2009-12-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/unix_port.c (MagickSpawnVP): Remove unneeded new line
	character in error message format.

	* Magick++/Makefile.am: Allow Magick++ to be built as a shared
	library under MinGW and Cygwin.  This requires a modern GCC in
	order for C++ exceptions to work.

	* utilities/tests/annotate.sh: MSYS is garbeling up draw command
	so use a command file rather than using command line.

	* coders/{fits.c,meta.c,locale.c}: Fix benign warnings noticed
	under Cygwin 1.7.

	* magick/{constitute.c,resource.c,utility.c}: Fix benign warnings
	noticed under Cygwin 1.7.

2009-12-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/module.c (DestroyModuleInfo): If the Jasper library is
	used, then we can't invoke lt_dlexit() because this unloads the
	Jasper library and Jasper sometimes registers an atexit() cleanup
	handler.  Unfortunately, this may annoy memory leak checkers.

	* coders/jp2.c: Defer Jasper initialization to point of use.

2009-12-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c (MagickCdlImage): New method to apply the ASC
	CDL to an image.
	(MagickHaldClutImage): New method to apply a Hald CLUT to an image.

2009-12-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/studio.h atof(), atoi(), and atol() are legacy functions
	which might not be thread safe, might not enforce reasonable
	limits, and should not be used for new code.  So we implement them
	via strtod() and strtol().

2009-12-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c (MagickGetImageBoundingBox): New method to
	return the crop bounding box required to remove any solid-color
	border from the image.
	(MagickGetImageFuzz/MagickSetImageFuzz): New methods to get and
	set the color comparison fuzz factor

	* wand/pixel_wand.c (ClonePixelWand): New method to deep-copy an
	existing pixel wand.
	(ClonePixelWands): New method to deep-copy an array of existing
	pixel wands.

	* wand/magick_wand.c (MagickSetResolution): New method to set the
	wand resolution.  This one also works before the image has been
	read (unlike MagickSetImageResolution()).
	(MagickSetResolutionUnits): New method to set the wand resolution
	units.  Use in conjunction with MagickSetResolution().  This one
	also works before the image has been read (unlike
	MagickSetImageUnits()).

2009-12-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Magick++/demo/demo.cpp (main): Stop using deprecated functions.

	* wand/drawtest.c: Stop using deprecated functions.

2009-12-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/module.c (ModuleAliases): J2C is supported by the JP2
	coder.

	* coders/jp2.c: JP2 is now an alias for JPC since many files use
	that extension.  Problem reported by Stefano Acerbetti.

2009-12-09  Glenn Randers-Pehrson <glennrp@simple....>

	* coders/png.c: The png8 encoder would fail when trying to write
	a 1-color image.  Problem reported by Bob Clark.

2009-12-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Define _GNU_SOURCE and _NETBSD_SOURCE so that
	pwrite() and pread() prototypes are available under GNU Linux and
	NetBSD.

	* coders/tiff.c: Warnings reduction.

	* magick/widget.c: Warnings reduction.

	* magick/segment.c (Classify): Warnings reduction.

	* magick/magic.c (struct StaticMagic): Length and offset can never
	be negative so use an unsigned type rather than size_t.

	* magick/render.c (TracePath): Fix access one beyond the end of
	the points array.

2009-11-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/gem.c (GetOptimalKernelWidth1D, GetOptimalKernelWidth2D):
	In the Q32 build, convolution kernel size was estimated
	incorrectly for large sigmas on 32-bit systems due to arithmetic
	overflow.

2009-11-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/effect.c (ConvolveImage): Moved here from fx.c since this
	is a more suitable place for it to be.

	* magick/enhance.c (GammaImage): Improve performance a bit.
	Preserve full precision in Q32 build.

2009-11-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/{channel.c,constitute.c,nt_base.h}: Start using the C'99
	`restrict` keyword.

2009-11-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c (MagickGetImageAttribute): New method to get
	an image attribute.  Patch contributed by Mikko Koppanen.
	(MagickSetImageAttribute): New method to set an image attribute.
	Patch contributed by Mikko Koppanen.

	* magick/constitute.c (ReadImage): Log subimage and subrange.

	* configure: Update to Autoconf 2.65.

	* magick/attribute.c (GenerateIPTCAttribute): Returned IPTC string
	values were one character too short.

2009-11-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (AllocateImage): The documented shorthand for
	specifying image size via filename[WIDTHxHEIGHT] was not working
	for raw formats which use the image tile_info data.

2009-11-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (ParseSubImageSpecification): Try to match
	behavior of previous sub-image specification parser.  Some
	incantations did not produce the same results.

	* win2k/IMDisplay/res/{IMDisplay.ico, IMDisplayDoc.ico}: Replaced
	with GraphicsMagick icon prepared by Jaroslav Fojtik.

	* coders/svg.c (ReadSVGImage): Use runtime initialization of
	SAXModules rather than static initialization.

	* magick/command.c: Commands now support reading an image from
	stdin in conjunction with a subrange specification (e.g. "-[1]").
	Problem was reported by Mario Becroft.

	* magick/common.h: New header file to incorporate the common bits
	shared by studio.h and api.h.

	* ltdl/ltdl.c: Update libltdl to 2.2.6b in order to fix security
	issue.  Resolves CVE-2009-3736 as it pertains to GraphicsMagick.

2009-11-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/constitute.c (ConstituteImage, DispatchImage): `A` and
	`T` should indicate transparency and `O` should indicate opacity.
	Behavior was inconsistent.  In some cases `O` meant transparency
	while in other cases it meant opacity. Also, in a few cases, matte
	was not getting enabled in the image as it should.  Problems were
	reported by Scott Kuhl.

2009-11-10  Glenn Randers-Pehrson <glennrp@simple....>

	* coders/png.c: Also suppress new pedantic warnings from most
	older libpng-1.4.0 betas.

	* coders/png.c: Added a warning when attempting to use libpng-1.4beta
	older than 1.4.0beta67.

2009-11-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (MogrifyImage): Only invoke ProfileImage() if
	an ICC CMS transform is to be performed.  Otherwise invoke
	SetImageProfile() to add the new profile.

