GraphicsMagick 1.1.11 ChangeLog |
2008-02-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- version.sh: GraphicsMagick 1.1.11 released.
- NEWS: Updated for release.
2008-02-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/xwd.c (ReadXWDImage): Eliminate integer overflow
vulnerability (IDefense 09.19.07).
- coders/xcf.c (ReadXCFImage): ditto
- coders/xbm.c (ReadXBMImage): ditto
- coders/dib.c (WriteDIBImage): ditto
- coders/dcm.c (ReadDCMImage): ditto
2008-02-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (WriteTIFFImage): The RFC 2301 specification for
Internet FAX recommends LSB2MSB fill order so document that.
2008-02-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (WriteTIFFImage): Use '-define
tiff:fill-order={msb2lsb|lsb2msb}' to control TIFF bit fill order.
(WriteTIFFImage): Endian option (-endian) now controls TIFF byte
endian order rather than bit fill order.
2008-01-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (SetImageInfo): Successfully read existing file
names in the form file[123] which were failing to read since they
appear to be a valid sub-image specification.
2008-01-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/utility.c (ExpandFilenames): If a filename appears to
contain a wildcard specification, first check to see if there is
file matching the unexpanded wildcard prior to engaging in the
slow task of wildcard expansion. Without this fix, expanding the
command line takes a very long time if there are a huge number of
files in the directory, and some file names appear to contain
wildcard specifications. Inspired by SourceForge bug reports [
1878992 ] "literal square brackets in file name cause large delay"
and [ 1783209 ] "converting runs slowly when subimage is
specified", but this might not be the complete fix for the
problem.
2008-01-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c (VersionCommand): Include a "Large Memory" item
in the Feature Support list.
- coders/png.c (RegisterPNGImage): Remove reference to dead PNG
ftp site.
- VisualMagick/configure/configure.cpp (InitInstance): Remove
project dependency on dxguid.lib (Direct-X).
2008-01-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c (DisplayImageCommand): No longer default to
reading standard input if stdin fails isatty() test. This
behavior was causing failure to launch from Gnome and it is
difficult to work around the issue from within a .desktop file.
(AnimateImageCommand): No longer default to
reading standard input if stdin fails isatty() test.
2007-12-31 Glenn Randers-Pehrson <glennrp@comcast.net>
- coders/png.c (ReadOnePNGImage): Ensure that depth is handled
correctly in Q8 build with 16-bit PNG files. Addresses
SourceForge bug 1859467 "16 bit per channel pngs broken". This
bug was already fixed in CVS head.
2007-12-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

width and height values. Validate width and height values.
- coders/bmp.c (ReadBMPImage): Use appropriate sized cast for BMP
width and height values.
- coders/sun.c (ReadSUNImage): Properly report SUN image depth.
- magick/image.c (RGBTransformImage): Use a better rounding
algorithm when converting to HSL/HWB colorspaces. Add missing
break HWB colorspace was used rather than HSL.
- magick/image.c (TransformRGBImage): Add missing break
statement. HWB colorspace was used rather than HSL.
- magick/gem.c (TransformHSL): Avoid GCC opimization bug on
Opteron which caused wrong results. Ensure that returned values
fall within bounds 0.0 to 1.0.
(TransformHWB): Avoid GCC opimization bug on
Opteron which caused wrong results. Ensure that returned values
fall within bounds 0.0 to 1.0.
- PerlMagick/t/ttf/read.t: Relax strictness quite a bit for TTF
read tests in order to allow somewhat different FreeType output.

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

- 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 and the X.org server doesn't properly keep track of the
resource allocation.

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

decoder when calculating the shift r/g/b values and the mask is
set to zero.
2005-05-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- version.sh (PACKAGE_VERSION): Release version 1.1.6.
- 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.

2005-04-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/xwindow.c (XDelay): Prefer use of select() over poll()

work right.
2005-04-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/cache.c (OpenCache): Fix a memory resource leak noticed
by Stefan v. Wachter <svwa-dev@mnet-online.de>. This error with

run slower and slower due to using disk-based images rather than
memory-based images.
2005-04-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/utility.c (AllocateString): Performance enhancement.

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.

has an over-sized colormap. Was writing on unallocated heap memory.
2004-12-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/gem.c (Modulate): Hue argument now represents a rotation
from -180 degrees to +180 degrees expressed as an argument of 0 to
2.0 (1.0 for no change). Note that this change also effects the
-modulate argument and the Magick++ modulate method(). This change
is made because the previous hue adjustment strategy only
succeeded in corrupting the image.
2004-12-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/nt_base.c (opendir): Ensure that data may not overwrite
the stack.

2004-07-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- tiff/libtiff/tif_lzw.c: Incorporated TIFF LZW compression
support.
- lcms: Merged in lcms 1.13 from CVS HEAD.
2004-07-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- version.sh (CVS_BRANCH_TAG): Record the CVS branch tag that
source package is obtained from.

internally.
2004-07-09 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/bmp.c (ReadBMPImage): Removed if-test on reading
red_mask, green_mask, and blue_mask. These are only *valid*

- Enable LZW compression by default.
2004-07-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

copied to a null pointer. Now memory is allocated as required
prior to a copy.
Ensure that all unimplemented functions return a proper error
report.
2004-06-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c (MogrifyImage): For -units, don't reset

report an error if the image does not contain a valid resolution.
- coders/pcx.c (WritePCXImage): Support writing large PCX files.
(WritePCXImage): Ensure that UndefinedResolution is handled
properly. Avoid round-off error for centimeter based resolution.
- magick/command.c (MogrifyImage): When setting image units, also
adjust existing image x_resolution and y_resolution so that
existing image resolution is not trashed.
- configure.ac: Look for mozilla by default rather than netscape.
2004-06-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
2004-06-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/module.c: (InitializeModuleSearchPath): Evaluate and cache
module search path.
(FindMagickModule): Use cached module search path.
(OpenModules): Load all modules rather than just the modules in
the directory where the LOGO module is found. Besides allowing
user-provided modules in non-GraphicsMagick directories to be
loaded, this allows the "moby" shared build to load additional
modules via OpenModules.
- GraphicsMagick.spec.in: Install *-config scripts with mode 755
rather than default 644.
- magick/type.c (ReadTypeConfigureFile): Determine location of
Ghostscript fonts only once in order to improve performance.
- magick/nt_base.c (NTGhostscriptFonts): Properly determine
Ghostscript font location for Ghostscript 8.0 and later.
2004-05-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Magick++ needs to be built as a static library
under Cygwin and MinGW since C++ exceptions don't work otherwise.
Be more assertive about that.
- magick/nt_base.h: Avoid conflict with ssize_t definition under
MinGW.
2004-05-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- ltmain.sh: Fix to allow exe wrapper to work under MinGW.
- wand/magick_compat.c (QueryMagickColor): Fixed wrong DLL export.
- wand/magick_wand.c: Fixed some wrong DLL exports.
2004-05-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c (ConvertUsage): Usage missed -operator.
(MogrifyUsage): Usage missed -operator.
2004-05-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/enhance.c (NegateImage): If image has a clip mask,
then force image to DirectClass so clip mask takes effect.
2004-05-15 Vladimir Lukianov <lvm@integrum.ru>
- magick/image.c (SetImageOpacity): Ensure that image is
DirectClass. If specified opacity is TransparentOpacity, then
replace existing opacity with TransparentOpacity.
2004-05-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/utility.c: Released 1.1.1.
2004-04-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- utilities/Makefile.am (check): Change geometry arguments which
were expressed as 0.0xVAL to avoid the problematic Linux scanf
feature back to 0xVAL.
2004-04-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/utility.c (GetMagickDimension): New function to replace
occurances of scanf(geometry,"%lfx%lf",&w,&h) since Linux scanf()
and strtod() misbehave for strings that start with "0x". The Linux
versions always treat 0x as the start of a value expressed in hex
and can't be forced to read the leading value as a double. This
function has been applied globally to replace the problem scanf's.
2004-04-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/version.h.in: Make it clear in the -version output that a
mutitude of copyrights and licenses apply to this software.
- magick/utility.c (GetPathComponent): Avoid strncpy() of
overlapping regions.
- magick/command.c (DisplayImageCommand): Eliminate double-free
of resource_info->image_geometry.
(DisplayImageCommand): 'display' was improperly requiring at least
one argument (bug was added yesterday).
2004-04-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- utilities/gm.c (main): Default usage message wasn't right for
aliased utility.

compatibility links to emulate ImageMagick commands.
- magick/command.c: Ensure that each sub-command responds to -help
and -version appropriately.
- utilities/gm.c (main): Invoke appropriate sub-command if gm is
executed under a traditional alternate name such as "convert". The
user may create hard or symbolic links from 'gm' to a traditional
ImageMagick utility name (or just copy 'gm' to the desired
sub-command name) in order to be 100% command-line compatible with
ImageMagick 5.5.2. This is necessary in order to work with
existing software designed to execute ImageMagick utilities.
2004-04-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/compress.c (Ascii85Tuple): Fix an encoding bug noticed on
DEC Alpha.
2004-04-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

produced an output file since sometimes it reports success after
it has spewed an error message and has produced no output.
2004-04-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/compress.c (HuffmanEncode2Image): Avoid out of bounds
array access.
2004-04-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Fix minor shell syntax error (used ==).
2004-04-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- version.sh (PACKAGE_VERSION): Release version 1.1.
Bumped revision to 1.1.1.
- magick/studio.h: Disabled use of Windows message lookups
entirely since this doesn't seem to work for programs. It
probably only works for DLLs like ImageMagickObject.
- magick/delegate.c (ListDelegateInfo): Don't get stuck in a loop
if fprintf() returns zero.
2004-04-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/*/*.bat: Add .exe to exe file names in order to
ensure that the executable is executed rather than something else
(such as a batch script).
- magick/locale.c: Only use Windows resource message lookup for
the DLL build since it doesn't seem to work for static
executables.
- magick/utility.c (SetClientPath): Ensure that client path is
null terminated.
(SetClientFilename): Initialize default client filename to ""
rather than "gm.exe" and ensure that filename is null terminated.
(SetClientName): Ensure that client path is null terminated.
- magick/blob.c (GetConfigureBlob): Enable logging the load of
log.mgk
- magick/log.c: Re-designed logging initialization in order to
avoid the "chicken and the egg" snafu. This allows logging the
initialization of the logging subsystem.
2004-04-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/bin/log.mgk: Add comments to help document usage.
- config/log.mgk: Add comments to help document usage.
- magick/utility.c (IsAccessible): Use access() rather than stat().
(IsAccessibleNoLogging): Use access() rather than stat().
(IsDirectory): Implemented return status according to existing API
documentation.
(GetExecutionPathUsingName): Complete re-write in order to minimize
path computation logic and fix failure with partial paths.
2004-03-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- doc/options.imdoc: Add "Color" to the arguments available for -list.
2004-03-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- version.sh (PACKAGE_CHANGE_DATE): Updated version to 1.1Beta3
- magick/nt_base.c (NTSystemComman): Have not been successful with using
MsgWaitForMultipleObjects() reliably, so back out usage of it for
now.
- magick/fx.c (ConvolveImage): Support convolution in CMYK
colorspace.
2004-03-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- version.sh (PACKAGE_CHANGE_DATE): Update release to 1.1Beta2.
- magick/constitute.c (ReadImage): Ignore errors of type
ConfigureError when loading modules so that error report can still
report the familiar "No delegate for this image format" message
while still being able to report problems with loading a module if
it was found. This is a compromise which reports useless messages
when the modules are not found at all, but I can't think of a way
around it.
- magick/nt_base.c (NTSystemComman): Adjust
MsgWaitForMultipleObjects() arguments to wait for object to be
signaled only (FALSE) rather wait for object to be signaled as
well as an input event received(TRUE). It seems that process
status changes do not result in an input event, so the call was
deadlocking.
- magick/constitute.c (ReadImage): If module loading reported an
error, ReadImage immediately returned an error rather than trying
to use a delegate defined by delegates.mgk.
2004-03-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- version.sh: Updated version to 1.1Beta1
2004-03-24 Mike Chiarappa <mikechiarappa@libero.it>

2004-03-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/plasma.c (ReadPlasmaImage): srand() is already invoked by
InitializeMagick() so don't call it here.
- configure.ac: Check for rand_r().
- magick/tempfile.c (ComposeTemporaryFileName): The full range of
safe characters was not being used, thereby limiting the number of
unique temporary file names available.
2004-03-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (GetImageStatistics): New function to obtain
image statistics (minimum, maximum, mean, variance, and standard
deviation).
(DescribeImage): Include image channel statistics in verbose
output.
2004-03-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

a bit of error for Q:32.
- magick/constitute.c (DispatchImage): Be more careful when
rounding pixel intensity.
(ConstituteImage): Be more careful when converting float and
double to Quantum.
- magick/composite.c (CompositeImage): Fix Multiply composite
operator for Q:32 build (was all black image).
(CompositeImage): Tidied up the documented composite operators so
the implementation is easier to understand.
- PerlMagick/t/ttf/read.t: Set a desired label size so output
image should be the same size as the reference image even if the
FreeType type hinter is disabled.
- magick/annotate.c (RenderFreetype): Improve outline bounding box
computation accuracy.
2004-03-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/t/x/write.t: Don't test X11 if DISPLAY is not set.
- PerlMagick/t/x/read.t: Don't test X11 if DISPLAY is not set.
2004-03-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/Makefile.am: Removed some apparently unnecessary library
dependencies.
- Makefile.am (windows-src): Added a way to generate a Windows
source zip file.
2004-03-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c: The -operator command now supports
floating-point and percent of range arguments.
2004-03-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c: Added support for -operator command with
syntax "-operator channel operator rvalue" which applies a
arithmetic or bitwise operator to a specified image channel
or all channels.
2004-03-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/t/filter.t: Fix Solarize test case.
- PerlMagick/t/wmf/read.t: Added another WMF test case.
- coders/wmf.c: Resolve WMF rendering bug with black color.
- magick/utility.c (StringToArgv): Free argv data prior to error
return.
2004-03-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/jpeg.c (WriteJPEGImage): If image_info->colorspace is set
to GRAYColorspace then make sure that image is in a gray
colorspace.
- magick/image.c (TransformRGBImage): If colorspace is already an
RGB type (RGBColorspace, GRAYColorspace, or TransparentColorspace),
then simply return. Do *not* set image->colorspace to RGBColorspace
since this potentially loses a valuable setting.
2004-03-10 Peter Boos <pedib@colorfullife.com>
- magick/annotate.c (RenderFreetype): If DrawAnnotation is called
with a string containing only one character and this character is
not recognized by the TrueType engine, a crash occured due to the
failure of FT_Load_Glyph. The failure caused an uninitialized
glyph.image pointer to be used by FT_Done_Glyph() later in the
code. The solution is to initialize the glyph.image pointer to
null.
2004-03-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (QuantumOperatorRegionImage): Properly handle
over and underflow of arithmetic operators.
- magick/draw.c (DrawGetFillOpacity): Use fill opacity, and invert
opacity range so it is 0.0 to 1.0 (was acting like transparency).
(DrawSetStrokeOpacity): Validate range of stroke_opacity.
(DrawSetFillOpacity): Save value to context->fill.opacity and
validate the range of fill_opacity.
- magick/image.c (QuantumOperatorImage): New function to apply an
arithmetic or bitwise operator to the pixel quantums in an image.
(QuantumOperatorRegionImage): New function to apply an arithmetic
or bitwise operator to the pixel quantums in an image region.
- magick/image.c (IsImagesEqual): Re-implemented using the new
pixel iteration functions as a proof of concept.
- magick/pixel_iterator.h: Added some pixel iteration functions in
order to make it easier to implement algorithms which only need to
iteratively access pixels in a region. These functions are not
part of the API yet so their interface should be considered
unstable.
- doc/GNUmakefile: Rename Makefile to GNUmakefile since it relies
on GNU make extensions.
2004-03-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/constitute.c (ConstituteImage): Add support for 'T'
(transparency) and 'O' (opacity) map types. Simplify
implementation.
(DispatchImage): Add support for 'T' (transparency) and 'O'
(opacity) map types. Simplify implementation.
- config/delegates.mgk.in: Quote delegate command names so
that they can contain embedded spaces.
- VisualMagick/bin/delegates.mgk: Quote delegate command names so
that they can contain embedded spaces.
- coders/tiff.c (WriteTIFFImage): Use the libtiff default endian
mode when writing TIFF rather than forcing MSB2LSB bit order.
(ReadTIFFImage): Enable reading in MSB2LSB bit order (better for
our byte-level parsing), enable memory mapping, and enable strip
chopping. Memory mapping and strip chopping are probably enabled
by default.
- magick/nt_base.c (NTSystemComman): Use
MsgWaitForMultipleObjects() rather than WaitForSingleObject() in
order to avoid possible deadlock when application code directly or
indirectly creates windows.
2004-02-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/animate.c (XMagickCommand): URL should point to
http://graphicsmagick.org/.
- magick/display.c (XMagickCommand): URL should point to
http://graphicsmagick.org/.
- magick/image.c (DisplayImages): Changes to fix memory leaks in
X11 commands had bugs which seriously broke DisplayImages. Now
DisplayImages works properly again.
- magick/xwindow.c (XDestroyResourceInfo): New function to destroy
XResourceInfo.
- coders/x.c (WriteXImage): Implement based on DisplayImages().
(RegisterXImage): Always register X coder, but with read/write
support disabled if X11 not available.
2004-02-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c (ImportImageCommand): Eliminate memory leaks.

better integration with gm command.
- magick/display.c (XDisplayImage): Display was leaking memory
like a sieve. Now it doesn't.
- magick/memory.c (CloneMemory): Computation for when it is safe
to use memcpy() was incorrect. Use memmove() rather than
backwards-copy loop.
- Makefile.am ($(DIST_ARCHIVE_SRPM)): Added rules to build a
source RPM.
- configure.ac: Search for 'buildrpm' or 'rpm' programs in order to
support creating RPM packages on a system which has RPM installed.
- version.sh (PACKAGE_VERSION): Changed snapshot release naming so
that there is only one dash in the name and the snapshot date is
prefixed with '0' to assure proper directory sorting. This allows
snapshot naming to be acceptable to RPM. The snapshot package
name is now similar to GraphicsMagick-1.1.020040218.tar.bz2
2004-02-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/xwd.c (RegisterXWDImage): Always register XWD, but only
register read/write methods if it is supported.
- wand/magick_wand.c: Synchronized with latest ImageMagick API
changes.
2004-02-16 Lars Ruben Skyum <lars.skyum@stibo.com>

for CMYK images.
(VerticalFilter): do process K channel for CMYK images.
2004-02-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tga.c (ReadTGAImage): Fix matte channel handling. For
16-bit packets, use integer rather than floating point. Return
gray images as PseudoClass and set is_grayscale flag. Add
logging.

