2012-12-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/command.c: Added -auto-orient to 'convert' and 'mogrify'
    to automatically rotate the image upright for viewing based on its
    current orientation setting.
    Added -orient to support setting the image orientation.

  - magick/shear.c (AutoOrientImage): New function to automatically
    orient the image so that it is upright for normal viewing.

2012-12-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - scripts/tap-functions.shi: Tidy TAP tests so that they may be
    run alone, or via Perl's 'prove'.

2012-12-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - tests/rwfile.c (main): Test file name generation was not
    correct.

2012-12-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - tests/rwfile.tap: Added -stdio tests for most file formats.
    This tests I/O using an already-opened file handle passed via the
    ImageInfo file member.  Formats using the Ghostscript delegate are
    not working right yet.

2012-12-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - tests/rwfile.c (main): Added a '-stdio' option to test
    reading/writing files using file handles opened by the API user.

  - magick/blob.c (CloseBlob): It should be possible to invoke
    CloseBlob() multiple times, including blobs set to "exempt".
    There were some issues when passing in file descriptors.

2012-12-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - www/api/api.rst: Add another example Core C API example program.

  - magick/blob.c (OpenBlob): Restore file position, rather than
    rewind, after reading header bytes.

  - magick/image.c (SetImageInfo): Restore file position after
    reading header bytes.  Resolves SourceForge issue 3597486
    "ReadImage not working with file descriptors".

2012-12-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - VisualMagick: WIN64 (64-bit Windows) installer improvements to
    bring up to par with 32-bit installer.

2012-12-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - VisualMagick: WIN64 (64-bit Windows) is supported now.

2012-12-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/blob.c: Eliminate support for experimental
    MAGICK\_MMAP\_WRITE, which never quite worked correctly and did not
    provide performance benefits.

2012-12-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/blob.c (FileToBlob): Rewrite to be based on stdio.

2012-12-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/magick\_types.h.in: Changes to try to work better with the
    Windows WIN64 API.

2012-12-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/image.c (SetImageColorRegion): The provided color should
    be in the same colorspace as the image.  The image is no longer
    converted to RGB with the expectation that the provided color is
    always some particular RGB.
    (AppendImages): No longer transform the canvas image to RGB.  Now
    append uses the first listed image to determine the colorspace
    which should be used when appending the additional images and of
    the output image.  The additional images are converted to the
    canvas image colorspace.  Likewise, the background color is
    assumed to be in the same colorspace as the first listed image so
    that it is compatible and can be used to fill the background color
    without translation.

2012-11-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - rungm.sh.in: Remove extraneous space in first line which
    prevents execution with T-shell (tsch).  Reported by William
    Langdon.

2012-11-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - www/wand/wand.rst: Add a simple example of using the Wand API.

2012-11-21  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

  - coders/bmp.c (ReadBMPImage): Fixed an old bug with decoding
    chromaticity primaries.

2012-11-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - wand/magick\_wand.h ("C"): Need to include wand/wand\_symbols.h
    after magick/api.h in order for options from magick\_config.h to
    take effect.

  - magick/symbols.h (PSPageGeometry): Fix typo. Should map to
    GmPSPageGeometry.

2012-11-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - wand/wand\_symbols.h, magick/symbol.h: MagickWand API is now
    prefixed with 'Gm' when the --enable-symbol-prefix configure
    option is supplied.  These changes are contributed by Ben Wu.
    Details of changes are as follows:

    1. A new header file wand/wand\_symbols.h which prefixes all
       MagickWand API symbols with Gm.
    2. Modification to all the header files in wand/ to include
       wand\_symbols.h.
    3. Modification to magick/symbols.h to include additional
       symbols which were colliding with names in ImageMagick.
    4. Modification to magick/error.c to exclude function
       definitions for MagickError, MagickFatalError,
       MagickWarning, and ThrowException when building with
       --enable-symbol-prefix option. There four names were also
       defined as macros so it appears that putting them in a
       symbol-remapping file wont work.

  - Makefile.am: Update Automake to 1.12.5.

2012-11-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - Magick++/COPYING: Change Magick++ usage license to be exactly
    the MIT license without the additional sentence about retention of
    copyright (which was already legally implicit).

2012-11-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/symbols.h: Re-generate list of symbols to prefix.

  - magick/utility.c (IsGlob): IsGlob can be more efficient.

