2008-12-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/OpenMP.rst: Add results for Window Vista 64-bit / AMD Phenom
        X4 9550.

        * VisualMagick/installer/inc/body.isx: Revert yesterday's change
        regarding the placement of config files.  Place the config files
        in a `config` subdirectory just as before.

2008-12-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * VisualMagick/installer/inc/body.isx: They say that when in Rome
        you should do as the Roman's do.  Based on this philosophy, all of
        the coder and filter DLLs are now installed to the same directory
        as the executables and DLLs which depend on them.  This eases
        operation under Windows Vista.

2008-12-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/blob.c: First pass at supporting large file access under
        Windows.

2008-12-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/resource.c (InitializeMagickResources): Improve resource
        estimation for Microsoft Windows systems with large memory.

        * magick/segment.c: Added some code to dump histograms with
        `-verbose -verbose`.

        * coders/tiff.c: Support reading/writing 16 and 24 bit float TIFF
        files.

        * magick/constitute.c (ExportViewPixelArea): Support exporting 16
        and 24 bit short floats.  Relies on code developed for
        GraphicsMagick by Richard Nolde.
        (ImportViewPixelArea): Support importing 16 and 24 bit short
        floats.  Relies on code developed for GraphicsMagick by Richard
        Nolde.

2008-12-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/operator.h (enum QuantumOperator): Added LogQuantumOp,
        MaxQuantumOp, MinQuantumOp, and PowQuantumOp enumerations as well
        as "Log", "Max", "Min", and "Pow" options to -operator.

2008-12-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MogrifyImage): The -write option was not
        implemented in a useful fashion and the +write option never worked
        at all.  Re-implement -write and eliminate +write from the
        documentation since +write is not needed.

2008-12-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (ReadTIFFImage, WriteTIFFImage) Support reading
        and writing 64-bit integer TIFF.

        values.

2008-12-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (ReadTIFFImage): Fix bug with reading one bit per
        sample RGB images.

2008-12-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/pixel_cache.c (OpenCache): Fix a code ordering problem
        which results in `identify` throwing an assertion for PseudoClass
        image files.  This bug was added in the 1.3.2 release.

        * coders/tiff.c (ReadTIFFImage): Fix bug with `ping` mode.

2008-12-07  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/fits.c: Proper signed to unsigned conversion for 64 bit LSB images.

2008-12-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/Makefile.am: When X11 is disabled, don't compile the
        X11-specific source modules.  Don't ever install any X11-related
        header files.

2008-12-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/segment.c (SegmentImage): Use `double` rather than 64-bit
        integer to accumulate totalized values.  Make the cluster summary
        report more concise.

2008-12-06  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/fits.c: Fix for 64 bit images.

2008-12-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/segment.c (SegmentImage): Cluster threshold is expressed
        as a percentage of total cluster pixels.  Optimize for larger
        images.

2008-12-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/segment.c (SegmentImage): Accelerate using OpenMP.

2008-11-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/utility.c (ExpandFilenames): Remove some arbitrary
        argument length limits.  Pass -convolve argument without any
        additional checking.  Verify that strings are not truncated during
        copy.
        (ListFiles): Be more memory efficient.

        * magick/fx.c (ConvolveImage): Fix formatting problem when logging
        the convolution kernel used.

        * magick/utility.c (TranslateTextEx): Support formatting huge
        comment text.

2008-11-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/fx.c (ConvolveImage): Don`t process opacity channel
        unless image has one.

        * magick/effect.c (MotionBlurImage): Use
        AcquireOnePixelByReference() rather than AcquireImagePixels() to
        retrieve one pixel.  This is much more efficient.
        (AdaptiveThresholdImage): Don`t process opacity channel unless
        image has one.
        (BlurImage): Don`t process opacity channel unless image has one.

2008-11-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/profile.c (ProfileImage): +profile now supports a simple
        exclusion syntax.  For example, to strip all of the profiles
        except for the ICM profile use +profile '!icm,*'.  The new syntax
        also allows multiple profile names to be listed at once.  The
        primary requirement is that all excluded profiles must be listed
        prior to those to be stripped.

2008-11-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/transform.c (RollImage): Remove image storage class
        alteration.
        (CompositeImageRegion): Ensure that the canvas image storage class
        is correct.

2008-11-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * config/delegates.mgk.in: Since we removed support for `spawn` a
        long time ago, and no longer execute using the Unix shell by
        default, we need to add an ampersand to the end of the two entries
        previously using `spawn` so that the display program does not hang
        when it invokes the external program.

        * utilities/Makefile.am (UTILITIES_TESTS): Add preview-based
        tests.

        * coders/preview.c (WritePreviewImage): Solarize requires a
        threshold argument.

        * coders/vid.c (WriteVIDImage): Eliminate memory leak.

        * magick/montage.c (MontageImages): Fix continued use of freed
        memory.

2008-11-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/omp_data_view.c (AccessThreadViewDataById): New function
        to allow retrieving data via the index it was registered with.

        * magick/enhance.c (BuildChannelHistograms): EnhanceImage() and
        NormalizeImage() now share one common function for generating the
        histogram.

        * magick/enhance.c (ModulateImage): Improve performance a bit.
        (ContrastImage): Improve performance a bit.
        (GammaImage): Improve performance a bit.

2008-11-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/authors.rst: List Mark Mitchell as an author.

        * utilities/tests/msl_composite.sh: Fix `rm -f` without a valid
        argument which annoyed NetBSD.

        * coders/fits.c: Impose a limit on the length of the row PDU.
        Make sure that GraphicsMagick version information does not
        overflow the length allowed by a row PDU.

2008-11-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/jpeg.c (WriteJPEGImage): Use DCT algorithm default from
        the library rather than the header file.

