<p>
2003-12-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/annotate.c (RenderFreetype): Ensure that image storage
class is set to DirectClass. Text rendering was not working
properly on top of PseudoClass images.
<LI> magick/map.c (MagickMapRemoveEntry): Logic didn't properly
handle removing entry in list.<BR>
<LI> configure.ac: Added --enable-efence option to enable memory
debugging using Electric Fence.
</UL>
<p>
2003-12-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> tests/maptest.c (main): Extended test to add an entry to the
list after an entry has already been removed.
<LI> magick/image.c (ColorspaceTypeToString): Add support for LAB
colorspace.<BR>
<LI> 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.<BR>
(MagickMapCopyString): Preserve a null argument, and use
AcquireString since it doesn't enlarge the string storage.
(MagickMapCopyBlob): Preserve null blobs.
<LI> configure.ac: Search for the shmctl() function. Under current
Cygwin, this is hiding in -lcygipc.
</UL>
<p>
2003-12-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/composite.c: Fixed the composite operator list in the
CompositeImage documentation.<BR>
<LI> 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.<BR>
<LI> PerlMagick/Magick.xs: Added "LAB" to colorspace types.
<LI> magick/image.h (enum ColorSpace): Add LABColorspace enumeration.
<LI> wand/magick_wand.h : Add some compatibility definitions to
translate from ImageMagick enumerations to existing GraphicsMagick
enumerations.
</UL>
<p>
2003-12-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> 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.
<LI> configure.ac: <ft2build.h> is an optional prerequisite for
<freetype/freetype.h> and <libwmf/ipa.h> so include it when
testing for these headers.<BR>
<LI> magick/annotate.c: Include <ft2build.h> if it is available.
</UL>
<p>
2003-12-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> wand/wandtest.c: Ported from latest ImageMagick version.
<LI> wand/drawing_wand.c: Adapted to be compatible with latest
ImageMagick version.<BR>
<LI> wand/pixel_wand.c: Adapted to be compatible with latest
ImageMagick version.<BR>
<LI> wand/magick_wand.c: Ported from latest ImageMagick version.
<LI> 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.
<LI> 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.<BR>
(SetImageProfile): New function to add (or remove) an image
profile. Does not execute CMS color profiles.
<LI> magick/cache.c (SetImageVirtualPixelMethod): Return unsigned int to
make the Wand implementation happy.
<LI> magick/image.c (TransformColorspace): Return unsigned int to
make the Wand implementation happy.
(SetImageType): Return unsigned int to make the Wand
implementation happy.<BR>
<LI> 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.
<LI> locale/C.mgk: Added new messages required by Wand library.
<LI> magick/error.c (ExceptionSeverityToTag): Add tag translations
for the WandWarning, WandError, & WandFatalError enumerations
<LI> magick/error.h (enum ExceptionType): Add WandWarning, WandError,
& WandFatalError enumerations to ExceptionType for ImageMagick
API compatibility.<BR>
<LI> magick/image.h (enum ChannelType): Add an 'AllChannels'
enumeration to the ChannelType enumeration for ImageMagick
API compatibility.
</UL>
<p>
2003-12-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> 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.
</UL>
<p>
2003-12-17 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
<UL>
<LI> 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.
</UL>
<p>
2003-12-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> 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.<BR>
<LI> configure.ac: Check for <ft2build.h>.
</UL>
<p>
2003-12-16 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
<UL>
<LI> 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.
</UL>
<p>
2003-12-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> 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.
</UL>
<p>
2003-12-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> 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.
<LI> PerlMagick/t/composite.t: Update Minus and Xor reference images.
<LI> 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.<BR>
<LI> magick/image.h (RoundToQuantum): Added missing parenthesis.
</UL>
<p>
2003-12-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> doc/environment.imdoc: Document MAGICK_CODER_MODULE_PATH and
<STRONG>MAGICK_FILTER_MODULE_PATH.</STRONG><BR>
<LI> 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.
<LI> 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.
<LI> Makefile.am: Updated to Automake 1.8.
(install-exec-perl): Fixes which achieve a successful
'make distcheck' for the first time in *Magick history.
<LI> configure.ac: Set scripts to executable.
</UL>
<p>
2003-12-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> Makefile.am (uninstall-data-html): Pathnames were computed
incorrectly so documentation directories were being left behind.
<LI> 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.<BR>
<LI> magick/delegate.c (ReadConfigureFile): Validate delegate paths
prior to substitution.<BR>
