2011-12-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/pixel_cache.c (AcquireCacheNexus):
	MirrorVirtualPixelMethod was broken.

2011-12-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Improve configuration support for Open64 Compiler
	Suite: Version 4.2.5.2 compiler with OpenMP.

	* coders/tga.c (ReadTGAImage): Assume that 32-bit TGA files have
	an alpha channel, even if they are not marked as such.  Fixes
	SourceForge issue 3466908 "TGA with alpha".

	* configure.ac: Revert changeset eaa27346d8e9 which tried to avoid
	the OpenMP library being included multiple times because in some
	cases it is not included at all.

2011-12-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (VersionCommand): For MSVC builds, report if
	SSE or SSE2 was used in the build.

	* Release GraphicsMagick 1.3.13.

	* Update libtiff to release 4.0.0

2011-12-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Update libpng to release 1.5.7

2011-12-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Update lcms2 to release 2.3

2011-12-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Update Automake used to 1.11.2.

2011-12-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/OpenMP.rst: Updated with new results, including 12-core
	Intel Xeon E5649 and 16-core AMD Opteron 6220 "Bulldozer" CPUs.

	* magick/studio.h: Enable building and running correctly with
	Open64 Compiler Suite: Version 4.2.5.2 compiler with OpenMP.

	* magick/command.c (BenchmarkImageCommand): Add -rawcsv option to
	benchmark to output only original data in a CSV format.

2011-12-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Fix various issues noticed when cross-compiling for the
	i686-w64-mingw32 target.

2011-12-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/effect.c (ConvolveImage): For Q8 and Q16 builds use
	'float' rather than 'double' for computations in order to improve
	performance with some compilers.

2011-12-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/effect.c (ConvolveImage): Special-case grayscale images
	for better convolution performance.

2011-12-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (BenchmarkUsage): -stepthreads now requires an
	argument which is the increment (starting at zero) to the number
	of threads for each step.  This hastens benchmarking with a large
	number of cores.

2011-12-07  Glenn Randers-Pehrson  <glennrp@simple...>

	* coders/png.c: Eliminate use of FARDATA.  It's no longer needed
	and will no longer be supplied by png.h in libpng-1.6.0.

2011-12-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (BenchmarkImageCommand): Added Karp-Flatt
	metric to benchmark output.

2011-12-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* GraphicsMagick.spec.in: Eliminate use of deprecated BuildPrereq
	in RPM spec file.

2011-11-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/constitute.c (WriteImagesFile): Should set file in
	ImageInfo based on provided parameter rather than relying on it
	already being set.  File argument was not being used.

2011-11-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: For packed 10 bits, datums are now represented in
	the same (reversed) order for all RGB and YCbCr formats.
	Previously YCbCr 4:4:4 formats were not swapping the word datums
	because the only real-world files encountered did not swap the
	word datums.  Resolves SourceForge bug 2057277 "DPX 10bit CbYCr
	Image seems to be wrong".

	* wand/magick_wand.c (MagickWriteImagesFile): New function to
	append images to a provided file handle.  Resolves SourceForge
	issue 3046868 "added MagickWriteImagesFile".

	* magick/constitute.c (WriteImagesFile): New function to append
	images to a provided file handle.

	* magick/blob.c (OpenBlob): Don't rewind already open file handle
	passed to OpenBlob() since we don't know the intended state of
	this file handle, and because it prevents appending to an existing
	file.  This change is part of the fix for SourceForge issue
	3046868 "added MagickWriteImagesFile".

	* wand/magick_wand.c (MagickSetImageSavedType): New function to
	allow specifying the storage type used when saving the file
	(rather than changing the current image characteristics).
	Resolves SourceForge patch 3110185
	"MagickGetImageSavedType()/MagickSetImageSavedType() API".
	(MagickGetImageSavedType): Return the storage type which will be
	used when the image is saved.

