This release fixes many bugs, adds many improvements, and adds new major features. Quite a few volunteers contributed to this release. The following are the major changes since the 1.3.5 release: Security Fixes: * None. Bug fixes: * Composition was failing when the change image overlaps off the left side of the canvas. * EPT, PDF, PS: PDF bounding box is sometimes incorrect or not globally applicable so don't specify bounding box when reading PDF files. * OpenMP: Fix (benign) multi-thread cross-contentions (detected by valgrind's Helgrind). * TIFF: Fix problem with reading one bit per sample RGB images. * TIFF: Writer was using rows-per-strip of 8 when writing JPEG-compressed TIFF. This does not work for vertical subsampling, and some TIFF readers insist on 16. The rows-per-strip is now required to be a multiple of 16. * TIFF: In some cases, the TIFF reader and writer were accessing planar TIFF in row-order rather than plane-order, which resulted in sever buffering problems in libtiff, and failure when compression was used. * -write now works usefully as documented. * Temporary file name generator was not random enough, resulting in some file name collisions for GraphicsMagick processes started at the same time. * PerlMagick: Fixed Ping on a BLOB. * GetImageDepth was leaking memory. * Convert/mogrify -mask option was leaking memory. * Mogrify -output-directory option was leaking memory. * DPX: Fixed memory leak encountered when subsampling to 4:2:2. * DPX: Values read received insuficient scaling, which round-tripped correctly, but rounded-down excessively if any image processing was applied. New Features: * Added HRS reader for slow scan TV (contributed by Fojtik Jaroslav). * Pthreads (POSIX threads) API may now be used under the WIN32 API. * New access confirmation facility (MagickConfirmAccess) to allow the API user to monitor and/or block access to files and URLs. This allows the API user to implement a security policy based on actual accesses. * New color matrix function (ColorMatrixImage) to apply a color matrix similar to Adobe Flash Flash.filters.colorMatrixFilter(), and Windows GDI+ ColorMatrix class, (order up to 5x5) to the image pixels. This is accessible via the -recolor command option. * Added an IDENTITY coder to return a Hald identity CLUT image of specified order (e.g. "identity:8"). * Added a Hald CLUT capability as described at http://www.quelsolaar.com/technology/clut.html. This allows a color transformation to be easily created and replicated on any number of images. The algorithm is accessed by the -hald-clut option of 'convert' and 'mogrify'. Original algorithm by Eskil Steenberg and adapted for GraphicsMagick by Cl?ment Follet, with additional work by Bob Friesenhahn. * Added support for the ASC CDL transform. Available as -asc-cdl via the 'convert' and 'mogrify' subcommands. Original implementation by Cl?ment Follet but considerably re-worked by Bob Friesenhahn. Implementation passes the +/- 1 count accuracy requirement required by the ASC CDL SOP tests. * Added support for reading CALS Type 1 format (contributed by John Sergeant). CALS is a standard raster format used by the US Department of Defense for storing blueprint images. * Added a random number generation system based on George Marsaglia's multiply-with-carry generator. Somewhat slower than rand() but produces better random numbers with a period >2^60. This is a much better random number generator than the C library rand() and the algorithm is integrated in a way which maximizes multi-thread performance. * The 'compare' command now supports a -maximum-error option to specify the maximum image error so that it may be used to support boolean logic in automated test scripts. * For OpenMP-builds, the '-list resource' output now indicates the number of threads which will be used. Feature improvements: * Image resize now avoids adding "halos" around objects when resizing an image which contains transparency (patch contributed by Pavel Merdin). * DICOM: The DICOM reader is completely re-written and is much more functional now. A few features (e.g. RLE compression) are still missing. This work is contributed by John Sergeant. * EXIF: Unprintable characters in EXIF attribute strings are now returned using three-digit octal notation. Unknown tags are identified via their four-character hex value. * PCL: PCL writer is rewritten to fix many bugs, add support for compression, add support for 8 bit PseudoClass images, and dramatically improve usability (work contributed by John Sergeant). * TIFF: Allow the user to force the returned image to be TrueColor type for min-is-white and min-is-black TIFF files. * TIFF: User can now specify the predictor using syntax like '-define tiff:predictor=2'. * TIFF: User can now specify the rows-per-strip value when using JPEG compression. * TXT: The TXT reader is now capable of reading image files written by the TXT writer, as well continuing to render ASCII text into an image (work contributed by Fojtik Jaroslav). * Utilities @file.txt syntax for including a list of files to use as an argument now really works as expected. This may be used to inject any other text into the command line as well. As a result, the 'mogrify' utility may be invoked on thousands of files at once while obtaining the list of files to process from a text file. * The 'mogrify' utility now caches argument images so that they are loaded only once when mogrify is used to process multiple image files. Performance Improvements: * -median and -noise now see reliable linear speedup as threads are added. Behavior Changes: * PerlMagick is configured but no longer built by default. * Use '-interlace Line' to produce an interlaced GIF, PNG, or progressive JPEG.
