	count value.

2015-02-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Magick++/lib/{Blob.cpp, Image.cpp}: Incorrect lock scope
	resulted in Magick++ locking not actually working to protect
	critical sections in spite of no detected problems with locking
	these past 16 years.  Problem was detected using the
	misc-unused-raii check from clang-tidy and was reported by Hyrum
	Wright.

	* coders/palm.c (ReadPALMImage): Add header logging to writer.
	Writer still seeks and overwrites its own header so logging is not

	* Magick++/lib/Image.cpp (Image::quiet()): Patch by Dirk Lemstra
	to support silencing warnings in Magick++.  Adds a quiet() method
	which blocks (ignores) warning exceptions when passed a true
	argument.  Warning exceptions are still generated by default.

	enable that warnings reported by libtiff are thrown as warning
	exceptions so that they may be caught or will be reported at the
	gm command-line.

	not return a value if it does not return.

	* magick/error.c (DefaultFatalErrorHandler): Invoke
	PanicDestroyMagick() rather than DestroyMagick().  If we are

	functions in signal handler.
	(PanicDestroyMagick): New function for emergency release of
	persistent resources just prior to program exit.  Async-safe and

	file header is a supported depth before using it further in the
	code.  This might resolve Coverity CID 10071 "Bad shift
	operation".
	(ReadDPXImage): Check for EOF while reading forward to element
	data.  Might solve Coverity CID 10305.

	"Missing unlock".

	* magick/colormap.c (ReplaceImageColormap): Allocate new image
	colormap up front in order to avoid the possibility that we are
	left with an image with no colormap due to memory allocation
	failure. If there is a memory allocation failure, then the
	original colormap is preserved.  Resolves Coverity CID 10194
	"Dereference after null check".

	(change_delay should be change_timeout) reported by Coverity
	CID 10090.

2015-01-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (CloneImage): The definition is poor as to what a
	non-orphan clone should do.  However, the definition surely does
	not include crashing the software or supplanting the original
	image in an image list.  Clone image blob and previous/next
	pointers but do not supplant original image in list.  Resolves
	Coverity CID 10155.

2015-01-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/tempfile.c (AcquireTemporaryFileDescriptor): Avoid buffer
	overrun in the case of an astonishingly long environment variable
	string.  Resolves Coverity CID 10267.

	stack allocation to update argv[0]. Removed updating argv[0] until
	a better design can be found.  Resolves Coverity CID 10223.
	(GMCommandSingle): Plan B: Use static allocation from

2015-01-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/resource.c (InitializeMagickResources): Base image width
	and height default limits on the range of a 32-bit signed integer,
	even for 64-bit builds.  These limits are still beyond what most
	computers in the world can handle.  Limits can be increased by the
	user.

	* coders/sun.c (ReadSUNImage): There is no definition for Sun map
	type RMT_RAW so it can not be supported.  Update DirectClass
	pixels directly rather using SyncImage().  Problem was reported by
	Jodie Cunningham.

2015-01-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/pict.c (ReadPICTImage): Fix PICT reader crash when
	reading corrupted file.

	* coders/sun.c (ReadSUNImage): Sun reader was still not as robust
	as it should be.  Now it is.

2014-01-10 Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/wpg.c Fixed reading behind EOF issue.

2015-01-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (LSBPackedU32WordToOctets): Fix typo which adds
	severe corruption to encoded little-endian 32-bit packed output.
	The good news is that since the corruption is severe, it is easily
	visually detected.  The problem has corrupted all such
	(little-endian 10-bit) output since it was originally implemented
	on 2007-06-17 (changeset 11686, first released in GraphicsMagick
	1.1.8).  GraphicsMagick preserves the endianness of input DPX
	files by default, defaults to big-endian, and DPX files are
	commonly big-endian, so this problem may not have occured for many
	usages.  Problem was reported by Steve Dabner on the
	GraphicsMagick discussion mailing list.

2015-01-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/magick.c (MagickPanicSignalHandler): Print a message in
	the case of signals SIGXCPU and SIGXFSZ.

	* coders/bmp.c (ReadBMPImage): Don't hang in endless loop if EOF
	is encountered while checking for "BA" header.

	* coders/icon.c (ReadIconImage): Limit icon image allocation size.

2015-01-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/icon.c (ReadIconImage): Removed all of the
	previously-existing DIB reading code from icon.c and use new
	"ICODIB" reader to read DIB icons, or the PNG reader to read PNG
	icons.

	* coders/dib.c (ReadDIBImage): Added an "ICODIB" coder for
	internal use which reads a Windows BMP 3 DIB followed by a Windows
	ICO alpha mask.  This allows existing DIB code to be used to read
	ICO directory entries.

2015-01-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/icon.c: The Windows ICO reader is now more robust.  Still
	a work in progress since some files still can not be read or read
	incorrectly.

2015-01-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/resource.c (ListMagickResourceInfo): "kilo" for binary
	prefixes is supposed to be "Ki".

	* magick/utility.c (FormatSize): "kilo" for binary prefixes is
	supposed to be "Ki".

2015-01-01  Glenn Randers-Pehrson  <glennrp@simple.dallas.tx.us>

	* coders/png.c: Use WidthResource and HeightResource instead
	of fixed 1-million limit for rows and columns.

2015-01-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/utility.c (FormatSize): Add 'i' to value range
	identifiers since these are all in units of 2^10 rather than 1000.

	* magick/pixel_cache.c (CheckImagePixelLimits): Fix typo and
	produce an informative error message.

	* magick/resource.c: Added support for Image width and height
	pixels resource limits.

	* magick/resource.h (ResourceType): New resource enumerations
	WidthResource and HeightResource.

	* magick/enum_strings.c (StringToResourceType): Added support for
	parsing '-limit Width' and '-limit Height'.

	* magick/pixel_cache.c (CheckImagePixelLimits): New function to
	test image to see if it exceeds pixels limits.

	* coders/viff.c (ReadVIFFImage): Make the VIFF reader robust with
	detecting and reporting problems.
