	* tiff: Update to libtiff 3.8.0. 

2005-12-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* NEWS: Updated with latest changes.

	* tiff: Update to libtiff 3.7.4.

2005-12-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* lcms: Update to lcms 1.15.

2005-12-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/enhance.c (LevelImage): Fix -level command parsing when a

	end.

	* magick/utility.c (GetGeometry): Bounds-check geometry string
	length.

2005-12-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Decided to swap 10-bit subsampled 4:2:2 YCbCr by
	default since this is what practically all sample files I have
	been provided actually do.  Ignore the fact that there is nothing
	in the standard which supports this.

2005-12-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (NormalizeSamplingFactor): Generalized
	subsampling notation parsing support.

2005-12-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (NormalizeSamplingFactor): Add some support for
	normalizing industry-standard subsampling notation (e.g. 4:2:2)
	into GraphicsMagick's unusual notation.

2005-12-06  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

	* Updates to use latest development autotools, including
	development libtool 2.0.

2005-12-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.h: Added some useful macros for accessing
	PixelPacket members in a generic way.

	* coders/dpx.c (ReadDPXImage): For YCbCr with `A` sample, `A`
	sample levels are like Luma.
	(WriteDPXImage): For YCbCr with `A` sample, `A` sample levels are
	like Luma.

2005-12-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (RegisterTIFFImage): Report libtiff release
	version rather than ABI version.

2005-11-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/resize.c: Revert yesterday's benign-appearing edits since
	they caused a bizzare bug.

2005-11-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (ReadDPXImage): Improve performance when reading
	YCbCr files.  Handle files which use Printing Density on top of
	YCbCr.  Default YCbCr to Rec.709 if the transfer characteristic is
	User Defined.

	* coders/pcd.c (Upsample): Moved Upsample from gem.c to here since
	PCD is the only user and it is not a general purpose function.

2005-11-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* VisualMagick/magick/magick_config.h.in: Remove unnecessary test
	for WIN32.

2005-11-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_compat.c (FormatMagickStringList): MagickExport since this
	function is used by Ch extension.

	* magick/log.c (LogMagickEventList): MagickExport since this
	function is used by Ch extension.

	* magick/utility.c (FormatStringList): MagickExport since this
	function is used by Ch extension.

	* coders/dpx.c (ReadDPXImage): Added support for dpx:swap-samples
	define in order to handle files with Cb and Cr swapped.  Fixed a
	bug in the header reading which caused some valid files to fail to
	read at all.
	(WriteDPXImage): Added support for dpx:swap-samples define in
	order to write files with Cb and Cr swapped.

	* magick/profile.c (ProfileImage): Add support for ICC CMS
	profiles in YCbCr space.

2005-10-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/svg.c (ReadSVGImage): Eliminate memory leak.

2005-10-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.h (Image): Added an orientation member to the Image
	structure to record image orientation for the DPX, and TIFF
	formats. Eventually formats which support IPTC and EXIF embedded
	profiles should be supported by the orientation member as well.

2005-10-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* VisualMagick/magick/magick_types.h.in: Add patch for Ch.

	* magick/command.c (TransmogrifyImage): Complete re-write of
	mogrify file handling.  Former version wrote to a temporary file
	and then moved temporary file to replace original if necessary.
	New version moves an existing writable file to a backup file with
	tilde (`~`) added to end of file name, writes to the final output
	file name, and removes the backup file on success.  The new
	approach satisfies formats which embed the output name in the file
	(e.g. the DPX format) and still works when the output file exists
	and is writeable, but is in non-writeable directory.  The previous
	approach would fail if the output file exists and is writable, but
	the directory is not writeable.

2005-10-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (AttributeToString): Use strncpy rather than
	strlcpy to copy string.  This is important since DPX header
	strings are not null terminated and may need to fill all available
	space.  Certain short header fields like mp.film.manufacturer.id,
	mp.film.type, and mp.perfs.offset were being truncated!

