rasterization on continuous tone devices. The new method allows hardware or software acceleration with help of customizable routines for filling areas with a linearly varying color. functions.
This version contains the first release of Rinkj, an experimental new driver for some inkjet printers using ETS screening. See the Rinkj section for more information.
We now support PDF 1.5 files, including the new compression and encryption modes.
We have beta support for JPEG 2000 compressed images, using the JasPer compression library. This is only enabled as part of the default build in the autoconf (POSIX) build system in this release.
The following bug numbers were open at the time of release:

Update release notes and open bug list for the 8.31 beta release. Bump the release date as well.[doc/News.htm 1.150, src/version.mak 1.72]
Fix half-toning for display device, bug 687629. DETAILS: Prior to DeviceN, dither_gray/max_gray were used if ncomp==1. With DeviceN, dither_gray/max_gray are used if gray_index >= 0. The display device was not correctly setting gray_index for native 1-bit/pixel format.[src/gdevdsp.c 1.27]
Fix for image matrix having negative values. Thanks to Len Sorenson for submitting this patch (author unknown). Bug #687411. DETAILS: The error is using floor to round a value without checking if it might be negative first. There were actually two places that did this even though the patch that was originally submitted only was for one of them.[src/gximag3x.c 1.19]
Close the font file after the font has been processed (loaded into VM). This prevents a problem with using up too many file handles detected on Solaris. Thanks to Alex Cherepanov for the patch. Bug #687066. DETAILS: The patch has no effect on the cache. There is no point of not closing the file after the content has been copied to memory. On GNU/Linux GS has 250K VMThreshold and 1024 handles. That's enough. On Windows GS has 1M VNThreshold and 512 handles. This is still OK. On Solaris GS has 1M VMThreshold and 256 handles. Handles can be used up before garbage collection starts. The following program fails on Solaris. (a)(w) file closefile 1000 { (a)(r) file pop } repeat Dependence on VMThreshold indicates that GC is not activated by open(2) failing with EMFILE . This is a real bug, the patch is just a work around that we may need to fix later, but not likely to be a problem.[lib/gs_type1.ps 1.15]
Fix to close streams at EOF (not only filter streams), as required by the PLRM. Thanks to Alex Cherepanov for this patch. Bug #687505. DETAILS: This is similar to a patch that I had developed and tested prior to Alex's patch. I had tested my patch, then Alex's against the regression suite and determined that it does not cause any differences. Alex's patch conforms to my analysis of the problem and the fix.[src/stream.c 1.23]

Fix (TT interpreter) : Provide a tolerance to an inconsistent cvt length. DETAILS : Bug 687604 "/invalidfont in --show-- error". We analyzed UFST and Free Type 2. UFST has same problem. FreeType 2 provides a tolerance, which we port now. Note that now we don't port a tolerance for other CVT commands. EXPECTED DIFFERENCES : None.[src/ttinterp.c 1.14]

Fix (TT interpreter) : A minor portability problem. DETAILS : A preprocessor statement didn't start in the first column. Occasionally discovered readin the code. Some time ago it was claimed as non-portable. EXPECTED DIFFERENCES : None.[src/ttload.c 1.6]
2004-08-24 09:10 Igor Melichev
Fix : Makefiles missed a dependency. DETAILS : After rebuilding the last revision got a crash due to gp_mspol.c was not recompiled. Found out that gslibctx_h was wrongly defined in lib.mak . Also changed the including of stdio.h in gslibctx.h to a C library file (IMO it should be so). EXPECTED DIFFERENCES : None.[src/gslibctx.h 1.4, src/lib.mak 1.192]
Allow the display device row alignment to be changed from the default 4 bytes to 8, 16, 32 or 64 bytes. DETAILS: If the image is allocated in video display memory, an alignment such as 16 bytes (128-bit memory) may be required. This is implemented by making the underlying memory device use a larger width than the display device.[src/gdevdsp.c 1.26, src/gdevdsp.h 1.10]
Changed iapi to use a void* instead of a gs_main_instance pointer.[src/dmmain.c 1.4, src/dpmain.c 1.12, src/dwmainc.c 1.22, src/dxmain.c 1.14, src/dxmainc.c 1.10]
Changed iapi to use a void* instead of a gs_main_instance pointer. Cleaned up warning related to function pointer signature miss-matches. DETAILS: iapi.h no longer defines a type for gs_main_instance * This will likely need to be put back in for backward compatibility. The iapi interface now uses a void * instance handle reflecting that it is an opaque type to the outside world. Note that function pointer argument miss-matches generate warnings in msvc but not in gcc. These have been fixed.[src/dwmain.c 1.19, src/gdevpdtw.c 1.29, src/gdevpsf.h 1.27, src/gdevpsfm.c 1.15, src/gsalloc.c 1.22, src/gsccode.h 1.14, src/gscpixel.c 1.13, src/gscpixel.h 1.7, src/gscspace.c 1.18, src/gsdevice.c 1.23, src/gslibctx.c 1.4, src/gslibctx.h 1.3, src/gxccman.c 1.28, src/gxfcache.h 1.27, src/iapi.c 1.12, src/iapi.h 1.13, src/idict.c 1.12, src/ilocate.c 1.11, src/iutil.c 1.11, src/iutil.h 1.8, src/sdctc.c 1.6, src/zchar32.c 1.5, src/zcssepr.c 1.16, src/zfont.c 1.12, src/zpacked.c 1.7]
Add a PPD for PostScript to be used by ghostscript ps2pdf.[doc/Develop.htm 1.136, doc/Ps2pdf.htm 1.69, lib/ghostpdf.inf 1.1, lib/ghostpdf.ppd 1.1]
Enable progressive updates for the image window of the MS-Windows ghostscript command line program. Change update method to use a Windows timer. DETAILS: In the MS-Windows GUI executable (i.e. text window managed by ghostscript rather than using a system console window), the image window is progressively updated every second or so as each page is drawn. The console executable did not do this. The update code for both GUI and console executables is changed to use a timer. The display update code is called whenever particular device drawing operations happen, and if a timer is not already running, it starts an update timer. The minimum update interval is shortened from 1s to 100ms. The time to refresh the window is measured, and the update interval may be increased to make sure that updates account for no more than 10% of processing. The update interval is decreased if subsequent updates are much quicker. The timer is stopped by any sync.[src/dwimg.c 1.13, src/dwimg.h 1.10, src/dwmainc.c 1.21]
Fixed dependancies for gslibctx.h[src/int.mak 1.128, src/lib.mak 1.191]

Fix (pdfwrite) : Check for glyph name conflicts while font merging. DETAILS : Bug 687597 pdf created by pdfwrite has garbled text (spr 3994) 1. When a document embeds 2 fonts with same name, same hinting and same glyph names but different charstrings, the old code didn't compare charstrings and erroneusely merged fonts. 2. pdf_obtain_font_resource_encoded didn't compare the hinting because same_type1_hinting computed a too strong condition (this change is not strongly neccessary for the bug). EXPECTED DIFFERENCES : None.[src/gdevpdtt.c 1.87, src/gxfcopy.c 1.45]

Fix (pdfwrite) : Wrong glyph positions with CIDFontType2 with no vmtx. DETAILS : Bug 687603 vertical text misplaced after distilling . 1. When computing the glyph position, must account that we write DW2[0 0] when there is no vmtx. 2. Computing a DW2, the advance got a wrong sign. EXPECTED DIFFERENCES : None.[src/gdevpdtt.c 1.86]
Implementation of 687496 transparency and CMYK support. DETAILS: This change extends our current implementation of the PDF 1.4 transparency to include blending in a DeviceCMYK color space. There is also a partial implementation of a DeviceGray blending space. However I do not have a method of generating test data for a DeviceGray blending space. Currently the choice of a blending color space is based upon the process color model of the output device. Note: There two differences expected in the regression testing. These are with ai2.pdf and dina3_watermark.pdf.[src/gdevp14.c 1.26, src/gxblend.c 1.6, src/lib.mak 1.190]
Add PDFSTEP debug aid. Prints a step number at end of PDFDEBUG line, and sync's the display, then reads a number of steps to skip (== single step). This is rudimentary but somewhat useful. Invoked with -dPDFSTEP. [lib/pdf_base.ps 1.44]
Bump the version number after the last beta release.[lib/gs_init.ps 1.109, src/gscdef.c 1.44, src/version.mak 1.71]
Remove references to the FreeType license. Artifex Software, Inc. has purchased rights to the FreeType 1 code and the work included here is relicensed under the same terms as with the rest of the Ghostscript code.[LICENSE 1.4, doc/FTL.txt 1.3]
Add support for PDF single stepping debug aid (PDFSTEP). Actual interpreter changes made separately.[lib/gs_init.ps 1.108]
Handle invalid PDF's that use 0.0 font scaling (Tf operator). Fixes bug 687606 for customer number 780. DETAILS: If the font scale is 0.0, then just use a very small value. This may result in a small unwanted dot, but that is probably not an issue since it is an invalid value. The better approach for 'invisible' text is to use TextRenderingMode 3. The 'pdfformaterror' function is used to complain about this so the problem might get fixed by the PDF Creator.[lib/pdf_ops.ps 1.34]
Correct the previous MSVC 8 updates to allow compilation with debugging.[src/msvc32.mak 1.62, src/msvccmd.mak 1.21]
Added missing parameter types to prototype.[src/gpcheck.h 1.9]
Detect the version of Microsoft Visual C++ from the version of nmake.[doc/Make.htm 1.78, src/msvc32.mak 1.61]
Add support for compiling with the beta of Microsoft Visual Studio 2005, also known as MSVC 8. DETAILS: Add new MSVC_MINOR_VERSION=1 to distinguish Microsoft Visual Studio .NET 2003 (MSVC 7.1) from Microsoft Visual Studio .NET (MSVC 7.0) Add new MSVC_VERSION=8 for Microsoft Visual Studio 2005 Ignore deprecated warnings from MSVC 8 with /wd4996, because insecure CRTL functions like strcpy and sprintf are now marked as deprecated. Remove /Ze which is always the default and is unknown to MSVC 8. Replace /O with /O2. The former is not documented for MSVC 5 - 8 and is unknown to MSVC 8. Remove /Gs and /Ge for MSVC 8. Stack checking is now always done.[doc/Make.htm 1.77, src/msvc32.mak 1.60, src/msvccmd.mak 1.20]
Added memory pointers to gsmalloc use by jpg2000 interface. DETAILS: Added jpx_memory to the stream state since the memory pointer in a normal stream object in often NULL indicating a stack object.[src/sjpx.c 1.10, src/sjpx.h 1.3, src/zfjpx.c 1.2]
When scaling factors of /ImageMatrix in a image mask for ImageType3 are negative, translation offset values for image mask rendering are incorrect and it makes abnormal output (eg. white lines). This patch fixes this bug #686843. Thanks to Len Sorensen for the analysis.[src/gximag3x.c 1.18]
When scaling factors of /ImageMatrix in a image mask for ImageType3 are negative, translation offset values for image mask rendering are incorrect and it makes abnormal output (eg. white lines). This patch fixes this bug #686843. Thanks to Len Sorensen for the analysis.[src/gximage3.c 1.14]
Fix bug 687038 that resulted in a crash if the initial device was not pdfwrite. DETAILS: This was almost fixed by recent changes to gs_pdfwr.ps and gs_setpd.ps for bugs 687325, 687436 and 687458. Unfourtunately, the initialization of parameters only occurred if the initial device was pdfwrite. A second patch removing the initial device constraint on the '1010' .schedule_init process was committed and fixes the problem. Note that there was a work-around that if -dPDFSETTINGS=... was given on the command line, it also worked. EXPECTED DIFFERENCES: none, since we don't test for this usage.[lib/gs_pdfwr.ps 1.39]
Added memory_t pointers to gs_malloc() gs_free() calls in devices that aren't normally built.[src/gdev3b1.c 1.5, src/gdevadmp.c 1.6, src/gdevccr.c 1.5, src/gdevcif.c 1.6, src/gdevcp50.c 1.6, src/gdevcslw.c 1.5, src/gdevhl7x.c 1.10, src/gdevimgn.c 1.7, src/gdevlp8k.c 1.5, src/gdevlxm.c 1.5, src/gdevmgr.c 1.6, src/gdevn533.c 1.6, src/gdevo182.c 1.6, src/gdevokii.c 1.7, src/gdevos2p.c 1.8, src/gdevp14.c 1.25, src/gdevphex.c 1.7, src/gdevpsdi.c 1.30, src/gdevsgi.c 1.6, src/gdevsj48.c 1.5, src/gdevsppr.c 1.8, src/gdevsunr.c 1.7, src/gdevwddb.c 1.7, src/gdevwprn.c 1.10, src/gp_macio.c 1.34]
fixed bug with iapi, removed gs_lib_finit()'s call of gs_malloc_release. DETAILS: The problem is that single instance and multi instance interfaces both call gs_to_exit() with different meanings. If gs_lib_init0 was called then it should malloc_release single instance exit library means free all. If the iapi interface was used then the memory should not be freed since gs_lib_finit() and gs_to_exit() are called when the interpreter is exited but there is a seperate delete_instance call that should free the memory[src/gsinit.c 1.7]
Fixed uninitialized fstdio2 pointer.[src/gslibctx.c 1.3]
Fixed incorrect function pointer prototype, const gs_memory_t * argument was missing.[src/gxfcache.h 1.26, src/gxfcopy.c 1.44]
Valid memory pointer used create a tile_clip device instead of NULL. Details : This needs to be leak checked.[src/gxp1fill.c 1.6]
Windows only: check_interrupts() with a mem pointer to access the poll function. DETAILS : This is windows specific since only windows uses the polling function in check_interrupts() macros. If the gs_dll interface is used then a single instance is forced since the design of that interface forces one thread per process. The iapi interface can not but enabled for more than one thread until the stream calling check_interrupts() calls are fixed. process_interrupts(NULL) calls are currently hacked to access a global memory pointer intended for access to stderr. This is a place holder until the stream object changed that guarantee a valid memory pointer in process_stream calls are committed. Basically it is common to allocate a stream object on the stack and use it in a functional manor with an uninitialized memory pointer in the object.[src/gdevdbit.c 1.11, src/gdevddrw.c 1.25, src/gdevwpr2.c 1.18, src/gdevwprn.c 1.9, src/gp_macpoll.c 1.2, src/gp_mslib.c 1.6, src/gp_mspol.c 1.5, src/gp_mswin.c 1.24, src/gxclrast.c 1.30, src/gxclread.c 1.11, src/gxclutil.c 1.11, src/gxdtfill.h 1.27, src/sfxfd.c 1.10, src/sfxstdio.c 1.9]
fixed typo in last commit.[src/gpcheck.h 1.8]
gs_memory_t pointer additions for msvc build. DETAILS : Mostly gs_malloc() and gs_free() additions of a gs_memory_t argument. Not gsdll.c forces a single instance.[src/gdev4081.c 1.6, src/gdev4693.c 1.9, src/gdev8510.c 1.7, src/gdevdm24.c 1.8, src/gdevdsp.c 1.25, src/gdevescp.c 1.7, src/gdevmswn.c 1.11, src/gdevmsxf.c 1.8, src/gdevpjet.c 1.7, src/gdevwpr2.c 1.17, src/gp_mspol.c 1.4, src/gpcheck.h 1.7, src/gsargs.c 1.9, src/gsdll.c 1.12, src/gsmisc.c 1.18, src/gxccache.c 1.32, src/gxclutil.c 1.10, src/imain.h 1.9, src/interp.c 1.19, src/main.h 1.7, src/msvc32.mak 1.59, src/sfxstdio.c 1.8]
Addition of a Library Context to start the process of removing globals. DETAILS : The goals is to remove globals from the system, this includes static globals that would hinder multiple threads from running at once. gs_lib_ctx is intended to be used as the opaque "handle" object that a client would use to associate with a thread running through the library. Independent of a gs or a language switch build, this needs a new iapi2.h that allows the use of better job control from the client side. gs_lib_ctx is stashed under the gs_memory_t object and all memory objects used by a thread refer to the same gs_lib_ctx. This storage location was choosen as a convenence since a memory_t pointer is common throughout the system. Most of the turmoil is adding memory_t pointers to functions that used global variables but didn't have a memory pointer. FILE stdin, stdout, stderr are one per process by default. stdin and stdout may be changed but stderr may not. FILE stderr is one per process and shouldn't be changed. Note the stderr_fn is also one per process, changing this function pointer will not help as most users of stderr printing do not have a thread handle. Changing to a thread local storage mechanism can solve this. gs_id's are currently per thread with each thread starting over at 1. This can be moved to per process with mutexes if so desired. A library context has a pointer to the top_of_system the intent is that this a void handle avaliable to make top of the system calls without knowing the data type. In a postscript only build this would be gs_main_instance but in a language switched build this would be an object above that main_universe. Other members of gs_lib_ctx_t are nothing more than global objects relocated to this "bag". gs_name_table, dict_autoexpand are examples of this. There are a few more globals that will be moved. At the moment iapi is still constrained to one thread, since some of the globals haven't been removed yet. The display device's callback function setting is supported for now but this interface should be changed to a sDEVICE style call. gs_memory_t is the base type the abstract type gs_raw_memory_t is gone, this means that all memory types must derive from gs_memory_t. In addition to a pointer to the gs_lib_ctx there is a pointer to a non_gc_memory this will always point to a non garbage collected memory, it maybe the current object or an object below the current gargabe collected memory space. This can be used were the previous code used the global gs_malloc_memory. gs_malloc() now takes a memory pointer, it finds the non-gc memory from a valid memory pointer and allocates from it. The gdevbit device has an improved algorthym for converting from cmyk to rgb, this is never used by postscript but for pcl rops it puts the k plane into rgb.[src/bfont.h 1.10, src/devs.mak 1.117, src/dstack.h 1.6, src/files.h 1.10, src/gdevbj10.c 1.9, src/gdevcdj.c 1.15, src/gdevdcrd.c 1.6, src/gdevepsc.c 1.11, src/gdevepsn.c 1.9, src/gdevijs.c 1.9, src/gdevp14.c 1.24, src/gdevpdfb.c 1.23, src/gdevpdfc.c 1.48, src/gdevpdfg.c 1.58, src/gdevpdfg.h 1.33, src/gdevpdfi.c 1.56, src/gdevpdfk.c 1.8, src/gdevpdfv.c 1.36, src/gdevpdti.c 1.36, src/gdevplnx.c 1.10, src/gdevprn.c 1.18, src/gdevprna.c 1.6, src/gdevpsdi.c 1.29, src/gdevpxat.h 1.6, src/gdevpxen.h 1.6, src/gdevstc.c 1.10, src/gdevupd.c 1.16, src/gdevvec.c 1.23, src/gdevxcmp.c 1.9, src/gdevxxf.c 1.9, src/gp_mac.c 1.16, src/gs.c 1.12, src/gs_dll_call.h 1.1, src/gsalloc.c 1.21, src/gsalloc.h 1.7, src/gsalphac.c 1.7, src/gsccode.h 1.13, src/gscdevn.c 1.21, src/gscolor.c 1.14, src/gscolor1.c 1.11, src/gscolor3.c 1.8, src/gscparam.c 1.10, src/gscpixel.c 1.12, src/gscpixel.h 1.6, src/gscrd.c 1.6, src/gscrd.h 1.7, src/gscscie.c 1.12, src/gscsepr.c 1.27, src/gscspace.c 1.17, src/gscspace.h 1.14, src/gsdevice.c 1.22, src/gsequivc.c 1.5, src/gsexit.h 1.10, src/gsfcid2.c 1.6, src/gsfcmap.c 1.24, src/gsfcmap1.c 1.7, src/gsfont.c 1.33, src/gsht.c 1.22, src/gsht1.c 1.15, src/gshtx.c 1.6, src/gsimage.c 1.12, src/gsinit.c 1.6, src/gsio.h 1.8, src/gsiodevs.c 1.6, src/gsistate.c 1.10, src/gslib.c 1.14, src/gslib.h 1.6, src/gslibctx.c 1.2, src/gslibctx.h 1.2, src/gsmalloc.c 1.12, src/gsmalloc.h 1.6, src/gsmemlok.c 1.6, src/gsmemory.c 1.9, src/gsmemory.h 1.8, src/gsmemraw.h 1.8, src/gsmemret.c 1.5, src/gsmisc.c 1.17, src/gsovrc.c 1.6, src/gspcolor.c 1.14, src/gsptype1.c 1.19, src/gsstate.c 1.24, src/gsstruct.h 1.18, src/gsstype.h 1.6, src/gsutil.c 1.10, src/gsutil.h 1.8, src/gxacpath.c 1.10, src/gxalloc.h 1.11, src/gxccache.c 1.31, src/gxccman.c 1.27, src/gxcht.c 1.13, src/gxclbits.c 1.9, src/gxclrast.c 1.29, src/gxclread.c 1.10, src/gxclrect.c 1.7, src/gxcpath.c 1.12, src/gxcspace.h 1.13, src/gxdevcli.h 1.34, src/gxdevice.h 1.19, src/gxdhtserial.c 1.5, src/gxfcmap.h 1.16, src/gxfcopy.c 1.43, src/gxht.c 1.16, src/gxht.h 1.9, src/gximag3x.c 1.17, src/gximage.c 1.7, src/gxpcmap.c 1.13, src/gxttfb.c 1.34, src/gzht.h 1.13, src/ialloc.c 1.7, src/ialloc.h 1.6, src/iapi.c 1.11, src/ibnum.c 1.8, src/ibnum.h 1.8, src/ichar.h 1.7, src/icharout.h 1.9, src/icid.h 1.8, src/icie.h 1.7, src/icstate.h 1.13, src/idebug.c 1.9, src/idebug.h 1.6, src/idict.c 1.11, src/idict.h 1.6, src/idparam.c 1.9, src/idparam.h 1.7, src/idstack.c 1.6, src/ifapi.h 1.19, src/ifont.h 1.14, src/ifont1.h 1.7, src/ifont42.h 1.9, src/igc.c 1.13, src/igc.h 1.8, src/igcref.c 1.6, src/iimage.h 1.7, src/iinit.c 1.10, src/ilocate.c 1.10, src/imain.c 1.39, src/imainarg.c 1.32, src/iminst.h 1.8, src/iname.h 1.5, src/interp.c 1.18, src/iparam.c 1.10, src/iplugin.c 1.5, src/iplugin.h 1.5, src/isave.c 1.11, src/isave.h 1.7, src/iscan.c 1.18, src/iscanbin.c 1.14, src/iutil.c 1.10, src/iutil.h 1.7, src/lib.mak 1.189, src/sdctc.c 1.5, src/std.h 1.12, src/szlibc.c 1.6, src/ttload.c 1.5, src/zarray.c 1.5, src/zbfont.c 1.27, src/zchar.c 1.14, src/zchar1.c 1.36, src/zcharout.c 1.12, src/zcharx.c 1.7, src/zcid.c 1.9, src/zcie.c 1.12, src/zcolor.c 1.19, src/zcontext.c 1.11, src/zcontrol.c 1.11, src/zcrd.c 1.8, src/zcsdevn.c 1.12, src/zcsindex.c 1.7, src/zcspixel.c 1.5, src/zcssepr.c 1.15, src/zdevice.c 1.9, src/zdevice2.c 1.9, src/zdict.c 1.6, src/zdps.c 1.8, src/zdps1.c 1.7, src/zfapi.c 1.52, src/zfcid0.c 1.22, src/zfcid1.c 1.19, src/zfcmap.c 1.15, src/zfile.c 1.41, src/zfileio.c 1.17, src/zfont.c 1.11, src/zfont0.c 1.7, src/zfont1.c 1.12, src/zfont2.c 1.7, src/zfont32.c 1.5, src/zfont42.c 1.20, src/zfontenum.c 1.4, src/zfrsd.c 1.10, src/zfunc.c 1.14, src/zfunc3.c 1.7, src/zfunc4.c 1.12, src/zgeneric.c 1.8, src/zgstate.c 1.10, src/zht2.c 1.12, src/zht2.h 1.3, src/zicc.c 1.7, src/zimage.c 1.14, src/zimage3.c 1.7, src/ziodevs.c 1.9, src/ziodevsc.c 1.7, src/zmatrix.c 1.8, src/zmedia2.c 1.16, src/zmisc.c 1.7, src/zmisc2.c 1.7, src/zmisc3.c 1.6, src/zpacked.c 1.6, src/zpcolor.c 1.15, src/zrelbit.c 1.6, src/zshade.c 1.15, src/zstring.c 1.6, src/ztoken.c 1.14, src/ztrans.c 1.22, src/ztype.c 1.8, src/zupath.c 1.10, src/zusparam.c 1.13, src/zvmem.c 1.8]