<LI> rungm.sh.in (top_builddir): Use a more reliable scheme for
computing location of source and build directories.
<LI> magick/Makefile.am: Improve include directory computation logic.
<LI> configure.ac: Don't override includedir. Pass user-supplied LIBS
to the linker.
</UL>
<p>
2003-12-08 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
<UL>
<LI> coders/jpeg.c: store JPEG quality as "[jpeg_quality]" attribute.
</UL>
<p>
2003-12-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> rungm.sh.in: New script to support executing uninstalled
executables.<BR>
<LI> magick/blob.c (GetConfigureBlob): New MAGICK_CONFIGURE_PATH
environment variable allows the user to specify the search path
for configuration (.mgk) files.
</UL>
<p>
2003-12-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> index.html: Added a table showing current stable release and
development version.
</UL>
<p>
2003-12-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> doc/options.imdoc (use): Describe the syntax of the -process
argument.<BR>
<LI> acinclude.m4 (AC_CHECK_CC_OPT): Add quoting in AC_CHECK_CC_OPT
definition. Change suggested by Patrick Welche
</UL>
<p>
2003-12-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/magick.c (GetMagickInfo): Fix preprocessing logic error
which caused moby shared library build to not register static
modules.
</UL>
<p>
2003-12-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/module.c (ExecuteModuleProcess): Add some logging.
<LI> magick/static.c (ExecuteStaticModuleProcess): Add some logging.
</UL>
<p>
2003-11-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> VisualMagick/installer: Add optional build support for LZW.
<LI> wand/Makefile.am: Add AUTOMAKE_OPTIONS.
<LI> configure.ac: Update to Autoconf 2.59.
</UL>
<p>
2003-11-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> VisualMagick/installer/inc/tasks-install-perlmagick.isx: Update
to reflect that the next release will use ActivePerl 5.8.1 Build
807.<BR>
<LI> 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.
<LI> configure.ac: Fixes to work with latest CVS libtool.
<LI> libtool.m4: Update to latest CVS libtool.
<LI> magick/modules.c, magick/static.c (ExecuteStaticModuleProcess):
Fix conditional compilation logic so that "moby" shared library
build works again.<BR>
<LI> magick/compress.c, magick/mac.c: Use existing SaveImageText and
LoadImageText global constants rather than separate defines.
</UL>
<p>
2003-11-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> configure.ac: Update to Autoconf 2.58.
<LI> Makefile.am: Update to Automake 1.7.9.
</UL>
<p>
2003-11-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/draw.c (DrawComposite): Base64-encoded image was not
being deallocated. Bad memory leak.
</UL>
<p>
2003-11-03 Mike Chiarappa <mikechiarappa@libero.it>
<UL>
<LI> BCBMagick: Updated installation procedure. Please read
BCBMagick/readme.txt for details.
</UL>
<p>
2003-11-03 Mike Chiarappa <mikechiarappa@libero.it>
<UL>
<LI> BCBMagick: Released DLL Version. Please read BCBMagick/readme.txt
for details about installation and/or use.
</UL>
<p>
2003-11-03 Lars Ruben Skyum <lars.skyum@stibo.com>
<UL>
<LI> 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.
</UL>
<p>
2003-11-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/locale.c (GetLocaleMessageFromID): Fix ID range checking
logic.
</UL>
<p>
2003-10-30 Lars Ruben Skyum <lars.skyum@stibo.com>
<UL>
<LI> coders/jpeg.c: changed to not write gray CMYK images as
grayscales. That would not be a valid optimization.
<LI> 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.
<LI> magick/nt_feature.c (NTIsMagickConflict): changed to accept
colon as part of the magick string, consistent with the way the
function is used.<BR>
<LI> 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.
</UL>
<p>
2003-10-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/static.c (ExecuteModuleProcess): Renamed from
ExecuteStaticModuleProcess. Only compiled if SupportMagickModules
is not defined.<BR>
<LI> magick/type.c (GetTypeBlob): Eliminated function.
(ReadTypeConfigureFile): Use GetConfigureBlob() rather than
GetTypeBlob().<BR>
<LI> 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.<BR>
(DestroyMagickModules): Added a new destroy function (simply
invokes DestroyModuleInfo()).<BR>
(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.<BR>
(OpenModule): Added logging messages.
(OpenModules): Added logging messages.
(ReadModuleConfigureFile): Use GetConfigureBlob() rather than
GetModuleBlob().<BR>
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).
<LI> 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.<BR>
(InitializeMagick): Invoke InitializeMagickModules().
<LI> 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().
<LI> 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.
<LI> config/Makefile.am: New makefile to install .mgk files.
<LI> magick/magick_config.h.in: Added MagickLibConfigPath and
MagickShareConfigPath defines.<BR>
<LI> 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".<BR>
<LI> Makefile.am: Added 'config' subdirectory to distribution. All
.mgk files are moved from 'coders' & 'magick' into this single
directory.
</UL>
<p>
2003-10-21 Mike Chiarappa <mikechiarappa@libero.it>