2005-09-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/attribute.c (GetImageAttribute): Add more general support
	for retrieving wildcarded attributes so that an identify -format
	specification like `%[dpx:*]` works as expected.

	* coders/tiff.c (WriteTIFFImage): Transform quality value into zip
	compression quality level similar to what is done for MIFF/MNG/PNG.
	Since default quality value is 75, this means that the default zip
	quality level is 7.

2005-09-24  Peter Wu  <peterw@softintegration.com>

	* Incorporate changes necessary so that GraphicsMagick can work
	with the Ch C/C++ interpreter from SoftIntegration at
	http://www.softintegration.com/.

2005-09-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/pixel_cache.c: Incorporate all functionality from
	cache.c, cache_view.c, and stream.c so that all private interfaces
	can be fully hidden.  As a result cache.c, cache_view.c, and
	stream.c are now removed.

2005-09-18  Michal Kowalczuk  <sammael@brzydal.eu.org>

	* coders/gif.c: Free global_colormap before returning with error.

2005-09-18  Stepan Kasal  <kasal@ucw.cz>

	* Makefile.am (BUILT_SOURCES): Removed.

	* magick/Makefile.am (MAGICK_BUILT_SRCS): Removed, too.

2005-09-12 Glenn Randers-Pehrson <glennrp@glennrp.com>

	* magick/profile.c (ProfileImage):  Free color_profile->name
	and iptc_profile->name when destroying the profile.

2005-08-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/api.h: Eliminate requirement to include certain system
	headers prior to including <magick/api.h>.

	* utilities/gm.c: Move utility implementation to GMCommand() in
	command.c

2005-08-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Added support for reading and writing DPX Luma
	files using proper video levels.

	* magick/colorspace.h (enum ColorspaceType): Decided that
	GRAYColorspace should be reserved for full-range grayscale data
	while Rec601LumaColorspace and Rec709LumaColorspace should be for
	video colorspaces.  Therefore, GRAYColorspace is no longer a
	synonym for Rec601LumaColorspace.

	* magick/colorspace.c: Added support for influencing Cineon Log
	colorspace transformations via image attributes.	
	Perform colorspace transformations in floating point rather than
	integer in order to reduce the amount of noise added by
	transform table quantization.

	* coders/psd.c (WritePSDImage): Ensure that output image is 8 or
	16-bits regardless of specific image depth.

	* coders/dpx.c: Added support for planar YCbCr 4:2:2.

2005-08-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (WriteDPXImage): 10 and 12-bit packed data was not
	according to DPX specification.  Added dpx:pixel-endian={lsb|msb}
	to allow the user to specify the endian order of the pixel data in
	case it does (or should not) not match the headers.  Library Of
	Congress format is 10-bit packed data in big-endian format, but is
	marked as little-endian.

2005-08-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Sample order for filled 10 bit samples matches DPX
	specification (was intentionally reversed).  RGB sample order is
	changed to match DPX specifiation (i.e. BGR rather than RGB).
	Disabled special support for Library Of Congress little-endian
	10-bit packed format.

2005-08-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Extend all image rows to a 32-bit integer
	boundary.

2005-07-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Support the little-endian 10-bit packed format as
	used by the Library Of Congress.

2005-07-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jp2.c: Change how Jasper is intialized.  Hopefully
	eliminate memory leak when reading ICC color profile.

	* Overall: Compilation warning elimination with GCC 4.0.1.

	* magick/utility.c (SystemCommand): Always report error status if
	a command fails.

2005-07-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* zlib: Updated to version 1.2.3.

	* coders/dpx.c: Use TriangleFilter for scaling chroma.

2005-07-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Support proper encode and decode of YCbCr video
	levels.

	* magick/colorspace.c: Support Rec709YCbCrColorspace colorspace.

2005-07-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/{animate.c, display.c, import.c, xwindow.c}: Rename all
	symbols starting with `X` so that they are prefixed with `Magick`.
	This eases maintenance since it is almost impossible to understand
	code which pretends to be the X11 libraries.  The few programs
	which use the GraphicsMagick `X` functions will need to alter the
	symbol names they use.  Sorry.

