2009-12-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/unix_port.c (MagickSpawnVP): Remove unneeded new line
        character in error message format.

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

        * utilities/tests/annotate.sh: MSYS is garbeling up draw command
        so use a command file rather than using command line.

        * coders/{fits.c,meta.c,locale.c}: Fix benign warnings noticed
        under Cygwin 1.7.

        * magick/{constitute.c,resource.c,utility.c}: Fix benign warnings
        noticed under Cygwin 1.7.

2009-12-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/module.c (DestroyModuleInfo): If the Jasper library is
        used, then we can't invoke lt_dlexit() because this unloads the
        Jasper library and Jasper sometimes registers an atexit() cleanup
        handler.  Unfortunately, this may annoy memory leak checkers.

        * coders/jp2.c: Defer Jasper initialization to point of use.

2009-12-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * wand/magick_wand.c (MagickCdlImage): New method to apply the ASC
        CDL to an image.
        (MagickHaldClutImage): New method to apply a Hald CLUT to an image.

2009-12-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/studio.h atof(), atoi(), and atol() are legacy functions
        which might not be thread safe, might not enforce reasonable
        limits, and should not be used for new code.  So we implement them
        via strtod() and strtol().

2009-12-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * wand/magick_wand.c (MagickGetImageBoundingBox): New method to
        return the crop bounding box required to remove any solid-color
        border from the image.
        (MagickGetImageFuzz/MagickSetImageFuzz): New methods to get and
        set the color comparison fuzz factor

        * wand/pixel_wand.c (ClonePixelWand): New method to deep-copy an
        existing pixel wand.
        (ClonePixelWands): New method to deep-copy an array of existing
        pixel wands.

        * wand/magick_wand.c (MagickSetResolution): New method to set the
        wand resolution.  This one also works before the image has been
        read (unlike MagickSetImageResolution()).
        (MagickSetResolutionUnits): New method to set the wand resolution
        units.  Use in conjunction with MagickSetResolution().  This one
        also works before the image has been read (unlike
        MagickSetImageUnits()).

2009-12-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Magick++/demo/demo.cpp (main): Stop using deprecated functions.

        * wand/drawtest.c: Stop using deprecated functions.

2009-12-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/module.c (ModuleAliases): J2C is supported by the JP2
        coder.

        * coders/jp2.c: JP2 is now an alias for JPC since many files use
        that extension.  Problem reported by Stefano Acerbetti.

2009-12-09  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/png.c: The png8 encoder would fail when trying to write
        a 1-color image.  Problem reported by Bob Clark.

2009-12-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Define _GNU_SOURCE and _NETBSD_SOURCE so that
        pwrite() and pread() prototypes are available under GNU Linux and
        NetBSD.

        * coders/tiff.c: Warnings reduction.

        * magick/widget.c: Warnings reduction.

        * magick/segment.c (Classify): Warnings reduction.

        * magick/magic.c (struct StaticMagic): Length and offset can never
        be negative so use an unsigned type rather than size_t.

        * magick/render.c (TracePath): Fix access one beyond the end of
        the points array.

2009-11-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/gem.c (GetOptimalKernelWidth1D, GetOptimalKernelWidth2D):
        In the Q32 build, convolution kernel size was estimated
        incorrectly for large sigmas on 32-bit systems due to arithmetic
        overflow.

2009-11-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/effect.c (ConvolveImage): Moved here from fx.c since this
        is a more suitable place for it to be.

        * magick/enhance.c (GammaImage): Improve performance a bit.
        Preserve full precision in Q32 build.

2009-11-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/{channel.c,constitute.c,nt_base.h}: Start using the C'99
        `restrict` keyword.

2009-11-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * wand/magick_wand.c (MagickGetImageAttribute): New method to get
        an image attribute.  Patch contributed by Mikko Koppanen.
        (MagickSetImageAttribute): New method to set an image attribute.
        Patch contributed by Mikko Koppanen.

        * magick/constitute.c (ReadImage): Log subimage and subrange.

        * configure: Update to Autoconf 2.65.

        * magick/attribute.c (GenerateIPTCAttribute): Returned IPTC string
        values were one character too short.

2009-11-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/image.c (AllocateImage): The documented shorthand for
        specifying image size via filename[WIDTHxHEIGHT] was not working
        for raw formats which use the image tile_info data.

2009-11-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/image.c (ParseSubImageSpecification): Try to match
        behavior of previous sub-image specification parser.  Some
        incantations did not produce the same results.

        * win2k/IMDisplay/res/{IMDisplay.ico, IMDisplayDoc.ico}: Replaced
        with GraphicsMagick icon prepared by Jaroslav Fojtik.

        * coders/svg.c (ReadSVGImage): Use runtime initialization of
        SAXModules rather than static initialization.

        * magick/command.c: Commands now support reading an image from
        stdin in conjunction with a subrange specification (e.g. "-[1]").
        Problem was reported by Mario Becroft.

        * magick/common.h: New header file to incorporate the common bits
        shared by studio.h and api.h.

        * ltdl/ltdl.c: Update libltdl to 2.2.6b in order to fix security
        issue.  Resolves CVE-2009-3736 as it pertains to GraphicsMagick.

2009-11-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/constitute.c (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.  Problems were
        reported by Scott Kuhl.

2009-11-10  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/png.c: Also suppress new pedantic warnings from most
        older libpng-1.4.0 betas.

        * coders/png.c: Added a warning when attempting to use libpng-1.4beta
        older than 1.4.0beta67.

2009-11-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MogrifyImage): Only invoke ProfileImage() if
        an ICC CMS transform is to be performed.  Otherwise invoke
        SetImageProfile() to add the new profile.

        * magick/profile.c (ProfileImage): Improve logging messages.

        * coders/tiff.c (ReadTIFFImage): Allow CIELAB TIFF to be read.

        * coders/jpeg.c (ReadJPEGImage): Detect and apply colorspaces
        appropriately for ITU FAX JPEG.

2009-11-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tiff: Updated to libtiff 3.9.2.

2009-11-08  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/png.c: Suppress new pedantic warnings from libpng
        version 1.2.41 and 1.4.0 and later.

2009-11-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * doc/options.imdoc: Document difference between -recolor and
        Adobe Flash color matrix.

2009-11-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MogrifyImageCommand): Convolve does not accept
        an argument which looks like a geometry.  Resolves SourceForge
        issue #2890923 "Different handling of -convolve between convert
        and mogrify".
        (MogrifyImage): Validate that user-provided matrix is square when
        parsing -convolve and -recolor commands in order to avoid a core
        dump.

        * coders/tiff.c (ReadTIFFImage): Improved/added more coder logging
        statements.

        * magick/xwindow.c: Reflowed some code and comments.