DirectClass. Ensure that matte channel is initialized if
necessary. Include background color in is_grayscale evaluation.
- magick/gem.c (GenerateNoise): Scale noise to range of quantum.

Jasper options using -define.
2004-02-13 Peter Boos <pedib@colorfullife.com>
- coders/wmf.c (util_draw_arc): Fixes to improve handling for pie,
arc, and chord. These fixes produce correct output for
wmf/examples/fjftest.wmf, but it is not known if they are correct
for all cases.
2004-02-12 Tim Hunter <cyclists@nc.rr.com>
- magick/profile.c (SetImageProfile): Bug fixes.
2004-02-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

C files.
- magick/constitute.c (MapQuantumType): Fix spurious comma in
enum definition.
- magick/blob.c (GetBlobStreamHandler): Apparently return type can
not be const.
2004-02-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Check for Windows fonts under
/usr/X11R6/lib/X11/fonts/truetype (XFree86 standard location?).
- coders/jp2.c (WriteJP2Image): Support providing a compression
rate value (range 0.0 to 1.0) using command line syntax similar to
'-define jp2:rate=0.5'. In Magick++ this option may be accessed
similar to image.defineValue("jp2","rate","0.5");
- magick/command.c (DisplayImageCommand): Exit status was inverted
so 'gm display' was returning 1 for successful commands, and 0 for
failures.
(AnimateImageCommand): Exit status was inverted so 'gm animate'
was returning 1 for successful commands, and 0 for failures.
2004-02-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

channel unless image->matte is True.
2004-02-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/png.c (UnregisterPNGImage): Destroy PNG semaphore.
- magick/image.c (SetImageInfo): Since we don't know what the
"IMPLICIT" specifier is supposed to do, support for it is
removed. Perhaps by removing support for it, we will be reminded
why it exists.
- magick/magick.c (DestroyMagickInfo): Invoke
UnregisterStaticModules().
(GetMagickInfo): Remove registration for "IMPLICIT" format since
its purpose is presumed bogus.

- coders/wpg.c (ExtractPostscript): Use DestroyBlob.
- magick/blob.c (DestroyBlob): New function. Similar to
DestroyBlobInfo except that it requires an Image * argument and
zeros the blob pointer. This one is preferred for use over
DestroyBlobInfo.
2004-01-27 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/png.c: Add DestroyBlobInfo() calls to stop memory leak when
processing JNG datastreams.

make C++ Happy.
- coders/tiff.c: Adjust for bitstream API function renaming.
- magick/bit_stream.h: Rename BitStreamRead() to
BitStreamMSBRead() to indicate that it reads most significant bytes
first ("big endian" order). Rename BitStreamWrite() to
BitStreamMSBWrite() to indicate that it writes most significant
bytes first ("big endian" order).
- wand/magick_wand.c: Updated to lastest ImageMagick API.
2004-01-26 Mike Chiarappa <mikechiarappa@libero.it>
- magick/stream.c: (SetPixelStream) removed "const" from definition of
local variable [StreamHandler stream]. Borland C++Builder compiler signal
error "Cannot modify a const object".
2004-01-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (TIFFMapBlob): Allow libtiff to access memory
mapped file (or BLOB in memory) directly. This provides a small
performance increase.
- magick/constitute.c (ReadImage): If a .mpc file is a temporary
file, then be sure to remove the associated .cache file when
removing the .mpc file.
- magick/log.h (LogEventType): ExceptionEventMask now maps to
WarningEventMask|ErrorEventMask|FatalErrorEventMask so that
'-debug exception' works again.

blob which is not open (in UndefinedStream state).
(BlobInfo): The definition of BlobInfo is now private to blob.c.
(StreamType): The StreamType enumeration is now private to blob.c.

handler.
(GetBlobStreamType): This function is removed entirely.
(BlobIsSeekable): New function to test if SeekBlob will work
properly for this blob type.

(ThrowWriterException): Ditto.
(ThrowWriterException2): Ditto.
(ThrowWriterException3): Ditto.
- magick/tempfile.h (ThrowReaderTemporaryFileException): Ditto.
(ThrowWriterTemporaryFileException): Ditto.
- coders/dps.c,coders/jpeg.c, coders/meta.c, coders/mvg.c,
coders/png.c, coders/tiff.c, magick/constitute.c, magick/stream.c:
Use new blob accessor functions.
- magick/cache.c (OpenCache): For Windows, set the sequential
access flag in all cases. Maybe it will make a difference.
2004-01-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/blob.c (GetConfigureBlob): Don't check Windows registry
if MagickLibConfigPath or MagickShareConfigPath is defined.

- rungm.sh.in: Translate environment paths to Windows format when
running under MinGW.
- magick/nt_base.c (mmap): Re-wrote mmap emulation to support
64-bit file offsets and to support anonymous mapping.
(msync): A crude emulation of Unix msync().
- acinclude.m4 (GM_FUNC_MMAP_FILEIO): Change result define from
HAVE_MMAP to HAVE_MMAP_FILEIO so that it doesn't conflict with
Autoconf standard definition.
2004-01-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/cache.c (OpenCache): While allocating the pixel cache
from the heap, reserve enough memory to contain a full PseudoClass
image in order to reduce the chance that there will be a memory
allocation failure while processing the image. This also avoids
the possibility that the image pixels will be block-copied to a
new location due to heap memory fragmentation. If there is
insufficient heap memory (malloc() fails), then a disk-based pixel
cache will be used.
- coders/wpg.c: Backed out Jaroslav Fojtik's patch from 2004-01-13
because WPG was failing PerlMagick's existing WPG read test.
2004-01-16 Mike Chiarappa <mikechiarappa@libero.it>

BIG-KIT 1.5, libpng 1.2.5, libwmf 0.2.8.2, and zlib 1.2.1.
- Verified Windows static and DLL compilation with Visual C++ 6.0.
- Makefile.am: Update to automake 1.8.2.
- coders/gif.c (WriteGIFImage): Use ColorMatch rather than
FuzzyColorMatch when comparing colormap entries.
2004-01-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/profile.c: Needed to include "magick/profile.h" in order