        * magick: Adjust OpenMP scheduling options based on observed
        behavior.

2008-11-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/shear.c (IntegralRotateImage): Added OpenMP acceleration
        for rotate by 90 and 270 degrees.

        * configure.ac: New --disable-openmp-slow configure for disabling
        use of OpenMP for algorithms which may run slower on operating
        systems with crummy thread libraries.  This still allows gaining
        the benefits from OpenMP for CPU hogs.  Verified to help with
        FreeBSD 7.0 and Apple OS-X Leopard.

        * magick/semaphore.c: Trimmed out the debug code in order to
        obtain a bit more performance.

2008-11-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/jpeg.c: Allow the user to specify the DCT method
        (jpeg:dct-method), or if huffman encoding should be enabled
        (jpeg:optimize-coding=true).  Default the DCT method to the
        libjpeg default rather than forcing it to JDCT_FLOAT since float
        is slower on some systems.

2008-11-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/jp2.c (BlobClose): Leak a little bit less memory when
        reading a JP2 file.

2008-11-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * wand/wandtest.c: Eliminate memory leak.

        * wand/drawing_wand.c (DestroyDrawingWand): Eliminate memory
        leaks.

        * coders/xwd.c (WriteXWDImage): Force colormapped images with more
        than 256 colors to DirectClass.

        * magick/enhance.c (ModulateImage): Improve progress message.

        * coders/msl.c: Eliminate memory leaks.

        * GraphicsMagick.spec.in: Apply RPM spec file fixes from Giacomo
        Tenaglia for Red Hat Linux 4.

2008-11-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/msl.c: Fix bug with attributes becoming appended to
        themselves.  Resolves SF issue 2255754. Reflowed code.

2008-11-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * version.sh: GraphicsMagick 1.3 released.
        Next release on head will be 1.4.

        * www/OpenMP.rst: Updated with latest measurement data.

        * www/benchmarks.rst: Updated with latest benchmark data.

        * coders/url.c (RegisterURLImage): Register HTTP and FTP URL
        support in the "unstable" category since these are capable of
        accessing the network and therefore represent a potential security
        issue.  Register the FILE URL support in the "stable" category
        since it is capable of incorporating local disk files, which may
        still represent a security security issue for server applications.
        Note that disabling these functions might cause some existing MSL,
        MVG and SVG scripts to stop working if they use external URLs.

2008-11-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/pnm.c (ReadPNMImage): Sequential multi-thread the PNM raw
        format readers. Can improve read performance quite substantially
        for large PBM and PGM files, and less so for PPM.  There is most
        benefit for systems with more I/O than one CPU core will support.
        Systems with slow I/O and a relatively fast CPU may see somewhat
        diminished read performance with more CPU consumption.  As such,
        this is effectively a verification that multi-threading the reader
        is possible, and may be of benefit to power-users.

        * magick/omp_data_view.c (AllocateThreadViewDataArray): New
        function to allocate a thread view data array.  Updated modules
        using similar code to use this function in order eliminate
        useless redundancy.

2008-11-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/pixel_cache.c: Incorporate OMP thread views into the
        pixel cache so usage is less invasive.  Update OMP-enhanced source
        modules to suit.
        (GetImagePixelsEx): New function similar to GetImagePixels()
        except that it reports exceptions to a user-provided structure.
        (SetImagePixelsEx): New function similar to SetImagePixels()
        except that it reports exceptions to a user-provided structure.
        (SyncImagePixelsEx): New function similar to SyncImagePixels()
        except that it reports exceptions to a user-provided structure.
        (AccessImmutableIndexes): New function to access read-only
        colormap indexes.
        (AccessMutableIndexes): New function to access writeable colormap
        indexes.
        (AccessMutablePixels): New function to access writeable pixels.
        (AccessDefaultCacheView): New function to access the default cache
        view.

2008-11-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (BenchmarkImageCommand): With no other
        arguments, the benchmark command now defaults to one iteration.

        * magick/effect.c (SpreadImage): Offsets array size is a prime
        number to help avoid beating.
        (SpreadImage): Ensure that spread loops are always terminal.

        * magick/utility.c (MagickRandReentrant): Fix bug where rand() was
        being continually re-seeded if rand_r() was not available.

2008-11-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * utilities/tests/msl_composite.sh: Replace SVG image generation
        with simpler approach which properly centers the text.  Use our
        own font so that tests will pass if the user does not have fonts
        installed.

        * magick/utility.c (GetMagickDimension): Extend to support parsing
        optional x and y offset values and use to fix parsing for
        -oil-paint and -unsharp when sscanf() is C'99 compliant.

2008-11-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/pixel_cache.h (AcquireOneCacheViewPixel): Pass pixel to
        update by reference.
        (AcquireOnePixelByReference): New private inline method which
        passes pixel to update by reference.

        * magick/omp_thread_view.h (AcquireOneThreadViewPixel): Pass pixel
        to update by reference.

        * magick/alpha_composite.h (BlendCompositePixel): Replace
        BlendComposite with BlendCompositePixel, which passes the
        composite pixel by reference.
        (AlphaCompositePixel): Replace AlphaComposite with
        AlphaCompositePixel, which passes the composite pixel by
        reference.
        (AtopCompositePixel): Replace AtopComposite with
        AtopCompositePixel, which passes the composite pixel by reference.

        * configure.ac: With excessive maintenance releases, the library
        age portion of MAGICK_LIB_VERSION was overflowing its allotted
        space.  This resulted in 1.1.X releases reporting the wrong
        MagickLibVersion as of 1.1.10.  Fix this by supporting up to 99
        values for each field.

2008-11-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Fix passing the --with-windows-font-dir option via
        DISTCHECK_CONFIG_FLAGS.