Fix : .OrigFont was not provided when an embeded font is defined. DETAILS : Bug 687598 "Courier CE font problems". The test case embeds a font with an instandard FontMatrix [ 0.00039 0 0 0.00039 0 0 ]. For passing it to pdfwrite, the procedure .completefont adds the /.OrigFont key to the font dictionary. However the key was added after .buildfont1 is called, and the device did not recieve the information at the time. This patch moves the .OrigFont setting ahead to the .buildfont* call. EXPECTED DIFFERENCES : None.[lib/gs_fonts.ps 1.47]
More work upon 687551 Implement the remaining TN 5044 procedures. This commit implements the setcmykoverprint procedure. DETAILS: We received a posting against 687551. This posting indicated that some files in arXiv.org were failing with the current version of Ghostscript but worked with older versions. The files were all created by a package called Canvas by Deneba Systems. They failed because setcmykoverprint was not defined. Evidently the people at Deneba Systems did not read the following comment from page 15 of TN 5044: "Note The setcmykoverprint operator has not been adopted by the industry. It remains on the list of color convention operators because it has some perceived usefulness, but it is not supported by any shipping host-based separation applications today." The even stranger detail is that the Deneba Systems people have a dummy version of this procedure that does not implement overprinting. Thus if they do not need overprinting, they have no need to use this procedure. The files also fail with Distiller 6.0, Illustrator CS, and Photoshop 6.0. However this change allows these files to work with current Ghostscript. The change consists of putting in a dummy version of the setcmykoverprint procedure. This version does not actually implement overprinting.[lib/gs_lev2.ps 1.32]

1. Fix (PS interpreter) : The FontBBox validation check was too strong. 2. Fix (pdfwrite) : Explicitely set line parameters in a charproc. DETAILS : Bug 687594 "Barcode Width". See comments in the new code. This solution is a partial one. With the current architecture of the Postscript interpreter, a device can't recognize whether a PS charproc sets line parameters or not. Therefore we copy to PDF the values, which appear at a first use within a charproc. The old code copied only values, which differ from defaults. The new behavior appears closer to Adobe Distiller. A complete solution should copy the PS behavior to PDF, i.e. the PDF charproc should set those and only those parameters, which are set by the PS charproc. For doing that we need flags in the graphic state structure per each graphic state parameter, reset all them before running a charproc, and set whenever a parameter is changed. Without the flag, when the charproc sets a value equal to the old one (which was inherited from the context of the glyph usage), the event of setting is lost and causes a line width and other problems. We don't want such a deep change now, and go with the partial solution, because the partial solution appears enough for customer's needs. Likely Adobe Distiller have same architectural problem, and resolves it in same manner.

Fix for 687572 AFPL Ghostscript 8.14 fails with some PDF files. DETAILS: The given file uses the scn operator inside of a form. The scn operator is used for defining a color with DeviceN color spaces. The scn operator uses .pdfcount (inside of scresolve) to determine the number of parameters. However inside a form, there is an extra dictionary on the stack. The fix consists of adjusting pdfemptycount (which is used by .pdfcount) to match the stack depth while executing a form. After the form is executed, pdfemptycount is returned to its previous value.[lib/pdf_draw.ps 1.83]

ps2write step 37 : Don't convert Type 1 into CFF when generating ps2write output. DETAILS : 1. Applied the Type 1 font writer. 2. Rather Type1C is a PDF 1.2 feature, we can't write it into a ps2write output. We use the OrderResources parameter to decide about (not)converting Type 1 into Type1C (i.e. into CFF), because we want to write some PDF1.2 objects into a ps2write output (for example - function objects, because we don't want to convert them in C code). 3. The parameter OrderResources isn't a good switch for deciding about CFF due to the parameter name, but currently we don't want to define one more parameter. Maybe will improve it later. 4.

Fix (pdfwrite) : Provide a delayed stream writing. DETAILS : The ps2write requires length of streams to be written before the stream. This implements pdf_begin_data_stream with opening a stream object in a temporary file, using a methgod similar to pdf_enter_substream.

Fix to pdfwrite initialization to make sure initial distiller params are incorporated into the device. Also add collection of distillerparams when building currentpagedevice. Fixes bugs 687325, 687436 and 687458. DETAILS: Earlier change to use .putdeviceparamsonly in gs_pdfwr.ps so that the use of setdistillerparams does not reinitialize the device caused the initial parameter settings to not be set in the device. The change to gs_pdfwr.ps accomplishes this. Part of the investigation by Igor Melichev discovered that the values of disillerparams would not be correctly reflected in the pagedevice. The change to gs_setpd.ps collects the currentdistillerparams when the device is pdfwrite and merges new values into the pagedevice dictionary. The method is similar to that used for the dynamicppkeys such as PageCount that can be changed by the device. For the distillerparams, the values are changed dynamically by setdistillerparams.

Fixes bug 687451 "default resolution for display device" Set the display resolution from the MS-Windows display resolution, using a device parameter -dDisplayResolution=DPI. DETAILS: The initial resolution must be set in display_put_params. Setting it in display_open is too late because this leaves the device resolution and currentpagedevice reporting different values. Callbacks can't be used in display_put_params because the callback structure is not yet initialized. This leaves a device parameter on the command line as the cleanest implementation. If HWResolution is set (e.g. from -r72), then use that. Otherwise, if DisplayResolution is set, use that in the initial display_put_params. After that, ignore all further use of DisplayResolution. The Windows client adds -dDisplayResolution=DPI to the command lines, similar to the existing -dDisplayFormat. The Windows client gets the resolution from the GDI. The default Windows display resolution is 96dpi (the same as the display device). This can be changed to 120dpi by selecting "large fonts", or other values in recent versions of Windows.[doc/Devices.htm 1.80, src/dwmain.c 1.18, src/dwmainc.c 1.20, src/gdevdsp.c 1.24, src/gdevdsp.h 1.9, src/gdevdsp2.h 1.8]
Fixes bug 687562 "vector devices close output file incorrectly". Vector devices open the output file with gx_device_open_output_file, so should close it with gx_device_close_output_file, not fclose.

In the Windows %printer% IODevice, the existing thread handle is closed automatically when the thread finishes. Duplicate the thread handle so we always have a valid handle for waiting and closing. DETAILS: When the thread finishes, the CRTL _endthread is closing the existing handle. During debugging, it was found that waiting on the thread handle was Ok because the thread was still running, but by the time CloseHandle ran the thread handle was invalid. IODevices are effectively static, so iodev->state is initialized once at the start of the interpreter. There is no need to test if iodev->state is valid.[src/gp_msprn.c 1.4]

The result is that the spot color is being displayed as black for the devices which handle spot colors and attempt to determine equivalent CMYK colors for the spot colors. These are the psdcmyk, tiffsep, and display (with -dDisplayFormat=16#a0800) devices. DETAILS: The Orange spot color is used in two different DeviceN color spaces. The first color space has components named 'None'. These components are used as part of a special feature described in section 4.5 of the PDF 1.5 spec. This feature uses the None components as a means for passing values to the color space's alternate tint transform function. In the example in the spec., these values are an equivalent color in the alternate color space. Our logic for determining an equivalent CMYK color for a spot colorant sets all color components except for the desired spot color to zero and then uses the tint transform function to form an alternate color. This results in the equivalent CMYK color being black since the None values contain the real information for the tint transform function. This change consists of check for the presence of DeviceN color space components named None. If any are detected then the equivalent CMYK color logic exits rather than determine an invalid color. This is sufficient for this case since the second color space which contains the Orange spot color does not have the None components. For the general case, a solution needs to be found which samples colors given actual values for the None components.[src/gsequivc.c 1.4]

Log Message: Fixes bug 686956 Display device does not support separations. Add support for separations to display device. This requires a change to the display callback structure. Support is maintained for clients using version 1 of the structure. DETAILS: Add support for a new color format, DISPLAY_COLORS_SEPARATION, which supports CMYK and spot colors. A new callback display_separation() is used to tell the client about the names and CMYK equivalents of each separation. The callback structure version number is incremented to 2 to show that has changed. The display devices checks whether it is passed the older v1 structure or the newer v2 structure, and only calls the new separation callback if it was given a v2 structure. Only 8-bit/pixel, up to 8 components and 64-bit depth are supported. In the Windows and gtk+ clients, a subset of these 8 separations can be selected for display.

