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

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

2008-04-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtool: Update to 1.2965 2008-04-22

	a NULL pointer when reading JPEG sub-image.

2008-04-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

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

	* configure.ac, magick/Makefile.am: Don't use libtdl unless we are
	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.

	integer, with error checking.
	* magick/image.c (SetImage): SetImage now returns error status.
	* magick/command.c: Eliminated the long-deprecated -cache resource
	limit option.
	* magick/resource.c: Complete re-write of the resource limit
	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.

2008-04-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* 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

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

	* coders/pdf.c (WritePDFImage): Default to ZIP compression if
	available.  Ignore Image compression setting since the useful
	value (set by the user) usually comes from ImageInfo.

	* CONTRIBUTE.txt: Convert contribute.html to reStucturedText
	format and generate HTML version from it.
	* 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.
	(MagickRealloc): New function which behaves similar to realloc().
	(MagickFree): New function which behaves similar to free().
	(MagickAllocFunctions): New function to allow the user to specify
	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
	already in a YCbCr colorspace.
	(ReadDPXImage): Return YCbCr images in YCbCr colorspace unless
	they are also Cineon log encoded.
	* magick/image.c (CloneImage): Use CloneImageAttributes().
	* 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 Micha Kowalczuk for bringing this issue to my
	attention.

	* magick/colorspace.c (RGBTransformPacket): Rationalize casts for
	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

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,

2008-02-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* PerlMagick/Magick.xs: Use MagickAcquireMemory() rather than
	AquireMemory().
	* coders/xwd.c (ReadXWDImage): Eliminate integer overflow
	vulnerability (IDefense 09.19.07).
	* 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.

2007-12-23  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* VisualMagick/configure/configure.rc: Better positioning of frog,
	changed original ImageMagick messages.

	* magick/command.c: Fix compilability issue for Microsoft Visual
	Studio 6.

2007-12-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Use some improved tests for POSIX standard types
	available in Autoconf 2.61.
	Add support for configuring a magick_uintmax_t type.
	Added support for configuring a magick_uintptr_t type.

2007-12-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/utility.h (MagickSafeMultiplySize_t): New function to
	perform a safe multiply.  A multiplication overflow results in
	zero.
	(MagickAllocateMemory): Check for size_t value truncation/overflow
	and zero size before deciding to allocate memory.  Any detected
	failure results in a NULL pointer being returned.
	(MagickReallocMemory): Add a type parameter to use in cast in
	order to avoid C++ portability problem.
	* PerlMagick/Magick.xs: Eliminate use of deprecated methods.
	* magick/memory.c (MagickAcquireMemory): New function to allocate
	memory.
	(MagickAcquireMemoryArray): New function to allocate memory for an
	array of objects.
	(MagickCloneMemory): New function to intelligently copy memory.
	(MagickReallocateMemory): New function to re-allocate memory.
	(MagickReleaseMemory): New function to deallocate memory.
	* magick/deprecate.c (AcquireMemory): Deprecated in favor of new
	function MagickAcquireMemory().
	(CloneMemory): Deprecated in favor of new function
	MagickCloneMemory().
	(LiberateMemory): Deprecated in favor of new function
	MagickReleaseMemory().
	(ReacquireMemory): Deprecated in favor of new function
	MagickReallocateMemory().

2007-11-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/constitute.c (ReadImage): Log colorspace of returned image.
	(WriteImage): Log colorspace of image to be written.
	* coders/{miff.c,mpc.c,tga.c,tiff.c}: Use MagickBoolToString().
	* magick/{constitute.c,xwindow.c}: Use MagickBoolToString().
	* magick/image.h (MagickBoolToString): New macro to convert truth
	value to a constant "True" or "False" string.

2007-11-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (IsImagesEqual): Allow comparing images if the
	colorspace enumeration is different but the images are both an RGB
	type.

2007-11-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c: Add support for -monitor option to 'animate',
	'display', and 'import'.
	* coders/fpx.c (WriteFPXImage): Fix compilation problem.

	integer calculations where possible.

2007-11-07  Andy Armstrong  <andy@hexten.net>

	* PerlMagick/t/setattribute.t: Fix for typo which breaks
	Test::Harness 3.00.

2007-10-20  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* mat.c: Attempt to read 'logic' type modification 
        as monochrome image.

2007-10-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/blob.c (ReadBlob?SBFoo): Return 0 on EOF conditions
	rather than a magic value concocted using ~0.  The magic value was
	very sensitive to the size/range of the type used to pass and
	store it, leading to increased possibility of error.  There was
	also concern that sometimes a successfully read value may match
	the magic value.  Added documentation that EOFBlob() may be used
	to determine that the blob is in EOF state.
	* coders/pix.c (ReadPIXImage): Avoid reliance on a particular
	magic value being returned from ReadBlobMSBShort on EOF.
	* coders/avs.c (ReadAVSImage): Avoid reliance on a particular
	magic value being returned from ReadBlobMSBLong() on EOF.