        * utilities/tests/msl_composite.sh: Integrated MSL composition
        test script contributed by Max Hohenegger, Max at hohenegger.eu.

        * magick/command.c (ConjureImageCommand): Return status was
        inverted so one was returned for command success rather than zero.

2008-11-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * png: Updated libpng to 1.2.33 release.

        * magick/color.c (FuzzyColorMatch): If fuzz is zero then
        completely use the result of ColorMatch() rather than entering
        unnecessary expensive code.

2008-10-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/studio.h: Make sure we don't conflict with OpenMP
        implementation if it is active but we are not using it.

2008-10-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/studio.h (HAVE_OPENMP): Add logic to make sure that
        OpenMP is only engaged for OpenMP 2.0 or later.

        * magick/command.c (VersionCommand): Report OpenMP version.

        * Makefile.am: The Magick++ build was supposed to be optional. Now
        it is.

        * Makefile.am: Eliminated .tar.bz2 and .zip packages from the
        distribution.  The .tar.bz2 package was hardly smaller than the
        .tar.gz package so it wasted 5.9MB with little benefit.  The
        compression ratio on the .zip archives is absolutely terrible so
        eliminating zip eliminates huge 9.6MB and 25MB files from the
        distribution equation.  Windows users can easily learn how to use
        the vastly more efficient 7-Zip format.

2008-10-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Rationalize OpenMP tests to make sure that OpenMP
        can not be enabled without thread support.

2008-10-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/composite.c (CompositeImageRegion): Add some minimal
        region limit checking.  Not completed yet.

        * magick/transform.c (RollImage): Accellerate using OpenMP.

2008-10-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/studio.h (omp_get_thread_num): Remove spurious trailing
        `;`.

        * magick/render.c (DrawPrimitive): Make method private since
        nothing else is using it.

        * magick/omp_thread_view.h (AccessThreadView): Inline function for
        a bit more performance.
        (AcquireOneThreadViewPixel) Inline function for a bit more
        performance.

2008-10-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * pragma omp parallel for: Use consistent static scheduling
        throughout and ensure that 64 threads can be usefully engaged on a
        1024 row image.

        * magick/pixel_iterator.c (SetRegionThreads): Implement logic so
        that pixel iterators execute single-threaded when invoked on tiny
        regions.

        * magick/pixel_cache.c (SetNexus): Make staging buffer memset()
        conditional in order to dramatically diminish impact to small
        accesses.  This memset() only exists to make valgrind happy.

2008-10-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (ReadTIFFImage): Fix progress monitor for the case
        of reading planar stripped images.

2008-10-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/effect.c (DespeckleImage): Accelerate using OpenMP.

        * magick/paint.c (OpaqueImage): Update to use pixel iterators.
        (TransparentImage): Update to use pixel iterators.

        * magick/decorate.c (FrameImage): Accelerate using OpenMP.
        (RaiseImage): Accelerate using OpenMP.

2008-10-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/composite.c (CompositeImageRegion): Start of new function
        to act as a lighter-weight yet more flexible image composition
        interface.

        * magick/transform.c (ChopImage): Accelerate using OpenMP.
        (CropImage): Accelerate using OpenMP.
        (FlipImage): Accelerate using OpenMP.
        (FlopImage): Accelerate using OpenMP.

        * magick/effect.c (ThresholdImage): Accelerate using OpenMP.

2008-10-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/pixel_cache.c (AcquireOneCacheViewPixel): Optimize
        implementation.

        * magick/effect.c (MedianFilterImage): Accelerate using OpenMP.

        (ImplodeImage): Accelerate using OpenMP.

2008-10-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/pixel_cache.c (GetCacheViewRegion): New function to
        return the region bounded by a pixel cache view.

        * magick/constitute.c (ExportViewPixelArea): New function to
        support exporting the pixels from a pixel cache view.
        (ImportViewPixelArea): New function to support importing pixels
        to a pixel cache view.

        * magick/pixel_cache.c (ReadStream): Eliminated function.
        (WriteStream): Eliminated function.
        (ClonePixelCacheMethods): Eliminated function.

        * magick/image.h: Eliminated StreamHandler call-back type.
        Eliminated ImageInfo stream member.

        * magick/pixel_cache.c (GetCacheViewArea): New function to return
        the area of a cache view.
        (AccessCacheViewPixels): New function to access already selected
        cache view pixels.

2008-10-19  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/fits.c: Remove unused exponential data.

        * magick/omp_thread_view.c: Move OMP Thread View functions out of
        pixel cache module and put them in this new module.

        * coders/xtrn.c (ReadXTRNImage): XTRNSTREAM mode was never
        implemented so remove unfinished stub code.

        * magick/pixel_cache.c: Exhuastive study of the pixel cache code
        reveals that it is inscrutable and not implemented in a fashion
        which enables useful multi-threading.  Therefore, the cache view
        interfaces are now made OpenMP-safe via a global critical section.

        * magick/pixel_iterator.c: Reduce use of critical sections around
        pixel cache to the bare minimum based on analysis and testing.
        Unfortunately, testing shows that the pixel cache views are still
        not 100% thread safe so the extra locking is still required.

        * magick/pixel_cache.c (ModifyCache): Make implementation thread

        semi-random `seed` value.
        (MagickRandReentrant): New function which works like rand() but
        attempts to be re-entrant if possible by allowing a seed value to
        be passed.

2008-08-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/channel.c (SetImageChannelDepth): Re-implement using

        part.  This required modification to all modules using the pixel
        iterator methods.

2008-07-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * wand/magick_wand.c (MagickCompareImageChannels): Use
        DifferenceImage().
        (MagickCompareImages): Implement by calling
        MagickCompareImageChannels().

