- 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.
- magick/nt_base.h: Avoid conflict with ssize_t definition under MinGW.

2004-05-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- ltmain.sh: Fix to allow exe wrapper to work under MinGW.

2004-05-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/enhance.c (NegateImage): If image has a clip mask, then force image to DirectClass so clip mask takes effect.

2004-05-15 Vladimir Lukianov <lvm@integrum.ru>

- magick/image.c (SetImageOpacity): Ensure that image is DirectClass. If specified opacity is TransparentOpacity, then replace existing opacity with TransparentOpacity.

2004-05-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/utility.c: Released 1.1.1.

2004-04-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- 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.
- magick/command.c (DisplayImageCommand): Eliminate double-free of resource_info->image_geometry. (DisplayImageCommand): 'display' was improperly requiring at least one argument (bug was added yesterday).

2004-04-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- 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>

2004-04-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/compress.c (HuffmanEncode2Image): Avoid out of bounds array access.

2004-04-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- configure.ac: Fix minor shell syntax error (used ==).

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

- 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.

2004-03-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- version.sh (PACKAGE_CHANGE_DATE): Updated version to 1.1Beta3
- magick/nt_base.c (NTSystemComman): Have not been successful with using MsgWaitForMultipleObjects() reliably, so back out usage of it for now.
- 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>

2004-03-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- 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>

- NEWS: Updated with changes up to today's date.
- tests/constitute.c (main): Float type seems to require allowing a bit of error for Q:32.
- 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>

2004-03-10 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/.

- 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.

- magick/resize.c (HorizontalFilter): Fixed: do process K channel for CMYK images.
  (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>

- 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>

- 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.

- 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.

  (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/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/locale.c: Use a Unix-style message database for MinGW.
- rungm.sh.in: Translate environment paths to Windows format when running under MinGW.
- 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>

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.
- libtool.m4: Updated to 2004-01-03 version of CVS libtool. This should fix configure problems under AIX and IRIX.

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/pixel_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>

- 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.
- BCBMagick/lcms/Projects/BCB6/lcms.bpr : Updated project, now include cmscam02.c and cmsvirt.c.
  Much thanks to Alex Dvoretsky for bringing this problem to my attention.

2003-09-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.h (Image): Moved private members to bottom of structure.

- magick/image.h (_Image): Changed 'Semaphore *' to 'void *'.
- magick/command.c: Updated each invokation of MagickMapAddEntry() to add an exception argument.
- tests/maptest.c: Updated to pass an exception argument to MagickMapAddEntry.
- magick/image.c (AddCoderOptions): Added exception argument and some more error handling.
- magick/map.c: Added formal documentation for methods. (MagickMapCloneMap): Added exception argument. (MagickMapAddEntry): Added exception argument and status.

2003-09-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/emf.c: Changed NotAnEMFFile to ImproperImageHeader.
- magick/map.h: Changed all size parmeters from type 'unsigned long' to 'size_t'.
- magick/map.c (MagickMapCopyBlob): Add new function to support copying a Blob in a MagickMap.
  (MagickMapDeallocateBlob): Add new function to support deallocating a Blob in MagickMap.

2003-09-23 Lars Ruben Skyum <lars.skyum@stibo.com>

- 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.

2003-09-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- tests/maptest.c (main): Test/demo program for key,value map API.
- magick/map.c, magick/map.h: Implementation of a key,value map API for internal use.

2003-09-19 William Radcliffe <billr@corbis.com>

- lcms/include/icc34.h lcms.h: Added back the icc34.h header and changes to make lcms compile on Win32" icc34.h lcms.h.

2003-09-19 Lars Ruben Skyum <lars.skyum@stibo.com>

- coders/ps3.c: Fixed warnings from Solaris compiler.

2003-09-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- 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.

2003-09-18 Lars Ruben Skyum <lars.skyum@stibo.com>

- 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 creating a postscript clipping path for postscript output.
- coders/modules.mgk: Added EPS3 mapping to module PS3.

2003-09-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/command.c: Coalesced various "Missing" error reports into one "MissingArgument" error report in order to reduce the number of messages to be maintained.
- locale/C.mgk: Removed almost all "Missing" messages.
- magick/gm_messages.mc: Added Microsoft message compiler source file to CVS until which time it may be generated automatically during the build.

2003-09-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- locale/Makefile: Added ability to generate gm_messages.mc (for Windows message compiler) as well as adding 'clean' and 'install' targets.
- magick/delegate.h: Visual Studio .NET 2003 doesn't like the chaining of GhostscriptVector members which share a common return type. Splitting the definitions solves this problem.

2003-09-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/deprecate.h (MagickSignedType): Compatibility definition to handle ImageMagick API change. (MagickUnsignedType): Compatibility definition to handle ImageMagick API change. The new names are just as useless as the old names, but at least they are shorter.
- magick/command.c: Linux's sscanf has the terrible bug that it improperly handles pulling out the first floating value from the string "0x1". Instead of retrieving the value 0 and returning 1, it returns 0, probably because it rejects the string as a hex constant. As a result, all options which used sscanf to validate this input are now converted to use IsGeometry().

2003-09-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- ltdl/ltdl.c: Update to libltdl current as of today.
- ltmain.sh: Update to libtool current as of today.
- configure.ac: For HPUX C++ compiler, add -AA to CXXFLAGS rather than CXX.

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

- configure.ac: Decided that the standards conformance defines create more problems than they solve so they are removed.
  Move the large-file tests to before the libtool configuration since the libtool configuration was causing stdlib.h to be included prior to the large file defines, and this causes header failure with C++ under AIX.
- www/api/types.html: Update description of MonitorHandler.

2003-09-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- configure.ac: Set CXX to PTHREAD_CXX if necessary (and warn).
- acinclude.m4 (ACX_PTHREAD): Add check to see if xlC_r should be used for AIX.

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

- magick/render.c: Fixed handling of arc primitive (see IM-5.5.8).

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

- magick/log.h: It seems that test programs are using GetMagickModule so make it visible by default.
- configure.ac: Use GM_FUNC_MMAP_FILEIO macro to test mmap.
- acinclude.m4 (GM_FUNC_MMAP_FILEIO): New macro to test mmap's capability to do coherent file I/O. The AC_FUNC_MMAP macro was not testing the mmap features that GraphicsMagick uses, and was failing on a number of systems.
- magick/blob.c (BlobMapModeToString): Only include this static function if HAVE_MMAP is defined.
- coders/locale.c (WriteLOCALEImage): Fix FormatString argument type inconsistencies.
- wand/magick_compat.h: Change MagickExport to WandExport.
- coders/jpeg.c, coders/locale.c, coders/meta.c, coders/miff.c, coders/palm.c, coders/pict.c, coders/svg.c, coders/tiff.c, coders/topol.c, magick/cache.c, magick/display.c, magick/image.c, magick/widget.c: Removed unused values, changed storage types, or added explicit casts, in order to reduce the number of "REMARK"s when using the SGI IRIX compiler.
- magick/render.c (DrawClipPath): Fix memory leak of clone_info->clip_path. Problem reported by Vladimir <lvm@integrum.ru>.
  (DestroyDrawInfo): Remove unnecessary checks for non-null prior to invoking MagickFreeMemory. MagickFreeMemory already checks for non-null.
- magick/log.h (GetCurrentFunction): Apparently Visual C++ 6.0 does not support __FUNCTION__. Problem reported by Vladimir <lvm@integrum.ru>.
- wand/magick_compat.c: All functions in magick_compat.c must use WandExport rather than MagickExport. Fix recommended by Vladimir <lvm@integrum.ru>.
- magick/constitute.c (PushImagePixels): number_pixels was always cast to a long during use, so change to store value in a long instead.
  (PopImagePixels): number_pixels was always cast to a long during use, so change to store value in a long instead.

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

- coders/psd.c: Eliminated warning regarding unused initialized variable.
- magick/log.c: Eliminate type warnings regarding enum assignment.
- coders/locale.c (WriteLOCALEImage): Use UndefinedException rather than 0 in severity_list terminating entry in order to avoid a type conversion warning.
- magick/image.c (SetImageChannelDepth): Depth parameter was being returned rather than status. Oops!
- magick/effect.c (BlurScanline): Due to automatic casting conventions, computation was being done (at least with SGI compiler) as type 'unsigned long' rather than 'long' as it should have been.
- coders/jpeg.c, coders/meta.c, coders/miff.c, coders/msl.c, coders/palm.c, coders/pcd.c, coders/psd.c, coders/svg.c, coders/tiff.c, coders/xcf.c, magick/render.c, : Quench many SGI compiler warnings regarding variables which are initialized but never used.
- magick/xwindow.h: Undef gravity defines so that enumerated type is used instead.

