GraphicsMagick 1.1.3 released

GraphicsMagick 1.1.3 is now available.  This is an important release 
since it incorporates a vital security fix for the PNG format, enables 
LZW compression for GIF and TIFF, and fixes a number of bugs. Please 
see "http://www.GraphicsMagick.org/" for how to download 
GraphicsMagick.

The following are the significant enhancements in the 1.1.X series 
over and above GraphicsMagick 1.0:

Significant changes associated with GraphicsMagick 1.1.3 (released August 7, 2004)

   Bugs fixed:
     * PNG fixes for CERT security alert TA04-217A described at
     "http://www.us-cert.gov/cas/techalerts/TA04-217A.html".
     * Take resolution units into consideration when resampling an image.
     * If image units are changed, rescale existing image resolution values
     to match.
     * Fixed problems with reading and writing large PCX files.
     * Fixed crash in Wand library MagickSetPassphrase().
     * When a Wand library function is used for which a backing
     implementation does not yet exist, report a "not implemented" error
     rather than just returning an error status.
     * Fixed a problem when reading some BMP v4 files.
     * DESTDIR install now works properly with PERL 5.8.1 and later.

   Improvements:
     * Support reading RGB/CMYK scanline oriented TIFF images with arbitrary
     depth.
     * LZW support for GIF and TIFF is enabled by default.
     * Incorporated lcms 1.13 for more speed, and bug-fixes.
     * The configure script now looks for mozilla (or firebird) when looking
     for a web browser.  Netscape is used if mozilla or firebird are not present.

Significant changes associated with GraphicsMagick 1.1.2 (released June 6, 2004)

   Bugs fixed:
     * The source RPM package was not installing the *-config scripts with
     execute permissions.
     * Under Windows, the Ghostscript fonts were not being found for
     Ghostscript 8.X.X installs.
     * For the "moby" (shared, non-module) build, loading all modules was
     reporting an error while running the test suite due to not locating the
     LOGO module.  The "moby" build was not really able to load external
     modules at all.
     * Fixed building under the current MinGW development environment.
     * Fixed usage message for `mogrify' (was missing -operator).
     * Fixes for SetImageOpacity().

   Improvements:
     * Significant performance improvments (4X) in DispatchImage() and
     ConstituteImage() for byte-sized input/output and the patterns BGR,
     BGRO, BGRP, RGB, RGBO, and I.
     * The module loader now properly considers the module loading path in
     all cases.  This means that modules may be located in multiple directories
     and the user may supply his own modules in some other location.  Module
     loading now works as intended for the "moby" build even though the
     standard modules are included in the GraphicsMagick shared library or DLL.
     * Under Windows, initialization time should be somewhat improved while
     loading the type.mgk (font description) file.

Significant changes associated with GraphicsMagick 1.1.1 (released May 2, 2004))

   Bug fixes:
     * Fixed a strtod/scanf bug with parsing some arguments starting with
     "0x" under Linux.
     * Fixed a double-free bug in the display program.
     * GraphicsMagick now successfully builds and passes all tests under
     Digital Unix 5.1, using the vendor compiler.
     * Ghostscript sometimes displays an error message and fails, yet it
     returns a success error code to GraphicsMagick. Verify that
     Ghostscript has updated the output file before attempting to use it.
     * Eliminated an out of bounds array access in HuffmanEncode2Image().
     * Fixed a configure script syntax error when testing for trio.

   Utilities enhancements:
     * If gm is executed under a traditional alternate name (e.g.
     convert), it will invoke the appropriate sub-command. This allows use
     of hard links, symbolic links, or just copying 'gm' to the desired
     sub-command name in order to achieve 100% ImageMagick 5.5.2 utility
     compatibility.
     * Provide the --enable-magick-compat option when configuring to install
     ImageMagick utilities compatibility links.

Significant changes associated with GraphicsMagick 1.1 (released April 4, 2004)