        * magick/compare.c (DifferenceImage): The ImageMagick-compatible
        CompareImages() function signature was clearly an example of bad
        design so rename CompareImages() to DifferenceImage() with a
        signature which does not unnecessarily mix functionality and
        allows for ease of future expansion.

2008-07-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * wand/Makefile.am (WAND_TESTS): Added Wand drawtest and wandtest

        * coders/dcm.c (ReadDCMImage): Report actual image depth.

        * magick/resource.c (InitializeMagickResources): Set default
        maximum memory limit to physical memory rather than 2X physical
        memory.  This decision is made since the system paging device is
        often slower than files in the filesystem, and so memory mapping
        is likely faster.

        * magick/blob.c (OpenBlob): The MAGICK_IO_FSYNC environment
        variable causes output files to be synchronized to disk when set
        to TRUE.

        * magick/color.h (NotColorMatch): New macro for testing that two
        colors are not the same.  Opposite from existing ColorMatch().

        * magick/command.c: Replaced the many duplicate enum conversion
        code fragments with calls to functions in enum_strings.c.

        * magick/enum_strings.c: Absorbed the many "ToString" and
        "StringTo" functions from other source modules.

        * magick/effect.c (ThresholdImage): Optimize for larger images.

        * magick/constitute.c (ConstituteTextureImage): New function to
        return a texture canvas image based on a tile image.  Similar to
        existing TextureImage() except better optimized for creating new
        images and inherits tile image properties.

        * magick/color.h (IsBlackPixel): New macro to test if a pixel is
        black.
        (IsWhitePixel): New macro to test if a pixel is white.

        function rather than TextureImage().  Also allow the user to
        request a particular image type.

        * coders/pdf.c (Huffman2DEncodeImage): Explicitly request a strip
        per page when writing Group4 TIFF.

        * coders/tiff.c (WriteTIFFImage): Place a generous default limit
        on rows-per-strip when using Group3 or Group4 FAX compression.
        The default limit is added since it is observed that the Group4
        compressor fails with extremely huge strips.  Added a define
        "tiff:rows-per-strip" to allow the user to explicitly set the rows
        per strip.  Added a define "tiff:strip-per-page=true" to allow the
        user to force one strip per page no matter what.  Added progress
        monitor support to tile writer.

2008-06-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * VisualMagick/configure/configure.cpp: The MAT coder now depends

        (ExportImageChannel): Convert to use pixel iterators.

        * coders/dpx.c (WriteDPXImage): As an experimental feature, when
        the environment variable MAGICK_RESERVE_STORAGE is set to "TRUE",
        then the DPX format writer will request the required storage from
        the filesystem in advance (if supported by the OS) or the full
        amount of memory required (when writing to an in-memory BLOB).

2008-06-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/magic.c (InitializeMagicInfo): New function to initialize
        file format detection.

        rejecting bad files.

        * configure.ac: Eliminated --enable-delegate-build option that I
        have not used or tested for almost ten years so it probably did
        not work anyway.  Use --with-ttf=/prefix to specify the the
        installation prefix for freetype.  Use
        --with-ttf=/prefix/bin/freetype-config to specify the whole path
        to freetype-config.

        (MagickWhiteThresholdImage): Implemented.

        * magick/effect.c (BlackThresholdImage): Implemented a
        BlackThresholdImage() which is similar to (but not identical to)
        the one in ImageMagick.
        (WhiteThresholdImage): Implemented a WhiteThresholdImage() which
        is similar to (but not identical to) the one in ImageMagick.

2008-06-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/operator.c: Added support for additional channel
        operators (-operator) for applying noise to one or more channels.
        The additional operators are Noise-Gaussian, Noise-Impulse,
        Noise-Laplacian, Noise-Multiplicative, Noise-Poisson, and
        Noise-Uniform.  The amount of noise applied is controlled via the
        numeric argument, which can specify the percentage of noise to
        apply.

        * magick/enum_strings.c: New source module to contain the various
        EnumToString() and StringToEnum() functions which seem to multiply
        like bunny-rabbits.

        * magick/gem.c (GenerateNoise): Poisson noise generation was
        taking excessively long and producing wrong results.  Noise
        generation was only producing the correct amount of noise in the
        Q8 build.       
        (GenerateDifferentialNoise): New function to return noise in a
        floating-point differential format.

2008-06-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/pixel_iterator.h: Removed x,y coordinate information from
        all of the callback definitions since a use for this information
        has yet to be found.

        * magick/composite.c (CompositeImage): Use individual callback
        functions for the composition operations.

        * coders/xcf.c (ReadXCFImage): Deal with grayscale images the
        GraphicsMagick-way.

2008-06-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/effect.c (UnsharpMaskImage): Re-write implementation to
        use pixel iterators.

        * magick/pixel_iterator.c: Decided that the old per-pixel
        iterations were not useful enough to keep since the region-based
        ones are working fine.  Moved pixel_row_iterator.c to
        pixel_iterator.c and renamed functions to remove the `Row`
        designation.

        * magick/composite.c (CompositeImage): Automatically adjust
        colorspace of composite image so that it is compatible with canvas
        image.

        * magick/alpha_composite.h (AlphaComposite): Fix alpha composite
        when both pixels contain transparency.

        * PerlMagick/demo/demo.pl: Use segmentation parameters which
        are more suitable for our image.

2008-05-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/composite.c (CompositeImage): CMYK copy composition
        operators automatically set the image colorspace to CMYK.

        * coders/tiff.c (WriteTIFFImage): CMYK must take precedence over
        JPEG compression.  We don't support JPEG compression in TIFF with
        CMYK.

2008-05-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/effect.c (ChannelThresholdImage): Re-implement using
        pixel iterators.  Support thresholding only the red channel by
        eliminating the switch to intensity thresholding if only one
        channel parameter is supplied.