dealing with embedded image profiles.
- magick/profile.c: New source file to contain functions for
dealing with embedded image profiles.
- Makefile.am (DISTDIRS): Distribute TclMagick subdirectory.
2004-01-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- wand/magick_wand.c: Ported over the latest ImageMagick Wand API
updates. Note that a comment now says that the Wand API will not
be finished until around 4th quarter of 2004. This represents a
1-1/2 year slip from the original estimate!
2004-01-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (IsImagesEqual): Simplified implementation.
- magick/magick.c: Removed some unused code.
- contrib/win32/ATL7/ImageMagickObject/ImageMagickObject.cpp
(IDispatch): Comment out InitializeSemaphore() so code compiles.
- libtool.m4: Updated to 2004-01-03 version of CVS libtool. This
should fix configure problems under AIX and IRIX.
2004-01-03 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/sgi.c: opacity channel was lost when writing grayscale
SGI images. See bug report in magick-users list.
2003-12-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/annotate.c (RenderFreetype): Ensure that image storage
class is set to DirectClass. Text rendering was not working
properly on top of PseudoClass images.
- magick/map.c (MagickMapRemoveEntry): Logic didn't properly
handle removing entry in list.
- configure.ac: Added --enable-efence option to enable memory
debugging using Electric Fence.
2003-12-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- tests/maptest.c (main): Extended test to add an entry to the
list after an entry has already been removed.
- magick/image.c (ColorspaceTypeToString): Add support for LAB
colorspace.
- magick/map.c: Added signature members to all structures and
added assertions to ensure that the signature == MagickSignature
prior to use. MagickMapAllocateObject now initializes the object
reference count to one, and MagickMapDestroyObject decrements it
in order to be more correct even though the object reference count
is not actually used yet.
(MagickMapCopyString): Preserve a null argument, and use
AcquireString since it doesn't enlarge the string storage.
(MagickMapCopyBlob): Preserve null blobs.
- configure.ac: Search for the shmctl() function. Under current
Cygwin, this is hiding in -lcygipc.
2003-12-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/composite.c: Fixed the composite operator list in the
CompositeImage documentation.
- www/api/types.html: Corrected list of composition
operators. Sometime prior to the creation of GraphicsMagick, the
"Replace" composite operators were renamed to be "Copy" composite
operators. Thanks to David Relson for bringing this problem to
our attention.
- PerlMagick/Magick.xs: Added "LAB" to colorspace types.
- magick/image.h (enum ColorSpace): Add LABColorspace enumeration.
- wand/magick_wand.h : Add some compatibility definitions to
translate from ImageMagick enumerations to existing GraphicsMagick
enumerations.
2003-12-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/annotate.c: Use header synonyms defined by FreeType's
ftheader.h (included via <ft2build.h>) to include FreeType headers.
This will presumably be more portable in the future.
- configure.ac: <ft2build.h> is an optional prerequisite for
<freetype/freetype.h> and <libwmf/ipa.h> so include it when
testing for these headers.
- magick/annotate.c: Include <ft2build.h> if it is available.
2003-12-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- wand/wandtest.c: Ported from latest ImageMagick version.
- wand/drawing_wand.c: Adapted to be compatible with latest
ImageMagick version.
- wand/pixel_wand.c: Adapted to be compatible with latest
ImageMagick version.
- wand/magick_wand.c: Ported from latest ImageMagick version.
- magick/image.h (Image): Members color_profile, iptc_profile,
generic_profile, and generic_profiles are now deprecated and
private although they continue to work as before. Please migrate
existing code to use the GetImageProfile and SetImageProfile
functions since these members will eventually be removed.
- magick/image.c (GetImageProfile): New function to retrieve an
image profile. Return value differs from similarly named
ImageMagick method since the ImageMagick approach assumes a
particular storage method.
(SetImageProfile): New function to add (or remove) an image
profile. Does not execute CMS color profiles.
- magick/cache.c (SetImageVirtualPixelMethod): Return unsigned int to
make the Wand implementation happy.
- magick/image.c (TransformColorspace): Return unsigned int to
make the Wand implementation happy.
(SetImageType): Return unsigned int to make the Wand
implementation happy.
- magick/draw.h, magick/draw.c: Substitute 'unsigned long' in
place of 'size_t' in interfaces so that the draw API is not
sensitive to the definition of _LP64.
- locale/C.mgk: Added new messages required by Wand library.
- magick/error.c (ExceptionSeverityToTag): Add tag translations
for the WandWarning, WandError, & WandFatalError enumerations
- magick/error.h (enum ExceptionType): Add WandWarning, WandError,
& WandFatalError enumerations to ExceptionType for ImageMagick
API compatibility.
- magick/image.h (enum ChannelType): Add an 'AllChannels'
enumeration to the ChannelType enumeration for ImageMagick
API compatibility.
2003-12-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick, tests: Adjusted allowed error values for tests based
on new error computation arithmatic. Some tests were left failing
since the operation they test provides results which are
unreasonably inaccurate, or obviously broken.
2003-12-17 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/jpeg.c: Changed "JPEG:preserve-settings from a key/value
pair to a simple flag. Save and restore attributes when
"-define JPEG:preserve-settings" appears on the commandline. Use
"+define JPEG:preserve-settings" to unset the flag.
2003-12-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/wmf.c: Include <ft2build.h> if it is available since some
libwmf installs don't work unless it is included before the libwmf
API headers.
- configure.ac: Check for <ft2build.h>.
2003-12-16 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/jpeg.c: Changed stored jpeg quality attribute from
[jpeg-quality] to JPEG-Quality. Added attributes JPEG-Colorspace
and JPEG-Sampling-factors. Added code to save and restore
these attributes when "-define JPEG:preserve-settings=yes" is
present in the comandline. Quality is restored if the input
was a JPEG and the quality was preserved. Sampling factors
are restored if the input was a JPEG, sampling factors were
preserved, and the colorspace for the output file is the same
as that of the input file.
2003-12-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- TclMagick/source/configure.ac: Add an initial TclMagick
configure-based build environment based on a template and macros
from the Tcl project. I recall that while the extension does build,
it is possible that it is not properly registered as a module to Tcl.
2003-12-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (IsImagesEqual): Properly compute error distance
vectors. Math was missing the necessary sqrt call. Also,
pre-normalize the error differences to 1.0 in order to reduce the
storage size required to store the summation of error values.
- PerlMagick/t/composite.t: Update Minus and Xor reference images.
- magick/composite.c (CompositeImage): Incorporated fixes from
ImageMagick for XorCompositeOp, PlusCompositeOp, and
MinusCompositeOp. Thanks to John Cristy for bringing the need for
these fixes to our attention.
- magick/image.h (RoundToQuantum): Added missing parenthesis.
2003-12-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- doc/environment.imdoc: Document MAGICK_CODER_MODULE_PATH and
MAGICK_FILTER_MODULE_PATH.
- rungm.sh.in: Pass MAGICK_CODER_MODULE_PATH and
MAGICK_FILTER_MODULE_PATH in the environment so modules build may
be tested without first being installed.
- magick/module.c (FindMagickModule): Use the
MAGICK_CODER_MODULE_PATH environment variable to specify a search
path for coder modules. Use MAGICK_FILTER_MODULE_PATH to specify
a search path for filter modules.
- Makefile.am: Updated to Automake 1.8.
(install-exec-perl): Fixes which achieve a successful
'make distcheck' for the first time in *Magick history.
- configure.ac: Set scripts to executable.
2003-12-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Makefile.am (uninstall-data-html): Pathnames were computed
incorrectly so documentation directories were being left behind.
- configure.ac: --without-frozenpaths is now the default. This
helps 'make distcheck' work and makes the package more portable.
Path to gm was being incorrectly frozen when --without-frozenpaths
was specified.
- magick/delegate.c (ReadConfigureFile): Validate delegate paths
prior to substitution.
- rungm.sh.in (top_builddir): Use a more reliable scheme for
computing location of source and build directories.
- magick/Makefile.am: Improve include directory computation logic.
- configure.ac: Don't override includedir. Pass user-supplied LIBS
to the linker.
2003-12-08 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/jpeg.c: store JPEG quality as "[jpeg_quality]" attribute.
2003-12-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- rungm.sh.in: New script to support executing uninstalled
executables.
- magick/blob.c (GetConfigureBlob): New MAGICK_CONFIGURE_PATH
environment variable allows the user to specify the search path
for configuration (.mgk) files.
2003-12-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- index.html: Added a table showing current stable release and
development version.
2003-12-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- doc/options.imdoc (use): Describe the syntax of the -process
argument.
- acinclude.m4 (AC_CHECK_CC_OPT): Add quoting in AC_CHECK_CC_OPT
definition. Change suggested by Patrick Welche
2003-12-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/magick.c (GetMagickInfo): Fix preprocessing logic error
which caused moby shared library build to not register static
modules.
2003-12-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/module.c (ExecuteModuleProcess): Add some logging.
- magick/static.c (ExecuteStaticModuleProcess): Add some logging.
2003-11-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/installer: Add optional build support for LZW.
- wand/Makefile.am: Add AUTOMAKE_OPTIONS.
- configure.ac: Update to Autoconf 2.59.
2003-11-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/installer/inc/tasks-install-perlmagick.isx: Update
to reflect that the next release will use ActivePerl 5.8.1 Build
807.
- VisualMagick/installer/inc/files-configs.isx: Updated the source
locations for the .mgk files. Install modules.mgk into the config
directory rather than the modules directory.
- configure.ac: Fixes to work with latest CVS libtool.
- libtool.m4: Update to latest CVS libtool.
- magick/modules.c, magick/static.c (ExecuteStaticModuleProcess):
Fix conditional compilation logic so that "moby" shared library
build works again.
- magick/compress.c, magick/mac.c: Use existing SaveImageText and
LoadImageText global constants rather than separate defines.
2003-11-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Update to Autoconf 2.58.
- Makefile.am: Update to Automake 1.7.9.
2003-11-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/draw.c (DrawComposite): Base64-encoded image was not
being deallocated. Bad memory leak.
2003-11-03 Mike Chiarappa <mikechiarappa@libero.it>
- BCBMagick: Updated installation procedure. Please read
BCBMagick/readme.txt for details.
2003-11-03 Mike Chiarappa <mikechiarappa@libero.it>
- BCBMagick: Released DLL Version. Please read BCBMagick/readme.txt
for details about installation and/or use.
2003-11-03 Lars Ruben Skyum <lars.skyum@stibo.com>
- magick/utility.c (GetPathComponent): Added x, X, and +
characters to list of legal characters in subimage
specifications. Required by raw RGB image reader which accepts the
syntax "image.rgb[100x100+50+50]". Thanks to John Cristy for
catching that one.
2003-11-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/locale.c (GetLocaleMessageFromID): Fix ID range checking
logic.
2003-10-30 Lars Ruben Skyum <lars.skyum@stibo.com>
- coders/jpeg.c: changed to not write gray CMYK images as
grayscales. That would not be a valid optimization.
- magick/color.c (IsGrayImage, IsMonochromeImage): Changed to
never return true for CMYK images. Separated images get wrong
colors when optimized to grayscales based on what these two
functions return. Gray and CMYK are two different color spaces.
- magick/nt_feature.c (NTIsMagickConflict): changed to accept
colon as part of the magick string, consistent with the way the
function is used.
- magick/utility.c, magick/utility.h (ExpandFilenames,
GetPathComponent): Fixed filename glob expansion. Added handling
of filename prefix-magick and sub-image specification to
GetPathComponent. Sub-image specification takes precedence over
any filename patterns.
2003-10-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/static.c (ExecuteModuleProcess): Renamed from
ExecuteStaticModuleProcess. Only compiled if SupportMagickModules
is not defined.
- magick/type.c (GetTypeBlob): Eliminated function.
(ReadTypeConfigureFile): Use GetConfigureBlob() rather than
GetTypeBlob().
- magick/module.c (GetModuleBlob): Eliminate this function since
modules.mgk is now installed under
${prefix}/share/GraphicsMagick-version/config so
GetConfigureBlob() may be used.
(lt_dlexit, etc.) Eliminate fake libltdl function wrappers used
for the static build.
(DestroyMagickModules): Added a new destroy function (simply
invokes DestroyModuleInfo()).
(GetModuleList): Learn where modules live by using
FindMagickModule() to locate the LOGO module rather than by using
the location of modules.mgk. This is necessary since now
modules.mgk may be seperate from the modules.
(GetModuleBlob): Eliminated function.
(InitializeMagickModules): New function to safely initialize the
module loader.
(OpenModule): Added logging messages.
(OpenModules): Added logging messages.
(ReadModuleConfigureFile): Use GetConfigureBlob() rather than
GetModuleBlob().
Totally eliminated the rat's-nest of conditional code dependent on
SupportMagickModules. Now all the code in module.c is dependent
on #if defined(SupportMagickModules).
- magick/magick.c (DestroyMagick): Invoke DestroyMagickModules().
(GetMagickInfo): #ifdef chunks of code which exist to support the
modules-build rather than forcing the module loader to pretend
that modules are being used when they are not. Pass module loading
exceptions back to the user rather than discarding them.
(GetMagickInfoArray): Don't inspect the exception status since may
short-circuits the operation. Use best-effort instead.
(ListMagickInfo): Don't inspect the current exception status so
that all the modules which did load successfully will be
represented.
(InitializeMagick): Invoke InitializeMagickModules().
- magick/log.c: (GetLogBlob): Eliminated function.
GetConfigureBlob() is safe to use now when configuring logging.
(LogToBlob): Simplified function. Only exists since FileToBlob()
may throw exceptions (which are logged, causing deadlock).
(ReadLogConfigureFile): Use GetConfigureBlob().
- magick/blob.c (GetConfigureBlob): Re-written to use the
MagickMap interface and to support the new 'lib' and 'share'
config directories. The directory
${prefix}/lib/GraphicsMagick-version/config is scanned before
${prefix}/share/GraphicsMagick-version/config.
(FileToBlob): Simplified implementation.
- config/Makefile.am: New makefile to install .mgk files.
- magick/magick_config.h.in: Added MagickLibConfigPath and
MagickShareConfigPath defines.
- configure.ac: Install configuration files (.mgk files) in
${prefix}/lib/GraphicsMagick-version/config and
${prefix}/share/GraphicsMagick-version/config. Architecture
independent files to under "share" while architecture dependnet
files go under "lib".
- Makefile.am: Added 'config' subdirectory to distribution. All
.mgk files are moved from 'coders' & 'magick' into this single
directory.
2003-10-21 Mike Chiarappa <mikechiarappa@libero.it>
- magick/studio.h: small modifications to achieve DLL
compilation of library with Borland C++ Builder.
- coders/ps3.c (ZLIBEncode2Image): Fixed bug. Compilation
fail when HasZLIB is undefined because parameters 5 and 6,
are undefined.
2003-10-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- libtool.m4: Updated libtool again to CVS latest version.
Libtool required some fixes for building DLLs under MinGW.
- magick/resource.c (InitializeMagickResources): Some code is
conditional based on HAVE_POPEN.
- magick/utility.c (SystemCommand): Improved conditional
compilation logic.
- magick/blob.c (OpenBlob): Code depending on popen() is
conditionally compiled based on HAVE_POPEN. Code depending on
pclose() is conditionally compiled based on HAVE_PCLOSE.
- configure.ac: Add test for _pclose(), pclose(), _popen(), and
popen().
- magick/locale.c (GetLocaleMessage): Add missing MagickExport.
(GetLocaleMessageFromID): Add missing MagickExport.
- VisualMagick/installer/inc/files-development.isx (Source):
Include all of the headers from the magick directory in the
development package. Including them individually is too error
prone.
2003-10-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/magick/magick_config.h.in: Added
PREFIX_MAGICK_SYMBOLS as a configuration option.
- magick/module.c (_CoderInfo): Added register_function and
unregister_function members to record the module's register and
unregister function addresses.
(OpenModule): Locate the module's register and unregister
functions and save their address to the module's CoderInfo record.
(UnloadModule): Invoke the module unregister function using the
address recorded by OpenModule().
(TagToFunctionName): If PREFIX_MAGICK_SYMBOLS is defined, then add
a "Gm" prefix to the register and unregister function names.
- libtool: Updated libtool files to the latest CVS version.
- configure.ac: Changed define name from MAGICK_SYMBOL_PREFIX to
PREFIX_MAGICK_SYMBOLS since support is not available for
specifying an arbitrary prefix.
2003-10-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Added --enable-symbol-prefix configure option
which prepends "Gm" to all GraphicsMagick library symbols using
the C pre-processor. In the future, this may change to support
specifying an arbitrary prefix, depending on experience.
- magick/studio.h: Include magick/symbols.h.
- magick/api.h: Include magick/symbols.h.
- magick/symbols.h: New header to support optionally remapping
library symbols. If MAGICK_SYMBOL_PREFIX is defined, then
library symbols are remapped.
2003-10-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/api.h: Removed inclusion of <magick/semaphore.h> since it
is an implementation header.
2003-10-13 Lars Skyum <lrs@stibo.dk>
- www/GraphicsMagick.html, www/animate.html, www/composite.html,
www/conjure.html, www/convert.html, www/display.html, www/gm.html,
www/identify.html, www/import.html, www/mogrify.html,
www/montage.html: added documentation for "-define" command line
option.
- doc/brief_options.imdoc, doc/options.imdoc: Added documentation
for "-define" command line option.
- doc/gmdocselect, doc/imdocselect: Changed "skipform" label in
sed scripts to just "skipf". Solaris sed had problems with the
long(?) "skipform" label.
2003-10-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- doc/composite.imdoc, doc/options.imdoc, doc/GraphicsMagick.imdoc:
Attempted to clarify the meaning of the compose arguments and how
composition works, as well as eliminating use of hard-coded values like
255.
- www/links.html: Added a link to Michael Still's article
"Graphics from the command line".
2003-10-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/*.c: Updated module descriptions so that they accurately
describe the module rather than saying "Read/Write GraphicsMagick
Image Format".
- coders/cineon.c: Fix source module description. Contrary to
opinion, ImageMagick did not invent the Cineon X image format so
description is now "Read/Write Cineon X Image Format."
- magick/magic.mgk: Added a CINEON entry for the Cineon X image
format.
- magick/static.c (RegisterStaticModules): Invoke
RegisterCINEONImage().
- coders/modules.mgk: Map "CIN" magick to CINEON module.
2003-10-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- locale/C.mgk: Added message for "UnrecognizedCommand".
- magick/command.c (MagickCommand): No error was reported when a
subcommand failed to be matched so 'gm foo' would silently return.
Now an error message is properly reported.
2003-10-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Makefile.am: Updated to Automake 1.7.8.
- various: Edits to eliminate minor issues detected by SGI C compiler.
- coders/ps3.c (WritePS3Image): Variable 'value was set but never
used so it is removed.
- magick/image.c (RGBTransformPacket): Removed inline request
since this function is too big to inline.
- magick/animate.c (XAnimateBackgroundImage): Fixed a GCC 3.X
"type pinning" warning.
- magick/display.c (XDisplayBackgroundImage): Fixed a GCC 3.X
"type pinning" warning.
- magick/render.c (GetPixelOpacity): Removed inline directive. No
one in their right mind could ever imagine this function inlining
successfully.
- magick/cache.c (IsNexusInCore): Adjusted so function inlines as
requested.
- coders/tiff.c (ReadTIFFImage): Improved logging information.
(WriteTIFFImage): Changed the way the bilevel/grayscale logic
works. Now bilevel images are treated similar to any other
grayscale image unless CCITT FAX3 or FAX4 compression is requested
(which selects the MINISWHITE photometric). The default is now to
write uncompressed bilevel images with MINISBLACK photometric.
- PerlMagick/t/composite.t: Use some reasonable error values.
- magick/image.c (GetImageDepth): Added special cases for
colormapped images and monochrome images in order to improve
performance.
2003-10-09 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- NEWS: added info about color scaling, sampling-factor, and
changed a reference to "-coder-options" to "-define".
2003-10-09 Lars Ruben Skyum <lars.skyum@stibo.com>
- VisualMagick/bin/modules.mgk: added EPS3 mapping to PS3 module.
- coders/ps3.c, coders/tiff.c, magick/command.c, magick/image.c,
magick/image.h, magick/utility.c: Changed -coder-options option to
-define. Also renamed functions {Add,Remove,Access}CoderOption(s)
to {Add,Remove,Access}Definition(s). Changed ps coder-specific
option ps:image=imagemask to just ps:imagemask.
2003-10-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/cineon.c: Imported and adapted Cineon image format coder
written by Kelly Bergougnoux <three3@users.sourceforge.net> with
assistance from John Cristy.
2003-10-08 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/jpeg.c: Extended -sampling-factor option to allow
user to supply full set of sampling factors. If the full
set is not supplied, omitted ones are 1x1 by default, similar
to the behavior of "cjpeg -sample".
- magick/command.c: Accept multiple pairs of sampling factors.
2003-10-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (WriteTIFFImage): Re-arranged logging for improved
output. Cleaned up evaluation of SAMPLESPERPIXEL and
BITSPERSAMPLE. Provided support for the TIFF coder options
tiff:samples-per-pixel and tiff:bits-per-sample for power users.
(ReadTIFFImage): Colormap generation for PHOTOMETRIC_MINISBLACK
and PHOTOMETRIC_MINISWHITE was inaccurate. Seems to be accurate
now.
- PerlMagick/t/reference/read/input.miff: Updated due to Glenn's
change to scale macros.
- PerlMagick/t/tiff/input_gray_12bit.tiff: Replaced 12 bit image
with a different one which is written by GraphicsMagick.
- coders/ps3.c (WritePS3Image): Use AccessCoderOption().
- magick/image.c (AccessCoderOption): Added a function to use for
accessing coder-specific options.
2003-10-08 Lars Ruben Skyum <lars.skyum@stibo.com>
- magick/attribute.c (TraceSVGClippingPath): optimized for speed
and precision in clipping mask generation by using lines to
connect Bezier curve anchor points where applicable.
2003-10-07 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- Revised ScaleColor5to8 and ScaleColor6to8 macros again, to
fill the low bits correctly.
2003-10-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/t/tiff/read.t: Added 16-color and 256 color
colormapped tests with a matte channel.
- PerlMagick/t/tiff/write.t: Added 16-color and 256 color
colormapped tests with a matte channel.
- coders/tiff.c (WriteTIFFImage): When using LZW compression,
apply the horizontal differencing predictor to RGB truecolor and
deep gray images since the TIFF spec says that LZW compression is
usually improved by using horizontal differencing with continuous
tone images.
Re-implemented grayscale and colormapped scanline preparation to
use the new bit-stream interface. This is a bit slower, but very
flexible, and the implementation is very compact. Writing of a
matte (transparency) channel is now believed to be correct for all
depths.
- magick/command.c (MogrifyImage): Only transform the colorspace
if it has been set (i.e. is not UndefinedColorspace).
2003-10-06 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/png.c (ReadOnePNGImage): PNG decoder would exit too
early when reading image.png[0].
2003-10-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/t/tiff/write.t: Added TIFF write tests for 4
bits-per-sample TIFF images, both with and without a transparency
channel.
- magick/image.c (DescribeImage): Added -verbose support for
displaying individual channel depths.
2003-10-06 Lars Ruben Skyum <lars.skyum@stibo.com>
- magick/image.c (SetImageInfo): cleaned up parsing of subimage
specification (image.psd[0]). It would fail sometimes due to
incorrect reuse of variables. It's a bit strange the code accepts
more range syntax-variations than can be stored in ImageInfo.
2003-10-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (ChannelImage): The OpacityChannel, MatteChannel,
and BlackChannel operations set the matte channel to opaque, so
set image->matte to False for those operations.
(RGBTransformImage): Add an assertion to prevent passing the
colorspace argument 'UndefinedColorspace'.
(TransformRGBImage): Add an assertion to prevent passing an image
with colorspace set to 'UndefinedColorspace'.
2003-10-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/log.c (LogToBlob): Since MagickSeek(file,0,SEEK_END) is
used to obtain the Blob size, MagickSeek(file,0,SEEK_SET) must be
used to restore the seek position. Thanks to John Cristy for
bringing this to our attention.
2003-10-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/bit_stream.h: Added a bit-stream writer function.
- PerlMagick/t/reference/read/input_tim.miff: Reference image
was defective.
2003-10-03 Lars Ruben Skyum <lars.skyum@stibo.com>
- magick/image.c, magick/image.h: Updated AddCoderOptions to
accept "flag" keys that have no values. They are placed in the
coder options map with an empty, zero length string value. Option
argument syntax is now: "key1[=[value1]],key2[=[value2]],..."
2003-10-03 Lars Ruben Skyum <lars.skyum@stibo.com>
- magick/command.c: Updated +coder-options option to not clear the
entire map of coder options, but accept a list of names to remove
from the map. Use option argument "*" to clear the entire map of
coder options.
- magick/image.c, magick/image.h: Added function
RemoveCoderOptions. Added cast of signed char to unsigned char and
int in calls to isspace and isprint.
- magick/utility.c: Added cast of signed char to unsigned char and
int in calls to isspace and isprint. Added special handling of
+coder-options option in ExpandFilenames function.
2003-10-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/t/reference/read/input_tim.miff: The TIM read results
changed somewhat due to Glenn's ScaleColor5to8 fix.
2003-10-01 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- Revised ScaleColor5to8 and ScaleColor6to8 macros to fill in
the low bytes.
- coders/bmp.c (ReadBMPImage): scaling of 8-8-8-8-bit images was
also slightly incorrect.
2003-09-30 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/bmp.c (ReadBMPImage): scaling of 5-5-5-bit and 5-6-5-bit
images was slightly incorrect.
2003-09-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (ReadTIFFImage): When using the generic bit-stream
marshaller to read colormapped/gray images, the slight performance
improvement from creating a special case for matte images did not
justify almost doubling the amount of code. Therefore, the two
loops are combined back into one.
2003-09-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (ReadTIFFImage): Fixed reading grayscale TIFFs
that have a transparency channel. Now uses a generic bit-stream
marshaller to allow reading any grayscale or colormapped TIFF with
any bits per sample in the range of 1 to 16.
- magick/bit_stream.h: Added a generic implementation for
marshalling from a bit-stream into a quantum. Still needs
re-writing for best performance.
- PerlMagick/t/tiff/read.t: Added a test case for reading 8-bit
grayscale TIFF with matte. Corrected grayscale 12-bit read
signatures. Added 16 color PseudoClass read test. Added 4-bit
grayscale read test.
2003-09-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (WriteTIFFImage): Add support for writing
DirectClass grayscale images at 4 bits per sample, including those
with an opacity channel. This allows writing smaller files
(half the size) when the image has 16 (or less) levels of gray.
Use "gm convert inimage.tiff -depth 4 outimage.tiff" to quickly
create grayscale TIFF file with 16 (or less) levels of
gray.
2003-09-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