        * magick/utility.c (SetClientName): Default client name does need
        to be "Magick", so original value is restored.

        * coders/mpc.c (ReadMPCImage): is_monochrome and is_grayscale
        flags were not managed properly for the MPC coder.

2009-10-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/jpeg.c (ReadJPEGImage): Added jpeg:block-smoothing and
        jpeg:fancy-upsampling defines to control these JPEG library
        options.

        * magick/image.c (SetImageInfo): Fix lockup due to hanging in loop
        while parsing malformed sub-image specification (SourceForge issue
        2886560).  Also fixes the ability to pass the image size via the
        filename specification like "myfile.jpg[640x480]" rather than
        needing to use -size.

        * coders/jpeg.c (ReadJPEGImage): Fix image scaling when used with
        IJG JPEG library version 7.

2009-10-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/resource.c: Added support for a "Threads" limit, which
        specifies how many threads may be used.  Note that if
        omp_set_nested(true) is used, GCC's GOMP seems to replicate this
        number of threads for each level of threading rather than sharing
        the specified number of threads across all teams.  For example,
        specifying four threads leads to sixteen active threads with
        omp_set_nested(true) and nested threading.  This GOMP behavior
        does not seem to cause any harm.
        (GetMagickResourceLimit): New accessor function to retrieve the
        maximum limit for a resource.

        * magick/module.c (ReadModuleConfigureFile): Default set of module
        aliases is now statically initialized.  The modules.mgk file is
        now optional and can be used to support adding more modules, or
        diverting existing format support to a user-provided module.

        * magick/magick.c (DestroyMagick): Document that this function
        should be invoked from the program's primary thread after any
        threads using GraphicsMagick have terminated.
        (GetMagickInfo): Was thread safe for access but not properly
        thread safe during initialization.  Is now fully thread safe.
        (InitializeMagick): Fully initialize everything needed to
        read/write files.  Document that this function MUST be invoked
        from the program's primary thread prior to using any other
        GraphicsMagick functions.

        * magick/color_lookup.c (ReadColorConfigureFile): The colors.mgk
        is now optional so don't throw an exception if it is not found.

        * magick/semaphore.c (AcquireSemaphoreInfo): Deprecated this
        internal function.  Use AllocateSemaphoreInfo() and
        LockSemaphoreInfo() instead.
        (LiberateSemaphoreInfo): Deprecated this internal function.  Use
        UnlockSemaphoreInfo() instead.

2009-10-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * config/colors.mgk: Colors.mkg is now empty since it is used to
        modify or extend the built-in color lookup table.

        * magick/{constitute.c,delegate.c,log.c,magic.c,magick.c,tempfile.c}:
        Explicitly initialize semaphores via InitializeMagick().

        * magick/type.h: New header file to contain types and function
        prototypes for functions in type.c.

        * magick/color_lookup.c (ReadColorConfigureFile): Store RGB color
        table in a static struct.  Entries in the colors.mgk file are now
        used to modify statically-defined entries, or add new definitions
        to the color table.

2009-10-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: --enable-libtool-verbose configure option is no
        longer needed now that we have silent build capability.

2009-10-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/attribute.c (GenerateEXIFAttribute): Add support for
        retrieving GPS EXIF attributes.  Based on work contributed by
        Jukka Manner.

        * Magick++/lib/STL.cpp, Magick++/lib/Magick++/STL.h (shadeImage):
        ShadeImage was the result of a botched cut-and-paste.  Corrected
        now.  Thanks to Jukka Manner for making me aware of this.

2009-10-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/analyze.c: New source file to contain image analysis
        functions.  Moved functions from image.c and color.c to this file.

        * magick/color_lookup.c: New source file to contain color lookup
        functions.  Moved associated functions from color.c to this file.

        * magick/ImageMagick.rc: Remove inclusion of magic.mgk.

        * magick/utility.c (MagickRoundUpStringLength): Use a bit less
        memory.

        * magick/color.c: Use most efficient string allocation function.

        * config/Makefile.am: Eliminate use of magic.mgk.

        * magick/magic.c: Store file header magic data in a static struct.

2009-10-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/describe.c (DescribeImage): Include composition operator
        in verbose output.  Also use CompressionTypeToString() to convert
        a compression enum to a string.

2009-10-11  Toby Thain  <qu1j0t3@users.sourceforge.net>

        * coders/psd.c: Further fix for 2783535 reported by Daniel Kirsch.
        Omit 0x0 layers from the image list, or they break compositing.

2009-10-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/xwindow.c: Check for overflow on all array allocations.

        * magick/command.c (MogrifyImages): If there is only one image in
        the list, then -flatten does nothing at all.

        * magick/transform.c (FlattenImages): If the user provides only
        one image then return a clone of that image rather than reporting
        an error.

        * magick/texture.c (TextureImage): If an under-texture is applied,
        then remove the matte channel.

        * magick/xwindow.c (MagickXMakeImage): Apply a checkerboard
        pattern when displaying non-opaque TrueColor images.  Fix a second
        integer overflow issue related to CVE-2009-1882.

2009-10-10  Toby Thain  <qu1j0t3@users.sourceforge.net>

        * coders/psd.c: Fix for 2783535 reported by Daniel Kirsch. PSD
        parser was confused by 0x0 pixel layers, resulting in image data
        corruption of all following layers.

2009-10-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/xwindow.c (MagickXMakeImage): Fix for CVE-2009-1882
        "Integer overflow in the XMakeImage function".  The problem is
        that the shared memory segment allocated may be smaller than the
        image size requires due to integer overflow.  On some systems it
        may be possible to crash GraphicsMagick (while displaying an image
        file) but not likely to overwrite the heap since shared memory
        segments are outside of the heap allocation.

        * magick/memory.c (MagickMallocArray): Use MagickArraySize().

        * magick/memory.c (MagickArraySize): New private function to
        compute the size of an array and return zero if it overflows the
        size_t type.

2009-10-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/dcm.c (ReadDCMImage): Handle (UN)known type VRs correctly
        and interpret the transfer syntax correctly.  Added define
        "dcm:avoid-scaling" to request that the coder should not scale
        image samples unless necessary (i.e. when bits used > quantum
        depth or maximum colormap depth, depending on image type).  Work
        is contributed by John Sergeant.

2009-10-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tests/Makefile.am (CHECK_PDF_FILE_COMPRESS): Add PDF tests with
        the various compression options.

        * coders/pdf.c (WritePDFImage): If the input file used JPEG
        compression and has not been converted to a bilevel or palette
        image, then use JPEG compression with original settings.  Problem
        was reported by Marco Atzeri.

2009-10-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * config/modules.mgk: DCRAW module entries were missing.

