* 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
percent symbol is supplied within the argument rather than at the
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.

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.

* 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.

* tests/Makefile.am: Extended read/write tests to include 10, 12,
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.

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>

if EOF is encountered while reading pixels.
2005-03-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/dpx.c (ReadDPXImage): First pass at a new SMPTE268M-2003
DPX reader.
* magick/bit_stream.h (WordStreamLSBRead): New function to parse
values from a stream which is defined by 32-bit words. Values are
read starting with the least significant bits.
2005-03-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/tiff.c (ExtensionTagsInitialize): Fix conditional use of
TIFFSetTagExtender().
2005-03-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/endian.c: Imported libtiff's swab.c since its functions
are so useful and well-tested.
* magick/utility.c (FormatSize): Extend to support incredibly
large sizes.
* magick/image.c (DescribeImage): Use GetTimerResolution() when
computing pixels-per-second rate in order to avoid computing
astronomical rates when the time consumed is too small to measure.
* magick/timer.c (GetTimerResolution): New function to return the
timer's resolution.
2005-03-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/pdf.c (WritePDFImage): Eliminate cause of annoying
warning when PDFs are read by Ghostscript 8.5.
2005-03-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

thread specific data.
(TIFFWarnings): Update to make thread safe via thread specific
data.
* magick/tsd.c (MagickTsdKeyCreate): New function to support
thread specific data.
(MagickTsdKeyDelete): ditto
(MagickTsdSetSpecific): ditto
(MagickTsdGetSpecific): ditto.
2005-03-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/image.c (ReplaceImageColormap): New function to replace
the image colormap with a user-provided one. Colormap indexes are
adjusted to point to identical colors in the new colormap.
* magick/nt_base.h: Reorganized a bit to cluster code supporting
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
names. This assures that there will not be conflicts if the library
is linked with a different package's wrapper functions.
2005-03-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/quantize.c (GrayscalePseudoClassImage): Moved to here
from image.c. Added support for is_monochrome.
2005-03-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* jp2: Updated Jasper library to version 1.701.0.
* magick/nt_base.c (NTGhostscriptFonts): Fixed a coding error
which was added when strcpy/strcat code was replaced with
strlcpy/strlcat. Ghostscript fonts were not being found.
* magick/constitute.c (ReadImage): Don't attempt to access image
members if image pointer is null. Oops!
2005-03-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/image.c (SetImageType): Bilevel image is not required to
be PseudoClass type.

* coders/png.c: Avoid attempting to write indexed PNG when
a color entry has more than one opacity level. The PNG format
supports this but GM's colormap does not, so erroneous files
were being written.
2005-03-09 Arne Rusek <zonk@matfyz.cz>
* magick/attribute.c (GenerateEXIFAttribute): Offset type
correction to fix loop termination if size_t type is not `long`.
2005-03-09 Alexander Yaworsky <yaworsky@users.sourceforge.net>
* coders/jbig.c (WriteJBIGImage): JBIG was writing an empty output
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>

2005-02-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/tiff.c (ReadTIFFImage): Read grayscale TIFFs as
DirectClass rather than promoting to PseudoClass. Fix improper
multiple repeated "disassociate" operations when reading planar
images which contain an alpha channel.

background if the image has a matte channel.
* magick/constitute.h (enum QuantumType): Eliminated
GrayInvertedQuantum and GrayInvertedAlphaQuantum which were added
since GraphicsMagick 1.1. Replaced this "inverted" gray
functionality with the grayscale_inverted flag in
ExportPixelAreaOptions and ImportPixelAreaOptions.
* magick/constitute.c (ExportImagePixelArea): Added an extra
parameter for passing seldom used options via an
ExportPixelAreaOptions structure.