2003-09-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/log.c (LogMagickEvent): Windows system logging functionality is not currently ported to work with Cygwin so disable when compiling under Cygwin.
- magick/log.c (Win32EventlogOutput): Remove spurious comma in enum.
- wand/drawing_wand.h: Remove junk comment marker that I forgot to remove.
- magick/studio.h: Provide prototypes for strlcpy and vsnprintf if the system doesn't provide them in the requested compilation environment.
- configure.ac: Add necessary standards compilance definitions to magick_config.h.
  Check for strlcpy and vsnprintf prototypes.
- Makefile.am (DOCDIRS): www/api/types does not exist anymore.

2003-09-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- configure.ac: Move multithread tests prior to libtool configuration in case value of CC is changed. Otherwise libtool gets confused and refuses to run.
- acinclude.m4 (ACX_PTHREAD): If using AIX CC 'xlc' use 'xlc_r' for multithread compiler.
- coders/jpeg.c: Undef HAVE_STDLIB_H before including the jpeg headers or else we get an already defined error/warning.

2003-09-04 Mike Chiarappa <mikechiarappa@libero.it>

- BCBMagick : Updated whole directory tree to achieve correct compilation with Borland C++ Buider 6.0.

2003-09-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.c (ClipPathImage): Remove MS-DOS line terminations (actually, extra carriage returns) which somehow crept into ClipPathImage.
- locale/C.mgk: Added message for "PNG library is too old".

2003-09-04 Lars Ruben Skyum <lars.skyum@stibo.com>

- magick/transform.c (ProfileImage): Bugfix: conditional compilation based on LCMS being present or not now works as expected. An exception is thrown if LCMS is not present and profile conversion is used.

2003-09-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/txt.c (ReadTXTImage): Fix strlen() pointer type warning.
- magick/image.c (TextureImage): Fixed return with no value warning.
- magick/color.c (GetColorInfoArray): Decided that the const return value was a bad idea. Therefore, the return type has been made non-const.
- magick/magick.c (GetMagickInfoArray): Decided that the const return value was a bad idea. Therefore, the return type has been made non-const.
- tests/constitute.c, tests/rwblob.c, tests/rwfile.c : Define MAGICK_IMPLEMENTATION since these test programs using some internal extensions.
- configure.ac: Test C++ compiler for __func__ support.
- magick/log.h: Added GetCurrentFunction() macro to handle __func__ support determination. Re-wrote GetMagickModule() macro to use GetCurrentFunction(). Changes should allow compilation of Magick++ when the C compiler supports __func__ but the C++ compiler does not.
- configure.ac: Changed from using HAS___func__ define to HAS_C__func__ since this feature may be language sensitive.
- locale/C.mgk: Added missing JNGCompressionNotSupported message.

2003-09-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/attribute.c (Generate8BIMAttribute): Fix sscanf argument type mis-match.

- coders/wpg.c: Applied patch from Fojtik Jaroslav to support reading WPGs which use the EXT token.

2003-08-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/color.c (HistogramToFile): Renamed static method 'Histogram' to 'HistogramToFile' to make it more clear what this function does.
  (GetColorHistogram): Added new function to support retrieving a color histogram of the image. A color histogram contains a count of how many times each color occurs in the image.
- magick/image.c (GetImageChannelDepth): Return an 'unsigned int' rather than 'long'.

2003-08-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- PerlMagick/Magick.xs: Add support for CopyCyan, CopyMagenta, CopyYellow, and CopyBlack, composition operators.
- magick/composite.c (CompositeImage): Added support for CopyCyanCompositeOp, CopyMagentaCompositeOp, CopyYellowCompositeOp, and CopyBlackCompositeOp, composition operators.

2003-08-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- wand/*: Updated to current ImageMagick Wand API (minus a few unimplemented functions).
- magick/image.c (TextureImage): Add status return because Wand API wants it. Inherit is_grayscale status from texture image.
- magick/fx.c (SolarizeImage): Add status return because Wand API wants it.
- magick/resource.c (SetMagickResourceLimit): Add status return because Wand API wants it.
- magick/draw.c (DrawPeekGraphicContext): Now returns a copy of the current DrawInfo context rather than returning a pointer into the context stack. The user must destroy this copy using DestroyDrawInfo() once it is no longer needed.

2003-08-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- VisualMagick/filters/LIBRARY.txt: This file is necessary to incorporate analyze.c into the static build. Without it the build fails.

2003-08-23 Lars Ruben Skyum <lars.skyum@stibo.com>

- magick/transform.c: ProfileImage updated to handle alpha channels and grayscale images. Also optimized color profiling of color mapped images and fixed a few bugs in profiling of CMYK images.
- magic/locale_c.h: added MagickExport to prototype declaration of GetLocaleMessageFromID in WriteLOCALEImage again. Please update your locale coder.

2003-08-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/wpg.c: Applied patch from Fojtik Jaroslav to use the GetMagicInfo() function to obtain the format of embedded images, and to provide a default WPG palette if the WPG file does not supply a palette.

2003-08-22 William Radcliffe <billr@corbis.com>

- magick\gm_messages.bin locale_c.h transform.c: Fixed missing message problem and added support for new lcms error handler.

2003-08-21 Lars Ruben Skyum <lars.skyum@stibo.com>

- magick/attribute.c, magick/image.c, magick/command.c: Added "clippath" option for clipping named Photoshop clipping paths, increased precision in clipping path knots, added comments, and fixed a few bugs resulting from moving TraceClippingPath function from ImageMagick to GraphicsMagick. Still need to update some of the documentation.
- magick/locale_c.h, magick/studio.h: added MagickExport to declaration of GetLocaleMessageFromID and moved include of magick/locale_c.h after declaration of MagickExport. This fixes a link error in dynamic, DLL version.
- coders/locale.h: added MagickExport to prototype declaration of GetLocaleMessageFromID in WriteLOCALEImage.

2003-08-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- PerlMagick/t/subroutines.pl (testRead): Ignore useless TIFF warning so that 12-bit TIFF test passes.
- magick/constitute.c (ReadImage): Ensure that the reported image magic string is that of the user-specified input file rather than a temporary file prepared by an external delegate program.
- magick/command.c (ImportImageCommand): Since DestroyExceptionInfo() now sets the destroyed exception signature to an invalid value, GetExceptionInfo(exception) must be invoked when the intention is to simply purge the exception. This fix resolves an abort when executing 'gm import'.

2003-08-18 William Radcliffe <billr@corbis.com>

- magick\gm_messages.bin locale_c.h transform.c: Updates that add latest enhancments by Lars to color management code in ProfileImage.

2003-08-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2003-08-18 William Radcliffe <billr@corbis.com>

- PerlMagick/Magick.xs: Some fixes to get PerlMagick compiling again due to new ID based error macros.

2003-08-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/error.h (enum): Remove spurious comma.

2003-08-17 William Radcliffe <billr@corbis.com>

- coders\png.c: Had to modify a few exception calls to work with newest macros.

2003-08-17 William Radcliffe <billr@corbis.com>

- coders\locale.c magick/error.h locale.c locale_c.h studio.h: The LOCALEH header file generator now adds an MGK_ prefiix to all the ID defines as part of a fix to support the new error and exception macros cross platform.

2003-08-16 William Radcliffe <billr@corbis.com>

- wand\magick_wand.c pixel_wand.c: The wand api code was totally left out of the large macro conversion below as an oversight.

The main thing that was done was to remove all the quotes around the "tags" used to lookup messages defined in the locale\C.XML file. Macros were added to error.h to allow the code to be compiled for either string based access or binary ID based access. Using binary ID's will cause the code to fail to compile if a message does not exist in C.XML, since no ID will be created for a missing message. This change then allowed us to easily track down all the messages that were "missing" or not being accessed properly. The problems were massive and took many days to resolve. I have left the code compiling in ID mode to keep things in sync going forward and also because it makes message lookup instantaneous. An ID is just an index into and array of char *'s. There is still a lot of cleanup work remaining, but this is a very good start.

2003-08-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/error.c (GetLocaleExceptionMessage): Add check to avoid duplicating severity prefix.
- magick/log.c (LogMagickEvent): Incorporated fix from Bill Radcliffe to enable logging control flags to work properly again.
- NEWS: Updated news.
- magick/blob.c (OpenBlob): Rewind file descriptor so that first read is at zero offset. This fixes reading GIFs via a user-provided file handle.