ImageMagick 5.5.2, with a link to the ImageMagick site.
- Makefile.am: Add rules to generate www/AUTHORS.html.
- www/AUTHORS.html: New HTML file based on the AUTHORS file in the
source package. GraphicsMagick has many authors.
2003-09-25 William Radcliffe <billr@corbis.com>
- magick/image.c: Updated DescribeImage to cleanup EXIF data display
based on work by Cristy in ImageMagick.
2003-09-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (WriteTIFFImage): Add support for writing
colormapped TIFF images with 1, 2, & 4 bits per colormap index.
This allows writing smaller files.
2003-09-24 Lars Ruben Skyum <lars.skyum@stibo.com>
- coders/ps3.c: Now creates a correct %%BoundingBox for images
with resolution stored as pixels per centimeter. Renamed serialize
functions. Added comment headers where they were
missing. Reformatted code to be in alignment with GraphicsMagick
standard formatting.
- magick/map.c: Fixed semaphore double locking problem in
MagickMapCloneMap.
2003-09-23 Mike Chiarappa <mikechiarappa@libero.it>
- BCBMagick/readme.txt : Updated compilation instructions.
- BCBMagick/magick/libMagick.bpr : Updated project, now include map.c.
- BCBMagick/lcms/Projects/BCB6/lcms.bpr : Updated project, now include
cmscam02.c and cmsvirt.c.
Much thanks to Alex Dvoretsky for bringing this problem to my attention.
2003-09-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.h (Image): Moved private members to bottom of
structure.

- magick/cache.h (_CacheInfo): Changed 'Semaphore *' to 'void *'.
- magick/image.h (_Image): Changed 'Semaphore *' to 'void *'.
- magick/command.c: Updated each invokation of MagickMapAddEntry()
to add an exception argument.
- tests/maptest.c: Updated to pass an exception argument to
MagickMapAddEntry.
- magick/image.c (AddCoderOptions): Added exception argument
and some more error handling.

- magick/map.h: Changed all size parmeters from type 'unsigned
long' to 'size_t'.
- magick/map.c (MagickMapCopyBlob): Add new function to support

deallocating a Blob in MagickMap.
2003-09-23 Lars Ruben Skyum <lars.skyum@stibo.com>
- coders/ps3.c: Fixed handling the case when no -coder-options are
provided to the PS3 coder.
2003-09-22 Lars Ruben Skyum <lars.skyum@stibo.com>
- coders/ps3.c: Changed %%Creator version to use
MagickLibVersionText, increased precision in HiResBoundingBox,
added a coder specific option for rendering bilevel images with
the PS imagemask operator indstead of the image operator.
- magick/command.c: Added "-coder-options" command line argument
to all relevant command line utilities. Option argument to
-coder-options is a list of comma separated key-value pairs that
are saved in a MagickMap in ImageInfo for (de-)coders to use. See
PS3 coder for an example that checks for: -coder-options
"ps:image=imagemask"
- magick/image.c, magick/image.h: Added function AddCoderOptions().
- magick/map.c, magick/map.h: removed MS-DOS line terminators.
2003-09-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- tests/maptest.c (main): Test/demo program for key,value map API.
- magick/map.c, magick/map.h: Implementation of a key,value map
API for internal use.
2003-09-19 William Radcliffe <billr@corbis.com>
- lcms/include/icc34.h lcms.h: Added back the icc34.h header and
changes to make lcms compile on Win32" icc34.h lcms.h.
2003-09-19 Lars Ruben Skyum <lars.skyum@stibo.com>
- coders/ps3.c: Fixed warnings from Solaris compiler.
2003-09-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- locale/C.mgk: Eliminated the many "NotA" messages since they may
all be considered forms of "ImproperImageHeader". It is useful to
provide the origin of such messages in case the wrong coder has
been invoked, however, this is expensive to do via the message
database since it explodes the number of messages. The exception
logging can help here. Once the exception reports include the
reporting entity, it will be more clear when the software
misbehaves.
- magick/error.h (ThrowReaderException2): Remove since no longer
used.
(ThrowReaderException): Simplified implementation so that
ThrowException is not expanded twice.
- magick/error.h (ThrowReaderException3): Remove since never used.
- coders/xtrn.c (ReadXTRNImage): Use ThrowReaderException rather
than ThrowReaderException2.
- locale/C.mgk (MissingArgument) Updated to include %s so that the
description field appears earlier in the message.
- magick/error.c (DefaultErrorHandler): Added a hack to allow the
'reason' member to include a %s so that it may specify the
formating of the message. Care should be taken to not over-use
this hack.
2003-09-18 Lars Ruben Skyum <lars.skyum@stibo.com>
- coders/ps3.c: Major update of the PS3 coder. Now ascii85 encodes
all binary data. Many printer spoolers don't like the binary
data. The coder now creates much smaller files for bilevel, gray,
and colormapped images. Compression and image type is now
separated so they may be combined independently. Any alpha channel
is separated into a separate mask so it's possible to mask
bilevel, gray, colormapped, rgb, and CKYK images. You may also
mask a JPEG compressed PS file for instance. Clipping masks
created from a photoshop clipping path with -clip option is
converted to a corresponding postscript clipping path. New
functions need comment headers.
- magick/attribute.c: Added TracePSClippingPath for creating a
postscript clipping path from a photoshop clipping path.
- magick/compress.c, magick/compress.h: Added write-hook based
interface to compression functions. Required for ascii encoding
compressed, binary data. The interface between blob write
functions, compression functions, and encoding functions could
benefit from more of this work.
- magick/image.c: ClipPathImage now stores the name of the
clipping path in the mask image filename so that it is remembered
and may be used for creating a postscript clipping path for
postscript output.
- coders/modules.mgk: Added EPS3 mapping to module PS3.
2003-09-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c: Coalesced various "Missing" error reports into
one "MissingArgument" error report in order to reduce the number
of messages to be maintained.
- locale/C.mgk: Removed almost all "Missing" messages.
- magick/gm_messages.mc: Added Microsoft message compiler source
file to CVS until which time it may be generated automatically
during the build.
2003-09-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- locale/Makefile: Added ability to generate gm_messages.mc
(for Windows message compiler) as well as adding 'clean' and
'install' targets.
- magick/delegate.h: Visual Studio .NET 2003 doesn't like
the chaining of GhostscriptVector members which share a
common return type. Splitting the definitions solves this
problem.
2003-09-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/deprecate.h (MagickSignedType): Compatibility definition
to handle ImageMagick API change.
(MagickUnsignedType): Compatibility definition to handle
ImageMagick API change. The new names are just as useless as the
old names, but at least they are shorter.
- magick/command.c: Linux's sscanf has the terrible bug that it
improperly handles pulling out the first floating value from the
string "0x1". Instead of retrieving the value 0 and returning 1,
it returns 0, probably because it rejects the string as a hex
constant. As a result, all options which used sscanf to validate
this input are now converted to use IsGeometry().
2003-09-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- ltdl/ltdl.c: Update to libltdl current as of today.
- ltmain.sh: Update to libtool current as of today.
- configure.ac: For HPUX C++ compiler, add -AA to CXXFLAGS rather
than CXX.
2003-09-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Decided that the standards conformance
defines create more problems than they solve so they are
removed.
Move the large-file tests to before the libtool configuration
since the libtool configuration was causing stdlib.h to be
included prior to the large file defines, and this causes
header failure with C++ under AIX.
- www/api/types.html: Update description of MonitorHandler.
2003-09-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Set CXX to PTHREAD_CXX if necessary (and warn).
- acinclude.m4 (ACX_PTHREAD): Add check to see if xlC_r should be
used for AIX.
2003-09-10 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- magick/render.c: Fixed handling of arc primitive (see IM-5.5.8).
2003-09-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/log.h: It seems that test programs are using
GetMagickModule so make it visible by default.
- configure.ac: Use GM_FUNC_MMAP_FILEIO macro to test mmap.
- acinclude.m4 (GM_FUNC_MMAP_FILEIO): New macro to test mmap's
capability to do coherent file I/O. The AC_FUNC_MMAP macro
was not testing the mmap features that GraphicsMagick uses, and
was failing on a number of systems.
- magick/blob.c (BlobMapModeToString): Only include this static
function if HAVE_MMAP is defined.
- coders/locale.c (WriteLOCALEImage): Fix FormatString argument
type inconsistencies.
- wand/magick_compat.h: Change MagickExport to WandExport.
- coders/jpeg.c, coders/locale.c, coders/meta.c, coders/miff.c,
coders/palm.c, coders/pict.c, coders/svg.c, coders/tiff.c,
coders/topol.c, magick/cache.c, magick/display.c, magick/image.c,
magick/widget.c: Removed unused values, changed storage types, or
added explicit casts, in order to reduce the number of "REMARK"s
when using the SGI IRIX compiler.
- magick/render.c (DrawClipPath): Fix memory leak of
clone_info->clip_path. Problem reported by Vladimir
<lvm@integrum.ru>.
(DestroyDrawInfo): Remove unnecessary checks for non-null prior to
invoking MagickFreeMemory. MagickFreeMemory already checks for
non-null.
- magick/log.h (GetCurrentFunction): Apparently Visual C++ 6.0
does not support __FUNCTION__. Problem reported by Vladimir
<lvm@integrum.ru>.
- wand/magick_compat.c: All functions in magick_compat.c must use
WandExport rather than MagickExport. Fix recommended by Vladimir
<lvm@integrum.ru>.
- magick/constitute.c (PushImagePixels): number_pixels was always
cast to a long during use, so change to store value in a long
instead.
(PopImagePixels): number_pixels was always
cast to a long during use, so change to store value in a long
instead.
2003-09-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/psd.c: Eliminated warning regarding unused initialized
variable.
- magick/log.c: Eliminate type warnings regarding enum assignment.
- coders/locale.c (WriteLOCALEImage): Use UndefinedException
rather than 0 in severity_list terminating entry in order to avoid
a type conversion warning.
- magick/image.c (SetImageChannelDepth): Depth parameter was being
returned rather than status. Oops!
- magick/effect.c (BlurScanline): Due to automatic casting
conventions, computation was being done (at least with SGI
compiler) as type 'unsigned long' rather than 'long' as it should
have been.
- coders/jpeg.c, coders/meta.c, coders/miff.c, coders/msl.c,
coders/palm.c, coders/pcd.c, coders/psd.c, coders/svg.c,
coders/tiff.c, coders/xcf.c, magick/render.c, : Quench many SGI
compiler warnings regarding variables which are initialized but
never used.
- magick/xwindow.h: Undef gravity defines so that enumerated type
is used instead.
2003-09-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/log.c (LogMagickEvent): Windows system logging
functionality is not currently ported to work with Cygwin so
disable when compiling under Cygwin.
- magick/log.c (Win32EventlogOutput): Remove spurious comma in enum.
- wand/drawing_wand.h: Remove junk comment marker that I forgot to
remove.
- magick/studio.h: Provide prototypes for strlcpy and vsnprintf if
the system doesn't provide them in the requested compilation
environment.
- configure.ac: Add necessary standards compilance definitions to
magick_config.h.
Check for strlcpy and vsnprintf prototypes.
- Makefile.am (DOCDIRS): www/api/types does not exist anymore.
2003-09-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Move multithread tests prior to libtool
configuration in case value of CC is changed. Otherwise libtool
gets confused and refuses to run.
- acinclude.m4 (ACX_PTHREAD): If using AIX CC 'xlc' use 'xlc_r'
for multithread compiler.
- coders/jpeg.c: Undef HAVE_STDLIB_H before including the
jpeg headers or else we get an already defined error/warning.
2003-09-04 Mike Chiarappa <mikechiarappa@libero.it>
- BCBMagick : Updated whole directory tree to achieve correct
compilation with Borland C++ Buider 6.0.
2003-09-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (ClipPathImage): Remove MS-DOS line terminations
(actually, extra carriage returns) which somehow crept into
ClipPathImage.
- locale/C.mgk: Added message for "PNG library is too old".
2003-09-04 Lars Ruben Skyum <lars.skyum@stibo.com>
- magick/transform.c (ProfileImage): Bugfix: conditional
compilation based on LCMS being present or not now works as
expected. An exception is thrown if LCMS is not present and
profile conversion is used.
2003-09-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/txt.c (ReadTXTImage): Fix strlen() pointer type warning.
- magick/image.c (TextureImage): Fixed return with no value warning.
- magick/color.c (GetColorInfoArray): Decided that the const
return value was a bad idea. Therefore, the return type has been
made non-const.
- magick/magick.c (GetMagickInfoArray): Decided that the const
return value was a bad idea. Therefore, the return type has been
made non-const.
- tests/constitute.c, tests/rwblob.c, tests/rwfile.c : Define
MAGICK_IMPLEMENTATION since these test programs using some internal
extensions.
- configure.ac: Test C++ compiler for __func__ support.
- magick/log.h: Added GetCurrentFunction() macro to handle
__func__ support determination. Re-wrote GetMagickModule() macro
to use GetCurrentFunction(). Changes should allow compilation of
Magick++ when the C compiler supports __func__ but the C++
compiler does not.
- configure.ac: Changed from using HAS___func__ define to
HAS_C__func__ since this feature may be language sensitive.
- locale/C.mgk: Added missing JNGCompressionNotSupported message.
2003-09-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/attribute.c (Generate8BIMAttribute): Fix sscanf argument
type mis-match.
- coders/ps3.c (ZLIBEncodeImage): Fix mis-classified
ZipLibraryIsNotAvailable error report.
- coders/url.c (RegisterURLImage): Only register URL format
support if libxml2 is available.
- coders/msl.c (RegisterMSLImage): Only register MSL format
support if libxml2 is available.
2003-09-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/histogram.c (WriteHISTOGRAMImage): Remove a useless loop.
- coders/wpg.c: Applied patch from Fojtik Jaroslav to support
reading WPGs which use the EXT token.
2003-08-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/color.c (HistogramToFile): Renamed static method
'Histogram' to 'HistogramToFile' to make it more clear what this
function does.
(GetColorHistogram): Added new function to support retrieving a
color histogram of the image. A color histogram contains a count
of how many times each color occurs in the image.
- magick/image.c (GetImageChannelDepth): Return an 'unsigned int'
rather than 'long'.
2003-08-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/Magick.xs: Add support for CopyCyan, CopyMagenta,
CopyYellow, and CopyBlack, composition operators.
- magick/composite.c (CompositeImage): Added support for
CopyCyanCompositeOp, CopyMagentaCompositeOp,
CopyYellowCompositeOp, and CopyBlackCompositeOp, composition
operators.
2003-08-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- wand/*: Updated to current ImageMagick Wand API (minus a few
unimplemented functions).
- magick/image.c (TextureImage): Add status return because Wand API
wants it. Inherit is_grayscale status from texture image.
- magick/fx.c (SolarizeImage): Add status return because Wand API
wants it.
- magick/resource.c (SetMagickResourceLimit): Add status return
because Wand API wants it.
- magick/draw.c (DrawPeekGraphicContext): Now returns a
copy of the current DrawInfo context rather than returning
a pointer into the context stack. The user must destroy
this copy using DestroyDrawInfo() once it is no longer
needed.
2003-08-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/filters/LIBRARY.txt: This file is necessary to
incorporate analyze.c into the static build. Without it the
build fails.
2003-08-23 Lars Ruben Skyum <lars.skyum@stibo.com>
- magick/transform.c: ProfileImage updated to handle alpha
channels and grayscale images. Also optimized color profiling of
color mapped images and fixed a few bugs in profiling of CMYK
images.
- magic/locale_c.h: added MagickExport to prototype declaration of
GetLocaleMessageFromID in WriteLOCALEImage again. Please update
your locale coder.
2003-08-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/wpg.c: Applied patch from Fojtik Jaroslav to use the
GetMagicInfo() function to obtain the format of embedded images,
and to provide a default WPG palette if the WPG file does not
supply a palette.
2003-08-22 William Radcliffe <billr@corbis.com>
- magick\gm_messages.bin locale_c.h transform.c: Fixed missing
message problem and added support for new lcms error handler.
2003-08-21 Lars Ruben Skyum <lars.skyum@stibo.com>
- magick/attribute.c, magick/image.c, magick/command.c: Added
"clippath" option for clipping named Photoshop clipping paths,
increased precision in clipping path knots, added comments, and
fixed a few bugs resulting from moving TraceClippingPath function
from ImageMagick to GraphicsMagick. Still need to update some of
the documentation.
- magick/locale_c.h, magick/studio.h: added MagickExport to
declaration of GetLocaleMessageFromID and moved include of
magick/locale_c.h after declaration of MagickExport. This fixes a
link error in dynamic, DLL version.
- coders/locale.h: added MagickExport to prototype declaration of
GetLocaleMessageFromID in WriteLOCALEImage.
2003-08-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/t/subroutines.pl (testRead): Ignore useless TIFF
warning so that 12-bit TIFF test passes.
- magick/constitute.c (ReadImage): Ensure that the reported image
magic string is that of the user-specified input file rather than
a temporary file prepared by an external delegate program.
- magick/command.c (ImportImageCommand): Since
DestroyExceptionInfo() now sets the destroyed exception signature
to an invalid value, GetExceptionInfo(exception) must be invoked
when the intention is to simply purge the exception. This fix
resolves an abort when executing 'gm import'.
2003-08-18 William Radcliffe <billr@corbis.com>
- magick\gm_messages.bin locale_c.h transform.c: Updates that
add latest enhancments by Lars to color management code in
ProfileImage.
2003-08-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/wpg.c: Incorporated patch from Fojtik Jaroslav to support
rendering embedded WMFs.
2003-08-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (SetImageChannelDepth): New function to transform
the specified channel so it fits the specified modulus depth.
- magick/blob.c (BlobToImage): Skip calling SetImageInfo() if
magick is already set.
2003-08-18 William Radcliffe <billr@corbis.com>
- PerlMagick/Magick.xs: Some fixes to get PerlMagick compiling
again due to new ID based error macros.
2003-08-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/error.h (enum): Remove spurious comma.
2003-08-17 William Radcliffe <billr@corbis.com>
- coders\png.c: Had to modify a few exception calls to work with
newest macros.
2003-08-17 William Radcliffe <billr@corbis.com>
- coders\locale.c magick/error.h locale.c locale_c.h studio.h:
The LOCALEH header file generator now adds an MGK_ prefiix to
all the ID defines as part of a fix to support the new error
and exception macros cross platform.
2003-08-16 William Radcliffe <billr@corbis.com>
- wand\magick_wand.c pixel_wand.c: The wand api code was totally
left out of the large macro conversion below as an oversight.