        * coders/tiff.c (WriteGROUP4RAWImage): Was not working properly on
        big-endian CPUs with libtiff 1.4.

        * coders/ps2.c (WritePS2Image): Use ImageToJPEGBlob().

        * coders/ps3.c (WritePS3Image): Use ImageToJPEGBlob().

        * coders/pdf.c (WritePDFImage): Decouple from libtiff.  Use ImageToJPEGBlob().

        * coders/dcraw.c (RegisterDCRAWImage): Needed to register module
        name.

        * coders/cals.c (ReadCALSImage): Fix bug in CALS reader which
        caused reading images taller than the image width to fail with an
        error.

        * magick/utility.c (AcquireString): Minor optimizations.
        (AllocateString): Minor optimizations.
        (CloneString): Minor optimizations.
        (LocaleCompare): Minor optimizations.
        (SubstituteString): Re-implemented in a more compact way which
        might avoid some reallocations.

        * magick/magick.c (ListModuleMap): Don't crash if `module` was not
        set.

        * magick/delegate.c (ListDelegateInfo): Fix insignificant memory
        leak.

        * magick/compress.c (ImageToJPEGBlob): Preserve JPEG settings if
        feasable.

2009-09-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/pdf.c (WritePDFImage): Use ImageToHuffman2DBlob() and
        ImageToJPEGBlob().

        * coders/cals.c (WriteCALSImage): Use ImageToHuffman2DBlob().

        (WriteJP2Image): Support writing JP2 files with arbitrary depth
        ranging from 2 to 16 rather than just 8 or 16.

2009-09-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/unix_port.c (MagickGetMMUPageSize): Cache returned page
        size to eliminated repeated system calls.

        * magick/operator.c (QuantumOperatorRegionImage): Fix missing
        percent in progress monitor message.

2009-09-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/meta.c (GetIPTCStream): Should return IPTC block length
        rather than remaining blob length.  Patch submitted by John
        Sergeant.

2009-09-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/meta.c (GetIPTCStream): IPTC blobs should be padded to an

        * coders/pcl.c (WritePCLImage): Use a different control code to
        (hopefully) eject the page.  Patch submitted by John Sergeant.

2009-09-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tests/Makefile.am: Add CALS tests.  Skip testing deep images for
        most formats which don't support deep images.

        * coders/cals.c: CALS module was not being built under Windows
        with MSVC.  Now it is.

        * VisualMagick/configure/configure.cpp (process_library): CALS
        module is dependent on TIFF library.

        * coders/cals.c (WriteCALSImage): Allow CALS writing at any time,
        but only enable CALS reader if libtiff is present at build time.

        * coders/{cals.c,pdf.c,ps2.c,ps3.c} (Huffman2DEncodeImage): Force
        TIFF image type to bilevel type.

        * config/modules.mgk, VisualMagick/bin/modules.mkg: CAL-->CALS
        rather than CALS-->CAL.

2009-09-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/benchmarks.rst: Updated GraphicsMagick vs ImageMagick
        benchmark results.

2009-09-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/cals.c (WriteCALSImage): Initial CALS Type 1 writer
        implementation.  Contributed by John Sergeant.

        * coders/png.c (ReadOnePNGImage): Fresh pixels should be set using
        SetImagePixels().

2009-09-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/msl.c, doc/conjure.imdoc: Add support for a new `profile`
        command in MSL/conjure which applies, adds, or removes one or more
        IPTC, ICC or generic profiles from a file.  Work contributed by
        John Sergeant.

2009-09-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/nt_base.c (NTGhostscriptFind): Make sure we close the
        registry key.  Log any Windows error messages.

        * magick/profile.c (AppendImageProfile): New function to add or
        append a profile.  If the profile already exists, then the data
        provided is appended to it.

        * coders/jpeg.c (ReadGenericProfile,ReadICCProfile,ReadIPTCProfile):
        Profile chunks need to be concatenated.  Otherwise "chunked"
        profiles become corrupted.

2009-09-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/average.c (AverageImages): Moved from image.c to new
        average.c file.

        * magick/colormap.h (VerifyColormapIndex): Moved here from color.h

        * magick/colormap.c (AllocateImageColormap): Moved from image.c to
        new colormap.c source file.
        (CycleColormapImage): Moved from image.c.
        (ReplaceImageColormap): Moved from image.c.
        (SortColormapByIntensity): Moved from image.c.
        (MagickConstrainColormapIndex): Moved here from color.c.

        * magick/describe.c (DescribeImage): Moved from image.c to new
        describe.c source file.

        * magick/plasma.c (PlasmaImage): Moved from image.c to new
        plasma.c source file.

        * magick/statistics.c (GetImageStatistics): Moved from image.c to
        new statistics.c source file.

        * magick/gradient.c (GradientImage): Moved from image.c to new
        gradient.c source file.

        * magick/texture.c (ConstituteTextureImage,TextureImage): Moved to
        new texture.c source file.

        * coders/svg.c (ENABLE_SVG_WRITER): Disable SVG writer by default
        since it usually does not work correctly and is unlikely to work
        correctly any time soon.

2009-09-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/profile.c (ProfileImage): GlobExpression is case
        sensitive so assure that its glob strings are always upper-cased.
        Without this fix, lower-cased arguments like "icm" would fail to
        be removed.  This would not be much of a problem except that the
        documentation claims that lower-case works.
        (SetImageProfile): Assure that profile names are upper-cased.

        * magick/fx.c (ColorMatrixImage): Add opaque opacity channel if
        image currently lacks an opacity channel but the matrix updates
        the opacity channel.  Requested by Kerry Panchoo.

2009-09-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/meta.c (GetIPTCStream): Updates from John.Sergeant to fix
        issues with IPTC record 2 blocks and to deal better with IPTC
        embedded in an 8BIM profile.

        * PerlMagick/t/read.t: Added tests for Topol format.

2009-09-12 Fojtik Jaroslav  <JaFojtik@seznam.cz>
        * coders/topol.c: Pallette overflow fixed for subtype 3.

2009-09-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * utilities/tests/msl_composite.sh: Use a draw command file for
        this test script too.

        * utilities/tests/{black-threshold.sh,draw.sh,recolor.sh,
        white-threshold.sh}: MSYS is sometimes wreaking havoc on arguments
        with spaces in them so use work-arounds.

2009-09-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/nt_base.c (NTGhostscriptFind): Improve logging messages
        when searching for Ghostscript.

2009-09-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/pixel_cache.c (CacheInfo): Add read_only member to
        indicate if cache is allowed to be modified.
        (ModifyCache): Clone cache if origin cache is read only.
        (PersistCache): Persistent caches which are attached are treated
        as read-only.  This avoids crash with MPC images which are read
        and subsequently modified.
        Reverted pixel cache locking changes which were made yesterday
        since I decided that they were too risky until file handle
        management is addressed.