2003-08-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.c (GetImageDepth): Extend so that the actual minimum depth required to represent the image is returned. Previously only the values 8, 16, and 32 were returned. This means that a value of one is returned for a monochrome image. Also fixed a bug in that the pixels were incremented while the depth was incremented, resulting in the first image pixels not being properly evaluated for depth. (SetImageDepth): Extend to support converting the image to arbitrary modulus depths.
  (GetImageChannelDepth): New function to obtain the modulus depth for a specified image channel.

2003-08-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/draw.c (MvgAutoWrapPrintf): StreamError reported when DrawError was intended.
- coders/logo.c (ReadLOGOImage): Report FileOpenError rather than BlobError if requested image does not exist.

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

- magick/cache.c (PersistCache): If HAVE_SYSCONF and _SC_PAGE_SIZE are defined, then assume that sysconf works and don't use legacy getpagesize() function.
- magick/studio.h (_XOPEN_SOURCE): Should be defined as 600 in order to match _POSIX_C_SOURCE=200112L according to the Single UNIX Specification v3. This is necessary for the vsnprintf prototype to be visible.
- magick/attribute.c (ReadByte): Fix compilation warnings due to casting 'unsigned char *' to 'char *' by changing function definition to accept 'unsigned char *' instead.
- magick/error.h (UndefinedException): UndefinedException should be ExceptionType, not ExceptionBaseType.
- magick/magick.c (IsValidFilesystemPath): Eliminate warning about unused function when UseInstalledMagick is defined.
- magick/error.c (ThrowLoggedException): Fix improper parameters passed to LogMagickEvent() when reason is not available.

003-08-07 William Radcliffe <billr@corbis.com>

- magick/log.c, log.h: Added ability to log by either severity or by category of event. Made the defualt on windows to log all fatal errors, errors, and warnings to the event log. This will include anything generated by exceptions currently, but not any normal "informational" logging.

2003-08-07 William Radcliffe <billr@corbis.com>

- magick/log.c, log.h: Translation of event codes to mask vals was not working. Code was left out of last update. It is now in.

2003-08-07 William Radcliffe <billr@corbis.com>

- magick/error.c: Protect against NULL string passed into the message lookup function.

2003-08-07 William Radcliffe <billr@corbis.com>

- magick/locale.c: Switched use of IsAccessible to nonloggging version to prevent recursive problems.

2003-08-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/Makefile.am (noinst_HEADERS): Distribute locale_c.h.
- locale/Makefile: Output locale_c.h.
- utilities/gm.c (main): Fix typo in Unix InitializeMagick invocation.
- configure.ac: Use ACX_PTHREAD pthreads test macro.
- magick/(semaphore.c,spinlock.h,studio.h): Change HasPTHREADS conditional define to HAVE_PTHREAD.
- magick/Makefile.am (noinst_HEADERS): Include spinlock.h in distribution.

2003-08-06 William Radcliffe <billr@corbis.com>

- contrib\win32\ATL7\ImageMagickObject/ImageMagickObject.cpp, ImageMagickObject_.h, ImageMagickObject.def, ImageMagickObject.rc gm.rc: Changes to get things compiling again since all windows specific logging support has been eliminated. The special build script BuildImageMagickObject.cmd now compiles the message file for resource based messages. The result is in gm_messages.bin. The script also generates a special version of gm.exe that uses the COM dll as a regular DLL and links to it. This is the long desired Moby DLL build idea.
- magick/error.c, magick/error.h, magick/log.c, magick/log.h: Upgrade of logging system to take over previous special logging code for windows in nt_base.c. The new logic provides logging of events to the debug api and the windows event log and also provides a generic text file logging method.
- magick/gm_messages.bin, magick/ImageMagick.rc: New compiled message file based on data in locale\C.mgk. RC file modified to include this as a resource.
- magick/locale.c, magick/locale_c.h: locale_c.h is generated by the LOCALEH format of the locale coder. The logic in locale.c uses the tables in the header lookup messages. On windows, all the messages are stored as resources, while on UNIX they remain in a string table.
- locale/C.mgk: Removed duplicate messages and added some new default messages that help to create a complete set of severity strings.
- magick/command.c, magick/magick.c: Get rid compiler warnings.

2003-08-05 William Radcliffe <billr@corbis.com>

- magick/command.c, magick/gm.c: Application level changes to implement the client name - filename changes. The client name can now be anything that the application wants and has nothing to do with the saved filename of the application.
- magick/nt_base.c, magick/nt_base.h, magick/magick.c: Ripped out old nt specific debugging and logging logic. Moving to the standard logging. New and major revisions to InitializeMagick to make the code more maintainable, reliable, and reaable. It should be functionally identical, but implements the new split client name and filename methododology.
- magick/utility.c, magick/utility.h: Added a couple of new routines to support splitting the overloaded use of the client name and client filename.
- coders/xtrn.c: Minor code cleanup

2003-08-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- Copyright.txt: Added missing copyright notice which is required due to copying the rlecomp manual page into ImageMagick.
- doc/config_files.imdoc: Started documentation for configuration files.
- magick/xwindow.c (XSignalHandler): Ensure that segment_info is non-null before attempting to use it. Much thanks to John Cristy for bringing this problem to our attention.

2003-08-05 William Radcliffe <billr@corbis.com>

- coders/locale.c: Added several new formats to this coder to generate windows message resource format messages and also to generates a new header file format that will support a table based version of the other magick/locale.c.

2003-08-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- configure.ac: Only configure C and C++ libtool tags.
- PerlMagick/t/reference/composite/*.miff: Added some composition test reference images. These reference images will serve as placeholders until better composition tests can be figured out. It is not clear from the documentation what some of the composition operators are supposed to do.

2003-08-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- README.txt: Add documentation regarding using TRIO.
- configure.ac: Test for TRIO library if vsnprintf is not available.
- magick/studio.h: Remap vsnprintf to trio_vsnprintf if TRIO is available.
- coders/topol.c, coders/wmf.c, magick/magick.c, magick/nt_base.c, magick/resource.c: Use traditional C comment form in C source files.

2003-07-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/log.h (LogEventType::AllEvents): Increase the value of AllEvents so that it spans the complete positive range of a signed integer.
- magick/xwindow.c, magick/xwindow.h: Incorporate patch from John Cristy's ImageMagick to eliminate conditional dependence of magick/xwindow.h on <X11/extensions/XShm.h>.
- magick/magick_config_api.h.in: HasSharedMemory define no longer needed.

2003-07-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2003-07-29 Troy Edwards <vallimar@sexorcisto.net>

- GraphicsMagick.spec: Updated to CVS build. Added the GraphicsMagickWand files to the spec. Only try to remove the unneeded perl package files if we are using PerlMagick.

2003-07-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- GraphicsMagick.spec: Added RPM spec file authored by Troy Edwards <vallimar@sexorcisto.net>.
- NEWS: Add note regarding EXIF fix.
- magick/attribute.c (GenerateEXIFAttribute): Look for the profile name "EXIF" rather than "APP1".

2003-07-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/magick_config_api.h.in: XWindowInfo structure in xwindow.h needs HasSharedMemory define.

- coders/dps.c, magick/xwindow.h: Move DPS includes to coders/dps.c
- coders/Makefile.am: Substituted values are also set as make variables, so use variables rather than substitutions.
- magick/log.c (GetLogBlob): MAGICK_HOME needs to take precedence over the client path for the uninstalled build.
- magick/type.c (GetTypeBlob): MAGICK_HOME needs to take precedence over the client path for the uninstalled build.
- magick/blob.c (GetConfigureBlob): MAGICK_HOME needs to take precedence over the client path for the uninstalled build.
- magick/module.c (FindMagickModule): MAGICK_HOME needs to take precedence over the client path for the uninstalled build.

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

- magick/nt_base.h: Add a typedef for ssize_t
- magick/deprecate.h: ExtendedSignedIntegralType and ExtendedUnsignedIntegralType are now deprecated types so they are moved to deprecate.h. Existing code which uses these types should continue to work.
- magick/blob.c (MapBlob): Change 'offset' parameter from type off_t to magick_off_t so that it is not LFS dependent.