2007-10-07  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* wpg.c: Monochrome images are not using palette - 
	palette is discarded in this case.

2007-10-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/blob.h: Blob I/O APIs now use sized types so that passed
	and returned data values are a specific size rather than
	architecture dependent.
	* PerlMagick/t/read.t: Added read test for unsigned 32-bit LSB MAT
	format.

2007-10-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dib.c (ReadDIBImage): Use appropriate sized cast for DIB
	width and height values.  Validate width and height values.
	* coders/bmp.c (ReadBMPImage): Use appropriate sized cast for BMP
	width and height values.
	* magick/colorspace.c (RGBTransformImage): Use a better rounding
	algorithm when converting to HSL/HWB colorspaces.
	* magick/gem.c (TransformHSL): Avoid GCC opimization bug on
	Opteron which caused wrong results.  Ensure that returned values
	fall within bounds 0.0 to 1.0.
	(TransformHWB): Avoid GCC opimization bug on
	Opteron which caused wrong results.  Ensure that returned values
	fall within bounds 0.0 to 1.0.
	* PerlMagick/t/ttf/read.t: Relax strictness quite a bit for TTF

	* configure.ac: Check for missing pread() and pwrite() prototypes.
	* m4/ac_func_fseeko.m4: Use fixed version of AC_FUNC_FSEEKO.
	* magick/utility.c (SystemCommand): Avoid use of snprintf.

2007-07-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/blob.c: Only replace getc_unlocked() and putc__unlocked()
	for a thread-safe build.
	* magick/studio.h: Always use fseeko() and ftello() if they are
	available.

2007-07-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (ReadDPXImage): Avoid using seek() if possible, and
	don't use at all if the input is not seekable.
	* coders/psd.c (ReadPSDImage): Eliminate memory leak when reading
	PSD files.  Fixes Sourceforge issue 1625477 "Memory leak reading
	layered PSD Image".

2007-06-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c: Fixed -affine command argument
	validation. Fixes SourceForge issue 1743141 "Affine matrix option
	parsing".
	* config/magic.mgk: Added detection for BigTIFF.
	* coders/tiff.c: Preliminary work to support BigTIFF.

2007-06-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Fix problems encountered when reading and writing
	from/to pipes or compressed files.

2007-06-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (ReadDPXImage): Improved the pixel data marshalling
	in order to obtain better read performance for 10-bit DPX.
	* magick/blob.c (OpenBlob): Added support for MAGICK_MMAP_READ and
	MAGICK_MMAP_WRITE environment variable options to enable input and
	output file access using mmap().

2007-06-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/blob.c (OpenBlob): Disable reading input files using
	memory mapping since it has been learned that some operating
	systems fail to do read-ahead on network files.  Without

	was not being properly checked due to a typo.  The memory limit
	was being tested instead.
	* coders/tiff.c (ReadTIFFImage): Use libtiff to decode OJPEG
	compressed files into RGB.  Probably requires new OJPEG
	implementation from Joris Van Damme which is new in libtiff and
	not yet released. I am not completely sure that this approach is
	correct yet.

2007-05-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	supporting 10 bit samples.

2007-05-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jpeg.c (ReadJPEGImage): Fix reading 12-bit grayscale

	* coders/art.c, coders.cut.c, coders/mat.c, coders/wpg.c: Add
	support for PingImage() so that image identification is fast by
	default.  Also eliminates error message produced by mat.c due to
	rotating an image which has no pixel cache.

	"Fix includedir variable in pkg-config files".
	* magick/pixel_cache.c (GetOnePixel): Fix for SourceForge bug id
	1572357 "GetOnePixel definition appears incorrect".  It is true
	that this function is intended for read-only purposes and that the
	PixelPacket value is returned directly.
	* coders/pdf.c (WritePDFImage): Fix for SourceForge bug id 1510075
	"Failed to write PDF with JPEG compression".
	* magick/command.c (MogrifyImageCommand): Properly bubble up
	errors and terminate further mogrify processing immediately. This
	in response to SourceForge bug id 1391421 "problem doing resize on
	273x1 JPEG".
	* magick/magick.c (InitializeMagickClientPathAndName): Fix for
	SourceForge bug id 1315109 "segfault in InitializeMagick(NULL)".

	format.

2007-03-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (WriteDPXImage): Set DPX reference high quantity to
	2.047 rather than 2.048 since zero is assumed to occupy one count
	and 2.047 seems to be the convention even though the DPX
	specification says the default is 2.048.  Technicolor uses 2.047.
	* m4/acx_pthread.m4: Update version of ACX_PTHREAD macro used.

2007-03-28  Fojtik Jaroslav  <fojtik@humusoft.cz>
