	loading may result in duplicate entries.

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

	* libtool: Update to libtool 1.2.4.
	* GraphicsMagick.spec.in: Add --with-included-ltdl to the default

	libltdl dependency argument as required for building.
	* configure.ac: Intuit if the GraphicsMagick library will depend
	on -lltdl.
	* Magick++/bin/GraphicsMagick++-config.in: Use substitutions
	rather than invoking GraphicsMagick-config in order to determine
	GraphicsMagick library usage requirements.  This avoids problems
	when GraphicsMagick-config is not in the executable search path.

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

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

	CPU.

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

	* magick/magick.h (MagickInfo): Remove image_info member since I
	can not find any purpose for it.
	* coders/tiff.c (WriteTIFFImage): Remove assertion check on
	scanline size since it has not caught anything.
	* magick/image.c (SetImageInfo): Ensure that the file extension
	does not trigger unwanted activity such as access to an X11
	server, printer, or the launch delegate.
	* config/Makefile.am (configshare_DATA): Install colors.mgk in
	share path.
	* magick/blob.c (GetConfigureBlob): Search 'share' config path
	prior to 'lib' config path.

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

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

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

	* BENCHMARKS.txt: Added a benchmark summary.

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

	* version.sh: Prepare 1.2beta1 release.
	* NEWS.txt: Updated with latest news.

	support.
	(SetImageChannelDepth): Added progress monitor support.
	(ChannelImage): Don't preserve matte channel when extracting
	channel.
	* magick/image.c (SetImageOpacity): Avoid integer overflow in Q32
	build.  Added progress monitor support.

	supposed to be using it!
	* libtool: Updated to GNU libtool 1.2960 2008-04-19.
	* configure.ac, magick/delegate.h: It seems that the modern
	convention is to store ghostscript headers in a subdirectory
	called 'ghostscript' rather than 'ps'.
	We don't actually need Ghostscript errors.h and that is a good
	thing since it seems that some newer Ghostscript calls it ierrors.h

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

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

	* magick/compress.h: Clean up interface definitions to use
	magick_uint8_t for unsigned character data.
	* coders/jpeg.c (ReadJPEGImage): Don't use GetPixelCachePresent()
	since it is not DLL-exported.

	system.  Resource specifications are now absolute except that they
	support a binary metric suffix such as 'K' to scale the value.
	Added the 'Pixels' limit type to limit the maximum number of
	pixels allowed for each image.

	* png: Updated libpng to 1.2.26.

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

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

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

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

	* magick/utility.c (MagickCreateDirectoryPath): New function to

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

	* coders/tiff.c (WriteTIFFImage): Added a simple sentinel
	assertion to hopefully flush out any remaining cases where
	ExportImagePixelArea() writes past the end of its buffer.
	* magick/constitute.c (ExportImagePixelArea): GrayQuantum case for
	DirectClass pixels was sometimes writing a zero byte one past the
	end of the allocated buffer.  Thanks to Josue Gomes for reporting
	this bug.

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

	* coders/{pcd.c,pcx.c,pdb.c,pict.c,stegano.c,wpg.c,xcf.c}:
	Warnings reduction.	
	* magick/{channel.c,image.c,unix_port.c,render.c}: Warnings
	reduction.
	* coders/mat.c: Convert C99 comments to C89 comments so code can

	allocated for the scanline.
	* NEWS.txt: Updated with latest NEWS.

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

	* coders/pdf.c (WritePDFImage): Default to ZIP compression if

	* PROCESS.txt: Convert description of development process to
	reStucturedText format and generate HTML version from it.
	* INSTALL-windows.txt: Add instructions for how to install from
	setup.exe style installer.  Also add instructions for how the
	distribution package is built.
	* Copyright.txt: Reformat in reStucturedText format and generate
	HTML version from it.
	* VisualMagick/installer/inc/body.isx: No longer include
	development headers and libraries in the Windows DLL install
	package since they are large and they may only work with the
	version of Visual C++ used to perform the build.  It is much safer
	for the developer to build the package from source with his own
	compiler.