- magick/image.c: (SetMagickInfo): Don't mask failure to read magic.mgk.
- magick/constitute.c (ReadImage): Don't overwrite specific exception info.
- magick/nt_base.c (NTResourceToBlob): Add logging similar to that used in IsAccessible() in order to make operation more clear.
- magick/module.c (FindMagickModule): Removed extraneous "Searching for module file" log event. (GetModuleBlob): Under Windows, don't clear or overwrite an existing exception.
- magick/nt_base.h: Imported some obscure defines from magick\magick_config.h.
- VisualMagick/magick/magick_config.h.in: Improved description text and formatting. Moved some obscure defines to magick/nt_base.h.
- locale/C.mgk: Added a "RegistryKeyLookupFailed" error message.
- magick/type.c (GetTypeBlob): Report registry key lookup failures. Also ensure correct return value when an error is reported.
- magick/log.c (GetLogBlob): Report registry key lookup failures.
- magick/delegate.c (ReadConfigureFile): Report registry key lookup failures.
- magick/blob.c (GetConfigureBlob): Report registry key lookup failures. Also ensure correct return value when an error is reported.
- magick/module.c (FindMagickModule): Report registry key lookup failures. Also ensure correct return value when an error is reported.
- magick/nt_base.c (NTRegistryKeyLookup): Simplify base key lookup code, and improve coding style.
- coders/logo.c, Copyright.txt, www/Copyright.html: Acknowledge and respect the XFig copyright.
- VisualMagick/installer/inc/files-documentation.isx: QuickStart.txt is no longer distributed so it is removed.

2003-05-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.h (RoundToQuantum): New macro to round positive double to Quantum.
- magick/xwindow.c, magick/xwindow.h, magick/studio.h: Use FreeBSD portability fixes from FreeBSD ports collection.
- configure.ac: Test for <machine/param.h> as used by some *BSD systems.
- QuickStart.txt, www/QuickStart.html: Don't distribute QuickStart.txt or www/QuickStart.html since the content doesn't currently apply to GraphicsMagick.

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

- README.txt: Added text regarding where to obtain dcraw, a simple but useful decoder for the proprietary raw file formats produced by digital cameras (58 supported cameras!).
- configure.ac: Added support for finding dcraw.
- VisualMagick/bin/delegates.mgk: Added support for dcraw.
- coders/delegates.mgk.in: Added support for dcraw.
- version.sh (PACKAGE_RELEASE_DATE): Extract the most recent update date from the ChangeLog file using awk.

2003-05-12 William Radcliffe <billr@corbis.com>

- modules.mgk, magic.mgk : Sync up both of these for UNIX as well as VisualMagick builds. Includes changes for the meta.c code.

2003-05-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- www/formats.html: Documented embedded gray intensity images.
- coders/logo.c: Added the embedded dithered gray intensity images gray0, gray5, ..., through gray100 to support bilevel filling and painting with an intensity resolution of 5%.
- www/formats.html: Added description of images available via "IMAGE:" format tag, as well as providing a tiled preview.
- coders/logo.c: Renamed "transparent" image to "checkerboard" since it is a better description. Added a set of tiny bilevel images (accessed via IMAGE:) for use when tiling, filling, or for use as a texture image. The complete set of image names available via the IMAGE: coder are now BRICKS, CIRCLES, CROSSHATCH, CROSSHATCH30, CROSSHATCH45, FISHSCALES, GRANITE, HEXAGONS, HORIZONTAL, HORIZONTALSAW, HS_BDIAGONAL, HS_CROSS, HS_DIAGCROSS, HS_FDIAGONAL, HS_HORIZONTAL, HS_VERTICAL, LEFT30, LEFT45, LEFTSHINGLE, LOGO, NETSCAPE, OCTAGONS, RIGHT30, RIGHT45, RIGHTSHINGLE, ROSE, SMALLFISHSCALES, CHECKERBOARD, VERTICAL, VERTICALBRICKS, VERTICALLEFTSHINGLE, VERTICALRIGHTSHINGLE, & VERTICALSAW. The HS_* variants are similar to the standard pattern images provided with the Windows GDI.
- coders/msl.c (MSLStartElement): Don't reset gravity if the user provides an x,y coordinate. Passing coodinates was loosing the gravity setting.

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

- coders/modules.mgk: Support the IMAGE: format via the LOGO module.
- win2k/IMDisplay/IMDisplayView.cpp (DoDisplayImage): Transparent tile is created by reading "tile:image:transparent".
- coders/logo.c (ReadLOGOImage): Add IMAGE: format to front for embedded images so that adding new images doesn't proliferate coder registrations. Legacy logo magick names (GRANITE, LOGO, NETSCAPE, and ROSE) are still supported, but they are also available in the IMAGE file space (e.g. IMAGE:ROSE).

2003-05-09 William Radcliffe <billr@corbis.com>

- VisualMagick\configure : Further refinements that support both the new "big" library and the normal dynamic DLL buidling styles.

2003-05-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/logo.c (ReadLOGOImage): Added a "TRANSPARENT" pattern image which can be tiled to form the background of transparent images.
- win32/IMDisplay/IMDisplayView.cpp: When displaying images which include an opacity channel, use a checker-board pattern as the image background so non-opaque pixels become evident.

2003-05-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/meta.c : Add or fix commenting of DebugString so that module does not require Windows.
- lcms: Updated to release 1.10.

2003-05-07 William Radcliffe <billr@corbis.com>

- VisualMagick\bin : Brought the MGK files back into sync with the rest of the package and added types for meta.c.
- VisualMagick\bin\win32\ATL : removed config files in order to prevent very old ATL project from being picked up in the config

2003-05-06 William Radcliffe <billr@corbis.com>

- VisualMagick\lcms\LIBRARY.txt : a define to prevent popup message box behaviour.
- VisualMagick\configure\ : New feature - -t consolidates all the coders into on library for the static build in order to make the build process tolerable.
- coders\xtrn.c : new support for BSTR - wdie character data
- coders\svg.c : put back logic that allows the -size parameter to control the pixel dimensions of the output image.
- coders\meta.c : added support for wide character parsing of iptc and 8BIM formats.

2003-05-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- version.sh : Update to reflect development status.

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

- GraphicsMagick 1.0 Released.
- version.sh (LIBRARY_REVISION): Updated for the 1.0 release.
- magick/studio.h: Add fix to avoid problems caused by zlib under AIX.
- magick/cache.h: Parameterized prototypes to make them easier to follow.
- filters/analyze.c: Replace C++ comments with C comments.
- magick/command.c: For the composite, convert, identify, mogrify, and montage commands, make sure a usage error is returned if a usage message is printed. This is useful for ImageMagickObject users who won't see the usage message if stdio is not supported.
- locale/C.mgk: Added "UsageError" error. Added missing closure to <Corrupt> tag which caused most/many message lookups to fail.
- magick/nt_base.h: Fixed a compile problem caused by masking internals in delegate.h
- magick/ImageMagick.rc: Added missing .mgk files.

2003-05-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/nt_base.c (lt_dlerror): Defining lt_dlerror to be NTGetLastError was not a correct implementation since the interface is defined to return a const pointer to a string, but NTGetLastError returns an allocated string, causing a memory leak if NTGetLastError is used in the place of lt_dlerror. A new lt_dlerror function is added to fix this. (lt_dlsetsearchpath): lt_dlsetsearchpath should return an int and accept a const char *.
  (lt_dlsym): lt_dlsym is supposed to take a const char *.
- magick/nt_base.h: lt_dlclose should return an 'int'.
- magick/nt_base.c (lt_dlclose): Return status from lt_dlclose.
- magick/module.c (lt_dlclose): lt_dlclose is supposed to return an 'int', not 'void'. A return value of zero indicates success.
- VisualMagick/tests/run_constitute.bat: Add batch script to run constitute tests.
- magick/module.c: Added a ltdl_initialized static flag to track if libltdl has been initialized by lt_dlinit(). (TagToFunctionName): Use a stack buffer for the string rather than allocating heap data.
  (UnregisterModule): Report errors via exception info as the interface suggests.
  (UnloadModule): Report errors via exception info as the interface suggests.
  (DestroyModuleInfo): Only invoke lt_dlexit() if lt_dlinit() has previously been invoked.
- locale/C.mgk: Added FailedToCloseModule module error.
- magick/module.c (UnloadModule): Report exception via exception parameter rather than simply printing out an error message and exiting.
- magick/Makefile.am (noinst_HEADERS): integral_types.h had to be listed *somewhere* in order to make it into the distribution.
- Magick++/lib/Magick++/Image.h: InitializeMagick must be DLL exported.