	* magick/profile.c (ProfileImage): Improve logging messages.

	* coders/tiff.c (ReadTIFFImage): Allow CIELAB TIFF to be read.

	* coders/jpeg.c (ReadJPEGImage): Detect and apply colorspaces
	appropriately for ITU FAX JPEG.

2009-11-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tiff: Updated to libtiff 3.9.2.

2009-11-08  Glenn Randers-Pehrson <glennrp@simple....>

	* coders/png.c: Suppress new pedantic warnings from libpng
	version 1.2.41 and 1.4.0 and later.

2009-11-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* doc/options.imdoc: Document difference between -recolor and
	Adobe Flash color matrix.

2009-11-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (MogrifyImageCommand): Convolve does not accept
	an argument which looks like a geometry.  Resolves SourceForge
	issue #2890923 "Different handling of -convolve between convert
	and mogrify".
	(MogrifyImage): Validate that user-provided matrix is square when
	parsing -convolve and -recolor commands in order to avoid a core
	dump.

	* coders/tiff.c (ReadTIFFImage): Improved/added more coder logging
	statements.

	* magick/xwindow.c: Reflowed some code and comments.

	* magick/utility.c (SetClientName): Default client name does need
	to be "Magick", so original value is restored.

	* coders/mpc.c (ReadMPCImage): is_monochrome and is_grayscale
	flags were not managed properly for the MPC coder.

2009-10-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jpeg.c (ReadJPEGImage): Added jpeg:block-smoothing and
	jpeg:fancy-upsampling defines to control these JPEG library
	options.

	* magick/image.c (SetImageInfo): Fix lockup due to hanging in loop
	while parsing malformed sub-image specification (SourceForge issue
	2886560).  Also fixes the ability to pass the image size via the
	filename specification like "myfile.jpg[640x480]" rather than
	needing to use -size.

	* coders/jpeg.c (ReadJPEGImage): Fix image scaling when used with
	IJG JPEG library version 7.

2009-10-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/resource.c: Added support for a "Threads" limit, which
	specifies how many threads may be used.  Note that if
	omp_set_nested(true) is used, GCC's GOMP seems to replicate this
	number of threads for each level of threading rather than sharing
	the specified number of threads across all teams.  For example,
	specifying four threads leads to sixteen active threads with
	omp_set_nested(true) and nested threading.  This GOMP behavior
	does not seem to cause any harm.
	(GetMagickResourceLimit): New accessor function to retrieve the
	maximum limit for a resource.

	* magick/module.c (ReadModuleConfigureFile): Default set of module
	aliases is now statically initialized.  The modules.mgk file is
	now optional and can be used to support adding more modules, or
	diverting existing format support to a user-provided module.

	* magick/magick.c (DestroyMagick): Document that this function
	should be invoked from the program's primary thread after any
	threads using GraphicsMagick have terminated.
	(GetMagickInfo): Was thread safe for access but not properly
	thread safe during initialization.  Is now fully thread safe.
	(InitializeMagick): Fully initialize everything needed to
	read/write files.  Document that this function MUST be invoked
	from the program's primary thread prior to using any other
	GraphicsMagick functions.

	* magick/color_lookup.c (ReadColorConfigureFile): The colors.mgk
	is now optional so don't throw an exception if it is not found.

	* magick/semaphore.c (AcquireSemaphoreInfo): Deprecated this
	internal function.  Use AllocateSemaphoreInfo() and
	LockSemaphoreInfo() instead.
	(LiberateSemaphoreInfo): Deprecated this internal function.  Use
	UnlockSemaphoreInfo() instead.

2009-10-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* config/colors.mgk: Colors.mkg is now empty since it is used to
	modify or extend the built-in color lookup table.

	* magick/{constitute.c,delegate.c,log.c,magic.c,magick.c,tempfile.c}:
	Explicitly initialize semaphores via InitializeMagick().

	* magick/type.h: New header file to contain types and function
	prototypes for functions in type.c.

	* magick/color_lookup.c (ReadColorConfigureFile): Store RGB color
	table in a static struct.  Entries in the colors.mgk file are now
	used to modify statically-defined entries, or add new definitions
	to the color table.

2009-10-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: --enable-libtool-verbose configure option is no
	longer needed now that we have silent build capability.

2009-10-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/attribute.c (GenerateEXIFAttribute): Add support for
	retrieving GPS EXIF attributes.  Based on work contributed by
	Jukka Manner.

	* Magick++/lib/STL.cpp, Magick++/lib/Magick++/STL.h (shadeImage):
	ShadeImage was the result of a botched cut-and-paste.  Corrected
	now.  Thanks to Jukka Manner for making me aware of this.

2009-10-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/analyze.c: New source file to contain image analysis
	functions.  Moved functions from image.c and color.c to this file.

	* magick/color_lookup.c: New source file to contain color lookup
	functions.  Moved associated functions from color.c to this file.

	* magick/ImageMagick.rc: Remove inclusion of magic.mgk.

	* magick/utility.c (MagickRoundUpStringLength): Use a bit less
	memory.

	* magick/color.c: Use most efficient string allocation function.

	* config/Makefile.am: Eliminate use of magic.mgk.

	* magick/magic.c: Store file header magic data in a static struct.

2009-10-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/describe.c (DescribeImage): Include composition operator
	in verbose output.  Also use CompressionTypeToString() to convert
	a compression enum to a string.

2009-10-11  Toby Thain  <qu1j0t3@users.sourceforge.net>

	* coders/psd.c: Further fix for 2783535 reported by Daniel Kirsch.
	Omit 0x0 layers from the image list, or they break compositing.

2009-10-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/xwindow.c: Check for overflow on all array allocations.

	* magick/command.c (MogrifyImages): If there is only one image in
	the list, then -flatten does nothing at all.

	* magick/transform.c (FlattenImages): If the user provides only
	one image then return a clone of that image rather than reporting
	an error.

	* magick/texture.c (TextureImage): If an under-texture is applied,
	then remove the matte channel.

