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".

2012-03-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (ConvertImageCommand, MogrifyImageCommand): Added support for '+noise random' and '-operator noise-random' to 'convert' and 'mogrify'.
> - magick/effect.c (AddNoiseImage): Added support for RandomNoise. (AddNoiseImageChannel): Added support for RandomNoise.
> - magick/enum_strings.c (StringToNoiseType): New function to convert a string to a NoiseType enumeration value. (NoiseTypeToString): New function to convert a NoiseType enumeration value into a string.
> - PerlMagick/Magick.xs: Added support for RandomNoise.
> - magick/operator.c (QuantumOperatorRegionImage): Added support for RandomNoise.
> - magick/effect.c (AddNoiseImageChannel): Added support for RandomNoise.
> - magick/gem.c (GenerateDifferentialNoise): Added support for RandomNoise.
> - magick/random.h (MagickRandomRealInlined): The span of MagickRandomRealInlined() is now slightly more accurate.
> - magick/image.h (enum NoiseType): New enumeration value RandomNoise.

2012-03-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (MogrifyImage): Add support for -repage option to composite, convert, mogrify, and montage subcommands. Resets or adjusts the current image page offsets based on a provided geometry specification.
> - magick/image.c (ResetImagePage): Add a function to adjust the current image page canvas and position based on a relative page specification.

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

> - magick/command.c (MogrifyImage): Add support for -strip option to composite, convert, mogrify, and montage subcommands. Removes all profiles and text attributes from the image.
> - magick/image.c (StripImage): New function to remove all profiles and text attributes from the image.

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>

> - tiff: Update bundled libtiff to 4.0.1 release.
> - png: Update bundled libpng to 1.5.9 release.
> - magick/memory.h: Decorate memory allocation functions with GCC attribute 'alloc_size'.
> - magick/common.h: Add support for GCC 4.3+ attributes 'alloc_size', 'hot', 'cold'.
> - 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.

2012-02-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - png: Updated to libpng 1.5.8 release
> - zlib: Updated to zlib 1.2.6 release

2012-02-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Makefile.am (AUTOMAKE_OPTIONS): Update to Automake 1.11.3. Add lzip compressed archive to options.

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.

2012-01-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - www/OpenMP.rst: Updated OpenMP results based on latest OpenMP tunings and the Intel Xeon E5649 CPU.

2012-01-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/dcraw.c (ReadDCRAWImage): Fix memory leak of ImageInfo. 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>

> - magick/gem.c (Hull): Improve performance.
> - magick/effect.c (DespeckleImage): Improve performance.

2012-01-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/effect.c (DespeckleImage): Using schedule(static,4) blocks any opportunity for speedup. This was a performance regression. Oops!

2012-01-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - wand/magick_wand.c (MagickExtentImage): Added MagickExtentImage() to Wand API. Resolves SourceForge issue #3471915 "MagickExtentImage in the Wand C API".

2012-01-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/export.c (ExportViewPixelArea): Break up implementation into subroutines to ease compilation.

2012-01-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/import.c (ImportViewPixelArea): Break up implementation into subroutines to ease compilation.

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

> - magick/studio.h: Use Magick prefixed macro names for ftruncate, mmap, and munmap in order to assure that introducing our macros does not cause trouble with system headers.