Fix for 687553 rangecheck in .sethalftone5 and SeparationOrder. DETAILS: If a file specifies a type 5 halftone and the SeparationOrder device parameter is specified then a rangecheck can occur. This happens when the halftone includes two or more colorants that are not in the SeparationOrder parameter or one colorant and a 'Default' value. The problem occurs because the get_color_comp_index device procs use GX_DEVICE_COLOR_MAX_COMPONENTS to indicate colorants which are not being imaged due to the colorant not be included in the list for the SeparationOrder device parameter. However the gs_color_name_component_number routine was using the same value to indicate 'Default' halftones. The fix consists of modifying gs_color_name_component_number to look for GX_DEVICE_COLOR_MAX_COMPONENTS from the get_color_comp_index device proc. If found then the component is treated the same as a component that is not present in the device. The halftoning logic is only concerned with the colorants which are actually being used by the device.[src/gsht.c 1.20]

This change implements the enhancements described in 542629 CMYK tiff driver and 687440 Support for outputting PDF separations separately. This change implements three devices: tiffgray which produces an 8 bit gray output with uncompressed data, tiff32nc which produces 32 bit CMYK with uncompressed data, and tiffsep which produces a tiffgray file for each separation (CMYK and spot colors) and it also produces a CMYK output file which is created using the CMYK image data plus the spot colors image data. The spot colors are converted to CMYK using the logic in 687431. DETAILS: This change requires that 687504 be included in the sources. The tiffgray and tiff32nc devices are logically similar to the tiff24nc device except for the use of gray and CMYK process color models. The tiffsep device uses much of the logic which has been created for the psdcmyk and spotcmyk devices. These include logic for implementing the SeparationOrder setpagedevice parameter 687423, logic for determining an equivalent CMYK color to spot colors 687431, and automatically detecting spot colors (without requiring that they be specified via the SeparationColorNames setpagedevice parameter 687504. The tiffsep device also prints the names of any spot colors detected within a document to stderr. (stderr is also use for the output from the bbox device.) For each spot color the name of the color is printed preceded by '%%SeparationName: '. This provides a mechanism for external applications to be informed about the names of spot colors with a document. Due to the 64 bit pixel size limitation, the tiffsep can handle a maximum of 8 colorants per pass. However it is possible to handle more than 8 colorants by doing multiple passes. For each pass after the first one, the names of all of the separations need to be specified via the SeparationColorNames parameter and the names of the desired separations need to be specified via the SeparationOrder parameter. When colorants are selected via the SeparationOrder parameter, the composite CMYK output contains the equivalent CMYK data only from the selected colorants. It is possible to create an overall CMYK composite for more than 8 colorants by then adding together (via an external application like imagemagick) the composite CMYK output files from the individual Ghostscript passes. Internally each spot color is assigned a spot color number. These numbers start with 0 for the first spot color. The spot color numbers are assigned in the same order as the names are printed to stderr (see above). This order also matches the ordering in the SeparationColorNames list, if this parameter is specified. The spot color numbers are not affected by the SeparationOrder parameter. This device creates multiple output files. The file specified via the OutputFile command line parameter is used to contain the composite CMYK equivalent. File names for the separations for the CMYK planes are created by appending '.Cyan.tif', '.Magenta.tif' '.Yellow.tif' or '.Black.tif' to the to the end of the file name specified via the OutputFile parameter. File names for the spot color separation files are created by appending '.sn.tif' (where n is the spot color number) to the end of the file name specified via the OutputFile parameter. The src/gdevtsep.c source file does have a compile time option for including/not the '.tif' at the end of the created file name. It also has a compile time option for using the name of the spot color as part of the file name. However this is not enabled since there may be conflicts with spot color names (in which Adobe allows almost anything) and the operating system's conventions on file naming. This change consists of the new source module src/gdevtsep.c, changes to devs.mak for defining the new devices, changes to the various top level make files for including these devices in their DEVICE_DEVS definitions, and changes to the documentation files.[doc/Devices.htm 1.78, src/Makefile.in 1.36, src/devs.mak 1.115, src/dvx-gcc.mak 1.26, src/gdevdevn.h 1.9, src/gsdparam.c 1.15, src/macos-mcp.mak 1.25, src/msvc32.mak 1.58, src/openvms.mak 1.36, src/os2.mak 1.37, src/unix-gcc.mak 1.45, src/unixansi.mak 1.36, src/watcw32.mak 1.29]

Fix for 687534 Unable to determine equivalent CMYK for spot colors that are only used with overprint. DETAILS: The given test file uses spot colors. However the psdcmyk device was creating output files which did not contain equivalent CMYK colors for the spot colors. The cause was that the previous version of the logic was capturing the equivalent CMYK colors when the psdcmyk device's high drawing procs were called. However if overprinting is enabled, then the overprint device was inserting its own versions of these routines. Since it only took one call to a high level drawing handler, the previous logic would capture the equivalent CMYK colors if there were any drawing operations with a spot color that did not have overprinting enabled. The fix consists of moving the capturing of the equivalent CMYK colors to a new device proc. This new device proc is called update_spot_equivalent_colors. This device proc is called whenever a Separation or a DeviceN color space is installed. The default version of the proc does nothing. Thus there is only a small amount of overhead added for the installation of Separation and DeviceN color spaces for devices which do not need the equivalent CMYK colors for spot colors. Most of the change consists of the standard details of adding a new device proc. There are several places that have to be updated when this is done. The documentation in doc/Drivers.htm was updated to include this new proc. The high level drawing handlers in the psdcmyk devices were removed and a new psd_update_spot_equivalent_colors procedure was added. Some minor changes were made in the logic in gsequivc.c since it is no longer necessary to scan through base and alternate color spaces looking for Separation and DeviceN color spaces. The comments at the beginning of gsequivc.c was changed to reflect the changes in the logic for capturing equivalent CMYK colors for spot colors.[doc/Drivers.htm 1.47, src/gdevbbox.c 1.18, src/gdevdflt.c 1.24, src/gdevnfwd.c 1.24, src/gdevprn.c 1.17, src/gdevpsd.c 1.15, src/gdevrops.c 1.12, src/gscdevn.c 1.18, src/gscsepr.c 1.25, src/gsequivc.c 1.3, src/gsequivc.h 1.2, src/gxclip.c 1.15, src/gxclip2.c 1.11, src/gxclipm.c 1.13, src/gxclist.c 1.14, src/gxdevcli.h 1.33, src/gxdevice.h 1.18]

Note: Spot colors are only supported on a few devices which have output file formats which allow for spot colors. These are currently the psdcmyk, spotcmyk, and xcfcmyk devices. This commit only implements this feature on the psdcmyk, spotcmyk and devicen devices. In order to implement this feature, a device needs to be able to allocate image buffer memory for each colorant and to detect when a new colorant is being used inside of a color space. The implementation has the following pieces: 1. The handling of the MaxSeparation setpagedevice parameter was extended. Previously this parameter was always set to one. For most devices it now indicates the number of colorants being used by the device. For most devices this is a fixed quantity, however for the psdcmyk device, this parameter can be used to tell the device to allocate image buffer memory for up to eight colorants. (The eight colorant limit is due to the fact that the psdcmyk device uses 8 bits per colorant and we currently have a 64 bit maximum pixel size.) 2. The devices already have a 'get_color_comp_index' routine which is used to query if a colorant is supported by the device. However this routine is used for both real components in color spaces and also for some special cases. For instance, the same halftone may be used either for a cyan or a red colorant. To handle this case, the halftoning setup logic will query the get_color_comp_index routine to check if cyan is supported by the device. If not then a query is made to see if the device supports red. By monitoring the names of the components passed to get_color_comp_index routine, a device can detect when a new spot color is being used. However it is necessary to be able to detect the special cases so that the device does not believe that it has a 'red' spot color. To do this the third parameter of the get_color_comp_index device proc was logically modified to indicate if a name represents a name actually in a color space or one of the special case situations. Previously this parameter was not being used. 3. The get_color_comp_index routine for the psdcmyk device was modified to look for new spot colors and to add then to its list of colorants if there was space available. Note: This also required that the psdcmyk device have its own structure descriptor, pointer enumeration and relocation procedures. The macro which was used to define the psdcmyk and psdrgb devices needed to be changed since the previous macro used the st_device_printer structure descriptor instead of the new structure descriptor for the psd devices.[src/gdevdevn.c 1.20, src/gdevdevn.h 1.8, src/gdevnfwd.c 1.23, src/gdevperm.c 1.4, src/gdevpsd.c 1.14, src/gdevxcf.c 1.8, src/gscdevn.c 1.17, src/gscsepr.c 1.24, src/gscspace.c 1.16, src/gsdparam.c 1.14, src/gsht.c 1.19, src/gxcmap.c 1.21, src/gxcmap.h 1.9]

Randomization parameters for cff_string_index were computed wrongly, causing the search to skip some items. As a consequence, some strings were added to the table many times, causing a groth of the table while CFF size estimation iterations, and psf_write_type2_font returned error due to "offset > End_offset". 2.

(pdfwrite) : Implementing a dynamic recongnition for Type 3 charproc variations (continued 4). DETAILS : Recent changes about charproc variations caused an appearence of idle entries in the xref table. Those entries pointed to zero length objects and were never referred. Idle entries appeared due to the substream accumulator reserved an object id before entering a substream, but later the object (a charproc) was cancelled. This patch delays the reservation of an object id until we decide that the object won't be cancelled. Added a new argument of pdf_enter_substream for this purpose.

Fix (type 1 hinter) : 1. Ever align the Y-coordinate of a glyph origin to pixels. 2. Improve the unaligned pole interpolation; 3. Set a waeaker angle threshold in t1_hinter__is_stem_hint_applicable. 4. Allow an offset fuzz in t1_hinter__is_stem_hint_applicable. 5. Align upper/lower horizontal stems by the upper/lower edge. 6. A dependency was missed in lib.mak . DETAILS : Bug 687419 "poor font rendering on X11 with gs 8.14". The intention of this change is to improve the rendering quality with TextAlphaBits > 1, but actually it modifies glyph rendering in all cases. 1. The test file of the bug 687419 shows that we had 3 inconsistent requirements : - the analigned glyph origin; - uniform glyph size; - and contrast stems. Since an uniform glyph height looks critical, we drop the analygned Y-coordinate of the glyph origin. In other words, now we ever align the Y-coordinate of the glyph origin to pixels. This also reduces the number of glyph raster variants in the cache. 2. The old interpolation algorithm could cause significant distortions with flex-like serifs, which are not marked with flex. The character 'L' in the test document of the bug 687419 demonstrates that. If the path goes outside the interpolation interval and have no turns, now we shift the "outer" parts rather than breaking the path at extremal poles. (We wanted this change a long ago but haven't got a strong reason for it.) 3. The threshold in t1_hinter__is_stem_hint_applicable changed from 1/3 to 9/10. This makes more stems to recognize. The reason for that is the same character "L". 4. Allowed a blue_fuzz offset t1_hinter__is_stem_hint_applicable. Debugged with comparefiles/tpc2.ps . 5. In the test file of the bug 687419 the small font has no upper alignment zone for lowercase. This caused an uniform glyph height due to wide and norrow horizontal stems aligned ocasionally by top or bottom. Implemented a choice of the aligned edge depending on the Y-coordinate of stem middle relative to the glyph middle. 6. gxhintn_h was defined in lib.mak after it is used at once. EXPECTED DIFFERENCES : Almost all comparefiles render differently.[src/gxchar.c 1.43, src/gxhintn.c 1.49, src/lib.mak 1.185, src/gxhintn.h 1.20]

Now we represent ExtGState objects as cos_dict_t instances, and perform a full comparizon before writing them into the output PDF. Redundant equal objects are being substituted and skipped. This patch consists of 4 parts : 1. Creting an ExtGstate object, replaced old calls to stream functions with calls to cos_dict_t functions. 2. Implemented the comparizon/substitution logic in pdf_end_gstate. 3. pdf_prepare_drawing now doesn't pass keys to pdf_update_halftone, pdf_update_transfer, pdf_write_transfer_map, because we don't want them to become a part of a value. Instead that we made them to be keys of the cos_dict_t instance. 4. Defined new functions cos_dict_put_c_key_bool and cos_dict_put_string_copy to simplify the new code.

Fix for 687477 Bad incremental update to a PDF file. DETAILS: The given test file had a bad incremental update. This update has two problems: 1. The trailer dict only had a Prev entry. None of the required entries were present. To fix this problem, entries from previous trailer dicts are placed into the initial trailer dict if there is no entry with the same key in the initial trailer dict. 2. The update had an xref table with two entries. One of them was bad. (Not a very good percentage.) To fix this problem, all entries in the composite xref table are scanned to verify that they point to a valid objects. If not then the rebuild logic is used to attempt to recover the xref data. This can be disabled by adding -dNoVerifyXref to the command line. In most cases, the verification time is not noticeable but I did find a file with 104,000 xref entries and it took about 2 seconds to verify the xref table.[lib/pdf_base.ps 1.43, lib/pdf_main.ps 1.87, lib/pdf_rbld.ps 1.7]

High level devices may need a device color while executing stringwidth. DETAILS : This is second step of fixing the bug 687489 "pdfwrite creates invalid Type3 font -- missing characters". The problem happens due to the old code could run a charproc while executing a stringwidth, when device color is not evaluated. This patch provides the device color loading with no dependence on the text operation. dev_proc(dev, text_begin) now receives a device color in any case.

(pdfwrite) : Implementing a dynamic recongnition for Type 3 charproc variations (continued). DETAILS : This is a preparation for fixing the bug 687489 "pdfwrite creates invalid Type3 font -- missing characters". The problem happens due to the old code could run a charproc while executing a stringwidth, when the PDF viewer state isn't syncronized with the PS graphic state. We don't synchronize in this case because stringwidth doesn't paint. Our intention is to know whether a charproc changes graphic state parameters : current color, line width, etc. For doing so we need (1) to save the viewer state in the viewer state stack, and then (2) synchronize with the PS graphic state without writing commands to the PDF. This patch does provide (1) but does not implement (2) because we want to check the change (1) for no regressions. The change (2) will be a separate step. Saving a viewer state in a stack when entering a charproc was contributed with the recent patch http://www.ghostscript.com/pipermail/gs-cvs/2004-May/004507.html as an improvement of pdf_enter_substream, which was called from pdf_install_charproc_accum called from pdf_text_set_cache. In other words, the viewer state saving was deferred until setcachedevice/setcharwidth. However we need to save the viewer state in the beginning of a PS charproc. This patch moves the call to pdf_enter_substream from pdf_install_charproc_accum to the TEXT_PROCESS_RENDER branch of pdf_text_process. We believe that the new logic is more straight : we start the charproc stream accumulation immediately before the PS interpreter enters a charproc interpretation. Minor changes : 1. Defined pdf_start_charproc_accum as a symmetric one for pdf_end_charproc_accum. 2. Renamed pdf_install_charproc_accum into pdf_set_charproc_attrs. 3. Improved the argument list of pdf_prepare_text_drawing. EXPECTED DIFFERENCES : None.[src/gdevpdti.c 1.30, src/gdevpdfx.h 1.90, src/gdevpdtt.c 1.80]

This is an beta release of the development tree. It contains numerous new features and is made available for those interested in testing out the new version before it becomes the next stable release.
New features in this version :
Topological grid fitting, an original method developed for Ghostscript by Dr. Igor V. Melichev, improves the rendering of True Type fonts at small resolutions. See the documentation for GridFitTT for information on this feature.
The PDF writer now implements PDF 1.4 encryption. See the encryption parameter documentation for more information.
A new rendering method for shadings, developed for Ghostscript by Dr. Igor V. Melichev, improves the quality and performance of rasterization on continuous tone devices. The new method allows hardware or software acceleration with help of customizable routines for filling areas with a linearly varying color. functions.
This version contains the first release of Rinkj, an experimental new driver for some inkjet printers using ETS screening. See the Rinkj section for more information.
We now support PDF 1.5 files, including the new compression and encryption modes.
We have beta support for Jpeg2000 compressed images, using the JasPer compression library. This is only enabled as part of the default build in the autoconf (POSIX) build system in this release.

