GraphicsMagick 1.3.7 Released

GraphicsMagick 1.3.7 is now available.  This release is both a feature 
and bug-fix release.  The release was hastened due to a corruption bug 
discovered with embedded profiles in JPEG files.  Regardless, there 
are many bug fixes, and many new/improved features as well.

The following are the improvements in GraphicsMagick since the 
previous 1.3.6 release:

Security Fixes:

   * PCX: Detect improper rows, columns, or depth.  Fixes CVE-2008-1097
     "Memory corruption in ImageMagick's PCX coder".

   * DrawDashPolygon: Avoid a crash which sometimes occured with tiny
     polygons.

Bug fixes:

   * JPEG: Profile chunks need to be concatentated in order to build
     the whole profile.  This was not working so embedded profiles
     larger than 32K or maybe 64K were being corrupted.  This bug was
     introduced in GraphicsMagick 1.2.

   * Meta: Fix memory leaks.

   * Meta: Work better with with IPTC record 2 blocks and deal better
     with IPTC embedded in an 8BIM profile.  Fixes by John Sergeant.

   * MPC: Fix crash when reading MPC and the input image is modified.

   * PNG: Ensure that the opacity channel is properly initialized.

   * -profile: Lowercase arguments were sometimes not working as
     expected.

   * Topol: Topol reader actually works now and is included in test
     suite.

   * TIFF: Read and write JPEG-compressed grayscale TIFF correctly.

   * VisualMagick configure now works properly when output paths are
     specified.

   * WMF: Eliminate memory leaks.

New Features:

   * MagickWand: New method MagickSetCompressionQuality() to allow
     setting the compression quality.

   * MagickWand: New method CloneDrawingWand() to deep-copy a drawing
     wand.

   * MagickWand: New method DrawGetException() to retrieve information
     regarding the last drawing wand exception (if any).

   * MagickWand: New method DrawClearException() to clear a drawing wand
     exception.

   * Magick++: New Image method cdl() to apply the ASC CDL.

   * Magick++: New Image method colorMatrix() to apply a color matrix
     to the image channels.

   * Magick++: New Image method haldClut() to apply a color lookup
     table (Hald CLUT) to the image.

   * MSL/Conjure: Added a new 'profile' command which applies, adds, or
     removes one or more IPTC, ICC or generic profiles from a file.
     Work contributed by John Sergeant.

   * Added a 'time' subcommand to provide Unix-style 'time' output when
     a 'time' capability is missing, or the reporting format is
     inconsistent.  For example 'gm time convert ...'.

Feature improvements:

   * ColorMatrixImage(): Add opaque opacity channel when needed.

   * PDF & PS: Use '-type palette' prior to input file name to cause
     Ghostscript to return a dithered colormapped image.

   * PNG: Now compiles with libpng-1.4.0beta74 and later.

   * TIFF: Libtiff in Windows build is upgraded to 3.9.1.  This allows
     GraphicsMagick to read and write 16 and 24 bit float TIFF files.

   * Windows code to find Ghostscript is rewritten from scratch.

Performance Improvements:

   * Drawing of points, lines, and polygons (and complex shapes based
     on these) is now accelerated using OpenMP with excellent speed-up.

   * ICC color transforms now see linear speedup from OpenMP.

   * Rotate: For rotations of 90 or 270 degrees, tile sizes are
     selected more appropriately.

Behavior Changes:

   * No longer clear the exception structure at the start of
     ReadImage() and other similar functions since this sometimes masks
     errors.  The API user is expected to make sure that the exception
     structure is clean prior to invoking a function.

   * SVG: Writer is now disabled since it usually does not work properly.

Thanks,

Bob