2009-09-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/resource.c (InitializeMagickResources): Increase
        operating system file handle limits if necessary.

        * magick/pixel_cache.c: Pixel cache file locking is now done at
        point of access.

        * magick/nt_base.c (NTGhostscriptFind): New function to find
        Ghostscript under Windows, replacing previous Ghostgum
        implementation.

        * Copyright.txt: License is now based on MIT license exactly,
        without extra edits.  Ghostgum code has been eliminated so it is
        no longer necessary to include its license.

2009-09-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/delegate.c (GetPostscriptDelegateInfo): Add a gs-palette
        delegate entry in order to force Ghostscript to output a
        colormapped image if `-type palette` is specified prior to the
        input filename.  Ghostscript's dithering is much courser than
        GraphicsMagick's -colors default (more similar to
        -ordered-dither), but it is fast and produces smaller intermediate
        files.

        * coders/ps.c (ReadPSImage): Eliminate use of NULL pointer when
        progress monitor is enabled.  Was referring to image->filename
        rather than image_info->filename as it should have.

        * magick/delegate.c (InvokePostscriptDelegate): Added an
        `exception` argument so that failure details can be returned.
        Tried to reorganize the code so that it is more tolerant of errors
        such as a dynamically-loadable DLL failing to load.  On POSIX
        systems, Ghostscript was not being invoked as securely as
        expected.

        * coders/Makefile.am: Only build the DPS module if the Display
        Postscript library is available.

        * coders/ept.c (ReadEPTImage): If we don`t have the Display
        Postscript library, then don't try to use it as a fallback.

        * coders/ps.c (ReadPSImage): If we don't have the Display
        Postscript library, then don't try to use it as a fallback.

        * magick/blob.c (CloseBlob): If blob was never allocated, then
        don't try to close it.

2009-09-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/index.rst: Mention 1.2.8 release.

2009-09-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Magick++: New Image methods cdl(), colorMatrix(), and haldClut()
        added.

2009-09-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/shear.c (IntegralRotateImage): Select tile sizes in a
        more intelligent fashion.

        * magick/pixel_cache.c (GetPixelCacheInCore): New private pixel
        cache method to see if image pixels are in core.

2009-09-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/constitute.c (ReadImage): No longer clear the exception
        at the start of ReadImage() and other similar functions.  If the
        user of the function cares, she can clear the exception in
        advance.  It is not right to overwrite exceptions which might not
        have been reported/handled yet.

        * magick/shear.c (IntegralRotateImage): Rotate by zero degrees
        does not need to do any work.

        * coders/*.c, magick/*.c: Include image dimensions in progress
        monitor output when loading or saving a file.  Eliminate redundant
        text from progress messages.

2009-08-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/wmf.c: Eliminate memory leaks.

        * magick/render.c (DrawDashPolygon): Avoid access beyond end of
        array.  Resolves SourceForge issue 2832125 "Crash on SVG
        conversion".

        * coders/png.c (ReadOnePNGImage): Ensure that opacity channel is
        properly initialized.  Resolves SourceForge issue 2831240
        "Possible alpha channel issue with PNG w/palette and tRNS".

2009-08-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/nt_base.h (HAVE_TIFFSWABARRAYOFTRIPLES): Need to define
        this since libtiff includes this function now.

        * VisualMagick/tiff/libtiff/tiffconf.h.in: Enable all the options
        by default.

        * tiff: Updated to libtiff 3.9.1.  3.9.0 was broken.

2009-08-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/profile.c (MagickFreeCMSTransform): Add a CMS transform
        destructor since otherwise Visual Studio does not like it.

        * tiff: Updated to libtiff 3.9.0.

2009-08-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (TimeImageCommand): Add a simple `time`
        sub-command to time the execution of any other GraphicsMagick
        sub-command.  Similar in concept to the `benchmark` sub-command
        but produces output similar to the `time` command offered by the
        zsh command shell.  Handy for when `time` is not available, or
        consistent output is desired.

        * magick/magick.c (MagickGetFileSystemBlockSize): New private
        function to allow getting desired filesystem block size.
        (MagickSetFileSystemBlockSize): New private function to allow
        setting desired filesystem block size.

        * magick/pixel_cache.c (WriteCacheIndexes, WriteCachePixels):
        Temporarily disable pixel cache row coalescing when writing to
        disk until we come up with a good way to optimize write sizes.

        * coders/meta.c (ReadMETAImage): Fix memory leak of profile blob.

2009-08-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * utilities/tests/icc-transform.sh: Add a sanity-test for applying
        ICC profiles.

        * magick/profile.c (ProfileImage): Improve OpenMP performance.

2009-08-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/render.c (DrawPolygonPrimitive): Drawing of points,
        lines, and polygons is now accelerated using OpenMP with good
        speed-up.

2009-08-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * wand/drawing_wand.c (DrawClearException): New function to clear
        drawing wand exception.
        (DrawGetException): New function to retrieve information regarding
        the last drawing wand exception (if any).
        (DrawRender): DrawRender() is now deprecated since it requires an
        Image pointer to be embedded in the drawing wand.  The image
        passed is subsequently lost by CloneDrawingWand() since it must
        clone the image using copy-on-write.  Subsequent use of
        DrawRender() on a cloned wand scribbles on an image the user does
        not have access to.  Use existing Wand function MagickDrawImage()
        instead.
        (DrawAllocateWand): DrawAllocateWand() is now deprecated since it
        requires passing an Image pointer into the drawing wand.  Use
        existing DrawingWand function NewDrawingWand() instead.

2009-08-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * wand/drawing_wand.c (CloneDrawingWand): New function to
        deep-copy a drawing wand.
        (NewDrawingWand): Use a boolean flag to track if image is
        allocated by the wand, or by the user.  Most of the previous
        DrawAllocateWand() code is moved into NewDrawingWand() so that the
        boolean flag is easy to manage.

2009-08-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (WriteTIFFImage): Support writing grayscale
        JPEG-compressed TIFF.

2009-08-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (ReadTIFFImage): Don't override the photometric
        for grayscale JPEG-compressed TIFF.

2009-08-08  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/png.c: Made compatible with libpng-1.4.0beta74 and later
        (won't work with libpng-1.4.0beta35 through beta73) due to change
        in names of png_struct members "trans" and "trans_values"). 

2009-08-08 Fojtik Jaroslav  <JaFojtik@seznam.cz>
        * coders/topol.c: Pallette is ignored for subtype 5 (RGB).