(pdfwrite) : 1. Implementing a dynamic recongnition for Type 3 charproc variations; 2. Bug : Viewer state could desynchronize when entering a charproc accumulation. DETAILS : Bug 687472 "barcode wrongly converted to type3 font". Type 3 glyph variations may appear if BuildChar uses setcharwidth. If a charproc uses setcharwidth, we perform the charproc accumulation for each character occurance, and compare the accumulated stream with older ones if they exist. In the case of exact equality (including the character name and character code), the old charproc is used. Othervise we embed a new one. If the character code was used with another charproc, we create another PDF font to resolve the conflict. Thus a single PS Type 3 font may convert into several PDF Type 3 fonts, and the text may be broken into smaller pieces. Particularly this happens with the test file of the bug 687472. Viewers must account that implementing the text serchability. A new array pdfont->u.simple.s.type3.cached is used to remember whether a charproc uses setcachedevice[2]. If a character used it at ones, we assume that all further its occurances to do same. We think that this assumption is implied by PLRM. Viewer state was not saved when entering a charproc accumulation, and was not restored after exiting it (a bug). This could cause wrong object attributes and excessive commands written into PDF. This patch fixes that. Some PDFs become longer due to excessive ExtGState objects generated for dropped copies of charprocs. Opened a new bug 687487 for tracking this issue.

Handle some errors that could halt the regression run. DETAILS: When running a raster comparison, the test case generates a ShortDescription that includes the modification date of the baseline raster date. If no such file exists, the baseline gs is run to create an entry. However, if that insertion attempt fails, there is no baseline raster for reference. While the test case itself handled this properly, the ShortDescription logic did not, throwing an error that terminated the whole run. Also, makesum was returning '0' instead of None on failure, which was incompatible with the use of its return value as a dbm key. It now returns None in that case, and when it cannot stat the file argument at all.[toolbin/tests/gscheck_raster.py 1.11, toolbin/tests/gssum.py 1.7]
Fix reference count of overprint compositor so that it doesn't get freed too early. Fixes SEGV of bug #687425 for customer #1110. DETAILS: This only showed up when banding was being used. This only showed up when a high level image was being rendered from the clist since this installed a 'clipper' device on top of the overprint compositor. When the clipper device was closed, the finalization proc decremented the reference count for the 'target' device of the clipper which was the overprint compositor. When the overprint reference count was decremented to 0, it was freed even though it was being used by the clist renderer. EXPECTED DIFFERENCES: None.[src/gxclrast.c 1.28]

Log message: Revised fix for 687418 WTS does not work with bitcmyk driver. DETAILS: The changes in this revised fix are pretty extensive. Note: This patch includes several items from Russell Lang. I am including these since they are required for the proper execution of the patch and it does not seem reasonable to require possible testers or reviewers to have to track down and install these patches separately. The list of changes includes: 1. Added logic to check_device_separable to also set the gray_index value. This suggestion came from Russell Lang. 2. Add verification that a colorants bits are consecutive. (from Russell Lang in: http://www.ghostscript.com/pipermail/gs-code-review/2004-May/004501.html 3. Changes to gx_default_encode_color and gx_default_decode_color to use position and bit count info from the device's color_info data. (Also from Russell Lang in the previously mentioned submission.) (See the comments in item 21 below about the gx_default_decode_color routine.) 4. Included test routines. (Also from Russell Lang in the previously mentioned submission.) 5. Added calls to check_device_separable prior to calls to the various 'fill_in_procs' routines (gx_device_fill_in_procs, gx_forward_fill_in_procs, fill_in_procs). The fill_in_procs routines use the separable information in choosing default routines for the encode_color and decode_color routines. Thus we have a chicken and egg problem since check_device_separable also uses the device's encode_color routine. The test routines from Russell were a great help in debugging Also various changes that were found while testing this patch: 6. The various color deskjet drivers (gdevcdj.c) was incorrectly setting the dither_grays and dither_colors values to 5 instead of 256. (I have no idea why.) The max_gray and max_color values were set to being set correctly to 255. 7. The color deskjet devices (gdevcdj.c) were doing BG and UCR removal inside of the encode_color routines. These devices use the default color_mapping_procs which also do these tasks. The code in the encode_color_routine was removed since it could cause conflicts with the overprint routines. The code in the encode_color routine was also using a fixed BG/UCR logic (from PS level 2). 8. Corrected a problem in the color desk jet decode_color routine which was always returning zero for the black value. 9. Changed the casting for values assigned to the std_colorant_names field. Note: MSVC and gcc complain about different conditions. There does not seem to be a combination that will keep both happy. This set produces no complaints from gcc. 10. Corrected the setting of dither_grays and dither_colors for the devicen device. Previously this was being set to 1 when it should have been set to 256. Found by Russell Lang. 11. Modified check_device_separable to only check for appropriate values of the max_gray/dither_grays and max_color/dither_colors pairs only for gray/color devices. 12. Added check for encode_color routines which encode zero bits for a colorant. Previously this condition would have caused an infinitely in check_device_separable. Change suggested by Russell Lang. 13. Removed a previous call to set_linear_color_bits_mask_shift in gx_default_fill_in_procs. This has been logically replaced by the calls to check_device_separable which have been added. 14. Corrected a problem in the ppm_map_rgb_color in gdevpbm.c. This routine was calling gx_default_encode_color which requires 15. Corrected problem in pcx256 device which incorrectly setting the dither_grays and dither_colors values. 16. Removed the check_process_color_names routine from gdevpsd.c since it not used. 17. Modified the dci_alpha_values macro in gxdevcli.h. This macro was setting some devices as 'separable' but was not setting the related color_info fields (comp_shift, comp_bits, comp_mask). Now this macro sets a devices as 'unknown'. The check_device_separable routine will change this for devices which are separable. Devices which want to change their process color model need to either set themselves as 'unknown' and let check_device_separable handle things or else the device needs to setup its own values for separable color_info fields. 18. Added a call to check_device_separable into gdev_x_open in gdevxini.c. With this addition, the x11 device is detected as being sperable. This is need since the x11 device sets up a color map in gdev_x_open. Prior to this, the encode_color routine for he x11 device returns 0 regardless of its input. 19. Modified the uniprint device (gdevupd.c) and color laser jet devices (gdevcljc.) to use 256 instead of 5 for its dither_gray and dither_color values with devices that have 8 bits per colorant. This is appropriate since the the max_gray and max_color values are 255. (I do not know why these values were being set to 5. This same error was found in gdevcdj.c. My only guess is that it was a typo in gdevcdj.c. Since this device is recommended as an example of how to code a color raster device (in Devices.htm), the error was propogated into the other devices. 20. Added more comments to gxdevcli.h explaining the use of the gray_index, max_gray, dither_grays, max_color, and dither_colors fields in the device color_info structure. 21. Changed the gx_default_decode_color routine (again). Russell Lang created two revisions to this routine as part of his efforts on this task. However one version was slow but produced the desired results. The second version was faster but its output was slightly different. This revision produces the same output as the first version but does so without the while loops that slowed its operation. Note: There is another related submission from Russell Lang that is not included in this patch. This consists of changes to the display device for making it 'separable'. This change is needed for Igor's linear shading work. http://www.ghostscript.com/pipermail/gs-code-review/2004-May/004500.html[src/gdevcdj.c 1.14, src/gdevcljc.c 1.7, src/gdevcmap.c 1.6, src/gdevdevn.c 1.17, src/gdevdevn.h 1.5, src/gdevdflt.c 1.23, src/gdevdsp.c 1.21, src/gdevmem.c 1.8, src/gdevp14.c 1.23, src/gdevp2up.c 1.6, src/gdevpbm.c 1.11, src/gdevpcx.c 1.7, src/gdevplnx.c 1.9, src/gdevpnga.c 1.9, src/gdevprn.c 1.15, src/gdevpsd.c 1.11, src/gdevrops.c 1.11, src/gdevupd.c 1.15, src/gdevxalt.c 1.11, src/gdevxcf.c 1.7, src/gdevxini.c 1.14, src/gsdevice.c 1.21, src/gslib.c 1.13, src/gxcmap.c 1.20, src/gxdevcli.h 1.32, src/gximag3x.c 1.16, src/gximage3.c 1.13, src/gxpcmap.c 1.12, src/zcolor.c 1.18, doc/Language.htm 1.85]

DETAILS : Debugged with the test file of the bug 687464 "Problem converting from PS to PDF. 2 latin characters did not convert properly." : different PDFs generated with URW fonts and with Soft Horizon fonts rather none of them were embeded. The old code did not add a glyph to Encoding if the PS font has no glyph defined. Due to that, if the source encoding uses an instand glyph, the instandard glyph was not written to Differences, causing a standard glyph erroneusely appeared instead the instandard glyph.

Apply a recursive 'configure' step to the autoconf build to generate required code for the jasper library. DETAILS: The jasper library also ships with an autoconf build framework for POSIX systems. Unfortunately, it relies on this framework to generate a header file with defines describing the local system. This header, located in jasper/src/libjasper/include/jas_config.h can be generated by hand from the jas_config.h.in template, but it must be available when we're directly compiling the source as part of Ghostscript. We could attempt to construct one of our own, but within the confines of an autoconf build, using jasper's native configure is more robust. We could also go ahead and use recursive make to build the library natively, but we would need a static makefile for non-autoconf builds. Jasper provides an alternate header, jas_config2.h for use with MSVC.[src/configure.ac 1.46]
Add the jasper include path when compiling the JPXDecode filter so the headers can be found if they're not already installed on the system. Required to compile in the jasper library source from a fresh distribution of the third-party library.[src/int.mak 1.126, src/lib.mak 1.182]

A new implementation of shadings, step 73. DETAILS : The new code is disabled with NEW_RADIAL_SHADINGS in gxshade4.h . The old implementation of the radial shading extensions appears incompatible with the tensor representation of the radial shading due to different spatial subdivision. Collisions at extension boundaries caused dropouts. Besides that, the old implementation can't handle the case in which circles contact each another and one circle is inside another. Also we suspect that with the old implementation the trailing extension can overlap the shading when represented as "triangles". This patch implements extensions with tensor patches. Rather they have a constant color, we need the wedge logics to work with them. Also we reworked the analyzis of special cases of mutual placement of the base circles. The new code works, but there are known problems : 1. Extensions to be tested systematically. 2. Debug mesh_padding and wedges with zero length sides. 3. Skip painting outside the clipping area. 4. Optimize for constant color. 5. Why "STEUER-RollingMesh 2(radial).ai-.pdf" generates so many triangles ? 6. Outer wedges may break the order of painting.

A new implementation of shadings, step 64. DETAILS : The new code is disabled with USE_LINEAR_COLOR_PROCS in gxshade4.h . Fixing various problems with linear color : 1. Clipping didn't work with linear color. 2. gx_default_fill_linear_color_scanline missed some clipping by X. 3. Zero smoothness caused an infinite recursion. 4.

Limit the number of timing runs we're willing to do to detect the cache size, preventing an infinite loop if the os timing calls never measure appreciable elapsed time. After a patch from Patrick TJ McPhee. Bug 687095. DETAILS: It looks like there's a bug in some versions of FreeBSD which cause time_clear() to always return 0, even though the loop is being run. This is clearly incorrect behaviour of clock() on these systems, or the user is mistaken in debugging the problem, since we've been unable to reproduce. But in either case our code is arguably wrong. The later measurements will obviously not detect a nonlinearity if the timing loop continues to return 0. However, they will terminate at MAX_BLOCK (4MB) and so the misdetection isn't egregious. It was only the estimation of the measurement error that could loop forever.[src/genarch.c 1.9]
Make check_device_separable private to avoid a warning from gcc.[src/gdevdflt.c 1.20]
Fix for 687455. The overprint logic creates a temporary device which is used to initialize a set of procedures. This temp device is only paritally initialized. The partially initialized device is being set up as a forwarding device but the target device is not yet present. This created a problem when check_device_separable executed. This change sets the temp device to 'not separable' so check_device_separable does not try to do anything.[src/gsovrc.c 1.5]

A new implementation of shadings, step 63. DETAILS : The new code is disabled with USE_LINEAR_COLOR_PROCS in gxshade4.h . Fixing various problems with linear color : 1. Applyed compiler independent data types int32_t. 2. Implemented ends_from_fa with X-independent gradients, because the decomposiotion by color linearity breaks at coordinates which are not trapezoid corners. Added a comment to gxdevcli.h to document it. 3. X-gradient denominator was wrong. 4. X-gradient numerator left wrong from the step 58. 5. gx_default_fill_linear_color_scanline ignored the clipping by X. 6. A_fill_region missed the path bbox. 7. Implemented is_color_linear for a proper subdivision by color. 8. decompose_linear_color now applies a linear color instead fill_triangle_wedge. See a comment in fill_triangle_wedge. Also for mesh_padding. EXPECTED DIFFERENCES : None.[src/gdevddrw.c 1.24, src/gdevdsha.c 1.8, src/gdevnfwd.c 1.22, src/gxdevcli.h 1.31, src/gxdtfill.h 1.25, src/gxshade1.c 1.28, src/gxshade6.c 1.61]

Fix for 687418 WTS does not work with bitcmyk driver. This fix is applicable to most devices. DETAILS: WTS screening, overprinting, halftoning for more than five colorants and the fast halftoning logic need to be able to create gx_color_index values without using the encode_color routine. This only works if a device is 'separable'. However, by default, most devices indicate 'unknown'. This change implements a heuristic for checking if a device is separable. If so then it also determines the various related parameter values (comp_shift, comp_bits, comp_mask).[src/gdevdflt.c 1.19]

Implement 687423 Implement SeparationOrder for psdcmyk device. DETAILS: The following changes are for implementing the SeparationOrder parameter for the psdcmyk device. The change consists of the following: 1. Several routines which were duplicated in the spotcmyk and psdcmyk devices were restructured to allow the use of common subroutines. As part of this effort the various common DeviceN related parameters were separated into a substructure (call devn_params). This allows the use of common routines even though the devices do not have the same overall device description structure. 2. Changes to the src/gdevpsd.c module for actually collecting the SeparationOrder parameter data and then using it. Note: The treatment of separations is different for the process color model colorants versus the spot colors. The colorants for the process color model do not have their order changed. The output file always starts with information for the CMYK channels. If one of these colorants is not specified in the SeparationOrder, then the output channel data in the file will simply be 'blank'. Spot colors follow CMYK data. They are rearranged. Only the spot colors specified are output. 3. Several checks in src/gdevdflt.c and src/gxcmap.c had to be removed or modified. These checks were assuming that a device with a single component uses a gray process color model and a device with three components used RGB.[src/gdevdevn.c 1.15, src/gdevdevn.h 1.3, src/gdevdflt.c 1.18, src/gdevpsd.c 1.8, src/gsdparam.c 1.13]

Fix to make sure that both stroke (CA) and non-stroke (ca) opacity is set. Support for customer #32 that wants to create transparent effects in PDF from PostScript input. DETAILS: Previously the opacity was set for one or the other (whichever was first) and only updated when the value changed. Since the 'state' only retained a single value, the following PS snippet would not set the CA value as it should to 0.5. Since we never use the 'b/B' fill + stroke painting methods (our graphics library currently has no device function for this), a PDF that contains a 'b' method will be decomposed into a 'f' followed by 's' operation, setting the opacity from the PDF interpreter's retained ca/CA between the operations.

Fix 687189 for bbox_forward_add_rect infinite recursion. This problem caused segment faults or apparent hangs with the x11alpha device. This fix also works for 656414 segfault when using x11alpha DETAILS: The problem was due to the bounding box device creating more and more bounding box devices in the device chain when the overprint compositor was being used. The x11alpha device uses the bounding box device. The overprint logic uses the 'create compositor' logic when a change is made in the status of the overprint or overprint mode parameters. However a new compositor is not created each time. Instead the overprint device simply updates its parameters. The bounding box device has its own create compositor. This routine would call its target device's create compositor routine and then wraps a new bounding box device around the target's compositor. The combination of many create compositor calls from the overprint logic and the fact that the bounding box device adds a new bounding box device could result in hundreds of bounding devices in the chain. The fix consists of checking if the bounding box's target device actually created a new compositor device. Only when a new compositor was added is a new bounding box also added to the chain.[src/gdevbbox.c 1.16]
Fix for 687402 Missing color on annots.pdf. This is actually not an error. Instead it is due to some confusion about the displaying of link annotations. DETAILS: To prevent confusion, the following two paragraphs of explanation were added to the first page of the examples/annots.pdf example file. "IMPORTANT NOTE ABOUT THIS PAGE: This page was created for the testing the display of link annotation parameters. The file was created using Adobe Acrobat 5.0 (and modified using Acrobat 6.0). The displaying of each annotation is specified in the annotation. By default, Acrobat sets link annotations so that they are normally displayed by 'viewer' applications. They are not normally displayed in printed output. That is the case with these annotations. Ghostscript checks the display specifications for each annotation. By default, Ghostscript assumes that the output is 'printed' if the 'OutputFile' parameter is defined. Adding '-dPrinted=false' to the command line will force Ghostscript to display 'viewer' annotations in all output. Adding '-dPrinted=true' will disable the displaying of these annotations."[examples/annots.pdf 1.2]
Handle (yet another) invalid PDF that Adobe Acrobat can open. If the Font /Subtype is / then assume Type1. Also issue a **** WARNING message. Bug #687422 for Artifex customer #670.