	* magick/xwindow.c (MagickXMakeImage): Apply a checkerboard
	pattern when displaying non-opaque TrueColor images.  Fix a second
	integer overflow issue related to CVE-2009-1882.

2009-10-10  Toby Thain  <qu1j0t3@users.sourceforge.net>

	* coders/psd.c: Fix for 2783535 reported by Daniel Kirsch. PSD
	parser was confused by 0x0 pixel layers, resulting in image data
	corruption of all following layers.

2009-10-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/xwindow.c (MagickXMakeImage): Fix for CVE-2009-1882
	"Integer overflow in the XMakeImage function".  The problem is
	that the shared memory segment allocated may be smaller than the
	image size requires due to integer overflow.  On some systems it
	may be possible to crash GraphicsMagick (while displaying an image
	file) but not likely to overwrite the heap since shared memory
	segments are outside of the heap allocation.

	* magick/memory.c (MagickMallocArray): Use MagickArraySize().

	* magick/memory.c (MagickArraySize): New private function to
	compute the size of an array and return zero if it overflows the
	size_t type.

2009-10-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dcm.c (ReadDCMImage): Handle (UN)known type VRs correctly
	and interpret the transfer syntax correctly.  Added define
	"dcm:avoid-scaling" to request that the coder should not scale
	image samples unless necessary (i.e. when bits used > quantum
	depth or maximum colormap depth, depending on image type).  Work
	is contributed by John Sergeant.

2009-10-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/Makefile.am (CHECK_PDF_FILE_COMPRESS): Add PDF tests with
	the various compression options.

	* coders/pdf.c (WritePDFImage): If the input file used JPEG
	compression and has not been converted to a bilevel or palette
	image, then use JPEG compression with original settings.  Problem
	was reported by Marco Atzeri.

2009-10-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* config/modules.mgk: DCRAW module entries were missing.

	* coders/tiff.c (WriteGROUP4RAWImage): Was not working properly on
	big-endian CPUs with libtiff 1.4.

	* coders/ps2.c (WritePS2Image): Use ImageToJPEGBlob().

	* coders/ps3.c (WritePS3Image): Use ImageToJPEGBlob().

	name.

	* coders/cals.c (ReadCALSImage): Fix bug in CALS reader which
	caused reading images taller than the image width to fail with an
	error.

	* magick/utility.c (AcquireString): Minor optimizations.
	(AllocateString): Minor optimizations.
	(CloneString): Minor optimizations.
	(LocaleCompare): Minor optimizations.
	(SubstituteString): Re-implemented in a more compact way which
	might avoid some reallocations.

	* magick/magick.c (ListModuleMap): Don't crash if `module` was not
	set.

	* magick/delegate.c (ListDelegateInfo): Fix insignificant memory
	leak.

	* magick/compress.c (ImageToJPEGBlob): Preserve JPEG settings if
	feasable.

2009-09-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/pdf.c (WritePDFImage): Use ImageToHuffman2DBlob() and
	ImageToJPEGBlob().

	* coders/cals.c (WriteCALSImage): Use ImageToHuffman2DBlob().

	* magick/compress.c (ImageToHuffman2DBlob): New private
	convenience function to produce a CCIT Group4 blob.
	(ImageToJPEGBlob): New private convenience function to produce a
	JPEG blob.

2009-09-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jp2.c (ReadJP2Image): Fix scaling problem noticed when
	reading 12-bit JP2 format.  Problem was reported by Steve Shaw.
	(WriteJP2Image): Support writing JP2 files with arbitrary depth
	ranging from 2 to 16 rather than just 8 or 16.

2009-09-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/unix_port.c (MagickGetMMUPageSize): Cache returned page
	size to eliminated repeated system calls.

	* magick/operator.c (QuantumOperatorRegionImage): Fix missing
	percent in progress monitor message.

2009-09-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/meta.c (GetIPTCStream): Should return IPTC block length
	rather than remaining blob length.  Patch submitted by John
	Sergeant.

2009-09-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/meta.c (GetIPTCStream): IPTC blobs should be padded to an
	even size.  Patch submitted by John Sergeant.

2009-09-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (WriteGROUP4RAWImage): Added a GROUP4RAW encoder.

	* coders/cals.c (Huffman2DEncodeImage): Fix test failures when
	doing I/O to an in-memory blob.

	* coders/pcl.c (WritePCLImage): Use a different control code to
	(hopefully) eject the page.  Patch submitted by John Sergeant.

2009-09-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/Makefile.am: Add CALS tests.  Skip testing deep images for
	most formats which don't support deep images.

	* coders/cals.c: CALS module was not being built under Windows
	with MSVC.  Now it is.

	* VisualMagick/configure/configure.cpp (process_library): CALS
	module is dependent on TIFF library.

	* coders/cals.c (WriteCALSImage): Allow CALS writing at any time,
	but only enable CALS reader if libtiff is present at build time.

	* coders/{cals.c,pdf.c,ps2.c,ps3.c} (Huffman2DEncodeImage): Force
	TIFF image type to bilevel type.

	* config/modules.mgk, VisualMagick/bin/modules.mkg: CAL-->CALS
	rather than CALS-->CAL.

2009-09-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/benchmarks.rst: Updated GraphicsMagick vs ImageMagick
	benchmark results.

2009-09-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/msl.c, doc/conjure.imdoc: Add support for a new `profile`
	command in MSL/conjure which applies, adds, or removes one or more
	IPTC, ICC or generic profiles from a file.  Work contributed by
	John Sergeant.

2009-09-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/nt_base.c (NTGhostscriptFind): Make sure we close the
	registry key.  Log any Windows error messages.

	* magick/profile.c (AppendImageProfile): New function to add or
	append a profile.  If the profile already exists, then the data
	provided is appended to it.

	* coders/jpeg.c (ReadGenericProfile,ReadICCProfile,ReadIPTCProfile):
	Profile chunks need to be concatenated.  Otherwise "chunked"
	profiles become corrupted.

2009-09-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/average.c (AverageImages): Moved from image.c to new
	average.c file.

	gradient.c source file.

	* magick/texture.c (ConstituteTextureImage,TextureImage): Moved to
	new texture.c source file.