2009-08-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/{cineon.c, dpx.c, locale.c, svg.c}, magick/{attribute.c,
        effect.c, utility.c}: Eliminate warnings reported by GCC 4.4.0.

2009-07-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Try to be more insistent about compilation failure
        if libjpeg version is less than 6b.  IRIX compiler only warns
        about #error preprocessor statement.

2009-07-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * wand/magick_wand.c (MagickSetCompressionQuality): New Wand
        method to allow setting the compression quality.

2009-07-29 Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/topol.c: Fixed missing break. Added response to ping.

2009-07-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/pcx.c (ReadPCXImage): Detect improper rows, columns, or
        depth.  Fixes CVE-2008-1097 "Memory corruption in ImageMagick's
        PCX coder".

        * configure.ac: Update to Autoconf 2.64.

2009-07-25 Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/topol.c: Fixed several issues. Added possibility to read
        TopoL level 2 images.

2009-07-25 Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * VisualMagick\configure\configure.cpp: Fixed library absolute path issue.

2009-07-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/random.c (DestroyMagickRandomGenerator): Trick to free
        thread specific random kernel contexts simply locks up with MSVC's
        OpenMP, so remove this functionality.

2009-07-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/random.c (DestroyMagickRandomGenerator): Cleanup thread
        specific random kernel data.

        * magick/tsd.c (MagickTsdKeyCreate): Fix glitch when built without
        any threads support.

2009-07-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/benchmarks.rst: Update GraphicsMagick vs ImageMagick image
        processing benchmark results.

2009-07-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/OpenMP.rst: Update performance measurements for readily
        available systems.

        * NEWS.txt: Updated to reflect latest changes.

2009-07-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * png: Updated libpng to 1.2.38.

2009-07-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/image.c (GetImageInfo): Default interlace for ImageInfo
        is now UndefinedInterlace so that it is possible to preserve the
        original interlace setting for the image file.  Code depending on
        the previous default setting of NoInterlace is adjusted to suit.
        This is a potentially risky change given the brittle nature of
        some of the legacy code.

        * coders/tiff.c (ReadTIFFImage): Stripped reader needs to read
        planar TIFF plane-wise in order to work with libtiff's internal
        buffering.
        (ReadTIFFImage): Tiled reader needs to read planar TIFF plane-wise
        in order to work with libtiff's internal buffering.
        (WriteTIFFImage): Tiled writer needs to output planar TIFF
        plane-wise in order to work with libtiff's internal buffering.

2009-07-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MontageUsage): Reconcile montage help output
        with actual montage options.

2009-07-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (WriteTIFFImage): Allow the user to be able to
        specify rows_per_strip when using JPEG compression.  The
        rows_per_strip value rounded up to the nearest multiple of 16.

2009-07-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (WriteTIFFImage): Add the ability for the user to
        manually specify the predictor using syntax like `-define
        tiff:predictor=2`.

2009-07-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/quantize.c (QuantizeImages): Avoid crash when using
        -monitor +map on an image list.

        * magick/command.c (BenchmarkImageCommand): Send benchmark report
        to stderr so that it does not interfer with pipes.

        * magick/cdl.c (CdlQuantum): Add range limiting of value before
        applying power function.

        * coders/dpx.c (ReadDPXImage, WriteDPXImage): Using floating point
        calculations when building sample value lookup tables in order to
        decrease error.  In particular input values were being scaled too
        low, resulting in improperly rounding down during processing of
        the image.

2009-07-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/pdf.c (WritePDFImage): Incorporated updates from John
        Sergeant to remove the font and thumbnail objects from PDF output.

2009-07-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/cdl.c (CdlImage): New function to apply an ASC CDL
        transform to the image.  Original implementation by Clément Follet
        from Workflowers but considerably re-worked by Bob Friesenhahn.
        Available as -asc-cdl via the `convert` and `mogrify` subcommands.

2009-07-04 Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * www/formats.rst: MAT module can read compressed files.
        Remove warning about unsupported compression.

2009-07-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/dcm.c: Eliminate compiler warnings.

2009-07-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/dcm.c: Significant re-write of the DICOM reader.  Work
        contributed by John Sergeant.

2009-07-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/blob.c (OpenBlob): Subsequent research shows that Direct
        I/O will not be useful to ordinary file I/O due to specific
        requirements for buffer alignments and I/O sizes.  Support for
        requesting it is removed.

2009-07-01  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * www/formats.rst: ART module has writer for more than year.
        So mark this here.

2009-06-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac, magick/blob.c: Add experimental Solaris direct I/O
        support which is enabled by setting the environment variable
        MAGICK_DIRECTIO to TRUE.  Direct I/O bypasses the filesystem
        cache.  Only works for NFS and UFS, and not for ZFS.

2009-06-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * rungm.sh.in: Fix environment variable issues noticed while
        running the test suite under MinGW.

        * Makefile.am (TESTS_ENVIRONMENT): Fix environment variable issues
        noticed while running the test suite under MinGW.

        * magick/hclut.c (HaldClutImage): Don't convert Cineon Log to RGB.

2009-06-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MogrifyImageCommand): Cache mogrify argument
        images so that they are only loaded once when mogrify is used to
        process multiple image files.

        * coders/dpx.c (WriteDPXImage): Fix leak of chroma image when
        subsampling to 4:2:2.

2009-06-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/utility.c (ExpandFilenames): Expand @filename to a list
        of arguments.

2009-06-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MogrifyImageCommand): Fix memory leak of
        output_directory string buffer, if it was used.

        * magick/utility.c (ExpandFilenames): Input wildcard file
        specifications with a subdirectory component such as
        "subdir/*.dpx" were not working.

2009-06-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/magick.c (InitializeMagick): Invoke InitializeMagickRegistry().

        * magick/registry.c (RegistryInfo): There is no reason to expose
        the RegistryInfo structure in the public interface so it is moved
        to registry.c.
        (InitializeMagickRegistry): Add a function for initializing the
        magick registry.

2009-06-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (CompareImageCommand): Report full error rather
        than rounded error in error reports since sometimes the value
        reported was rounded down to zero.

        * utilities/tests/hald-clut-transform.sh: New test to verify that
        Hald CLUT interpolation is working perfectly.

        * utilities/tests/hald-clut-identity.sh: Renamed from
        hald-clut.sh.

2009-06-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/jpeg.c (RegisterJPEGImage): Fix typo which caused IJG
        library version to be shown for "JPG" format but not for "JPEG".
        Also use a more descriptive name for JPEG library.

        * magick/image.c (DescribeImage): Filter out spurious EXIF
        attributes which already exist because we previously accessed
        them.  We do a full EXIF dump later.

2009-06-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/FAQ.rst: Add a FAQ about how to process many files at once.

2009-06-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Reduce usage of deprecated Autoconf macros.

