GraphicsMagick ChangeLog

2024-04-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

www/contribute.rst: Remove mention of needing a formal maintainer for the Gentoo Linux GraphicsMagick ebuild, since there has been an excellent maintainer for a long time already.

configure.ac: Remove use of wrong == syntax. Much thanks to Sam James for the patch.

2024-04-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

doc/options.imdoc: Update the documentation regarding WebP exact mode, and the new --version option.

coders/webp.c (WriteWEBPImage): Add support for '-define webp:exact=true' to preserve exact RGB values under transparent areas while writing WebP format. Enable this automatically when lossless is enabled. If lossless is enabled, this option may be used to disable exact mode. Addresses SourceForge issue #737 "WebP: Colors not preserved in fully-transparent areas".

2024-04-12 Fojtik Jaroslav <JaFojtik@yandex.com>

coders/png.c:

magick/describe.c: Reveal opacity presence.

2024-04-11 Fojtik Jaroslav <JaFojtik@yandex.com>

coders/tga.c: Write correctly TGA with opacity values in palette.

2024-04-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/module_aliases.h: Only include module alias when there is a module to support it.

magick/deprecate.c: Add a comment about magick monitor constant string specification deprecations.

2024-04-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/tga.c: Fix Coverity issues 424688 and 424689, which are due to inconsistent use of LogMagickEvent().

2024-03-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

utilities/tests/version.tap: New test script to exercise version output.

utilities/tests/help.tap: Skip 'batch' help since its help output contains TAP syntax, which confuses the test.

magick/command.c: Add support for a --version option, which produces GNU style summary version output.

2024-03-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/version.h.in: Copyright year is 2024!

2024-03-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2024-03-17 Fojtik Jaroslav <JaFojtik@yandex.com>

2024-03-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

VisualMagick/tests/runtest.bat: Remove tests for format identifiers which are not even images, or require special add-on software, or could otherwise not work.

tests/constitute.c: Handle capital 'Y' and 'K' while checking if a CMYK map is specified.

VisualMagick/tests/run_constitute.bat: Re-generate test script based on what current tests/constitute.tap does.

VisualMagick/bin/log.mgk: Change default configuration to be suitable for 'console' apps with working 'stderr', such as used by the test suite.

2024-03-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

NEWS.txt: Update the news.

www/api/types.rst: Fix spelling errors and out-of-date information in types.rst. Resolves SourceForge patch #80 "Update types.rst documentation".

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.

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.

2024-02-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2024-02-25 Fojtik Jaroslav <JaFojtik@yandex.com>

coders/tiff.c: Do not copy TIFFTAG_ORIENTATION from EXIF. It is already handled by image->orientation variable.

coders/tga.c: Emit warning to logs when orientation is not supported. FIED: Need to research what case was expected to be tested here. This test case can never be true and so it is commented out for the moment.

2024-02-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/tga.c (WriteTGAImage): Eliminate compiler warnings.

2024-02-24 Fojtik Jaroslav <JaFojtik@yandex.com>

VisualMagick/configure/configure.rc: Disable static single threaded runtime choice. This runtime is not suported in Visual Studio 2008 and all newer versions.

2024-02-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/psd.c: If module gets built, but EnableBrokenCoders is not true, then include empty registration functions.

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.

coders/hrz.c (RegisterHRZImage): Set 'seekable_stream' and 'adjoin' correctly.

2024-02-18 Fojtik Jaroslav <JaFojtik@yandex.com>

jpeg/*: Update JPEG builtin library to 9f.

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!

2024-02-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/jpeg.c (WriteJPEGImage): Do some preparation to implement support for libjpeg-turbo 3.X APIs while writing deep JPEG.
