2013-12-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/alpha_composite.h (BlendCompositePixel): Fix from Troy Patteson to eliminate induced color problems when compositing two images which include fully transparent pixels. Now fully transparent pixels do not contribute any color to the composed result. Opacity used when blending is now based on the average opacity of both pixels. Resolves SourceForge issue #148 "Pixel interpolation problem with rotated transparent images ".
2013-12-18 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>
coders/png.c (ReadOnePNGImage): Properly scale 16-bit input PNG down to 8-bit when using a Q8 build.

coders/webp.c (ReadWEBPImage): Support 'ping'. Improve quality of error reporting.
GraphicsMagick.spec.in: Update RPM spec file to add libwebp-devel as a build dependency, and libwebp as a run-time depdendency.
2013-12-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/webp.c: Incorporated simple WebP support as contributed by "TIMEBUG" at users.sf.net plus a few security changes. Does not yet support Windows Visual Studio build, input from a pipe, attached profiles, animation, or incremental pixel I/O. (RegisterWEBPImage): Register WebP as requiring seekable stream so input from pipe works.
2013-11-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
wand/drawing_wand.c (DrawSetStrokeDashArray): Use array size specified by user and don't expect user-provided array to be terminated by 0.0. Resolves SourceForge bug "#250 Unexpected results from DrawSetStrokeDashArray".

wand/drawing_wand.c (DrawGetStrokeDashArray): terminating 0.0 to array returned to user.
magick/draw.c (DrawGetStrokeDashArray): Add terminating 0.0 to array returned to user.
2013-11-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/annotate.c (RenderFreetype): Support rendering UTF-8 21-bit code points. Was limited to 16-bit code points due to an oversight/bug. Resolves SourceForge bug "#149 Rendering UTF-8 encoded file displays wrong glyphs".
2013-11-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/constitute.c (ReadImage): Consistently initialize Image page width and height to image width and height. Resolves SourceForge bug #253 convert pdf output page is the wrong size with -geometry "100%".
2013-11-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/tiff.c (WriteTIFFImage): TIFFDefaultStripSize() sometimes returns zero so make sure that rows-per-strip is at least one to avoid divide by zero error. This bug was added in the current development cycle.
2013-10-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
NEWS.txt: Update news since last release.
magick/annotate.c (RenderFreetype): Support Johab, Latin-1, and Latin-2 encodings.
2013-10-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
wand/drawing_wand.c (DrawSetStrokeLineJoin): BevelJoin should produce MVG text "bevel".
magick/draw.c (DrawSetStrokeLineJoin): BevelJoin should produce MVG text "bevel". Fixes SourceForge bug "#245 error occured to DrawableStrokeLineJoin(LineJoin.BevelJoin)".
2013-10-16 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>
Added calls to png_set_benign_errors() to allow benign errors to be handled as warnings. In particular, GM builds with libpng-1.6.x will not crash while copying a PNG with a "known incorrect ICC profile".
2013-10-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/nt_base.c (NTGhostscriptEXE): Use gswin64c.exe as Ghostscript executable name in a 64-bit application.
2013-10-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/nt_base.c (NTGhostscriptFind): 64-bit application should not search for Ghostscript in 32-bit registry. SourceForge bug #243 "GM on Windows will find Ghostscript only if both are 32 bit"
2013-09-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/pnm.c: As an extension to the standard PNM and PAM formats, support writing 32-bit sample depth in the Q32 build, and supporting reading 32-bit sample depth in all builds.
2013-09-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/tiff.c: Allow reading signed integer TIFF files even though internal storage uses signed integers. Negative values will be handled incorrectly and positive values will be scaled to only 1/2 of the available unsigned range. Perhaps the situation will improve in the future.
tests/rwfile_miff.tap: Test MIFF with specific depths.
tests/rwblob.c: Add support for -quality option.
tests/rwfile.c: Add support for -quality option.
tests/rwfile.tap: Add tests for PGM and PPM ASCII subformats.
coders/pnm.c (WritePNMImage): PGM "P2" format writer was broken at 8-bit depth due to lack of white-space between the output values. Fixed now.
2013-09-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/miff.c (ReadMIFFImage): Fixes to be able to read MIFF written by ImageMagick 6.X, including DirectClass grayscale images. Interoperabilty is not completely assured since ImageMagick is not consistent with itself and may only be able to read the file it just wrote. Reading DirectClass grayscale RLE compressed images is not supported yet.
2013-09-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/profile.c (MagickFreeCMSTransform): Only delete the CMS transform if it is non-null. If lcms returned a null transform, an assertion was thrown in lcms when the pointer was freed. Problem was reported by James Bardin.