xwindow.c : Changes to support ID based message access and checking
all message usages. The main thing that was done was to remove all
the quotes around the "tags" used to lookup messages defined in
the locale\C.XML file. Macros were added to error.h to allow the
code to be compiled for either string based access or binary ID
based access. Using binary ID's will cause the code to fail to
compile if a message does not exist in C.XML, since no ID will be
created for a missing message. This change then allowed us to
easily track down all the messages that were "missing" or not
being accessed properly. The problems were massive and took many
days to resolve. I have left the code compiling in ID mode to keep
things in sync going forward and also because it makes message
lookup instantaneous. An ID is just an index into and array of
char *'s. There is still a lot of cleanup work remaining, but this
is a very good start.
2003-08-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/error.c (GetLocaleExceptionMessage): Add check to avoid
duplicating severity prefix.
- magick/log.c (LogMagickEvent): Incorporated fix from Bill
Radcliffe to enable logging control flags to work properly again.
- NEWS: Updated news.
- magick/blob.c (OpenBlob): Rewind file descriptor so that first
read is at zero offset. This fixes reading GIFs via a
user-provided file handle.
2003-08-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (GetImageDepth): Extend so that the actual
minimum depth required to represent the image is
returned. Previously only the values 8, 16, and 32 were
returned. This means that a value of one is returned for a
monochrome image. Also fixed a bug in that the pixels were
incremented while the depth was incremented, resulting in the
first image pixels not being properly evaluated for depth.
(SetImageDepth): Extend to support converting the image to
arbitrary modulus depths.
(GetImageChannelDepth): New function to obtain the modulus depth
for a specified image channel.
2003-08-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/draw.c (MvgAutoWrapPrintf): StreamError reported when
DrawError was intended.
- coders/logo.c (ReadLOGOImage): Report FileOpenError rather than
BlobError if requested image does not exist.
2003-08-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/cache.c (PersistCache): If HAVE_SYSCONF and _SC_PAGE_SIZE
are defined, then assume that sysconf works and don't use legacy
getpagesize() function.
- magick/studio.h (_XOPEN_SOURCE): Should be defined as 600 in
order to match _POSIX_C_SOURCE=200112L according to the Single
UNIX Specification v3. This is necessary for the vsnprintf
prototype to be visible.
- magick/attribute.c (ReadByte): Fix compilation warnings due to
casting 'unsigned char *' to 'char *' by changing function
definition to accept 'unsigned char *' instead.
- magick/error.h (UndefinedException): UndefinedException should
be ExceptionType, not ExceptionBaseType.
- magick/magick.c (IsValidFilesystemPath): Eliminate warning about
unused function when UseInstalledMagick is defined.
- magick/error.c (ThrowLoggedException): Fix improper parameters
passed to LogMagickEvent() when reason is not available.
003-08-07 William Radcliffe <billr@corbis.com>
- magick/log.c, log.h: Added ability to log by either severity
or by category of event. Made the defualt on windows to log all
fatal errors, errors, and warnings to the event log. This will
include anything generated by exceptions currently, but not any
normal "informational" logging.
2003-08-07 William Radcliffe <billr@corbis.com>
- magick/log.c, log.h: Translation of event codes to mask vals
was not working. Code was left out of last update. It is now in.
2003-08-07 William Radcliffe <billr@corbis.com>
- magick/error.c: Protect against NULL string passed into the
message lookup function.
2003-08-07 William Radcliffe <billr@corbis.com>
- magick/locale.c: Switched use of IsAccessible to nonloggging
version to prevent recursive problems.
2003-08-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/Makefile.am (noinst_HEADERS): Distribute locale_c.h.
- locale/Makefile: Output locale_c.h.
- utilities/gm.c (main): Fix typo in Unix InitializeMagick
invocation.

conditional define to HAVE_PTHREAD.
- magick/Makefile.am (noinst_HEADERS): Include spinlock.h in
distribution.
2003-08-06 William Radcliffe <billr@corbis.com>
- contrib\win32\ATL7\ImageMagickObject/ImageMagickObject.cpp,
ImageMagickObject_.h, ImageMagickObject.def, ImageMagickObject.rc
gm.rc: Changes to get things compiling again since all windows
specific logging support has been eliminated. The special build
script BuildImageMagickObject.cmd now compiles the message file
for resource based messages. The result is in gm_messages.bin.
The script also generates a special version of gm.exe that uses
the COM dll as a regular DLL and links to it. This is the long
desired Moby DLL build idea.
- magick/error.c, magick/error.h, magick/log.c, magick/log.h:
Upgrade of logging system to take over previous special logging
code for windows in nt_base.c. The new logic provides logging
of events to the debug api and the windows event log and also
provides a generic text file logging method.
- magick/gm_messages.bin, magick/ImageMagick.rc: New compiled
message file based on data in locale\C.mgk. RC file modified
to include this as a resource.
- magick/locale.c, magick/locale_c.h: locale_c.h is generated by
the LOCALEH format of the locale coder. The logic in locale.c
uses the tables in the header lookup messages. On windows, all
the messages are stored as resources, while on UNIX they remain
in a string table.
- locale/C.mgk: Removed duplicate messages and added some new
default messages that help to create a complete set of severity
strings.
- magick/command.c, magick/magick.c: Get rid compiler warnings.
2003-08-05 William Radcliffe <billr@corbis.com>
- magick/command.c, magick/gm.c: Application level changes to
implement the client name - filename changes. The client name
can now be anything that the application wants and has nothing
to do with the saved filename of the application.
- magick/nt_base.c, magick/nt_base.h, magick/magick.c: Ripped
out old nt specific debugging and logging logic. Moving to the
standard logging. New and major revisions to InitializeMagick
to make the code more maintainable, reliable, and reaable. It
should be functionally identical, but implements the new split
client name and filename methododology.
- magick/utility.c, magick/utility.h: Added a couple of new
routines to support splitting the overloaded use of the client
name and client filename.
- coders/xtrn.c: Minor code cleanup
2003-08-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Copyright.txt: Added missing copyright notice which is required
due to copying the rlecomp manual page into ImageMagick.
- doc/config_files.imdoc: Started documentation for configuration
files.
- magick/xwindow.c (XSignalHandler): Ensure that segment_info is
non-null before attempting to use it. Much thanks to John Cristy
for bringing this problem to our attention.
2003-08-05 William Radcliffe <billr@corbis.com>
- coders/locale.c: Added several new formats to this coder to
generate windows message resource format messages and also to
generates a new header file format that will support a table based
version of the other magick/locale.c.
- coders/xtrn.c: Minor code cleanup
2003-08-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Only configure C and C++ libtool tags.
- PerlMagick/t/reference/composite/*.miff: Added some composition
test reference images. These reference images will serve as
placeholders until better composition tests can be figured out.
It is not clear from the documentation what some of the
composition operators are supposed to do.
2003-08-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- README.txt: Add documentation regarding using TRIO.
- configure.ac: Test for TRIO library if vsnprintf is not

(SetLogEventMask): Move event parsing to
ParseEvents funtion.
- magick/utility.c (GetGeometry): Validate that the geometry
string only contains valid characters.
- PerlMagick/t/subroutines.pl (testMontage): It seems that passing
an empty set of options to the SetImage method corrupts the image
options (surely a PerlMagick bug), so don't invoke SetImage unless
there are options to set.
2003-06-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c (VersionCommand): Add build information to
version output.
- configure.ac: Save configure/build parameters for later use in
version output.
2003-06-04 William Radcliffe <billr@corbis.com>
- coders/meta.c: Added some casts to make things compile better.
2003-06-03 William Radcliffe <billr@corbis.com>
- coders/meta.c: Was broken due to editing mistakes as well
as inherent incompatability with MagickReallocMemory macro.
2003-06-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/xpm.c (RegisterXPMImage): Module registration for PICON
should have been XPM. Thanks to John Cristy for noticing this
bug.
- coders/psd.c (ReadPSDImage): Applied John Cristy's patch to fix
a index calculation bug which is evident when QuantumDepth>8.

to MagickCommand to maintain backward compatability with previous
versions of GM.
- magick/command.c: Added flag to tell MagickCommand whether GM is
expected to process metadata requests. The COM object *always* does.
- magick/transform.c: Added error handling, memory leak avoidance
and performanc enhancment.
2003-06-01 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- NEWS: Added Bug Fixes item with info about the JNG encoder fix.
2003-06-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- NEWS: Listed significant changes (thus far) in version 1.1.
- version.sh: Updated LIBRARY_CURRENT and LIBRARY_REVISION since
some command.c interfaces have changed, and a new interface has
been added. The only user of these interfaces should be 'gm' but
it always pays to be careful.

stupendously significant accomplishment.
- magick/command.c: Added a '-list modulemap' option. Added plural
forms of other list options for people who are are not limited to
the singular. Also '-list font' and '-list fonts' now work for
people who think in terms of fonts rather than type.
2003-05-30 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- MNG encoder failed to set the JNG bit in the simplicity profile.
- MNG encoder failed to write FRAM chunks when all images were JNG.

CorruptImage rather than CorruptPDBImageFile.
2003-05-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/bin/modules.mgk: Add mapping from SVGZ to SVG.
- coders/modules.mgk: Add mapping from SVGZ to SVG.
- coders/svg.c (RegisterSVGImage): Add registration for SVGZ
format.
- PerlMagick/t/zlib/read.t: Added test to check reading a file
with .gz extension. The blob portion of the test currently fails.
- coders/wpg.c (ReadWPGImage): Fix reading WPGs with embedded
Postscript. Ensure that scene numbers are sane. Bugs remain.
- magick/blob.c (OpenBlob): Recognize the .svgz extension as a
gzipped format. Not required in order to read .svgz files since
the blob file magic detects gzip files.
- magick/command.c (MontageImageCommand): Wrong exception
macro was being invoked. Steps have been taken to ensure that
this doesn't happen again.
(ImportUsage): Fix spelling of 'type'.
- magick/magick.c (DestroyMagick): Decided that initialization
state should be tracked via an enum so that DestroyMagick will
take effect even if InitializeMagick has never been called.
2003-05-27 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/png.c: png.c would dump core when writing a grayscale
image in png24 or png32 format.
2003-05-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/ept.c (WriteEPTImage): Fixed writing EPT preview image and

then negate the `K' channel as well.
- PerlMagick/Magick.xs: Fix spelling of 'elevation' argument to
Shade method.
- magick/image.h (ImageInfo): Added more documenting comments.
- magick/image.c (CloneImage): Don't clone huffman ascii85
encoding support structure since it is not useful outside of the
current image context. Cloning a structure via pointer assignment
causes a memory leak.
2003-05-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/shear.c: Incorporate math tweaks obtained from
ImageMagick which are purported to improve accuracy when rotating
and shearing using small angles. Also avoid unneccessarily
transforming CMYK images into RGB images.
- magick/paint.c (ColorFloodfillImage): Fix hang while
floodfilling using a pattern image with color similar to the
border color.
- coders/modules.mgk: Add missing mappings for PNG8,
PNG24, and PNG32.
- VisualMagick/bin/modules.mgk: Add missing mappings for PNG8,
PNG24, and PNG32.
2003-05-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/log.c (GetLogBlob): Return an error if log.mgk can not
be accessed.
- locale/C.mgk: Added UnableToAccessLogFile.
- magick/blob.c (GetConfigureBlob): Only return result of
NTResourceToBlob if it is non-NULL.

while updating the code to use the memory allocation macros.
2003-05-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/GraphicsMagick-config.in (usage): Added example
usage to the help output.
- magick/magick.c (InitializeMagick): Added a static flag to
ensure that the Magick library is initialized only one time.
(DestroyMagick): Ensure that Magick library resources are only
destroyed if it has previously been initialized.
- magick/nt_base.c (DllMain): Fix contributed by Achim Domma. For
a DLL build, update PATH during Magick DLL initialization to
include the directory where the Magick core DLL resides. This
allows the loadable modules to find the core DLLs, even if the
core DLLs are not already in the PATH.
- magick/image.c (TextureImage): Incorporate new implementation
authored by John Cristy of ImageMagick Studio. This
implementation is a full 7X (run-time) or 14X (user-time) faster
than the original ImageMagick implementation, and is about 2X
faster than the speeded-up version I commited on the 19th.
2003-05-20 William Radcliffe <billr@corbis.com>
- VisualMagick\configure : Fixed bug with add on (plug-ins) not
building automatically in DLL mode.