   Bug fixes:
     * Semaphore fix which is necessary for proper multi-threaded operation.
     * Configure script fix to ensure that -lfpx is not supplied to the C
     compiler during subsequent tests since this fails on some systems.
     * Fix for East and West gravity computations.
     * System error reports (errno) associated with an exception are now
     correctly obtained from the context existing when the exception was
     thrown rather than the context of the reporting function.
     * JNG encoder fix. Files were being written with incorrect
     alpha_sample_value in the header. These can be repaired by reading
     them into GM 1.1 and rewriting them.
     * XPM fix to module registration.
     * PSD fix for index calculation when QuantumDepth>8.
     * Validate that geometry specifications only include allowed
     characters.
     * SGI fix to save compression type while writing.
     * EXIF attributes were not being retrieved when requested.
     * Fix for bug when reading an image via a user-provided file
     descriptor.
     * The reported image magick string is now always that of the original
     input file (it was sometimes being reported as the format produced by
     an intermediate delegate program).
     * Fixes to color profiling of CMYK images.
     * Memory leak fixed in DrawClipPath().
     * Arc drawing is fixed.
     * Command-line parsing bug under Linux due to Linux's sscanfs
     inability to parse strings like "0x1" as "%fx%f" is fixed.
     * Scaling of 5 and 6-bit colors was slightly incorrect in BMP, AVI,
     DIB, and TIM datastreams.
     * GM utility now reports an error rather than silently returning if
     an unsupported sub-command is provided.

   Performance improvements:
     * Texture tiling is now 7X faster.
     * Color profile processing speed improvements for colormapped images.

   Utilities enhancements:
     * For Unix, 'gm version' now includes a dump of the configure and
     build parameters.
     * Logging of thrown exceptions is now supported. Use '-debug
     exception'. This is useful to learn when and where errors are
     reported.
     * The -define option is added in order to support supplying
     additional options to coders without needing to add additional
     command line options or structure members.
     * The output of 'gm identify -verbose' now provides a nice dump
     of EXIF data.
     * The -sampling-factor option now accepts as many HxV pairs as
     there are JPEG components.  Omitted ones default to 1x1.
     * The convert and montage commands now support an -operator command to
     perform arithmetic and bitwise operations on specified image channels.

   Coder additions/improvments
     * The META coder supports wide characters for the IPTC and 8BIM
     formats.
     * The XTRN coder now supports wide characters.
     * An "IMAGE" coder is provided which provides access to a large
     number of images (derived from XFig) suitable for use as patterns,
     or as test images.
     * The "PATTERN" coder now returns an image pattern tiled to size
     (equivalent results to TILE:IMAGE:pattern). This is for ImageMagick
     compatibility.
     * The CINEON coder now supports reading and writing images in CINEON
     "CIN" linear gray and RGB formats. The read support is still very
     weak, but it works for common images.
     * The JPEG coder now estimates the original JPEG quality and sampling
     factors and will reuse these options when writing JPEG if the image
     is of the same type and the option "-define JPEG:preserve-settings"
     is supplied.
     * The JPEG-2000 coder now supports all Jasper library arguments using
     command line syntax similar to '-define jp2:rate=0.5'.
     * Reading and writting compressed SVG (SVGZ) is now supported.
     * The TXT coder now observes depth when writing.
     * The TIFF coder now outputs colormapped images with 1, 2, 4, and 8
     bits per sample in order to provide much smaller file sizes for
     images with very few colors.
     * Many TIFF coder enhancements. Now reads colormapped and grayscale
     images at arbitrary (even odd) bits-per-sample sizes. Now properly
     supports an opacity channel (at any bits-per-sample value) for
     grayscale images. Bilevel grayscale images are treated similar to any
     other grayscale image unless CCITT FAX3/FAX4 compression is
     requested. Now allows the user to specify an arbitrary
     bits-per-sample value for grayscale images (even odd values) using
     "-define tiff:bits-per-sample=value". Now automatically stores the
     image as TrueColor RGB pixels if the image compression is set to JPEG.
     TIFF files are now written in using the TIFF library's default endian
     order rather than always big endian.
     * The WPG coder now renders embedded WMFs.
     * The PS3 coder is completely re-written to work much better and
     support more features (see ChangeLog).

   Code structure enhancements:
     * Error handling has been improved and validated through testing.
     Some errors were being lost, unnecessarily ignored, or reported as
     something else entirely.
     * The number of error text messages to be maintained has been reduced
     by consolidating similar messages.
     * The memory allocator functions have been replaced with similar
     macros in order to eliminate warnings with GCC 3.3, avoid
     accidentally casting away const, and allow memory debuggers to
     report memory allocations and frees against the correct functions.
     The previously-used functions remain in the library for the purpose
     of compatibility.
     * <magick/xwindow.h> no longer depends on magick_config.h defines.
     * The text string localization code has been replaced with a simpler
     version written by Bill Radcliffe.
     * Added key,value "map" APIs (somewhat similar to C++'s <map>) for
     internal use.