<UL>
<LI> magick/studio.h: small modifications to achieve DLL
compilation of library with Borland C++ Builder.
<LI> coders/ps3.c (ZLIBEncode2Image): Fixed bug. Compilation
fail when HasZLIB is undefined because parameters 5 and 6,
are undefined.
</UL>
<p>
2003-10-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> libtool.m4: Updated libtool again to CVS latest version.
Libtool required some fixes for building DLLs under MinGW.
<LI> magick/resource.c (InitializeMagickResources): Some code is
conditional based on HAVE_POPEN.
<LI> magick/utility.c (SystemCommand): Improved conditional
compilation logic.<BR>
<LI> 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.
<LI> configure.ac: Add test for _pclose(), pclose(), _popen(), and
popen().<BR>
<LI> magick/locale.c (GetLocaleMessage): Add missing MagickExport.
(GetLocaleMessageFromID): Add missing MagickExport.
<LI> 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.
</UL>
<p>
2003-10-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> VisualMagick/magick/magick_config.h.in: Added
PREFIX_MAGICK_SYMBOLS as a configuration option.
<LI> magick/module.c (_CoderInfo): Added register_function and
unregister_function members to record the module's register and
unregister function addresses.<BR>
(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.
<LI> libtool: Updated libtool files to the latest CVS version.
<LI> configure.ac: Changed define name from MAGICK_SYMBOL_PREFIX to
PREFIX_MAGICK_SYMBOLS since support is not available for
specifying an arbitrary prefix.
</UL>
<p>
2003-10-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> 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.
<LI> magick/studio.h: Include magick/symbols.h.
<LI> magick/api.h: Include magick/symbols.h.
<LI> magick/symbols.h: New header to support optionally remapping
library symbols. If MAGICK_SYMBOL_PREFIX is defined, then
library symbols are remapped.
</UL>
<p>
2003-10-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/api.h: Removed inclusion of <magick/semaphore.h> since it
is an implementation header.
</UL>
<p>
2003-10-13 Lars Skyum <lrs@stibo.dk>
<UL>
<LI> 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.<BR>
<LI> doc/brief_options.imdoc, doc/options.imdoc: Added documentation
for "-define" command line option.
<LI> doc/gmdocselect, doc/imdocselect: Changed "skipform" label in
sed scripts to just "skipf". Solaris sed had problems with the
long(?) "skipform" label.
</UL>
<p>
2003-10-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> 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.<BR>
<LI> www/links.html: Added a link to Michael Still's article
"Graphics from the command line".
</UL>
<p>
2003-10-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> coders/*.c: Updated module descriptions so that they accurately
describe the module rather than saying "Read/Write GraphicsMagick
Image Format".<BR>
<LI> 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."
<LI> magick/magic.mgk: Added a CINEON entry for the Cineon X image
format.<BR>
<LI> magick/static.c (RegisterStaticModules): Invoke
RegisterCINEONImage().<BR>
<LI> coders/modules.mgk: Map "CIN" magick to CINEON module.
</UL>
<p>
2003-10-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> locale/C.mgk: Added message for "UnrecognizedCommand".
<LI> 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.
</UL>
<p>
2003-10-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> Makefile.am: Updated to Automake 1.7.8.
<LI> various: Edits to eliminate minor issues detected by SGI C compiler.
<LI> coders/ps3.c (WritePS3Image): Variable 'value was set but never
used so it is removed.<BR>
<LI> magick/image.c (RGBTransformPacket): Removed inline request
since this function is too big to inline.
<LI> magick/animate.c (XAnimateBackgroundImage): Fixed a GCC 3.X
"type pinning" warning.<BR>
<LI> magick/display.c (XDisplayBackgroundImage): Fixed a GCC 3.X
"type pinning" warning.<BR>
<LI> magick/render.c (GetPixelOpacity): Removed inline directive. No
one in their right mind could ever imagine this function inlining
successfully.<BR>
<LI> magick/cache.c (IsNexusInCore): Adjusted so function inlines as
requested.<BR>
<LI> 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.
<LI> PerlMagick/t/composite.t: Use some reasonable error values.
<LI> magick/image.c (GetImageDepth): Added special cases for
colormapped images and monochrome images in order to improve
performance.
</UL>
<p>
2003-10-09 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
<UL>
<LI> NEWS: added info about color scaling, sampling-factor, and
changed a reference to "-coder-options" to "-define".
</UL>
<p>
2003-10-09 Lars Ruben Skyum <lars.skyum@stibo.com>
<UL>
<LI> VisualMagick/bin/modules.mgk: added EPS3 mapping to PS3 module.
<LI> 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.
</UL>
<p>
2003-10-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> coders/cineon.c: Imported and adapted Cineon image format coder
written by Kelly Bergougnoux <three3@users.sourceforge.net> with
assistance from John Cristy.
</UL>
<p>
2003-10-08 Glenn Randers-Pehrson <randeg@alum.rpi.edu>
<UL>
<LI> coders/jpeg.c: Extended -sampling-factor option to allow

