# GraphicsMagick ChangeLog - 2002

2002-12-31 Cristy <cristy@mystic.es.dupont.com>

> - magick/command.c: Do not quantize CMYK (bug fix).

> - magick/render.c: Ensure that stroke is not drawn wider than 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.

2002-12-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/image.c: Optimized gray x, y, z, tables creation in RGBTransformImage().

2002-12-27 Cristy <cristy@mystic.es.dupont.com>

> - coders/pcd.c: IsPCDImage() fix offset to test header magic.

> - coders/pcd.c: Ensure that blob is closed on error.

> - coders (all): Pass image->colorspace to TransformRGBImage()

> - magick (animate.c, command.c, display.c, image.c, nt_feature.c) Pass image->colorspace to TransformRGBImage().

> - 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.

> - coders/bmp.c: Updated to use VerifyColormapIndex macro.

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.

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

> - magick/resize.c: Use type double rather than long for minify weighting constants.

2002-12-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/image.h: AdaptiveThresholdImage offset must be 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. This makes the tests easier to maintain and also makes it easier to find errors in ImageMagick.

2002-12-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c: Warnings reduction

> - magick/list.c: Warnings reduction

2002-12-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Updated PerlMagick tests for Emboss, Equalize, Gamma, Normalize, OilPaint, and Gradient so that they pass at Q:8 under Windows.

> - Updated PerlMagick tests for Emboss, and reading WMF, so that they pass at Q:16 under Windows.

> - VisualMagickinstallerImageMagick-16.iss: Ported over from ImageMagick-8.iss and verified.

2002-12-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Major smashing of ImageMagick to GraphicsMagick in .txt files and .html files.

> - ImageMagick.html: Renamed to index.html.

> - www/ImageMagick.html: Renamed to www/GraphicsMagick.html

2002-12-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/list.c: Added GetFirstImageInList() function.

> - magick/list.c: Added GetLastImageInList() function.

> - coders/pcd.c: Re-implemented image tile labeling to avoid use of MogrifyImages().

2002-12-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Added commit shell script to CVS for those who chose to use it.

2002-12-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/magick.c: Ensure that operating system call error 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 allows users to add their own modules without requiring the use of a special "modules" build.

2002-12-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/image.h: Backed out arbitrary name change from ChannelThresholdImage() to ThresholdImageChannel() that snuck in from Cristy's image.h changes.

2002-12-11 Cristy <cristy@mystic.es.dupont.com>

> - coders/psd.c: Reference cloned image Blob (not sure why needed but must be important).

2002-12-11 Cristy <cristy@mystic.es.dupont.com>

> - magick/enhance.c: Fixed LevelImage() to accept percent black/white points (.i.e. 90%).

> - magick/enhance.c: Added LevelImageChannel().

> - magick/enhance.c: Improved Q:8 performance of color transformations (e.g. for Gamma) which are based on a mapping array.

> - coders/pcl.c: Fixed PCL coder to output proper color PCL instructions.

2002-12-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/image.c: Disabled SetImageInfo() code which uses 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 provides a back door way for the COM object to have data read or written into VB arrays.

2002-12-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/mac.c: Merged in fixes from ImageMagick version.

> - magick/magick.mgk: Merged in fixes from ImageMagick version.

2002-12-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/image.c: Fix ChannelImage() so that it does not destroy CMYK(A) channels by forcing RGB.

2002-12-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/version.h: Changed to release 1.0.0.

> - magick/nt_base.c: Changed "ImageMagick" to "GraphicsMagick" so registry lookups work for GraphicsMagick. Probably should be configured via a magick_config.h define.

> - VisualMagick/installer/ImageMagick-8.iss: Changed for GraphicsMagick.

> - utilities/conjure.c: Fix unterminated comment.

2002-12-06 William Radcliffe <billr@corbis.com>

> - coders/jpeg.c: Modification of JPEG APP1 detection logic to name EXIF and XMP profiles as EXIF and XMP instead of APP1. THe current algorithm is brute force.

> - coders/meta.c: Modification deal with EXIF and XMP requests so that you can ask for these blobs specifically if they exist.

> - coders/pdf.c,ps.c,ps2.c,ps3.c: Cristy bug fixes to eliminate redundant file access checking and fix embedded JPEG support.

> - magick/random.c: Upgraded this to match current Cristy code. The upgrade is to support more robust temporary filenames in another change to this in utility.c however, I have not upgraded this code yet because I don't understand it well enough.

2002-12-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Added build support for utilities/gm.c

2002-12-06 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

> - Relocated animate, conjure, display, and import functions into command.c.

> - Added utilities/gm.c; gm is a driver for all of the utility functions (animate, composite, conjure, convert, display, identify, import, mongrify, and montage), which are now run with "gm convert [convert_options]", "gm identify [identify_options]", etc.

2002-12-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/pdf.c: Remove bogus code for handling temporary file.

> - Removed defunct HDF and libmpeg2 support since it was 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. This improves the output when the WMF is rendered on a non-default background.

2002-11-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2002-10-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/xwindow.c: Optimize loading of TrueColor images with gamma = 1.0.

2002-10-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/wmf.c: Added logging facilities.

2002-10-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - display.c: removed unnecessary SignatureImage() calls which dramatically slowed down loading images and quiting the program.

> - xwindow.c: optimized image size reduction for the case where the target size is a small fraction of the original size. This makes creation of display's panner and thumbnail images tremendously faster, with no noticeable degradation of thumbnail quality.

2002-10-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Added Windows95 define to VisualMagick magick_config.h to disable use of features not available under Windows '95

2002-09-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Update to Autoconf 2.54.

2002-08-08 Cristy <cristy@mystic.es.dupont.com>

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. "\").

2002-05-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