- VisualMagick/bin/modules.mgk: Map "PATTERN" to "LOGO".
- coders/modules.mgk: Map "PATTERN" to "LOGO".
- coders/logo.c (ReadLOGOImage): Add "PATTERN" tiling support in
order to be compatible with ImageMagick.
- magick/image.c (SetImageInfo): Map "MAGICK" magick to "IMAGE" in
order to be compatible with ImageMagick.
2003-05-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

MagickReallocMemory. Eliminated warnings when compiling with
GCC 3.3 using -Wall.
- images: The logo image was determined to have a copyright
problem so replace with blank image until a replacement is
available.
2003-05-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/magick/magick_config.h.in (HAVE_SYS_TYPES_H):
Moved this define back from nt_base.h since removing it was
causing some problems for Magick++.
2003-05-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c: (SetMagickInfo): Don't mask failure to
read magic.mgk.

an existing exception.
- magick/nt_base.h: Imported some obscure defines from
magick\magick_config.h.
- VisualMagick/magick/magick_config.h.in: Improved description
text and formatting. Moved some obscure defines to
magick/nt_base.h.

code, and improve coding style.
- coders/logo.c, Copyright.txt, www/Copyright.html: Acknowledge
and respect the XFig copyright.
- VisualMagick/installer/inc/files-documentation.isx: QuickStart.txt
is no longer distributed so it is removed.
2003-05-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.h (RoundToQuantum): New macro to round positive
double to Quantum.
- magick/xwindow.c, magick/xwindow.h, magick/studio.h: Use FreeBSD
portability fixes from FreeBSD ports collection.
- configure.ac: Test for <machine/param.h> as used by some *BSD systems.
- QuickStart.txt, www/QuickStart.html: Don't distribute QuickStart.txt or
www/QuickStart.html since the content doesn't currently apply to
GraphicsMagick.
2003-05-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- README.txt: Added text regarding where to obtain dcraw, a simple
but useful decoder for the proprietary raw file formats produced
by digital cameras (58 supported cameras!).

as well as VisualMagick builds. Includes changes for the
meta.c code.
2003-05-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- www/formats.html: Documented embedded gray intensity images.
- coders/logo.c: Added the embedded dithered gray intensity images
gray0, gray5, ..., through gray100 to support bilevel filling and
painting with an intensity resolution of 5%.
- www/formats.html: Added description of images available via
"IMAGE:" format tag, as well as providing a tiled preview.
- coders/logo.c: Renamed "transparent" image to "checkerboard"
since it is a better description. Added a set of tiny bilevel
images (accessed via IMAGE:) for use when tiling, filling, or for
use as a texture image. The complete set of image names available
via the IMAGE: coder are now BRICKS, CIRCLES, CROSSHATCH,
CROSSHATCH30, CROSSHATCH45, FISHSCALES, GRANITE, HEXAGONS,
HORIZONTAL, HORIZONTALSAW, HS_BDIAGONAL, HS_CROSS, HS_DIAGCROSS,
HS_FDIAGONAL, HS_HORIZONTAL, HS_VERTICAL, LEFT30, LEFT45,
LEFTSHINGLE, LOGO, NETSCAPE, OCTAGONS, RIGHT30, RIGHT45,
RIGHTSHINGLE, ROSE, SMALLFISHSCALES, CHECKERBOARD, VERTICAL,
VERTICALBRICKS, VERTICALLEFTSHINGLE, VERTICALRIGHTSHINGLE, &
VERTICALSAW. The HS_* variants are similar to the standard
pattern images provided with the Windows GDI.
- coders/msl.c (MSLStartElement): Don't reset gravity if the user
provides an x,y coordinate. Passing coodinates was loosing the
gravity setting.
2003-05-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/modules.mgk: Support the IMAGE: format via the LOGO
module.
- win2k/IMDisplay/IMDisplayView.cpp (DoDisplayImage):
Transparent tile is created by reading "tile:image:transparent".
- coders/logo.c (ReadLOGOImage): Add IMAGE: format to front for
embedded images so that adding new images doesn't proliferate coder
registrations. Legacy logo magick names (GRANITE, LOGO, NETSCAPE,
and ROSE) are still supported, but they are also available in the
IMAGE file space (e.g. IMAGE:ROSE).
2003-05-09 William Radcliffe <billr@corbis.com>
- VisualMagick\configure : Further refinements that support both
the new "big" library and the normal dynamic DLL buidling styles.
2003-05-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/logo.c (ReadLOGOImage): Added a "TRANSPARENT" pattern
image which can be tiled to form the background of transparent
images.
- win32/IMDisplay/IMDisplayView.cpp: When displaying images which
include an opacity channel, use a checker-board pattern as the
image background so non-opaque pixels become evident.
2003-05-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/meta.c : Add or fix commenting of DebugString so that
module does not require Windows.
- lcms: Updated to release 1.10.
2003-05-07 William Radcliffe <billr@corbis.com>
- VisualMagick\bin : Brought the MGK files back into sync with
the rest of the package and added types for meta.c.
- VisualMagick\bin\win32\ATL : removed config files in order to
prevent very old ATL project from being picked up in the config
2003-05-06 William Radcliffe <billr@corbis.com>
- VisualMagick\lcms\LIBRARY.txt : a define to prevent popup message
box behaviour.
- VisualMagick\configure\ : New feature - -t consolidates all the
coders into on library for the static build in order to make the
build process tolerable.
- coders\xtrn.c : new support for BSTR - wdie character data
- coders\svg.c : put back logic that allows the -size parameter to
control the pixel dimensions of the output image.
- coders\meta.c : added support for wide character parsing of iptc
and 8BIM formats.
2003-05-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- version.sh : Update to reflect development status.
2003-05-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- GraphicsMagick 1.0 Released.
- version.sh (LIBRARY_REVISION): Updated for the 1.0 release.
- magick/studio.h: Add fix to avoid problems caused by zlib
under AIX.
- magick/cache.h: Parameterized prototypes to make them easier
to follow.
- filters/analyze.c: Replace C++ comments with C comments.
- magick/command.c: For the composite, convert, identify, mogrify,
and montage commands, make sure a usage error is returned if a
usage message is printed. This is useful for ImageMagickObject
users who won't see the usage message if stdio is not supported.
- locale/C.mgk: Added "UsageError" error. Added missing closure
to <Corrupt> tag which caused most/many message lookups to fail.
- magick/nt_base.h: Fixed a compile problem caused by masking
internals in delegate.h
- magick/ImageMagick.rc: Added missing .mgk files.
2003-05-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/nt_base.c (lt_dlerror): Defining lt_dlerror to be
NTGetLastError was not a correct implementation since the
interface is defined to return a const pointer to a string, but
NTGetLastError returns an allocated string, causing a memory leak
if NTGetLastError is used in the place of lt_dlerror. A new
lt_dlerror function is added to fix this.
(lt_dlsetsearchpath): lt_dlsetsearchpath should return an int
and accept a const char *.
(lt_dlsym): lt_dlsym is supposed to take a const char *.
- magick/nt_base.h: lt_dlclose should return an 'int'.
- magick/nt_base.c (lt_dlclose): Return status from lt_dlclose.
- magick/module.c (lt_dlclose): lt_dlclose is supposed to return
an 'int', not 'void'. A return value of zero indicates success.
- VisualMagick/tests/run_constitute.bat: Add batch script to
run constitute tests.
- magick/module.c: Added a ltdl_initialized static flag to track
if libltdl has been initialized by lt_dlinit().
(TagToFunctionName): Use a stack buffer for the string rather than
allocating heap data.
(UnregisterModule): Report errors via exception info as the
interface suggests.
(UnloadModule): Report errors via exception info as the interface
suggests.
(DestroyModuleInfo): Only invoke lt_dlexit() if lt_dlinit() has
previously been invoked.
- locale/C.mgk: Added FailedToCloseModule module error.
- magick/module.c (UnloadModule): Report exception via exception
parameter rather than simply printing out an error message and
exiting.
- magick/Makefile.am (noinst_HEADERS): integral_types.h had to be
listed *somewhere* in order to make it into the distribution.
- Magick++/lib/Magick++/Image.h: InitializeMagick must be DLL
exported.
2003-05-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Makefile.am (magick-version): Perform version.isx substitutions
via Makefile.am rather than configure.
- magick/magick_config_api.h.in: Added template header for
the installed magick_config.h.
- magick/magick.c (InitializeMagick): Improved the signal handling
and registration method. Signal handlers are only registered for a
signal if the current signal handling disposition for that signal
is set to the default (SIG_DFL). When a signal is caught,
DestroyMagick is invoked, the handling for the signal is set back
to SIG_DFL, and then the signal is re-raised to trigger the
default handler for that signal. This causes the process to behave
as closely to the default as possible (e.g. generating a core
file) while ensuring that DestroyMagick is executed. This also
ensures that signal handlers registered by API users are not
overridden by invoking InitializeMagick.
- configure.ac: Added tests for sigemptyset and
sigaction.
Add a check for the return type of signal handlers.
Test for the 'raise' function.
- www/formats.html: Add an entry for CUR, Microsoft
Cursor Icon format.
2003-05-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/semaphore.c (struct SemaphoreInfo): Added
`locked' and `thread_id' members. These are used to record
if the semaphore is locked, and to validate the thread
ID of the unlocker.
- www/links.html: Added link to Nathan Day's MagickDocs
"ImageMagick and GraphicsMagick documentation project"
site.
Added a link to an on-line article regarding the PHP front-end
to ImageMagick.
- coders/icon.c (ReadIconImage): Add support for Windows
.CUR format based on advice from Jean Piquemal.
- magick/image.c (SetImageInfo): Added missing CloseBlob
in error path for failure to allocate temporary file.
- coders/pcx.c (ReadPCXImage): Added support for reading
uncompressed PCX images based on code from Jean Piquemal.
2003-05-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/effect.c (AddNoiseImage): For gray images, wrong
pointer was being used to evaluate intensity, leading to a
black image with noise.
- magick/image.c (ChannelImage): Return the channel
image in RGBColorspace. Also properly support extracting
the opacity channel for images which are not CMYK.
2003-04-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/Makefile.am (install-data-local): Install
magick_config_api.h rather than magick_config.h.
- magick/api.h: Removed inclusion of integral_types.h from
magick/api.h. It is included by magick/studio.h.
- magick/delegate.h: Mapped out a block of private implementation
code.
- configure.ac: Perform substitutions on magick_config_api.h.
- magick/magick_config_api.h.in: New header file template to
use for installed magick_config.h.
- magick/studio.h (MAGICK_IMPLEMENTATION): Added the define
MAGICK_IMPLEMENTATION used to enable private types, includes, and
defines in the headers. This supports hiding implementation stuff
that API users shouldn't see in the headers.
- utilities/Makefile.am (check): Cleaned up the utilities
test/demo a bit as well as using the undocumented "tmp:" prefix to
cause GraphicsMagick to remove temporary input files once they
have been read. This leaves just the final output file
"demo.miff" when the test completes.
- coders/jpeg.c (WriteJPEGImage): If the image resolution is
overwritten with 72DPI, make sure that the resolution units are
set to PixelsPerInchResolution.
- coders/jpeg.c (WriteJPEGImage): Don't overwrite the image
resolution if it is valid.
- magick/command.c (MogrifyImageCommand): Added -resample
option to match documentation.
- VisualMagick/configure: Added rpcrt4.lib to project settings
for Visual C++ 6.0 so that configure links. The code which
needs these interfaces is to support Visual C++ 7.0 XML-style
project files.

