2003-11-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/draw.c (DrawComposite): Base64 encoded image was not being deallocated. Bad memory leak.

2003-10-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- configure.ac: Updated to use GNU Automake 1.7.8 and the very latest CVS libtool.

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 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- coders/png.c (ReadOnePNGImage): PNG decoder would exit too early when reading image.png[0].

2003-10-04 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- Revised ScaleColor5to8 and ScaleColor6to8 macros to fill in the low bytes.
- coders/bmp.c (ReadBMPImage): scaling of 5-5-5-bit, 5-6-5-bit and 8-8-8-8-bit images was slightly incorrect.

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.

2003-09-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/render.c (DrawClipPath): Fix memory leak of clone_info->clip_path. Problem reported by Vladimir <lvm@integrum.ru>.

2003-08-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- 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.

2003-08-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/blob.c (BlobToImage): Skip calling SetImageInfo() if magick is already set.

2003-08-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2003-07-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- NEWS: Updated to include current changes since 1.0.2.

2003-07-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/semaphore.c (UnlockSemaphoreInfo): Bugfix, modify the 'locked' flag while still under protection of the lock. This fix is necessary for thread-safety.

- INSTALL-unix.txt: Add additional information regarding LZW.

2003-06-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/bmp.c (ReadBMPImage): Only validate the file size value for compressed BMPs.

2003-06-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- version.sh: Update to unreleased 1.0.3 so that development builds from CVS do not interfere with existing 1.0.2 release library.
- configure.ac: Don't add -lfpx to LIBS while configuring because the C compiler may fail to link with it in later tests.

2003-06-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- GraphicsMagick 1.0.2 released.
- magick/command.c (ConvertImageCommand): Eliminate warnings noticed with Sun compiler.
- acinclude.m4: Add '#undef inline' in front of C++ tests.
- coders/x.c (RegisterXImage): Only register the X coder if HasX11 is defined.
- libxml/libxml2.def: Since VisualMagick configure is not fixed yet, add "LIBRARY CORE_RL_libxml_.dll" to the top of the file to at least cover the release build case.

2003-06-07 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- magick/image.c (GetImageGeometry) Y was a function of width instead of height when processing EastGravity or WestGravity (bug report from Cristy).

2003-06-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/log.c (ReadConfigureFile): Move event parsing to ParseEvents funtion.
  (SetLogEventMask): Move event parsing to ParseEvents funtion.
- 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.
- magick/utility.c (GetGeometry): Validate that the geometry string only contains valid characters.
- Magick++: Updates to cause exceptions to be thrown if a bad geometry specification is supplied.

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.

2003-06-02 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- png.c: Merge bugfixes from 1.1 branch:
- MNG encoder failed to set the JNG bit in the simplicity profile.
- MNG encoder failed to write FRAM chunks when all images were JNG.
- JNG encoder wrote the wrong alpha_sample_depth for opaque images.
- coders/png.c: png.c would dump core when writing a grayscale image in png24 or png32 format.

2003-06-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/version.h.in: Change to be Copyright (C) 2002, 2003.
- NEWS: Updated to incorporate changes since the 1.0 release.
- version.sh: Bump library revision and release version since code updates have been made.
- libxml/libxml2.def: Remove 'LIBRARY libxml2' statement which confuses Visual C++ 6.0.

2003-05-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/viff.c (RegisterVIFFImage): Module definition for "XV" was missing.

- coders/html.c (RegisterHTMLImage): Module definition for "HTML" was missing.
- coders/bmp.c (RegisterBMPImage): Module names for "BMP2" and "BMP3" should be "BMP".

2003-05-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/command.c (MogrifyImageCommand): Wrong exception macro was being invoked. Steps have been taken to ensure that this doesn't happen again.
  (ImportUsage): Fix spelling of 'type'.

2003-05-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/ept.c (WriteEPTImage): Fixed writing EPT preview image and added logging.
- PerlMagick/Magick.xs: Fix spelling of 'elevation' argument to Shade method.
- 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.
- magick/GraphicsMagick-config.in: Added example usage to the help output.
- magick/type.c (GetTypeBlob): Search $MAGICK_HOME for type.mgk.
- 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/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.