   API enhancements:
     * Incorporated John Cristy's Wand API's in a new GraphicsMagickWand
     library.
     * API definition is no longer dependent on types which vary in size
     (e.g. size_t) depending on large file compilation options.  This means
     that applications may now be compiled without any special large file
     options and still work properly with the library.
     * Thrown exceptions (ExceptionInfo structure) now include source
     file, source line, function name, and current system error number.
     * The GetMagickInfoArray() function is added to replace use of
     GetMagickInfo() for code which needs to access the coder list. This
     is necessary since invoking GetMagickInfo() may re-order the coder
     list, causing problems for code which traverses the list. Using
     GetMagickInfo() to access individual list elements is safe.
     * Added the CopyException function to support copying exception info
     from one structure to another.
     * Added the ReplaceImageInList function to replace an image in an
     image list.
     * Added the DrawPeekGraphicContext function to access the current
     DrawInfo structure in the drawing context stack. Use of this
     function is not recommended since it voilates proper programming
     practices. It is added to support the Wand API's.
     * GetImageDepth() now returns an integral value between 1 and
     QuantumDepth and is no longer limited to the values 8, 16, and 32.
     * SetImageDepth() supports setting the image modulus depth to any
     integral value between 1 and QuantumDepth. This effects the effective
     numeric precision, not the storage depth, since the quantum storage
     type is still a Quantum.
     * GetImageChannelDepth() supports retrieving the modulus depth for a
     specified channel.
     * SetImageChannelDepth() supports setting the modulus depth for a
     specified channel.
     * ProfileImage is updated to handle alpha channels and grayscale
     images.
     * Added GetImageProfile() to retrieve a CMS profile from an image.
     * Added SetImageProfile() to attach a CMS profile to an image without
     adjusting the image pixels.
     * Added DeleteImageProfile() to remove a CMS profile from an image.
     * ConstituteImage() and DispatchImage() now support 'T' (transparency),
     'O' (opacity), and 'P' (pad) options.
     * CompositeImage() now supports CopyCyanCompositeOp,
     CopyMagentaCompositeOp, CopyYellowCompositeOp, and
     CopyBlackCompositeOp, composition operators.
     * GetColorHistogram() obtains a color histogram for the image.
     * QuantumOperatorImage() and QuantumOperatorRegionImage() support
     arithmetic and bitwise operations on specified image channels.
     * The semaphore.h header is no longer installed or included in the
     API headers since these functions are private interfaces.
     * Configure using --enable-symbol-prefix or define
     PREFIX_MAGICK_SYMBOLS to use the C preprocessor to prefix all library
     symbols with "Gm". This prevents library symbol conflicts with other
     libraries.

   PerlMagick fixes:
     * Adjusted a number of function option names so that they match the
     documentation.
     * Memory leak fixed.
     * Reading files (e.g. GIF) via a file descriptor is fixed.

   Build improvements:

     * The TRIO library may be used to provide a replacement for vsnprintf
     if the C library doesn't provide it.  This improves security on old
     systems.
     * Configure only configures for C & C++ languages.
     * Configure now does a better job of figuring out how to build a
     thread-safe library across multiple operating systems.
     * Configure incorporates a new mmap() test which tests the
     functionality which is needed so that mmap() is not unnecessarily
     rejected on a number of systems. This improves performance for large
     files on those systems.
     * Configure/build fixes for IBM's AIX operating system.

   Windows-specific improvements:
     * The static install package now uses the "uninstalled"
     configuration so that it does not depend on the Windows registry in
     order to run. This allows files from the static install package to
     be copied to another computer without running an installer.
     * The executable search path is extended at run-time to include the
     directory where the CORE DLLs reside in order to ensure that they
     are found.
     * Adding the -t option to VisualMagick configure enables building
     all of the coders into one library in order to save build time and
     simplify linkage.
     * The XTRN coder now supports wide characters.
     * LCMS library updated to version 1.10.
     * GMDisplay displays a checkerboard pattern behind transparent images.
     * Support is provided for issuing log messages to the Windows standard
     logging system.
     * Project files are now provided for use with Borland C++ Builder 6.0.
     * Updated LCMS version to 1.12.
     * Updated FreeType version to 2.1.5.
     * Updated JBIG-KIT to version 1.5.
     * Updated libpng to version 1.2.5.
     * Updated libwmf to version 0.2.8.2.
     * Updates zlib to version 1.2.1.
     * ActivePerl 5.8.1 Build 807 now supported.
     * GraphicsMagick now compiles using Visual Studio .NET 2003.
