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.

magick/gem.c (TransformHSL): Avoid GCC opimization bug on Opteron which caused wrong results. Ensure that returned values fall within bounds 0.0 to 1.0.
(TransformHWB): Avoid GCC opimization bug on Opteron which caused wrong results. Ensure that returned values fall within bounds 0.0 to 1.0.
PerlMagick/t/ttf/read.t: Relax strictness quite a bit for TTF read tests in order to allow somewhat different FreeType output.

2004-12-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/bmp.c (WriteBMPImage): Handle the case where the image has an over-sized colormap. Was writing on unallocated heap memory.

magick/gem.c (Modulate): Hue argument now represents a rotation from -180 degrees to +180 degrees expressed as an argument of 0 to 2.0 (1.0 for no change). Note that this change also effects the -modulate argument and the Magick++ modulate method(). This change is made because the previous hue adjustment strategy only succeeded in corrupting the image.

2004-12-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/nt_base.c (opendir): Ensure that data may not overwrite the stack.

utilities/Makefile.am (check): Add convert -list tests.
magick/module.c: (InitializeModuleSearchPath): Evaluate and cache module search path.
(FindMagickModule): Use cached module search path. (OpenModules): Load all modules rather than just the modules in the directory where the LOGO module is found. Besides allowing user-provided modules in non-GraphicsMagick directories to be loaded, this allows the "moby" shared build to load additional modules via OpenModules.
GraphicsMagick.spec.in: Install *-config scripts with mode 755 rather than default 644.
magick/type.c (ReadTypeConfigureFile): Determine location of Ghostscript fonts only once in order to improve performance.
magick/nt_base.c (NTGhostscriptFonts): Properly determine Ghostscript font location for Ghostscript 8.0 and later.

2004-05-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

configure.ac: Magick++ needs to be built as a static library under Cygwin and MinGW since C++ exceptions don't work otherwise. Be more assertive about that.

utilities/Makefile.am (check): Change geometry arguments which were expressed as 0.0xVAL to avoid the problematic Linux scanf feature back to 0xVAL.

2004-04-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/utility.c (GetMagickDimension): New function to replace occurances of scanf(geometry,"%lfx%lf",&w,&h) since Linux scanf() and strtod() misbehave for strings that start with "0x". The Linux versions always treat 0x as the start of a value expressed in hex and can't be forced to read the leading value as a double. This function has been applied globally to replace the problem scanf's.

2004-04-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/version.h.in: Make it clear in the -version output that a mutitude of copyrights and licenses apply to this software.
magick/utility.c (GetPathComponent): Avoid strncpy() of overlapping regions.

utilities/gm.c (main): Default usage message wasn't right for aliased utility.
configure.ac: Added the --enable-magick-compat option to install compatibility links to emulate ImageMagick commands.
magick/command.c: Ensure that each sub-command responds to -help and -version appropriately.
utilities/gm.c (main): Invoke appropriate sub-command if gm is executed under a traditional alternate name such as "convert". The user may create hard or symbolic links from 'gm' to a traditional ImageMagick utility name (or just copy 'gm' to the desired sub-command name) in order to be 100% command-line compatible with ImageMagick 5.5.2. This is necessary in order to work with existing software designed to execute ImageMagick utilities.

2004-04-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/compress.c (Ascii85Tuple): Fix an encoding bug noticed on DEC Alpha.

2004-04-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/pdf.c (ReadPDFImage): Double-check that Ghostscript produced an output file since sometimes it reports success after it has spewed an error message and has produced no output.

version.sh (PACKAGE_VERSION): Release version 1.1. Bumped revision to 1.1.1.
magick/studio.h: Disabled use of Windows message lookups entirely since this doesn't seem to work for programs. It probably only works for DLLs like ImageMagickObject.
magick/delegate.c (ListDelegateInfo): Don't get stuck in a loop if fprintf() returns zero.

2004-04-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

VisualMagick/*/*.bat: Add .exe to exe file names in order to ensure that the executable is executed rather than something else (such as a batch script).
magick/locale.c: Only use Windows resource message lookup for the DLL build since it doesn't seem to work for static executables.
magick/utility.c (SetClientPath): Ensure that client path is null terminated.
(SetClientFilename): Initialize default client filename to "" rather than "gm.exe" and ensure that filename is null terminated. (SetClientName): Ensure that client path is null terminated.
magick/blob.c (GetConfigureBlob): Enable logging the load of log.mgk
magick/log.c: Re-designed logging initialization in order to avoid the "chicken and the egg" snafu. This allows logging the initialization of the logging subsystem.

2004-04-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

VisualMagick/bin/log.mgk: Add comments to help document usage.
config/log.mgk: Add comments to help document usage.
magick/utility.c (IsAccessible): Use access() rather than stat(). (IsAccessibleNoLogging): Use access() rather than stat(). (IsDirectory): Implemented return status according to existing API documentation.

magick/fx.c (ConvolveImage): Support convolution in CMYK colorspace.

2004-03-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

version.sh (PACKAGE_CHANGE_DATE): Update release to 1.1Beta2.
magick/constitute.c (ReadImage): Ignore errors of type ConfigureError when loading modules so that error report can still report the familiar "No delegate for this image format" message while still being able to report problems with loading a module if it was found. This is a compromise which reports useless messages when the modules are not found at all, but I can't think of a way around it.
magick/nt_base.c (NTSystemComman): Adjust MsgWaitForMultipleObjects() arguments to wait for object to be signaled only (FALSE) rather wait for object to be signaled as well as an input event received(TRUE). It seems that process status changes do not result in an input event, so the call was deadlocking.
magick/constitute.c (ReadImage): If module loading reported an error, ReadImage immediately returned an error rather than trying to use a delegate defined by delegates.mgk.

2004-03-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

version.sh: Updated version to 1.1Beta1

2004-03-24 Mike Chiarappa <mikechiarappa@libero.it>

coders/plasma.c (ReadPlasmaImage): srand() is already invoked by InitializeMagick() so don't call it here.
configure.ac: Check for rand_r().
magick/tempfile.c (ComposeTemporaryFileName): The full range of safe characters was not being used, thereby limiting the number of unique temporary file names available.