        * coders/tiff.c (WriteTIFFImage): Don't accidentially convert CMYK
        images to RGB.

        * magick/composite.c (CompositePixels): Handle CopyBlack properly
        for CMYK images.

        * magick/command.c (CompositeImageCommand):  Support CopyCyan,
        CopyMagenta, CopyYellow, and CopyBlack.

        colorspace.

        * doc/options.imdoc: Remove mention of thresholding at the channel
        level since this never worked in a useful fashion and now only
        simple intensity thresholding is available via -threshold.

        * magick/command.c (MogrifyImage): Revert to using ThresholdImage() rather
        than ChannelThresholdImage().

        * PerlMagick/Magick.xs: Revert to using ThresholdImage() rather
        than ChannelThresholdImage().

2008-05-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        iterators.

        * magick/pixel_row_iterator.c (PixelRowIterateDualNew): New pixel
        iterator.  Similar to existing PixelRowIterateDualModify except
        that this one is for when initializing a new image.

2008-05-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/composite.c (CompositeImage): Update image composition to

        * magick/enhance.c: Re-wrote all enhancement functions in this
        module to be based on the pixel iterator methods.

        * magick/command.c (ConvertImageCommand, MogrifyImageCommand,
        DisplayImageCommand): Gamma multiple channel syntax was broken.
        Now it is fixed.

2008-05-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/colorspace.c (RGBTransformImage): Optimized lookup table
        generation performance to the maximum extent possible.
        (TransformRGBImage): Optimized lookup table
        generation performance to the maximum extent possible.

        * magick/image.h (RoundDoubleToQuantum): New macro to explicitly
        safely round a `double` to a Quantum.
        (RoundFloatToQuantum): New macro to explicitly safely round a
        `float` to a Quantum.

        * configure.ac: Add OpenMP support library to LIBS so that
        dependent applications will pick up this dependency without
        themselves needing to enable OpenMP.

        * magick/command.c (CompositeImageList): Don't overwrite matte
        flag for CopyOpacity composition.

        * magick/composite.c (CompositeImage): CopyOpacity composition
        needs the opacity channel to be enabled.

        * PerlMagick/Magick.xs: Dissolve composition with Opacity was not
        working right.  Now it does.

2008-05-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/gem.c (HWBTransform): Hue value range was scaled wrong,
        leading to clipping.
        (TransformHWB): Hue value range was scaled wrong, leading to
        clipping.

        loops using PixelRowIterateMonoModify() in order to simplify the
        code.

        * magick/{pixel_iterator.h, pixel_row_iterator.h}: Pass pixel
        colormap index/indexes to callback functions.  Dependent code is
        adjusted to match.

        by the build.

        * configure.ac, Makefile.am: Install documentation according to
        the conventions established by the configure script.  This
        installs the documentation under
        /usr/local/share/doc/GraphicsMagick by default.

2008-05-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * scripts/format_c_api_docs: Add pixel_iterator.c and

        PixelRowIterateDualRead().
        (GetImageStatistics): Update to use PixelRowIterateMonoRead().

        * magick/pixel_row_iterator.h: New interfaces which are similar to
        the already existing interfaces in pixel_iterator.h except that
        they pass a row to the callback rather than one pixel.

        * magick/operator.c (QuantumOperatorRegionImage): Add progress
        monitor support.

        * magick/pixel_iterator.c (PixelIterateMonoRead): Add a
        `description` argument and progress monitor support.
        (PixelIterateMonoModify): Add a

        (PixelIterateDualModify): Add a
        `description` argument and progress monitor support.

        * magick/resize.c (HorizontalFilter, VerticalFilter): Switch back
        to RoundSignedToQuantum() since some pixels were experiencing
        underflow.  Localize some variables so that we don't have to
        declare them as private for OpenMP.

2008-05-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac, magick/resize.c, PerlMagick/Makefile.PL.in: Added
        OpenMP support for parallelizing a task across multiple cores.

2008-05-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac, magick/nt_base.h: Fix using libbz2 under MinGW.

        * coders/{msl.c, svg.c, url.c}: Fix compilation with modern
        libxml2 under MinGW.

2008-05-08  Josue Andrade Gomes  <josuegomes@gmail.com>

        * magick/nt_base.h, libxml/include/win32config.h (vsnprintf):
        Fixed compilation issue noticed with Visual C++ 2008.

2008-05-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/magick.c (GetMagickInfo): Simplify implementation.
        (RegisterMagickInfo): Remove any existing entry since module
        loading may result in duplicate entries.

2008-05-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtool: Update to libtool 1.2.4.

        * magick/magick.h (MagickInfo): Store string attributes as `const
        char *` to statically allocated data rather than as heap allocated
        strings.  THIS IS AN INTERFACE CHANGE.  Using a coder written to
        the old interface is non-fatal but may resemble a small memory
        leak.  The reason for the change is to avoid at least 880 needless
        malloc()/strlen()/strlcpy() operations at initialization time, and
        at least 880 free() calls at destruction time.  While these
        operations did not take long, they are still an unnecessary
        overhead, which is increased in thread-safe applications.

        * magick/module.c (OpenModule): Ignore requests to open modules
        which have already been opened.

        * GraphicsMagick.spec.in: Add --with-included-ltdl to the default
        options since this seems safest until the libltdl validation logic
        is fully robust.  This should be made user-configurable in the
        future.

        * magick/Makefile.am (magick_libGraphicsMagick_la_LIBADD): Apply
        libltdl dependency argument as required for building.

        * configure.ac: Intuit if the GraphicsMagick library will depend
        on -lltdl.

        * Magick++/bin/GraphicsMagick++-config.in: Use substitutions
        rather than invoking GraphicsMagick-config in order to determine
        GraphicsMagick library usage requirements.  This avoids problems
        when GraphicsMagick-config is not in the executable search path.