2003-05-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- GraphicsMagick 1.0.1 released.
- version.sh (PACKAGE_RELEASE_DATE): Update for 1.0.1 release.
- index.html: Adjust width setting for magick.png.
- coders/logo.c: Update to use temporary frog logo image until official logo image is available.
- magick/magick_config_api.h.in: Add HasX11 so installed xwindow.h works.
- images: Replace logo images with temporary frog logo image.

2003-05-17 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- coders/png.c: stifled compiler warnings about uninitialized chunk and blob variables.

2003-05-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- version.sh (CHANGE_DATE): Update to reliable awk-based technique to extract the latest change date from the ChangeLog file.
- Makefile.am (EXTRA_DIST): QuickStart.txt and QuickStart.html have not been updated, and are misleading, so they are removed.

2003-05-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/msl.c (MSLStartElement): Don't reset gravity if the user provides an x,y coordinate. Passing coodinates was loosing the gravity setting.

2003-05-05 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.

2003-04-30 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- 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: 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.

  (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.

- 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

- 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.

- libtool: Update to latest CVS version.
- configure.ac: Test zlib for gzseek and gztell.
- magick/effect.c (ChannelThresholdImage): The is_grayscale flag was not be evaluated correctly.

2003-03-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.h (RoundSignedToQuantum): Added handy RoundSignedToQuantum macro for munging doubles into Quantums.
- magick/effect.c (ThresholdImage): Added optimizations for thresholding all pixels to white or black. Threshold using an integral value rather than a double so compares are faster. (ChannelThresholdImage): Threshold against integral values since compares are faster. Invoke ThresholdImage for simple thresholding across all channels since it is faster.

2003-03-19 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- coders/meta.c: #ifdef'ed out some dead code.
- magick/annotate.c: #ifdef'ed out some code that is only used when HasTTF is defined.
- Added RandomThresholdImage() method and -random-threshold commandline option.

2003-03-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/cache.c (SyncCacheNexus): Add back in is_monochrome and is_grayscale flag resetting which was lost by copying over ImageMagick's cache.c.
  (FilePositionRead): Inline wrapper for reading a chunk of data at an offset.
  Cleans up some messy code, and makes it easy to use pread(). (FilePositionWrite): Inline wrapper for writing a chunk of data at an offset.
  Cleans up some messy code, and makes it easy to use pwrite(). Cache now uses pread() and pwrite() to access the cache if these calls are available.
- magick/resource.c (InitializeMagickResources): Support setting resource limits via the environment variables MAGICK_LIMIT_DISK, MAGICK_LIMIT_FILES, MAGICK_LIMIT_MEMORY, and MAGICK_LIMIT_MAP.

2003-03-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/cache.c: Snarfed cache.c updates from ImageMagick.
- magick/command.c: Added -list resource support.

2003-03-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2003-03-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- Makefile.am (DIST_SUBDIRS): Filters subdirectory needs to be distributed.

2003-03-14 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- magick/render.c Ported Cristy's bugfix to DrawAffineImage().

2003-03-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.c (DestroyImage): Comment out new assertions until we are certain that there are no ill effects.
- coders/mat.c (ReadMATImage): Set image->depth to valid values.
- PerlMagick/Magick.xs: Update so that new DestroyImage assertions aren't asserted.
- magick/list.c (DestroyImageList): Update so that new DestroyImage assertions aren't asserted.
- coders/wpg.c (ReadWPGImage): Don't leave dangling pointer when trimming list. Don't set image->depth to invalid values.