2004-03-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/image.c (GetImageStatistics): New function to obtain image statistics (minimum, maximum, mean, variance, and standard deviation).
(DescribeImage): Include image channel statistics in verbose output.

2004-03-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/constitute.c (DispatchImage): Removed some unreachable code that was accidentially left in the switch statement.
magick/pixel_iterator.c (PixelIterateDualRead): Extended so that the region in each image may use a different origin. (PixelIterateDualModify): Extended so that the region in each image may use a different origin.
magick/composite.c (CompositeImage): Fix XorCompositeOp overflow condition which occured on non-Intel architectures.

2004-03-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/constitute.c (DispatchImage): Be more careful when rounding pixel intensity.
(ConstituteImage): Be more careful when converting float and double to Quantum.
magick/composite.c (CompositeImage): Fix Multiply composite operator for Q:32 build (was all black image). (CompositeImage): Tidied up the documented composite operators so the implementation is easier to understand.
PerlMagick/t/ttf/read.t: Set a desired label size so output image should be the same size as the reference image even if the FreeType type hinter is disabled.
magick/annotate.c (RenderFreetype): Improve outline bounding box computation accuracy.

2004-03-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2004-03-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/Makefile.am: Removed some apparently unnecessary library dependencies.
Makefile.am (windows-src): Added a way to generate a Windows source zip file.

2004-03-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/command.c: The -operator command now supports floating-point and percent of range arguments.

2004-03-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/command.c: Added support for -operator command with syntax "-operator channel operator rvalue" which applies a arithmetic or bitwise operator to a specified image channel or all channels.

2004-03-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

PerlMagick/t/filter.t: Fix Solarize test case.

2004-03-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/jpeg.c (WriteJPEGImage): If image_info->colorspace is set to GRAYColorspace then make sure that image is in a gray colorspace.
magick/image.c (TransformRGBImage): If colorspace is already an RGB type (RGBColorspace, GRAYColorspace, or TransparentColorspace), then simply return. Do *not* set image->colorspace to RGBColorspace since this potentially loses a valuable setting.

2004-03-10 Peter Boos <pedib@colorfullife.com>

magick/annotate.c (RenderFreetype): If DrawAnnotation is called with a string containing only one character and this character is not recognized by the TrueType engine, a crash occured due to the failure of FT_Load_Glyph. The failure caused an uninitialized glyph.image pointer to be used by FT_Done_Glyph() later in the code. The solution is to initialize the glyph.image pointer to null.

2004-03-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/image.c (QuantumOperatorRegionImage): Properly handle over and underflow of arithmetic operators.
magick/draw.c (DrawGetFillOpacity): Use fill opacity, and invert opacity range so it is 0.0 to 1.0 (was acting like transparency). (DrawSetStrokeOpacity): Validate range of stroke_opacity. (DrawSetFillOpacity): Save value to context->fill.opacity and validate the range of fill_opacity.
magick/image.c (QuantumOperatorImage): New function to apply an arithmetic or bitwise operator to the pixel quantums in an image. (QuantumOperatorRegionImage): New function to apply an arithmetic or bitwise operator to the pixel quantums in an image region.
magick/image.c (IsImagesEqual): Re-implemented using the new pixel iteration functions as a proof of concept.
magick/pixel_iterator.h: Added some pixel iteration functions in order to make it easier to implement algorithms which only need to iteratively access pixels in a region. These functions are not part of the API yet so their interface should be considered unstable.
doc/GNUmakefile: Rename Makefile to GNUmakefile since it relies on GNU make extensions.

2004-03-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/constitute.c (ConstituteImage): Add support for 'T' (transparency) and 'O' (opacity) map types. Simplify implementation.
(DispatchImage): Add support for 'T' (transparency) and 'O' (opacity) map types. Simplify implementation.
config/delegates.mgk.in: Quote delegate command names so that they can contain embedded spaces.
VisualMagick/bin/delegates.mgk: Quote delegate command names so that they can contain embedded spaces.
coders/tiff.c (WriteTIFFImage): Use the libtiff default endian mode when writing TIFF rather than forcing MSB2LSB bit order. (ReadTIFFImage): Enable reading in MSB2LSB bit order (better for our byte-level parsing), enable memory mapping, and enable strip chopping. Memory mapping and strip chopping are probably enabled by default.
magick/nt_base.c (NTSystemComman): Use MsgWaitForMultipleObjects() rather than WaitForSingleObject() in order to avoid possible deadlock when application code directly or indirectly creates windows.

2004-02-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/animate.c (XMagickCommand): URL should point to http://graphicsmagick.org/.
magick/display.c (XMagickCommand): URL should point to http://graphicsmagick.org/.

2004-02-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/animate.c (XAnimateImages): Memory leak reduction and better integration with gm command.
magick/display.c (XDisplayImage): Display was leaking memory like a sieve. Now it doesn't.
magick/memory.c (CloneMemory): Computation for when it is safe to use memcpy() was incorrect. Use memmove() rather than backwards-copy loop.
Makefile.am ($(DIST_ARCHIVE_SRPM)): Added rules to build a source RPM.
configure.ac: Search for 'buildrpm' or 'rpm' programs in order to support creating RPM packages on a system which has RPM installed.
version.sh (PACKAGE_VERSION): Changed snapshot release naming so that there is only one dash in the name and the snapshot date is prefixed with '0' to assure proper directory sorting. This allows snapshot naming to be acceptable to RPM. The snapshot package name is now similar to GraphicsMagick-1.1.020040218.tar.bz2

2004-02-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/xwd.c (RegisterXWDImage): Always register XWD, but only register read/write methods if it is supported.

(VerticalFilter): do process K channel for CMYK images.

2004-02-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/tga.c (ReadTGAImage): Fix matte channel handling. For 16-bit packets, use integer rather than floating point. Return gray images as PseudoClass and set is_grayscale flag. Add logging.
magick/fx.c (WaveImage): Ensure that image is DirectClass. Ensure that matte channel is initialized if necessary. Include background color in is_grayscale evaluation.
magick/gem.c (GenerateNoise): Scale noise to range of quantum.