2008-05-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * GraphicsMagick.spec.in: NEWS was renamed to NEWS.txt.  Enable
        libtool verbose output so it is possible to diagnose build
        failures.

2008-05-01  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * mat.c: gm convert -limit Pixels 1 input_gray_lsb_16bit.mat crap.miff
        don't rotate partial image.

2008-04-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/magick.c (DestroyMagickInfoList): Use DestroyMagickInfo().
        (UnregisterMagickInfo): Use DestroyMagickInfo().
        (RegisterMagickInfo): Simplify dramatically by adding to the front
        of the list rather than maintaining alpha order.

        * magick/image.c (DestroyImageInfo): Tidy up and simplify code.

        * magick/constitute.c (WriteImage): Comment out the "bi-modal
        delegate" execution code until we determine what value it offers.
        The test suite passes without it.

        * magick/magick.h (struct MagickInfo): There is no need for `name`
        to be allocated data so make it const.  
        (DestroyMagickInfo): Add a static function to destroy a MagickInfo
        structure.  Renamed previous DestroyMagickInfo to
        DestroyMagickInfoList and made it static.

2008-04-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * version.sh: GraphicsMagick 1.2 released.
        CVS head is now 1.3 development.

        * png: Updated libpng to 1.2.27.

2008-04-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/image.c (SetImageInfo): Ignore file extensions which
        match defined virtual delegate entries (including stealth
        entries).

2008-04-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * BENCHMARKS.txt: Added timings for -blur.

2008-04-27  Darko Kojic  <dkc@sf.net>

        * magick/effect.c (MedianFilterImage): Fixes to compile on ARM
        CPU.

2008-04-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/magick.h (MagickInfo): Remove image_info member since I
        can not find any purpose for it.

        * coders/tiff.c (WriteTIFFImage): Remove assertion check on
        scanline size since it has not caught anything.

        * magick/image.c (SetImageInfo): Ensure that the file extension
        does not trigger unwanted activity such as access to an X11
        server, printer, or the launch delegate.

        * config/Makefile.am (configshare_DATA): Install colors.mgk in
        share path.

        * magick/blob.c (GetConfigureBlob): Search `share` config path
        prior to `lib` config path.

2008-04-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/png.c (WriteOnePNGImage): TrueColor RGB was usually
        written rather than the desired more compact format.  This is a
        first pass at fixing that.

2008-04-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * BENCHMARKS.txt: Added a benchmark summary.

2008-04-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * version.sh: Prepare 1.2beta1 release.

        * NEWS.txt: Updated with latest news.

2008-04-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtool: Update to 1.2965 2008-04-22

        * coders/png.c (ReadOneJNGImage): Deal with ReadImage() returning
        a NULL pointer when reading JPEG sub-image.

2008-04-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/channel.c (ExportImageChannel): Added progress monitor
        support.
        (SetImageChannelDepth): Added progress monitor support.
        (ChannelImage): Don't preserve matte channel when extracting
        channel.

        * magick/image.c (SetImageOpacity): Avoid integer overflow in Q32

        (GetImageBoundingBox): Added progress monitor support.
        (SortColormapByIntensity): Added progress monitor support.

2008-04-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac, magick/Makefile.am: Don't use libtdl unless we are
        supposed to be using it!

        * libtool: Updated to GNU libtool 1.2960 2008-04-19.

        * configure.ac, magick/delegate.h: It seems that the modern
        convention is to store ghostscript headers in a subdirectory
        called `ghostscript` rather than `ps`.
        We don't actually need Ghostscript errors.h and that is a good
        thing since it seems that some newer Ghostscript calls it ierrors.h

2008-04-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * VisualMagick/installer/inc/files-dlls.isx: Comment out inclusion
        of X11 support DLLs.

        * VisualMagick/magick/magick_config.h.in: X11 is no longer in the
        default Windows build.

2008-04-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/nt_base.c: Eliminate various annoying warnings noticed
        under MinGW.

        * magick/spinlock.h (_spinlock_release): Use `long` rather than
        `int` in order to eliminate warning under MinGW.

        * magick/semaphore.c (spinlock_wait): Use `long` rather than `int`
        in order to eliminate warning under MinGW.

        * magick/log.c (LogMagickEventList): Eliminate warning under MinGW.

        * magick/compress.h: Clean up interface definitions to use
        magick_uint8_t for unsigned character data.

        * coders/jpeg.c (ReadJPEGImage): Don't use GetPixelCachePresent()
        since it is not DLL-exported.

2008-04-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/yuv.c (ReadYUVImage): Report exception info correctly.

        * coders/xpm.c (ReadXPMImage): Report exception info correctly.

        * coders/xc.c (ReadXCImage): Report exception info correctly.

        * coders/tiff.c (ReadTIFFImage): Report exception info correctly.

        * coders/null.c (ReadNULLImage): Report exception info correctly.

        * coders/jpeg.c (ReadJPEGImage): Report exception info correctly.
        Use of Huffman optimization is now based on available memory
        rather than a hard-coded image size.

        * coders/gif.c (ReadGIFImage): Report exception info correctly.

        * magick/utility.c (MagickSizeStrToInt64): New function to convert
        a size string with optional units suffix to a 64-bit integer.
        (MagickStrToInt64): New function to convert a string to a 64-bit
        integer, with error checking.

        * magick/command.c: Eliminated the long-deprecated -cache resource
        limit option.

        * magick/resource.c: Complete re-write of the resource limit
        system.  Resource specifications are now absolute except that they
        support a binary metric suffix such as `K` to scale the value.
        Added the `Pixels` limit type to limit the maximum number of
        pixels allowed for each image.