Fix : MSVC6 compiler warnings. DETAILS : An "initialized data" warning appeared when MSVC6 performs a release build with inline optimizations on (The inline optimization inlines small function bodies, being not marked with the inline keyword). 1. The "uninitialized data" warning in alloc_name_index_is_since_save in isave.c was a real bug with an indeterministic behavior : nref.tas.rsize was accessed by names_index_inline from names_string_inline from alloc_name_is_since_save from alloc_name_index_is_since_save with no advance initialization. This bug was not detected because this function is only invoked when a 'save' unwinds glyph names added to an incremental font, but doesn't unwind the font - we have no such examples. IMO existing PS drivers never cvreate such documents. 2. The "uninitialized data" warning in cos_array_add_object appears due to cos_copy_element_value copies entire 'value' when another variant of an union has a bigger size and was uninitialized. The copying of the uninitialized data looks not harmful due to the 'int' type, but generally it could cause an interrupt on platforms with a tagged memory. We prefer to suppress the warning with an unuseful initialization, because the processor time consumption is pretty small and happens not frequently.

Fix : setcachedevice must not depend on a BuildChar color and on gx_show_text_retry. DETAILS : 1. The bug 687391 "assert src/gxccman.c:557 again" happened because BuildChar changed the current color before setcachedevice calls compute_glyph_raster_params, and the raster params computed differently than during the advance glyph raster cache lookup. 2. Removed if (pgs->in_cachedevice) return_error(gs_error_undefined); from gs_setcolor, because I can't guess it's reason/purpose. It looks as a rudiment from a pre-repository versions. 3. The assertion also failed with "-dTextAlphaBits=4 -dLastPage=1 comparefiles\xgfddg.pdf".

Fix for 687390 GhostScript 8.11 inserts rendering artifacts with GIFs as source. The actual problem is an error which resulted in a pale yellow being shown as a pale pink. This occurs when dithering on devices which use a 256 color palette. DETAILS The halftoning logic assumes that there are the same number of shades of each color. However the 256 color palette devices were using a 7x7x5 color cube. I.e. there were 7 shades of red and green, however there were only 5 shades of blue. The data in the device's color_info (max_color, max_gray, dither_colors, and dither_grays) indicated that there were 7 shades. The halftoning logic, using this information, was attempting to display the given pale yellow color by dithering between 6/7ths and 7/7ths of each component. However the encode_color routine returned colors which include solid blue for all cases. This biased the resulting halftoned color toward blue. The fix involves changing the 256 color palette devices to use a 6x6x6 color cube. The same routine pc_8bit_map_rgb_color is used for all of the 256 color palette devices. Thus the change consists of modifying this routine and the associated pc_8bit_map_color_rgb routine. The specification of each of the devices has to be changed to represent the change in the cube size.[src/gdevbmp.c 1.9, src/gdevcgm.c 1.10, src/gdevp2up.c 1.5, src/gdevpccm.c 1.6, src/gdevpccm.h 1.7, src/gdevpcx.c 1.6, src/gdevpng.c 1.10, src/gdevsvga.c 1.6]

Fix for incorrect Annotation scaling when an Appearance (/AP) had scaling that was not unity (1) and the Subtype was not /Stamp. Fixes Bug #687288 for customer #32. DETAILS: The scaling difference in the annotation (object 14 0) was due to Ghostscript not recognizing the bsiTextStamp annotation Subtype. Careful reading of the Adobe PDF specification says that if there is an Appearace stream (/AP dict), then the Form XObject should be scaled using the method that we perviously only used for /Stamp Subtype annotations (calcstampscale). The section of the PDF 1.5 Reference Manual is 8.4.4. The patch is fairly simple, but testing of the regression suite showed one file, foo.pdf, that was missing the require /Rect entry in the Annot dict. The patch includes a check and warning for this problem. EXPECTED DIFFERENCES: With this patch, some of the regression files will have slightly different scaling for some of the annotations, but the differences are all too small to compare to Adobe. The largest variations are seen with annots.pdf (our test file) where the scaling ranges from a low of 0.979191 to a high of 1.01636. The files are: filename scaling range (was 1) 01_001.PDF 1.0 SyscoCorrugatedprintcard.pdf 1.0 .. 1.00268 annots.pdf 0.979191 .. 1.01636 rf1025.PDF 0.998471 IMO, these are all close enough to be considered progressions.[lib/pdf_draw.ps 1.80]

Fix for 687364 rangecheck in buildshading2 from Quark XPress PS file. This fix involves the creation of the findcmykcustomcolor and setcustomcolor functions. DETAILS: Ray found that the error message was due to an invalid shading dictionary being given to shfill. The dictionary has a function which has a single input and a single output. The numbers are determined from the sizes of the Domain and Range arrays. Since the shading dictionary is using a DeviceCMYK color space, Ghostscript is generating a rangecheck since the function does not have four outputs. The file is generating an invalid shading dictionary.

Actually the file provides about 16 versions of setcustomcolor. However the versions provided in the file do not work. The PLRM does not mention setcustomcolor. However it is described in Adobe's "Technical Note #5044 Color Separation Conventions for PostScript Language Programs".

Separation applications from Adobe Systems and other vendors will redefine these convention operators to separate your documents. Your application should conditionally define procedures with these special names, as shown later in this document."

DETAILS: This was caused by the zread function reading the character (sgetc) prior to invoking the 'push' macro which could return with e_stackoverflow (discarding the character). The stackoverflow can happen more frequently than at MaxOpStack level since the stack is allocated as blocks, using the e_stackoverflow to signal the need to add more stack blocks, then retrying the operation.

Fix (TT interpreter) : Subglyphs could be placed to wrong coordinates. DETAILS : 1. When a subglyph position is specified with a reference to an outline point, the index of the point was interpreted wrongly and could use an undefined data with an indeterministic result.

Fix to implement PDF specification for '/' as a valid name as opposed to the PS token scanning. Previously //name would be incorrectly scanned as an immediately evaluated name rather than two names '/' and '/name' which is correct. Fixes Bug #687277 for customer #440. DETAILS: Care is taken to reset the scanner behaviour after a PDF file is finished and also after an invalid number is scanned. Note that to reset the flag, the parameter must be set to 'null', not 'false' due to the implementation in the ztoken.c. Caveat impelementor. Previously the PDFScanRules was set when an invalid number was found and was never reset, so this may result is *LOTS* of pdfformaterror messages for files that have lots of invalid format numbers, but that's what they get. If this is ever a problem, reseting the PDFScanInvNum can be moved to pdf_main.ps where PDFScanRules is set to null. No expected differences.[lib/pdf_base.ps 1.42, lib/pdf_main.ps 1.85, src/iscan.c 1.17, src/iscan.h 1.9, src/iscannum.c 1.8, src/ztoken.c 1.13]

A new implementation of shadings, step 43. DETAILS : 1. An optimization : If an area has a monotonic color, each subarea has a monotonic color as well, so the color monotonity doesn't need to recompute. Doing so because the color monotonity function is not fast when appied to a ShadingType 1 with a bicubic color interpolation. 2. Bug: is_color_monotonic returned 'true' when the intrval has zero width by the 1st coordinate. This is wrong for with ShadingType 1, which uses a 2-argument function. ( The check was a rudiment from a 1 month old implementation of fn_Sd_is_monotonic, which returned 'false' when the low boundary is at the end of some cell, and the upper boundary is at the beginning of the next cell. Actually this case is a zero width interval and the function must return true. ) EXPECTED DIFFERENCES : A minor difference in colors : 442-01.ps 464-01.ps Clarke Tate Manns Chinese.ai STEUER-RollingMesh 1(linear).ai[src/gxshade4.h 1.22, src/gxshade6.c 1.48]

Implementing is_monotonic for cubic interpolation functions. DETAILS : The old code ignores extremes of a cubic interpolation function (except ones at a cell boundary). It could cause a wrong rendering of shadings with replacing a randomly big part of the shading near an extremum with a constant color. The new code fixes that. The new code caches the interpolation coefficients. This may cause problems if the function data stream is modified after the function is build. Likely this must not cause problems due to gs/lib caches the stream with ReusableStreamDecode. Also we don't know practical cases. POLE_CACHE_IGNORE 1 avoids this problem with some slowdown, (the slowdown exponentially grows with >=3 arguments, but again we don't know practical examples with >=3 arguments). The configuration flag POLE_CACHE allows to revert to the old code. Bug 687352 "is_monotonic isn't implemented for 3d order sampled function".

Fix for 687337 Zerodivide in cie_cache_mult. Note: There was a typo in the previous fix. DETAILS: The direct cause of the problem, and also the reason that we have not seen this problem in real world files is that the 050-01.ps test file contains the following color rendering dictionary. /RenderDict2 12 dict begin /BlackPoint [ 0 0 0 ] def /ColorRenderingType 1 def /EncodeABC [ {} {} {} ] def /EncodeLMN [ {} {} {} ] def /MatrixABC [ 0 0 0 0 0 0 0 0 0 ] def /MatrixLMN [ 0 0 0 0 0 0 0 0 0 ] def /RangeABC [ 0 1 0 1 0 1 ] def /RangeLMN [ 0 1 0 1 0 1 ] def /RangePQR [ 0 1 0 1 0 1 ] def /TransformPQR [ {} {} {} ] def /WhitePoint [ 1 1 1 ] def Note: The matrices full of zeroes do not represent real world data.

The domain values are later used to calculate a scaling factors which is also 0. Calculations, which use one of these values as a divisor, then generate a divide by zero exception. One option to fix this problem would be to check for zero before doing any calculations with the scaling factors. However another and simpler option is to check for the zero factors when they are crated and set the value to a value which will not cause the divide problem.

MSVC compiler: allowing Precompiled Headers, Incremental Compilation, Edit & Continue. DETAILS : These options are applied to debug build only. They dramatically improve the development technology. Automated Precompiled Header speeds up the compilation slightly. For best results should reorganize gs header files. Incremental Compilation speeds up the rebuilding after editing source code. Edit&Continue is a powerful tool for debugging. Together with incremental compilation it allows to regenerate the object code during a debug session, and continue the debugging with the new code without restarting the program. Press F10 after you changes source code and enjoy. F7 resets the session - forget it. Another related tool is the "Set instruction pointer" debugger command, which is available only from Tools/Customize/Commands/Debug. It looks as an yellow arrow with a blue thin curved arrow. Move it to your toolbar and enjoy. Also enabled the incremental linking. YOU NEED TO REBUILD ALL AT ONCE to activate these tools. Tested with MSVC 6, should also work wirth MSVC 7.

To reproduce the crash apply the patch of the bug 687351 to lib/pdf_font.ps (that patch will be committed AFTER this one). 1. pdf_resize_resource_arrays was called with a wrong array size (gdevpdtc.c). 2. pdf_resize_resource_arrays did not expand CIDToGIDMap (gdevpdtf.c). 3. gs_type42_glyph_info accepted a wrong type of the return value of get_glyph_index. 4. Copying a CIDFontType 2, CIDCount was wrong (gxfcopy.c). 5. pdf_obtain_cidfont_resource wrongly processed the case of shared font descendents : font compatibility was not checked, rather they may have different Metrics, Metrics2, CDevProc, CIDMap (gdevpdtt.c). 6. Implemented a dynamic expansion of CIDMap for copied fonts. 7. In font copies CIDMap used the code 0xFFFF for representing unmapped glyphs. 8. Inserted the comment into gdevpdtf.c : /* fixme : Likely pdfont->u.cidfont.CIDToGIDMap duplicates pdfont->FontDescriptor->base_font->copied->client_data->CIDMap.

Implementing current point with double precision. DETAILS : The old code stores the current point in pgs->ppath->position with the 'fixed' representation in the device space coordinates. This appears insufficiently precise if a document constructs a path with multiple 'rlineto' or 'rcurveto'. A significant to error accumulation happens. We implement the current point with 'double', duplicating pgs->ppath->position with the new field gs_imager_state::current_point. We can't replace pgs->ppath->position with the new one due to several reasons : - Sometimes (in the text processing, in arc processing and in reversepath) a new current point is computed when imager state is not accessible. - Don't want to spend processor time for conversion double to fixed, whenever a fixed is needed. - Don't want to modify many of low level modules; Text operation always round the current point to 'fixed'. Note that the convertion from fixed to double is always precise, therefore we widely use it with text operations. Thus this improves the precision of moveto, lineto, curveto, rmoveto, rlineto, rcurveto, but the precision of other operators left as it was. Likely there is no strong need to improve text operations due to pixel rounding, but it would be useful to improve arc, arcn, arct, arcto. However an improvement of arc operations isn't a high priority, and after this patch becomes a local change. We removed ppath->outside_position, because pgs->current_point now effectively handles this feature. Due to that the rounded pgs->current_point may be unequal to pgs->ppath->position when the current point is outside the range. The configuration flag PRECISE_CURRENTPOINT defined in gxstate.h helps to debug the new code with raster comparizon with the old code. PRECISE_CURRENTPOINT 0 works same as the old code except the coordinate clamping. Therefore once tested with the comparison, the further validation reduced to a validation of the code swtched by the flag - this part pof code is pretty small. The mode (PRECISE_CURRENTPOINT 0) **MUST**NOT** go to production due to the dropped clamping. PRECISE_CURRENTPOINT 1 handles the clamping. Bug 687359 "Current point is inprecise".

Log message: Implement 687347: Implementation of the PDF encryption feature: EncryptMetadata. Past versions of the PDF encryption have always encrypted metadata. With this feature it is possible to NOT encrypt metadata streams. I.e. By adding '/EncryptMetadata false' to the encryption dictionary. DETAILS: There are two pieces to the implementation: 1. The calculation of the user password key includes an additional step of feeding 0xffffffff to the md5 input if EncryptMetadata is false. (Ask Adobe, not me.) The PDF 1.5 spec. says that EncryptMetadata is an undocumented feature of PDF 1.4. This implies that this action needs to be done for values of R in the Encrypt dictionary of 3 or higher. However testing with Acrobat 5.0 and Acrobat 6.0 shows that this is not done for R = 3. Thus we check for R >= 4. 2. Testing with Acrobat 5.0 and 6.0 has verified that the encryption of metadata streams is controlled by EncryptMetadata in both versions. Thus we check for PDF 1.4 and higher (R >= 3) and if so then we check the stream type and the EncryptMetadata flag to determine if a stream needs to be decrypted.[lib/pdf_sec.ps 1.15]

Add a simple C program that uses the jasper library to parse JPX (jpeg2k) image files and embed them in a PDF 1.5 document. Useful for testing as there are few producers available at the moment. DETAILS: We make no attempt to parse the required metadata (resolution and so on) ourselves. It would be simple to add this so that the program can stand alone. On the other hand, jasper is capable of opening a number of other image formats and encoding them to jpx streams. We don't do that either, but it would also be easy to add support for so that JPXDecode versions of arbitrary images could be embedded.

Fix : Raster depended on bands, step 3. DETAILS : Bug 687222 "Raster depends on bands". Switching to the new code. Now trapezoid sides are independent on bands, clipping and scans. Any trapesoid side is equal to some flattened piece of an outline segment. A massive difference happens due to the old code recognized low trapezoids as rectangles. The new code does not because it checks the verticality with longer bars. EXPECTED DIFFERENCES : Almost all comparefiles render differently., but mist differences are single pixels.