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

	* Fix compilation issues with Microsoft Visual Studio.

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

	* coders/dpx.c (ReadDPXImage, WriteDPXImage): Use lookup tables to
	speed up value conversion.
	* magick/memory.h (MagickAllocateArray): Renamed from
	MagickAllocateMemoryElements.

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

	* PerlMagick/Magick.xs: Use memory allocation macros like the rest
	of the code.
	* magick/memory.c (MagickMalloc): New function which behaves
	similar to malloc().
	(MagickMallocArray): New function for allocating an array.

	the memory allocation functions.
	* magick/memory.h: New header file to define memory allocation
	functions.
	* magick/deprecate.c (DeleteImageList, DestroyImages,
	GetImageList, GetImageListIndex, GetImageListSize, GetNextImage,
	GetNumberScenes, GetPreviousImage, ParseImageGeometry,
	PopImageList, PostscriptGeometry, PushImageList,
	SetCacheThreshold, SetImageList, ShiftImageList, SizeBlob,
	SpliceImageList, UnshiftImageList): Remove functions which were
	already deprecated in ImageMagick 5.5.2 or earlier.

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

	* coders/dpx.c (WriteDPXImage): Support writing image which is

	* magick/attribute.c (CloneImageAttributes): New function for
	copying image attributes from one image to another.
	* magick/utility.c (TranslateTextEx): Check if the pixel cache is
	initialized before using a function which requires using it.
	Thanks to Micha³ Kowalczuk for bringing this issue to my
	attention.
	* magick/attribute.c (SetImageAttribute): Only apply
	transformations to "comment" and "label" attributes.

	improved performance.
	* magick/image.c (GetImageDepth): Use table lookups to improve
	performance.

2008-03-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (AllocateImage): Transfer any attributes from
	ImageInfo to allocated image.
	(SetImageDepth): Use table lookups to improve performance.

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

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

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

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

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

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

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

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

	* coders/xbm.c (ReadXBMImage): ditto
	* coders/xcf.c (ReadXCFImage): ditto
	* coders/dib.c (ReadDIBImage): ditto
	* coders/dcm.c (ReadDCMImage): ditto

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

	* coders/tiff.c (WriteTIFFImage): The RFC 2301 specification for
	Internet FAX recommends LSB2MSB fill order so document that.

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

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

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

	* configure.ac: Updated to latest CVS libtool.
	* coders/tiff.c (CompressionSupported): Use
	TIFFGetConfiguredCODECs() to test if a requested compression type
	is supported by libtiff.  Based on advice from Frank Warmerdam.
	* configure.ac: Add test for TIFFGetConfiguredCODECs() in libtiff.

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

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

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

	* VisualMagick/installer/inc/setup.isx: Set Inno Setup installer
	compression to "lzma/max".
	* PerlMagick/Magick.xs: Eliminate use of memory allocation macros
	since these failed miserably under Windows where it seems that
	malloc, free, and realloc are redefined via macros by the Perl
	build environment.  This reverts changes made on 2007-12-01.
	* magick/memory.c (MagickAcquireMemoryArray): Use implementation
	from the 1.1 branch.
	* magick/utility.h: Remove MagickSafeMultiplySize_t since it seems
	that use of inline functions in Windows is a disaster area.

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

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

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

	* coders/tiff.c (WriteTIFFImage): Add logging for image resolution
	and resolution units.
	* magick/version.h.in: Update copyright year to 2008.

2008-02-01  Gary V. Vaughan  <gary@gnu.org>
	
	* configure.ac: Updated for libtool-2.1b.
	* bootstrap (libtoolize): Libtoolize can figure out the mode and
	directory for libltdl from configure.ac.

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

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

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

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

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

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

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

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

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

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

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

	* magick/command.c (VersionCommand): Include a "Large Memory" item
	in the Feature Support list.
	* coders/png.c (RegisterPNGImage): Remove reference to dead PNG
	ftp site.
	* VisualMagick/configure/configure.cpp (InitInstance): Remove
	project dependency on dxguid.lib (Direct-X).

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

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

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

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