path: root/ChangeLog.2012

2012-12-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c: Added -auto-orient to 'convert' and 'mogrify'
	to automatically rotate the image upright for viewing based on its
	current orientation setting.
	Added -orient to support setting the image orientation.

	* magick/shear.c (AutoOrientImage): New function to automatically
	orient the image so that it is upright for normal viewing.

2012-12-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* scripts/tap-functions.shi: Tidy TAP tests so that they may be
	run alone, or via Perl's 'prove'.

2012-12-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/rwfile.c (main): Test file name generation was not
	correct.

2012-12-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/rwfile.tap: Added -stdio tests for most file formats.
	This tests I/O using an already-opened file handle passed via the
	ImageInfo file member.  Formats using the Ghostscript delegate are
	not working right yet.

2012-12-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/rwfile.c (main): Added a '-stdio' option to test
	reading/writing files using file handles opened by the API user.

	* magick/blob.c (CloseBlob): It should be possible to invoke
	CloseBlob() multiple times, including blobs set to "exempt".
	There were some issues when passing in file descriptors.

2012-12-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/api/api.rst: Add another example Core C API example program.

	* magick/blob.c (OpenBlob): Restore file position, rather than
	rewind, after reading header bytes.

	* magick/image.c (SetImageInfo): Restore file position after
	reading header bytes.  Resolves SourceForge issue 3597486
	"ReadImage not working with file descriptors".

2012-12-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* VisualMagick: WIN64 (64-bit Windows) installer improvements to
	bring up to par with 32-bit installer.

2012-12-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* VisualMagick: WIN64 (64-bit Windows) is supported now.

2012-12-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/blob.c: Eliminate support for experimental
	MAGICK_MMAP_WRITE, which never quite worked correctly and did not
	provide performance benefits.

2012-12-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/blob.c (FileToBlob): Rewrite to be based on stdio.

2012-12-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/magick_types.h.in: Changes to try to work better with the
	Windows WIN64 API.

2012-12-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (SetImageColorRegion): The provided color should
	be in the same colorspace as the image.  The image is no longer
	converted to RGB with the expectation that the provided color is
	always some particular RGB.
	(AppendImages): No longer transform the canvas image to RGB.  Now
	append uses the first listed image to determine the colorspace
	which should be used when appending the additional images and of
	the output image.  The additional images are converted to the
	canvas image colorspace.  Likewise, the background color is
	assumed to be in the same colorspace as the first listed image so
	that it is compatible and can be used to fill the background color
	without translation.

2012-11-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* rungm.sh.in: Remove extraneous space in first line which
	prevents execution with T-shell (tsch).  Reported by William
	Langdon.

2012-11-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/wand/wand.rst: Add a simple example of using the Wand API.

2012-11-21  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

	* coders/bmp.c (ReadBMPImage): Fixed an old bug with decoding
	chromaticity primaries.

2012-11-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.h ("C"): Need to include wand/wand_symbols.h
	after magick/api.h in order for options from magick_config.h to
	take effect.

	* magick/symbols.h (PSPageGeometry): Fix typo. Should map to
	GmPSPageGeometry.

2012-11-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/wand_symbols.h, magick/symbol.h: MagickWand API is now
	prefixed with 'Gm' when the --enable-symbol-prefix configure
	option is supplied.  These changes are contributed by Ben Wu.
	Details of changes are as follows:

	1. A new header file wand/wand_symbols.h which prefixes all
	   MagickWand API symbols with Gm.
	2. Modification to all the header files in wand/ to include
	   wand_symbols.h.
	3. Modification to magick/symbols.h to include additional
	   symbols which were colliding with names in ImageMagick.
	4. Modification to magick/error.c to exclude function
	   definitions for MagickError, MagickFatalError,
	   MagickWarning, and ThrowException when building with
	   --enable-symbol-prefix option. There four names were also
	   defined as macros so it appears that putting them in a
	   symbol-remapping file wont work.

	* Makefile.am: Update Automake to 1.12.5.

2012-11-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Magick++/COPYING: Change Magick++ usage license to be exactly
	the MIT license without the additional sentence about retention of
	copyright (which was already legally implicit).

2012-11-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/symbols.h: Re-generate list of symbols to prefix.

	* magick/utility.c (IsGlob): IsGlob can be more efficient.

	* magick/floats.c: Use compile-time selection of endian-specific
	code rather than run-time.  Fix cast warning with 64-bit builds.

2012-11-07  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

	* coders/png.c (WriteOnePNGImage): The wrong QuantumType was
	sometimes passed to ExportImagePixelArea() by the PNG encoder.