- utilities/Makefile.am (check) Change % to %% in -label parameter.
- www/gm.html, utilities/gm.1, etc. Documented use of %% to convey
the % sign in -format, -comment, -label strings.
2003-04-30 William Radcliffe <billr@corbis.com>
- magick/command.c: Changes from 2003-04-19 to free the arg
list when it was still pointed to by the option arg and accessed
on an exception. This caused gm to crash on any erroneous command
line argument.
2003-04-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- www/windows.html: Updated to match current installer.
- VisualMagick/installer/inc/tasks-install-devel.isx (Name):
Added an installation checkbox so the user can select to install
development headers and libraries for C & C++.
- VisualMagick/installer/inc/files-perlmagick.isx (Source):
Only install PerlMagick PPD files if the user selects to install
PerlMagick.
- VisualMagick/installer/inc/files-com.isx (Source): Only
install ImageMagickObject files if the user selects to install
ImageMagickObject.
- magick/version.h.in: Added some documentation for the
functioning of MagickLibVersion and MagickLibVersionNumber.
- configure.ac: Perform substutions to create
VisualMagick/installer/inc/version.isx from
VisualMagick/installer/inc/version.isx.in. This allows Windows
versioning info to be updated from info in version.sh.
- Makefile.am (magick-version): For a VPATH build, update
VisualMagick/installer/inc/version.isx in the source directory if
it is out of date.
2003-04-28 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- magick/cache.c: CloneImagePixels(): applied Cristy's bugfix
from IM-5.5.7.
2003-04-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- www/api.html: The demo program on the ImageMagick API page is
usually intended to be an exercise for the reader. It rarely
compiles or works. Sure enough the demo code was not even close
to compiling, didn't run, and did something totally different than
described. This is not a good way to treat new users. Now the
demo program compiles and runs, and its description is correct.
- www/magick.css, www/smile.c: Remove "Pair" advertisement which
was discovered appended at the end of these files.
- coders/jpeg.c (ReadJPEGImage): Check for failure of
AllocateImage. Close blob prior to error return.
- configure.ac: Perform substitutions on magick/version.h
- magick/version.h.in: New file to provide base for configured
magick/version.h
- version.sh (PACKAGE_RELEASE_DATE): Support setting a package
release date.
- configure.ac: Perform substitutions on PerlMagick/Magick.pm.in to
create PerlMagick/Magick.pm.in.
- PerlMagick/Magick.pm.in: @PACKAGE_VERSION@ is substituted while
configuring PerlMagick/Magick.pm.
- magick/magic.mgk, VisualMagick/bin/magic.mgk: Removed risky
entry for PICT which has been demonstrated to lead to a false
match in the real-world.
- coders/pict.c (ReadPICTImage): Ensure that PICT decoder don't
loop forever with an EOF condition if none of the PICT op-codes
encountered result in a condition which terminates the input loop.
If EOF is dectected while in the input loop a "corrupt image"
"unexpected end of file" error is reported.
- VisualMagick/installer: Updated installer.
2003-04-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/magick.c, magick/blob.c, magick/studio.h: Added
Compilation fixes recommended by Harold Bien for for Borland C++.
- www/contribute.html: Added text regarding contributing to
GraphicsMagick.
- www/api/types.html: Documentation for GraphicsMagick API types
moved from www/api/types/*.html into this one file. Types
documentation is still very much under development.
- README.txt: Added note regarding the download location for free
Windows fonts which are kindly made available by Microsoft.
- VisualMagick/installer/gm-dynamic-full-*.iss: Install
nt_base.h and nt_feature.h.
2003-04-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- www/windows.html: Updated for GraphicsMagick 1.0 and to
link to ImageMagickObject.html.
- www/programming.html: Added link to ImageMagickObject.html.
- www/ImageMagickObject.html: New file to provide some
documentation for ImageMagickObject.
- www: Found and fixed broken URL links.
2003-04-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- FlashPIX: Applied patches from FreeBSD. Bumped package
version to version to 1.2.0.8.
- www/api.html: Updated to reflect GraphicsMagick
- www/*.html: Updated with format_c_api_docs script.
- Makefile.am (format_c_api_docs): Add a target to update
the C API documentation.
- scripts/format_c_api_docs: Add script which extracts and
formats the C API documentation into HTML files in the www/api
subdirectory.
2003-04-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- version.sh (PACKAGE_VERSION): Update release version ID.
- magick/version.h (MagickReleaseDate): Update release date.
- magick/constitute.c (ConstituteImage): Fixed problems with
reading intensity (gray) pixel arrays.
- magick/image.c (GrayscalePseudoClassImage): Use
ScaleQuantumToIndex rather than ScaleQuantumToMap.
- magick/constitute.c (ConstituteImage): Use ScaleQuantumToIndex
macro to scale integral intensity values to colormap range.
- magick/image.h (ScaleQuantumToIndex): New macro to scale a
quantum to the maximum range of a colormap index. Useful when
writing to PsuedoClass grayscale images.
- VisualMagick/tests/run_constitute.bat: Batch script to run
constitute tests.
- VisualMagick/installer/*.iss: Updated for Beta1 release.
2003-04-22 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- utilities/Makefile.am (check) fixed typos (RM -> RMDelegate
and removed stray "gm"), added -random-threshold, ordered-dither.
- magick/effect.c: Random-threshold was not treating non-gray
PseudoColor images correctly.
2003-04-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- utilities/Makefile.am (check): Added code to put logo on demo
output.
- magick/command.c (MontageImageCommand): Pass exception rather
than &image->exception because image may be null, and it is
pointless to store the exception where it will not be reported to
the user anyway.
- utilities/Makefile.am (check): Ported Glenn Randers-Pehrson's
utilities demo script into the Makefile to serve as a check
target.
(check): Add definition to find Generic.ttf.
- locale/C.mgk: Fixed syntax error in <Option><FatalError>
section.
- www/development.html: New file to describe development
process.
- index.html, www/*.html: Added link to development.html
and improved formatting a bit.
2003-04-21 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- Fixed bug with compiling png.c with libpng versions
older than libpng-0.95.
2003-04-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- www/programming.html: Added links to Delphi and Scheme
programming interfaces.
- configure.ac : Removed outdated test for jp2conf.h.
2003-04-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c: Add argument expansion and deallocation code
to command functions which lacked this functionality.
Replace calls to Exit with a return to the invoking function.
- utilities/gm.c: Expect each subcommand to expand and deallocate
its own argument list. Treat subcommands more similarly.
- magick/magick.c (InitializeMagick): Seed the random number
generator.
- magick/utility.c (ExpandFilenames): Handle tilde expansion
properly. Handle relative glob specifications. Skip over "*"
argument to +profile properly. Don't expand VID: specifications
since the VID: coder will execute ExpandFilenames() later. Apply
format specifier prefix to globbed file names. Fix double frees
and rationalize memory management by always copying to a new
vector.
2003-04-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/magick.c (InitializeMagick): Decided to
move clean-up signal-handler registration from gm.c
to magick.c in order to ensure that resources are
cleaned up for all library users. This means that
if a user program wants to do something special for
signals registered to be caught by InitializeMagick
(SIGHUP, SIGINT, SIGQUIT, SIGABRT, SIGTERM, SIGXCPU,
& SIGXFSZ) then the user program should register its
own signal handlers after invoking InitializeMagick.
The user is then responsible for making sure that
DestroyMagick is invoked if an unexpected signal is
caught.
- tests/Makefile.am (check-constitute): Added
constitute tests.
- magick/constitute.c: New test program to ensure
that ConstituteImage and DispatchImage are working
correctly.
2003-04-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- www/download.html: Added links to directories
at ftp.graphicsmagick.org.
- index.html: Add notice regarding 1.0 Beta0
availability.
- www/cvs.html: Updated CVS checkout information to
include the GraphicsMagick-1_0 branch.
- coders/psd.c (ReadPSDImage): Applied patch
(SourceForge patch ID 722849) from Derry Bryson to
fix a memory leak. An image was being leaked.
- magick/constitute.c (DispatchImage): Applied patch
(SourceForge patch ID 722655) from Derry Bryson to
correctly use the switch_map array rather than the
map array. Without this patch, DispatchImage does
not work at all.
- GraphicsMagick 1.0.0-beta0 release.
- version.sh: Updated for beta0 release.
- *.c magick/*.h: Update header inclusion to include
"magick/" prefix in order to ensure that there is no
confusion with headers from another package.
2003-04-16 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- magick/effect.c: 4x4 ordered dither threshold was
incorrect.
2003-04-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/resource.c (InitializeMagickResources):
Added the ability to obtain the amount of physical
memory by executing an external command.
- configure.ac: Check for getpagesize().
(MAGICK_PHYSICAL_MEMORY_COMMAND): Added a test for
an external command which (quickly) returns the
amount of physical memory installed on the machine.
Currently only activated for FreeBSD.
(MAGICK_PHYSICAL_MEMORY_COMMAND): Use sysctl to
determine total physical memory for Darwin.
- magick/delegate.c (ListDelegateInfo): If COLUMNS
environment variable is set, then use it to obtain
the screen width. Some shells dynamically update
COLUMNS, but COLUMNS may need to be explicitly
exported in order for it to be seen by subordinate
programs (such as gm).
- magick/effect.c (AddNoiseImage): Use IsGrayImage()
to check if the image is gray. Add missing columns
loop for intensity case (oops!).
- magick/command.c (DisplayImageCommand): Fix
-dispose option processing bug reported by
Felix Heimbrecht.
- coders/fpx.c: Check status from FPX_InitSystem().
2003-04-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Define PERLMAINCC to be the C compiler
if there are no C++ dependencies, or the C++ compiler
if there are C++ dependencies.
- PerlMagick/Makefile.PL.in: Use PERLMAINCC to compile
and link perlmain.c. This allows using the C++ compiler
to link, which is useful when the build depends on C++
libraries like libfpx.
- ltmain.sh: Updated to libtool 1.5 release.
- Makefile.am ($(PERLMAGICK)/$(PERLSTATICNAME)): Add
rules to make sure that static PerlMagick is linked
against the current GraphicsMagick library.
- coders/miff.c (ReadMIFFImage): Properly scale
colormap entries.
- magick/image.c (TransformRGBImage): Eliminate 32-bit
integer overflow condition for Q:32 build while
transforming CMYK pixels.
2003-04-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/t/ttf/read.t: Updated signatures and
reference image for FreeType 2.1.4.
- (PerlMagick/t/write.t, PerlMagick/t/montage.t,
PerlMagick/t/rad/read.t, PerlMagick/t/rad/write.t):
Fix signatures which were thrown off by previous
change to how signatures are specified to functions
in subroutines.pl.
- PerlMagick/t/cgm/read.t: Updated to use reference
image.
- PerlMagick/Makefile.PL.in: Perform substitutions
on generated Makefile to ensure that the proper
-lGraphicsMagick is used for a static build.
- ttf: Updated to FreeType 2.1.4. Now stored in
CVS as delegates/freetype2 rather than delegates/ttf
so be sure to re-checkout the ttf directory so that
the correct files are used.
- wmf/incude/libwmf/api.h: Updating FreeType caused
a problem since it introduced a copy of zlib and
api.h included zlib.h. Fixed problem by adding
a typedef for gzFile and not including zlib.h.
- utilities/gm.c: Fixed minor compilation problem
under Windows caused by a typo in the signal
handler registration code.
2003-04-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Makefile.am: When building a static PerlMagick,
build PerlMagick as part of the 'all' target and
don't do a 'make clean' of PerlMagick at install
time.
- configure.ac (LIB_DPS): Add check to see if -lXt
is required by -ldps. XFree86 -ldps requires -lXt.
- FlashPIX: FlashPIX library now compiles under
FreeBSD 5.0.
- magick/deprecate.c (ValidateColormapIndex): Remove
non-interface deprecated function.
- magick/tempfile.c (AcquireTemporaryFileDescriptor):
Priortize use of mkstemp() over tempname() since *BSD
compilers whine about tempname() (although we do use
tempname() safely).
- magick/color.c (ConstrainColormapIndex): Removed
function since it is no longer used.
- magick/utility.c (TemporaryFilename): Removed
TemporaryFilename utility function since it is
no longer used and it makes *BSD compilers
complain.
- magick/studio.h: Don't define _ISOC99_SOURCE,
_POSIX_C_SOURCE, or _XOPEN_SOURCE when compiling
under FreeBSD since this maps out a 'ushort'
definition required by /usr/include/sys/ipc.h.
2003-04-11 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/png.c: Some grayscale PNG images and the
JNG alpha channel were decoded improperly at Q:32.
- magick/constitute.c (PopImagePixels): Changed many
instances of (Quantum) typecast to (unsigned char).
2003-04-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/t/tiff/read.t: Added signature for 12-bit
TIFF test and a Q:32 build.
- PerlMagick/t/subroutines.pl: Extended routines
which are signature based to accept signatures for
Q:32 as well.
- PerlMagick/t/wmf/read.t: Relax error values slightly
to pass at Q:32.
- coders/miff.c (PushImageRLEPixels): Fix reading
RLE MIFF at Q:32. A fragment of old code was being
used to obtain the length.
(WriteRunlengthPacket): Fix writing RLE MIFF at Q:32.
In most cases the wrong scaling macro was being used.
- tests/Makefile.am (check-miff): Added MIFF tests
for supported compression options.
2003-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/color.c (QueryColorDatabase): Extended to
support parsing Q:32 hex color specification strings.
Also add error reporting for failure to parse the
color specification. This resolves a bug that drawing
via the draw.c APIs was not working for Q:32 builds.
- utilities/gm.c (main): Add signal handlers to
make sure that program cleans-up on exit by invoking
DestroyMagick.
- magick/draw.c (DrawSetFillColor): Quote color
specification.
(DrawSetStrokeColor): Quote color specification.
(DrawSetTextUnderColor): Quote color specification.
- ltmain.sh: Update to latest CVS libtool.
2003-04-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/enhance.c (NormalizeImage): Only normalize the
opacity channel if image->matte is true. This results
in some (15%) speedup. While it can be argued that the
'K' in CMYK should be normalized, it can also be argued
that this is senseless since 'K' is not a "linear" measure
like C, M, & Y are, and there may not be any any value
to normalizing CMY at all.
(EqualizeImage): Only equalize the opacity channel if
image->matte is true. This results in a 23% speedup.
(GammaImage): Minor loop optimization.
(LevelImage): Don't level the opacity channel. Doing so
doesn't make any sense.
(LevelImageChannel): Put loops inside switch statement
rather than around it.
- PerlMagick/t/tiff/read.t: Added grayscale 12-bit and
16-bit TIFF read tests.
2003-04-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (ReadTIFFImage): Add support for reading
12-bit grayscale TIFFs. Fix reading 16-bit grayscale TIFFs
when QuantumDepth=8.
- VisualMagick/installer/gm-dynamic-full-8.iss,
VisualMagick/installer/gm-dynamic-full-16.iss: Many C header
files were not being included in the distribution. Oops!
2003-04-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- (index.html, www/*.html): Update to new web page style.
- scripts/txt2html: Update to output new web page style.
- ltmain.sh: Updated to latest CVS libtool.
- magick/tempfile.c (DestroyTemporaryFiles): Function was
crashing if it was executed twice.
2003-04-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/delegates.mgk.in: Ralcgm was appending ".ps" to the
provided output file name, so change cgm delegate command so that
the input file is delivered via standard input, output is
re-directed to a file, and anything printed to stderr (such as
the Ralcgm program name and version) is sent to /dev/null.
- INSTALL-unix.txt: Added/corrected/improved documentation
regarding --disable-installed, --enable-shared, and
--with-modules.
- VisualMagick/magick/magick_config.h.in: Add more documentation
and explanatory notes in order to lessen confusion.
- Many files: Replaced "UseInstalledImageMagick" with
"UseInstalledMagick" for obvious reasons.
2003-04-04 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- magick/command.c, utilities/gm.c: Print "help" screen for a
tool when user types "gm tool" or "gm tool -help"
- magick/command.c, magick/effect.c: add -ordered-dither option.
2003-04-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- locale/C.mgk: Fixed message associated with
"UnableToCreateTemporaryFile".
- magick/tempfile.c (AcquireTemporaryFileDescriptor): Decided
to return a pathname (if possible), even on failure, for use
in error reports. The function return status should be used
to determine if the function has succeeded.
- locale/locale.mgk: Updated copyright header.
- (magick/annotate.c, magick/attribute.c, magick/blob.c,
magick/cache.c, magick/constitute.c, magick/delegate.c,
magick/display.c, magick/image.c, magick/locale.c
magick/tempfile.c, magick/tempfile.h, magick/utility.c,
magick/xwindow.c, coders/dcm.c, coders/ept.c,
coders/histogram.c, coders/mpeg.c, coders/pdf.c,
coders/pict.c, coders/preview.c, coders/ps2.c,
coders/ps3.c, coders/ps.c, coders/pwp.c, coders/sfw.c,
coders/svg.c, coders/tiff.c, coders/url.c, coders/wpg.c):
Ensure that failure to allocate/create temporary file is
properly detected and reported.
2003-04-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/type.c (GetTypeBlob): Prioritize hard-coded path
over Windows registry values.
- magick/log.c (GetLogBlob): Prioritize hard-coded path
over Windows registry values.
- magick/blob.c (GetConfigureBlob): Prioritize hard-coded path
over Windows registry values.
- magick/delegate.c (ReadConfigureFile): Perform substitutions
for "@GMDelegate@", "@GMDisplayDelegate@", "@MPEGDecodeDelegate@",
"@MPEGEncodeDelegate@", and "@HPGLDecodeDelegate@" while reading
delegates.mgk under windows.
(ListDelegateInfo): Format delegate command line to multiple
lines if necessary rather than truncating.
- configure.ac (MagickBinPathDefine): Added support for
a MagickBinPath definition.
- configure.ac (GSVersion): Added test to obtain version
of installed Ghostcript.
- magick/tempfile.c (AcquireTemporaryFileDescriptor): Open
flag should have been O_RDWR, not O_WRONLY!
2003-04-03 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- magick/utility.c: Simplified skipping over the "*" in
the +profile "*" option when expanding filenames.
2003-04-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/bin/delegates.mgk: Update similarly to
coders/delegates.mgk.in.
- coders/delegates.mgk.in: Replaced 'mpeg-decode' delegate
specification with 'mpeg' delegate specification.
- PerlMagick/t/mpeg/read.t: Since -r option is no longer
supplied to mpeg2decode, the signatures must be updated.
- magick/utility.c (ExpandFilenames): Skip over no-argument
commands properly.
- coders/mpeg.c: Removed ReadMPEGImage since this is handled
entirely by delegate now.
- magick/command.c: Add convert -temporary option for use
when input files are temporary files which should be
automatically removed.
- magick/delegate.c (InvokeDelegate): Ensure that temporary
file access is secure.
- coders/ept.c (ReadEPTImage): Ensure that temporary file
specified by image_info->filename is liberated before
allocating a new temporary file name.
- coders/ps.c (ReadPSImage): Ensure that temporary file
specified by image_info->filename is liberated before
allocating a new temporary file name.
- coders/pdf.c (ReadPDFImage): Change TemporaryFilename
to AcquireTemporaryFileName.
- magick/tempfile.c (LiberateTemporaryFile): Now takes
a 'char *' argument rather than 'const char *', and
erases the provided filename if it is the name of a valid
temporary file. This helps avoid errors. The return
status may be used to determine if a file was removed.
(AcquireTemporaryFileDescriptor): Decided that adding a
.tmp extension to temporary file names is unnecessary.
- coders/jp2.c (WriteJP2Image): Destroy pixel matrix
after encoding image. Cristy says that there is memory
corruption otherwise.
2003-04-01 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- coders/png.c: Use new temporary file manager for JNG components.
Merge with IM 5.5.7 (mostly cosmetic changes).
2003-03-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/cache.c (OpenCache): Add some Windows-specific
open options.
- magick/resource.c (InitializeMagickResources): Increase
the number of "lowio" file handles available for use under
Windows.
- ltdl/ltdl.c: Incorporate more Darwin fixes from CVS libtool.
- coders/pcx.c (ReadPCXImage): Incorporate bugfix from
ImageMagick -- Not enough memory allocated for reading PCX
(bug report by Trevor Willis).
- magick/magick.c (InitializeMagick): Only invoke
SetLogEventMask() to set debug options based on
getenv("MAGICK_DEBUG") if the environment variable is set.
2003-03-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/tempfile.c: Include tempfile.h rather than temporary.h
- magick/magick.c: Include tempfile.h rather than temporary.h
- coders/dcm.c, coders/ept.c, coders/histogram.c, coders/mpeg.c,
coders/pdf.c, coders/pict.c, coders/preview.c, coders/ps.c,
coders/ps2.c, coders/ps3.c, coders/pwp.c, coders/sfw.c,
coders/svg.c, coders/tiff.c, coders/url.c, coders/wpg.c,
magick/annotate.c, magick/attribute.c, magick/blob.c,
magick/cache.c, magick/constitute.c, magick/delegate.c,
magick/display.c, magick/image.c, magick/magick.c,
magick/utility.c, magick/xwindow.c: Updated to use new temporary
file allocation APIs.
- magick/tempfile.c: New temporary file allocation subsystem for
allocating, tracking, and deallocating temporary files. Use of
this subsystem should reduce the likelyhood that temporary
files will be left behind once the process exits.
If the environment variable MAGICK_TMPDIR is set, then its
value is used as the location to place temporary files.
- magick/utility.c (IsAccessibleAndNotEmpty): New function
for testing for file exists, is a regular file, and is not empty.
Used to test if a temporary file has been updated by a delegate.
- magick/log.c (SetLogEventMask): Add support for setting
TemporaryFileEvent.
- PerlMagick/Magick.xs: Added TemporaryFile log event type.
- magick/log.h (LogEventType): Add TemporaryFileEvent event
classification.
2003-03-29 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- magick/resize.c (SampleImage) and magick/render.c (DrawAffineImage():
Applied Cristy fix for bug that offset images to the top and left.
- magick/resize.c (ScaleImage): Fixed bug that caused intensity
levels to be one unit too high.
- coders/png.c: make JNG support depend on HasJPEG. Remove temp files.
2003-03-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/resize.c (ResizeImage): Applied fix authored by John
Cristy for distortion when using the bessel filter.
- magick/display.c: Applied fix authored by John Cristy which
eliminates bogging down when using the magnifier window on
large images.
- Several files: A few files included multiple copies of the
copyright header text due to either pilot error, or equipment
failure.
2003-03-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- tests/Makefile.am : Removed some debug code which was
accidentally committed to CVS.
- Copyright.txt: Add copyright statements to all the files,
including some apparently missing copyrights.
2003-03-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/Makefile.am: Added temporary.c and temporary.h. These
are not finished yet.
- magick/cache.c: Transferred optimization from ImageMagick
to read/write all requested pixel cache rows in one system
call when accessing the cache using file I/O, and the
requested columns equals the image columns.
- magick/resource.c: (ResourceInfo): Use type 'double' rather
than 'long double'. For many systems, the range of 'long double'
is the same as 'double'. On others, use of 'long double' incurs
the cost of function calls since there is no hardware support.
2003-03-22 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- magick/effect.h, effect.c, command.c: Revised -random-dither
to require parameters: channel LOWxHIGH. Channel can presently
be "intensity", "opacity", or "all".
2003-03-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- ltdl/ltdl.c: Updated to latest CVS version. Claimed to
support loading modules under MacOS-X.
- magick/resource.c (InitializeMagickResources): Enable code
under Windows which queries system limits.
- magick/cache.c (S_MODE): Fixed portability problems with

- magick/blob.c: Fix some erroneous log printf specifications.
Improved blob log messages a bit.
- magick/log.c (IsEventLogging): Use InitializeLogInfo().