2013-09-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/miff.c: PseudoClass format was written incorrectly in that sample storage size is supposed to be selected based on the size of the colormap, but it was being selected based on the depth parameter instead, leading to excessively sized files and failure to read what was written. RLE compressed formats had the sense of the alpha channel inverted from the other compression methods, and contrary to the specification. PseudoClass with Alpha was not supported at all, and reading a file claiming to be such caused an assertion to be thrown. Note that these fixes may cause some existing files to no longer be read correctly.
coders/xpm.c (ReadXPMImage): XPM is rarely used to produce 16-bit output. Set image depth based on the colormap.
coders/tim.c (ReadTIMImage): PSX TIM is not able to produce more than 8-bit output, set image depth appropriately.
2013-09-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/tiff.c (WriteTIFFImage): Increase rows-per-strip as required to try to avoid more than 32K strips per image since some programs seem to use a 16-bit strip counter and fail with more than 32K strips. Problem was reported by Kevin Myers.
magick/transform.c (MosaicImages): Fix unsigned underflow problem with -mosaic when page offset is negative and exceeds image width or height. This problem caused assertions, out of memory errors, or pixel cache limit errors due to requesting an image of outrageous size.
dcrawdcraw.c Updated from autor
dcrawdcraw.c.patch
2013-08-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/pnm.c (ReadPNMImage): Fix SourceForge issue #237 "Incorrect MAXVAL scaling when reading PAM images".
2013-08-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/render.c (DrawImage): Improve error handling so that rendering bails on image access/update errors. Resolves SourceForge issues #233 "Another SVG that hangs GraphicsMagick" and #232 "Another SVG that hangs GraphicsMagick". The resolution of the bug is to return from image access/update error right away rather than adjusting the rendering density to produce a smaller image.
magick/error.h: Hide exception throwing convenience macros under MAGICK_IMPLEMENTATION definition.
Magick++/demo/demos.tap: Fix file naming for 'zoom' demos.
magick/annotate.c (RenderFreetype): Improve error handling so that rendering bails on image access/update errors.
2013-08-02 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>
coders/png.c (ReadOnePNGImage): ping a png faster by returning the image without reading the pixel data.
2013-07-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/xwindow.c (MagickXMakeImage): Only use ThumbnailImage() for DirectClass images in order to avoid a crash while creating the panner image.
2013-04-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
design/pixel-cache-struct.dot: Update structure relationships diagram.
design/pixel-cache.dot: Update call flow diagram.
magick/pixel_cache.c: Eliminate use of internal functions GetNexusIndexes(), GetNexusPixels(). Reduce usage of internal function IsNexusInCore().
2013-04-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
configure.ac: MAGICK_SSIZE_T should always be a signed type.
coders/jpeg.c (WriteXMPProfile): Add support for writing 'XMP' profile in JPEG. (WriteJPEGImage): Restructure/tidy JPEG profile writing code.
2013-04-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/tiff.c (ReadTIFFImage): Return DirectClass images by default for MINISWHITE and MINISBLACK TIFF formats.
2013-04-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/wpg.c, magick/attribute.c, magick/map.c, magick/render.c, magick/widget.c, magick/xwindow.c: Fixes to reduce warnings with GCC 4.8.0 at -O3 optimimization level, and for clang 3.2.
2013-04-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/xwindow.c (MagickXMakeImage): Use ThumbnailImage() rather than SampleImage() when creating the panner image to improve the quality of the image.
2013-03-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/attribute.c (tag_table): Add support for SubjectArea EXIF tag. Resolves SourceForge issue #229 "Cannot Parse the SubjectArea EXIF Info".
2013-03-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
www/Hg.rst, www/index.rst: Update SourceForge Mercurial repository location (see http://hg.code.sf.net/p/graphicsmagick/code) due to project "upgrade". For the moment there are old and new repositories. Changes will be pushed to the new repository.
2013-03-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/resource.c (InitializeMagickResources): Revert use of omp_set_dynamic() since it caused a severe performance regression when doing a -stepthreads benchmark or when the number of OpenMP threads is set via OMP_NUM_THREADS.
2013-03-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
INSTALL-unix.txt: Add a section about building Windows binaries by cross-compiling from a Unix/Linux system.
2013-03-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
configure.ac, magick/magick_types.h.in: Fix issues noticed when cross-compiling with MinGW64.
2013-03-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
version.sh, www/index.rst: Prepare for 1.3.18 release.
2013-03-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/command.c (DisplayImageCommand): display is supposed to respond to +/-usePixmap, but was not. It was responding to +/-use_pixmap. Now it responds to both.
2013-03-03 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>
doc/GraphicsMagick.imdoc: Relocated some <im> .. </im> tags, to include several paragraphs that were omitted from the GraphicsMagick man page (Environment, Configuration Files, and Copyright).
doc/imdoc2man: the </pre> tag was being deleted instead of replaced with nothing, which caused the first line of the subsequent material to be joined to the last line of the <pre> block.