2003-05-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- Makefile.am (magick-version): Perform version.isx substitutions via Makefile.am rather than configure.
- magick/magick_config_api.h.in: Added template header for the installed magick_config.h.
- magick/magick.c (InitializeMagick): Improved the signal handling and registration method. Signal handlers are only registered for a signal if the current signal handling disposition for that signal is set to the default (SIG_DFL). When a signal is caught, DestroyMagick is invoked, the handling for the signal is set back to SIG_DFL, and then the signal is re-raised to trigger the default handler for that signal. This causes the process to behave as closely to the default as possible (e.g. generating a core file) while ensuring that DestroyMagick is executed. This also ensures that signal handlers registered by API users are not overridden by invoking InitializeMagick.
- configure.ac: Added tests for sigemptyset and sigaction.
  Add a check for the return type of signal handlers. Test for the 'raise' function.
- www/formats.html: Add an entry for CUR, Microsoft Cursor Icon format.

2003-05-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/semaphore.c (struct SemaphoreInfo): Added `locked' and `thread_id' members. These are used to record if the semaphore is locked, and to validate the thread ID of the unlocker.
- www/links.html: Added link to Nathan Day's MagickDocs "ImageMagick and GraphicsMagick documentation project" site.
  Added a link to an on-line article regarding the PHP front-end to ImageMagick.
- coders/icon.c (ReadIconImage): Add support for Windows .CUR format based on advice from Jean Piquemal.
- magick/image.c (SetImageInfo): Added missing CloseBlob in error path for failure to allocate temporary file.
- coders/pcx.c (ReadPCXImage): Added support for reading uncompressed PCX images based on code from Jean Piquemal.

2003-05-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/effect.c (AddNoiseImage): For gray images, wrong pointer was being used to evaluate intensity, leading to a black image with noise.
- magick/image.c (ChannelImage): Return the channel image in RGBColorspace. Also properly support extracting the opacity channel for images which are not CMYK.

2003-04-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/Makefile.am (install-data-local): Install magick_config_api.h rather than magick_config.h.
- magick/api.h: Removed inclusion of integral_types.h from magick/api.h. It is included by magick/studio.h.
- magick/delegate.h: Mapped out a block of private implementation code.
- configure.ac: Perform substitutions on magick_config_api.h.
- magick/magick_config_api.h.in: New header file template to use for installed magick_config.h.
- magick/studio.h (MAGICK_IMPLEMENTATION): Added the define MAGICK_IMPLEMENTATION used to enable private types, includes, and defines in the headers. This supports hiding implementation stuff that API users shouldn't see in the headers.
- utilities/Makefile.am (check): Cleaned up the utilities test/demo a bit as well as using the undocumented "tmp:" prefix to cause GraphicsMagick to remove temporary input files once they have been read. This leaves just the final output file "demo.miff" when the test completes.
- coders/jpeg.c (WriteJPEGImage): If the image resolution is overwritten with 72DPI, make sure that the resolution units are set to PixelsPerInchResolution.
- coders/jpeg.c (WriteJPEGImage): Don't overwrite the image resolution if it is valid.
- magick/command.c (MogrifyImageCommand): Added -resample option to match documentation.
- VisualMagick/configure: Added rpcrt4.lib to project settings for Visual C++ 6.0 so that configure links. The code which needs these interfaces is to support Visual C++ 7.0 XML-style project files.

2003-04-30 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- utilities/Makefile.am (check) Change % to %% in -label parameter.
- www/gm.html, utilities/gm.1, etc. Documented use of %% to convey the % sign in -format, -comment, -label strings.

2003-04-30 William Radcliffe <billr@corbis.com>

- magick/command.c: Changes from 2003-04-19 to free the arg list when it was still pointed to by the option arg and accessed on an exception. This caused gm to crash on any erroneous command line argument.

2003-04-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- www/windows.html: Updated to match current installer.
- VisualMagick/installer/inc/tasks-install-devel.isx (Name): Added an installation checkbox so the user can select to install development headers and libraries for C & C++.
- VisualMagick/installer/inc/files-perlmagick.isx (Source): Only install PerlMagick PPD files if the user selects to install PerlMagick.
- VisualMagick/installer/inc/files-com.isx (Source): Only install ImageMagickObject files if the user selects to install ImageMagickObject.
- magick/version.h.in: Added some documentation for the functioning of MagickLibVersion and MagickLibVersionNumber.
- configure.ac: Perform substutions to create VisualMagick/installer/inc/version.isx from VisualMagick/installer/inc/version.isx.in. This allows Windows versioning info to be updated from info in version.sh.
- Makefile.am (magick-version): For a VPATH build, update VisualMagick/installer/inc/version.isx in the source directory if it is out of date.

2003-04-28 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- magick/cache.c: CloneImagePixels(): applied Cristy's bugfix from IM-5.5.7.

2003-04-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- www/api.html: The demo program on the ImageMagick API page is usually intended to be an exercise for the reader. It rarely compiles or works. Sure enough the demo code was not even close to compiling, didn't run, and did something totally different than described. This is not a good way to treat new users. Now the demo program compiles and runs, and its description is correct.
- www/magick.css, www/smile.c: Remove "Pair" advertisement which was discovered appended at the end of these files.
- coders/jpeg.c (ReadJPEGImage): Check for failure of AllocateImage. Close blob prior to error return.
- configure.ac: Perform substitutions on magick/version.h
- magick/version.h.in: New file to provide base for configured magick/version.h
- version.sh (PACKAGE_RELEASE_DATE): Support setting a package release date.
- configure.ac: Perform substitutions on PerlMagick/Magick.pm.in to create PerlMagick/Magick.pm.in.
- PerlMagick/Magick.pm.in: @PACKAGE_VERSION@ is substituted while configuring PerlMagick/Magick.pm.
- magick/magic.mgk, VisualMagick/bin/magic.mgk: Removed risky entry for PICT which has been demonstrated to lead to a false match in the real-world.
- coders/pict.c (ReadPICTImage): Ensure that PICT decoder don't loop forever with an EOF condition if none of the PICT op-codes encountered result in a condition which terminates the input loop. If EOF is dectected while in the input loop a "corrupt image" "unexpected end of file" error is reported.
- VisualMagick/installer: Updated installer.

2003-04-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/magick.c, magick/blob.c, magick/studio.h: Added Compilation fixes recommended by Harold Bien for for Borland C++.
- www/contribute.html: Added text regarding contributing to GraphicsMagick.
- www/api/types.html: Documentation for GraphicsMagick API types moved from www/api/types/*.html into this one file. Types documentation is still very much under development.
- README.txt: Added note regarding the download location for free Windows fonts which are kindly made available by Microsoft.
- VisualMagick/installer/gm-dynamic-full-*.iss: Install nt_base.h and nt_feature.h.

2003-04-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- www/windows.html: Updated for GraphicsMagick 1.0 and to link to ImageMagickObject.html.
- www/programming.html: Added link to ImageMagickObject.html.
- www/ImageMagickObject.html: New file to provide some documentation for ImageMagickObject.
- www: Found and fixed broken URL links.

2003-04-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- FlashPIX: Applied patches from FreeBSD. Bumped package version to version to 1.2.0.8.
- www/api.html: Updated to reflect GraphicsMagick
- www/*.html: Updated with format_c_api_docs script.
- Makefile.am (format_c_api_docs): Add a target to update the C API documentation.
- scripts/format_c_api_docs: Add script which extracts and formats the C API documentation into HTML files in the www/api subdirectory.

2003-04-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- version.sh (PACKAGE_VERSION): Update release version ID.
- magick/version.h (MagickReleaseDate): Update release date.
- magick/constitute.c (ConstituteImage): Fixed problems with reading intensity (gray) pixel arrays.
- magick/image.c (GrayscalePseudoClassImage): Use ScaleQuantumToIndex rather than ScaleQuantumToMap.
- magick/constitute.c (ConstituteImage): Use ScaleQuantumToIndex macro to scale integral intensity values to colormap range.
- magick/image.h (ScaleQuantumToIndex): New macro to scale a quantum to the maximum range of a colormap index. Useful when writing to PsuedoClass grayscale images.
- VisualMagick/tests/run_constitute.bat: Batch script to run constitute tests.
- VisualMagick/installer/*.iss: Updated for Beta1 release.

2003-04-22 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- utilities/Makefile.am (check) fixed typos (RM -> RMDelegate and removed stray "gm"), added -random-threshold, ordered-dither.
- magick/effect.c: Random-threshold was not treating non-gray PseudoColor images correctly.

2003-04-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- utilities/Makefile.am (check): Added code to put logo on demo output.
- magick/command.c (MontageImageCommand): Pass exception rather than &image->exception because image may be null, and it is pointless to store the exception where it will not be reported to the user anyway.
- utilities/Makefile.am (check): Ported Glenn Randers-Pehrson's utilities demo script into the Makefile to serve as a check target.
  (check): Add definition to find Generic.ttf.
- locale/C.mgk: Fixed syntax error in <Option><FatalError> section.
- www/development.html: New file to describe development process.
- index.html, www/*.html: Added link to development.html and improved formatting a bit.