	* coders/png.c (ReadOnePNGImage): Let libpng unpack all sub-8-bit
	pixels (see change of 2012-08-31 which lets libpng unpack sub-8-bit
	palette images; this also lets libpng unpack the grayscale images).

	* coders/png.c (ReadOnePNGImage): Corrected the reading of interlaced
	images (see SourceForge bug 3420695, in which all passes are
	displayed in a garbled manner instead of only the completed image).

2012-10-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c (MagickGetImagePage): Need to use 'image'
	rather than 'images' in order to work with iterator.
	(MagickSetImagePage): Need to use 'image'
	rather than 'images' in order to work with iterator.

2012-10-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/utility.c (TranslateTextEx): Fix bug with input string
	read overrun if the input string ends with a single '%'.  This
	sometimes caused random heap data to be added to the output string
	until another null character is reached.  A simple work-around
	without this fix is to use "%%" rather than "%".  Fixes
	SourceForge bug 3580219 "strange results with '%' in Annotate()".

2012-10-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c (MagickSetImagePage): New method to support
	setting the image page size and offsets.
	(MagickGetImagePage): New method to support getting image page
	size and offsets.

2012-10-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Report fatal error if doing modules build and
	libltdl is not found.

2012-10-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* ltdl: Libltdl is no longer bundled.  Libltdl must be previously
	installed on the system in order to build the modules
	configuration.

2012-10-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/index.rst: Update top index page for 1.3.17 release.

	* NEWS.txt: Update NEWS for 1.3.17 release.

	* version.sh: Update shared library versioning for 1.3.17 release.

	* coders/jnx.c: Fix format string compilation warnings.  Remove
	MS-DOS line terminations.

	* configure.ac: Module loading is now only supported by the
	modules build and not just because shared libraries are enabled.
	This means that libltdl is only depended upon by the modules
	build.  Sometime in the future, libltdl will no longer be bundled
	in the GraphicsMagick source tree.

2012-10-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac (LTDL_INIT): Request installable libltdl rather
	than convenience.

2012-10-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/bmp.c: Support alpha channel in uncompressed 32-bit BMP.
	Resolves SourceForge issue 3566239 "Can't open BMP with alpha
	created by photoshop".

2012-10-07  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* dcraw/dcraw.c: Fixed situation when M_PI is not defined.

2012-10-07  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/jnx.c: Add image attribute with geolocation.

2012-10-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* dcraw: VisualMagick configure fixes to support linking with JPEG
	and JPEG2000.

2012-09-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* dcraw: Add dcraw to VisualMagick build.

	* libxml: Update libxml2 to 2.9.0 release.

2012-09-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am: Update to Automake 1.12.4.

2012-09-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* doc/options.imdoc: Fix Debian bug 687738 "graphicsmagick:
	repeated words suitable for suitable for in gm manpage" reported
	by Jonas Smedegaard.

2012-09-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* NEWS.txt: Update with news since last release.

	* configure.ac: Added the configure option
	--enable-quantum-library-names to enable that shared library name
	includes quantum depth to allow shared libraries with different
	quantum depths to co-exist in same directory (only one can be used
	for development).

2012-09-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/effect.c (AdaptiveThresholdImage): New implementation
	contributed by Roberto de Deus Barbosa Murta.  Executes in linear
	time as threhold area is increased rather than being quadratic.

2012-09-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/svg.c: Fix improper injection of XML headers as rendered
	text.

	* magick/render.c (DrawImage): Fix SourceForge issue 3499164
	"Drawing of text fails if text starts with "," character".  Fix
	SourceForge issue 3411492 "Certain SVGs hang GraphicsMagick".  Fix
	SourceForge issue 1961000 "Could not print ',' via convert draw
	text".

2012-09-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/wmf.c (lite_font_stringwidth): Simply return zero.
	Returning a computed string width was causing text placement
	problems when testing with libwmf's fulltest.wmf.

2012-08-31  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

	* coders/png.c: ReadOnePNGImage: sub-8-bit palette images were
	getting unpacked twice; once by libpng via png_set_packing()
	and again by coders/png.c in a switch() statement around line 2500,
	resulting in horizontally stretched pixels.

2012-08-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am (AUTOMAKE_OPTIONS): Include lzip as a distribution
	format again.

2012-08-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: BrowseDelegate now defaults to 'xdg-open', but if
	it is not found, then configure will search for firefox,
	google-chrome, mozilla (in that order).

2012-08-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: For testing on MinGW, assume that Postscript is
	available since we don't have a good way to check for that.