2004-02-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/constitute.c (MapQuantumType): Fix spurious comma in enum definition.
magick/blob.c (GetBlobStreamHandler): Apparently return type can not be const.

2004-02-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

configure.ac: Check for Windows fonts under /usr/X11R6/lib/X11/fonts/truetype (XFree86 standard location?).
coders/jp2.c (WriteJP2Image): Support providing a compression rate value (range 0.0 to 1.0) using command line syntax similar to '-define jp2:rate=0.5'. In Magick++ this option may be accessed similar to image.defineValue("jp2","rate","0.5");
magick/command.c (DisplayImageCommand): Exit status was inverted so 'gm display' was returning 1 for successful commands, and 0 for failures.
(AnimateImageCommand): Exit status was inverted so 'gm animate' was returning 1 for successful commands, and 0 for failures.

2004-02-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/utility.h (MagickReallocMemory): Solaris compiler complains about cast so remove it.

2004-02-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/png.c (UnregisterPNGImage): Destroy PNG semaphore.
magick/image.c (SetImageInfo): Since we don't know what the "IMPLICIT" specifier is supposed to do, support for it is removed. Perhaps by removing support for it, we will be reminded why it exists.
magick/magick.c (DestroyMagickInfo): Invoke UnregisterStaticModules().
(GetMagickInfo): Remove registration for "IMPLICIT" format since its purpose is presumed bogus.
magick/static.c (UnregisterStaticModules): New function so we can unregister static modules.
coders/plasma.c (UnregisterPLASMAImage): Unregister FRACTAL.
coders/icon.c (UnregisterICONImage): Unregister CUR.
coders/bmp.c (UnregisterBMPImage): Unregister BMP2 and BMP3.
coders/meta.c (UnregisterMETAImage): Unregister APP1JPEG, IPTC, IPTCTEXT, IPTCWTEXT, and PICON.
coders/miff.c: Check for run-length termination before testing memory and only check opacity channel if matte is valid.
magick/compress.c: Check for run-length termination before testing memory (bad read error).

2004-02-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/tiff.c (WriteTIFFImage): Fix detection of when to use a temporary file when writing TIFF. Writing to TIFF BLOBs was broken by the recent changes to make BlobInfo a private type.
magick/render.c (DestroyEdge): Use memmove for overlapping copy.

2004-02-03 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

coders/wpg.c (ExtractPostscript): Use DestroyBlob.
magick/blob.c (DestroyBlob): New function. Similar to DestroyBlobInfo except that it requires an Image * argument and zeros the blob pointer. This one is preferred for use over DestroyBlobInfo.

2004-01-27 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

coders/png.c: Add DestroyBlobInfo() calls to stop memory leak when processing JNG datastreams.

2004-01-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/utility.h (MagickReallocMemory): Added a cast required to make C++ Happy.
coders/tiff.c: Adjust for bitstream API function renaming.
magick/bit_stream.h: Rename BitStreamRead() to BitStreamMSBRead() to indicate that it reads most significant bytes first ("big endian" order). Rename BitStreamWrite() to BitStreamMSBWrite() to indicate that it writes most significant bytes first ("big endian" order).
wand/magick_wand.c: Updated to lastest ImageMagick API.

2004-01-26 Mike Chiarappa <mikechiarappa@libero.it>

magick/stream.c: (SetPixelStream) removed "const" from definition of local variable [StreamHandler stream]. Borland C++Builder compiler signal error "Cannot modify a const object".

2004-01-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/tiff.c (TIFFMapBlob): Allow libtiff to access memory mapped file (or BLOB in memory) directly. This provides a small performance increase.
magick/constitute.c (ReadImage): If a .mpc file is a temporary file, then be sure to remove the associated .cache file when removing the .mpc file.
magick/log.h (LogEventType): ExceptionEventMask now maps to WarningEventMask|ErrorEventMask|FatalErrorEventMask so that '-debug exception' works again.
magick/blob.c (CloseBlob): Allow CloseBlob to be invoked on a blob which is not open (in UndefinedStream state). (BlobInfo): The definition of BlobInfo is now private to blob.c. (StreamType): The StreamType enumeration is now private to blob.c. (GetBlobFileHandle): New function to access the blob file handle. (GetBlobStreamHandler): New function to access the blob stream handler.
(GetBlobStreamType): This function is removed entirely. (BlobIsSeekable): New function to test if SeekBlob will work properly for this blob type.
(GetBlobClosable): New function to test if the blob is allowed to be closed by the library (may be an externally provided file descriptor).
(GetBlobTemporary): New function to test if input file is a temporary file which is to be removed. (SetBlobClosable): New function to support setting the flag which keeps the input file from being closed. (SetBlobTemporary): New function to support setting the flag which indicates that the input file is a temporary file.
coders/jpeg.c (ReadJPEGImage): Invoke CloseBlob even if blob is in UndefinedStream state.
magick/error.h (ThrowReaderException): Ditto. (ThrowWriterException): Ditto.
(ThrowWriterException2): Ditto. (ThrowWriterException3): Ditto.

coders/dps.c,coders/jpeg.c, coders/meta.c, coders/mvg.c, coders/png.c, coders/tiff.c, magick/constitute.c, magick/stream.c: Use new blob accessor functions.
magick/cache.c (OpenCache): For Windows, set the sequential access flag in all cases. Maybe it will make a difference.

2004-01-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/blob.c (GetConfigureBlob): Don't check Windows registry if MagickLibConfigPath or MagickShareConfigPath is defined.

magick/nt_base.c (mmap): Re-wrote mmap emulation to support 64-bit file offsets and to support anonymous mapping. (msync): A crude emulation of Unix msync().
acinclude.m4 (GM_FUNC_MMAP_FILEIO): Change result define from HAVE_MMAP to HAVE_MMAP_FILEIO so that it doesn't conflict with Autoconf standard definition.

2004-01-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/cache.c (OpenCache): While allocating the pixel cache from the heap, reserve enough memory to contain a full PseudoClass image in order to reduce the chance that there will be a memory allocation failure while processing the image. This also avoids the possibility that the image pixels will be block-copied to a new location due to heap memory fragmentation. If there is insufficient heap memory (malloc() fails), then a disk-based pixel cache will be used.
coders/wpg.c: Backed out Jaroslav Fojtik's patch from 2004-01-13 because WPG was failing PerlMagick's existing WPG read test.

