2004-12-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• magick/image.c (DescribeImage): Add normalized channel statistics to output.

• NEWS: Updated with changes since July.

• magick/constitute.c (ImportImagePixelArea): For GrayQuantum, GrayInvertedQuantum, GrayAlphaQuantum, and GrayInvertedAlphaQuantum, observe image storage_class so that a gray DirectClass image may be created.

• coders/tiff.c (ReadTIFFImage): Fix overflow when computing colormap size for bits-per-sample of 32. (WriteTIFFImage): Support writing 32-bit RGB(A) for QuantumDepth=32 build.

2004-12-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• coders/tiff.c (WriteTIFFImage): TrueColor 16-bits/sample RGB images were being written incorrectly on little-endian CPUs. Added byte swapping to fix this problem.

2004-12-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• magick/operator.c: New file for quantum operator implementation. (QuantumOperatorImage): Moved from image.c. (QuantumOperatorRegionImage): Moved from from image.c.

2004-12-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

• magick/Makefile.am (MAGICK_BASE_SRCS): Remove mention of non-existent mmath.h.

2004-12-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

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

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

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

• coders/jpeg.c (ReadJPEGImage): Fix GCC warning about variable being clobbered by longjmp.

• Re-port build to MinGW. Modules build passes all tests.

• Skip build and install of modules if a key library is not available.

• Partial recode of metadata handling to use Get/Set profile functions. Big job!

• coders/tiff.c: Don't use deprecated tiff.h _SUPPORT defines. Support retrieving and saving XMP profile. Use profile set/get methods in implementation.

• coders/mat.c,coders/topol.c (ReadBlobWordLSB,ReadBlobDoublesLSB): Use better variable name than I for image.

2004-09-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• coders/miff.c (WriteMIFFImage): Ensure that MIFF files are never written with bogus compression values.

• magick/image.h: Protected/hid constants which only exist to support the library implementation.

• tests/Makefile.am (TESTS_X11_XFAIL_TESTS): Fixed syntax error.

• Makefile.am: Use one Makefile to rule them all as described in Peter Miller's excellent paper, Recursive Make Considered Harmful, "http://www.pcug.org.au/~millerp/rmch/recu-make-cons-harm.html". Some glitches may remain.

• coders/tiff.c (TIFFErrors): Prevent possible stack overflow on error. (TIFFWarnings): Prevent possible stack overflow on error.

• magick/constitute.c (ImportImagePixelArea): For RGBQuantum initialize the opacity channel since it is easier than altering all code to properly access it.

2004-09-02 Glenn Randers-Pehrson <glennrp@glennrp.com>

2004-08-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• PerlMagick/t/tiff/write.t: Adjusted file naming.

• PerlMagick/t/tiff/read.t: Added more tests.

• coders/tiff.c (ReadTIFFImage): Use ImportImagePixelArea to read PseudoClass tiff. (WriteTIFFImage): Allow user to set the bits-per-sample define to any value in the range of 1 to 32. (ReadTIFFImage): Fix endian-reordering for DirectClass read and bits-per-sample values ranging 9-15.

• coders/gray.c: Support reading & writing 32-bit depths for raw gray images.

• magick/deprecate.c (PopImagePixels): Deprecated function. (PushImagePixels): Deprecated function.

• magick/constitute.c (ExportImagePixelArea): New function to export pixel region using specified QuantumType and bits-per-sample. (ImportImagePixelArea): New function to import pixel region using specified QuantumType and bits-per-sample.

2004-08-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• magick/cache.c (ClonePixelCache): It appeared that cloning a disk-based pixel cache was limited to the maximum value of size_t. This would result in a truncated cache. The offset type is changed from size_t to magick_off_t in order to avoid this.

• configure.ac: Check to see if the char type is unsigned, mostly out of curiosity since the code does not currently make use of the result.

• Fixed many compilation warnings when the compiler warning level is set as high as possible.

• configure.ac: Check /usr/share/ghostscript/fonts for Ghostscript Type1 fonts.

2004-08-13 Glenn Randers-Pehrson <glennrp@glennrp.com>

• tEXt and zTXt were inadvertently included in list of unused chunks.

2004-08-09 Glenn Randers-Pehrson <glennrp@glennrp.com>

2004-08-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• magick/widget.c (XCommandWidget): Replace ImageMagick logo in display command menu with GraphicsMagick logo.

2004-08-05 Glenn Randers-Pehrson <glennrp@glennrp.com>

• coders/png.c: Fixes for CERT security alert TA04-217A described at "http://www.us-cert.gov/cas/techalerts/TA04-217A.html".

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

• magick/image.h (Image): Changed type of colors and depth members from type unsigned long to unsigned int. This change is made because on 64-bit CPUs, unsigned long is a 64-bit type. The depth member is often used in switch statements. It is not recommended to use 64-bit types in switch statements. The maximum number of colors in the colormap is limited to 64K so a 64-bit type is not required.