2009-06-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: User provided LDFLAGS was being overwritten under
        Solaris.
        * Many files: Additional reduction of shadowing warnings.

2009-06-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MogrifyImage): Fix leak of the entire mask
        image supplied via -mask.

        * utilities/tests/mask.sh: Add a test for applying a mask image
        with -mask.

2009-06-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/attribute.c (GenerateEXIFAttribute): Identify unknown
        tags via their four-character hex value.

        * magick/colorspace.c (CMYKToRGBTransform): Use symbolic notation
        to access pixel quantum values.

        * utilities/tests/identify.sh: Added a test for `identify
        -verbose` on a well-populated JPEG file.

        * PerlMagick/t/{jpeg/write.t, jng/read.t, jng/write.t}: Relax
        allowed error for JPEG-related tests.

        * magick/attribute.c (GenerateEXIFAttribute): Attribute allocation
        size was too small causing overrun of memory buffer.  Problem was
        added on 2009-06-08.

        * magick/image.c (AllocateDepthMap): Allocation size was one
        element too small.
        (GetImageDepth): Forgot to free depth map.  Memory leak of 64K
        bytes per iteration.

2009-06-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/{mat.c, miff.c, pdf.c, ps3.c}: Have Zlib use our memory
        allocators.

        * magick/memory.c (MagickMallocCleared): New memory allocation
        interface which is similar to MagickMalloc() except that returned
        memory has been cleared first.

        * magick/hclut.c (HaldClutImagePixels): Fix wrong accesses
        detected by valgrind.  Also improve execution performance.

        * coders/xwd.c (WriteXWDImage): Fixed valgrind memcheck complaint

2009-06-09  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/txt.c Handle alpha channel for ImageMagick's alternative .txt

2009-06-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/dpx.c (WriteDPXImage): Fixed valgrind memcheck complaint
        about access to uninitialized data.

        * magick/attribute.c (GenerateEXIFAttribute): For EXIF STRING,
        output unprintable characters using three-digit octal notation.

        * coders/dpx.c (WriteDPXImage): Assure that offset count is
        correct according to reported bytes written.

        * utilities/tests/hald-clut.sh: Add a simple identity test for the
        Hald CLUT support.

2009-06-07  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/txt.c Handle alpha channel for ImageMagick's .txt

2009-06-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/hclut.c (HaldClutImage): Add a Hald CLUT capability as
        described at http://www.quelsolaar.com/technology/clut.html.  This
        allows a color transformation to be easily created and replicated
        on any number of images.  The algorithm is accessed by the
        -hald-clut option of `convert` and `mogrify`.  The original
        algorithm is by Eskil Steenberg and was adapted for GraphicsMagick
        by Clément Follet from Workflowers with support from Cédric
        Lejeune of Workflowers.

2009-06-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/utility.c (GetMagickGeometry): Support `^` modifier to
        geometry specification which indicates that specified size is a
        minimum bounding box rather than a maximum bounding box while
        preserving the image aspect ratio.

2009-06-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/resource.c (ListMagickResourceInfo): If supporting
        OpenMP, then include a "Threads" limit in the output of `-list
        resource`.

        * coders/pnm.c (ReadPNMImage): Fix multi-thread issue detected by
        valgrind's helgrind tool.  Diminish compilation warnings.

        * coders/dpx.c (ReadDPXImage): Diminish compilation warnings.

        * magick/random.c (AcquireMagickRandomKernel): Fix potential
        multi-thread issue detected by valgrind's helgrind tool.

        * magick/magick.c (InitializeMagick): Semaphore subsystem needs to be
        initialized before anything which uses it.

        * magick/semaphore.c (InitializeSemaphore): Since we are using
        PTHREAD_MUTEX_INITIALIZER to initialize primary POSIX mutex in the
        semaphore subsystem, we should not explicitly initialize the
        semaphore a second time.

        * magick/segment.c (Classify): Fix multi-thread issue detected by
        valgrind's helgrind tool.

        * magick/render.c (DrawAffineImage): Use InterpolateViewColor() to
        evalute a bi-linear interpolated point rather than obtaining a
        pixel value from a close pixel.  This provides better results.

2009-06-02  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/txt.c Attempt to handle alpha channel.

2009-06-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/pixel_cache.c (InterpolateViewColor, InterpolateColor):
        Moved from gem.c.  Gem functions should not be accessing the pixel
        cache.

2009-06-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (CompareImageCommand): Add a -maximum-error
        option to `compare` so that it can easily be used in boolean logic
        when comparing images.

2009-05-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tests/Makefile.am (TESTS_XFAIL_TESTS): If Ghostscript is not
        available then XFAIL the tests which depend on it.

        * magick/pixel_cache.c (GetCacheInfo): Assure that allocated
        stuctures do not occupy the same cache lines.

2009-05-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/studio.h (MAGICK_CACHE_LINE_SIZE): Allow cache line size
        to be set in one place in case we want to configure for it later.

        * magick/effect.c (AllocateMedianList): Assure that allocated
        stuctures do not occupy the same cache lines.

        * magick/random.c (AcquireMagickRandomKernel): Assure that
        allocated random kernels do not occupy the same cache lines.

        * magick/gem.c (GenerateDifferentialNoise): User is required to
        supply random kernel.

        * doc/options.imdoc: Document -format "%p".  Problem was reported
        by Stijn Sanders.

2009-05-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/Makefile.am (coders_tiff_la_LIBADD): Libtiff may now also
        depend on libjbig and the math library.

        * doc/gmdoc2html: Fix link to ball.png.  Problem was reported by
        Wes Fox.

        * VisualMagick/installer/inc/files-documentation.isx: Include Wand
        API documentation.

        * VisualMagick/installer/inc/icons-associate.isx: Fix Windows
        Start menu link to web pages.

        * configure.ac: --with-perl is changed to --without-perl since
        building PerlMagick is no longer the default.  Building PerlMagick
        automatically has caused too many problems.

        * PerlMagick/Makefile.am: GraphicsMagick no longer automatically
        installs PerlMagick.  Use the procedure described by
        PerlMagick/README.txt to build and install PerlMagick.

2009-05-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Debian stores Ghostscript fonts under
        /usr/share/fonts/type1/gsfonts so check there for fonts.  Issue
        reported by Ralf Wildenhues.

2009-05-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * PerlMagick/Magick.xs: Fix Ping of blob.

        * PerlMagick/t/ping.t: Added tests for pinging files and blobs.

        * www/perl.rst: Ping blob syntax is like $image->Ping(blob=>@blob).

        * PerlMagick/Makefile.PL.in: Increase the probability of
        PerlMagick build success by using the user-specified C compiler as
        the linker if the C compiler was already used as the linker.  This
        helps if the C compiler used to build GraphicsMagick is a more
        recent vintage than the one used to build Perl.

