Changes since version 5.5.6:
- File descriptor leak prevented temporary disk pixel cache from being
removed under Windows.
- Color profile patches provided by (dge at softec.st).
- West/East geometry was computed with image width rather than height.
- The MNG encoder failed to set the JNG bit in the simplicity profile.
- The MNG encoder failed to write FRAM chunks when all images were JNG.
- The JNG encoder wrote the wrong alpha_sample_depth for opaque images.
- Fixed JPEG EXIF problem.
- Added -thumbnail as an option to the utilities.
- No TIFF preview was written on EPT write (patch provided by
Lars Ruben Skyum).
- NegateImage() now negates the K channel of a CMYK image (patch provided
by Lars Ruben Skyum).
- Parameter 'elevation' misspeclled for PerlMagick Shape() method.
- A number of minor leak/unitialzed memory problems fixed.
- Allocate free nodes from the heap in QuantizeImage().
- Magick-config --version returned gibberish.
- Adopted Bob Friesenhahn's patterns-- use as filename pattern:checkboard,
pattern:bricks, etc.
- We cannot reliably auto rotate PDF files so this feature was removed.
- The conjure program did not correctly handle the gravity attribute.
- The persistent cache reference count was not properly incremented.
- Added $image->Describe() method to PerlMagick to interface to the
DescribeImage() C API method.
- Added support for the EXIF Tag Parsing Library. Currently we simply
display the tags when calling DescribeImage(). In the near future
there will be support for modifying or adding tags.
- Added Bob Friesenhahn's updated Windows installation instructions.
- Interfaced the drawing routines with the new MagickWand API.
MagickWand will be the primary public C interface to ImageMagick in
the near future.
- magick/effect.c: RandomChannelThresholdImage was not handling
PseudoColor, non-gray images correctly.
- png.c would not compile with libpng versions older than libpng-0.95,
due to bugs introduced in ImageMagick version 5.5.2.
- Implemented -random-threshold and -ordered-dither options.
- The locale messaging system now uses a hash for fast lookup.
- Updated libtool to the new released version, 1.5.
- Fixed bug with decoding grayscale PNG images and JNG alpha channel
at Q:32.
- Now recognize 32-bit hex color specifications, patches provided by
Bob Friesenhahn.
- Started API wrappers based on Bob Friesenhahn's method suggestions.
- Text annotations that started with '\n' were not rendered correctly.
- Removed artifacts from images rotated with a small number of degrees.
- Minor bug fix in the ParseGeometry() method.
- Modified the non-public inline AlphaComposite() to use a PixelPacket
pointer; previously it returned a PixelPacket structure.
- You can now specify an image geometry as an image file (e.g. -geometry
image.jpg).
- Use new temporary file manager for JNG components.
- Added support for 12-bit TIFF images.
- Added improved locale message subsystem (contributed by Kyle Shorter).
- Removed a bias from SampleImage() and DrawAffineImage() (bug report
by Glenn Randers-Pehrson).
- PerlMagick now recognizes percent values for fuzz or opacity.
- Not enough memory allocated for reading PCX (bug report by Trevor
Willis).
- There were artifacts when using the Bessel function for resizing
(bug report by Bob Friesenhahn).
- Added -resample to convert to change the resolution of an image.
- Added a temporary file manager that prevents race conditions and
removes any remaining files on exit.
- Prepped ImageMagick to work with Visual C++ 7.0 under Windows.
The Windows configure patches came from William Radcliffe.
- The refresh of the display image window no longer lags when the
magnify window overlay it.
- Numerous code clean-up and minor speed ups based on problem areas
identified in the Graphics-Magick ChangeLog.