	* magick/annotate.c (RenderFreetype): Add support for drawing text
	using a bitmap font.  Resolves SourceForge patch 3230719 "add
	support for drawing text with bitmap font to annotate.c".

	* magick/profile.c (AppendImageProfile): Don't leak profile buffer
	while appending a chunk to an existing profile.  Resolves
	SourceForge patch 3294496 "Fix a memory leak in
	profile.c(AppendImageProfile)".

2011-11-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (BenchmarkImageCommand): Include the number of
	threads used in the benchmark results output.
	(BenchmarkImageCommand): New benchmark option -stepthreads to
	execute the specified command with an increasing number of threads
	to measure how an algorithm benefits from threading.
	(BenchmarkImageCommand): Fix benchmark argument parsing so it is
	not order dependent.
	(BenchmarkImageCommand): Add a speedup indication to -stepthreads
	output.

	* config/delegates.mgk.in: File names in gnuplot files need to be
	surrounded by double quotes or gnuplot parser will reject them.

2011-11-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/effect.c (GetMedianList): Return PixelPacket via pointer
	rather than by value.

	* version.sh: For snapshots packages, PACKAGE_CHANGE_DATE now uses
	a form like "snapshot-20111121" rather than "unreleased" so it is
	possible to determine the vintage of an installed snapshot.

2011-11-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tga.c (ReadTGAImage): Fix for poor TGA reading
	performance due to excessive use of GetBlobByte().  Performance is
	fixed by adding local buffering.  Fixes SourceForge bug 3439531
	"Slow TGA reading".

2011-11-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/effect.c (AdaptiveThresholdImage): More performance
	improvements.

2011-11-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/analyze.c (GetImageBoundingBox): Add a special case to
	handle absolute color comparison.

2011-11-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* png: Update libpng to 1.5.6 release.

2011-10-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Avoid linker warnings when building GraphicsMagick
	regarding OpenMP library being included multiple times.

2011-10-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	uninitialized data when parsing long format tag length.

2011-10-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/import.c: Move low-level pixel import functions from
	constitute.c to new file import.c.

	* magick/export.c: Move low-level pixel export functions from
	constitute.c to new file export.c.

	* magick/floats.c: Move Richard Nolde's floating point conversion
	functions from constitute.c to new file floats.c.

2011-10-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtool: Updated to libtool 2.4.2.

	* configure.ac: Automake conditional for HasPNG can not itself be
	conditional.  Indent PNG script code appropriately.

2011-10-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am (AUTOMAKE_OPTIONS): Distribute lzma-compressed
	tarball in 'xz' format rather than deprecated 'lzma' format.

2011-10-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Fix syntax error with GSCMYKDevice ('==' rather
	than '=').  Thanks to Glenn Randers-Pehrson for noticing and
	reporting the issue.

2011-10-12  Glenn Randers-Pehrson  <glennrp@simple...>

	* Use a "for" loop in configure.ac to find libpngNN.

2011-10-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/pixel_wand.c (NewPixelWand): Invoke InitializeMagick()
	automatically in case user forgets to do so.

	* wand/drawing_wand.c (NewDrawingWand): Invoke InitializeMagick()
	automatically in case user forgets to do so.

	* wand/magick_wand.c (NewMagickWand): Invoke InitializeMagick()
	automatically in case user forgets to do so.

	* png: libpng sources were updated to release 1.5.4.

2011-10-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (ReadTIFFImage): TIFFGetField() on
	TIFFTAG_OPIIMAGEID was causing a crash due to an argument
	mis-match between GraphicsMagick and libtiff.  Also fixed a few
	GCC 4.6 warnings.  Problem was reported by Dylan Millikin.

2011-10-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c (MagickSetDepth): New function to set the
	depth used when reading from an image format which requires that
	the depth be specified in advance.
	(MagickReadImageBlob): Use BlobToImage() to read the blob.

	* magick/effect.c (AdaptiveThresholdImage): Reduce or eliminate
	expensive floating point calculations when possible.