        * PerlMagick/t/wmf/read.t: Test needs to be more lenient for
        Linux.

        * Makefile.am (TESTS_ENVIRONMENT): Pass a complete text
        environment so that we don't need to execute rungm.sh in order to
        run the test suite.

2009-05-25  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * version.sh: Define PACKAGE_STRING.

2009-05-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/tempfile.c (ComposeTemporaryFileName): Use new random
        number generator.

        * magick/random.c: Implement a random number generation system
        based on George Marsaglia's multiply-with-carry generator.
        Somewhat slower than rand() but produces better random numbers
        with a period >2^60.  Suggested by Mark Mitchell.

2009-05-24  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/txt.c Small optimization:

        Before: 2000 iter 34.08s user 34.24s total 58.420 iter/s

        After: 2000 iter 21.55s user 21.76s total 91.891 iter/s

2009-05-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Makefile.am (XFAIL_TESTS): Handle the case where FreeType is not
        available by marking tests dependent on FreeType as XFAIL.
        (TESTS): Reorder TESTS so that there will be no trailing spaces
        since this confuses certain older versions of GNU make.

2009-05-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/tempfile.c (ComposeTemporaryFileName): Use simpler code
        (suggested by Mark Mitchell) to compute the substitution index.
        (AcquireTemporaryFileDescriptor): Try harder to generate a
        successful temporary file and fall through to alternative
        implementations if the first does not succeed.

        * magick/magick.c (InitializeMagick): Use MagickRandNewSeed() to
        seed the default random number generator.

        * magick/utility.c (MagickRandNewSeed): Include PID in random
        number seed generation.

2009-05-22  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/txt.c Fixed char vs int parameter problem.
        Better detection of too dark 16bit or 32bit images.

2009-05-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Makefile.am (AUTOMAKE_OPTIONS): Enable parallel-tests and
        color-tests options.  Parallel test execution does not pass tests
        yet.

        * PerlMagick/PerlMagickCheck.sh.in: Run PerlMagick tests via a
        normal check script rather than a check hook.

        * coders/identity.c (ReadIdentityImage): Fix compilation with Sun
        compiler.

2009-05-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tests/rwfile.c: Allow the user to specify the basename for
        temporary files.

        * tests/Makefile.am: Add a set of TXT read/write tests.  Pass the
        file name specification to use for the rwfile-based tests.

2009-05-21  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/txt.c Fixed endian set to native endian.

2009-05-20  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/txt.c Faster read ImageMagick files.
        Removed BImgBuff=NULL;

2009-05-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/txt.c (WriteTXTImage): Ensure that image depth is 8, 16,
        or 32.

        * www/formats.rst: Add CALS to formats list.

        * coders/cals.c (RegisterCALSImage): Consolidate duplicate text
        strings.

2009-05-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/cals.c: Add support for reading CALS type 1 format.
        Contributed by John Sergeant.

        * coders/identity.c: New coder to return a Hald identity CLUT
        image.

2009-05-19  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/txt.c Ability to read back Q32 txt files.

2009-05-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Support Linux style silent build rules.

2009-05-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Makefile.am: Updated to Automake 1.11.

2009-05-17  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/txt.c First attempt to read back txt file.
        It is amazingly ineffective, but it seems to work.

2009-05-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/resize.c (HorizontalFilter, VerticalFilter): When
        resizing a non-opaque image, attenuate the influence of
        surrounding colors based on their degree of transparency in order
        to avoid "halos" around objects caused by colors which are
        transparent and therefore not part of the visible image.  Patch
        contributed by Pavel Merdin via SourceForge Tracker #2792322.
        (VerticalFilter, VerticalFilter): Additional clean-up and
        optimizations.

2009-05-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MogrifyImage): Added a -recolor command option
        to provide access to ColorMatrixImage().

        * magick/fx.c (ColorMatrixImage): New function to apply a color
        matrix similar to Adobe Flash Flash.filters.colorMatrixFilter(),
        and Windows GDI+ ColorMatrix class, (order up to 5x5) to the image
        pixels.

2009-05-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/perl.rst: Add missing PerlMagick debug event types.

        * coders/pcl.c: Major improvements from John Sergeant.  These
        include: 1) Fixed 2 bit output where Max=BLACK - this always
        produced negative images even when -negate was passed as a
        parameter. The code now uses a two element palette to handle this
        situation.  2) Added support for 8 bit pseudoclass images.  3)
        Changed the coder to allow adjoin, placing each sub-image on a new
        page.  4) Added support for compression. Any compression other
        than "None" will cause the coder to to try to calculate and pick
        the best out of the PCL set of RLE, Tiff RLE or delta compression
        on a per row basis, as well as handling repeated rows and zero
        rows intelligently.

2009-05-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * utilities/Makefile.am (MAGICKPROGRAMS): Add a `compare`
        ImageMagick compatibility link.

        * INSTALL-unix.txt: Apply patch regarding GnuWin32 from John Wye,
        SourceForge #2779009.

2009-05-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Add the LDFLAGS option -Wl,-zlazyload when using
        the Solaris linker.

2009-05-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/url.c (ReadURLImage): Fix typos.

2009-05-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/utility.c (SystemCommand): Added access confirmation
        checks for external commands.

        * magick/unix_port.c (MagickSpawnVP): Added access confirmation
        checks for external commands.

        * coders/url.c (ReadURLImage): Added access confirmation checks
        for URLs.

        * magick/blob.c: Added access confirmation checks for files.

        * magick/confirm_access.c (MagickConfirmAccess): Added an access
        confirmation facility to allow the API user to monitor and/or
        block access to files and URLs.  This allows the API user to
        implement a security policy based on actual accesses.

2009-05-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * png: Updated libpng to 1.2.35.

        * lcms: Updated lcms to 1.18a.

2009-05-01  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/png.c (WriteOnePNGImage and WriteOneJNGImage): Changed
        internal attribute png_bit_depth to png:bit-depth-written to avoid
        confusion with planned new public png:bit-depth attribute.

2009-04-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/command.c (MogrifyImages): Deal slightly better with the
        case when MogrifyImage() expands one image into several.  Still
        don't know of a sane way to deal with -crop WIDTHxHEIGHT.

        * magick/transform.c (TransformImage): Image which is updated may
        be a list so account for that.

        * configure.ac: Add a test for the `restrict` keyword so that
        eventually we can use it.

        * coders/jpeg.c (ReadJPEGImage): Tidy JPEG reader by moving JPEG
        properties analysis code into subroutines.

