Special Issues:
Due to GCC bug 53967, several key agorithms (e.g. convolution) may execute much faster (e.g. 2-3X) for x86-64 and/or when SSE is enabled for floating point math (-mfpmath=sse) if the GCC option -frename-registers is used. Default 32-bit builds do not experience the problem since they use '387 math. It is not clear in what version of GCC this problem started but it was not noticed by the developers until the GCC 4.6 timeframe. Other compilers do not suffer from this bug. Please lobby the GCC project to fix this embarrassing performance bug.
Bug fixes:
Compilation: No longer undefine __attribute__ since this may be used by system or compiler headers and cause problems.
BMP: Alpha channel from BMP3 format was inverted.
PNG: Fix round-trip repeatability issue (due to rounding algorithm) with modern versions of libpng. Prefer the less accurate method which does not alter the image.
PNG: Fix some memory leaks in error-handling paths.
PNM: Scaling of alpha in sub-ranged pixels is fixed.
Wand API: Removed development debug fprintf which causes each drawing primitive to be printed to stderr.
PS, PS2, PS3, PDF: Only use resolution from image or -density if units was properly specified. Without units, resolution is worthless.
PS, PS2, PS3, PDF: Use resolution from image if it appears to be valid.
WebP: Fix inverted return status which caused failure to be reported instead of success.
Rotation clipping/shearing errors for short wide images at some angles is fixed.
-geometry: 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.
-geometry: Support '>' and '<' qualifiers with '@' qualifier to specify if image should be resized if larger or lesser than given area specification.
New Features:
Wand API: MagickSetImageGravity() - New function to set image gravity.
Wand API: MagickGetImageGravity() - New function to get image gravity.
Wand API: MagickSetImageMatte() - New function to set the image matte channel enable flag.
Wand API: MagickGetImageMatte() - New function to read the image matte channel enable flag.
Wand API: MagickSetImageGeometry() - New function to set the image geometry string.
Wand API: MagickGetImageGeometry() - New function to get the image geometry string.
Wand API: MagickOperatorImageChannel() - New function to apply an operator to an image channel.
Magick++ API: New Image::thumbnail() method for fast image resizing, particularly to make thumbnails.
Core C API: Added SetLogMethod() to allow an application/library to specify a function to be called for logging.
Clang/LLVM: Provide support for clang/llvm attribute and builtin specifiers similar to that provided for GCC.
OpenMP: OpenMP native locking and thread specific data is supported via a configuration option (is not the default). This offers a "pure" OpenMP compilation mode. No real value for this compilation mode has been observed yet but it seems worthy to support.
Coders: Added BrokenCoderClass to mark coders which often malfunction or are not very useful in their current condition.
Composition: Added HardLight composition operator, which is now used by PSD and XCF formats, and available via command line, Magick++ API, PerlMagick API, and Wand API.
Composition: Added ScreenCompositePixels composition operator.
Composition: Added missing Photoshop separable compositing operations, Overlay, Exclusion, ColorBurn, ColorDodge, SoftLight, LinearBurn, LinearDodge, LinearLight, VividLight, PinLight, HardMix.
+set: Command line utilities now support +set to remove an existing image attribute.
-format: Support additional format specifiers 'g', 'A', 'C', 'D', 'G', 'H', 'M', 'O', 'P', 'Q', 'T', 'U', 'W', 'X', and '@', similar to the major brand.
-operator: New quantum operators ThresholdBlackNegateQuantumOp and ThresholdWhiteNegateQuantumOp These correspond to -operator "Threshold-Black-Negate" and "Threshold-White-Negate".
TIFF: Now support setting the TIFF "Software" tag for users who do not want to admit to using GraphicsMagick.
WebP: All of the WebP encoder encoder options are now supported by -define arguments.
Feature improvements:
Pixel interpolation quality is greatly improved, with minimal impact on performance. Pixel interpolation now also works well given an alpha channel.
WebP: WebP support is now prepared to compile with most WebP library versions and supports all features except for those pertaining to "RIFF" container support.