	* coders/svg.c (ENABLE_SVG_WRITER): Disable SVG writer by default
	since it usually does not work correctly and is unlikely to work
	correctly any time soon.

2009-09-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/profile.c (ProfileImage): GlobExpression is case
	sensitive so assure that its glob strings are always upper-cased.
	Without this fix, lower-cased arguments like "icm" would fail to
	be removed.  This would not be much of a problem except that the
	documentation claims that lower-case works.
	(SetImageProfile): Assure that profile names are upper-cased.

	* magick/fx.c (ColorMatrixImage): Add opaque opacity channel if
	image currently lacks an opacity channel but the matrix updates
	the opacity channel.  Requested by Kerry Panchoo.

2009-09-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/meta.c (GetIPTCStream): Updates from John.Sergeant to fix
	issues with IPTC record 2 blocks and to deal better with IPTC
	embedded in an 8BIM profile.

	* PerlMagick/t/read.t: Added tests for Topol format.

2009-09-12 Fojtik Jaroslav  <JaFojtik@seznam.cz>
	* coders/topol.c: Pallette overflow fixed for subtype 3.

2009-09-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* utilities/tests/msl_composite.sh: Use a draw command file for
	this test script too.

	* utilities/tests/{black-threshold.sh,draw.sh,recolor.sh,
	white-threshold.sh}: MSYS is sometimes wreaking havoc on arguments
	with spaces in them so use work-arounds.

2009-09-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/nt_base.c (NTGhostscriptFind): Improve logging messages
	when searching for Ghostscript.

2009-09-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/pixel_cache.c (CacheInfo): Add read_only member to
	indicate if cache is allowed to be modified.
	(ModifyCache): Clone cache if origin cache is read only.
	(PersistCache): Persistent caches which are attached are treated
	as read-only.  This avoids crash with MPC images which are read
	and subsequently modified.
	Reverted pixel cache locking changes which were made yesterday
	since I decided that they were too risky until file handle
	management is addressed.

2009-09-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/resource.c (InitializeMagickResources): Increase
	operating system file handle limits if necessary.

	* magick/pixel_cache.c: Pixel cache file locking is now done at
	point of access.

	* magick/nt_base.c (NTGhostscriptFind): New function to find
	Ghostscript under Windows, replacing previous Ghostgum
	implementation.

	* Copyright.txt: License is now based on MIT license exactly,
	without extra edits.  Ghostgum code has been eliminated so it is
	no longer necessary to include its license.

2009-09-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/delegate.c (GetPostscriptDelegateInfo): Add a gs-palette
	delegate entry in order to force Ghostscript to output a
	colormapped image if `-type palette` is specified prior to the
	input filename.  Ghostscript's dithering is much courser than
	GraphicsMagick's -colors default (more similar to
	-ordered-dither), but it is fast and produces smaller intermediate
	files.

	* coders/ps.c (ReadPSImage): Eliminate use of NULL pointer when
	progress monitor is enabled.  Was referring to image->filename
	rather than image_info->filename as it should have.

	* magick/delegate.c (InvokePostscriptDelegate): Added an
	`exception` argument so that failure details can be returned.
	Tried to reorganize the code so that it is more tolerant of errors
	such as a dynamically-loadable DLL failing to load.  On POSIX
	systems, Ghostscript was not being invoked as securely as
	expected.

	* coders/Makefile.am: Only build the DPS module if the Display
	Postscript library is available.

	* coders/ept.c (ReadEPTImage): If we don`t have the Display
	Postscript library, then don't try to use it as a fallback.

	* coders/ps.c (ReadPSImage): If we don't have the Display
	Postscript library, then don't try to use it as a fallback.

	* magick/blob.c (CloseBlob): If blob was never allocated, then
	don't try to close it.

2009-09-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/index.rst: Mention 1.2.8 release.

2009-09-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Magick++: New Image methods cdl(), colorMatrix(), and haldClut()
	added.

2009-09-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/shear.c (IntegralRotateImage): Select tile sizes in a
	more intelligent fashion.

	* magick/pixel_cache.c (GetPixelCacheInCore): New private pixel
	cache method to see if image pixels are in core.

2009-09-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/constitute.c (ReadImage): No longer clear the exception
	at the start of ReadImage() and other similar functions.  If the
	user of the function cares, she can clear the exception in
	advance.  It is not right to overwrite exceptions which might not
	have been reported/handled yet.

	* magick/shear.c (IntegralRotateImage): Rotate by zero degrees
	does not need to do any work.

	* coders/*.c, magick/*.c: Include image dimensions in progress
	monitor output when loading or saving a file.  Eliminate redundant
	text from progress messages.

2009-08-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/wmf.c: Eliminate memory leaks.

	* magick/render.c (DrawDashPolygon): Avoid access beyond end of
	array.  Resolves SourceForge issue 2832125 "Crash on SVG
	conversion".

	* coders/png.c (ReadOnePNGImage): Ensure that opacity channel is
	properly initialized.  Resolves SourceForge issue 2831240
	"Possible alpha channel issue with PNG w/palette and tRNS".

2009-08-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/nt_base.h (HAVE_TIFFSWABARRAYOFTRIPLES): Need to define
	this since libtiff includes this function now.

	* VisualMagick/tiff/libtiff/tiffconf.h.in: Enable all the options
	by default.

	* tiff: Updated to libtiff 3.9.1.  3.9.0 was broken.

2009-08-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/profile.c (MagickFreeCMSTransform): Add a CMS transform
	destructor since otherwise Visual Studio does not like it.

	* tiff: Updated to libtiff 3.9.0.

2009-08-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (TimeImageCommand): Add a simple `time`
	sub-command to time the execution of any other GraphicsMagick
	sub-command.  Similar in concept to the `benchmark` sub-command
	but produces output similar to the `time` command offered by the
	zsh command shell.  Handy for when `time` is not available, or
	consistent output is desired.

	* magick/magick.c (MagickGetFileSystemBlockSize): New private
	function to allow getting desired filesystem block size.
	(MagickSetFileSystemBlockSize): New private function to allow
	setting desired filesystem block size.