  - magick/floats.c: Use compile-time selection of endian-specific
    code rather than run-time.  Fix cast warning with 64-bit builds.

2012-11-07  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

  - coders/png.c (WriteOnePNGImage): The wrong QuantumType was
    sometimes passed to ExportImagePixelArea() by the PNG encoder.

  - coders/png.c (ReadOnePNGImage): Let libpng unpack all sub-8-bit
    pixels (see change of 2012-08-31 which lets libpng unpack sub-8-bit
    palette images; this also lets libpng unpack the grayscale images).

  - coders/png.c (ReadOnePNGImage): Corrected the reading of interlaced
    images (see SourceForge bug 3420695, in which all passes are
    displayed in a garbled manner instead of only the completed image).

2012-10-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - wand/magick\_wand.c (MagickGetImagePage): Need to use 'image'
    rather than 'images' in order to work with iterator.
    (MagickSetImagePage): Need to use 'image'
    rather than 'images' in order to work with iterator.

2012-10-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/utility.c (TranslateTextEx): Fix bug with input string
    read overrun if the input string ends with a single '%'.  This
    sometimes caused random heap data to be added to the output string
    until another null character is reached.  A simple work-around
    without this fix is to use "%%" rather than "%".  Fixes
    SourceForge bug 3580219 "strange results with '%' in Annotate()".

2012-10-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - wand/magick\_wand.c (MagickSetImagePage): New method to support
    setting the image page size and offsets.
    (MagickGetImagePage): New method to support getting image page
    size and offsets.

2012-10-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - configure.ac: Report fatal error if doing modules build and
    libltdl is not found.

2012-10-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - ltdl: Libltdl is no longer bundled.  Libltdl must be previously
    installed on the system in order to build the modules
    configuration.

2012-10-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - www/index.rst: Update top index page for 1.3.17 release.

  - NEWS.txt: Update NEWS for 1.3.17 release.

  - version.sh: Update shared library versioning for 1.3.17 release.

  - coders/jnx.c: Fix format string compilation warnings.  Remove
    MS-DOS line terminations.

  - configure.ac: Module loading is now only supported by the
    modules build and not just because shared libraries are enabled.
    This means that libltdl is only depended upon by the modules
    build.  Sometime in the future, libltdl will no longer be bundled
    in the GraphicsMagick source tree.

2012-10-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - configure.ac (LTDL\_INIT): Request installable libltdl rather
    than convenience.

2012-10-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/bmp.c: Support alpha channel in uncompressed 32-bit BMP.
    Resolves SourceForge issue 3566239 "Can't open BMP with alpha
    created by photoshop".

2012-10-07  Fojtik Jaroslav  <JaFojtik@seznam.cz>

  - dcraw/dcraw.c: Fixed situation when M\_PI is not defined.

2012-10-07  Fojtik Jaroslav  <JaFojtik@seznam.cz>

  - coders/jnx.c: Add image attribute with geolocation.

2012-10-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - dcraw: VisualMagick configure fixes to support linking with JPEG
    and JPEG2000.

2012-09-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - dcraw: Add dcraw to VisualMagick build.

  - libxml: Update libxml2 to 2.9.0 release.

  - Makefile.am: Update to Automake 1.12.4.

2012-09-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - doc/options.imdoc: Fix Debian bug 687738 "graphicsmagick:
    repeated words suitable for suitable for in gm manpage" reported
    by Jonas Smedegaard.

2012-09-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - NEWS.txt: Update with news since last release.

  - configure.ac: Added the configure option
    --enable-quantum-library-names to enable that shared library name
    includes quantum depth to allow shared libraries with different
    quantum depths to co-exist in same directory (only one can be used
    for development).

2012-09-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/effect.c (AdaptiveThresholdImage): New implementation
    contributed by Roberto de Deus Barbosa Murta.  Executes in linear
    time as threhold area is increased rather than being quadratic.

2012-09-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/svg.c: Fix improper injection of XML headers as rendered
    text.

  - magick/render.c (DrawImage): Fix SourceForge issue 3499164
    "Drawing of text fails if text starts with "," character".  Fix
    SourceForge issue 3411492 "Certain SVGs hang GraphicsMagick".  Fix
    SourceForge issue 1961000 "Could not print ',' via convert draw
    text".