	* scripts/tap-functions.shi (test_count): Always execute the test
	program rather than skipping execution since we want to make sure
	the test program fails correctly as well.

	* coders/gif.c (DecodeImage): Add a log message for attempted LZW
	string data table overflow.

2012-08-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/effect.c (ConvolveImage): Allocate normalized convolution
	kernel using cache-line aligned memory allocator.

	* configure.ac: Remove support for legacy LZWDecodeDelegate and
	LZWEncodeDelegate since these are not used any more.

2012-08-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* scripts/tap-functions.shi: If a test declares that it needs
	certain features, skip the test if required features are not
	available.

	* configure.ac: Build a supported features list and save to
	common.shi script for use by test scripts.

	* Makefile.am (LOG_COMPILER): Run Bourne-shell based TAP scripts
	with the same shell $(SHELL) that configure selected for the
	Makefile to use.

2012-08-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am (AUTOMAKE_OPTIONS): Update to Automake 1.12.3.
	Update test suite to use Automake TAP driver rather than legacy
	tests.

2012-08-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jnx.c (ExtractTileJPG): Add a trace of tile offset and size.

2012-08-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jnx.c (ExtractTileJPG): Use a memory buffer for the JPEG
	tile rather than a temporary file.

2012-08-12  Fojtik Jaroslav  <JaFojtik@seznam.cz>

        * PerlMagick/t/input_jnx.jnx: Small JNX test file.

2012-08-11  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/jnx.c: speedup.

2012-08-10  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	overflow.

2012-08-05  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/jnx.c: Fixed.

2012-08-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jnx.c: Add JNX coder for "Garmin proprietary Image
	Format" (implementation by Jaroslav Fojtik) to the build.  Code is
	not yet working properly at this time.

2012-08-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Remove use of -Wl,-zlazyload under Solaris since
	it seems to decrease the stability of C++ exceptions in x86-64
	build and does not measurably improve runtimes.  Don't force use
	of liblzma because libtiff is used.  User should always have
	control.

2012-07-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/memory.c (MagickMallocAligned): Use RoundUpToAlignment()
	macro to compute aligned pointer.

	* magick/effect.c (EnhanceImage): Eliminate use of ugly Enhance
	macro.  Only filter based on color channels (ignore opacity).

2012-07-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/studio.h (MAGICK_CACHE_LINE_SIZE): Assume a cache line
	size of 64 bytes except for on PowerPC which uses 128.

	* magick/pixel_cache.c: Use aligned memory allocator to allocate
	structures and buffers which might suffer from false cache line

2012-07-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/effect.c, magick/random.c, magick/semaphore.c: Use
	aligned memory allocator to align allocations which should be
	aligned to cache line boundary.

2012-07-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/memory.h (MagickAllocateAlignedMemory): New macro to
	allocate aligned memory.
	(MagickFreeAlignedMemory): New macro to free aligned memory.

	* magick/memory.c (MagickMallocAligned): New internal function to
	allocate aligned memory.
	(MagickFreeAligned): New internal function to free aligned memory.

2012-07-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/common.h (MAGICK_ASSUME_ALIGNED): Add some GCC attribute
	wrappers for useful features added by GCC 4.7.

2012-07-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/gif.c (ReadGIFImage): Try to be better about reporting
	failure when ReadBlob() fails to return the requested number of
	bytes.

2012-06-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/benchmarks.rst: Strip the outdated benchmark results from
	the benchmarks page.

	* magick/command.c (ImportImageCommand): Status returned from the
	command was inverted.

2012-06-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Release GraphicsMagick 1.3.16

2012-06-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (MogrifyImage): -units was adjusting existing
	resolution the wrong way around.

2012-06-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* jpeg: Updated to IJG 8d release.

	* libxml: Updated libxml to 2.8.0 release.

	* zlib: Updated zlib to 1.2.7 release.

	* magick/blob.c (MagickFileHandle): Refer to stdio, bzip2, and
	gzip file handles using their own type.  Eliminates warnings
	observed when compiling with zlib 1.2.7.

	* tiff: Updated libtiff to 4.0.2 release.

	* png: Updated libpng to 1.5.11 release.

2012-06-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Fix typo which caused the --without-lzma option to
	be handled incorrectly.  Resolves SourceForge issue 3535309
	"graphicsmagick from 1.3.13 to 1.3.15 has broken lzma support".

2012-06-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/rwfile.c (main): Verify that we can 'ping' the file using
	PingImage().  Tests for some formats may take longer to complete.