	* wand/magick_wand.c (MagickSetFormat): New Wand function to allow
	setting the file or blob format before it has been read.

2011-09-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* VisualMagick/installer/inc/tasks-install-perlmagick.isx: Windows
	setup installer now installs PerlMagick built against ActiveState
	Perl v5.12.4 build 1205.

	* magick/annotate.c (RenderFreetype): Eliminate spurious "out of
	memory" exceptions due to empty text string.

2011-09-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	coder.

	* jpeg: Record that jpeg sources were updated to release v8c.

	* lcms: Record that lcms sources were updated to release 2.2.

	* png: Record that png sources were updated to release 1.5.4.

	* tiff: Record that tiff sources were updated to release 4.0.0beta7.

	* xml: Record that libxml2 sources were updated to release 2.7.8.

	* zlib: Record that zlib sources were updated to release 1.2.5.

	* VisualMagick/installer/inc/body.isx: Set MagickConfigDirectory
	for DLL build so that .mgk files are put in application top
	directory.  This makes installation layout between static and DLL
	builds more similar.

2011-08-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/list.c (AppendImageToList): Documentation for
	AppendImageToList() was wrong.  Problem was reported by Brad
	Harder.

2011-08-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/display.c (MagickXMagickCommand): Display 'save' and
	'print' should display useful error details.  Problem was reported
	by Brad Harder.

2011-08-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/semaphore.c (AllocateSemaphoreInfo): Enable pthread mutex
	error checking if MAGICK_DEBUG is defined when the code is
	compiled.  This mode helps validate that mutexes are used
	correctly.  No longer enable recursive mutexes since the
	GraphicsMagick logic should be able to operate without this
	assistance.

2011-08-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dcm.c (DCM_ReadOffsetTable): Fix wrong cast noticed when
	compiling with LLVM.

2011-08-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/enhance.c (LevelImageChannel): Fix documented prototype.
	Problem was reported by Brad Harder.

2011-07-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/pixel_cache.c (AcquireOneCacheViewPixelInlined): Only use
	image colormap if the image storage class is PseudoClass.
	Eliminates a core dump when the image is in CMYK space.

2011-07-20  Glenn Randers-Pehrson  <glennrp@simple...>

	* coders/png.c: account for changed typecast of png_get_iCCP
	argument in libpng15 

2011-07-20  Glenn Randers-Pehrson  <glennrp@simple...>

	* configure.ac: look for libpng15, libpng14, libpng12, and libpng
	in that order.

2011-07-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* png: Update to libpng 1.5.4.

2011-06-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/docutils-articles.css: Style sheet syntax fixes. Patch by
	Mark Mitchell.

	HTML.  Patch by Mark Mitchell.

2011-06-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (SetImageType): Fix documentation for enumeration
	names. The types need "Type" as part of the name.  Problem was
	reported by Brad Harder.

2011-06-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* scripts/html_fragments.py (banner_template): HTML banner
	improvements to go along with style-sheet changes.

	* www/docutils-articles.css: Style-sheet improvements by Mark
	Mitchell to work better on small screens.

2011-06-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/project.rst: Add a page for links to pages about the
	project.  The intention is to use this page to reduce the clutter
	in the banner.

2011-05-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* doc/options.imdoc: Document tiff:group-three-options define.
	* coders/tiff.c (WriteTIFFImage): Add support for a
	tiff:group-three-options define to allow power-users to set the
	value of the GROUP3OPTIONS tag.

2011-05-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/Makefile.am: Include Hg.*, remove CVS.*.

	* scripts/html_fragments.py (nav_template): CVS tab changed to
	Source, which links to Hg.html.

	* www/Hg.rst: Document Hg repository access.

2011-05-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* scripts/rst2htmldeco.py (docutils_opts): Do not include a
	datestamp of any kind since it unnecessarily churns the
	repository, particularly if the output file did not otherwise
	change.

