2024-10-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
fuzzing/oss-fuzz-build.sh: Set libheif ENABLE_MULTITHREADING_SUPPORT to off to see if it causes an abort in std::terminate to go away.
2024-10-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/gem.c (Hull): More fixes for regression created by Mercurial changeset 16913:78aa63677935 "Add casts to prevent unnecessary value truncation in WIN64 build" on Saturday, October 21, 2023.
TclMagick/generic/TclMagickAppInit.c: Refresh implementation based on latest code from reference tcl/unix/tclAppInit.c.
2024-10-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
TclMagick/Makefile.am: Eliminate the libttkcommon "shim" library which allowed TkMagick to work and use a different approach. TclMagick is not dependent on libtk. Only TkMagick is dependent on libtk.
2024-09-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
www/links.rst: Update oss-fuzz bug tracker URL.
2024-09-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/gem.c (Hull): Fix regression created by Mercurial changeset 16913:78aa63677935 "Add casts to prevent unnecessary value truncation in WIN64 build" on Saturday, October 21, 2023.

2024-09-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
TclMagick/Makefile.am: Now uses non-recursive build and produces xz tarball. The make 'distcheck' target is not working properly yet. (AM_DISTCHECK_CONFIGURE_FLAGS): Change the argument to --exec-prefix so that 'make distcheck' now passes.
2024-09-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/display.c (MagickXROIImage): ThresholdCommand was missing from EffectsCommands list. In the Region of Interest mode the button command array is missing a command corresponding to "Threshold...", and that is also messing up all buttons further below. SourceForge patch #82 "Add missing Threshold to command array of Region of Interest mode" by Alex Barsky.
TclMagick/generic/config.h.in, TclMagick/generic/libttkcommon.h: Support a configuration header.
TclMagick/configure.ac: Modernize Autoconf files.
TclMagick/Makefile.am: Modernize Automake files.
2024-09-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
TclMagick/generic/TclMagick.c: Fix several typos which will produce wrong results, as well as quieting fallthrough warnings.
2024-09-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
config/type-urw-base35-t1.mgk.in: Add a template file for the newer Artifex urw-base35-fonts, but for the Postscript Type 1 fonts. This is not integrated into the build and no substitutions are performed on it.
2024-09-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
config/type-urw-base35-otf.mgk.in: Changes for the newer Artifex urw-base35-fonts, which now support OpenType fonts, and use long file names. Specifically configure the location using the --with-urwbase35otf-font-dir configure option. This is in response to Debian bug 1019717 "Display of an SVG file broken due to gsfonts transition", https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1019717.
2024-09-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
configure.ac: Validate legacy Ghostscript font file in Ghostscript install directory before deciding to use it as the Ghostscript font directory.
2024-09-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/jxl.c (ReadJXLImage): Apply image dimension resource limits. Addresses oss-fuzz Issue 69728: "graphicsmagick:coder_TIFF_any_fuzzer: Out-of-memory in coder_TIFF_any_fuzzer".
2024-09-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
doc/options.imdoc: Further updates to color specification documentation, based on what the current code is doing. Unfortunately, current behavior deviates from CSS3 in some aspects.
fuzzing/oss-fuzz-build.sh: Libtiff build now requires autoconf-archive
2024-09-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
doc/options.imdoc: Remove mention of RRRRGGGGBBBBAAAA due to an interpretation conflict which causes it to not be supported. Add documentation for 32-bit variants. Addresses SourceForge issue #747 "#RRRGGGBBBAAA and #RRRRGGGGBBBB color names conflict".
2024-09-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
TclMagick/: White-space clean-up and consistent indentation.
2024-09-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
TclMagick/unix/m4/tcl.m4: Update tcl.m4 to TEA_VERSION 3.10. The TEA_INSTALLER Autoconf macro oddly does not use the settings set by AC_CONFIG_AUX_DIR to find install-sh. Instead it hard-codes $(srcdir)/tclconfig/install-sh. Change that hard-coded path to $(top_srcdir)/unix/config/install-sh.
TclMagick/generic/pkgIndex.tcl: Remove generated file.
TclMagick/generic: Regenerate Autotool's generated files with autoconf 2.71 and automake 1.16.5.
2024-08-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

version.sh: Updates in preparation for the 1.3.45 release.
2024-08-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
NEWS.txt: Update the news.
2024-08-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/fpx.c: Coverity fixes for "dead code" and an integer overflow issue.
magick/image.c (MagickParseSubImageSpecification): Fix SourceForge issue "#746 Off-by-one-error when converting PDF with multiple pages". Also add additional sanity checking. Unfortunately, this is a regression added in the 1.3.44 release.
2024-08-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
www/Changes.rst: 1.3.44 is released in 2024.

2024-08-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
NEWS.txt: Update the news.
2024-08-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/image.c (GetImageInfo): Change the default for ImageInfo 'progress' to False. This parameter is used by 'animate' and 'display'. It was discovered that under Ubuntu 22.04 LTS, the progress indication in 'animate' and 'display' has changed from almost no cost, to taking vastly more time than the work to be performed! As a result, there will be no graphical progress indication in the X11 commands unless this resource is set to True. ImageMagick had already removed this progress indication. The -monitor option will cause progress output to stderr.
2024-08-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
www/docutils-articles.css: reStructuredText style sheet adjustments to work with HTML 4 and 5 synax, by Mark Mitchell.
www/docutils-api.css: reStructuredText style sheet adjustments for HTML 5, by Mark Mitchell.
tests/rwfile.tap: Adjustments for FlashPIX tests.