	* tests/rwblob.c (main): Verify that we can 'ping' the blob using
	PingBlob().  Tests for some formats may take longer to complete.

	* coders/xbm.c (ReadXBMImage): Fix memory leak of temporary X
	bitmap image allocation encountered when reading in 'ping' mode.

	* magick/blob.c (PingBlob): Re-write to be based on BlobToImage()
	so that it works reliably.
	(BlobToImage): Restore original input file name to image if
	temporary file was used so that image 'filename' and
	'magick_filename' do not contain unexpected content due to using a
	temporary file.

2012-06-07  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

	* coders/png.c: Disable new libpng-1.5.10 test for invalid palette
	index when reading a PNG or MNG (for speed), or when writing a MNG
	(because a zero-length PLTE is valid in a MNG).

2012-06-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/attribute.c (SetImageAttribute): Don't translate
	'comment' and 'label' attributes if the request is made while a
	file is being read.  This is a temporary workaround until there is
	opportunity to modify the architecture so that there is a clear
	split between user-provided settings and values obtained from the
	input image.

	* magick/blob.c (GetBlobIsOpen): New function to return if blob is
	currently open.

2012-06-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* PerlMagick/typemap: Add typemap file needed by Perl 5.16.
	Resolves SourceForge issue 3531512 "PerlMagick does not build with
	perl 5.16".

2012-05-29  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

	* coders/png.c: Ignore APNG chunks even if we are using a libpng
	that was built with the "APNG patch".

2012-05-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (ConvertImageCommand): +repage does not require
	an argument.  Resolves SourceForge issue 3529158 "+repage option
	not respected with convert command".

	* configure: Update to Autoconf 2.69.

	* magick/effect.c (MotionBlurImage): Motion blur does scale so
	remove DisableSlowOpenMP for it.

	* magick/command.c (BenchmarkImageCommand): Remove parenthesis
	from output, and change "iter/sec cpu" to "iter/cpu" to ease
	parsing.

	* magick/pixel_cache.c (GetPixelCacheInCore): Consider read-only
	memory-mapped cache as being "in-core".  Otherwise MPC input files
	are penalized.

2012-05-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/api.h: Include <sys/types.h> on POSIX systems in order to
	help assure that 'size_t' and 'ssize_t' are declared.

2012-05-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/magick_config_api.h.in: Need to provide definitions for
	'size_t' and 'ssize_t' in case the system headers lack these types
	because the definition of MagickExtentImage() requires them.  This
	should resolve PHP bug #62034 "gmagick does not compile".

2012-05-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/pixel_iterator.c (GetRegionThreads): Don't thread region
	if it is not memory-based.

2012-05-09  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

	* coders/png.c (ReadOnePNGImage): make transparent_color elements
	unsigned long instead of unsigned short, so 65537 is actually out of
	range as expected, and won't match any pixel if no tRNS chunk is
	present.

2012-05-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/sfw.c (ReadSFWImage): Reader needs to be more robust
	against corrupt or maligned headers.  Resolves SourceForge issue
	"sfw file crash".

2012-05-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/pdf.c (WritePDFImage): Add file basename as the PDF
	document title.  Resolves SourceForge bug ID 2835140
	"GraphicsMagick fails to add title attribute to PDF output".

	* coders/sfw.c (ReadSFWImage): Restore original filename and
	format.

	* PerlMagick/t/jpeg/read.t: Add a test for reading Seattle
	FilmWorks format based on the sample image from
	http://www.algonet.se/~cyren/sfw/.  Image was approved for
	distribution in GraphicsMagick by Bengt Cyrén.

	* magick/analyze.c (GetImageBoundingBox): Only apply opacity-based
	bounding box detection if all three test points are non-opaque and
	the same value.  Resolves SourceForge bug ID 3522804 "convert
	-trim fails on 8-bit PNG that ImageMagick can trim".

	* coders/sfw.c (ReadSFWImage): Fix variety of bugs related to
	closing Image and blob at wrong points.  SFW reader is working
	again.  Resolves SourceForge bug ID 523430 "sfw file open failed".

2012-05-01 Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/mat.c Animated movies inside 4D matrices are loaded now.

2012-04-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/pixel_iterator.c: Limit the number of threads to use in
	the loop rather than the total number of threads available.

2012-04-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Release GraphicsMagick 1.3.15

2012-04-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (SetImageInfo): Remove automatic adjoin mode
	support logic.
	(AddDefinition): Fix use of uninitialized variable.

2012-04-23  Glenn Randers-Pehrson  <glennrp@simplesystems.org> 

	* doc/*.imdoc: some example commandlines in the documentation
	were missing the leading "gm ".