2004-01-16 Mike Chiarappa <mikechiarappa@libero.it>

Makefile.am (DISTDIRS): Distribute TclMagick subdirectory.

2004-01-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

wand/magick_wand.c: Ported over the latest ImageMagick Wand API updates. Note that a comment now says that the Wand API will not be finished until around 4th quarter of 2004. This represents a 1-1/2 year slip from the original estimate!

2004-01-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/image.c (IsImagesEqual): Simplified implementation.
magick/magick.c: Removed some unused code.
contrib/win32/ATL7/ImageMagickObject/ImageMagickObject.cpp (IDispatch): Comment out InitializeSemaphore() so code compiles.

2004-01-03 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

coders/sgi.c: opacity channel was lost when writing grayscale SGI images. See bug report in magick-users list.

2003-12-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/annotate.c (RenderFreetype): Ensure that image storage class is set to DirectClass. Text rendering was not working properly on top of PseudoClass images.
magick/map.c (MagickMapRemoveEntry): Logic didn't properly handle removing entry in list.
configure.ac: Added --enable-efence option to enable memory debugging using Electric Fence.

2003-12-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

tests/maptest.c (main): Extended test to add an entry to the list after an entry has already been removed.
magick/image.c (ColorspaceTypeToString): Add support for LAB colorspace.
magick/map.c: Added signature members to all structures and added assertions to ensure that the signature == MagickSignature prior to use. MagickMapAllocateObject now initializes the object reference count to one, and MagickMapDestroyObject decrements it in order to be more correct even though the object reference count is not actually used yet.
(MagickMapCopyString): Preserve a null argument, and use AcquireString since it doesn't enlarge the string storage. (MagickMapCopyBlob): Preserve null blobs.
configure.ac: Search for the shmctl() function. Under current Cygwin, this is hiding in -lcygipc.

2003-12-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/composite.c: Fixed the composite operator list in the CompositeImage documentation.
www/api/types.html: Corrected list of composition operators. Sometime prior to the creation of GraphicsMagick, the "Replace" composite operators were renamed to be "Copy" composite operators. Thanks to David Relson for bringing this problem to our attention.
PerlMagick/Magick.xs: Added "LAB" to colorspace types.
magick/image.h (enum ColorSpace): Add LABColorspace enumeration.
wand/magick_wand.h : Add some compatibility definitions to translate from ImageMagick enumerations to existing GraphicsMagick enumerations.

2003-12-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/annotate.c: Use header synonyms defined by FreeType's ftheader.h (included via <ft2build.h>) to include FreeType headers. This will presumably be more portable in the future.
configure.ac: <ft2build.h> is an optional prerequisite for <freetype/freetype.h> and <libwmf/ipa.h> so include it when testing for these headers.
magick/annotate.c: Include <ft2build.h> if it is available.

2003-12-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

wand/wandtest.c: Ported from latest ImageMagick version.
wand/drawing_wand.c: Adapted to be compatible with latest ImageMagick version.

wand/magick_wand.c: Ported from latest ImageMagick version.
magick/image.h (Image): Members color_profile, iptc_profile, generic_profile, and generic_profiles are now deprecated and private although they continue to work as before. Please migrate existing code to use the GetImageProfile and SetImageProfile functions since these members will eventually be removed.
magick/image.c (GetImageProfile): New function to retrieve an image profile. Return value differs from similarly named ImageMagick method since the ImageMagick approach assumes a particular storage method.
(SetImageProfile): New function to add (or remove) an image profile. Does not execute CMS color profiles.
magick/cache.c (SetImageVirtualPixelMethod): Return unsigned int to make the Wand implementation happy.
magick/image.c (TransformColorspace): Return unsigned int to make the Wand implementation happy. (SetImageType): Return unsigned int to make the Wand implementation happy.
magick/draw.h, magick/draw.c: Substitute 'unsigned long' in place of 'size_t' in interfaces so that the draw API is not sensitive to the definition of _LP64.
locale/C.mgk: Added new messages required by Wand library.
magick/error.c (ExceptionSeverityToTag): Add tag translations for the WandWarning, WandError, & WandFatalError enumerations
magick/error.h (enum ExceptionType): Add WandWarning, WandError, & WandFatalError enumerations to ExceptionType for ImageMagick API compatibility.
magick/image.h (enum ChannelType): Add an 'AllChannels' enumeration to the ChannelType enumeration for ImageMagick API compatibility.

2003-12-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

PerlMagick, tests: Adjusted allowed error values for tests based on new error computation arithmatic. Some tests were left failing since the operation they test provides results which are unreasonably inaccurate, or obviously broken.

2003-12-17 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

coders/jpeg.c: Changed "JPEG:preserve-settings from a key/value pair to a simple flag. Save and restore attributes when "-define JPEG:preserve-settings" appears on the commandline. Use "+define JPEG:preserve-settings" to unset the flag.

2003-12-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/wmf.c: Include <ft2build.h> if it is available since some libwmf installs don't work unless it is included before the libwmf API headers.
configure.ac: Check for <ft2build.h>.

2003-12-16 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

coders/jpeg.c: Changed stored jpeg quality attribute from [jpeg-quality] to JPEG-Quality. Added attributes JPEG-Colorspace and JPEG-Sampling-factors. Added code to save and restore these attributes when "-define JPEG:preserve-settings=yes" is present in the comandline. Quality is restored if the input was a JPEG and the quality was preserved. Sampling factors are restored if the input was a JPEG, sampling factors were preserved, and the colorspace for the output file is the same as that of the input file.

2003-12-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

TclMagick/source/configure.ac: Add an initial TclMagick configure-based build environment based on a template and macros from the Tcl project. I recall that while the extension does build, it is possible that it is not properly registered as a module to Tcl.