	* INSTALL-unix.txt: Fix typo in description of --without-lzma.

2011-05-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jpeg.c (ReadJPEGImage): Treat exceptions thrown by
	jpeg_finish_decompress() as warnings rather than errors.
	(JPEGErrorHandler): Handle JPEG errors directly rather than
	passing them to a message formatting routine for handling.  Also
	added useful logging.
	(JPEGMessageHandler): Only handle JPEG traces and warnings.  Also
	added useful logging.

2011-05-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jpeg.c (EmitMessage): Treat an unhandled EXP marker as a
	warning rather than a hard error.  Resolves SourceForge issue
	3297995 "Unsupported marker type 0xdf".

2011-05-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (AppendImages): If the input list only contains
	one image, then return a new handle to the one image in the list
	rather than reporting an exception.  Problem was reported by Ravil
	Rakhimgulov ("Hunter1972").

2011-04-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (SetImageColorRegion): New function to set the
	constant pixel color for a specified region of the image.
	(AppendImages): Only color background pixels when needed.

2011-04-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (WriteTIFFImage): Added TIFF writer support for
	JBIG1 compression.  Not proven to work yet.

	* magick/image.h (CompressionType): Added Group3Compression as an
	alias for already existing FaxCompression.  Added
	JPEG2000Compression, JBIG1Compression, and JBIG2Compression for
	future use.

2011-04-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: For MinGW32 use 64-bit value formatting
	conventions which will work with any version of the WIN32 CRT.

2011-04-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jpeg.c (WriteJPEGImage): Properly handle errors reported
	by the JPEG library when writing.  Up to now, JPEG library simply
	invoked exit(), which crashed or hung if driven by Magick++ API.
	Fixes SourceForge bug 3106947 "Assertion failure when saving an
	"invalid" image as JPEG".

	* magick/module.c (ModuleAliases): Delete "XTRNBSTR"-entry. Fix by
	Stefan Graff.

	* contrib/win32/ATL7/ImageMagickObject/ImageMagickObject.cpp
	(Perform): Member "Perform" - out-commented SafeArrayAccessData
	and following SafeArrayUnaccessData. Fix by Stefan Graff.

	* contrib/win32/ATL/ImageMagickObject/MagickImage.cpp: Delete
	"XTRNSTREAM"-branch because "XTRNSTREAM" doesn't exist
	anymore. Fix by Stefan Graff.

	* coders/xtrn.c: In function "WriteXTRNImage" there is no branch
	for XTRNARRAY. Fix by Stefan Graff.

	* PerlMagick/Magick.xs: AdaptiveThreshold offset argument was
	being parsed into an 'unsigned long' rather than 'double' as it
	should have been.  This resulted in inability to handle negative
	offsets. Fixes SourceForge bug 3288735 "PerlMagick issue with
	AdaptiveThreshold".

	* coders/jpeg.c (ReadIPTCProfile): JPEG may deliver IPTC profile
	in chunks but code was only allowing one chunk, even though it was
	otherwise prepared to concatenate chunks.  Fixes SourceForge bug
	2978422 "Clipping paths in JPG images are truncated".

	* magick/utility.c (GetToken): Fix case where parser may run off
	end of string.  Also add asserts to check for passing null
	pointer.

2011-04-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/channel.c (ChannelImage): Report an error if the
	requested channel is not compatible with the image colorspace.
	Only deals with CMYK/RGB conflicts.  Resolves SourceForge issue
	3283046 "Bug in CMYK".

2011-03-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/txt.c (ReadTXTImage): Throw error if attempt to read
	empty file.

	* coders/{fits.c,mac.c,miff.c,pcd.c,pict.c,ps3.c,rla.c,txt.c}:
	Format requires seekable stream.

	* coders/pnm.c (WritePNMImage): Implement writer for PAM format.

	* coders/ept.c (WriteEPTImage): Fix error handling for case when
	TIFF writer fails.