2012-04-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/blob.c (FormMultiPartFilename): No longer add a
	printf-style scene formatting specification to filenames which do
	not have one and no longer automatically operate in 'adjoin' mode
	in such cases.  This is a BIG CHANGE for users who may have become
	used to this automatic functionality.  The simple solution to
	update existing scripts depending on this behavior is to change
	any bare filenames to include a format specification similar to
	"image-%d.jpg" and add +adjoin to the command line.  The reason
	why this change is made is that the output files produced by any
	given operation were unpredictable, and it was causing temporary
	files to be leaked due to the renaming.

2012-04-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/bmp.c (WriteBMPImage): Enforce that image width and
	height do not exceed BMP dimensions.  BMP dimensions are
	represented by a signed type.  BMPv2 supports maximum dimensions
	of 32k by 32k.

2012-04-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/info.c (WriteINFOImage): When driven by the 'convert'
	utility, -format produces user-controlled formatted output similar
	to -format in 'identify'.  This is accomplished via a
	'info:format=value' define.

	* magick/image.c (AddDefinition): New function for adding just one
	define to definitions list.

2012-04-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/pnm.c (ReadPNMImage): Completely disable OpenMP in reader
	because there is too much contention.

	* magick/pixel_iterator.c: Dereference image to be modified in
	non-threaded context in order to lessen contention.

	* magick/semaphore.c (AllocateSemaphoreInfo): Make sure that
	SemaphoreInfo does not share cache lines with another semaphore.

2012-04-11  Glenn Randers-Pehrson  <glennrp@simplesystems.org>

	* coders/png.c: fixed problem with bit depth when the encoder
	decides to write RGBA instead of indexed PNG, by delaying the
	call to png_set_tRNS() until after calling png_set_IHDR().

2012-03-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* png: Update bundled libpng to 1.5.10 release.  Provides security
	fix for CVE-2011-3048.

	strncpy().
	(CopyMagickString): Depend on strlcpy() because we provide it if
	it is missing.
	(ConcatenateMagickString): Depend on strlcat().

	* coders/xcf.c (ReadXCFImage): Now respects image subimage and
	subrange members so that returned image layers may be selected.
	Based on patch from SourceForge issue 3513025 "XCF reads all
	layers all the time".

	* magick/resize.c (ThumbnailImage): Thumbnail default filter is
	intended to be the box filter, but allow the user to override the
	filter used.  Resolves SourceForge issue 3513239 "-filter command
	line argument ignored".

2012-03-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (ConvertImageCommand, MogrifyImageCommand):

	systems with limited command line length.  This means that lzip
	support is temporarily removed.

	* magick/resize.c (ResizeImage): Resize filter argument was being
	ignored.  Filter from image 'filter' member was used instead.
	Problem was reported by Steven Bakhtiari.

	'alloc_size', 'hot', 'cold'.

	* magick/{log.h,monitor.h,utility.h}: Use double-underscore syntax
	in GCC format attribute specifications to defend against
	accidental macro expansion.

2012-02-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/xcf.c (ReadXCFImage): Fix reading XCF which is comprised
	of different sized layers.

	"*.MEF file open incorrect".

2012-01-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jpeg.c (WriteJPEGImage): Convert RGB-compatible
	colorspaces (e.g. CineonLog) to RGB by default since that was the
	case prior to release 1.3.13.  User can still override it
	(avoiding removal of log encoding) by explicitly specifying the
	desired colorspace.  Problem was reported by Gary Margiotta.

2012-01-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (ReadDPXImage): When reading, save input file
	endianness so that the endianness of the original file is
	preserved by default.  The user is able to override this default
	via -endian.  Problem was reported by JongAm Park.

	Resolves SourceForge bug #3475148 "memery leaks".

	* magick/module.c (ModuleAliases): EMF format is supported by EMF
	module and so mapping EMF to the WMF module caused EMF not to
	work.  Resolves SourceForge bug #3475147 "emf files can not be
	opened".  Note that the EMF module only works for Microsoft
	Windows.

2012-01-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/gem.c (Hull): Improve performance.

	* magick/effect.c (DespeckleImage): Improve performance.

2012-01-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/effect.c (DespeckleImage): Using schedule(static,4)
	blocks any opportunity for speedup.  This was a performance
	regression.  Oops!

2012-01-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c (MagickExtentImage): Added
	MagickExtentImage() to Wand API.  Resolves SourceForge issue
	#3471915 "MagickExtentImage in the Wand C API".