Implementation of 687326 Enhancement: Handling of PDF 1.5encryption. DETAILS: The PDF 1.5 specification has added several some features for encryption of PDF documents. 1. The new encryption changes are indicated by a /R value of 4 in the Encryption dictionary. Note: The encryption algorithm is the same as /R = 3. 2. The encryption handling for strings and streams may now be specified independently. Current possibilities are 'Identity' and the standard handler. Note: There are more encryption features in the PDF 1.5 specification. HowevertThe only means that I have for generating test files for these new encryption features is Acrobat 6.0. This patch will decode files which are encrypted using Acrobat 6.0. There is one more feature (EncryptMetaData) which will be the subject of a separate patch. Between the features covered by the current patch and the EncryptMetaData patch, this includes all of the capabilities that are available to a user of Acrobat 6.0. Since Acrobat 6.0 is the major producer of files with these new encryption features, Ghostscript will have the ability to decrypt files which we are likely to see in the near future.[lib/pdf_sec.ps 1.14]

Fix for 687274 White areas appear shaded. DETAILS: This 'problem' is caused by a 'feature'. The high resolution transfer function deliberately has a piece of logic that forces any shade of gray that is not pure white (i.e. greater than 0.998) to halftone with at least one pixel being set in the output. This keeps nearly white shades from being washed out. We have seen several instances in which this 'feature' causes a problem. The fax output format tiffg4 has been bitten by this problem since it is commonly used at 204 dpi. This change removes this feature.[lib/gs_init.ps 1.105]

Fix (pdfwrite) : Errors were missed processing a shading data stream. DETAILS : Bug 687307 "A ShadingType 7 differs from Adobe." shade_next_flag interpreted a wrong data as End-Of-Data, so that some wrong documents were passed with no error. Now pdfwrite handles the bad shading data exception separately from other errors: the shading is fully written and the error is signaled to the PS interpreter after that. Note that other errors terminate immediately with inconsistent data written to the PDF output. We did the special processing to provide a better conformity to some buggy Genoa tests, which paint a shading with a wrong data in a stopped context. Besides that, we cancelled the default implementation fallback when pdf_setfillcolor fails. The old implementation caused shadings to convert into a huge set of rectangles written to PDF. We believe that signalling an error is the right reaction for this case. EXPECTED DIFFERENCES : pdfwrite : 446-01.ps now prints error message to the raster. This is a progression. 483-05.ps now prints error message to stdout. This is a progression.[src/gdevpdfd.c 1.37, src/gdevpdfg.c 1.47, src/gdevpdfv.c 1.34]

A new implementation of shadings, step 32. DETAILS : 1. Implemented axial shading with a Coons patch. It gives more regularity with area decomposition and trapping. 2. Optimized tensor shadings for the case when the gradient is parallel to the quadrangle sides. Note that the old code applies 1/2 pixels fill adjustment when painting stripes of the shading, generating overlapped stripes. Instead that the new code generates non-overlapping stripes, and applies a trapping emulation at the shading boundaries with 1/8 pixels. EXPECTED DIFFERENCES : A minor difference with axial shadings : 442-01.ps 446-01.ps 464-01.ps 483-01.ps 483-05.ps BEST8-99-Path.fh7.pdf chilis_black.pdf chilis_red.pdf gradmesh.ai Openhuis_pdf_zw.pdf SmoothShading.pdf STEUER-RollingMesh 1(linear).ai STEUER-RollingMesh 3(Final).ai Testform.v1.0.2.pdf An area shift in Testform.v1.0.2.pdf at 72dpi appears due to the fill adjustment is replaced with the trapping emulation.[src/gxshade1.c 1.20, src/gxshade4.h 1.17, src/gxshade6.c 1.35, src/lib.mak 1.172]

Check for local jpeg library source by looking for the jpeglib.h header rather than just the jpeg directory. Also try looking for jpeg-6b if the jpeg fails; this lets us find the source as it unpacks from the upstream tarball. Patch from ESP Ghostscript.[src/configure.ac 1.42]
Add a parameter which prevents the non-standard four element PageSize entry in the InputAttributes from being included. This prevents problems with PostScript programs that examine the InputAttributes entries in an attempt to pick the 'best fit' rather than relying on the setpagedevice logic. Also most 'real' printer devices don't support arbitrary page sizes, so automatic rotation is defeated if the range type page size in included. The option is -dNORANGEPAGESIZE. Bug #629335.[doc/Use.htm 1.101, lib/gs_setpd.ps 1.21]

Initial implementation of the JPXDecode filter using the JasPer library for decoding the JPEG 2000 data. This version only implements a postscript-level filter; PDF support will follow in another commit. DETAILS: A new FEATURE_DEV, 'jpx.dev', is added to the makefile to enable support. The jasper library must be available to link with in this case. The library is autodetected in the autoconf build, but not yet enabled on other platforms. The implementation leaves a little to be desired. While JasPer is robust, it provides no way to connect its internal stream architecture to ours, so we end up buffering all the data. This seems to be the best we can do without modifying the library. We try to handle data from a number of colorspaces, but the spec is a little vague on what is required. We convert YUV to RGB internally, but do not handle sub-sampled planes.[src/Makefile.in 1.33, src/configure.ac 1.41, src/int.mak 1.124, src/lib.mak 1.171, src/sjpx.c 1.1, src/sjpx.h 1.1, src/zfjpx.c 1.1]

Improving the filling algorithm, step D7. DETAILS : When filling an individual trapezoid, a shortcut for parallelograms could miss some pixels. When the left boundary rounds to a vertical line and the right one does not, for the right boundary it wrongly applied same zero sampling as for the left one, in spite of the right boundary can cross pixel centers. We realize that the shortcut could improve a view of some parallelograms. But in same time we detected that in alphabet.ps with 72dpi a parallelogram was replaced with a wider one, causing a worse view of the character '#'. So its usefullness is arguable. Both features can't provide simultaneousely due to the device interface can't pass a flag whether an exact coverage is required. Therefore we drop the shortcut.

A new implementation of shadings, step 7. DETAILS : Documenting the current state of the development, because we need to delay the project. EXPECTED DIFFERENCES : None.[src/gxshade6.c 1.13]
Adapt makefile support for compiling in zlib to support v1.2.x rather than 1.1.x. Linking to a shared version is unaffected. DETAILS: The zlib source was re-arranged from the 1.1.4 to the 1.2.x releases. While binary compatibility was maintained, and we link just fine to a separately build dynamic zlib, our custom makefile support for compiling in the library source no longer works. Rather than add a 'ZLIB_VERSION' makefile variable and the attendent configuration costs, we've simply migrated completely to the new (much faster) 1.2.x series. 1.2.1 is now the minimum version to be used if you wish to compile zlib as part of Ghostscript.[doc/Make.htm 1.71, src/zlib.mak 1.8]

Improving the filling algorithm, step D6. DETAILS : The algorithm for for filling an individual trapezoid used a wrong formula when rounding a coordinate to pixel index. An intersection of a trapezoid boundary with a scanline is represented as a rational value, in which the fraction represent a part of an unit of 'fixed'. Computing a pixel index, the fraction was ignored. Due to that the spot sides were biased into about 1/256 pixels. The bias appears important when some trapezoids are fixed with swapped coordinate axes, because the bias appears in an opposite direction to one with unswapped axes. Therefore a decomposition of a shading missed pixels, which fall exactly into the biased boundary, causing a dropout. Here is the analyzis of the old rounding : We must paint pixels with index i such that Xl <= i + 0.5 < Xr The condition is is equivalent to Xl - 0.5 <= i < Xr - 0.5 which is equivalent to (is_integer(Xl - 0.5) ? Xl - 0.5 : ceil(Xl - 0.5)) <= i < (is_integer(Xr - 0.5) ? Xr - 0.5 : floor(Xr - 0.5) + 1) (the last '+1" happens due to the strong comparizon '<') which is equivalent to ceil(Xl - 0.5) <= i < ceil(Xr - 0.5) trap_line represents the intersectiion coordinate as a rational value : Xl = xl + e - fl Xr = xr + e - fr gxdtfill.c computes l.x = x0l + (fixed_half - fixed_epsilon). In our notation it is equal to : xl' := xl + 0.5 - e xr' := xr + 0.5 - e Then xl = xl' - 0.5 + e xr = xr' - 0.5 + e Xl = xl' - 0.5 + 2e - fl Xr = xr' - 0.5 + 2e - fr ceil(xl' - 0.5 + 2e - fl - 0.5) <= i < ceil(xr' - 0.5 + 2e - fr - 0.5) which is equivalent to ceil(xl' + 2e - fl) - 1 <= i < ceil(xr' + 2e - fr) - 1 We have : ceil(xl' + 2e - fl) - 1 == (is_integer(xl' + 2e - fl) ? xl' + 2e - fl - 1 : ceil(xl' + 2e - fl) - 1) == (is_integer(xl' + 2e - fl) ? xl' + 2e - fl - 1 : floor(xl' + 2e - fl)) Since -e <= fl < 0, it is equal to (is_integer(xl' + e) && e == fl ? xl' + 2e - fl - 1 : floor(xl' + 2e - fl)) == (is_integer(xl' + e) && e == fl ? xl' + e - 1 : is_integer(xl' + e) && e != fl ? floor(xl' + 2e - fl) !is_integer(xl' + e) && e != fl ? floor(xl' + 2e - fl) !is_integer(xl' + e) && e == fl ? floor(xl' + 2e - fl)) == (is_integer(xl' + e) && e == fl ? xl' + e - 1 : is_integer(xl' + e) && e != fl ? xl' + e : !is_integer(xl' + e) && e != fl ? floor(xl' + e) !is_integer(xl' + e) && e == fl ? floor(xl' + e)) == (is_integer(xl' + e) && e == fl ? xl' + e - 1 : floor(xl')) And the condition is equivalent to (is_integer(xl' + e) && e == fl ? xl' + e - 1 : floor(xl')) <= i < (is_integer(xr' + e) && e == fr ? xl' + e - 1 : floor(xr')) But the old code computes floor(xl') <= i < floor(xr')) Thus when is_integer(xl' + e) && e == fl, it wrongly shifts the rounded boundary in 1 pixel to the left. EXPECTED DIFFERENCES : Almost all tests render differently.

Improving the filling algorithm, step D5. DETAILS : It's a preparation for fixing a problem while filling a single trapezoid. This change improved a debug drawing. EXPECTED DIFFERENCES : None.[src/gxdtfill.h 1.14]
2004-02-16 09:13 Igor Melichev
A new implementation of shadings, step 6. DETAILS : The new code is disabled with NEW_TENSOR_SHADING 0. 1. Implemented a debug drawer draw_wedge. 2. dbg_nofill was not properly initialized. 3. Removed a debuging hack. 4. removed unused variables. EXPECTED DIFFERENCES : None.[src/gxshade6.c 1.12]
2004-02-16 09:10 Igor Melichev
Improving the filling algorithm, step D4. DETAILS : It's a preparation for fixing a problem while filling a single trapezoid. This change is algorithmicaly equivalent. EXPECTED DIFFERENCES : None.[src/gxdtfill.h 1.13]
2004-02-16 08:21 Igor Melichev
Improving the filling algorithm, step D2. DETAILS : It's a preparation for fixing a problem while filling a single trapezoid. This change is algorithmicaly equivalent. It branches out the rectangle case and simplifies it. Some macros are moved by necessity. EXPECTED DIFFERENCES : None.[src/gxdtfill.h 1.12]
Fix for 687294 psdcmyk device does not write resolution correctly to PSD files. This change adds a 'ResolutionInfo structure' into the 'Image Resources' section of the output file. This structure specifies the horizontal and vertical resolution of the image. (Note: Adobe's support of asymetric resolutions is poor.)[src/gdevpsd.c 1.6]
2004-02-15 14:51 Igor Melichev
Fix: Improving the documentation (comments) about the filling algorithm, improved. DETAILS : The prevoius change to the comment appears wrong, i.e. the old expression "x + xf/h + 1" appears correct due to compute_ldx subtracts h from the remainder but doesn't add 1 to the integer part, which is x. EXPECTED DIFFERENCES : None.[src/gdevddrw.c 1.13]
2004-02-15 11:31 Igor Melichev

Improving the filling algorithm, step D1. DETAILS : 1. The 'peak' condition was too weak. Caused minor differences in rasters with dropout prevention. 2. Expanded loop_fill_trap_np in the inner trapezoid loop. This change is algorithmically equivalent. 3. Cleaned the inner loop with moving out the computations if ybot, ytop. This change is algorithmically equivalent. 4. Moved the (ybot < ytop) check outside the trapezoid loop. This change is algorithmically equivalent. 5. Inserted 'const' into loop_fill_trap_np. 6. Inserted the section "Reserved to improve the banding" to simplify experiments with it.

Fix (pdfwrite) : Charproc can change scale before calling setcachedevice. DETAILS : Bug 687290 "pdfwrite generate too large glyphs". To know that CTM changed by a charproc before setcachedevice or setcharwidth, we set identity CTM before entering the charproc. If setcachedevice or setcharwidth decides to fall back to the default implementation, we restore the CTM in there. The condition in gdevpdtt.c 1931 is changed, causing minor differences with Bug687044.ps and muur.eps . We found that a further improvement would be useful for a better handling of a composite font with a Type 3 descendent. Opened the new bug 687298 about this issue. Differences with Bug687044.ps and muur.eps may be related to it. EXPECTED DIFFERENCES : A minor shift of glyphs with pdfwrite : Bug687044.ps muur.eps[src/gdevpdf.c 1.88, src/gdevpdfx.h 1.85, src/gdevpdtt.c 1.73]

Fix: Improving the decision whether the dropout prevention to be applied. DETAILS : 1. The old code applied the dropout prevention if gx_fill_params::adjust = 0. It worked since the latter was set to 0 only for characters. Now we intend to discontinue the fill adjustment with shadings, so the old condition won't be applicable in further revisions. Therefore we reserve the value -1 of gx_fill_params::adjust especially for designating characters with a dropout prevention, and percept it in the filling algorithm (We tried to use new special flag for designeting characters, but it requires an enhancement to the clist language.). 2. The old code has a problem with PaintType 2 fonts : it applied the dropout prevention to strokes. This patch fixes that with checking PaintType in gxtype1.c .

Simplifying the filling algorithm, step C17. DETAILS : Do not filter out short flattened segments. We believe that the old code was not conforming to PLRM due to filtering small segments after flatteingng a curve. We believe that the filtering has 2 purposes : 1. Prevent the filling algorythms from zero length segments; 2. Speed up the filling with reducing the number of vertices in a polygon. The new filling algorithm handles zero length segments with no problem, and the speeding up appears within 1% except for shadings. We believe that the rendering quality is more important. The performance of shadings to be fixed separately.

Simplifying the filling algorithm, step C16. DETAILS : Switching to the new scanline algorithm based on the flattened iterator. Now both the trapezoid and the scanline algorithm use same flattened path. Differences in rasters appears due to 2 reasons : 1. An inprecise expressions used in the old algorithm in gx_curve_x_at_y : the iteration of midpoint_fast accumulates a big rounding error. The new algorithm have smaller error due to 3*log2(N) fraction bits while the coordinate accumulation, where N is the number of flattened segments. 2. The old algorithm used inprecise expressions in pco_monotonize. The new algorithm applies a flattening instead the monotonization.

Simplifying the filling algorithm, step C7. DETAILS : This is a preparation for removing the coord_near filter from the flattening algorithm. We believe that the the coord_near filter was implemented for two purposes : (1) prevent the filling algorithm from zero-height segments, and (2) speed up the filling with reducing the number of vertices in the polygon. Now the filling algorithms can handle zero length segments due to conformity to gx_flattened_iterator. Thus the reason (1) is not longer important. The skipping of some vertices speeds up in 3% at 600dpi rendering with ppmraw to null file. But sometimes it produces raster distortions, such as an asymmetric raster for symmetric outlines. When we fixed the distortions, the speeding up appears within 0.5%. We decided to remove the coord_near filter, because so small echonony of processor time is less important than the distortions. This patch introduces a new swicth DONT_FILTER_SMALL_SEGMENTS, and make the compilation of coord_near filter to depend on it.

pdfwrite : Implementing the PDF 1.4 encryption, step 14. DETAILS : Elements of pdfmark elements were not encryptrd. Since gs/lib/gs_pdfwr.ps serializes pdfmark elements, we would like to encrypt them before the serialization. However it would require to implement a new PS operator to pass the encription keys from the device to the PDF interpreter. Since this way appears cumbersome, we decided to unserialize data in the device. For doing that we implement a simple parser in pdf_put_composite. EXPECTED DIFFERENCES : None.[src/gdevpdfu.c 1.50]

Fix : Partially restoring the old behavior of the filling algorithm. DETAILS : When we dropped the compatibility with the patch http://www.ghostscript.com/pipermail/gs-cvs/2004-January/004061.html, one case of the flattening condition was not perfect. Sorry for detecting this late. Now we put another condition, which differs from both the old and the last one, but the new one is symmetric and provides lesser distortions.