	* magick/command.c (DisplayImageCommand): Don't invoke
	XrmDestroyDatabase() to destroy the resource database associated
	with the display since it seems that XCloseDisplay() does this for
	us.

	* magick/image.c (DisplayImages): Don't invoke
	XrmDestroyDatabase() to destroy the resource database associated
	with the display since it seems that XCloseDisplay() does this for
	us.

	* coders/uyvy.c: Enforce image width restrictions.

	* coders/dpx.c: Enforce image width restrictions when subsampling.

2005-07-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Support reading and writing subsampled CbYCr
	images.  Colorimetery is not right yet.

	* magick/colorspace.h (enum Rec709YCbCrColorspace): New
	enumeration for Rec. 709 YcBCr colorspace.

2005-06-21 Glenn Randers-Pehrson <glennrp@glennrp.com>

	* coders/png.c: Fixed a problem with reading 16-bit PNG images
	using the Q8 quantum depth.

2005-06-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (ReadDPXImage): Add read support for CbYCr at 4:4:4.
	(WriteDPXImage): Add write support for CbYCr at 4:4:4.

2005-06-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (WriteDPXImage): Only preserve source image
	dimension and offset information if image size has not changed.
	If image size has changed, the existing information may become
	invalid.
	(WriteDPXImage): Allow user to assign DPX header attribute values
	using syntax like "-define dpx:mp.frame.position=1000".

2005-06-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/fpx.c: Fix compilation problem due to additional
	ExportImagePixelArea parameter.

2005-06-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/png.c (WriteMNGImage): Use -define mng:need-cacheoff to
	write a libmng-specific nEED request to disable frame buffering.
	This allows the MNG data to stream without increasing memory
	consumption in the libmng client.

2005-06-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (SMPTEStringToBits): Time code and user bits were
	being displayed in wrong order on little endian CPUs.  Thanks very
	much for bug report from Jason Howard.
	(SMPTEStringToBits): Similar fix for time code and user bits
	string to binary.

2005-06-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/miff.c (ReadMIFFImage): Use StringToColorspaceType() to
	parse colorspaces.
	* coders/dpx.c (ReadDPXImage): Change existing
	dpx:source-colorspace define to dpx:colorspace so it is easier to
	remember.

	* coders/cineon.c (ReadCINEONImage): Extract Cineon header
	attributes in DPX compatible form so that it is possible to
	convert Cineon to DPX while losing as little header information as
	possible.  Allow the user to set the existing image colorspace
	using the cineon:colorspace define.

2005-06-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jpeg.c (ReadJPEGImage): Report actual depth of JPEG file
	(8 or 12 bits).

	* coders/cineon.c (ReadCINEONImage): Report depth as 10 bits.

2005-05-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Retrieve and restore the DPX user defined data
	area.  Make available as a "DPXUSERDATA" attached profile.

2005-05-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/meta.c (ReadMETAImage): Fixed reading ICM color profile
	files.  Due to a typo ICM color profiles were being stored as IPTC
	profiles.  This restores proper operation of the -profile option.
	(ReadMETAImage): Fix double free bug.  Hopefully does not result
	in a memory leak in other cases.

2005-05-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/image.c (DescribeImage): If the image is DirectClass,
	then don't compute the number of unique colors unless verbose is
	greater than one.  This change is made since computing the number
	of unique colors may take hours for some images.  The handling of
	the -verbose argument is changed so that it is cumulative.
	Specifying -verbose multiple times increases the level of
	verbosity.

2005-05-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/nt_base.c (NTreaddir): Fix write beyond buffer length
	reported in SourceForge issue #1182003.  Only impacts Windows.

2005-05-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (ReadRowSamples): Added necessary masking necessary
	in order to cleanly retrieve DPX 10 bit samples.  Happened to work
	properly without the masking with QuantumDepth=16.

