GraphicsMagick ChangeLog - 2023

2023-12-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• NEWS.txt: Update the news as of December 30, 2023.

• magick/resource.c (_UpdateMagickResourceHighwater): New private function to support updating highwater values where it otherwise does not naturally happen. The highwater values represent the result of successful requests so they may be used to evaluate the resource limit requirements of a particular request.

• magick/resource-private.h: New header file to contain private definitions pertaining to resource allocation.

2023-12-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• magick/resource.c: Add a resource 'highwater' value which is updated to the maximum resources used for that resource type. This value is currently only reliably updated for SummationLimit LimitType. Trace the highwater values when resource tracing is enabled.

2023-12-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• NEWS.txt: Update the news as of December 28, 2023.

• configure.ac: fixup LFS check for autoconf-2.72. Patch by Sam James <sam@gentoo.org>.

  For the 'other' case, we were using the value of ac_cv_sys_file_offset_bits for -D_FILE_OFFSET_BITS to pass down into the Perl module build, but autoconf-2.72 drops the use of ac_cv_sys_file_offset_bits in cf09f48841b66fe76f606dd6018bb3a93242a7c9, so this ends up defining '-D_FILE_OFFSET_BITS=' which then breaks the build.

  I've just added a hack to preserve the old behaviour to avoid passing a blank value.

2023-12-27 Fojtik Jaroslav <JaFojtik@yandex.com>

• tiff/: Update libtiff to 4.5.1.

2023-12-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• coders/heif.c (ReadHEIFImage): Support setting image width limit.

• configure.ac: Check libheif for heif_context_set_maximum_image_size_limit().

• coders/jxl.c: Improve JXL reader/writer exception information.

2023-12-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• NEWS.txt: Update with news since the last release.

2023-12-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• coders/jbig.c (ReadJBIGImage): Attempt to set maximum image dimensions based on resource limits before calling jbg_dec_in() so it will quit on excessively large images. This often works, but not all the time.

2023-12-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• fuzzing/oss-fuzz-build.sh: Add -DJPEGXL_ENABLE_SKCMS=false to libjxl build since skcms is not working with static linkage.

• configure.ac: Try really hard to configure everything, even if pkg-config is not present or misbehaves. If pkg-config is not present, it may be necessary to manually set CPPFLAGs in order to find the FreeType and libxml2 headers. Also print any error information that pkg-config produces. jxl_threads is not a hard requirement. Do not search for TRIO by default. The user needs to specify --with-trio=yes in order to enable searching for TRIO.

• coders/: Updated the many coders to behave correctly when faced with an unexpected write error.

• magick/blob.c: If the write limit is hit, then the truncated output file is automatically removed.

2023-11-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• config/delegates.mgk.in, VisualMagick/bin/delegates.mgk: Re-direct Ghostscript stdout to stderr to avoid output corruption when GM stdout is redirected to a file. Addresses SourceForge issue #729 "GhostScript warnings in files on stdout".

2023-10-21 Fojtik Jaroslav <JaFojtik@yandex.com>

• coders/wpg.c: Do not touch to image structure from palette reader. "RecordLength" is a 32bit variable, it should not be long that expands to 64bits.

2023-10-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• magick/command.c (CommandAccessMonitor): Add "Access Request: " to the printed access request message.

• magick/effect.c (AddNodeMedianList): Make sure that 'update' is initialized.

• magick/colorspace.c: primary_info x,z are float so use floating point math to compute them.

• coders/wpg.c: Avoid signed/unsigned compare warning

• Many files: Add casts to prevent unnecessary value truncation in WIN64 build.

Addresses oss-fuzz issue 63335: "graphicsmagick:coder_WPG_fuzzer: Use-of-uninitialized-value in GrayscalePseudoClassImage". This is a stop-gap fix until the WPG reader supports a colormap independent of the image, to be used when needed.

2023-10-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• coders/tiff.c (WriteTIFFImage): Remove safe-guards against use of incorrect PHOTOMETRIC_MINISWHITE or PHOTOMETRIC_MINISBLACK photometic for Group3 and Group4 compression.

• coders/wpg.c (ReadWPGImage): Add a FIXME comment for a bug yet to be fixed.

• PerlMagick/t/png/read.t: Add a test case for BMP with embedded PNG. Something is still wrong given that reading using PerlMagick is returning two frames rather than one.

• magick/pixel_cache.c: Update documentation to reflect that GetImagePixels() has been deprecated since 2008, and update mention of it to document use of AccessMutableIndexes() or AccessImmutableIndexes().

• coders/pnm.c (ReadPNMImage): Add traces prior to each decoding loop to identify the sub-format being decoded.

• coders/bmp.c (ExtractNestedBlob): Pass pointer to image list to satisfy requirements of AppendImageToList() and DeleteImageFromList().

• coders/sun.c (WriteSUNImage): Test for sun_info.length overflow in a way which should not provoke a compiler warning.

2023-09-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• VisualMagick/magick/magick_config.h.in: Block building the XTRN coder unless the user enables EnableXTRNCoder. The XTRN coder is primarily used by the optional contributed ImageMagickObject COM+ DLL object, but it might be used for a similar purpose. The XTRN coder serves no purpose unless invoked from the address space of a program using GraphicsMagick.

2023-09-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• tests/{constitute.c, drawtest.c, rwblob.c, rwfile.c}: Initialize locale settings the same as the 'gm' utility.

2023-09-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• NEWS.txt: Updated the News.

• magick/attribute.c (SetImageAttribute): Disable attribute extension deprecation warning printf. It may be that eliminating support for attribute value extension will never happen due to subtly entrenched internal usage.

• coders/pnm.c (ReadPNMImage): Fix reading comments from PAM format.

2023-09-06 Fojtik Jaroslav <JaFojtik@yandex.com>

• coders/bmp.c: Reverting to BI_BITFIELD. BI_ALPHABITFIELDS seems to be very rare.

2023-09-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• coders/wmf.c (ipa_draw_text): Treat pointer inputs as if they may be NULL. Change live printfs to traces. Adjust white-space in whole module to current conventions. Addresses SourceForge issue #724 "Old WMF display: assert fails in draw.c", although I am unable to reproduce it.

2023-09-05 Fojtik Jaroslav <JaFojtik@yandex.com>

• coders/bmp.c: Sorry for a previous commit. After some investigations it seems that bit field masks are behind header when BI_SIZE=40.

2023-09-04 Fojtik Jaroslav <JaFojtik@yandex.com>

• coders/bmp.c: Default bit split for older BMPs with 32bpp and BI_BITFIELDS set is crazy. Verified against IrFanView and bmpsuite-2.7.zip - image g/rgb32bf.bmp.

2023-09-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• magick/resize.c (ResizeImage): Restore vertical/horizontal filter order decision logic which was in place before the 1.3.41 release since it may result in tiny changes to low order bits in 16-bit/sample images, which may be concerning to some. Resolves SourceForge issue #723 "montage result differ between 1.3.40 and 1.3.41". The provided test-case showed that the filter filter order changed from "Vertical/Horizontal" to "Horizontal/Vertical".

2023-09-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• magick/command.c (MogrifyImage): Use MaxRGBDouble double constant rather than integral MaxRGB as argument to StringToDouble().

2023-09-01 Fojtik Jaroslav <JaFojtik@yandex.com>

• coders/bmp.c Bitmap header with size 52 bytes is also valid.

2023-08-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