2003-03-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.c (DestroyImage): Add assertions to verify that destroyed image is not currently referenced by another image. This should help prevent accidental continued use of a destroyed image.
  (DestroyImage): Added assertions to enforce that images should not continue to reference the destroyed image.
- coders/wpg.c: Incorporated fixes from Jaroslav Fojtik.
- version.sh (PACKAGE_VERSION_ADDENDUM): Construct a package snapshot version based on the ChangeLog modification time. This requires GNU find to work propery since the -printf option is used.
- configure.ac (LIB_GS): Do not test for the Ghostscript library by default due to the issue of its embedded libjpeg conflicting with libjpeg.
- coders/ept.c (ReadEPTImage): "PostscriptDelegateFailed" should be classified as a DelegateError type.

2003-03-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/blob.c (BlobToFile): Truncate while opening file. (ImageToFile): Truncate while opening file.
- magick/annotate.c (RenderFreetype): Missing freetype library should result in a MissingDelegateError type rather than a DelegateError type.
- INSTALL-windows.txt: Added a note regarding a workaround for internal compiler errors while compiling image.c when using Visual C++ 7.0.
- coders/jpeg.c (ReadICCProfile): Incorporate ImageMagick fix to handle short JPEG ICC profiles.
- magick/integral_types.h: Ignore SIZEOF_LONG_LONG and SIZEOF_UNSIGNED_LONG_LONG defines if _VISUALC_ is defined.

2003-03-11 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- www/gm.html, utilities/gm.1, guide/gm.tex: Expanded description of the -affine option.

2003-03-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/image.c (GetImageDepth): Re-implemented using a single-pass algorithm and 1/2 the code. Previous implementation didn't return correct results for Q:32 build. Now it does.
- magick/command.c (IdentifyImageCommand): For identify, when %q format specifier is present, image must be read rather than pinged. If not, either the value 8 is returned, or there is a crash due to reading an uninitialized image.

2003-03-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/mat.c: Incorporate fixes from Jaroslav Fojtik. Close Blob before rotating image.

- www/gm.html, utilities/gm.1, guide/gm.tex: First cut at manpage for gm, to replace individual utility manpages.

2003-03-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- magick/blob.c: Fix some erroneous log printf specifications. Improved blob log messages a bit.
- magick/log.c (IsEventLogging): Use InitializeLogInfo(). (InitializeLogInfo): New function to intelligently initialize logging subsystem. Only locks when initialization may be required, and only locks long enough to determine if initialization is required. 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 BLOB I/O so don't use OpenBlob/CloseBlob. Opening the blob caused a conflict when the FlashPIX library attempted to open the file.

2003-03-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- configure.ac: Test for libtiff functions (TIFFClientOpen & TIFFIsByteSwapped), which are required by GraphicsMagick, but not found in older libtiff versions.
- magick/blob.c: Added logging for Blob open/close and memory mapping operations.

2003-03-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- tests/rwblob.c (main): DestroyImage asserts on NULL so only call it for non-null image.
- tests/rwfile.c (main): DestroyImage asserts on NULL so only call it for non-null image.

- magick/cache.c (SyncCacheNexus): If image pixels are updated then set image is_grayscale and is_monochrome members to False. Algorithms which want to preserve the values of these members 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.
- magick/constitute.c (ReadImage): If the returned image is PseudoClass then invoke IsGrayImage() and IsMonochromeImage() and cache the result in image is_grayscale and is_monochrome members for later use.
- magick/image.h (Image): Added is_grayscale and is_monochrome members to remember if image is grayscale or monochrome.

2003-02-14 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

  (WriteBMPImage): Convert PseudoClass images with more than 256 colors to DirectClass.
  (WriteBMPImage): Do not require 2-color images to pass the IsMonochromeImage() test before writing them as one-bit-per-pixel BMPs. Decided to allow this after four readers (including Windows XP) displayed the image using the proper colormap. (WriteBMPImage): BMP2 encoder was writing colormap using wrong format.
- images: Updated logo images to GraphicsMagick
- Added PDF Sages to web page as a sponsor.

2002-02-08 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

- 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.

- 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.

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.

- 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.
- magick/enhance.c: Tweaks to equalization map calculation to (hopefully) provide more consistent results.

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 allows users to add their own modules without requiring the use of a special "modules" build.