Performance Improvements:
Non-integral image rotation performance has been improved by about 40%, with lower memory usage as well.
GradientImage: Update image is_grayscale and is_monochrome flags based on gradient color properties.
Windows Delegate Updates/Additions:
PNG: Libpng 1.6.12 - June 12, 2014.
JPEG: libjpeg 9a of January 19, 2014.
FreeType: FreeType 2.5.3 of March 6, 2014.
WebP: webp 0.4.0 of January 20, 2013.
zlib: zlib 1.2.8 of April 28, 2013.
Build Changes:
--without-threads no longer disables use of OpenMP. Use the already existing option --disable-openmp to disable OpenMP.
Makefiles: Include paths are now exceedingly pedantic to make sure that only the required directories are included.
VisualMagick configure: Improve configure program so that it is possible to select QuantumDepth, OpenMP, and 64-bit build via configure dialog boxes as well as options on the command line. Also automatically detects and deals with similarly named files in subdirectories so that WebP support can now build successfully.
Behavior Changes:
MultiplyCompositePixels: Multiply composition now uses SVG interpretation of how alpha should be handled. No longer does a simple multiply of alpha channel.
Composition: The Difference, Darken, Lighten, and HardLight composition operators were modified to support alpha in their computations.
PNG: Using -optimize no longer triggers palette and depth optimizations since their implementations have been problematic.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
Security Fixes:
EPT: Fix crash observed when Ghostscript fails to produce useful output. This was particularly noticeable when Ghostscript was not installed. This crash could be used to cause denial of service.
PNG: With libpng 1.6.X, avoid a crash while copying a PNG with a "known incorrect ICC profile". This crash could be used to cause denial of service.
Bug fixes:
Build: Fix cross-compilation for MinGW64 on Linux build machine.
Build: configure FreeType test no longer insists that <freetype/freetype.h> can be included.
CMS profile: Only delete the CMS transform if it is non-null. Fixes assersion observed when lcms returned a null profile and GraphicsMagick attempted to deallocate it.
Drawing: Improve error handling logic so that drawing returns quickly on pixel access errors rather than plowing on ahead. This avoids problems with SVGs which take seemingly forever to render.
Drawing via C/C++ APIs: BevelJoin no longer causes a MVG parsing error.
EPT: Fix crash observed when Ghostscript fails to produce useful output. This was particularly noticeable when Ghostscript was not installed.
OpenMP: Revert use of omp_set_dynamic() since it caused performance issues when using GCC's GOMP implementation and the number of threads to use is specified.
EXIF profile: Support the SubjectArea EXIF tag.
MIFF writer: PseudoClass format was written incorrectly for depth greater than 8.
MIFF writer: RLE compressed format used inverted alpha from the other subformats and contrary to the MIFF specification.
MIFF reader: Fixes Fixes to be able to read MIFF written by ImageMagick 6.X, including DirectClass grayscale images (except for RLE compressed).
Mosaic: Fixed unsigned underflow problem with -mosaic when page offset is negative and exceeds image width or height, resulting in assertions, out of memory errors, or pixel cache limit errors.
PDF: Consistently initialize Image page width and height to image width and height. While general to all of GraphicsMagick, this change is to assure that the PDF writer computes page dimensioning consistently. PDF page dimensioning was wrong if the image had been resized with -geometry "100%".
PAM: Fix MAXVAL scaling when reading PAM images. PAM was only working correctly for images with 256 or 64k levels.
PNM: PGM "P2" format writer wrote bad output for 8-bit depth.
PNG: With libpng 1.6.X, avoid a crash while copying a PNG with a "known incorrect ICC profile".
PNG: Q8 GM build now correctly reads 16-bit PNG files.
TIFF writer: Try to avoid writing more than 32k strips per image by increasing rows-per-strip since some programs fail to read images with more than 32k strips per image.
TIM reader: PSX TIM reports 8-bit depth (rather than 16).
