	* magick/blob.c (ReadBlob?SBFoo): Return 0 on EOF conditions
	rather than a magic value concocted using ~0.  The magic value was
	very sensitive to the size/range of the type used to pass and
	store it, leading to increased possibility of error.  There was

	the magic value.  Added documentation that EOFBlob() may be used
	to determine that the blob is in EOF state.

	* coders/pix.c (ReadPIXImage): Avoid reliance on a particular
	magic value being returned from ReadBlobMSBShort on EOF.

2007-09-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (CommandProgressMonitor): Remove any preceding

	* coders/{cmyk.c, gray.c, mono.c, rgb.c, uyvy.c, wbmp.c, yuv.c}
	(ReadFOOImage): Check for EOF while searching for start of image
	data.

	* tests/Makefile.am: Don't test PTIF format with blob I/O since it
	is not possible to pass the rwblob test and it is really an output
	driver rather than a format.

	* libtool: Update to latest CVS libtool.

	* magick/constitute.c (ExportModulo8Quantum): Move Import and
	Export macros from header file since they are not used anywhere
	else.

	* coders/dpx.c: Add underscore suffix to macro local variable
	names in order to avoid conflict with names in code using the
	macros.

2007-07-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c: Reduce the number of warnings when compiling
	the Wand library.

	* coders/xwd.c (XWD_OVERFLOW): Eliminate comparison between signed
	and unsigned.

	* coders/pnm.c (ValidateScalingIndex): Eliminate check to see if
	unsigned type is less than zero.

	* magick/log.c (LogMagickEvent): Even though log file name comes
	from a controlled source (log.mgk), perform safe numeric
	substitution on it.

	* coders/xwd.c (ReadXWDImage): Eliminate conflict between locally
	defined OVERFLOW macro and similarly named macro under Windows.

2007-07-18  Daniel Kobras  <kobras@debian.org>

	* coders/xwd.c (ReadXWDImage): Integer overflow fix
	(CVE-2007-1797).  From Debian patch
	xwd_integer_overflow_fixes_CVE-2007-1797.

	* coders/sun.c (ReadSUNImage): Sun segfault fix.  From Debian
	patch sun_segfault_fix.

	* magick/blob.c (ReadBlobStream): Never try to read data beyond
	EOF in blob streams. Some (but not all) ReadBlob*() methods
	already implemented similiar checks. Moving it to the central
	ReadBlobStream() increases robustness and prevents out-of-bounds
	reads.  From Debian readblob_offset_robustness patch.

	* coders/pnm.c (ReadPNMImage): Validate pixel scaling.  From
	Debian pnm_scale_fix patch.

	pcx_heap_overflow_fix patch.
	(ReadPCXImage): PCX segfault fix.  From Debian pcx_segfault_fix.

	* magick/montage.c, PerlMagick/t/montage.t: Do not pass bogus
	negative values to modulate shadow in montage. Instead, drop a
	constant grey shadow like current ImageMagick.  From Debian
	montage_shadow_fix patch.

	* coders/png.c (ReadMNGImage): MNG segfault fix.  From Debian
	mng_segfault_fix patch.

	* utilities/miff.4: MIFF man page apropos fix.  From
	Debian miff_apropos_fix patch.

	coder. (CVE-2007-1797).  From Debian dcm_overflow_fix patch.

	* coders/bmp.c (ReadBMPImage): Verify file seek success.  From
	Debian bmp_overflow_fix patch.

2007-07-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/utility.h (MagickReallocMemory): It seems that realloc()
	frees the provided memory pointer if the requested size is zero.
	This was causing MagickReallocMemory() to perform a double-free
	under error conditions.  Inspired by Debian
	realloc_double_free_fix patch by Daniel Kobras.

2007-07-18  Daniel Kobras  <kobras@debian.org>

	* magick/quantize.c (GrayscalePseudoClassImage): Fix computation

	* coders/miff.c (WriteRunlengthPacket): Converted excessively long
	macro to a function and hopefully eliminate warnings when using
	Visual Studio 2005.
	* magick/pixel_cache.c (ClonePixelCache): Eliminate bug when
	size_t is an unsigned type.

2007-07-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (SetImageInfo): Address security issue noted by
	CVE-2006-0082
	http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0082 in
	which output filenames matching arbitrary printf specifications
	may cause GraphicsMagick to crash.

	* magick/utility.c (TranslateTextEx): New version of TranslateText
	which allows copying each attribute via a user-provided callback
	function.

