    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.

  - 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>

    SetImageAttribute() Extending attribute value text code entirely.

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>

    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>

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>

    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>

  - 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

    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>

    the \_PFX\_PTR definition.

  - coders/bmp.c (ReadBMPImage): Fix GCC 13.1.0 warning about