2008-04-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/jpeg.c (WriteJPEGImage): Output grayscale images more

2008-04-09  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/png.c (ReadOnePNGImage) Use the low bits of the PNG
        tRNS values instead of scaling them when reducing from 16-bits.

2008-04-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Updated to Autoconf 2.62.

2008-04-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MogrifyImageCommand): New -create-directories
        option automatically creates subdirectories as needed when
        -output-directory option is used.  This is useful when one
        directory tree of files is being mogrified to a new tree.

2008-04-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/utility.c (MagickCreateDirectoryPath): New function to
        create a directory path.  Will be used later.
        * configure.ac: Tweaks to produce a successful MinGW cross-compile.

2008-04-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (WriteTIFFImage): Added a simple sentinel
        assertion to hopefully flush out any remaining cases where
        ExportImagePixelArea() writes past the end of its buffer.

        * magick/constitute.c (ExportImagePixelArea): GrayQuantum case for
        DirectClass pixels was sometimes writing a zero byte one past the
        end of the allocated buffer.  Thanks to Josue Gomes for reporting
        this bug.

2008-04-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/{pcd.c,pcx.c,pdb.c,pict.c,stegano.c,wpg.c,xcf.c}:
        Warnings reduction.     

        * magick/{channel.c,image.c,unix_port.c,render.c}: Warnings
        reduction.

        * coders/mat.c: Convert C99 comments to C89 comments so code can
        compile with a C89 compiler.

        * coders/tiff.c (WriteTIFFImage): Add an assertion to enforce that
        the bytes output to the scanline is no more than the bytes
        allocated for the scanline.

        * NEWS.txt: Updated with latest NEWS.

2008-04-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/pdf.c (WritePDFImage): Default to ZIP compression if
        available.  Ignore Image compression setting since the useful
        value (set by the user) usually comes from ImageInfo.

        * coders/png.c (WriteOnePNGImage): Fix progress monitor when
        writing PNG.

        * magick/channel.c (GetImageChannelDepth): Added progress monitor
        support.

        * libtool:  Update to libtool 2.2.2.

        * coders/jpeg.c: Convert more code to use size_t for sized values
        rather than long.

        * coders/wpg.c (InsertRow): Fix log format string specification.

        * coders/dpx.c (WriteDPXImage): Fix typo in casts.

        * coders/fpx.c (ReadFPXImage): Apply FreeBSD patch from Mikhail
        Teterin to allow FlashPIX to work better for 64-bit builds.
        Addresses SourceForge issue 1824658 "FPX should work again now".

        * magick/blob.c (ImageToBlob): Fix typo in cast.

2008-03-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * CONTRIBUTE.txt: Convert contribute.html to reStucturedText
        format and generate HTML version from it.

        * PROCESS.txt: Convert description of development process to
        reStucturedText format and generate HTML version from it.

        * INSTALL-windows.txt: Add instructions for how to install from
        setup.exe style installer.  Also add instructions for how the
        distribution package is built.

        * Copyright.txt: Reformat in reStucturedText format and generate
        HTML version from it.

        * VisualMagick/installer/inc/body.isx: No longer include
        development headers and libraries in the Windows DLL install
        package since they are large and they may only work with the
        version of Visual C++ used to perform the build.  It is much safer
        for the developer to build the package from source with his own
        compiler.

2008-03-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Fix compilation issues with Microsoft Visual Studio.

2008-03-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/dpx.c (ReadDPXImage, WriteDPXImage): Use lookup tables to
        speed up value conversion.

        * magick/memory.h (MagickAllocateArray): Renamed from
        MagickAllocateMemoryElements.

2008-03-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * PerlMagick/Magick.xs: Use memory allocation macros like the rest
        of the code.

        * magick/memory.c (MagickMalloc): New function which behaves
        similar to malloc().
        (MagickMallocArray): New function for allocating an array.
        (MagickRealloc): New function which behaves similar to realloc().
        (MagickFree): New function which behaves similar to free().
        (MagickAllocFunctions): New function to allow the user to specify
        the memory allocation functions.

        * magick/memory.h: New header file to define memory allocation
        functions.

        * magick/deprecate.c (DeleteImageList, DestroyImages,

        GetNumberScenes, GetPreviousImage, ParseImageGeometry,
        PopImageList, PostscriptGeometry, PushImageList,
        SetCacheThreshold, SetImageList, ShiftImageList, SizeBlob,
        SpliceImageList, UnshiftImageList): Remove functions which were
        already deprecated in ImageMagick 5.5.2 or earlier.

2008-03-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/dpx.c (WriteDPXImage): Support writing image which is
        already in a YCbCr colorspace.
        (ReadDPXImage): Return YCbCr images in YCbCr colorspace unless
        they are also Cineon log encoded.

        * magick/image.c (CloneImage): Use CloneImageAttributes().

        * magick/attribute.c (CloneImageAttributes): New function for
        copying image attributes from one image to another.

        * magick/utility.c (TranslateTextEx): Check if the pixel cache is
        initialized before using a function which requires using it.
        Thanks to Michal Kowalczuk for bringing this issue to my
        attention.

        * magick/attribute.c (SetImageAttribute): Only apply
        transformations to "comment" and "label" attributes.

        * magick/pixel_cache.c (GetPixelCachePresent): New function to
        test if the image pixel cache is present and initialized.

        ImageInfo to allocated image.
        (SetImageDepth): Use table lookups to improve performance.

2008-03-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MogrifyImageCommand): Added an
        -output-directory option to `mogrify` to send output files to the
        specified directory.

        * PerlMagick/t/read.t: Add input_logical_lsb_08bit.mat to
        PerlMagick tests.

        * magick/nt_feature.c (CropImageToHBITMAP, ImageToHBITMAP): Use
        GlobalFree() to free bitmap handle.