2003-12-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/image.c (IsImagesEqual): Properly compute error distance vectors. Math was missing the necessary sqrt call. Also, pre-normalize the error differences to 1.0 in order to reduce the storage size required to store the summation of error values.
PerlMagick/t/composite.t: Update Minus and Xor reference images.
magick/composite.c (CompositeImage): Incorporated fixes from ImageMagick for XorCompositeOp, PlusCompositeOp, and MinusCompositeOp. Thanks to John Cristy for bringing the need for these fixes to our attention.
magick/image.h (RoundToQuantum): Added missing parenthesis.

2003-12-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

doc/environment.imdoc: Document MAGICK_CODER_MODULE_PATH and MAGICK_FILTER_MODULE_PATH.
rungm.sh.in: Pass MAGICK_CODER_MODULE_PATH and MAGICK_FILTER_MODULE_PATH in the environment so modules build may be tested without first being installed.
magick/module.c (FindMagickModule): Use the MAGICK_CODER_MODULE_PATH environment variable to specify a search path for coder modules. Use MAGICK_FILTER_MODULE_PATH to specify a search path for filter modules.
Makefile.am: Updated to Automake 1.8. (install-exec-perl): Fixes which achieve a successful 'make distcheck' for the first time in *Magick history.
configure.ac: Set scripts to executable.

2003-12-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

Makefile.am (uninstall-data-html): Pathnames were computed incorrectly so documentation directories were being left behind.
configure.ac: --without-frozenpaths is now the default. This helps 'make distcheck' work and makes the package more portable. Path to gm was being incorrectly frozen when --without-frozenpaths was specified.
magick/delegate.c (ReadConfigureFile): Validate delegate paths prior to substitution.
rungm.sh.in (top_builddir): Use a more reliable scheme for computing location of source and build directories.
magick/Makefile.am: Improve include directory computation logic.
configure.ac: Don't override includedir. Pass user-supplied LIBS to the linker.

2003-12-08 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

coders/jpeg.c: store JPEG quality as "[jpeg_quality]" attribute.

2003-12-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

rungm.sh.in: New script to support executing uninstalled executables.
magick/blob.c (GetConfigureBlob): New MAGICK_CONFIGURE_PATH environment variable allows the user to specify the search path for configuration (.mgk) files.

2003-12-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

index.html: Added a table showing current stable release and development version.

2003-12-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

doc/options.imdoc (use): Describe the syntax of the -process argument.
acinclude.m4 (AC_CHECK_CC_OPT): Add quoting in AC_CHECK_CC_OPT definition. Change suggested by Patrick Welche

2003-12-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/magick.c (GetMagickInfo): Fix preprocessing logic error which caused moby shared library build to not register static modules.

2003-12-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/module.c (ExecuteModuleProcess): Add some logging.
magick/static.c (ExecuteStaticModuleProcess): Add some logging.

2003-11-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

VisualMagick/installer: Add optional build support for LZW.
wand/Makefile.am: Add AUTOMAKE_OPTIONS.
configure.ac: Update to Autoconf 2.59.

2003-11-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

VisualMagick/installer/inc/tasks-install-perlmagick.isx: Update to reflect that the next release will use ActivePerl 5.8.1 Build 807.
VisualMagick/installer/inc/files-configs.isx: Updated the source locations for the .mgk files. Install modules.mgk into the config directory rather than the modules directory.
configure.ac: Fixes to work with latest CVS libtool.
libtool.m4: Update to latest CVS libtool.
magick/modules.c, magick/static.c (ExecuteStaticModuleProcess): Fix conditional compilation logic so that "moby" shared library build works again.
magick/compress.c, magick/mac.c: Use existing SaveImageText and LoadImageText global constants rather than separate defines.

2003-11-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

configure.ac: Update to Autoconf 2.58.
Makefile.am: Update to Automake 1.7.9.

2003-11-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/draw.c (DrawComposite): Base64-encoded image was not being deallocated. Bad memory leak.

2003-11-03 Mike Chiarappa <mikechiarappa@libero.it>

BCBMagick: Updated installation procedure. Please read BCBMagick/readme.txt for details.

2003-11-03 Mike Chiarappa <mikechiarappa@libero.it>

BCBMagick: Released DLL Version. Please read BCBMagick/readme.txt for details about installation and/or use.

2003-11-03 Lars Ruben Skyum <lars.skyum@stibo.com>

magick/utility.c (GetPathComponent): Added x, X, and + characters to list of legal characters in subimage specifications. Required by raw RGB image reader which accepts the syntax "image.rgb[100x100+50+50]". Thanks to John Cristy for catching that one.

2003-11-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/locale.c (GetLocaleMessageFromID): Fix ID range checking logic.

2003-10-30 Lars Ruben Skyum <lars.skyum@stibo.com>

coders/jpeg.c: changed to not write gray CMYK images as grayscales. That would not be a valid optimization.
magick/color.c (IsGrayImage, IsMonochromeImage): Changed to never return true for CMYK images. Separated images get wrong colors when optimized to grayscales based on what these two functions return. Gray and CMYK are two different color spaces.
magick/nt_feature.c (NTIsMagickConflict): changed to accept colon as part of the magick string, consistent with the way the function is used.
magick/utility.c, magick/utility.h (ExpandFilenames, GetPathComponent): Fixed filename glob expansion. Added handling of filename prefix-magick and sub-image specification to GetPathComponent. Sub-image specification takes precedence over any filename patterns.

