2014-05-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/operator.h ("C"): New quantum operators ThresholdBlackNegateQuantumOp and ThresholdWhiteNegateQuantumOp. These correspond to -operator "Threshold-Black-Negate" and "Threshold-White-Negate".

2014-05-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/composite.c (MultiplyCompositePixels): Multiply composition now uses SVG interpretation of how alpha should be handled. No longer does a simple multiply of alpha channel. Behavior change. Patch contributed by Sara Shafaei.
> - coders/msl.c (ProcessMSLScript): Deal with case where image_info->attributes is NULL.

2014-04-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/utility.c (TranslateTextEx): Support additional format specifiers 'g', 'A', 'C', 'D', 'G', 'H', 'M', 'O', 'P', 'Q', 'T', 'U', 'W', 'X', and '@'. (GetMagickGeometry): Support '>' and '<' qualifiers with '@' qualifier to specify if image should be resized if larger or lesser than given area specification. Resolves SourceForge bug #216 ">" wont take effect when use @ to specify the maximum area.
> - magick/transform.c (GetImageMosaicDimensions): Move mosaic dimensions code to a static function for possible future re-use.

2014-04-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/gradient.c (GradientImage): Update image is_grayscale and is_monochrome flags based on gradient color properties.

2014-04-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/utility.c (GetMagickGeometry): Deal with resize geometry missing width or height (e.g. '640x' or 'x480') by substituting the missing value with one which preserves the image aspect ratio. This has been documented to be supported since almost the dawn of GraphicsMagick but was not actually supported until now.

2014-04-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - doc/options.imdoc: Document WebP encoder options.
> - coders/webp.c (WriteWEBPImage): Support all of the WebP encoder options via -define arguments. Most of this work is contributed by Roman Hiestand.
> - configure.ac: User-provided LIBS should be prepended to LIBS that configure script produces so that user option takes precedence.

2014-04-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - PerlMagick/Magick.xs: Added support for HardLight composition operator.
> - www/perl.rst: Update PerlMagick documentation, including the composition operators.
> - coders/xcf.c (GIMPBlendModeToCompositeOperator): Use new HardLight composition operator to support XCF GIMP_HARDLIGHT_MODE blend mode. Contributed by Sara Shafaei.
> - coders/psd.c (CompositeOperatorToPSDBlendMode): Use new HardLight composition operator to support PSD "hLit" blend mode. Contributed by Sara Shafaei.
> - wand/magick_wand.c (MagickOperatorImageChannel): New function to apply an operator to an image channel. Contributed by Sara Shafaei.
> - magick/composite.c (HardLightCompositePixels): New HardLight composition operator. Contributed by Sara Shafaei.

2014-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (BenchmarkImageCommand): Add a CSV title line and quoting to benchmark -rawcsv output.

2014-04-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/webp.c: Add progress indication support to WebP writer.
> - magick/command.c (VersionCommand): WebP support is included in -version output.
> - coders/webp.c: WebP coder identifies library version and header ABI versions. Improve WebP error reporting.

2014-04-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/tiff.c (WriteTIFFImage): Allow specifying the TIFF image software tag. In the special case that the string length is zero (e.g. -set software '') then the tag is skipped entirely. This is to support SourceForge feature request #37 "Option to prevent addition of Exif Software tag" opened by Jean-Louis Grall. Please note that this tag is not an EXIF tag.
> - magick/command.c: composite, convert, display, mogrify, and import now support +set to remove an existing image attribute.

2014-03-16 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>

> - coders/png.c: Don't block threads when PNG_SETJMP_SUPPORTED is not enabled.
> - coders/png.c: Changed prefix of macros defined in coders/png.c from PNG_ to GMPNG_. PNG_ is reserved for macros defined by libpng.

2014-03-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/blob.c: Don't use setvbuf() to set stdio block size if filesystem block size is zero (e.g. MAGICK_IOBUF_SIZE=0)

2014-03-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - tests/{rwblob.tap, rwfile.tap}: Added tests for WEBP.
> - tests/{rwblob.c, rwfile.c}: Add lossy hint for WEBP.
> - coders/webp.c (WriteWEBPImage): Fix inverted return status. Added a tiny bit of logging.

2014-03-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - ttf: Updated FreeType to release 2.5.3 of March 6, 2014. Provides security fixes for CVE-2014-2240.
> - jpeg: Update to libjpeg 9a of 19-Jan-2014.
> - png: Update to Libpng 1.6.10 - March 6, 2014.

2014-03-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/nt_base.c (NTResourceToBlob): According to Microsoft Report article 193678 (http://support.microsoft.com/kb/193678), FreeResource() is not needed in WIN32 and performs no useful function. Remove use of it. Also remove use of UnlockResource() which is similarly unuseful for WIN32.
> - configure.ac (MAGICK_LIBRARY_REVISION): Test for Windows _aligned_malloc() is not reliable. Use Windows CRT version to decide if it is available.

2014-03-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/studio.h: Make sure that Windows _aligned_malloc() is not used under MinGW unless the CRT version allows it.

2014-02-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/pixel_cache.c (InterpolateViewColor): Applied patch by Troy Patteson plus fixes to ignore opacity channel if image matte is false. Replaces most of the code rewritten on 2014-02-16 and which produced a faint darkened border. The results look stellar now.