2009-04-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * doc/display.imdoc: Fix documentation for crop and chop keyboard
        accelerators.  Fixes SourceForge bug #2593388 "error in the
        documentation/Keyboard accelarators".

2009-04-20  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/png.c: Cosmetic-only, change `True` to `MagickTrue` or
        `MagickPass` and `False` to `MagickFalse` or `MagickFail`.

2009-04-20  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/png.c: Check error return from CompressColormapTransFirst()

2009-04-20  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/png.c: Refrain from modifying image struct members
        (matte, colors, depth) while writing a PNG.

2009-04-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * doc/options.imdoc: Document the direction of rotation.

2009-04-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/log.c (LogMagickEventList): Use MagickPackageName from
        version.h rather than hard-coding `GraphicsMagick`.

2009-04-18  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/jpeg.c: Fixed a warning about `shadowed` variables.

2009-04-17  Glenn Randers-Pehrson <glennrp@simple....>

        * coders/png.c: Fixed some warnings about `shadowed` variables.

2009-04-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Add tests for some reentrant versions of functions
        where we are still using the non-rentrant versions.

        * magick/composite.c (CompositeImage): Fix problem with
        compositing images where the change image overlaps off the left
        side of the canvas.  Should fix SourceForge issue #2766200 `memory
        allocation error when compositing small images`.

2009-04-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/semaphore.c: Re-arrange ifdefs so that it is possible to
        use pthreads under the WIN32 API.

        * magick/bit_stream.c: Bitstream functions were often not inlining
        and inline functions which don't inline are not much use.
        Bitstream functions are now normal library functions.

2009-03-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * VisualMagick/bin/delegates.mgk: Remove bounding box option (-g) from
        Postscript delegate specifications.

        * config/delegates.mgk.in: Remove bounding box option (-g) from
        Postscript delegate specifications.

        * coders/{ept.c, pdf.c, ps.c} : PDF bounding box is sometimes
        incorrect or not globally applicable so don't specify bounding box
        when reading PDF files.  Postscript files do need the bounding box
        so make sure that it is still supplied.  Resolves SF tracker issue
        2487651 `convert from pdf chops off rhs`.

2009-03-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/Magick++/Image.rst: Translate Image.html to reStructuredText
        format for easier maintenance.

2009-03-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/rgb.c: Compute the quantum type rather than using a
        recurring conditional statement.  It turns out that the -endian
        option is working as it should.

2009-03-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/{gray.c, rgb.c, cymk.c}: Work toward supporting the
        -endian option.  Not working properly yet.

        * magick/enum_strings.c (EndianTypeToString): New function.
        (InterlaceTypeToString): New function.

2009-03-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * wand/drawing_wand.c: Stripped out unused code.

        * www/wand: Added formatted Wand API documentation.

        * scripts/format_c_api_doc.py: Now supports --include-rst option.

2009-03-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/image.c (GetImageBoundingBox): If we fail to find a
        smaller bounding box, then the returned bounding box is the entire
        image.

2009-02-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * VisualMagick/magick/magick_config.h.in: Provide configuration
        access to the DisableSlowOpenMP define.

        * PerlMagick/t/read.t: Add a test for HRZ Slow scan TV.

        * magick/pixel_cache.c (ModifyCache): Set image `taint` flag and
        clear monochrome and grayscale flags when pixels are accessed
        read/write rather than at sync.

        * coders/Makefile.am (MAGICK_CODER_SRCS): Add coders/hrz.c to
        build.

2009-01-27  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/hrz.c: New HRZ reader for slow scan TV.

2009-02-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/resize.c (ResizeImage): Make error handling more robust.

        * magick/pixel_cache.c (SetNexus): Return a run-time error to
        invoking code rather than exiting the program if the pixel staging
        buffer fails to be allocated.

2009-02-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/tiff.c (ReadTIFFImage): Allow the user to force the
        returned image to be TrueColor type for min-is-white and
        min-is-black TIFF files.  Previous to this, bilevel TIFF files
        were always returned as PseudoClass.

2009-01-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/pixel_cache.c, coders/pnm.c: Fix several race conditions
        reported by Julian Seward.
        (OpenCache): Restore conservative pre-allocation of pixel indexes
        since a glitch was encountered that needs to be resolved.

        * magick/{channel.c,compare.c,constitute.c,decorate.c,effect.c,fx.c,
        image.c,operator.c,pixel_iterator.c,render.c,resize.c,segment.c,
        shear.c,transform.c}: Use explicit OpenMP critical sections to
        avoid possible cross-contention.

        * coders/{dpx.c, pnm.c} Use explicit OpenMP critical sections to
        avoid possible cross-contention.

2009-01-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/pixel_cache.c (OpenCache): Remove conservative
        pre-allocation of pixel indexes.

2009-01-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * www/index.rst: Reduce the amount of text on the front page.

2009-01-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * GraphicsMagick.spec.in: The module .la files need to be
        installed as part of the base install or else the modules will
        fail to load.

2009-01-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/dib.c (ReadDIBImage): Fix assertion thrown for DIB files
        with negative image height values.

2009-01-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * coders/bmp.c (ReadBMPImage): Fix assertion thrown for BMP files
        with negative image height values.  Resolves SF issue 2523536 `bug
        in bmp coder`.

        * Makefile.am: Don't install Magick++ headers if Magick++ is
        disabled.

        * GraphicsMagick.spec.in: --enable-lzw option is no longer used.

2009-01-17  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/fits.c: More robust fits parsing.

2009-01-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * NEWS.txt: Updated news.

2009-01-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/colorspace.c (XYZTransformPackets): Fix arithmetic
        overflow problem noticed for Q32 build when using GCC on
        big-endian systems.

        * magick/constitute.c: Update Richard Nolde's float 16 and 24
        functions.

        * magick/command.c (VersionCommand): Print some build information
        for MSVC builds.

2009-01-10  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/fits.c: Ability to skip unsupported multidimensional object.

2009-01-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * magick/blob.c (GetBlobSize): It seems that under Windows, the
        zip stream is not usable as a file handle.  Switch back to using
        stat instead, but use _stati64 if available.

2009-01-04  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * coders/fits.c: Fixed bug in scene count in extension block.

        platform-specific types.

        * magick/magick_types.h.in: Include sprintf scaling strings for
        platform-specific types.

        * magick/constitute.c (WriteImage): If output stream is not
        seekable and coder needs to use seek, then divert output to
        temporary file, and then send file to stream.

        * magick/blob.c (GetBlobSize): Simplify implementation.
        (OpenBlob): Don't attempt to test header magic on file we are
        writing.  Silly benign bug in obtuse code.

        * coders/tiff.c (ReadTIFFImage,WriteTIFFImage): Strip out use of
        temporary file.  Use TIFFClientOpen() for writing.