2012-09-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/wmf.c (lite\_font\_stringwidth): Simply return zero.
    Returning a computed string width was causing text placement
    problems when testing with libwmf's fulltest.wmf.

2012-08-31  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

  - coders/png.c: ReadOnePNGImage: sub-8-bit palette images were
    getting unpacked twice; once by libpng via png\_set\_packing()
    and again by coders/png.c in a switch() statement around line 2500,
    resulting in horizontally stretched pixels.

2012-08-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - Makefile.am (AUTOMAKE\_OPTIONS): Include lzip as a distribution
    format again.

2012-08-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - configure.ac: BrowseDelegate now defaults to 'xdg-open', but if
    it is not found, then configure will search for firefox,
    google-chrome, mozilla (in that order).

2012-08-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - configure.ac: For testing on MinGW, assume that Postscript is
    available since we don't have a good way to check for that.

  - scripts/tap-functions.shi (test\_count): Always execute the test
    program rather than skipping execution since we want to make sure
    the test program fails correctly as well.

  - coders/gif.c (DecodeImage): Add a log message for attempted LZW
    string data table overflow.

2012-08-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/effect.c (ConvolveImage): Allocate normalized convolution
    kernel using cache-line aligned memory allocator.

  - configure.ac: Remove support for legacy LZWDecodeDelegate and
    LZWEncodeDelegate since these are not used any more.

2012-08-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - scripts/tap-functions.shi: If a test declares that it needs
    certain features, skip the test if required features are not
    available.

  - configure.ac: Build a supported features list and save to
    common.shi script for use by test scripts.

  - Makefile.am (LOG\_COMPILER): Run Bourne-shell based TAP scripts
    with the same shell $(SHELL) that configure selected for the
    Makefile to use.

2012-08-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - Makefile.am (AUTOMAKE\_OPTIONS): Update to Automake 1.12.3.
    Update test suite to use Automake TAP driver rather than legacy
    tests.

2012-08-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/jnx.c (ExtractTileJPG): Add a trace of tile offset and size.

2012-08-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/jnx.c (ExtractTileJPG): Use a memory buffer for the JPEG
    tile rather than a temporary file.

2012-08-12  Fojtik Jaroslav  <JaFojtik@seznam.cz>

  - PerlMagick/t/input\_jnx.jnx: Small JNX test file.

2012-08-11  Fojtik Jaroslav  <JaFojtik@seznam.cz>

  - coders/jnx.c: speedup.

2012-08-10  Fojtik Jaroslav  <JaFojtik@seznam.cz>

  - coders/jnx.c: changed malloc/free to MagickMalloc/MagickFree.

2012-08-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/jnx.c (ReadJNXImage): Add progress monitor support for
    JNX.

  - coders/jnx.c: Fixed.

2012-08-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/jnx.c: Add JNX coder for "Garmin proprietary Image
    Format" (implementation by Jaroslav Fojtik) to the build.  Code is
    not yet working properly at this time.

2012-08-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - configure.ac: Remove use of -Wl,-zlazyload under Solaris since
    it seems to decrease the stability of C++ exceptions in x86-64
    build and does not measurably improve runtimes.  Don't force use
    of liblzma because libtiff is used.  User should always have
    control.

2012-07-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/memory.c (MagickMallocAligned): Use RoundUpToAlignment()
    macro to compute aligned pointer.

  - magick/effect.c (EnhanceImage): Eliminate use of ugly Enhance
    macro.  Only filter based on color channels (ignore opacity).

2012-07-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/studio.h (MAGICK\_CACHE\_LINE\_SIZE): Assume a cache line
    size of 64 bytes except for on PowerPC which uses 128.

  - magick/pixel\_cache.c: Use aligned memory allocator to allocate
    structures and buffers which might suffer from false cache line
    sharing

  - magick/memory.c (MagickMallocAligned): Also round up allocation
    size to alignment.

2012-07-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/effect.c, magick/random.c, magick/semaphore.c: Use
    aligned memory allocator to align allocations which should be
    aligned to cache line boundary.

2012-07-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/memory.h (MagickAllocateAlignedMemory): New macro to
    allocate aligned memory.
    (MagickFreeAlignedMemory): New macro to free aligned memory.

  - magick/memory.c (MagickMallocAligned): New internal function to
    allocate aligned memory.
    (MagickFreeAligned): New internal function to free aligned memory.