2014-02-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/shear.c: Applied patch by Troy Patteson to improve non-integral rotation by around 40% by minimizing added image borders. This may cause small differences in results for some images.
> - reference/filter/Rotate10.miff: Update rotate 10 degrees reference image so that PerlMagick test passes.
> - magick/shear.c: Applied patch by Troy Patteson to fix SourceForge issue #260 "Rotation exhibits clipping/shearing errors for short wide images at some angles".

2014-02-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - doc/options.imdoc: Fix documentation to note that 'unspecified alpha' is the GraphicsMagick default when writing TIFF rather than 'associated alpha'. Much thanks to Mats Peterson for alerting us of this error.

2014-02-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/pixel_cache.c (InterpolateViewColor): Added a hack so that affine transformations and displace composite do not have background colored fringing on the transferred image edges when the background is completely transparent. Fringing problem was caused by one or more of the line ends being a transparent pixel outside of the bounds of the original image content. May not be the final solution.

2014-02-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/semaphore.c (AcquireSemaphoreInfo): Document that this function was deprecated. (LiberateSemaphoreInfo): Document that this function was deprecated.

2014-02-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/psd.c (RegisterPSDImage): Set PSD to UnstableCoderClass since its implementation is currently rather marginal. It may even be that this coder deserves to be marked with the new BrokenCoderClass. We are still looking for a volunteer to iron out the wrinkles in the PSD reader.
> - magick/magick.h (CoderClass): Added BrokenCoderClass to mark coders which often malfunction or are not very useful in their current condition. Sometimes there is still hope that problems will be resolved and so the source file is not outright deleted. This setting allows us to mark and use coders which might malfunction by defining MAGICK_CODER_STABILITY=BROKEN in the environment while not causing danger for normal use.

2014-02-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - wand/magick_wand.c: Documentation improvements for MagickSetInterlaceScheme() and MagickSetImageInterlaceScheme(). Resolves SourceForge bug #262 "setImageInterlaceScheme doesn't make image progressive".

2014-02-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/{ps.c, ps2.c, ps3.c, pdf.c}: Only use resolution from image or -density if units was properly specified. Without units, resolution is worthless.
> - coders/ps3.c (WritePS3Image): Use image resolution similar to PDF changes.
> - coders/ps2.c (WritePS2Image): Use image resolution similar to PDF changes.
> - coders/ps.c (WritePSImage): Use image resolution similar to PDF changes.
> - coders/pdf.c (WritePDFImage): Use resolution from image if it appears to be valid. Resolves SourceForge issue #261 "PNG Pixel Density Not Preserved Converting to PDF".
> - magick/enum_strings.c (StringToResolutionType): New function to convert ResolutionType to C string. (ResolutionTypeToString): New function to convert from C string to ResolutionType.

2014-02-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - wand/magick_wand.c (MagickGetImageGeometry): New function to get the image geometry string. This function and the three others in this change set are contributed by Sara Shafaei. (MagickGetImageMatte): New function to read the image matte (opacity) channel enable flag. (MagickSetImageGeometry): New function to set the image geometry string. (MagickSetImageMatte): New function to set the image matte (opacity) channel enable flag.

2014-01-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - wand/magick_wand.c (MagickDrawImage): Remove development debug fprintf which causes each drawing primitive to be printed to stderr.

2014-01-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/pnm.c (ReadPNMImage): Fix scaling of alpha in sub-ranged pixels. Addresses SourceForge issue #237 "Incorrect MAXVAL scaling when reading PAM images", which was not fully fixed in by the previous attempt.

2014-01-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/tsd.c: Implement TSD for "pure" OpenMP mode without relying on POSIX or WIN32 TSD APIs.
> - magick/semaphore.c: Implement OpenMP-based locking so that code can compile in a "pure" OpenMP mode without relying on POSIX or WIN32 locking APIs.
> - configure.ac: --without-threads no longer disables use of OpenMP. Use the already existing option --disable-openmp to disable OpenMP.

2014-01-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/common.h: Support use of clang/llvm __attribute__ and __builtin extensions similar to the existing support for GCC.

2014-01-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Magick++/lib/Image.cpp (thumbnail): New method for fast image resizing, particularly to make thumbnails.
> - coders/gif.c: Log when Netscape loop exension is read and written.
> - coders/png.c (WriteOnePNGImage): In optimize mode, disable matte channel immediately if there are no non-opaque pixels. Also added some useful logging. Resolves SourceForge issue #252 "convert an 8bit PNG result in a corrupted image ".
> - wand/magick_wand.c (MagickSetImageGravity): New Wand method to set image gravity. (MagickGetImageGravity): New wand method to get image gravity.

2014-01-02 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>

> - coders/png.c (ReadOnePNGImage): Use libpng function png_set_strip_16_to_8() when scaling 16-bit input PNG down to 8-bit in a Q8 build. The png_set_scale_16_to_8() function is more accurate, but the slight difference causes reference tests to fail and causes unexpected difference between the behavior of PNG and other formats. If png_set_strip_16_to_8() is not supported in libpng, then we use png_set_scale_16_to_8() if that is available.