This approach should avoid deadlocking while logging from functions
used to initialize logging.
(IsLogAccessible): No longer need this duplicate of IsAccessible().
(SetLogEventMask): Use InitializeLogInfo().
- coders/fpx.c (ReadFPXImage): FlashPIX library does not support

- coders/jp2.c (WriteJP2Image): Quality factor calculation had
accidentally been removed. The calculation is back, but has been
biased up slightly so that a quality factor of 75 results in a
more reasonable 16:1 compression. Past a quality factor of 99.5,
the compression is set to 1:1 (non-lossy).

should save their original values before processing the image
and restore them when processing is complete, or transfer them
from the input image to the output image.

2003-02-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/nt_feature.c (CropImageToHBITMAP): Remove useless
autocrop support which was transferred from CropImage when
creating CropImageToHBITMAP.
2003-02-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/miff.c (ReadMIFFImage): RLE packet size was not

depth>8 to not be read.
2003-02-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/paint.c (ColorFloodfillImage): Transfered fix from

- coders/svg.c (SVGStartElement): Applied fix from ImageMagick to
compute SVG +> MVG viewbox correctly.
- magick/image.c (CloneImage): Applied fix from ImageMagick which
is purported to solve the problem that "negative (x,y) page offsets
did not clone properly".
- magick/gem.c (TransformHWB): Replace implementation with
ImageMagick's new version which is supposed to fix a rounding
error problem. Hard to say since implementation is totally
different.
- coders/msl.c (MSLStartElement): Applied fix for missing break
from ImageMagick.
- magick/integral_types.h: New header to include the integral
types typedefs. Needed new header in order to include in both
studio.h and api.h at the right point.
- magick/studio.h: Move nt_feature.h inclusion to the few modules
which actually use functions from it.
- magick/api.h: Added typedefs gm_int16_t, gm_uint16_t,

Q:16. Much faster than floating point!
2002-01-28 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- Fixed bug in png.c, introduced in IM-5.5.1. A pair of
{ } brackets were omitted when logging was added, which lets
old versions of libpng write a zero-length iCCP chunk.
2003-01-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/effect.c (DespeckleImage): Put loops inside of case
statement rather than outside.

image_info->dither.
- magick/image.c (SetImageType): For case BilevelType, normalize
image, and threshold 50% if dithering is disabled. This is at
least 10X faster than quantizing with dither.
(AllocateImage): Initialize image->dither.
(CloneImage): Copy image->dither.
- magick/image.h: Added dither member to Image.
2003-01-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2003-01-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/gem.c (Hull): Count down loops. Might help.
(InterpolateColor): Pre-compute common sub-expressions to improve
performance.
- magick/segment.c (Classify): Implemented idea from Glenn
Randers-Pehrson to avoid use of pow() when WeightingExponent is
2.0 (which it is). This makes image segmentation much faster
(e.g. 8X).
- magick/annotate.c (RenderFreetype): For images with
matte==False, simply set the opacity of the pixel to be updated to
OpaqueOpacity before alpha-compositing the pixel rather than using
SetImageType(TrueColorMatteType) to initialize the opacity of the
entire image. This is much faster and scales to large images.
- magick/image.c (SetImageType): Eliminated unnecessary conditionals.
2003-01-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/effect.c (InsertMedianList): Assign computed quantum

not display correctly.".
- coders/miff.c (ReadMIFFImage): Reading RLE-compressed MIFFs is
now about 4X faster.
- magick/blob.c (OpenBlob): Use setvbuf() to increase stdio buffer
size to 16K. Solaris default is 1K. This should minimize system
call overhead for accessing large files.
(ReadBlob): "Manually" copy data rather than using memcpy() for
very small copy sizes.
(ReadBlobZC): New method, similar to ReadBlob, but provides the
opportunity for zero copy on read.
- magick/constitute.c (PushImagePixels): CMYKA case for
image->depth=16 was comparing with 8 instead.
2003-01-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

'~' geometry string flag. This also fixes a montage bug in which
thumbnails were mis-sized if the geometry specification incuded x
or y offsets.
- magick/image.h (GeometryFlags): Added CenterValue enumeration to
correspond with new '~' geometry string flag. Taking
ImageMagick's lead on this.
- magick/render.c: Transferred fixes from ImageMagick for an
artifact which occured at the 360 degree point when rendering
circles, ellipses, and arcs. Bug reported by io219@attbi.com.

the GraphicsMagick Group rather than ImageMagick Studio.
- magick/constitute.c (ConstituteImage): Simplified the switch
statement for inner loops by creating a simplified map in advance.
(DispatchImage): Simplified the switch statement for inner loops
by creating a simplified map in advance.
- magick/compress.c (HuffmanEncodeImage): Test and cache the
return value of LocaleCompare(image_info->magick,"FAX") so that
LocaleCompare is not executed repeatedly in the output loop.

(IsMonochromeImage): Optimized loops.
(IsOpaqueImage): Optimized loop.
- magick/delegate.c (InvokePostscriptDelegate): When using the
Ghostscript library, identify the library as "[ghostscript library]"
rather then "gsdll32" so that -verbose prints something useful for
both Windows and Unix.
2003-01-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- NEWS: New file.
- magick/montage.c (MontageImages): Use ThumbnailImage() rather
than ZoomImage() to resize montage thumbnails provided that the
user has not specified an image filter, and the montage thumbnail
is smaller than the image. This should provide faster montages
for large images.
- magick/resize.c (ResizeImage): Added logging support.
(MagnifyImage): Added logging support.
(MinifyImage): Added logging support.
(SampleImage): Added logging support.
(ScaleImage): Added logging support.
2003-01-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/transform.c (ProfileImage): Duplicate ImageMagick changes
to image colorspace handling. Avoids using
SetImageType(image,ColorSeparationMatteType).
- magick/fx.c (OilPaintImage): Replaced with ImageMagick version
since ImageMagick version has been updated to not penalize Q:8.
Optimized loops.
- magick/display.c (XDisplayImage): Display to 100% of
the screen size rather than 90% of the screen size.
- magick/enhance.c (ModulateImage): Ensure that arguments
are always positive values. Optimized loops.

and TransformHSL can be inlined. No longer check/correct
negative values.
2003-01-14 William Radcliffe <billr@corbis.com>
- magick/blob.c
- magick/blob.h
Added new stream type flag and support to match with the one
added to ImageMagick.
2003-01-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/constitute.c: Minor optimizations to PopImagePixels()
- coders/dpx.c: Reading the DPX header was off by 4 bytes.
- coders/(art.c,avs.c,bmp.c,cmyk.c,dcm.c,dib.c,dpx.c,fax.c,
fits.c,gray.c,icon.c,map.c,miff.c,mono.c,mpc.c,mtv.c,otb.c,

yuv.c): Ensure that blob is closed on unexpected EOF.
- magick/image.c: Optimized SetImageOpacity().
Optimized SetImage() for intializing non-opaque images. The
opacity channel was being intialized twice.
2003-01-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/constitute.c: Log entry and exit from coders so that
coders don't need to.
- Finished re-writing PushImagePixels() using coding practices
which may result in faster code.
- PerlMagick is changed from Image::Magick to Graphics::Magick
in order to avoid conflicts with the ImageMagick version. This
means that any Perl scripts based on the ImageMagick version need
to do a global replace of Image::Magick to Graphics::Magick.
- PerlMagick/reference/filter/Raise.miff: Replaced with new version.
2003-01-08 William Radcliffe <billr@corbis.com>
- magick/nt_feature.c

compares with a reference image rather than comparing with a
signature.
- PerlMagick/t/wmf/read.t: Ditto.
magick/shear.c: Fixed documentation for RotateImage.
2002-01-08 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

2003-01-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/svg.c: Allow the user to specify the initial background
color via the -background option. This is only useful if the SVG
doesn't draw its own background rectangle.
2003-01-06 Albert Chin-A-Young <china@thewrittenword.com>
- ltdl/Makefile.am, ltdl/ltdl.c: Fix compilation problem
under Tru64 UNIX 5.1. The GraphicsMagick random.h was being
included when the system random.h was needed.
- configure.ac: Improve robustness of POSIX thread API tests
by including pthread.h when building the test program.
2003-01-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c: In IsImagesEqual() only use type 'long double'
for error summation if QuantumDepth > 16 and 'long double' has
more range than 'double'.
- magick/quantize.c: In QuantizeImage() only use type 'long
double' for error summation if QuantumDepth > 16 and 'long
double' has more range than 'double'.
- Replaced redundant code with macros.
- Optimize mapping to monochrome.
- utilities/conjure.c: Had missed removing this file earlier.
2003-01-04 Derry Bryson <dbryson@techass.com>

requested when antialiasing is disabled (bug fix).
2002-12-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c: For TransformRGBImage() and RGBTransformImage()
round values to int when creating tables rather than using scaling
to avoid rounding.
2002-12-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/png.c: Fixed compile problems.
- magick/image.c: SyncImage() performance optimizations.
- TransformRGBImage() cleanup/enhancements. Some rounding issues remain.
- RGBTransformImage() cleanup/enhancements. Some rounding issues remain.
2002-12-24 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- BUGFIX: Fixed bug, introduced on 12/18/02, in which a misplaced
"}" caused an assertion failure after reading any opaque JNG image.
- Added CloseBlob before returning a NULL JNG image.
- Merged png.c with IM-5.5.3-1, including a seemingly pointless
rename of SaveImageText string to SaveImageTag.

- magick/nt_feature.c: Ensure that image is RGB prior to transfer
to HBITMAP.
2002-12-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c: Re-worked TransformRGBImage() again so that it
is now smoking fast for Q:8 and Q:16. Changed lookup tables, and
all per-pixel transforms to use only integer arithmetic. A
pre-multiplication scheme is used which should actually improve
the quantization error over using double arithmetic. It is
actually possible to improve Q:32 performance a bit more but is
it worth the effort?
2002-12-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c: Implemented logging for TransformRGBImage()
and RGBTransformImage().
2002-12-24 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- The png codec would close the blob twice (second time raising an
assertion) if a libpng error was encountered.
- Sometimes the PNG writer would receive an invalid bit depth from
CompositeImages(); this is now ignored.
2002-12-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c: Re-wrote TransformRGBImage() so that it
does not penalize a Q:8 build. The function should be
faster now, but no timings have been made to verify that.
2002-12-21 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- Elimimated unused transparent_pixel array in png.c.
- Reverted to incrementing loops in bmp.c where the counter
"i" is used in the loop.
2002-12-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c: Update MogrifyImage() so that gm is 9X
faster when transforming a color image to grayscale.
2002-12-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Updated coders to use VerifyColormapIndex macro rather
than slow ConstrainColormapIndex() function.
- magick/constitute.c: Trial use of VerifyColormapIndex
in PushImagePixels() IndexQuantum case.
2002-12-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/color.c: Added VerifyColormapIndex macro to
verify range of color index without a function call.

2002-12-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/bmp.c: Sped up RLE expansion and sped up byte-size
PseudoColor scanline conversion. Results in 50% speed-up
when running on SPARC.
2002-12-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- utilities: Removed legacy ImageMagick utilities which
have been rolled up into gm.c/command.c.
2002-12-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/Magick.xs: Fixed FormatString() format
problems identified by the compiler.
2002-12-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.h: Moved function prototypes for functions
implemented in code modules other than image.c to seperate
header files with names based on the implementation files.
2002-12-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/enhance.c: Report appropriate message while leveling
image.
2002-12-18 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
- Sync png.c and fx.c with IM-5.5.3. "gm convert -list format"
now includes zlib version info among the PNG info.
- ConvolveImage() logs kernel info as a "Transform" debug event.
- ReadJNGImage() now skips decoding JPEG subimage when "pinging"
2002-12-17 Cristy <cristy@mystic.es.dupont.com>
- * SVG element 'stroke-dasharray: 0' no longer causes a
segmentation fault.
2002-12-17 Cristy <cristy@mystic.es.dupont.com>
- CoaleseceImage() properly handles a dispose method of
BackgroundDispose.
2002-12-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Updated to substitute for @GMDelegate@.
- magick/effect.c: Changed AdaptiveThresholdImage offset
to double so that it works with QuantumDepth=32. Thanks
to Glenn for pointing out this problem.
- magick/image.c: Adapted to AdaptiveThresholdImage API
change.
- magick/image.h: Annotated global constants and functions
with the name of the source file where they are implemented.
This is in preparation to break up image.h into multiple
header files to diminish unnecessary header dependencies.
- coders/delegates.mgk.in: Updated to use @GMDelegate@
definition and 'gm' program rather than ImageMagick utility
names.
- PerlMagick/t/read.t: Converted gradient test (which was not
working at all) to compare with a reference image.
- PerlMagick/t/jpeg/read.t: Re-wrote to compare with reference
image.
- PerlMagick/t/jpeg/write.t: Re-wrote to compare with reference
image.
- magick/image.c, magick/command.c: Moved MogrifyImage and
MogrifyImages from image.c to command.c in order to diminish
unnecessary inter-object coupling. Only functions in command.c
should use MogrifyImage or MogrifyImages. Some work remains
to accomplish that.
2002-12-16 Cristy <cristy@mystic.es.dupont.com>
- coders/jpeg.c: Add missing break statements to fix
colorspace handling when image colorspace is CMYKColorspace
or YCbCrColorspace.
- magick/decorate.c: Cast to double in calculation.

a signed type.
2002-12-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Re-wrote PerlMagick filter.t tests so that they all compare
results with reference images rather than compare signatures.

return values are never used in resource limit calculation.
2002-12-12 William Radcliffe <billr@corbis.com>
- magick/magick.c
Fixed bugs in InitializeMagick, but I also heavily commented
the code so show what it seems to be doing. It appears broken
and needs testing on all platforms. Toward that end, I added
Log events so that we can see what it is doing.
2002-12-12 William Radcliffe <billr@corbis.com>
- utilities/gm.c
Fixes a crashing bug in gm.c caused by an attempt to free a bad
pointer. Added comments to the code that explain why this happens
so that future developers don't fall into the same trap.
- win2k/IMDisplay/IMDisplay.rc
Modified some of the string resources that define supported file
formats that were in error. One example was eps with had a *.eps
in the string instead of just .eps. This caused the document
class to ASSERT under the debug build.
2002-12-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Enable the module loading code for shared/DLL builds
regardless of whether the build is a "modules" build. This

GetImageMagick() to test file magic via Is* methods so that
we can learn if eliminating use of these tests causes any ill
effects.
2002-12-09 William Radcliffe <billr@corbis.com>
- Moved xtrn.c from contrib area into coders area so that it can
be used from within the COM object. This is windows only code that

confusing to users.
2002-11-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/wmf.c: Set white background of embedded bitmaps to transparent
if the image background is a texture image, not-white, or non-opaque.

- Unix binaries packages (built with --disable-installed) should now
work using the same file layout as the distribution file. There is
no longer a need to put all files in the same directory.

quote character (', ", or }) as well as backslash. The backslash
should be discarded if it was used as an escape character. In order
to reliably pass a backslash, two successive backslashes are required
(e.g. "\\").