2003-10-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/static.c (ExecuteModuleProcess): Renamed from ExecuteStaticModuleProcess. Only compiled if SupportMagickModules is not defined.
magick/type.c (GetTypeBlob): Eliminated function. (ReadTypeConfigureFile): Use GetConfigureBlob() rather than GetTypeBlob().
magick/module.c (GetModuleBlob): Eliminate this function since modules.mgk is now installed under ${prefix}/share/GraphicsMagick-version/config so GetConfigureBlob() may be used. (lt_dlexit, etc.) Eliminate fake libltdl function wrappers used for the static build.
(DestroyMagickModules): Added a new destroy function (simply invokes DestroyModuleInfo()).
(GetModuleList): Learn where modules live by using FindMagickModule() to locate the LOGO module rather than by using the location of modules.mgk. This is necessary since now modules.mgk may be seperate from the modules. (GetModuleBlob): Eliminated function. (InitializeMagickModules): New function to safely initialize the module loader.
(OpenModule): Added logging messages. (OpenModules): Added logging messages. (ReadModuleConfigureFile): Use GetConfigureBlob() rather than GetModuleBlob().
Totally eliminated the rat's-nest of conditional code dependent on SupportMagickModules. Now all the code in module.c is dependent on #if defined(SupportMagickModules).
magick/magick.c (DestroyMagick): Invoke DestroyMagickModules(). (GetMagickInfo): #ifdef chunks of code which exist to support the modules-build rather than forcing the module loader to pretend that modules are being used when they are not. Pass module loading exceptions back to the user rather than discarding them. (GetMagickInfoArray): Don't inspect the exception status since may short-circuits the operation. Use best-effort instead. (ListMagickInfo): Don't inspect the current exception status so that all the modules which did load successfully will be represented.
(InitializeMagick): Invoke InitializeMagickModules().
magick/log.c: (GetLogBlob): Eliminated function. GetConfigureBlob() is safe to use now when configuring logging. (LogToBlob): Simplified function. Only exists since FileToBlob() may throw exceptions (which are logged, causing deadlock). (ReadLogConfigureFile): Use GetConfigureBlob().
magick/blob.c (GetConfigureBlob): Re-written to use the MagickMap interface and to support the new 'lib' and 'share' config directories. The directory ${prefix}/lib/GraphicsMagick-version/config is scanned before ${prefix}/share/GraphicsMagick-version/config. (FileToBlob): Simplified implementation.
config/Makefile.am: New makefile to install .mgk files.
magick/magick_config.h.in: Added MagickLibConfigPath and MagickShareConfigPath defines.
configure.ac: Install configuration files (.mgk files) in ${prefix}/lib/GraphicsMagick-version/config and ${prefix}/share/GraphicsMagick-version/config. Architecture independent files to under "share" while architecture dependnet files go under "lib".
Makefile.am: Added 'config' subdirectory to distribution. All .mgk files are moved from 'coders' & 'magick' into this single directory.

2003-10-21 Mike Chiarappa <mikechiarappa@libero.it>

magick/studio.h: small modifications to achieve DLL compilation of library with Borland C++ Builder.
coders/ps3.c (ZLIBEncode2Image): Fixed bug. Compilation fail when HasZLIB is undefined because parameters 5 and 6, are undefined.

2003-10-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

libtool.m4: Updated libtool again to CVS latest version. Libtool required some fixes for building DLLs under MinGW.
magick/resource.c (InitializeMagickResources): Some code is conditional based on HAVE_POPEN.
magick/utility.c (SystemCommand): Improved conditional compilation logic.
magick/blob.c (OpenBlob): Code depending on popen() is conditionally compiled based on HAVE_POPEN. Code depending on pclose() is conditionally compiled based on HAVE_PCLOSE.
configure.ac: Add test for _pclose(), pclose(), _popen(), and popen().
magick/locale.c (GetLocaleMessage): Add missing MagickExport. (GetLocaleMessageFromID): Add missing MagickExport.
VisualMagick/installer/inc/files-development.isx (Source): Include all of the headers from the magick directory in the development package. Including them individually is too error prone.

2003-10-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

VisualMagick/magick/magick_config.h.in: Added PREFIX_MAGICK_SYMBOLS as a configuration option.
magick/module.c (_CoderInfo): Added register_function and unregister_function members to record the module's register and unregister function addresses.
(OpenModule): Locate the module's register and unregister functions and save their address to the module's CoderInfo record. (UnloadModule): Invoke the module unregister function using the address recorded by OpenModule(). (TagToFunctionName): If PREFIX_MAGICK_SYMBOLS is defined, then add a "Gm" prefix to the register and unregister function names.
libtool: Updated libtool files to the latest CVS version.
configure.ac: Changed define name from MAGICK_SYMBOL_PREFIX to PREFIX_MAGICK_SYMBOLS since support is not available for specifying an arbitrary prefix.

2003-10-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

configure.ac: Added --enable-symbol-prefix configure option which prepends "Gm" to all GraphicsMagick library symbols using the C pre-processor. In the future, this may change to support specifying an arbitrary prefix, depending on experience.
magick/studio.h: Include magick/symbols.h.
magick/api.h: Include magick/symbols.h.
magick/symbols.h: New header to support optionally remapping library symbols. If MAGICK_SYMBOL_PREFIX is defined, then library symbols are remapped.

2003-10-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/api.h: Removed inclusion of <magick/semaphore.h> since it is an implementation header.

2003-10-13 Lars Skyum <lrs@stibo.dk>

www/GraphicsMagick.html, www/animate.html, www/composite.html, www/conjure.html, www/convert.html, www/display.html, www/gm.html, www/identify.html, www/import.html, www/mogrify.html, www/montage.html: added documentation for "-define" command line option.
doc/brief_options.imdoc, doc/options.imdoc: Added documentation for "-define" command line option.
doc/gmdocselect, doc/imdocselect: Changed "skipform" label in sed scripts to just "skipf". Solaris sed had problems with the long(?) "skipform" label.

2003-10-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

doc/composite.imdoc, doc/options.imdoc, doc/GraphicsMagick.imdoc: Attempted to clarify the meaning of the compose arguments and how composition works, as well as eliminating use of hard-coded values like 255.
www/links.html: Added a link to Michael Still's article "Graphics from the command line".

2003-10-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/*.c: Updated module descriptions so that they accurately describe the module rather than saying "Read/Write GraphicsMagick Image Format".
coders/cineon.c: Fix source module description. Contrary to opinion, ImageMagick did not invent the Cineon X image format so description is now "Read/Write Cineon X Image Format."
magick/magic.mgk: Added a CINEON entry for the Cineon X image format.
magick/static.c (RegisterStaticModules): Invoke RegisterCINEONImage().
coders/modules.mgk: Map "CIN" magick to CINEON module.

2003-10-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

locale/C.mgk: Added message for "UnrecognizedCommand".
magick/command.c (MagickCommand): No error was reported when a subcommand failed to be matched so 'gm foo' would silently return. Now an error message is properly reported.