2003-04-21 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- Fixed bug with compiling png.c with libpng versions older than libpng-0.95.

2003-04-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- www/programming.html: Added links to Delphi and Scheme programming interfaces.
- configure.ac : Removed outdated test for jp2conf.h.

2003-04-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/command.c: Add argument expansion and deallocation code to command functions which lacked this functionality. Replace calls to Exit with a return to the invoking function.
- utilities/gm.c: Expect each subcommand to expand and deallocate its own argument list. Treat subcommands more similarly.
- magick/magick.c (InitializeMagick): Seed the random number generator.
- magick/utility.c (ExpandFilenames): Handle tilde expansion properly. Handle relative glob specifications. Skip over "*" argument to +profile properly. Don't expand VID: specifications since the VID: coder will execute ExpandFilenames() later. Apply format specifier prefix to globbed file names. Fix double frees and rationalize memory management by always copying to a new vector.

2003-04-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/magick.c (InitializeMagick): Decided to move clean-up signal-handler registration from gm.c to magick.c in order to ensure that resources are cleaned up for all library users. This means that if a user program wants to do something special for signals registered to be caught by InitializeMagick (SIGHUP, SIGINT, SIGQUIT, SIGABRT, SIGTERM, SIGXCPU, & SIGXFSZ) then the user program should register its own signal handlers after invoking InitializeMagick. The user is then responsible for making sure that DestroyMagick is invoked if an unexpected signal is caught.
- tests/Makefile.am (check-constitute): Added constitute tests.
- magick/constitute.c: New test program to ensure that ConstituteImage and DispatchImage are working correctly.

2003-04-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- www/download.html: Added links to directories at ftp.graphicsmagick.org.
- index.html: Add notice regarding 1.0 Beta0 availability.
- www/cvs.html: Updated CVS checkout information to include the GraphicsMagick-1_0 branch.
- coders/psd.c (ReadPSDImage): Applied patch (SourceForge patch ID 722849) from Derry Bryson to fix a memory leak. An image was being leaked.
- magick/constitute.c (DispatchImage): Applied patch (SourceForge patch ID 722655) from Derry Bryson to correctly use the switch_map array rather than the map array. Without this patch, DispatchImage does not work at all.
- GraphicsMagick 1.0.0-beta0 release.
- version.sh: Updated for beta0 release.
- *.c magick/*.h: Update header inclusion to include "magick/" prefix in order to ensure that there is no confusion with headers from another package.

2003-04-16 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- magick/effect.c: 4x4 ordered dither threshold was incorrect.

2003-04-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/resource.c (InitializeMagickResources): Added the ability to obtain the amount of physical memory by executing an external command.
- configure.ac: Check for getpagesize(). (MAGICK_PHYSICAL_MEMORY_COMMAND): Added a test for an external command which (quickly) returns the amount of physical memory installed on the machine. Currently only activated for FreeBSD. (MAGICK_PHYSICAL_MEMORY_COMMAND): Use sysctl to determine total physical memory for Darwin.
- magick/delegate.c (ListDelegateInfo): If COLUMNS environment variable is set, then use it to obtain the screen width. Some shells dynamically update COLUMNS, but COLUMNS may need to be explicitly exported in order for it to be seen by subordinate programs (such as gm).
- magick/effect.c (AddNoiseImage): Use IsGrayImage() to check if the image is gray. Add missing columns loop for intensity case (oops!).
- magick/command.c (DisplayImageCommand): Fix -dispose option processing bug reported by Felix Heimbrecht.
- coders/fpx.c: Check status from FPX_InitSystem().

2003-04-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- configure.ac: Define PERLMAINCC to be the C compiler if there are no C++ dependencies, or the C++ compiler if there are C++ dependencies.
- PerlMagick/Makefile.PL.in: Use PERLMAINCC to compile and link perlmain.c. This allows using the C++ compiler to link, which is useful when the build depends on C++ libraries like libfpx.
- ltmain.sh: Updated to libtool 1.5 release.
- Makefile.am ($(PERLMAGICK)/$(PERLSTATICNAME)): Add rules to make sure that static PerlMagick is linked against the current GraphicsMagick library.
- coders/miff.c (ReadMIFFImage): Properly scale colormap entries.
- magick/image.c (TransformRGBImage): Eliminate 32-bit integer overflow condition for Q:32 build while transforming CMYK pixels.

2003-04-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- PerlMagick/t/ttf/read.t: Updated signatures and reference image for FreeType 2.1.4.
- (PerlMagick/t/write.t, PerlMagick/t/montage.t, PerlMagick/t/rad/read.t, PerlMagick/t/rad/write.t): Fix signatures which were thrown off by previous change to how signatures are specified to functions in subroutines.pl.
- PerlMagick/t/cgm/read.t: Updated to use reference image.
- PerlMagick/Makefile.PL.in: Perform substitutions on generated Makefile to ensure that the proper -lGraphicsMagick is used for a static build.
- ttf: Updated to FreeType 2.1.4. Now stored in CVS as delegates/freetype2 rather than delegates/ttf so be sure to re-checkout the ttf directory so that the correct files are used.
- wmf/incude/libwmf/api.h: Updating FreeType caused a problem since it introduced a copy of zlib and api.h included zlib.h. Fixed problem by adding a typedef for gzFile and not including zlib.h.
- utilities/gm.c: Fixed minor compilation problem under Windows caused by a typo in the signal handler registration code.

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

- Makefile.am: When building a static PerlMagick, build PerlMagick as part of the 'all' target and don't do a 'make clean' of PerlMagick at install time.
- configure.ac (LIB_DPS): Add check to see if -lXt is required by -ldps. XFree86 -ldps requires -lXt.
- FlashPIX: FlashPIX library now compiles under FreeBSD 5.0.
- magick/deprecate.c (ValidateColormapIndex): Remove non-interface deprecated function.
- magick/tempfile.c (AcquireTemporaryFileDescriptor): Priortize use of mkstemp() over tempname() since *BSD compilers whine about tempname() (although we do use tempname() safely).
- magick/color.c (ConstrainColormapIndex): Removed function since it is no longer used.
- magick/utility.c (TemporaryFilename): Removed TemporaryFilename utility function since it is no longer used and it makes *BSD compilers complain.
- magick/studio.h: Don't define _ISOC99_SOURCE, _POSIX_C_SOURCE, or _XOPEN_SOURCE when compiling under FreeBSD since this maps out a 'ushort' definition required by /usr/include/sys/ipc.h.

2003-04-11 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- coders/png.c: Some grayscale PNG images and the JNG alpha channel were decoded improperly at Q:32.
- magick/constitute.c (PopImagePixels): Changed many instances of (Quantum) typecast to (unsigned char).

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

- PerlMagick/t/tiff/read.t: Added signature for 12-bit TIFF test and a Q:32 build.
- PerlMagick/t/subroutines.pl: Extended routines which are signature based to accept signatures for Q:32 as well.
- PerlMagick/t/wmf/read.t: Relax error values slightly to pass at Q:32.
- coders/miff.c (PushImageRLEPixels): Fix reading RLE MIFF at Q:32. A fragment of old code was being used to obtain the length.
  (WriteRunlengthPacket): Fix writing RLE MIFF at Q:32. In most cases the wrong scaling macro was being used.
- tests/Makefile.am (check-miff): Added MIFF tests for supported compression options.

2003-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/color.c (QueryColorDatabase): Extended to support parsing Q:32 hex color specification strings. Also add error reporting for failure to parse the color specification. This resolves a bug that drawing via the draw.c APIs was not working for Q:32 builds.
- utilities/gm.c (main): Add signal handlers to make sure that program cleans-up on exit by invoking DestroyMagick.
- magick/draw.c (DrawSetFillColor): Quote color specification.
  (DrawSetStrokeColor): Quote color specification. (DrawSetTextUnderColor): Quote color specification.
- ltmain.sh: Update to latest CVS libtool.

2003-04-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/enhance.c (NormalizeImage): Only normalize the opacity channel if image->matte is true. This results in some (15%) speedup. While it can be argued that the 'K' in CMYK should be normalized, it can also be argued that this is senseless since 'K' is not a "linear" measure like C, M, & Y are, and there may not be any any value to normalizing CMY at all.
  (EqualizeImage): Only equalize the opacity channel if image->matte is true. This results in a 23% speedup. (GammaImage): Minor loop optimization. (LevelImage): Don't level the opacity channel. Doing so doesn't make any sense.
  (LevelImageChannel): Put loops inside switch statement rather than around it.
- PerlMagick/t/tiff/read.t: Added grayscale 12-bit and 16-bit TIFF read tests.

