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".

2012-03-17 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.

> - 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.
