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.

2012-09-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - tiff: Update libtiff to 4.0.3 release.

> - lcms: Update liblcms2 to 2.4 release.

> - png: Update libpng to 1.5.13 release.

2012-09-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - 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.

2012-08-06 Fojtik Jaroslav <JaFojtik@seznam.cz>

> - coders/jnx.c: Image cache is turned off to work-around memory overflow.

2012-08-05 Fojtik Jaroslav <JaFojtik@seznam.cz>

> - 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>

> - magick/command.c (MogrifyImage): -units was adjusting existing 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".

2012-05-01 Fojtik Jaroslav <JaFojtik@seznam.cz>

> - coders/mat.c Animated movies inside 4D matrices are loaded now.

2012-04-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/pixel_iterator.c: Limit the number of threads to use in the loop rather than the total number of threads available.

2012-04-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Release GraphicsMagick 1.3.15

2012-04-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/image.c (SetImageInfo): Remove automatic adjoin mode support logic. (AddDefinition): Fix use of uninitialized variable.

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>

> - coders/pnm.c (ReadPNMImage): Completely disable OpenMP in reader because there is too much contention.

> - magick/pixel_iterator.c: Dereference image to be modified in non-threaded context in order to lessen contention.

> - magick/semaphore.c (AllocateSemaphoreInfo): Make sure that 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.

> - wand/magick_compat.c (ParseGeometry): Use strlcpy() rather than strncpy(). (CopyMagickString): Depend on strlcpy() because we provide it if it is missing. (ConcatenateMagickString): Depend on strlcat().

> - 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".

2012-02-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Release GraphicsMagick 1.3.14.

> - NEWS.txt: Updated to describe updates since last release.

2012-02-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Downgrade to Automake 1.11.2 so that test suite can run on 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.

2012-02-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/{log.h,monitor.h,utility.h}: Use double-underscore syntax in GCC format attribute specifications to defend against accidental macro expansion.

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

> - coders/xcf.c (ReadXCFImage): Fix reading XCF which is comprised of different sized layers.

2012-02-08 Glenn Randers-Pehrson <glennrp@simplesystems.org>

> - coders/txt.c: Added "-define txt:with-im-header" option.

2012-01-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/dcraw.c (RegisterDCRAWImage): Add support for Mamiya Photo RAW "MEF" format. Resolves SourceForge issue #3481508 "*.MEF file open incorrect".

2012-01-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - 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 endianness so that the endianness of the original file is preserved by default. The user is able to override this default via -endian. Problem was reported by JongAm Park.