2003-10-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

Makefile.am: Updated to Automake 1.7.8.
various: Edits to eliminate minor issues detected by SGI C compiler.
coders/ps3.c (WritePS3Image): Variable 'value was set but never used so it is removed.
magick/image.c (RGBTransformPacket): Removed inline request since this function is too big to inline.
magick/animate.c (XAnimateBackgroundImage): Fixed a GCC 3.X "type pinning" warning.
magick/display.c (XDisplayBackgroundImage): Fixed a GCC 3.X "type pinning" warning.
magick/render.c (GetPixelOpacity): Removed inline directive. No one in their right mind could ever imagine this function inlining successfully.
magick/cache.c (IsNexusInCore): Adjusted so function inlines as requested.
coders/tiff.c (ReadTIFFImage): Improved logging information. (WriteTIFFImage): Changed the way the bilevel/grayscale logic works. Now bilevel images are treated similar to any other grayscale image unless CCITT FAX3 or FAX4 compression is requested (which selects the MINISWHITE photometric). The default is now to write uncompressed bilevel images with MINISBLACK photometric.
PerlMagick/t/composite.t: Use some reasonable error values.
magick/image.c (GetImageDepth): Added special cases for colormapped images and monochrome images in order to improve performance.

2003-10-09 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

NEWS: added info about color scaling, sampling-factor, and changed a reference to "-coder-options" to "-define".

2003-10-09 Lars Ruben Skyum <lars.skyum@stibo.com>

VisualMagick/bin/modules.mgk: added EPS3 mapping to PS3 module.
coders/ps3.c, coders/tiff.c, magick/command.c, magick/image.c, magick/image.h, magick/utility.c: Changed -coder-options option to -define. Also renamed functions {Add,Remove,Access}CoderOption(s) to {Add,Remove,Access}Definition(s). Changed ps coder-specific option ps:image=imagemask to just ps:imagemask.

2003-10-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/cineon.c: Imported and adapted Cineon image format coder written by Kelly Bergougnoux <three3@users.sourceforge.net> with assistance from John Cristy.

2003-10-08 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

coders/jpeg.c: Extended -sampling-factor option to allow user to supply full set of sampling factors. If the full set is not supplied, omitted ones are 1x1 by default, similar to the behavior of "cjpeg -sample".
magick/command.c: Accept multiple pairs of sampling factors.

2003-10-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/tiff.c (WriteTIFFImage): Re-arranged logging for improved output. Cleaned up evaluation of SAMPLESPERPIXEL and BITSPERSAMPLE. Provided support for the TIFF coder options tiff:samples-per-pixel and tiff:bits-per-sample for power users. (ReadTIFFImage): Colormap generation for PHOTOMETRIC_MINISBLACK and PHOTOMETRIC_MINISWHITE was inaccurate. Seems to be accurate now.
PerlMagick/t/reference/read/input.miff: Updated due to Glenn's change to scale macros.
PerlMagick/t/tiff/input_gray_12bit.tiff: Replaced 12 bit image with a different one which is written by GraphicsMagick.
coders/ps3.c (WritePS3Image): Use AccessCoderOption().
magick/image.c (AccessCoderOption): Added a function to use for accessing coder-specific options.

2003-10-08 Lars Ruben Skyum <lars.skyum@stibo.com>

magick/attribute.c (TraceSVGClippingPath): optimized for speed and precision in clipping mask generation by using lines to connect Bezier curve anchor points where applicable.

2003-10-07 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

Revised ScaleColor5to8 and ScaleColor6to8 macros again, to fill the low bits correctly.

2003-10-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

PerlMagick/t/tiff/read.t: Added 16-color and 256 color colormapped tests with a matte channel.
PerlMagick/t/tiff/write.t: Added 16-color and 256 color colormapped tests with a matte channel.
coders/tiff.c (WriteTIFFImage): When using LZW compression, apply the horizontal differencing predictor to RGB truecolor and deep gray images since the TIFF spec says that LZW compression is usually improved by using horizontal differencing with continuous tone images.
Re-implemented grayscale and colormapped scanline preparation to use the new bit-stream interface. This is a bit slower, but very flexible, and the implementation is very compact. Writing of a matte (transparency) channel is now believed to be correct for all depths.
magick/command.c (MogrifyImage): Only transform the colorspace if it has been set (i.e. is not UndefinedColorspace).

2003-10-06 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

coders/png.c (ReadOnePNGImage): PNG decoder would exit too early when reading image.png[0].

2003-10-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

PerlMagick/t/tiff/write.t: Added TIFF write tests for 4 bits-per-sample TIFF images, both with and without a transparency channel.
magick/image.c (DescribeImage): Added -verbose support for displaying individual channel depths.

2003-10-06 Lars Ruben Skyum <lars.skyum@stibo.com>

magick/image.c (SetImageInfo): cleaned up parsing of subimage specification (image.psd[0]). It would fail sometimes due to incorrect reuse of variables. It's a bit strange the code accepts more range syntax-variations than can be stored in ImageInfo.

2003-10-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/image.c (ChannelImage): The OpacityChannel, MatteChannel, and BlackChannel operations set the matte channel to opaque, so set image->matte to False for those operations. (RGBTransformImage): Add an assertion to prevent passing the colorspace argument 'UndefinedColorspace'. (TransformRGBImage): Add an assertion to prevent passing an image with colorspace set to 'UndefinedColorspace'.

2003-10-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/log.c (LogToBlob): Since MagickSeek(file,0,SEEK_END) is used to obtain the Blob size, MagickSeek(file,0,SEEK_SET) must be used to restore the seek position. Thanks to John Cristy for bringing this to our attention.

2003-10-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

magick/bit_stream.h: Added a bit-stream writer function.
PerlMagick/t/reference/read/input_tim.miff: Reference image was defective.

2003-10-03 Lars Ruben Skyum <lars.skyum@stibo.com>

magick/image.c, magick/image.h: Updated AddCoderOptions to accept "flag" keys that have no values. They are placed in the coder options map with an empty, zero length string value. Option argument syntax is now: "key1[=[value1]],key2[=[value2]],..."