2013-03-02 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>
coders/png.c (ReadOnePNGImage): Avoid a libpng16 warning about storing unknown chunks.
2013-02-25 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>
coders/png.c (WriteOnePNGImage): Call png_set_bKGD(), etc., after png_set_IHDR() because they depend on members of info_ptr which are set by png_set_IHDR().
2013-02-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/resource.c (InitializeMagickResources): Enable the dynamic adjustment of OpenMP threads if there is more than one thread available.
2013-02-18 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>
configure.ac and configure: Check for libpng17 and libpng16.
2013-02-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
www/programming.rst: Add mention of Clement Farabet's Lua scripting language wrapper for GraphicsMagick.
2013-02-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/pixel_cache.c (GetCacheNexus): Re-write function so it has a single point of return. (AcquireCacheNexus): Reduce the number of return points. (SetCacheNexus): Re-write function so it has a single point of return.
2013-02-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
NEWS.txt: Update with latest news.
magick/export.c (ExportAlphaQuantumType): Fix export of alpha for RGBA image and depth 8. Due to typo, was exporting 16-bits rather than 8, causing output corruption or crashes. Resolves issue reported in SourceForge GraphicsMagick forum under title "CMYK per-channel byte order TIFF crashes gm".
2013-02-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/studio.h (MagickIsBlank): Add macro to substitute for ISO C99 isblank() which is not globally available. Update 'gm batch' code which had substituted isspace() for isblank() to use it.
2013-01-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/command.c (BatchCommand): Flush stdout at key points in order to ensure that user sees text when it is produced.
2013-01-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/random.c (InitializeMagickRandomGenerator): Use MagickTsdKeyCreate2() in order to avoid a small memory leak.
magick/tsd.c (MagickTsdKeyCreate2): New private function to support allocating a thread-specific data key with a specified destructor function. For single-threaded build, MagickTsdKey_t is now type void* and there is provision to support the destructor function.
2013-01-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/command.c (BatchCommand): New 'gm batch' command to accept one or more GraphicsMagick commands from a specified text file, standard input, or CLI. Feature is implemented by Kenneth Xu. Submitted via SourceForge Patch #3602331 "Add interactive or batch mode support to 1.3.17".
2013-01-27 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>
coders/png.c (WriteOnePNGImage): Added PNG48 and PNG64 support. Added PNG00 support (png encoder that inherits its color-type and bit-depth from the input, if the input was a PNG datastream).
2013-01-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
coders/png.c (WriteOnePNGImage): PNG8 support was using image->colors to decide if the input image is PseudoClass. This is totally bogus. Use image->storage_class to determine if image is PseudoClass and quantize image colors if it is not.
magick/delegate.c (InvokePostscriptDelegate): Only invoke MagickSpawnVP() if Ghostscript filename argument is non-empty. This argument may be empty if Ghostscript is not found on a Windows system. Report a "Failed to find Ghostscript" error if the Ghostscript command name is empty. Resolves SourceForge issue #3601816 "Win64 build crashes trying to convert PDF to any other format".
magick/utility.c (MagickSpawnVP): Verify that file argument is non-NULL and not empty.
2013-01-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
VisualMagick/tiff/LIBRARY.txt: Fix pre-processor definitions for libtiff so that they use multiple statements rather than one long statement. Resolves SourceForge issue 3601001 "libtiff won't compile with ICL".
2013-01-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/memory.h (MagickAllocateAlignedArray): New macro to wrap use of MagickMallocAlignedArray().
magick/memory.c (MagickMallocAlignedArray): New private function to support safe allocation of an array in memory with a specified alignment. Allocation may only be freed using MagickFreeAligned() and the allocation may not be reallocated.
2013-01-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
magick/{animate.c,display.c,utility.c}: Only invoke chdir() if path is not an empty string. Previously sometimes chdir() was passed an empty string (because chdir() was not needed) and this was ok because we ignored the error status. Now that we check the chdir() error status, some X11 GUI functions (e.g. save file to current directory) encounter annoying issues.
magick/shear.c (IntegralRotateImage): Limit integral rotate to two threads.
coders/pnm.c (ReadPNMImage): Limit PNM reader to two threads.
2013-01-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
configure.ac (MAGICK_FEATURES): MinGW static build does not build modules so MODULES feature should not be listed as supported. Resolves MinGW test failures.
coders/dpx.c (OrientationTypeToDPXOrientation): Return U16 type as stored in DPX format.
coders/cineon.c: Add support for reading/writing 'orientation' setting.
coders/mpc.c: Add support for reading/writing 'orientation' setting.
coders/miff.c: Add support for reading/writing 'orientation' setting.
