Log Message:
Update GraphicsMagick to 1.3.8.

1.3.8 (January 21, 2010)
========================

Security Fixes:

   * Fix for CVE-2009-1882 "Integer overflow in the XMakeImage
     function".

   * Fix lockup due to hanging in loop while parsing malformed
     sub-image specification (SourceForge issue 2886560).

   * Libltdl: Updated libtool to 2.2.6b in order to fix security issue.
     Resolves CVE-2009-3736 as it pertains to GraphicsMagick.

Bug fixes:

   * -convolve, -recolor: Validate that user-provided matrix is square
     when parsing -convolve and -recolor commands in order to avoid a
     core dump.

   * CALS: Reading images taller than the image width resulted in a
     failure.

   * ConstituteImage(), DispatchImage(): 'A' and 'T' should indicate
     transparency and 'O' should indicate opacity.  Behavior was
     inconsistent.  In some cases 'O' meant transparency while in other
     cases it meant opacity. Also, in a few cases, matte was not
     getting enabled in the image as it should.

   * DCRAW: Module name was not registered so modules based builds were
     not supporting formats provided via 'dcraw'.

   * GetOptimalKernelWidth1D(), GetOptimalKernelWidth2D(): In the Q32
     build, convolution kernel size was estimated incorrectly for large
     sigmas on 32-bit systems due to arithmetic overflow.  This could
     cause wrong results for -convolve, -blur, -sharpen, and other
     algorithms which use these functions.

   * Image Size: Fixed the ability to pass the image size via the
     filename specification like "myfile.jpg[640x480]" rather than
     needing to use -size.

   * IPTC: Blob data needed to be padded to an even size.  Size is now
     correctly reported.

   * IPTC: Returned IPTC string values were one character too short.

   * Large Files: Large pixel cache files were not working under GNU
     Linux.

   * JP2: Fixed some value scaling problems.

   * JP2: Fix possible crash at exit when Jasper is used by a modules
     build.

   * MPC: is_monochrome and is_grayscale flags were not managed
     properly for the MPC coder.

   * PCL: Page was not always being ejected.

   * PNG: The png8 encoder would fail when trying to write a 1-color
     image.

   * PSD: PSD parser was confused by 0x0 pixel layers, resulting in
     image data corruption of all following layers.

   * -rotate, -shear: Some internally-reported errors were potentially
     being lost.

   * Subrange/stdin: Commands now support reading an image from stdin
     in conjunction with a subrange specification (e.g. "-[1]").

   * Magick++ STL ShadeImage: Implementation was completely botched.

New Features:

   * CALS Type 1 files may now be written (Work contributed by John
     Sergeant).  CALS support is dependent on the TIFF library.

   * GROUP4RAW encoder supports reading/writing RAW Group4 data.

   * JP2: JPEG 2000 may now be written in arbitrary bit depths ranging
     from 2 to 16 rather than just 8 or 16.

   * JPEG: IJG JPEG library version 7 is now supported.

   * JPEG: Added jpeg:block-smoothing and jpeg:fancy-upsampling defines
     to control these JPEG library options.

   * JPEG: Detect and apply colorspaces appropriately for ITU FAX JPEG.

   * Resource Limits: There is now a "threads" resource limit which
     allows specifying the number of OpenMP threads which may be used,
     similar to the OMP_NUM_THREADS environment variable.

   * TIFF: Allow CIELAB TIFF to be read.

   * MagickGetImageAttribute()/MagickSetImageAttribute(): New Wand
     methods to support getting and setting an image attribute.
     Contributed by Mikko Koppanen.

   * ClonePixelWand(): New Wand method to deep-copy an existing pixel
     wand.

   * ClonePixelWands(): New Wand method to deep-copy an array of
     existing pixel wands.

   * MagickCdlImage(): New Wand method to apply the ASC CDL to an
     image.

   * MagickGetImageBoundingBox(): New Wand method to return the crop
     bounding box required to remove any solid-color border from the
     image.

   * MagickGetImageFuzz(), MagickSetImageFuzz(): New Wand methods to
     get and set the color comparison fuzz factor.

   * MagickHaldClutImage(): New Wand method to apply a Hald CLUT to an
     image.

   * MagickSetResolution(): New Wand method to set the wand resolution.

   * MagickSetResolutionUnits(): New Wand method to set the wand
     resolution units.

   * Magick++: Allow Magick++ library to built as a DLL under MinGW and
     Cygwin.  This requires a modern GCC in order for C++ exceptions to
     work.

Feature improvements:

   * Cygwin: Cygwin 1.7 is now supported.

   * JPEG compression settings are preserved (if possible) when
     inserting JPEG blobs into formats which use JPEG.

   * PDF: If the original file used JPEG compression, then use JPEG
     compression with original settings (if possible).

   * TIFF: Update Windows build to use libtiff 3.9.2.

   * X11 Display: Apply a checkerboard pattern underneath transparent
     images which use more than simple binary transparency.

Performance Improvements:

   * Gamma: Performance is improved for Q8 and Q16 builds.  Also
     preserve full precision in Q32 build.

   * String data is dealt with a bit more efficiently (fewer
     allocations, less memory, and less CPU).

Behavior Changes:

   * InitializeMagick() MUST be invoked prior to using any Magick API
     function.  Failure to do so will likely lead to an immediate
     application crash.  This is due to initialization and runtime
     changes intended to improve thread safety and efficiency.
     Previously it was only strongly recommended to invoke
     InitializeMagick().

   * ConstituteImage(), DispatchImage(): 'A' and 'T' should indicate
     transparency and 'O' should indicate opacity.  Behavior was
     inconsistent.  In some cases 'O' meant transparency while in other
     cases it meant opacity. Also, in a few cases, matte was not
     getting enabled in the image as it should.

   * colors.mgk: Is now empty to default and is optional.  Previous
     content is now compiled into the library in an efficient way, but
     existing values may be modified, or new values added by adding
     entries to color.mgk.

   * DisableSlowOpenMP is now the default.  Use --enable-openmp-slow to
     enable OpenMP for algorithms which sometimes run slower rather
     than faster.

   * magic.mgk: This configuration file is no longer used since this
     data is now compiled into the library in an efficient way.

   * modules.mgk: Is now empty to default and is optional.  Previous
     content is now compiled into the library in an efficient way, but
     existing values may be modified, or new values added by adding
     entries to modules.mgk.

   * Third party executables not included in the Visual Studio build
     are no longer bundled in the GraphicsMagick installer.  This means
     that hp2xx.exe, mpeg2dec.exe, and mpeg2enc.exe are no longer
     distributed.