	* magick/constitute.c (ReadImage): Use of GetBlobStatus() to
	evaluate image reader success is bogus.
	(MagickGetQuantumSamplesPerPixel): New private method to return
	the number of samples returned per pixel for a given quantum type.

2011-03-14  Glenn Randers-Pehrson  <glennrp@simple...>

	* coders/png.c (WriteOnePNGImage(): Fixed a rounding error in
	writing the pHYs chunk (it was truncating instead of rounding).

2011-02-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/magick.c (MagickPanicSignalHandler,MagickSignalHandler):
	Don't invoke DestroyMagick() since there may be OpenMP worker
	threads still running which are using data which would be
	deallocated.  Instead we invoke PurgeTemporaryFiles() to remove
	any existing temporary files. Valgrind will report leaks if the
	program is terminated by a signal but this causes no actual harm.
	Resolves SourceForge issue 3165456 "^C causes semaphore failure in
	MacOSX".
	(MagickPanicSignalHandler): Invoke abort() in panic signal handler
	so that we will reliably get a core dump.

	* magick/tempfile.c (PurgeTemporaryFiles): New private function to
	remove any existing temporary files but without destroying
	temporary file semaphore.

2011-02-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/pnm.c (ReadPNMImage): Fix mis-placed break in PAM header
	parser.

	* wand/magick_wand.c (MagickWriteImageBlob): Improve the
	documentation to mention the related use of MagickSetImageFormat()
	and MagickResetIterator().

2011-02-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/xwindow.c (MagickXBestFont): Check for a few more common
	font names, and ensure to always check for "fixed" as a final
	fallback.

2011-02-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* config/delegates.mgk.in: Added gs-cmyk entry.  Used if '-type
	ColorSeparation' is specified on the command-line prior to the PDF
	or Postscript file name.  This entry specifies use of the
	Ghostscript PAM driver which is capable of supporting CMYK output.
	This may be useful if it is desired to apply CMYK color profiles
	to the image returned from the PDF.  As fair warning, it seems
	that Ghostscript 8.62 outputs CMYK even if the PDF was in RGB
	space if the PAM driver is used.

	* coders/pnm.c (ReadPNMImage): Add support for reading netpbm's
	PAM format.

2011-02-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/rwblob.c, tests/rwfile.c: Fixes to help tests work when
	testing with multiple frames.

	* coders/sgi.c: SGI format is not documented to support multiple
	frames.  Remove the half-baked extension for it.

2011-02-01  Glenn Randers-Pehrson  <glennrp@simple...>

	* coders/bmp.c (ReadBMPImage): Changed file_size greater than
	expected from a corrupt-image error to a debug log entry.
	File_size too small is still an error, and made that so also for
	BI_RGB images which were previously exempted from the test.

2011-01-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/rwblob.c, tests/rwfile.c: Validate the data in each image
	frame, validate that each read returns the same number of frames,
	and validate that the correct number of frames was ultimately
	returned.

	* magick/blob.c (SyncBlob): Disable bogus code which attempted to
	replicate the blob I/O object across all images in the list when
	the blob is synced.  Leave a less bogus bit of code in place (but
	commented out) in case such functionality is deemed to actually be
	needed in the future.  The previous code was copying structs on
	top of each other, including a pointer member to a semaphore.

2011-01-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/Changes.rst: Add a new Changes page to wrap up the yearly
	change logs to lessen download size.

	* scripts/changelog2rst.sh: Simple utility to format ChangeLog
	format into something resembling reStructuredText.

	* www/Makefile.am: Use reStructuredText to format the ChangeLog
	files to HTML so that we can inherit the improved formatting and
	page style.

	* coders/pnm.c (ReadPNMImage): Support for multi-frame PNM was
	botched due to on-going edits to support PAM format.

2011-01-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c (MagickDescribeImage): Was sending
	descriptive output to stdout rather than returning it in an