2008-03-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * PerlMagick/t/read.t: Added/adjusted WPG test files from Jaroslav
        Fojtik.

2008-03-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * AUTHORS.txt, BUGS.txt, FAQ.txt, NEWS.txt, PLATFORMS.txt,
        TODO.txt, INSTALL-unix.txt, INSTALL-windows.txt: Use

2008-02-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/constitute.c (ReadImage): Disable colorspace override
        code since it was being wrongly-triggered in X11 display commands.

2008-02-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/body.html: Update to mention 1.1.11 release.

2008-02-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/colorspace.c (RndToInt): Cast result to `unsigned int`
        rather than `int` in order to avoid possible value truncation with
        Q32 build.  Problem was reported by Kai-Uwe Behrmann.
        (TransformRGBImage): Fix loop iterator which was looping one past
        the end of the array.  Reported by Kai-Uwe Behrmann.

        * magick/command.c: Added a -set option to the composite, convert,
        display, mogrify, import commands in order to allow setting an
        image attribute.

2008-02-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * PerlMagick/Magick.xs: Use MagickAcquireMemory() rather than
        AquireMemory().

        * coders/xwd.c (ReadXWDImage): Eliminate integer overflow
        vulnerability (IDefense 09.19.07).

        * coders/xbm.c (ReadXBMImage): ditto

        * coders/xcf.c (ReadXCFImage): ditto

        * coders/dib.c (ReadDIBImage): ditto

        * coders/dcm.c (ReadDCMImage): ditto

2008-02-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (WriteTIFFImage): The RFC 3949 specification for
        Internet FAX recommends LSB2MSB fill order so document that.

2008-02-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (WriteTIFFImage): Use `-define
        tiff:fill-order={msb2lsb|lsb2msb}` to control TIFF bit fill order.

2008-02-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Updated to latest CVS libtool.

        * coders/tiff.c (CompressionSupported): Use
        TIFFGetConfiguredCODECs() to test if a requested compression type
        is supported by libtiff.  Based on advice from Frank Warmerdam.

        * configure.ac: Add test for TIFFGetConfiguredCODECs() in libtiff.

2008-02-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c: With libtiff 3.6.1, including tiff.h and tiffio.h
        is not sufficient to obtain the definitions from tiffconf.h so
        libtiff is assumed to not support any features, such as
        compression.  Avoid this problem by explicitly including
        tiffconf.h if it is found.  This resolves SourceForge issue
        [1883527] compression of tiff-file has no effect.

2008-02-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * VisualMagick/installer/inc/setup.isx: Set Inno Setup installer
        compression to "lzma/max".

        * PerlMagick/Magick.xs: Eliminate use of memory allocation macros
        since these failed miserably under Windows where it seems that
        malloc, free, and realloc are redefined via macros by the Perl
        build environment.  This reverts changes made on 2007-12-01.

        * magick/memory.c (MagickAcquireMemoryArray): Use implementation
        from the 1.1 branch.

        * magick/utility.h: Remove MagickSafeMultiplySize_t since it seems
        that use of inline functions in Windows is a disaster area.

2008-02-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Makefile.am (windows-dist): Create a 7z compressed Windows
        comprehensive source package.  See http://www.7-zip.org/ for
        information on Windows 7-Zip and http://p7zip.sourceforge.net/ for
        information on portable 7-Zip (P7ZIP).

2008-02-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        and resolution units.

        * magick/version.h.in: Update copyright year to 2008.

2008-02-01  Gary V. Vaughan  <gary@gnu.org>
        
        * configure.ac: Updated for libtool-2.1b.

        * bootstrap (libtoolize): Libtoolize can figure out the mode and
        directory for libltdl from configure.ac.

2008-01-28  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * magick/Makefile.am: Update
        magick_libGraphicsMagick_la_DEPENDENCIES to use LTDLDEPS.

2008-01-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/image.c (SetImageInfo): Successfully read existing file
        names in the form file[123] which were failing to read since they
        appear to be a valid sub-image specification.

2008-01-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/utility.c (ExpandFilenames): If a filename appears to
        contain a wildcard specification, first check to see if there is
        file matching the unexpanded wildcard prior to engaging in the
        slow task of wildcard expansion.  Without this fix, expanding the
        command line takes a very long time if there are a huge number of
        files in the directory, and some file names appear to contain
        wildcard specifications.  Inspired by SourceForge bug reports [
        1878992 ] "literal square brackets in file name cause large delay"
        and [ 1783209 ] "converting runs slowly when subimage is
        specified", but this might not be the complete fix for the
        problem.

2008-01-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Makefile.am: Update to Automake 1.10.1 and enable generation of
        an lzma compressed source package.

2008-01-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Added configure option --with-umem to enable use
        of the umem memory allocation library available in Solaris 9,
        Update 3 and later, or from
        https://labs.omniti.com/trac/portableumem/.  This library supports
        concurrency in multi-threaded programs and supports debugging
        memory issues.  See
        http://developers.sun.com/solaris/articles/libumem_library.html
        for a description of how to use the library for debugging memory
        issues.

2008-01-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (VersionCommand): Include a "Large Memory" item
        in the Feature Support list.

        * coders/png.c (RegisterPNGImage): Remove reference to dead PNG
        ftp site.

        * VisualMagick/configure/configure.cpp (InitInstance): Remove
        project dependency on dxguid.lib (Direct-X).

2008-01-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Update libtool to latest CVS version.

2008-01-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (DisplayImageCommand): No longer default to
        reading standard input if stdin fails isatty() test.  This
        behavior was causing failure to launch from Gnome and it is
        difficult to work around the issue from within a .desktop file. 
        (AnimateImageCommand): No longer default to
        reading standard input if stdin fails isatty() test.