deep gray images since the TIFF spec says that LZW compression is
usually improved by using horizontal differencing with continuous

<LI> 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.
<LI> magick/attribute.c: Added TracePSClippingPath for creating a
postscript clipping path from a photoshop clipping path.
<LI> 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.
<LI> magick/image.c: ClipPathImage now stores the name of the
clipping path in the mask image filename so that it is remembered

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.

<LI> 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 *.<BR>
(lt_dlsym): lt_dlsym is supposed to take a const char *.
<LI> magick/nt_base.h: lt_dlclose should return an 'int'.
<LI> magick/nt_base.c (lt_dlclose): Return status from lt_dlclose.
<LI> magick/module.c (lt_dlclose): lt_dlclose is supposed to return
an 'int', not 'void'. A return value of zero indicates success.
<LI> VisualMagick/tests/run_constitute.bat: Add batch script to

<LI> magick/module.c (UnloadModule): Report exception via exception
parameter rather than simply printing out an error message and
exiting.<BR>
<LI> magick/Makefile.am (noinst_HEADERS): integral_types.h had to be

via Makefile.am rather than configure.
<LI> magick/magick_config_api.h.in: Added template header for
the installed magick_config.h.<BR>
<LI> 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.
<LI> configure.ac: Added tests for sigemptyset and
sigaction.<BR>

<LI> 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

<LI> utilities/Makefile.am (check): Added code to put logo on demo

<LI> magick/command.c (MontageImageCommand): Pass exception rather

pointless to store the exception where it will not be reported to
the user anyway.<BR>
<LI> utilities/Makefile.am (check): Ported Glenn Randers-Pehrson's
utilities demo script into the Makefile to serve as a check
target.<BR>

<LI> magick/magick.c (InitializeMagick): Decided to
move clean-up signal-handler registration from gm.c

if a user program wants to do something special for
signals registered to be caught by InitializeMagick
<STRONG>(SIGHUP, SIGINT, SIGQUIT, SIGABRT, SIGTERM, SIGXCPU,</STRONG>

own signal handlers after invoking InitializeMagick.
The user is then responsible for making sure that
DestroyMagick is invoked if an unexpected signal is

determine total physical memory for Darwin.
<LI> magick/delegate.c (ListDelegateInfo): If COLUMNS

CVS as delegates/freetype2 rather than delegates/ttf
so be sure to re-checkout the ttf directory so that
the correct files are used.<BR>
<LI> 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

FreeBSD 5.0.<BR>
<LI> magick/deprecate.c (ValidateColormapIndex): Remove
non-interface deprecated function.
<LI> magick/tempfile.c (AcquireTemporaryFileDescriptor):
Priortize use of mkstemp() over tempname() since *BSD

tempname() safely).<BR>
<LI> magick/color.c (ConstrainColormapIndex): Removed
function since it is no longer used.
<LI> magick/utility.c (TemporaryFilename): Removed

<LI> magick/studio.h: Don't define _ISOC99_SOURCE,

<LI> 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.<BR>
(EqualizeImage): Only equalize the opacity channel if
image->matte is true. This results in a 23% speedup.