2005-05-16  Tavis Ormandy <taviso@gentoo.org>

	* coders/xwd.c (ReadXWDImage): Fix for infinite loop in the xwd
	decoder when calculating the shift r/g/b values and the mask is
	set to zero.

2005-05-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/jp2.c (ReadJP2Image): Return JP2 images as DirectClass
	grayscale rather than PseudoClass.

	* coders/gray.c (ReadGRAYImage): Return GRAY images as DirectClass
	grayscale rather than PseudoClass.

	* coders/dpx.c: Rewrote the DPX pixel reading/writing code yet
	again to obtain up to 2X better performance.  In the process,
	support little-endian pixel storage.

2005-05-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c: Added some performance optimizations for reading
	and writing.  Write the motion picture and television headers.

	* magick/colorspace.c (TransformRGBImage): Update image colorspace
	to RGB when transforming from Cineon log space to RGB.

	* coders/dpx.c (WriteDPXImage): Set image date & time field.
	(ReadDPXImage): Retrieve television header SMTPE time code and
	user bits and return them as a formatted string.
	(WriteDPXImage): Fix colorspace mapping logic.  Was converting
	Cineon log to RGB when it shouldn't be.

2005-05-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (WriteDPXImage): Default to big-endian output.

	* magick/delegate.c (InvokePostscriptDelegate): Improved
	Ghostscript API-based error reporting and logging.

	* magick/attribute.c (GenerateEXIFAttribute): Extend EXIF
	knowledge a bit.  Pass more characters from EXIF_FMT_BYTE in case
	the byte stream contains nulls.

	* coders/dpx.c: Re-wrote the DPX read/write support in order to
	hopefully surmount problems noticed when testing with files sent
	to me.

	* wand/pixel_wand.c (PixelSetYellowQuantum): Wrong PixelPacket
	member was being set.  Thanks to Cristy for the heads-up.

	* magick/image.c (SetImageType): Revert change from 2005-03-12.
	Some coders require that when the image is set to Bilevel type,
	that it be PseudoClass.

2005-04-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* utilities/tests/convolve.sh: Add a convolution parameter.

2005-04-28 Glenn Randers-Pehrson <glennrp@glennrp.com>

	* magick/command.c: "IsGeometry() test was rejecting valid
	-convolve parameters.  Also, the image returned by ConvolveImage()
	was ignored.

2005-04-25 Glenn Randers-Pehrson <glennrp@glennrp.com>

	* coders/png.c: Initialize several variables to avoid new
	GCC 4.0.0 warnings.

	* coders/pnm.c: Defend against malicious "P7" files that try
	to set the colormap less than 256 bytes (bug fix from ImageMagick)

2005-04-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (WriteDPXImage): Fill out source information
	header.

	* Magick++: Added image leveling methods for Magick++.

2005-04-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* NEWS: Update with latest news.

	* magick/blob.c (WriteBlob): Move BlobStream write support to a
	subroutine for easier maintenance.

	* coders/dpx.c (ReadDPXImage): Support retrieving all DPX
	attributes as image attributes.
	(WriteDPXImage): Buffer writes for better performance on some
	platforms.

2005-04-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (WriteDPXImage): Re-write sample marshalling to be
	based on a series of tighter loops.  Results in a small
	performance increase.
	(ReadDPXImage): Re-write sample marshalling to be
	based on a series of tighter loops.  Results in a small
	performance increase.

2005-04-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/Xwindow.c (XDelay): Prefer use of select() over poll()
	since it is more portable.  MacOS-X has a poll() but it doesn't
	work right.

2005-04-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/magick_endian.h: Renamed from endian.h in order to avoid
	conflict with system headers.

2005-04-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/miff.c (WriteMIFFImage): Normalize image depth to 8/16/32.

	and 16-bit original test images.