Simplifying the filling algorithm, step B1. DETAILS : This starts a new sequence of patches to the filling algorithm. It's goal is a further simplification. We deetected that MERGE_COLLINEAR_SEGMENTS 1 section is an old optimization, which speeds up in 1.3% and complicates the code in 30%. Besides that, it causes inprecise results with the dropout prevention. At last, the name "MERGE_COLLINEAR_SEGMENTS" doesn't reflect its effect : actually it merges segments nearly parallwel to coordinate axis, which may be unlimitedly long and have an unlimited angle. Therefore we believe that this optimization is not well defined, appears unuseful, and to be cancelled. This patch is a preparation for removing the MERGE_COLLINEAR_SEGMENTS section. We made this switch global and we bracketed more code sections, which appear unuseful without MERGE_COLLINEAR_SEGMENTS. This patch almost is a change to a disabled code. But the change to gxfill.c ln 1238,1241 goes to the enabled code and appears algorithmically equivalent : with MERGE_COLLINEAR_SEGMENTS 1 this branch is equivalent to noop. EXPECTED DIFFERENCES : None.[src/gx.h 1.32, src/gxfill.c 1.87, src/gxpflat.c 1.29]

Fix : pco_accurate didn't work for curves with zero derivative. DETAILS : Bug 687266 "Accurate curves may be inaccurate.". EXPECTED DIFFERENCES : None, because normally PS doesn't use "true .setaccuratecurves". Testing with "true .setaccuratecurves", got no difference with -r72. Thus our testbase doesn't contain interesting curves.[src/gxpcopy.c 1.18]
Create a new dynamic header 'gconfigd.h' for non-platform-specific defines. Variables like GS_LIB_DEFAULT which were previously tacked onto the end of gconfig.h have been moved to the new header. This change is necessary to pass the default path for the persistent cache from the makefile. DETAILS: The persistent cache is implemented in the gp layer, but previously it was illegal to access gconfig.h from code inside the graphics library, it the sense that the build would fail. This is because of the crazy way operator definitions are collected in dev files before they are consolidated in gconfig.h. We don't want to use gconfigv.h because that header is platform-specific is generated by different code on every platform. Therefore, while this isn't a real fix for gconfig.h circular inclusion issue, a new header is reasonably motivated.[src/gp_unix_cache.c 1.2, src/gs.mak 1.25, src/gscdef.c 1.42, src/iconf.c 1.7, src/int.mak 1.122, src/lib.mak 1.162, src/unix-aux.mak 1.12]

Fix : Don't apply pco_accurate when filling a path. DETAILS : When a path is is being stroked, it first converts to the stroke outline, and pco_accurate is being applied. When the stroke outline is being filled, pco_accurate was applied at second time with no useful reason. When it fills a character, pco_accurate disturbs the hinted outline. Thus it must not apply with 'fill' in any case. EXPECTED DIFFERENCES : None, because normally PS doesn't use "true .setaccuratecurves". Testing with "true .setaccuratecurves", almost all tests render differently due to characters, and we believe it's a progression.[src/gxfill.c 1.86]

Replace a fixed-filename tempfile fopen with gp_open_scratch_file() for improved robustness in the pnga device. Part of the fix for bug 687243. DETAILS: This is an experimental device to preserve pdf transparency into a png rasterization and is distinct from the pngalpha device. I doesn't actually work for me and so may be suffering from bit rot; however the change compiles and should be correct.[src/gdevpnga.c 1.8]

Fix : The PCL interpreter doesn't provide pattern streams (continued). DETAILS : 1. Restored the PATTERN_STREAM_ACCUMULATION 0 code from gdevpdfv.c revision 1.27. It provides a conversion of a pattern tile into a PDF pattern object. 2. Passed have_pattern_streams to corresponding parts of pdfwrite. 3. Added a check for have_pattern_streams into zpcolor.c . It is useful for debugging PS interpreter with passing have_pattern_streams=false to gs_state_set_client. With PS interpreter the new code never executes (unless one changes the call to gs_state_set_client). EXPECTED DIFFERENCES : None.[src/gdevpdfg.c 1.46, src/gdevpdfg.h 1.29, src/gdevpdfv.c 1.33, src/int.mak 1.121, src/zpcolor.c 1.12]

Fix (PDF interpreter) : CropBox computed wrongly. DETAILS : Bug 687244 "wrong interpretation of negative mediabox coordinates". The bug title appears incorrect. Actually the problem is caused by negative CropBox coordinates. .pdfshowpage_Install translates the coordinate system to provide positive coordinates, but pdfshowpage_finish did not account the translation when writing the CropBox. Therefore it the resulting CropBox was inconsistent with the painting when the source CropBox uses negative coordinates. EXPECTED DIFFERENCES : A progression with vtm2k.pdf .[lib/pdf_main.ps 1.84]

pdfwrite : Merge redundant images (continued). DETAILS : Bug 687224 "large pdf file size". The patch http://www.ghostscript.com/pipermail/gs-cvs/2004-January/003988.html appears incomplete, because it works only with << /EncodeColorImages false >> setdistillerparams The problem happens due to Decode arrays considered always unequal. This patch : 1. Implemets cos_array_equal. 2. Applies it properly to subobjects (particularly to Decode). 3. Fixes the function cos_dict_equal - it was asymmetric. 4. Improves the error processing while object comparizon. EXPECTED DIFFERENCES : None in rasters, some PDFs become shorter.[src/gdevpdfo.c 1.26]

Fix : The PCL interpreter doesn't provide pattern streams. DETAILS : gx_pattern_cache_lookup falied when called by the PCL interpreter because the PCL interpreter doesn't provide high level pattern streams. Actially the compatibility of the graphics library to the PCL interpreter was broken since gsptype1.c revision 1.16. This patch introdices a new argument for the function gs_state_set_client. Using the argument, a client tells to the graphics library whether the client provides pattern streams. If not, the graphics librery emulates the old behavior based on raster parretns only. The new flag gs_imager_state::have_pattern_streams stores the compatibility mode. We would prefer it to be a member of the graphics library instance, but the instance is not implemented yet. Storing it to gs_imager_state may cause some undeserable effects, especially when a device creates a temporary graphic state for an internal use (the clist device is an example). We assume that none of devices provides pattern streams, and this assumption should be reasonable for current applications. The mechanizm for generating patters streams is still coded specifically to the PS interpreter in pattern_paint_prepare in zpcolor.c . This solution to be considered as a temporary one. We should refactor it into 2 parts : one specific for the PS interpreter, and another one being common for all applications, which should be a part of the graphics library. This patch had passed the regression test with the PS interpreter, but it was not tested with the PCL interpreter. Debugging it with PCL to be a next step. EXPECTED DIFFERENCES : None.[src/gsistate.c 1.9, src/gsptype1.c 1.18, src/gsstate.c 1.23, src/gxistate.h 1.19, src/gxstate.h 1.9, src/zgstate.c 1.9]
Fix for "687252 subfiledecode errors on includes greater than the size of a uint". In spite of the bug name, the problem is not related to the actual size of the subfile or to the size of a uint. The actual problem is a missing required parameter: EODCount. However Adobe once again ignores the missing parameter and what is specified in the PRLM-3rd. DETAILS: The given test file has a SubFileDecode filter without the required EODCount parameter. Ghostscript is rejecting the test file because the parameter is not defined. The RangeCheck error message is the result of the following piece of code in zfilter.c: if ((code = dict_int_param(op, "EODCount", 0, max_int, -1, &count)) < 0) return code; This sets a default value of -1 for EODCount and then checks it against the range 0 to max_int. Thus when EODCount is not found we get the rangecheck since -1 is outside the allowed range. In spite of the fact that the EODCount is a required parameter, Adobe Distiller 6.0, my CP1700PS printer, and CPSI 3010.105 print this file without complaint. This fix changes the default value to 0 to match Adobe and adds a comment explaining why the code differs from the spec.[src/zfilter.c 1.10]

Fix (type 1 hinter) : Wrong outline with a huge scale. DETAILS : An arithmetic error happened when scaling a glyph to a huge size (about 100000 pixels), causing a wrong outline. Actually some coordinate values were replaced with zeros. Thanks to Jeong Kim for detecting that. The bug was detected with -r1500 with the test file of the bug 686975 "Black box when converting to tiff". Note that the bug report is wrong : it says that the document with -r150 is bad and -r1500 is good. Comparing rasters with Adobe we concluded exactly vise versa : -r150 was compatible and -r1500 was incompatible. After this patch both resolutions are compatible to Adobe. Probably the user won't like them due to a bug in the document : it paints a huge glyph, which is a hundred times bigger than the page size. The document needs a fix. EXPECTED DIFFERENCES : None with comparefiles.[src/gxhintn.c 1.42]

Fix for 687247 x11 device fails with CMYK on 8bit display. DETAILS: Inside gxcmap.c, the handling of color mapping for most devices is either halftoned or direct. However the x11 device when in 8 bit mode, and possibly other 256 color devices, use a slightly different path. First the color is processed in direct mode. If a color is not in the palatte and halftoning is required, then gx_no_color_index is returned as a color value. Then the color is processed as being halftoned. However this last path was dropped from CMYK colors with revision 8.0.[src/gxcmap.c 1.18]

Initial commit of the persistent cache implementation. This version supports only the *nix platform and does not include any eviction logic. Also currently the cache directory and empty 'gs_cache' index file must be created manually. DETAILS: Two new calls have been added to the gp layer: gp_cache_insert() and gp_cache_query(). These take a byte buffer as a key under which another buffer can be stored or recalled. In addition to the key, buffers are filed by 'type' which provides a separate namespace for each kind of data. These types should be one of the GP_CACHE_TYPE_* defines in gp.h. The query call takes a callback for allocating the buffer to be filled. Thus, all memory management for the key and value buffers is handled by the client and the query returns the data (if any) within a single call. A pair of postscript test operators, .pcacheinsert and .pcachequery are provided in zmisc.c, however they are disabled by default to prevent access to the cache by malicious postscript programs. They operate only with the 'test' type, so a denial-of-service attack is the only real risk; however we anticipate all access will be from C code. Compile with the DEBUG_CACHE preprocessor symbol to enable these. Improvements and implementations for other platforms are to follow.[src/Makefile.in 1.31, src/gp.h 1.27, src/gp_dvx.c 1.11, src/gp_iwatc.c 1.17, src/gp_mac.c 1.15, src/gp_mswin.c 1.23, src/gp_os2.c 1.30, src/gp_os9.c 1.12, src/gp_unix.c 1.13, src/gp_unix_cache.c 1.1, src/gp_vms.c 1.37, src/gs.mak 1.24, src/unix-aux.mak 1.11, src/zmisc.c 1.6]

Fix to prevent setdistillerparams from erasing the page device or reset the page device parameters. Fixes bugs 563287 and 607425.

Fixing a punctuation inaccuracy in documentation.[doc/Language.htm 1.82, doc/Use.htm 1.98]
Fix problems with the "image" device when the palette is an 8-bit gray palette (uses the image8 device with num_components == 1). Since the DeviceN changes, changing num_components requires also setting the gray_index value appropriately. Also the rgb to color mapping function did not allow for num_components == 1 and used uninitialized values for the green and blue comonents. Fixes bugs 458261, 686909 and 687204. DETAILS: The gray_index value was being left at GX_CINFO_COMP_NO_INDEX, so the gx_device_has_color macro indicated a color device. This means that when the gs_initialize_wordimagedevice function changed the num_components value to 1, the gray_index was incorrect (should be 0 for a gray shade device). Also the mem_mapped_map_rgb_color function didn't check for num_components == 1, thus using uninitialized cv[1] and cv[2] values and getting incorrect palette selections. Also I optimized the single component case a bit as well as an "early out" for both color and monochrome when diff == 0 (can't get any better than a perfect match). I guess 8-bit monochrome image devices haven't been used much. Expected Differences: none. (we don't test ps2epsi in the regression suite).[src/gdevmem.c 1.7, src/gsdevmem.c 1.5]

pdfwrite : Merge redundant images. DETAILS : Bug 687224 "large pdf file size". With this change pdfwrite compares images for equality and merges same images into a single XObject, except for inline images. A new pdfwrite device parameter MaxInlineImageSize controls inline images. See gs\doc\Ps2pdf.htm . Use it to disable inline images if the source document contains multiple redundant small images. A new vitrtual function cos_object_t::cos_procs->equal is implemented for object comparizon. But the current implementation is restricted with current needs. Particularly it doesn't implement cos arrays, and assumes equal stream segmentation for equal streams. To be improved someday. Note that an image is copied to temporary file before a comparizon. If the image appears redundant, the current implementation sometimes doesn't release the space consumed in the temporary file. Therefore the disk must have enough space for storing all copies. We could improve this using a smarter method than cos_stream_release_pieces, because an image can interlive only with same image of an alternative compression. To be improved someday.

Unequivocally include stdlib.h in echogs.c to avoid a warning on the Sun ONE Studio 7 compiler as reported in bug 687234. DETAILS: The code in echogs.c calls exit() which is defined in stdlib.h. However it was not including that header (except) on VMS because of portability concerns, resulting in the reported 'implicit function definition' warning. The echogs program must be available before genarch runs and the std.h-based portability headers are available, so wide build support for this code is important. However, such platforms are now very old and comments elsewhere in the code suggest that any compiler supporting ANSI prototypes as we now require will also have a stdlib.h that defines exit(). If this change causes a problem, #ifdef code similar to what was used in gp_unix.c can be used instead.[src/echogs.c 1.7]

Change to gxhintn.c is algorithmically equivalent. 3.

In gxttfb.c applied a curve monotonization after decoding a True Type glyph. It allows to apply Type 1 hints to non-monotonic stems. This change currently is disabled. 6.

Fix for fonts being displayed using .notdef character (empty boxes or other appearance). While the test file doesn't follow the PDF 1.3 or later manual recommendations for providing a [1,0] cmap for an embedded symbolic TT font, Adobe Acrobat Reader can display these characters. When the 'post' table doesn't provide the glyphs required by the /Differences list, try another cmap [3,0] to get the correct glyph (names and glyph #'s). Bug #686959 for customer #1060. DETAILS: The Adobe PDF 1.4 Reference Manual has some "hints" for producing portable PDF's, but as far as reading PDF's that don't follow these hints, all that is said (in section 5.5.5, p.333) is: Note: Some popular TrueType font programs contain incorrect encoding information. Implementations of TrueType font interpreters have evolved heuristics for dealing with such problems; those heuristics are not described here. For maximum portability, only well-formed TrueType font programs should be used in PDF files. The approach of trusting the 'post' table unless the glyphs given do not include glyphs that are mentioned in the 'prebuilt_encoding' (Differences), is a heuristic that works for this file and doesn't interfere with any other PDF's in the regression test. The thing about heuristics is that the 'intelligence' they embody is no better than the understanding of the best solution, so this may crop up again later (but we hope not). Note that simply using the 00030000 cmap [3,0] format causes the regression file 'test_multipage_prob.pdf' to fail with some .notdef characters.[lib/gs_ttf.ps 1.35]

Fix : monotonize_internal didn't work properly. DETAILS : We believe that the new code ever gives monotonic segments, rather than the old one does not - see Bug 687210 "a bug in monotonize_internal". The new code sometimes gives slightly different segments, because the old code applies an incorrect rounding. This causes minor differences in rasters.

Fix : Trapezoid algorithm could cause topology distortions. DETAILS : There were 2 types of possible distortions : inversed or self-intersecting trapezoids, and overlapping trapezoids. Rather they are pretty rare (and a consequtive pixel miscoverage are extremily rare), they break the topology analyzis with the spotan device. The distortion happen due to inprecize computations of line intersections. The coordinate of the intersection is represented in 'fixed', which can't be precise in most cases. Therefore the intersection point appear slightly shifted. The harmful thing was a different shift of the same point for each of the intersecting lines. This patch brings 2 improvements : 1. Intersecting 2 lines, assign same X to both. A special care is taken about vertical lines. 2. After intersections are computed, we check whether the coordinates appear in a wrong order by X. If so, we fix it with computing the average coordinate and assigning it to all lines. This must give a correct topology with a small processor time expense.

Raster depended on the band size (a partial fix). DETAILS : The old code used the Y coordinate of a top boundary of a band as a basis for computing a sampling factor of sloped lines. Therefore sloped lines generated "stairs" with a dependence of the phase on the band coordinate. This patch removes that dependence. Therefore the new banded raster appears closer to the unbanded raster. But the banded raster still can be different. We don't intend to fix it now. We did only a simplest part, which is neccessary for the current development needs. This patch also causes some differences, which are not related to the banding. This happens due to bands and clip boxes come to the filling algorithm in same data field. The dependence on the clip box is dropped as well. Particularly it affects shadings, especially radial ones.