2012-07-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/common.h (MAGICK\_ASSUME\_ALIGNED): Add some GCC attribute
    wrappers for useful features added by GCC 4.7.

2012-07-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/gif.c (ReadGIFImage): Try to be better about reporting
    failure when ReadBlob() fails to return the requested number of
    bytes.

2012-06-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - www/benchmarks.rst: Strip the outdated benchmark results from
    the benchmarks page.

  - magick/command.c (ImportImageCommand): Status returned from the
    command was inverted.

2012-06-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - Release GraphicsMagick 1.3.16

2012-06-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

    resolution the wrong way around.

2012-06-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - jpeg: Updated to IJG 8d release.

  - libxml: Updated libxml to 2.8.0 release.

  - zlib: Updated zlib to 1.2.7 release.

  - magick/blob.c (MagickFileHandle): Refer to stdio, bzip2, and
    gzip file handles using their own type.  Eliminates warnings
    observed when compiling with zlib 1.2.7.

  - tiff: Updated libtiff to 4.0.2 release.

  - png: Updated libpng to 1.5.11 release.

2012-06-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - configure.ac: Fix typo which caused the --without-lzma option to
    be handled incorrectly.  Resolves SourceForge issue 3535309
    "graphicsmagick from 1.3.13 to 1.3.15 has broken lzma support".

2012-06-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - tests/rwfile.c (main): Verify that we can 'ping' the file using
    PingImage().  Tests for some formats may take longer to complete.

  - tests/rwblob.c (main): Verify that we can 'ping' the blob using
    PingBlob().  Tests for some formats may take longer to complete.

  - coders/xbm.c (ReadXBMImage): Fix memory leak of temporary X
    bitmap image allocation encountered when reading in 'ping' mode.

  - magick/blob.c (PingBlob): Re-write to be based on BlobToImage()
    so that it works reliably.
    (BlobToImage): Restore original input file name to image if
    temporary file was used so that image 'filename' and
    'magick\_filename' do not contain unexpected content due to using a
    temporary file.

2012-06-07  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

  - coders/png.c: Disable new libpng-1.5.10 test for invalid palette
    index when reading a PNG or MNG (for speed), or when writing a MNG
    (because a zero-length PLTE is valid in a MNG).

2012-06-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/attribute.c (SetImageAttribute): Don't translate
    'comment' and 'label' attributes if the request is made while a
    file is being read.  This is a temporary workaround until there is
    opportunity to modify the architecture so that there is a clear
    split between user-provided settings and values obtained from the
    input image.

  - magick/blob.c (GetBlobIsOpen): New function to return if blob is
    currently open.

2012-06-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - PerlMagick/typemap: Add typemap file needed by Perl 5.16.
    Resolves SourceForge issue 3531512 "PerlMagick does not build with
    perl 5.16".

2012-05-29  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

  - coders/png.c: Ignore APNG chunks even if we are using a libpng
    that was built with the "APNG patch".

2012-05-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/command.c (ConvertImageCommand): +repage does not require
    an argument.  Resolves SourceForge issue 3529158 "+repage option
    not respected with convert command".

  - configure: Update to Autoconf 2.69.

  - magick/effect.c (MotionBlurImage): Motion blur does scale so
    remove DisableSlowOpenMP for it.

  - magick/command.c (BenchmarkImageCommand): Remove parenthesis
    from output, and change "iter/sec cpu" to "iter/cpu" to ease
    parsing.

  - magick/pixel\_cache.c (GetPixelCacheInCore): Consider read-only
    memory-mapped cache as being "in-core".  Otherwise MPC input files
    are penalized.

2012-05-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/api.h: Include <sys/types.h> on POSIX systems in order to
    help assure that 'size\_t' and 'ssize\_t' are declared.

2012-05-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/magick\_config\_api.h.in: Need to provide definitions for
    'size\_t' and 'ssize\_t' in case the system headers lack these types
    because the definition of MagickExtentImage() requires them.  This
    should resolve PHP bug #62034 "gmagick does not compile".

2012-05-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/pixel\_iterator.c (GetRegionThreads): Don't thread region
    if it is not memory-based.

2012-05-09  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

  - coders/png.c (ReadOnePNGImage): make transparent\_color elements
    unsigned long instead of unsigned short, so 65537 is actually out of
    range as expected, and won't match any pixel if no tRNS chunk is
    present.