2004-08-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• coders/tiff.c (ReadTIFFImage): Restore previous 8/16 bits-per-sample support code in order to regain lost performance.

2004-07-20 Mike Chiarappa <mikechiarappa@libero.it>

• lcms/src/cmsio1.c: Test [testcms.c] related to lcms 1.13 fail with error #12288 when perform "Checking saved linearization devicelink". Fixed function __cmsSaveProfile(). "...malloc(0) is implementation dependent and may return non NULL pointer on some compilers, like VC++ and gcc. This is not the case of Borland C++ Builder" - Thanks to Marti Maria that have supplied me this patched file: this will be part of the next lcms 1.14 which probabily will be released on summer's end.

2004-07-20 Mike Chiarappa <mikechiarappa@libero.it>

• BCBMagickmagickmagick_config.h.: enabled LZW compression by default.

• BCBMagick: included jbig delegate library.

  • Modified these files into directory BCBMagick: AllbcbMagick.mak; AllGMlib.bpg; AllGMdll.bpg; coderslibCoders.bpr; magickGM_magick.bpr; utilitiesgm_lib.bpr; utilitiesgm_dll.bpr

2004-07-09 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

• coders/bmp.c (ReadBMPImage): Removed if-test on reading red_mask, green_mask, and blue_mask. These are only *valid* under certain conditions, but they are always present in the file.

2004-07-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• Enable LZW compression by default.

2004-07-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• coders/jpeg.c (WriteJPEGImage): Don't enable Huffman compression for large images (> 16 Mpixels for the moment) in order to conserve memory. When Huffman compression is enabled the entire image is buffered in memory prior to encoding and writing anything. Huffman compression is a method of eliminating redundant data so when the Huffman compression is disabled, files sizes will be larger, but otherwise the image is the same.

• wand/magick_wand.c (MagickSetPassphrase): String was being copied to a null pointer. Now memory is allocated as required prior to a copy. Ensure that all unimplemented functions return a proper error report.

• magick/command.c (MogrifyImage): For -units, don't reset resolution if units are undefined. Report an error if the -units argument is not supported.

2004-06-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• magick/command.c (MogrifyImage): When setting image units, also adjust existing image x_resolution and y_resolution so that existing image resolution is not trashed. (MogrifyImage): When re-sampling an image, report an error if the image does not contain a valid resolution.

2004-06-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• coders/pcx.c (WritePCXImage): Support writing large PCX files. (WritePCXImage): Ensure that UndefinedResolution is handled properly. Avoid round-off error for centimeter based resolution.

2004-05-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• 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.

2004-05-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• utilities/Makefile.am (check): Add convert -list tests.

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.

2004-05-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• magick/constitute.c (DispatchImage): Support 8-bit output to common formats BGR, BGRO, BGRP, RGB, RGBO, and I as special cases in order to improve performance.

(NormalizeImage): Properly return error status.

• magick/image.c (GetImageClipMask): New function to retrieve an associated clip-mask image. (SetImageClipMask): Clip-mask image parameter may be const since it is cloned prior to storage. (ChannelImage): Properly return error status. (GradientImage): Properly return error status. (RGBTransformImage): Properly return error status. (TransformRGBImage): Properly return error status. (SyncImage): Return an error status.

• 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.

2004-04-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• configure.ac: Avoid duplicated test status messages for __func__ tests. Avoid duplicated test status message for jpeg 6b test.

2004-04-19 Patrick Welche <prlw1@newn.cam.ac.uk>

• www/header.html: HTML syntax fixes.

2004-04-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• : Change web pages to a frames-based design.

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/symbols.h (GetMagickDimension): Added GetMagickDimension.

2004-04-11 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.

• 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).

• 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): Encoding bug is indeed fixed on DEC Alpha. Also warnings reduction with Digital Unix compiler.

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

• magick/compress.c (Ascii85Tuple): Add casts to reduce compiler warnings, and maybe even fix a bug.

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

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

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

• magick/studio.h (_FILE_OFFSET_BITS): Fix _FILE_OFFSET_BITS #ifdef to avoid warnings when it is not defined.

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>

• Merged in updates from 1.1 release branch.

• version.sh (PACKAGE_VERSION): Release version 1.1. (PACKAGE_VERSION): Next major release will be 1.1. Bump library versions since we anticipate adding interfaces.

• 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. (GetExecutionPathUsingName): Complete re-write in order to minimize path computation logic and fix failure with partial paths.

2004-03-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

• doc/options.imdoc: Add "Color" to the arguments available for -list.

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/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>

• 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/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.

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>

• 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/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.

• 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>

• 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.