Fix : The dropout prevention code could render an occasional raster. DETAILS : We discovered that the old filling algorithm has a non-well-defined behavior when painting a group of contacting vertical stems with dropout prevention. The result of the old code appears depending on the order of lines in the X list. However when vertical lines have same X coordinate, their order was occasional, and the resulting raster appears deterministically occasional. A new section in gxfill.c near line 1629 fixes that, see comment in there. Another included change to a disabled code brings the curved trapezoid algorithm closer to the uncurved one. It fixes 2 minor problems with horizontal lines. EXPECTED DIFFERENCES : This patch causes a minor difference in some rasters, which we consider as progressions due to lesser dropouts. (Well, it is arguable whether the old feature is a dropout at all, but we'd like to have a well defined raster with no dependence on unimportant things such as which contour point is choosen for the starting point).

An useful improvement would be to divide big curves on-fly (it should be pretty simple with subclassing the gx_flattened_iterator and regenerating the next curve part from entire curve by the part index), and to replace curve_cursor with gx_flattened_iterator in the scanline algorithm.

Fix setpagedevice problems introduced with previous commit detected by the regression tests, including 070-01.ps and many others. Also give priority to lower value slots (match_key.value.intval) DETAILS: If there was a match that didn't set a new value in 'best_mismatch' (less than the original 'LARGE' value), the match_key would be left at 'null', causing PolicyReport to be executed. The Genoa tests use PolicyReport to leave a value on the stack that eventually signals 'FAIL' since the count is greater than expected. This latest change makes sure that a valid key gets set even when the best_mismatch value is not relevant. The lower number slot (%MediaSource) is given priority in the case of a tie between best_mismatch and mbest.[src/zmedia2.c 1.12]

Generalize the trapezoid filling algorithm for curves, step 14. DETAILS : This patch changes a disabled code only. Before this patch the backward iterator works fine, but we are unhappy of its complexity. Rather it passed the full testing with comparefiles, a theoretical proof of its correctness is too hard. Also it highly depends on the old code in MERGE_COLLINEAR_SEGMENTS section, which doesnt look as a well defined code. Therefore we went back to the implementation based on a bitmask. It represents which points were filtered out while the forward iteration. It consumes some bigger memory (488 bytes per active line), but we believe that the C stack consupmtion is still lesser than one in the Type 1 hinter. Now we bring both implementations into a single revision, and define a configuration macro FLATTENED_ITERATOR_BACKSCAN for switching between them. The KISS principle strongly votes for the bitmask implementation. This patch also renamed CHECK_BACKSCAN_CONSISTENCY with FLATTENED_ITERATOR_SELFTEST for a better structurization, and removed some low useful comments.

Fix InputAttributes initialization to have the default page size in slot 0, and all page sizes known in statusdict/.pagetypenames included with the 'fit any' pagesize range last. Fixes bug #617077 and other files that expect slot 0 to be a valid 2 element PageSize corresponding to the default. DETAILS: As noted, "real" printer devices such as laserjets, and inkjets should set up their own InputAttributes dictionaries that do not include the 'range' type page size. If the page size is not an exact match (off by less than 5 points), then the page size range will take priority. This is in a non-standard area of Ghostscript, but must be preserved for those that want exact PageSize such as for generating raster images of a specific dimension. If the range page size is present, then automatic rotation will not be used. If a PageSize is present in both orientations, such as [612 792] and [792 612], then priorty will be given to the slot that matches without automatic rotation.

Generalize the trapezoid filling algorithm for curves, step 11. DETAILS : This patch contains a minor change to the enabled code, and a big change to the disabled code. The change to the enabled code only inserts some new fields into gx_flattened_iterator, actually defining a subclass. The enabled code doesn't use them, but provides some initialization. The change to disabled code defines a backward iterator for filtered flattened curve segments. Actually we define two ones : gx_flattened_iterator__prev_filtered1 - filters points with 'coords_near' gx_flattened_iterator__prev_filtered2 - filters points with 'coords_near' and 'gx_check_nearly_collinear'. The forward and the backward iterators are made to enumerate same points, which the old does while flatteining a curve. The old code has a lot of anomalies, therefore the backward iterators appear very coplicated. We're planning to drop the compatibility and simplify the iterators after the curved trapezoid algorithm passes the compatibility test. The compilation mode CURVED_TRAPEZOID_FILL0_COMPATIBLE 1 is not completed. Do not use it with this revision. EXPECTED DIFFERENCES : None.[src/gx.h 1.25, src/gxfill.c 1.65, src/gxfill.h 1.10, src/gxpflat.c 1.23, src/gzpath.h 1.22]

This is the first pass at the changes to support the PDF 1.5 revisions to the PDF format. DETAILS: The PDF 1.5 revision to the PDF specification contains two major additions to the format of a PDF document. Objects can be encoded in compressed data streams called and object streams. Xref tables were also changed to allow the identification of objects in object streams and also to allow the compression of xref tables. Together these changes reduced the size of the PDF 1.5 specification from 13.5 MB (PDF 1.4 version) to 8.7 MB (PDF 1.5 version). pdf_main.ps and pdf_rbld.ps - The changes in these modules were for the support of compressed XRef tables. The major part of these changes consist of the refactoring of readxref into pieces. One piece identifies the old format versus compressed XRef tables. A second piece supports the reading of old format XRef tables. The procedure readpdf15xref was added to read compressed XRef tables. A new larray called ObjectStream was added for identifying the location of objects which are inside a compressed object stream. The changes for the addition of ObjectStream also affect pdf_base.ps. pdf_base.ps - The procedures resolveR and resolved? had to be extended to support the presence of the objectstream type. A new procedure called resolveobjectstream was added for resolving objects inside of object streams. The code listing below has two versions of the resolveobjectstream procedure. I want to keep a record of both versions of this procedure in CVS. The first version is theoretically more robust than the second. It unpacks and processes objects from an object stream one at a time. To insure that this occurs, it creates a string of the exact size of an object and then unpacks and processes the object. However it is also very slow. Processing of a test document (PDF 1.5 spec.) with this routine is 4 times slower than processing a version of the PDF 1.5 spec. which does not use object streams. The second version of the procedure unpacks the entire object stream and then processes each object. Thus any problem which occurs with one object could, in theory, affect another object. The second version is much faster. There is about a 4% penalty for processing the compressed version of the PDF 1.5 spec. After the initial check in, the first version of resolveobjecstream will be removed unless some need is found for its robustness.[lib/pdf_rbld.ps 1.5]

Fix MSVC debug targets: add explicit makefile specification. Fix bug 687205. DETAILS: Debug targets have always been broken on Windows because nmake by default looks for "MAKEFILE" and fails. Until recently, the default target was built without the -O2 flag and could be used for debugging. This patch adds the correct filename explicitly to the debug target so it can be used instead.[src/msvc32.mak 1.52]
Fix a premature closedevice leading to a SEGV when a setpagedevice follows a setdevice with the only reference to the device in the graphics state. Bug #687204 detected with ps2epsi.ps. DETAILS: the ps2epsi.ps sets an image device, then does a .setsafe which uses setpagedevice to set .LockSafetyParams. Eventually setpagedevice results in a call to gs_setdevice_no_init, but the reference count to the current device is 1 so even though the device is not being changed, the device was being closed (which freed the buffer and line pointers). Usually the currentdevice reference count is > 1 since there is more than one gstate containing a pointer to the device. This has been broken since 8.10 when version 1.19 was released with some changes to device finalization. Note that ps2epsi.ps is extremely fragile and still doesn't work with examples/alphabet.ps after the patch (due to the "clear cleardictstack alphabetsave restore" logic at the end. This patch is ONLY for the SEGV. IMO, ps2epsi really is a mess and needs to be scrapped and designed properly.[src/gsdevice.c 1.20]

Fix .gethalftone to prevent /undefinedresource or other error from being left in the $error dict. Seen with UnusualFontMatrix.ps when running under startjob encapsulation. DETAILS: Internal procedures like .gethalftone that want to use stopped but don't propagate the error up should use .internalstopped since this doesn't set /newerror in $error. The file mentioned has a 'quit' following the showpage which when running under job encapsulation (false 0 startjob) is redefined to do 'stop'. This means that the /newerror flag in $error was being seen when the 'stop' after the showpage was executed.[lib/gs_init.ps 1.103]

Fix : The flattening algorithm inaccurately filtered points. Bug 687154 "Bugs in gx_flatten_sample". DETAILS : The old algorithm has 2 problems, which persist since March 20, 2000 or later : 1. When points buffer overflows, it doesn't filter the next point with MERGE_COLLINEAR_SEGMENTS. 2. With sn_not_first the first point was duplicated, and the last one was missed.

Fix incorrect handling of the '\' escape character in the filenameforall implementation on Windwows. Fixes bug #687151. Also fix logic in the .scanfontdir that relied on the incorrect filenameforall implementation. DETAILS: The previous NT filenameforall implementation did not translate the template string to be used by the FindFirstFile Windows call. This meant that the template was being passed the '\' escape characters which were not correctly handled by the OS call. Also testing -sFONTPATH=\Winnt\Fonts showed that this was also broken in gs_fonts.ps since it didn't duplicate the '\' characters for the template to filenameforall. Note that other gp_* implementations of file enumeration don't seem to handle escapes such as gp_unifs.c. The gp_macio.c doesn't do anything, and the gp_dosfe.c (deprecated) seems totally broken. The gp_os2.c appears to be a clone of the gp_ntfs.c, so should be fixed. About the only version that seems to be handling the '\' character according to the PLRM is gp_vms.c (can you believe that?).

Simplify the filtering of points while flattening a curve. DETAILS : This change is algorithmically equivalent due to algebraic laws. Thesis : (coord_near(x2, x0) && coords_in_order(x0, x1, x2)) implies coord_near(x2, x1). Proof: case 1: x0 >= x1 >= x2 ==> abs(x2 - x1) <= abs(x2 - x0); case 2: x0 >= x1 >= x2 ==> abs(x2 - x1) <= abs(x2 - x0); Therefore coord_near(x2, x1) doesn't need to check and has been removed. Same for Y. Then merged 2 branches with '||' because they appear same. The performance slightly increases, and the behavior is easier to understand. EXPECTED DIFFERENCES : None.[src/gxpflat.c 1.15]

Generalize the trapezoid filling algorithm for curves, step 6. DETAILS : This change modifies a disabled code, and includes a minor change to the enabled code, which should be algorithmically equivalent. In the enabled code factored out the new function add_y_line_aux. This patch fixes the dropout problem in CURVED_TRAPEZOID_FILL 1. The problem was unprocessed horizontal segments of curves. Now we create a new temporary horizontal line for each horizontal segment of a curve, and add it to the Y list. Then it immediately goes to H list, and then processed and freed. Due to the modification of the Y list during the main trapezoid loop (which did not happen before) the cycle commented with /* Move newly active lines from y to x list. */ is improved with providing a consistency of local copies of the Y list pointers. Good tests for this stuff present in a.pdf . With this patch with ppmraw 72dpi it renders equal to with CURVED_TRAPEZOID_FILL 0 code.

Generalize the trapezoid filling algorithm for curves, step 5. DETAILS : This change modifies a disabled code only. This patch provides more compatibility of the CURVED_TRAPEZOID_FILL & FLATTENED_CURVE_ITERATOR0_COMPATIBLE build to the old code. Doing it with implementing the new function gx_flattened_curve_iterator__prev. We're not planning to pass this function to production because it slows down. Only reason is to simplify testing with exact comparison of results of the old and the new code. The macro CURVED_TRAPEZOID_FILL_SCANS_BACK helps to remove it later. A new field skip_points is inserted into active_line_s for same purpose. While enumerating curve segments in a backward order, it helps to skip same division points as the old code does in the forward order. This thing consumes too much RAM. It won't go to production. One problem is left unsolved. While flattening a curve, it can generate a horizontal segment. It must be passed to h-list for dropout prevention. It is not done yet. This problem causes a dropout in a Chinese glyph in a.pdf with ppmraw 72 dpi. For a while we don't apply CURVED_TRAPEZOID_FILL for non-characters. The reason is that pco_monotonize works imprecisely. Will improve someday. Most characters are free of non-monotonic curves, but we notices a number of such in Genoa tests and in other files. The fragment INTERTRAP_STEM_BUG is an attempt to improve a serif suppression while dropout prevention. The coded condition isn't perfect. It is disabled. A better way would be to depend on Y projection contiguity, checking sect->y0, sect->y1. Keeping it to simplify further experimenting.

Fix (pdfwrite) : Type 1,2 composite glyphs could point to wrong subglyphs. DETAILS : This is a continuation of the recent patch for Bug 687172 "Jaggies appearing for some characters". The old code converted subglyph names to char codes with the font's Encoding. However arguments of 'seac' command always encode glyphs by StandardEncoding. If the fon't Encoding specifies different codes, the result was wrong. Since the font copying routine uses gs_glyph values taken from the global interpreter's space (see gsccode.h), which are PS name indices, it needs to convert a glyph name string to a name index. Before now we had no support for this. To provide it we add a new graphics library callback gs_font_dir::global_glyph_code. A recommendation for PCL interpreter : if it is called with pdfwrite, zfont_global_glyph_code to be implemented. Maybe an implementation with gs_c_known_encode helps. There exists a connected minor problem (PS interpreter only), which this patch doesn't fix. If a font is freed and then reloaded, the glyph names can get different name indices, if a garbager is invoked and freed the names before the second loading. As the result, the copied font can embed duplicated glyph definitions (charstrings). It can't give an invalid PDF, but it's size may increase. Hopely this case is rare. Opening a new bug 687187 about this. EXPECTED DIFFERENCES : None with comparefiles.[src/gsfont.c 1.28, src/gxfcache.h 1.22, src/gxfcopy.c 1.39, src/lib.mak 1.152, src/zfont.c 1.10]

A new virtual functions can_handle_hl_color() is required for high-level devices derived from gx_device_vector.
The library client api now propagates device_close errors to the return value of gsapi_exit().
Correct a long standing problem that caused non-optimized builds with MSVC on Windows. The default TDEBUG was 1, which circumvented a change made to msvccmd.mak to enable /O2 for MSVC_VERSION != 5.

Generalize the trapezoid fillling algorithm for curves, step 4. DETAILS : This change modifies a disabled code only. The comment /* Likely a bug in the !CURVED_TRAPEZOID_FILL code. */ is now removed because it is wrong. The function process_h_list performs that check perfectly. EXPECTED DIFFERENCES : None.[src/gxfdrop.c 1.5]

In the autoconf build, add the general cflags generated by the configure script to the definition the the definition of CCAUX. This works around a problem building on cygwin. DETAILS: Older versions of cygwin do not provide stdint.h but do define some of the types in sys/types.h. More recent versions do provide the header but also define them by inclusion in sys/types.h. This caused a problem with the 'fixup' code we added in response to bug 687162 which defined the missing half of the types if stdint.h was not detected by the configure script. In versions of cygwin that do provide stdint.h, most files compile as expected, but genconf.c is compiled with the alternate CCAUX compiler definition and was not receiving the -DHAVE_STDINT_H argument from configure, causing a type conflict between the complete set of stdint types pulled in by sys/types.h and the platform-specific fixup set included when stdint.h is supposedly not available. Adding the GCFLAGS line to the definition of CCAUX works around the problem and has little potential to confuse the build in the future. A similar change made to unix-gcc.mak would need to document the -DHAVE_STDINT_H option for cygwin. I felt this was unecessarily excessive; we already recommend the autoconf build on systems that can support it.[src/Makefile.in 1.28]

Fix : an access to uninitialized data in zbfont.c . DETAILS : Type 11 fonts got an occasional indeterministic data to pdata->Encoding, which were inaccurately checked for r_size() <= 256. We're keeping the check "r_size(pfe) <= 256" for backward compatibility, rather we're unclear about it's purpose. It shouldn't be harmful.

Fix (type 1 hinter) : sbw was wrongly accounted with FontBBox over 4095 units. DETAILS : Side bearing and width was accounted before import_shift is adjusted to FontBBox. Bug 687156 "some characters shifted higher in acrobat4 generated eps". Besides that, it prevents a fixed overflow when FontBBox is zero and glyph coordinates are big. Bug 687175 "(type 1 hinter) A fixed overflow can happen". This patch removes import_shift and the dependence on FontBBox. Instead that it dynamically reduces the number of fraction bits in transformation matrices during the glyph import. Minor change : removed some obsolete comments.