	* magick/pixel_cache.c (WriteCacheIndexes, WriteCachePixels):
	Temporarily disable pixel cache row coalescing when writing to
	disk until we come up with a good way to optimize write sizes.

	* coders/meta.c (ReadMETAImage): Fix memory leak of profile blob.

2009-08-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* utilities/tests/icc-transform.sh: Add a sanity-test for applying
	ICC profiles.

	* magick/profile.c (ProfileImage): Improve OpenMP performance.

2009-08-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/render.c (DrawPolygonPrimitive): Drawing of points,
	lines, and polygons is now accelerated using OpenMP with good
	speed-up.

2009-08-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/drawing_wand.c (DrawClearException): New function to clear
	drawing wand exception.
	(DrawGetException): New function to retrieve information regarding
	the last drawing wand exception (if any).
	(DrawRender): DrawRender() is now deprecated since it requires an
	Image pointer to be embedded in the drawing wand.  The image
	passed is subsequently lost by CloneDrawingWand() since it must
	clone the image using copy-on-write.  Subsequent use of
	DrawRender() on a cloned wand scribbles on an image the user does
	not have access to.  Use existing Wand function MagickDrawImage()
	instead.
	(DrawAllocateWand): DrawAllocateWand() is now deprecated since it
	requires passing an Image pointer into the drawing wand.  Use
	existing DrawingWand function NewDrawingWand() instead.

2009-08-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/drawing_wand.c (CloneDrawingWand): New function to
	deep-copy a drawing wand.
	(NewDrawingWand): Use a boolean flag to track if image is
	allocated by the wand, or by the user.  Most of the previous
	DrawAllocateWand() code is moved into NewDrawingWand() so that the
	boolean flag is easy to manage.

2009-08-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (WriteTIFFImage): Support writing grayscale
	JPEG-compressed TIFF.

2009-08-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (ReadTIFFImage): Don't override the photometric
	for grayscale JPEG-compressed TIFF.

2009-08-08  Glenn Randers-Pehrson <glennrp@simple....>

	* coders/png.c: Made compatible with libpng-1.4.0beta74 and later
        (won't work with libpng-1.4.0beta35 through beta73) due to change
        in names of png_struct members "trans" and "trans_values"). 

2009-08-08 Fojtik Jaroslav  <JaFojtik@seznam.cz>
	* coders/topol.c: Pallette is ignored for subtype 5 (RGB).

2009-08-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/{cineon.c, dpx.c, locale.c, svg.c}, magick/{attribute.c,
	effect.c, utility.c}: Eliminate warnings reported by GCC 4.4.0.

2009-07-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Try to be more insistent about compilation failure
	if libjpeg version is less than 6b.  IRIX compiler only warns
	about #error preprocessor statement.

2009-07-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c (MagickSetCompressionQuality): New Wand
	method to allow setting the compression quality.

2009-07-29 Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/topol.c: Fixed missing break. Added response to ping.

2009-07-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/pcx.c (ReadPCXImage): Detect improper rows, columns, or
	depth.  Fixes CVE-2008-1097 "Memory corruption in ImageMagick's
	PCX coder".

	* configure.ac: Update to Autoconf 2.64.

2009-07-25 Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/topol.c: Fixed several issues. Added possibility to read
	TopoL level 2 images.

2009-07-25 Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* VisualMagick\configure\configure.cpp: Fixed library absolute path issue.

2009-07-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/random.c (DestroyMagickRandomGenerator): Trick to free
	thread specific random kernel contexts simply locks up with MSVC's
	OpenMP, so remove this functionality.

2009-07-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/random.c (DestroyMagickRandomGenerator): Cleanup thread
	specific random kernel data.

	* magick/tsd.c (MagickTsdKeyCreate): Fix glitch when built without
	any threads support.

2009-07-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

2009-07-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* png: Updated libpng to 1.2.38.

2009-07-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (GetImageInfo): Default interlace for ImageInfo
	is now UndefinedInterlace so that it is possible to preserve the
	original interlace setting for the image file.  Code depending on
	the previous default setting of NoInterlace is adjusted to suit.
	This is a potentially risky change given the brittle nature of
	some of the legacy code.

	* coders/tiff.c (ReadTIFFImage): Stripped reader needs to read
	planar TIFF plane-wise in order to work with libtiff's internal
	buffering.
	(ReadTIFFImage): Tiled reader needs to read planar TIFF plane-wise
	in order to work with libtiff's internal buffering.
	(WriteTIFFImage): Tiled writer needs to output planar TIFF
	plane-wise in order to work with libtiff's internal buffering.

2009-07-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	with actual montage options.

2009-07-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (WriteTIFFImage): Allow the user to be able to
	specify rows_per_strip when using JPEG compression.  The
	rows_per_strip value rounded up to the nearest multiple of 16.

2009-07-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (WriteTIFFImage): Add the ability for the user to
	manually specify the predictor using syntax like `-define
	tiff:predictor=2`.

2009-07-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/quantize.c (QuantizeImages): Avoid crash when using
	-monitor +map on an image list.

	* magick/command.c (BenchmarkImageCommand): Send benchmark report
	to stderr so that it does not interfer with pipes.

	* magick/cdl.c (CdlQuantum): Add range limiting of value before
	applying power function.

	* coders/dpx.c (ReadDPXImage, WriteDPXImage): Using floating point
	calculations when building sample value lookup tables in order to
	decrease error.  In particular input values were being scaled too
	low, resulting in improperly rounding down during processing of
	the image.

2009-07-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/pdf.c (WritePDFImage): Incorporated updates from John
	Sergeant to remove the font and thumbnail objects from PDF output.

2009-07-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/cdl.c (CdlImage): New function to apply an ASC CDL
	transform to the image.  Original implementation by Clément Follet
	from Workflowers but considerably re-worked by Bob Friesenhahn.

	* coders/dcm.c: Eliminate compiler warnings.

2009-07-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dcm.c: Significant re-write of the DICOM reader.  Work
	contributed by John Sergeant.