2003-10-03 Lars Ruben Skyum <lars.skyum@stibo.com>

magick/command.c: Updated +coder-options option to not clear the entire map of coder options, but accept a list of names to remove from the map. Use option argument "*" to clear the entire map of coder options.
magick/image.c, magick/image.h: Added function RemoveCoderOptions. Added cast of signed char to unsigned char and int in calls to isspace and isprint.
magick/utility.c: Added cast of signed char to unsigned char and int in calls to isspace and isprint. Added special handling of +coder-options option in ExpandFilenames function.

2003-10-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

PerlMagick/t/reference/read/input_tim.miff: The TIM read results changed somewhat due to Glenn's ScaleColor5to8 fix.

2003-10-01 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

Revised ScaleColor5to8 and ScaleColor6to8 macros to fill in the low bytes.
coders/bmp.c (ReadBMPImage): scaling of 8-8-8-8-bit images was also slightly incorrect.

2003-09-30 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

coders/bmp.c (ReadBMPImage): scaling of 5-5-5-bit and 5-6-5-bit images was slightly incorrect.

2003-09-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/tiff.c (ReadTIFFImage): When using the generic bit-stream marshaller to read colormapped/gray images, the slight performance improvement from creating a special case for matte images did not justify almost doubling the amount of code. Therefore, the two loops are combined back into one.

2003-09-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/tiff.c (ReadTIFFImage): Fixed reading grayscale TIFFs that have a transparency channel. Now uses a generic bit-stream marshaller to allow reading any grayscale or colormapped TIFF with any bits per sample in the range of 1 to 16.
magick/bit_stream.h: Added a generic implementation for marshalling from a bit-stream into a quantum. Still needs re-writing for best performance.
PerlMagick/t/tiff/read.t: Added a test case for reading 8-bit grayscale TIFF with matte. Corrected grayscale 12-bit read signatures. Added 16 color PseudoClass read test. Added 4-bit grayscale read test.

2003-09-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/tiff.c (WriteTIFFImage): Add support for writing DirectClass grayscale images at 4 bits per sample, including those with an opacity channel. This allows writing smaller files (half the size) when the image has 16 (or less) levels of gray. Use "gm convert inimage.tiff -depth 4 outimage.tiff" to quickly create grayscale TIFF file with 16 (or less) levels of gray.

2003-09-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

NEWS: Updated NEWS file with changes since last update.
index.html: Added a link to the www/AUTHORS.html file, as well as text stating that GraphicsMagick is originally derived from ImageMagick 5.5.2, with a link to the ImageMagick site.
Makefile.am: Add rules to generate www/AUTHORS.html.
www/AUTHORS.html: New HTML file based on the AUTHORS file in the source package. GraphicsMagick has many authors.

2003-09-25 William Radcliffe <billr@corbis.com>

magick/image.c: Updated DescribeImage to cleanup EXIF data display based on work by Cristy in ImageMagick.

2003-09-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

coders/tiff.c (WriteTIFFImage): Add support for writing colormapped TIFF images with 1, 2, & 4 bits per colormap index. This allows writing smaller files.

2003-09-24 Lars Ruben Skyum <lars.skyum@stibo.com>

coders/ps3.c: Now creates a correct %%BoundingBox for images with resolution stored as pixels per centimeter. Renamed serialize functions. Added comment headers where they were missing. Reformatted code to be in alignment with GraphicsMagick standard formatting.
magick/map.c: Fixed semaphore double locking problem in MagickMapCloneMap.

2003-09-23 Mike Chiarappa <mikechiarappa@libero.it>

BCBMagick/readme.txt : Updated compilation instructions.
BCBMagick/magick/libMagick.bpr : Updated project, now include map.c.

coders/ps3.c: Fixed handling the case when no -coder-options are provided to the PS3 coder.

2003-09-22 Lars Ruben Skyum <lars.skyum@stibo.com>

coders/ps3.c: Changed %%Creator version to use MagickLibVersionText, increased precision in HiResBoundingBox, added a coder specific option for rendering bilevel images with the PS imagemask operator indstead of the image operator.
magick/command.c: Added "-coder-options" command line argument to all relevant command line utilities. Option argument to -coder-options is a list of comma separated key-value pairs that are saved in a MagickMap in ImageInfo for (de-)coders to use. See PS3 coder for an example that checks for: -coder-options "ps:image=imagemask"
magick/image.c, magick/image.h: Added function AddCoderOptions().
magick/map.c, magick/map.h: removed MS-DOS line terminators.

locale/C.mgk: Eliminated the many "NotA" messages since they may all be considered forms of "ImproperImageHeader". It is useful to provide the origin of such messages in case the wrong coder has been invoked, however, this is expensive to do via the message database since it explodes the number of messages. The exception logging can help here. Once the exception reports include the reporting entity, it will be more clear when the software misbehaves.
magick/error.h (ThrowReaderException2): Remove since no longer used.
(ThrowReaderException): Simplified implementation so that ThrowException is not expanded twice.
magick/error.h (ThrowReaderException3): Remove since never used.
coders/xtrn.c (ReadXTRNImage): Use ThrowReaderException rather than ThrowReaderException2.
locale/C.mgk (MissingArgument) Updated to include %s so that the description field appears earlier in the message.
magick/error.c (DefaultErrorHandler): Added a hack to allow the 'reason' member to include a %s so that it may specify the formating of the message. Care should be taken to not over-use this hack.

coders/ps3.c: Major update of the PS3 coder. Now ascii85 encodes all binary data. Many printer spoolers don't like the binary data. The coder now creates much smaller files for bilevel, gray, and colormapped images. Compression and image type is now separated so they may be combined independently. Any alpha channel is separated into a separate mask so it's possible to mask bilevel, gray, colormapped, rgb, and CKYK images. You may also mask a JPEG compressed PS file for instance. Clipping masks created from a photoshop clipping path with -clip option is converted to a corresponding postscript clipping path. New functions need comment headers.
magick/attribute.c: Added TracePSClippingPath for creating a postscript clipping path from a photoshop clipping path.
magick/compress.c, magick/compress.h: Added write-hook based interface to compression functions. Required for ascii encoding compressed, binary data. The interface between blob write functions, compression functions, and encoding functions could benefit from more of this work.
magick/image.c: ClipPathImage now stores the name of the clipping path in the mask image filename so that it is remembered and may be used for