2003-04-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/tiff.c (ReadTIFFImage): Add support for reading 12-bit grayscale TIFFs. Fix reading 16-bit grayscale TIFFs when QuantumDepth=8.
- VisualMagick/installer/gm-dynamic-full-8.iss, VisualMagick/installer/gm-dynamic-full-16.iss: Many C header files were not being included in the distribution. Oops!

2003-04-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- (index.html, www/*.html): Update to new web page style.
- scripts/txt2html: Update to output new web page style.
- ltmain.sh: Updated to latest CVS libtool.
- magick/tempfile.c (DestroyTemporaryFiles): Function was crashing if it was executed twice.

2003-04-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/delegates.mgk.in: Ralcgm was appending ".ps" to the provided output file name, so change cgm delegate command so that the input file is delivered via standard input, output is re-directed to a file, and anything printed to stderr (such as the Ralcgm program name and version) is sent to /dev/null.
- INSTALL-unix.txt: Added/corrected/improved documentation regarding --disable-installed, --enable-shared, and --with-modules.
- VisualMagick/magick/magick_config.h.in: Add more documentation and explanatory notes in order to lessen confusion.
- Many files: Replaced "UseInstalledImageMagick" with "UseInstalledMagick" for obvious reasons.

2003-04-04 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- magick/command.c, magick/effect.c: add -ordered-dither option.

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

- locale/C.mgk: Fixed message associated with "UnableToCreateTemporaryFile".
- magick/tempfile.c (AcquireTemporaryFileDescriptor): Decided to return a pathname (if possible), even on failure, for use in error reports. The function return status should be used to determine if the function has succeeded.
- locale/locale.mgk: Updated copyright header.
- (magick/annotate.c, magick/attribute.c, magick/blob.c, magick/cache.c, magick/constitute.c, magick/delegate.c, magick/display.c, magick/image.c, magick/locale.c magick/tempfile.c, magick/tempfile.h, magick/utility.c, magick/xwindow.c, coders/dcm.c, coders/ept.c, coders/histogram.c, coders/mpeg.c, coders/pdf.c, coders/pict.c, coders/preview.c, coders/ps2.c, coders/ps3.c, coders/ps.c, coders/pwp.c, coders/sfw.c, coders/svg.c, coders/tiff.c, coders/url.c, coders/wpg.c): Ensure that failure to allocate/create temporary file is properly detected and reported.

- configure.ac (MagickBinPathDefine): Added support for a MagickBinPath definition.
- configure.ac (GSVersion): Added test to obtain version of installed Ghostcript.
- magick/tempfile.c (AcquireTemporaryFileDescriptor): Open flag should have been O_RDWR, not O_WRONLY!

2003-04-03 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- magick/utility.c: Simplified skipping over the "*" in the +profile "*" option when expanding filenames.

2003-04-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- VisualMagick/bin/delegates.mgk: Update similarly to coders/delegates.mgk.in.
- coders/delegates.mgk.in: Replaced 'mpeg-decode' delegate specification with 'mpeg' delegate specification.
- PerlMagick/t/mpeg/read.t: Since -r option is no longer supplied to mpeg2decode, the signatures must be updated.
- magick/utility.c (ExpandFilenames): Skip over no-argument commands properly.
- coders/mpeg.c: Removed ReadMPEGImage since this is handled entirely by delegate now.
- magick/command.c: Add convert -temporary option for use when input files are temporary files which should be automatically removed.
- magick/delegate.c (InvokeDelegate): Ensure that temporary file access is secure.
- coders/ept.c (ReadEPTImage): Ensure that temporary file specified by image_info->filename is liberated before allocating a new temporary file name.

- coders/pdf.c (ReadPDFImage): Change TemporaryFilename to AcquireTemporaryFileName.
- magick/tempfile.c (LiberateTemporaryFile): Now takes a 'char *' argument rather than 'const char *', and erases the provided filename if it is the name of a valid temporary file. This helps avoid errors. The return status may be used to determine if a file was removed. (AcquireTemporaryFileDescriptor): Decided that adding a .tmp extension to temporary file names is unnecessary.
- coders/jp2.c (WriteJP2Image): Destroy pixel matrix after encoding image. Cristy says that there is memory corruption otherwise.

2003-04-01 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- coders/png.c: Use new temporary file manager for JNG components. Merge with IM 5.5.7 (mostly cosmetic changes).

- magick/tempfile.c: New temporary file allocation subsystem for allocating, tracking, and deallocating temporary files. Use of this subsystem should reduce the likelyhood that temporary files will be left behind once the process exits. If the environment variable MAGICK_TMPDIR is set, then its value is used as the location to place temporary files.
- magick/utility.c (IsAccessibleAndNotEmpty): New function for testing for file exists, is a regular file, and is not empty. Used to test if a temporary file has been updated by a delegate.
- magick/log.c (SetLogEventMask): Add support for setting TemporaryFileEvent.

2003-03-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- tests/Makefile.am : Removed some debug code which was accidentally committed to CVS.
- Copyright.txt: Add copyright statements to all the files, including some apparently missing copyrights.

2003-03-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/Makefile.am: Added temporary.c and temporary.h. These are not finished yet.
- magick/cache.c: Transferred optimization from ImageMagick to read/write all requested pixel cache rows in one system call when accessing the cache using file I/O, and the requested columns equals the image columns.
- magick/resource.c: (ResourceInfo): Use type 'double' rather than 'long double'. For many systems, the range of 'long double' is the same as 'double'. On others, use of 'long double' incurs the cost of function calls since there is no hardware support.

2003-03-22 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- magick/effect.h, effect.c, command.c: Revised -random-dither to require parameters: channel LOWxHIGH. Channel can presently be "intensity", "opacity", or "all".

- magick/image.h (RoundSignedToQuantum): Added handy RoundSignedToQuantum macro for munging doubles into Quantums.
- magick/effect.c (ThresholdImage): Added optimizations for thresholding all pixels to white or black. Threshold using an integral value rather than a double so compares are faster. (ChannelThresholdImage): Threshold against integral values since compares are faster. Invoke ThresholdImage for simple thresholding across all channels since it is faster.

2003-03-19 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- coders/meta.c: #ifdef'ed out some dead code.
- magick/annotate.c: #ifdef'ed out some code that is only used when HasTTF is defined.

  Cleans up some messy code, and makes it easy to use pread(). (FilePositionWrite): Inline wrapper for writing a chunk of data at an offset.
  Cleans up some messy code, and makes it easy to use pwrite(). Cache now uses pread() and pwrite() to access the cache if these calls are available.
- magick/resource.c (InitializeMagickResources): Support setting resource limits via the environment variables MAGICK_LIMIT_DISK, MAGICK_LIMIT_FILES, MAGICK_LIMIT_MEMORY, and MAGICK_LIMIT_MAP.

- magick/list.c (DestroyImageList): Update so that new DestroyImage assertions aren't asserted.
- coders/wpg.c (ReadWPGImage): Don't leave dangling pointer when trimming list. Don't set image->depth to invalid values.

2003-03-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.c (DestroyImage): Add assertions to verify that destroyed image is not currently referenced by another image. This should help prevent accidental continued use of a destroyed image.
  (DestroyImage): Added assertions to enforce that images should not continue to reference the destroyed image.
- coders/wpg.c: Incorporated fixes from Jaroslav Fojtik.
- version.sh (PACKAGE_VERSION_ADDENDUM): Construct a package snapshot version based on the ChangeLog modification time. This requires GNU find to work propery since the -printf option is used.
- configure.ac (LIB_GS): Do not test for the Ghostscript library by default due to the issue of its embedded libjpeg conflicting with libjpeg.
- coders/ept.c (ReadEPTImage): "PostscriptDelegateFailed" should be classified as a DelegateError type.

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

- magick/blob.c (BlobToFile): Truncate while opening file. (ImageToFile): Truncate while opening file.
- magick/annotate.c (RenderFreetype): Missing freetype library should result in a MissingDelegateError type rather than a DelegateError type.
- INSTALL-windows.txt: Added a note regarding a workaround for internal compiler errors while compiling image.c when using Visual C++ 7.0.
- coders/jpeg.c (ReadICCProfile): Incorporate ImageMagick fix to handle short JPEG ICC profiles.