	* coders/dpx.c (ReadDPXImage): If samples are log encoded, then
	set the image to CineonLogRGBColorspace.
	(WriteDPXImage): If image samples are log encoded, then mark DPX
	file as being log encoded.

	* magick/colorspace.c (TransformRGBImage): Support translation
	from log RGB to linear RGB based on Cineon guidelines.
	(RGBTransformImage): Support translation from linear RGB to log RGB.

	* magick/colorspace.h (enum CineonLogRGBColorspace): New
	enumeration to record that the RGB values are log encoded in a
	2.048 density range as defined for the Cineon Digital Film System.

2005-04-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c: Take advantage of ColorspaceTypeToString() and
	StringToColorspaceType() functions in implementation.

	* magick/colorspace.c (RGBTransformImage): Added support for
	converting to Rec 709 grayscale colorspace.
	(ColorspaceTypeToString): New function to translate from
	ColorspaceType enumeration value to a string.
	(StringToColorspaceType): New function to translate from a string
	to a ColorspaceType enumeration value.  * magick/colorspace.h
	(enum Rec601LumaColorspace): New enumeration to support the Rec
	601 grayscale colorspace.  This is the colorspace previously
	represented by GRAYColorspace. If GRAYColorspace is specified,
	then Rec601LumaColorspace is selected.
	(enum Rec709LumaColorspace): New enumeration to support the Rec
	707 grayscale colorspace.

2005-04-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (IdentifyImageCommand): Use +ping to force
	identify to read the image pixels.

	* magick/constitute.c (PingImage): Intentionally clear
	user/elapsed timer when ping is used on an image since the results
	are misleading.

	* magick/image.c (DescribeImage): Only display pixel read rate if
	the time accumulated is at least the timer's resolution.

	* magick/cache.c (OpenCache): Fix a memory resource leak noticed
	by Stefan v. Wachter <svwa-dev@mnet-online.de>.  This error with
	keeping track of resources may eventually cause GraphicsMagick to
	run slower and slower due to using disk-based images rather than
	memory-based images.

2005-04-07 Glenn Randers-Pehrson <glennrp@glennrp.com>

	* coders/png.c: encoder now accepts image->depth other than 8 and 16.

2005-04-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (WriteDPXImage): First pass at a new SMPTE268M-2003
	DPX writer.

2005-04-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/utility.c (AllocateString): Performance enhancement.
	(CloneString): Performance enhancement.
	(ConcatenateString): Performance enhancement.

2005-03-31 Glenn Randers-Pehrson <glennrp@glennrp.com>

	* coders/jpeg.c: revised EOF test.  It was rejecting good image
	files.  Needs more work.

2005-03-30 Glenn Randers-Pehrson <glennrp@glennrp.com>

	* coders/pnm.c (ReadPNMImage): Throw a "Corrupt Image" exception
	if EOF is encountered while reading scanlines in P1, P2, P3, or P4
	formatted images (P5 and P6 were OK).

2005-03-29 Glenn Randers-Pehrson <glennrp@glennrp.com>

	* coders/sgi.c (ReadSGIImage): Throw a "Corrupt Image" exception
	if EOF is encountered while reading scanlines.

2005-03-28 Glenn Randers-Pehrson <glennrp@glennrp.com>

	* coders/jpeg.c (ReadJPEGImage): Throw a "Corrupt Image" exception
	if EOF is encountered while reading scanlines.

	* coders/pcx.c (ReadPCXImage): Throw a "Corrupt Image" exception
	if EOF is encountered while reading pixels.

	similar features in the same area of the header.

	* magick/nt_base.c: Renamed wrappers for standard functions so
	that they have the prefix `NT`. Macros are used to apply the new

	file. Apparently libjbig parameters have changed. Setting l0
	parameter of jbg_enc_options to zero instead of -1 (like in
	jbigkit's pbmtools) solved the problem.

2005-03-07  Mike Chiarappa  <mikechiarappa@libero.it>

	* BCBMagick\magick\GM_magick.bpr: Updated to reflect changes since
	last update.