2009-07-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/blob.c (OpenBlob): Subsequent research shows that Direct
	I/O will not be useful to ordinary file I/O due to specific
	requirements for buffer alignments and I/O sizes.  Support for
	requesting it is removed.

2009-07-01  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* www/formats.rst: ART module has writer for more than year.
	So mark this here.

2009-06-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac, magick/blob.c: Add experimental Solaris direct I/O
	support which is enabled by setting the environment variable
	MAGICK_DIRECTIO to TRUE.  Direct I/O bypasses the filesystem
	cache.  Only works for NFS and UFS, and not for ZFS.

2009-06-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* rungm.sh.in: Fix environment variable issues noticed while
	running the test suite under MinGW.

	* magick/command.c (MogrifyImageCommand): Cache mogrify argument
	images so that they are only loaded once when mogrify is used to
	process multiple image files.

	* coders/dpx.c (WriteDPXImage): Fix leak of chroma image when
	subsampling to 4:2:2.

2009-06-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/magick.c (InitializeMagick): Invoke InitializeMagickRegistry().

	* magick/registry.c (RegistryInfo): There is no reason to expose
	the RegistryInfo structure in the public interface so it is moved
	to registry.c.
	(InitializeMagickRegistry): Add a function for initializing the
	magick registry.

2009-06-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (CompareImageCommand): Report full error rather
	than rounded error in error reports since sometimes the value
	reported was rounded down to zero.

	* utilities/tests/hald-clut-transform.sh: New test to verify that
	Hald CLUT interpolation is working perfectly.

	* utilities/tests/hald-clut-identity.sh: Renamed from
	hald-clut.sh.

	* coders/jpeg.c (RegisterJPEGImage): Fix typo which caused IJG
	library version to be shown for "JPG" format but not for "JPEG".
	Also use a more descriptive name for JPEG library.

	* magick/image.c (DescribeImage): Filter out spurious EXIF
	attributes which already exist because we previously accessed
	them.  We do a full EXIF dump later.

2009-06-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/FAQ.rst: Add a FAQ about how to process many files at once.

	image supplied via -mask.

	* utilities/tests/mask.sh: Add a test for applying a mask image
	with -mask.

2009-06-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/attribute.c (GenerateEXIFAttribute): Identify unknown
	tags via their four-character hex value.

	* magick/colorspace.c (CMYKToRGBTransform): Use symbolic notation
	to access pixel quantum values.

	* utilities/tests/identify.sh: Added a test for `identify
	-verbose` on a well-populated JPEG file.

	* PerlMagick/t/{jpeg/write.t, jng/read.t, jng/write.t}: Relax
	allowed error for JPEG-related tests.

	* magick/attribute.c (GenerateEXIFAttribute): Attribute allocation
	size was too small causing overrun of memory buffer.  Problem was
	added on 2009-06-08.

	* magick/image.c (AllocateDepthMap): Allocation size was one
	element too small.
	(GetImageDepth): Forgot to free depth map.  Memory leak of 64K
	bytes per iteration.

	* coders/{mat.c, miff.c, pdf.c, ps3.c}: Have Zlib use our memory
	allocators.

	* magick/memory.c (MagickMallocCleared): New memory allocation
	interface which is similar to MagickMalloc() except that returned
	memory has been cleared first.

	* magick/hclut.c (HaldClutImagePixels): Fix wrong accesses
	detected by valgrind.  Also improve execution performance.

	* coders/xwd.c (WriteXWDImage): Fixed valgrind memcheck complaint
	about access to uninitialized data.

2009-06-09  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/txt.c Handle alpha channel for ImageMagick's alternative .txt

2009-06-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

2009-06-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/hclut.c (HaldClutImage): Add a Hald CLUT capability as
	described at http://www.quelsolaar.com/technology/clut.html.  This
	allows a color transformation to be easily created and replicated
	on any number of images.  The algorithm is accessed by the
	-hald-clut option of `convert` and `mogrify`.  The original
	algorithm is by Eskil Steenberg and was adapted for GraphicsMagick
	by Clément Follet from Workflowers with support from Cédric
	Lejeune of Workflowers.

2009-06-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/utility.c (GetMagickGeometry): Support `^` modifier to
	geometry specification which indicates that specified size is a
	minimum bounding box rather than a maximum bounding box while
	preserving the image aspect ratio.

2009-06-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (ReadDPXImage): Diminish compilation warnings.

	* magick/random.c (AcquireMagickRandomKernel): Fix potential
	multi-thread issue detected by valgrind's helgrind tool.

	* magick/magick.c (InitializeMagick): Semaphore subsystem needs to be
	initialized before anything which uses it.

	* magick/semaphore.c (InitializeSemaphore): Since we are using
	PTHREAD_MUTEX_INITIALIZER to initialize primary POSIX mutex in the
	semaphore subsystem, we should not explicitly initialize the
	semaphore a second time.

	* magick/segment.c (Classify): Fix multi-thread issue detected by
	valgrind's helgrind tool.

	* magick/render.c (DrawAffineImage): Use InterpolateViewColor() to
	evalute a bi-linear interpolated point rather than obtaining a
	pixel value from a close pixel.  This provides better results.

2009-06-02  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/txt.c Attempt to handle alpha channel.

2009-06-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/pixel_cache.c (InterpolateViewColor, InterpolateColor):
	Moved from gem.c.  Gem functions should not be accessing the pixel
	cache.

2009-06-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (CompareImageCommand): Add a -maximum-error
	option to `compare` so that it can easily be used in boolean logic
	when comparing images.

2009-05-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/Makefile.am (TESTS_XFAIL_TESTS): If Ghostscript is not
	available then XFAIL the tests which depend on it.

	* magick/pixel_cache.c (GetCacheInfo): Assure that allocated
	stuctures do not occupy the same cache lines.

2009-05-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/studio.h (MAGICK_CACHE_LINE_SIZE): Allow cache line size
	to be set in one place in case we want to configure for it later.

	* magick/effect.c (AllocateMedianList): Assure that allocated
	stuctures do not occupy the same cache lines.

	* magick/random.c (AcquireMagickRandomKernel): Assure that
	allocated random kernels do not occupy the same cache lines.