TTF font rendering: Improve FreeType rendering error logic so that rendering returns immediately on pixel access errors rather than plowing on ahead.
TTF font rendering: Support rendering UTF-8 up to 21-bit code points. Was only supporting 16-bit code points.
Wand API: DrawSetStrokeDashArray() / DrawGetStrokeDashArray(), fix failure to work properly due to this code path never being tested.
Windows Ghostscript: 64-bit GraphicsMagick no longer requires both 32-bit and 64-bit builds of Ghostscript to be installed in order to read Postscript and PDF formats.
XPM reader: Reported depth now depends on the colormap rather than always claiming to be 16-bit.
New Features:
JPEG: Add support for writing 'XMP' profile.
PNM: As a simple non-standard extension to the standard PNM and PAM formats, support writing and reading 32-bit sample depth. Writing such files is only supported by the Q32 build although they may be read by any build.
WebP: Now supports reading and writing Google's WebP format. This feature is not currently supported by the Windows Visual Studio build.
to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.
Suggested by tron in PR 47882
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
Security Fixes:
* PNG: Fix for CVE-2012-3438. The Magick_png_malloc function in
coders/png.c in GraphicsMagick 6.7.8-6 does not use the proper
variable type for the allocation size, which might allow remote
attackers to cause a denial of service (crash) via a crafted PNG
file that triggers incorrect memory allocation.
* Automake (derived): Fix for CVE-2012-3386: The "make distcheck"
rule in GNU Automake before 1.11.6 and 1.12.x before 1.12.2 grants
world-writable permissions to the extraction directory, which
introduces a race condition that allows local users to execute
arbitrary code via unspecified vectors.
Bug fixes:
* PNG: Reading sub-8-bit palette images is fixed (images looked
stretched).
* SVG: Fixed bug which allowed MVG and SVG files with long vector
paths to crash the software.
* SVG: Ignore XML headers rather than rendering them as text.
* MVG/SVG/WMF/-draw: It is now possible to draw a plain ','
character.
* WMF: Fixed a bug which caused wrong centered-text placement.
* import: Return status was inverted.
* configure: Don't force that liblzma is used just because libtiff
is used.
New Features:
* The configure script now supports a --enable-quantum-library-names
option 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).
* JNX: Support is added for reading the Garmin proprietary Image
Format.
* BMP: Support an alpha channel in uncompressed 32-bit BMP.
Feature improvements:
* -lat: The adaptive threshold algorithm is replaced with a new
algorithm which scales linearly (rather than quadratically) with
area size.
* Tests: Test suite is re-written to use TAP-based tests.
* GIF: Reader tries to be better at detecting and reporting
failures.
Performance Improvements:
* -lat: Adaptive threshold is much faster with large area sizes.
Windows Delegate Updates:
* Dcraw 9.16 is now included in the build (with JPEG and JPEG2000
support).
* Libxml2 is updated to the 2.9.0 release.
* Libtiff is updated to the 4.0.3 release.
* Lcms2 is updated to the 2.4 release.
* Libpng is updated to the 1.5.13 release.
Behavior Changes:
* Loading modules is only supported for the modules build.
Previously any build using shared libraries could load modules.
* Bundled libltdl is now configured as 'installable' rather than
'convenience'.
* -enhance: Only filter based on color channels (ignore opacity).
* BrowseDelegate: Web browser (for viewing help information) now
defaults to 'xdg-open', but if it is not found, then configure
will search for firefox, google-chrome, mozilla (in that order).
Bump PKGREVISION.
It introduce bump PKGREVISION of p5-GraphicsMagick.
While here,
* move distinfo and patches location to Makefile.common.
* let to exactly linked against installed GraphicsMagick.

-------------------------------------
This is an objected-oriented Perl interface to GraphicsMagick, a fork of
ImageMagick. It provides an interface similar to that PerlMagick provides
to ImageMagick, but wit a different class name.
Use the module to read, manipulate, or write an image or image sequence from
within a Perl script. This makes it suitable for Web CGI scripts.
