	value if the actual value does not fit in an 'int'.
	* coders/jp2.c (BlobWrite): For old libJasper, return 0 for size
	value if the actual value does not fit in an 'int'.

	* magick/command.c (MagickCommand): Eliminate duplicate utility
	name output in error messages when utility is executed via a
	magick compatibility link.  For example via symbolic link from
	'convert' to 'gm'.  This problem was added when the initial batch
	mode implementation was submitted.  Addresses SourceForge issue
	#727 "convert convert" in error messages.

	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

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>

	* magick/module_aliases.h: Add missing module aliases "PNG00",
	"PNG48", "PNG64".

2023-08-31  Fojtik Jaroslav  <JaFojtik@yandex.com>

	* coders/bmp.c: BMP with 2bpp is a legal BMP variant.
	https://en.wikipedia.org/wiki/BMP_file_format Quote: "The 2-bit
	per pixel (2bpp) format supports 4 distinct colors and stores 4
	pixels per 1 byte, the left-most pixel being in the two most
	significant bits (Windows CE only)."

	Partial revert: BITMAPV2INFOHEADER: RGB bit field masks,
	BITMAPV3INFOHEADER+: RGBA
	The opacity channel handling is even more complex.

2023-08-29  Fojtik Jaroslav  <JaFojtik@yandex.com>

	* coders/bmp.c: First attempt to read BMP with BI_JPEG compression
	inside.

2023-08-28  Fojtik Jaroslav  <JaFojtik@yandex.com>

	* coders/bmp.c: Remove code duplicity and evaluate BiCompression
        only on one place.

2023-08-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/attribute.c (GetImageInfoAttribute): For the "name" key,
	return the input file base name, until reason is found to do
	otherwise.

	* magick/utility.c (TranslateTextEx): Restore previous
	functionality in which a NULL pointer is returned instead of an
	empty string. Some algorithms are depending on this!  Addresses
	SourceForge issue #722 v1.3.41 "PerlMagick montage.t fails
	completely".

2023-08-23  Fojtik Jaroslav  <JaFojtik@yandex.com>
	
	* VisualMagick\installer\inc\files-dlls.isx
	* VisualMagick\installer\inc\body.isx
	
	Prepare installation script for MSVC2013 runtime.

2023-08-22  Fojtik Jaroslav  <JaFojtik@yandex.com>
	
	* VisualMagick\installer\inc\files-dlls.isx
	* VisualMagick\installer\inc\body.isx
	
	Prepare installation script for MSVC2010 runtime.

2023-08-21  Fojtik Jaroslav  <JaFojtik@yandex.com>

	* coders/bmp.c: When alpha is to be used, writer must not use
	BI_BITFIELDS compression that instructs to strip alpha.

2023-08-20  Fojtik Jaroslav  <JaFojtik@yandex.com>

	* tiff/libtiff/stdbool2.h MSVC2010 does not have stdbool.h nor inttypes.h

2023-08-16  Fojtik Jaroslav  <JaFojtik@yandex.com>

	* coders/bmp.c: Populate upper byte to lower byte even for lower
	bpp than 8. It overcomes quantum scalling error in gm. Code should
	be redesigned, but it is better than previous state.

	Enforce default color masks when bmp_info.compression==BI_RGB
	Existing masks will be ignored.

2023-08-17  Fojtik Jaroslav  <JaFojtik@yandex.com>

	* coders/bmp.c:  Enforce default matte for 40 byte header & 32bpp.

2023-08-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (ReadTIFFImage): For common formats with the
	required number of channels, but one is an 'unspecified' channel,
	promote unspecified alpha to unassociated alpha so that the alpha
	channel is not ignored. Addresses the remainder of SourceForge
	issue #718 "Set reasonable defaults when writing TIFF with
	transparency".

2023-08-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am (CHANGELOGS): Changelogs ChangeLog.2021 and
	ChangeLog.2022 where missing from the distribution.

	* coders/tiff.c:  Fix compilation problem in MSVC.

2023-08-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (WriteTIFFImage): Default the alpha channel to
	type EXTRASAMPLE_UNASSALPHA(2).  The default was
	EXTRASAMPLE_UNSPECIFIED(0), which is particularly unfortunate
	given that GraphicsMagick 1.3.41 now silently ignores such
	channels. Patch by Markus Mützel.  Addresses SourceForge issue
	#718 "Set reasonable defaults when writing TIFF with
	transparency".

2023-08-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* NEWS.txt: Updated for 1.3.41 release.

	* coders/tiff.c (ReadTIFFImage): Fix garbled logic pertaining to
	photometric checks.  Addresses Coverity 393177 "Structurally dead
	code".

	* coders/heif.c (ReadHEIFImage): For libheif versions <
	0x01090000, ignore_transformations is always 1. Add a conditional
	check to avoid Coverity 384803 "Logically dead code" for old
	versions.

	* coders/identity.c (ReadIdentityImage): Check the return value
	from AllocateImageColormap().  Addresses Coverity 384802
	"Unchecked return value".

	* magick/utility.c (ExpandFilename): sysconf() can return a
	negative value (e.g. -1).  Verify that the value is greater than 0
	before using it.  Addresses Coverity 384798 "Out-of-bounds
	access".

2023-08-09  Fojtik Jaroslav  <JaFojtik@yandex.com>

2023-08-08  Fojtik Jaroslav  <JaFojtik@yandex.com>

	* coders/bmp.c: Data behind declared BMP header should not be read.
	It could poison newly converted image with garbage.

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

	* coders/cineon.c (GenerateCineonTimeStamp): Correct strlcpy()
	length arguments so they are based on the actual destination
	buffer size.  Based on a report from Dirk Müller
	<dmueller@suse.de> that the test suite does not pass with the new
	glibc 2.38 (which finally provides strlcpy()/strlcat()) due to a
	fortify assertion.

2023-08-08  Fojtik Jaroslav  <JaFojtik@yandex.com>

	* coders/bmp.c: CI chunk must have biSize only 12 or 40.

2023-08-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (ReadTIFFImage): Default field pass count to 1
	since "Unsupported" tags return two arguments.

2023-08-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* jp2/src/libjasper/include/jasper/jas_types.h: MSVC 17.6.5 needs
	the _PFX_PTR definition.

	* coders/bmp.c (ReadBMPImage): Fix GCC 13.1.0 warning about
	quantum_bits being possibly used while uninitialized.  I don't see
	how that is possible based on current logic, but avoid the
	warning.

	* magick/gem.c (ExpandAffine): Mark as a pure function.

2023-07-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* fuzzing/oss-fuzz-build.sh: Fix typo which breaks oss-fuzz build.

	* coders/jxl.c (WriteJXLImage): Port forward to latest development
	0.9.0 API, which removes unused pixel_format from
	JxlDecoderGetColorAsEncodedProfile(),
	JxlDecoderGetICCProfileSize(), JxlDecoderGetColorAsICCProfile()
	and silently drops JXL_ENC_NOT_SUPPORTED.

2023-07-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* fuzzing/oss-fuzz-build.sh: Add --disable-ifunc to xz build
	options to avoid segmentation violation, matching options
	successfully used by ImageMagick's oss-fuzz build.

2023-07-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/attribute.c: In GetImageClippingPathAttribute(), check
	for the presence of the clipping path name (ID=2999). If that's