2012-05-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/sfw.c (ReadSFWImage): Reader needs to be more robust
    against corrupt or maligned headers.  Resolves SourceForge issue
    "sfw file crash".

2012-05-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/pdf.c (WritePDFImage): Add file basename as the PDF
    document title.  Resolves SourceForge bug ID 2835140
    "GraphicsMagick fails to add title attribute to PDF output".

  - coders/sfw.c (ReadSFWImage): Restore original filename and
    format.

  - PerlMagick/t/jpeg/read.t: Add a test for reading Seattle
    FilmWorks format based on the sample image from
    http://www.algonet.se/~cyren/sfw/.  Image was approved for
    distribution in GraphicsMagick by Bengt Cyrén.

  - magick/analyze.c (GetImageBoundingBox): Only apply opacity-based
    bounding box detection if all three test points are non-opaque and
    the same value.  Resolves SourceForge bug ID 3522804 "convert
    -trim fails on 8-bit PNG that ImageMagick can trim".

  - coders/sfw.c (ReadSFWImage): Fix variety of bugs related to
    closing Image and blob at wrong points.  SFW reader is working
    again.  Resolves SourceForge bug ID 523430 "sfw file open failed".

2012-04-23  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

  - doc/\*.imdoc: some example commandlines in the documentation
    were missing the leading "gm ".

2012-04-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/blob.c (FormMultiPartFilename): No longer add a
    printf-style scene formatting specification to filenames which do
    not have one and no longer automatically operate in 'adjoin' mode
    in such cases.  This is a BIG CHANGE for users who may have become
    used to this automatic functionality.  The simple solution to
    update existing scripts depending on this behavior is to change
    any bare filenames to include a format specification similar to
    "image-%d.jpg" and add +adjoin to the command line.  The reason
    why this change is made is that the output files produced by any
    given operation were unpredictable, and it was causing temporary
    files to be leaked due to the renaming.

2012-04-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/bmp.c (WriteBMPImage): Enforce that image width and
    height do not exceed BMP dimensions.  BMP dimensions are
    represented by a signed type.  BMPv2 supports maximum dimensions
    of 32k by 32k.

2012-04-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/info.c (WriteINFOImage): When driven by the 'convert'
    utility, -format produces user-controlled formatted output similar
    to -format in 'identify'.  This is accomplished via a
    'info:format=value' define.

  - magick/image.c (AddDefinition): New function for adding just one
    define to definitions list.

2012-04-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

    SemaphoreInfo does not share cache lines with another semaphore.

2012-04-11  Glenn Randers-Pehrson  <glennrp@simplesystems.org>

  - coders/png.c: fixed problem with bit depth when the encoder
    decides to write RGBA instead of indexed PNG, by delaying the
    call to png\_set\_tRNS() until after calling png\_set\_IHDR().

2012-03-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - png: Update bundled libpng to 1.5.10 release.  Provides security
    fix for CVE-2011-3048.

  - coders/xcf.c (ReadXCFImage): Now respects image subimage and
    subrange members so that returned image layers may be selected.
    Based on patch from SourceForge issue 3513025 "XCF reads all
    layers all the time".

  - magick/resize.c (ThumbnailImage): Thumbnail default filter is
    intended to be the box filter, but allow the user to override the
    filter used.  Resolves SourceForge issue 3513239 "-filter command
    line argument ignored".

    systems with limited command line length.  This means that lzip
    support is temporarily removed.

  - magick/resize.c (ResizeImage): Resize filter argument was being
    ignored.  Filter from image 'filter' member was used instead.
    Problem was reported by Steven Bakhtiari.

  - coders/jpeg.c (WriteJPEGImage): Convert RGB-compatible
    colorspaces (e.g. CineonLog) to RGB by default since that was the
    case prior to release 1.3.13.  User can still override it
    (avoiding removal of log encoding) by explicitly specifying the
    desired colorspace.  Problem was reported by Gary Margiotta.

2012-01-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/dpx.c (ReadDPXImage): When reading, save input file

    Resolves SourceForge bug #3475148 "memery leaks".

  - magick/module.c (ModuleAliases): EMF format is supported by EMF
    module and so mapping EMF to the WMF module caused EMF not to
    work.  Resolves SourceForge bug #3475147 "emf files can not be
    opened".  Note that the EMF module only works for Microsoft
    Windows.

2012-01-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