coders/hrz.c: Tidy and clarify code.
2024-08-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
configure.ac, coders/dps.c: Display Postscript stopped being available after Sun Solaris 10 (if legacy Xsun was used rather than Xorg) and has been substantially gone from the world for a long time already since Oracle stopped supporting desktop systems not long after acquiring Sun in 2010. Remove support for Display Postscript. Ghostscript works better since it supports multiple pages whereas Display Postscript only supported one page.
config/{config.guess,config.sub}: Re-bootstrap with latest config.guess and config.sub.
2024-08-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
NEWS.txt: Update the news.
www/index.rst (https): Update Coverity statistics. Add mention of how ImageMagick has now removed classic utilities such as 'convert'.
www/INSTALL-windows.rst: Add a note regarding problems building UTIL_IMDisplay in some free Visual Studio versions, and how to fix it.
www/contribute.rst: Add another idea for contributing to GraphicsMagick.

coders/bmp.c (ReadBMPImage): Eliminate GCC 14 warning.
2024-07-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
configure.ac: Add LIB_FPX and LIB_GS back into the LIBS list. LIB_FPX was commented out long ago, but it seems that LIB_GS was accidentally dropped within the past year during the big re-write to depend more on pkg-config. These changes are due to SourceForge issue #745 "missing fpx library during linking".
2024-07-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/blob.c (MagickMaxFileSystemBlockSize): Place an artibrary limit on maximum filesystem block size.
coders/Makefile.am (MAGICK_ORA_MODULES): ORA module is dependent on HasLIBZIP.
2024-07-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/command.c (MogrifyImage): Change utility '-depth N' to a simple image depth attribute assignment rather than also being an image processing operation. Obtain the previous result (which immediately modified the image pixels) using '-operator All Depth N'. Most users use -depth in order to influence the bits/sample of the file being written rather than as an intermediate image processing operation.
magick/floats.c (_Gm_convert_fp32_to_fp24): Coverity fixes for arithmetic overflow in mantissa related code.
2024-07-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2024-07-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/tiff.c (InitializeImageColormap): Verify that TIFFTAG_BITSPERSAMPLE is within a rational range.
coders/gif.c (ReadGIFImage): Don't evaluate background color if image->colors == 0. Coverity did not detect that previous error handling would already have caught this issue.
coders/pnm.c (PNMInteger): Code simplification, and convince Coverity that value returned by ReadBlobByte() is positive if it is not EOF.
coders/txt.c (ReadInt): Convince Coverity that value returned by ReadBlobByte() is positive if it is not EOF.
coders/sct.c (ReadSCTImage): Convince Coverity that value returned by ReadBlobByte() is positive if it is not EOF.
coders/png.c (ReadMNGImage): Eliminate warning: variable 'loops_active' set but not used".
coders/pcd.c (DecodeImage): Eliminate "warning: variable 'count' set but not used".

www/INSTALL-unix.rst: Remove mention of the original MinGW which became dead and unusable at OSDN a couple of years ago. It is not even possible to download the installer program. The old version at SourceForge is all which remains working.
2024-07-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
configure.ac: Assume that targets matching *-w64-mingw* are capable of supporting 'C99 printf syntax. (INT64_F, UINT64_F, MAGICK_SIZE_T_F, MAGICK_SSIZE_T_F): Try to intuit better MinGW printf syntax based on host_vendor setting.
wand/pixel_wand.c (ClonePixelWands): Eliminate GCC 14 warning about MagickAllocateArray() argument order.
magick/magick.c (GetMagickInfoArray): Eliminate GCC 14 warning about MagickAllocateArray() argument order.

2024-06-24 Fojtik Jaroslav <JaFojtik@yandex.com>
VisualMagick/configure/configure.exe: Needs to be updated, because header files are hardcoded in it :(.
VisualMagick/configure/configure.cpp: dependency to core_rl_zlib_.lib is also configured in C source code - too bad!

2024-03-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
wand/magick_wand.c (MagickPingImage, MagickReadImage) (MagickReadImageBlob, MagickReadImageFile): AppendImageToList() now leaves the image pointer pointing to the end of the list. The Wand implementation expects that wand->images points to the begining of the list. Update wand->images to point to the beginning of the list. Resolves SourceForge issue #735 "[MagickWand] Potential regression when creating GIFs".
2024-03-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
utilities/Makefile.am: Give up on the attempt to selectively force C++ linkage by introducing a C++ file for components which should have C++ linkage. A libtool bug, and an Automake weakness prevented this from working as expected. (UTILITIES_CLEANFILES): Clean-up utilities/tests/composite_tmp.msl.

2024-02-22 Fojtik Jaroslav <JaFojtik@yandex.com>
VisualMagick/tests/runtest.bat: G,K and Y tests started to fail before several months without knowing why. Do not stop. Too bad. Added test for HRZ format.
2024-02-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
tests/{rwblob.tap, rwfile.tap}: Add HRZ to sanity checks.

2024-02-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/jpeg.c (FreeMagickClientData): Assure that jpeg_pixels is non-NULL before dereferencing it. Resolves oss-fuzz issue 66666: "graphicsmagick:coder_DCM_fuzzer: Null-dereference READ in ReadJPEGImage". This is an issue introduced by yesterday's submission.
2024-02-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/enum_strings.c (StringToCompressionType): Recognize "LosslessJPEG" as indicating LosslessJPEGCompression.
coders/jpeg.c (WriteJPEGImage): Added support for writing lossy or lossless 12 bits, and lossless 16-bits using libjpeg-turbo-3.0. Added the -define options 'jpeg:data-precision', 'jpeg:lossless-precision', and 'jpeg:lossless-predictor', to provide control over the parameters used. Please note that most applications do not support lossless JPEG compression (and only support a sample size of 8) so take care not to use these features if it not known that all involved software can support them!