2003-03-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.c (GetImageDepth): Re-implemented using a single-pass algorithm and 1/2 the code. Previous implementation didn't return correct results for Q:32 build. Now it does.
- magick/command.c (IdentifyImageCommand): For identify, when %q format specifier is present, image must be read rather than pinged. If not, either the value 8 is returned, or there is a crash due to reading an uninitialized image.

2003-03-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/blob.c: Fix some erroneous log printf specifications. Improved blob log messages a bit.
- magick/log.c (IsEventLogging): Use InitializeLogInfo(). (InitializeLogInfo): New function to intelligently initialize logging subsystem. Only locks when initialization may be required, and only locks long enough to determine if initialization is required. This approach should avoid deadlocking while logging from functions used to initialize logging.
  (IsLogAccessible): No longer need this duplicate of IsAccessible(). (SetLogEventMask): Use InitializeLogInfo().
- coders/fpx.c (ReadFPXImage): FlashPIX library does not support BLOB I/O so don't use OpenBlob/CloseBlob. Opening the blob caused a conflict when the FlashPIX library attempted to open the file.

2003-03-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- configure.ac: Test for libtiff functions (TIFFClientOpen & TIFFIsByteSwapped), which are required by GraphicsMagick, but not found in older libtiff versions.

- tests/rwfile.c (main): Add -pause option to require keypress to exit program. Clean-up to avoid any appearance of leaks.
- magick/static.c (ExecuteStaticModuleProcess): Don't bind in process filter functions for Visual C++ since the build environment doesn't support it yet.
- magick/log.c (GetLogBlob) Code wasn't actually testing current directory for log.mgk, now it does.
- magick/log.c (IsEventLogging): Eliminate accidental recursive, or repeated, initialization of the logging system.

2003-03-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/blob.c: Moved GetTypeBlob() to type.c and made it static. Moved GetModuleBlob() to module.c and made it static.

2003-03-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/Makefile.am: MIFF module does not depend on -ljpeg, but PNG module does (for JNG).
- filters/analyze.c (AnalyzeImage): Bugfix, image should be passed as Image** rather than Image*.
- magick/utility.c (IsAccessible): Don't log errno if errno==0.

2003-03-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2003-02-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/jp2.c (WriteJP2Image): Quality factor calculation had accidentally been removed. The calculation is back, but has been biased up slightly so that a quality factor of 75 results in a more reasonable 16:1 compression. Past a quality factor of 99.5, the compression is set to 1:1 (non-lossy).

2003-02-27 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- Fixed bug with reading interlaced PNG images, introduced yesterday.
- Fixed bug with skipping MNG subimages, also introduced yesterday.

- JNG alpha sample depth was sometimes inconsistent.
- Bring only one line at a time into memory during PNG read/write (Merge with Cristy's 5.5.6 update).

2003-02-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- PerlMagick/Makefile.PL.in (LIBS): Put MAGICKLIB first to decrease the probability that the wrong libMagick is used when linking static PerlMagick.

2003-02-24 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- png.c: Added missing parentheses in typecast (cristy noticed the bug that I introduced on 2/18).

2003-02-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- Makefile.am: Add rules to produce www/README.html, www/INSTALL-mac.html, www/INSTALL-unix.html, www/INSTALL-vms.html, and www/INSTALL-windows.html

- magick/cache.c (SyncCacheNexus): If image pixels are updated then set image is_grayscale and is_monochrome members to False. Algorithms which want to preserve the values of these members should save their original values before processing the image and restore them when processing is complete, or transfer them from the input image to the output image.
- magick/constitute.c (ReadImage): If the returned image is PseudoClass then invoke IsGrayImage() and IsMonochromeImage() and cache the result in image is_grayscale and is_monochrome members for later use.
- magick/image.h (Image): Added is_grayscale and is_monochrome members to remember if image is grayscale or monochrome.

2002-12-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.c: Re-worked TransformRGBImage() again so that it is now smoking fast for Q:8 and Q:16. Changed lookup tables, and all per-pixel transforms to use only integer arithmetic. A pre-multiplication scheme is used which should actually improve the quantization error over using double arithmetic. It is actually possible to improve Q:32 performance a bit more but is it worth the effort?

2002-12-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.c: Implemented logging for TransformRGBImage() and RGBTransformImage().

2002-12-24 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- The png codec would close the blob twice (second time raising an assertion) if a libpng error was encountered.
- Sometimes the PNG writer would receive an invalid bit depth from CompositeImages(); this is now ignored.

2002-12-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.c: Re-wrote TransformRGBImage() so that it does not penalize a Q:8 build. The function should be faster now, but no timings have been made to verify that.

2002-12-21 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- Elimimated unused transparent_pixel array in png.c.
- Reverted to incrementing loops in bmp.c where the counter "i" is used in the loop.

- magick/image.c, magick/command.c: Moved MogrifyImage and MogrifyImages from image.c to command.c in order to diminish unnecessary inter-object coupling. Only functions in command.c should use MogrifyImage or MogrifyImages. Some work remains to accomplish that.

2002-12-16 Cristy <cristy@mystic.es.dupont.com>

- coders/jpeg.c: Add missing break statements to fix colorspace handling when image colorspace is CMYKColorspace or YCbCrColorspace.
- magick/decorate.c: Cast to double in calculation.
- magick/enhance.c: Tweaks to equalization map calculation to (hopefully) provide more consistent results.

2002-12-12 William Radcliffe <billr@corbis.com>

- utilities/gm.c Fixes a crashing bug in gm.c caused by an attempt to free a bad pointer. Added comments to the code that explain why this happens so that future developers don't fall into the same trap.
- win2k/IMDisplay/IMDisplay.rc Modified some of the string resources that define supported file formats that were in error. One example was eps with had a *.eps in the string instead of just .eps. This caused the document class to ASSERT under the debug build.

2002-12-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- Enable the module loading code for shared/DLL builds regardless of whether the build is a "modules" build. This allows users to add their own modules without requiring the use of a special "modules" build.

2002-05-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- Text escaping for -draw and DrawAnnotation was not working properly. Now it does. Backslash should act as a escape for the the active quote character (', ", or }) as well as backslash. The backslash should be discarded if it was used as an escape character. In order to reliably pass a backslash, two successive backslashes are required (e.g. "\\").

2002-05-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2001-11-02 Cristy <cristy@mystic.es.dupont.com>

- Typecast offset to unsigned long in coders/pdf.c.

- Convert's -flatten, -average, etc. failed with an assert error.

2001-10-30 Cristy <cristy@mystic.es.dupont.com>

- Added support for On-the-air bitmap.

2001-09-29 Glenn <randeg@alum.rpi.edu>

- When the delay setting for an image is greater than 4cs, duplicate frames are inserted to achieve the desired delay while creating MPEG files (contributed by Lawrence Livermore National Laboratory (LLNL)).

2001-10-29 Cristy <cristy@mystic.es.dupont.com>

- ImageMagick now has a registry for storing image blobs.

2001-10-26 Cristy <cristy@mystic.es.dupont.com>

- Eliminated libMagick.so dependency on libxml by not listing -lxml when doing modules link.

2001-10-18 Cristy <cristy@mystic.es.dupont.com>

- Eliminated the libMagick.so dependancy on libtiff by moving Huffman2DEncodeImage() from magick/compress.c to coders/pdf.c, coders/ps2.c and coders/ps3.c (suggested by Bob Friesenhahn). This change has the side-effect of elminating dependency on libpng and libjpeg as well (which libtiff may depend on).

2001-10-16 Cristy <cristy@mystic.es.dupont.com>

- Convert now supports -channel {Cyan,Magenta,Yellow,Black}.

2001-10-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2001-09-30 Cristy <cristy@mystic.es.dupont.com>

- switched strcpy to strncpy to help protect against buffer overflow.
- ltdl.c passed int reference but a long was needed; caused a fault on Solaris 64-bit compiles.

2001-09-25 Cristy <cristy@mystic.es.dupont.com>

- Removed most lint complaints from the source.
- strtod() returns different results on Linux and Solaris for 0x13.
- Added a MATLAB encoder contributed by Jaroslav Fojtik.

2001-09-21 Cristy <cristy@mystic.es.dupont.com>

- Replaced TemporaryFilename() with UniqueImageFilename().
- ImageMagick CORE API is now 64-bit clean.

- PingImage() now reports attributes for all images in an image sequence.

2001-09-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.h: Rename QuantumLeap define to QuantumDepth. QuantumDepth is set to the values 8 or 16, depending on user configuration option.

- Updated PerlMagick signatures to reflect new message digest algorithm.

2001-09-08 Cristy <cristy@mystic.es.dupont.com>

- ImageMagick defaults to 16-bit quantum. Set QuantumMagick for 8-bit.