	* magick/delegate.c (InvokeDelegate): Implement secure delegate
	execution in POSIX environments in order to avoid injection of
	arbitrary shell commands via carefully crafted filenames.  Fixes
	Debian Bug 345238 "[CVE-2005-4601] Shell command injection in
	delegate code (via file names)"
	http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=345238

2007-07-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

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

	* magick/blob.c: Only replace getc_unlocked() and putc__unlocked()
	for a thread-safe build.

	* magick/studio.h: Always use fseeko() and ftello() if they are
	available.

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

	* coders/dpx.c (ReadDPXImage): Avoid using seek() if possible, and
	don't use at all if the input is not seekable.

	* coders/psd.c (ReadPSDImage): Eliminate memory leak when reading
	PSD files.  Fixes Sourceforge issue 1625477 "Memory leak reading
	layered PSD Image".

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

	* magick/command.c: Fixed -affine command argument
	validation. Fixes SourceForge issue 1743141 "Affine matrix option
	parsing".

	in order to obtain better read performance for 10-bit DPX.

	* magick/blob.c (OpenBlob): Added support for MAGICK_MMAP_READ and
	MAGICK_MMAP_WRITE environment variable options to enable input and
	output file access using mmap().

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

	* magick/blob.c (OpenBlob): Use MAGICK_IOBUF_SIZE to tune the size
	of the I/O buffer.  Sometimes performance is improved by using
	something other than the current default of 16KB.

2007-06-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/miff.c (ReadMIFFImage): Handle case where compression
	keyword is present but has value of `None`.

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

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

	* magick/resource.c (AcquireMagickResource): Map resource limit
	was not being properly checked due to a typo.  The memory limit
	was being tested instead.

	* coders/tiff.c (ReadTIFFImage): Use libtiff to decode OJPEG
	compressed files into RGB.  Probably requires new OJPEG
	implementation from Joris Van Damme which is new in libtiff and
	not yet released. I am not completely sure that this approach is
	correct yet.

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

	* magick/xwindow.c (MagickXGetWindowImage): Set image->depth
	appropriately.

	* many files: Compiler warnings reduction.

2007-05-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/cineon.c (ReadCINEONImage): Alter sample scaling
	algorithm a bit.	

	* tests/rwblob.c, tests/rwfile.c: Allow some slop when testing
	Cineon format with QuantumDepth=8 since we are currently only
	supporting 10 bit samples.

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

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

2007-05-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/cineon.c (WriteCINEONImage): Re-wrote Cineon writer from
	scratch.  There is no code originating from ImageMagick in this
	source module any more.

2007-04-30  Fojtik Jaroslav  <JaFojtik@seznam.cz>

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

2007-04-09  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/wpg.c (ReadWPGImage): Fix for SourceForge bug id 1431805
	"clip art wpg files cause access violation in graphics magick".

2007-04-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/pixel_cache.c (ModifyCache): Ensure that the cache nexus
	is open.  Fix for SourceForge bug id 1173713 "segfault in
	ModifyCache"

	* m4/acx_pthread.m4 (ACX_PTHREAD): Apply fixes necessary to
	support C++ compiler properly.

2007-04-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/GraphicsMagick.pc.in: Fix for SourceForge bug id 1576616
	"Fix includedir variable in pkg-config files".

	* magick/pixel_cache.c (GetOnePixel): Fix for SourceForge bug id
	1572357 "GetOnePixel definition appears incorrect".  It is true
	that this function is intended for read-only purposes and that the
	PixelPacket value is returned directly.

	* coders/pdf.c (WritePDFImage): Fix for SourceForge bug id 1510075
	"Failed to write PDF with JPEG compression".

	* magick/command.c (MogrifyImageCommand): Properly bubble up
	errors and terminate further mogrify processing immediately. This
	in response to SourceForge bug id 1391421 "problem doing resize on
	273x1 JPEG".

	* magick/magick.c (InitializeMagickClientPathAndName): Fix for
	SourceForge bug id 1315109 "segfault in InitializeMagick(NULL)".

	* wand/magick_wand.c (MagickGetQuantumDepth): Fix for SourceForge
	bug id 1353744 "MagickGetQuantumDepth doesn't work".

	format.

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

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

	* m4/acx_pthread.m4: Update version of ACX_PTHREAD macro used.

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

	* coders/wpg.c: Support CTM translation in WPG reader.

2007-03-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Store 10-bit Luma samples in the filled 32-bit
	storage word starting with the datum in the least significant
	position.

2007-02-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Updated autoconf to version 2.61.

2007-02-10  Daniel Kobras  <kobras@debian.org>