	* magick/gem.c (GenerateDifferentialNoise): User is required to
	supply random kernel.

	* doc/options.imdoc: Document -format "%p".  Problem was reported
	by Stijn Sanders.

2009-05-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/Makefile.am (coders_tiff_la_LIBADD): Libtiff may now also
	depend on libjbig and the math library.

	* doc/gmdoc2html: Fix link to ball.png.  Problem was reported by
	Wes Fox.

	* VisualMagick/installer/inc/files-documentation.isx: Include Wand
	API documentation.

	* VisualMagick/installer/inc/icons-associate.isx: Fix Windows
	Start menu link to web pages.

	* configure.ac: --with-perl is changed to --without-perl since
	building PerlMagick is no longer the default.  Building PerlMagick
	automatically has caused too many problems.

	* PerlMagick/Makefile.am: GraphicsMagick no longer automatically
	installs PerlMagick.  Use the procedure described by
	PerlMagick/README.txt to build and install PerlMagick.

2009-05-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Debian stores Ghostscript fonts under
	/usr/share/fonts/type1/gsfonts so check there for fonts.  Issue
	reported by Ralf Wildenhues.

2009-05-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* PerlMagick/Magick.xs: Fix Ping of blob.

	* PerlMagick/t/ping.t: Added tests for pinging files and blobs.

	* www/perl.rst: Ping blob syntax is like $image->Ping(blob=>@blob).

	* PerlMagick/Makefile.PL.in: Increase the probability of
	PerlMagick build success by using the user-specified C compiler as
	the linker if the C compiler was already used as the linker.  This
	helps if the C compiler used to build GraphicsMagick is a more
	recent vintage than the one used to build Perl.

	* PerlMagick/t/wmf/read.t: Test needs to be more lenient for
	Linux.

	* Makefile.am (TESTS_ENVIRONMENT): Pass a complete text
	environment so that we don't need to execute rungm.sh in order to
	run the test suite.

2009-05-25  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

	* version.sh: Define PACKAGE_STRING.

2009-05-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/tempfile.c (ComposeTemporaryFileName): Use new random
	number generator.

	* magick/random.c: Implement a random number generation system
	based on George Marsaglia's multiply-with-carry generator.
	Somewhat slower than rand() but produces better random numbers
	with a period >2^60.  Suggested by Mark Mitchell.

2009-05-24  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/txt.c Small optimization:

	Before: 2000 iter 34.08s user 34.24s total 58.420 iter/s

	After: 2000 iter 21.55s user 21.76s total 91.891 iter/s

2009-05-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am (XFAIL_TESTS): Handle the case where FreeType is not
	available by marking tests dependent on FreeType as XFAIL.
	(TESTS): Reorder TESTS so that there will be no trailing spaces
	since this confuses certain older versions of GNU make.

2009-05-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/tempfile.c (ComposeTemporaryFileName): Use simpler code
	(suggested by Mark Mitchell) to compute the substitution index.
	(AcquireTemporaryFileDescriptor): Try harder to generate a
	successful temporary file and fall through to alternative
	implementations if the first does not succeed.

	* magick/magick.c (InitializeMagick): Use MagickRandNewSeed() to
	seed the default random number generator.

	* magick/utility.c (MagickRandNewSeed): Include PID in random
	number seed generation.

2009-05-22  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/txt.c Fixed char vs int parameter problem.
        Better detection of too dark 16bit or 32bit images.

2009-05-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am (AUTOMAKE_OPTIONS): Enable parallel-tests and
	color-tests options.  Parallel test execution does not pass tests
	yet.

	* PerlMagick/PerlMagickCheck.sh.in: Run PerlMagick tests via a
	normal check script rather than a check hook.

	* coders/identity.c (ReadIdentityImage): Fix compilation with Sun
	compiler.

2009-05-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/rwfile.c: Allow the user to specify the basename for
	temporary files.

	* tests/Makefile.am: Add a set of TXT read/write tests.  Pass the
	file name specification to use for the rwfile-based tests.

2009-05-21  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/txt.c Fixed endian set to native endian.

2009-05-20  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/txt.c Faster read ImageMagick files.
	Removed BImgBuff=NULL;

	* coders/cals.c (RegisterCALSImage): Consolidate duplicate text
	strings.

2009-05-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/cals.c: Add support for reading CALS type 1 format.
	Contributed by John Sergeant.

	image.

2009-05-19  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/txt.c Ability to read back Q32 txt files.

2009-05-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Support Linux style silent build rules.

2009-05-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am: Updated to Automake 1.11.

2009-05-17  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/txt.c First attempt to read back txt file.
	It is amazingly ineffective, but it seems to work.

2009-05-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/resize.c (HorizontalFilter, VerticalFilter): When
	resizing a non-opaque image, attenuate the influence of
	surrounding colors based on their degree of transparency in order
	to avoid "halos" around objects caused by colors which are
	transparent and therefore not part of the visible image.  Patch
	contributed by Pavel Merdin via SourceForge Tracker #2792322.
	(VerticalFilter, VerticalFilter): Additional clean-up and
	optimizations.

2009-05-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (MogrifyImage): Added a -recolor command option
	to provide access to ColorMatrixImage().

	* magick/fx.c (ColorMatrixImage): New function to apply a color
	matrix similar to Adobe Flash Flash.filters.colorMatrixFilter(),
	and Windows GDI+ ColorMatrix class, (order up to 5x5) to the image
	pixels.

2009-05-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/perl.rst: Add missing PerlMagick debug event types.

	* coders/pcl.c: Major improvements from John Sergeant.  These
	include: 1) Fixed 2 bit output where Max=BLACK - this always
	produced negative images even when -negate was passed as a
	parameter. The code now uses a two element palette to handle this
	situation.  2) Added support for 8 bit pseudoclass images.  3)
	Changed the coder to allow adjoin, placing each sub-image on a new
	page.  4) Added support for compression. Any compression other
	than "None" will cause the coder to to try to calculate and pick
	the best out of the PCL set of RLE, Tiff RLE or delta compression
	on a per row basis, as well as handling repeated rows and zero
	rows intelligently.

2009-05-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* utilities/Makefile.am (MAGICKPROGRAMS): Add a `compare`
	ImageMagick compatibility link.

	checks for external commands.

	* coders/url.c (ReadURLImage): Added access confirmation checks
	for URLs.

	* magick/blob.c: Added access confirmation checks for files.

	* magick/confirm_access.c (MagickConfirmAccess): Added an access
	confirmation facility to allow the API user to monitor and/or
	block access to files and URLs.  This allows the API user to
	implement a security policy based on actual accesses.

2009-05-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* png: Updated libpng to 1.2.35.

	* lcms: Updated lcms to 1.18a.

2009-05-01  Glenn Randers-Pehrson <glennrp@simple....>

	* coders/png.c (WriteOnePNGImage and WriteOneJNGImage): Changed

	confusion with planned new public png:bit-depth attribute.

2009-04-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (MogrifyImages): Deal slightly better with the
	case when MogrifyImage() expands one image into several.  Still
	don't know of a sane way to deal with -crop WIDTHxHEIGHT.

	* magick/transform.c (TransformImage): Image which is updated may
	be a list so account for that.

	* configure.ac: Add a test for the `restrict` keyword so that
	eventually we can use it.

	* coders/jpeg.c (ReadJPEGImage): Tidy JPEG reader by moving JPEG
	properties analysis code into subroutines.

2009-04-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* doc/display.imdoc: Fix documentation for crop and chop keyboard
	accelerators.  Fixes SourceForge bug #2593388 "error in the
	documentation/Keyboard accelarators".

2009-04-20  Glenn Randers-Pehrson <glennrp@simple....>

	* coders/png.c: Cosmetic-only, change `True` to `MagickTrue` or
	`MagickPass` and `False` to `MagickFalse` or `MagickFail`.

	(matte, colors, depth) while writing a PNG.

2009-04-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* doc/options.imdoc: Document the direction of rotation.

2009-04-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/log.c (LogMagickEventList): Use MagickPackageName from
	version.h rather than hard-coding `GraphicsMagick`.

2009-04-18  Glenn Randers-Pehrson <glennrp@simple....>

	* coders/jpeg.c: Fixed a warning about `shadowed` variables.

2009-04-17  Glenn Randers-Pehrson <glennrp@simple....>

	* coders/png.c: Fixed some warnings about `shadowed` variables.

2009-04-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Add tests for some reentrant versions of functions
	where we are still using the non-rentrant versions.

	* magick/composite.c (CompositeImage): Fix problem with
	compositing images where the change image overlaps off the left
	side of the canvas.  Should fix SourceForge issue #2766200 `memory
	allocation error when compositing small images`.

2009-04-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/semaphore.c: Re-arrange ifdefs so that it is possible to
	use pthreads under the WIN32 API.

2009-04-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/bit_stream.c: Bitstream functions were often not inlining
	and inline functions which don't inline are not much use.
	Bitstream functions are now normal library functions.

2009-03-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* VisualMagick/bin/delegates.mgk: Remove bounding box option (-g) from
	Postscript delegate specifications.

	* config/delegates.mgk.in: Remove bounding box option (-g) from
	Postscript delegate specifications.

	* coders/{ept.c, pdf.c, ps.c} : PDF bounding box is sometimes
	incorrect or not globally applicable so don't specify bounding box
	when reading PDF files.  Postscript files do need the bounding box
	so make sure that it is still supplied.  Resolves SF tracker issue
	2487651 `convert from pdf chops off rhs`.

2009-03-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/Magick++/Image.rst: Translate Image.html to reStructuredText
	format for easier maintenance.

2009-03-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	recurring conditional statement.  It turns out that the -endian
	option is working as it should.

2009-03-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/{gray.c, rgb.c, cymk.c}: Work toward supporting the
	-endian option.  Not working properly yet.

	* scripts/format_c_api_doc.py: Now supports --include-rst option.

2009-03-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (GetImageBoundingBox): If we fail to find a
	smaller bounding box, then the returned bounding box is the entire
	image.

2009-02-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* VisualMagick/magick/magick_config.h.in: Provide configuration
	access to the DisableSlowOpenMP define.

	* magick/pixel_cache.c (ModifyCache): Set image `taint` flag and
	clear monochrome and grayscale flags when pixels are accessed
	read/write rather than at sync.

	* coders/Makefile.am (MAGICK_CODER_SRCS): Add coders/hrz.c to
	build.

2009-01-27  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* magick/resize.c (ResizeImage): Make error handling more robust.

	* magick/pixel_cache.c (SetNexus): Return a run-time error to
	invoking code rather than exiting the program if the pixel staging
	buffer fails to be allocated.

	* coders/tiff.c (ReadTIFFImage): Allow the user to force the
	returned image to be TrueColor type for min-is-white and
	min-is-black TIFF files.  Previous to this, bilevel TIFF files
	were always returned as PseudoClass.

2009-01-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/pixel_cache.c, coders/pnm.c: Fix several race conditions
	reported by Julian Seward.

	since a glitch was encountered that needs to be resolved.

	* magick/{channel.c,compare.c,constitute.c,decorate.c,effect.c,fx.c,
	image.c,operator.c,pixel_iterator.c,render.c,resize.c,segment.c,
	shear.c,transform.c}: Use explicit OpenMP critical sections to
	avoid possible cross-contention.

	* coders/{dpx.c, pnm.c} Use explicit OpenMP critical sections to
	avoid possible cross-contention.

2009-01-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	installed as part of the base install or else the modules will
	fail to load.

2009-01-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dib.c (ReadDIBImage): Fix assertion thrown for DIB files

	zip stream is not usable as a file handle.  Switch back to using
	stat instead, but use _stati64 if available.

2009-01-04  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/fits.c: Fixed bug in scene count in extension block.
	* coders/fits.c: Supported logging.

	(OpenBlob): Don't attempt to test header magic on file we are
	writing.  Silly benign bug in obtuse code.

	* coders/tiff.c (ReadTIFFImage,WriteTIFFImage): Strip out use of
