2008-12-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - VisualMagick/installer/inc/body.isx: They say that when in Rome you should do as the Roman's do. Based on this philosophy, all of the coder and filter DLLs are now installed to the same directory as the executables and DLLs which depend on them. This eases operation under Windows Vista.

2008-12-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/blob.c: First pass at supporting large file access under Windows.

2008-12-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (MogrifyImage): The -write option was not implemented in a useful fashion and the +write option never worked at all. Re-implement -write and eliminate +write from the documentation since +write is not needed.

2008-12-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/tiff.c (ReadTIFFImage, WriteTIFFImage) Support reading and writing 64-bit integer TIFF.

> - coders/tiff.c (ReadTIFFImage): Fix bug with ping mode.

2008-12-07 Fojtik Jaroslav <JaFojtik@seznam.cz>

> - coders/fits.c: Proper signed to unsigned conversion for 64 bit LSB images.

2008-12-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/Makefile.am: When X11 is disabled, don't compile the X11-specific source modules. Don't ever install any X11-related header files.

2008-12-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/segment.c (SegmentImage): Use double rather than 64-bit integer to accumulate totalized values. Make the cluster summary report more concise.

2008-12-06 Fojtik Jaroslav <JaFojtik@seznam.cz>

> - coders/fits.c: Fix for 64 bit images.

2008-12-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/segment.c (SegmentImage): Cluster threshold is expressed as a percentage of total cluster pixels. Optimize for larger images.

2008-12-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/segment.c (SegmentImage): Accelerate using OpenMP.

2008-11-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/utility.c (TranslateTextEx): Support formatting huge comment text.

2008-11-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/fx.c (ConvolveImage): Don`t process opacity channel unless image has one.
> - magick/effect.c (MotionBlurImage): Use AcquireOnePixelByReference() rather than AcquireImagePixels() to retrieve one pixel. This is much more efficient. (AdaptiveThresholdImage): Don`t process opacity channel unless image has one. (BlurImage): Don`t process opacity channel unless image has one.

2008-11-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/profile.c (ProfileImage): +profile now supports a simple exclusion syntax. For example, to strip all of the profiles except for the ICM profile use +profile '!icm,*'. The new syntax also allows multiple profile names to be listed at once. The primary requirement is that all excluded profiles must be listed prior to those to be stripped.

2008-11-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/transform.c (RollImage): Remove image storage class alteration. (CompositeImageRegion): Ensure that the canvas image storage class is correct.

2008-11-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - config/delegates.mgk.in: Since we removed support for spawn a long time ago, and no longer execute using the Unix shell by default, we need to add an ampersand to the end of the two entries previously using spawn so that the display program does not hang when it invokes the external program.
> - utilities/Makefile.am (UTILITIES_TESTS): Add preview-based tests.
> - coders/preview.c (WritePreviewImage): Solarize requires a threshold argument.
> - coders/vid.c (WriteVIDImage): Eliminate memory leak.
> - magick/montage.c (MontageImages): Fix continued use of freed memory.

2008-11-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - utilities/tests/msl_composite.sh: Fix rm -f without a valid argument which annoyed NetBSD.
> - coders/fits.c: Impose a limit on the length of the row PDU. Make sure that GraphicsMagick version information does not overflow the length allowed by a row PDU.

2008-11-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/jpeg.c (WriteJPEGImage): Use DCT algorithm default from the library rather than the header file.
> - magick: Adjust OpenMP scheduling options based on observed behavior.

2008-11-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/shear.c (IntegralRotateImage): Added OpenMP acceleration for rotate by 90 and 270 degrees.
> - configure.ac: New --disable-openmp-slow configure for disabling use of OpenMP for algorithms which may run slower on operating systems with crummy thread libraries. This still allows gaining the benefits from OpenMP for CPU hogs. Verified to help with FreeBSD 7.0 and Apple OS-X Leopard.
> - magick/semaphore.c: Trimmed out the debug code in order to obtain a bit more performance.

2008-11-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/jpeg.c: Allow the user to specify the DCT method (jpeg:dct-method), or if huffman encoding should be enabled (jpeg:optimize-coding=true). Default the DCT method to the libjpeg default rather than forcing it to JDCT_FLOAT since float is slower on some systems.

2008-11-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/jp2.c (BlobClose): Leak a little bit less memory when reading a JP2 file.

2008-11-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - wand/wandtest.c: Eliminate memory leak.

> - magick/enhance.c (ModulateImage): Improve progress message.
> - coders/msl.c: Eliminate memory leaks.
> - GraphicsMagick.spec.in: Apply RPM spec file fixes from Giacomo Tenaglia for Red Hat Linux 4.

2008-11-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/msl.c: Fix bug with attributes becoming appended to themselves. Resolves SF issue 2255754. Reflowed code.

2008-11-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - version.sh: GraphicsMagick 1.3 released. Next release on head will be 1.4.
> - www/OpenMP.rst: Updated with latest measurement data.
> - www/benchmarks.rst: Updated with latest benchmark data.
> - coders/url.c (RegisterURLImage): Register HTTP and FTP URL support in the "unstable" category since these are capable of accessing the network and therefore represent a potential security issue. Register the FILE URL support in the "stable" category since it is capable of incorporating local disk files, which may still represent a security security issue for server applications. Note that disabling these functions might cause some existing MSL, MVG and SVG scripts to stop working if they use external URLs.

2008-11-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/pnm.c (ReadPNMImage): Sequential multi-thread the PNM raw format readers. Can improve read performance quite substantially for large PBM and PGM files, and less so for PPM. There is most benefit for systems with more I/O than one CPU core will support. Systems with slow I/O and a relatively fast CPU may see somewhat diminished read performance with more CPU consumption. As such, this is effectively a verification that multi-threading the reader is possible, and may be of benefit to power-users.
> - magick/omp_data_view.c (AllocateThreadViewDataArray): New function to allocate a thread view data array. Updated modules using similar code to use this function in order eliminate useless redundancy.

2008-11-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/pixel_cache.c: Incorporate OMP thread views into the pixel cache so usage is less invasive. Update OMP-enhanced source modules to suit. (GetImagePixelsEx): New function similar to GetImagePixels() except that it reports exceptions to a user-provided structure. (SetImagePixelsEx): New function similar to SetImagePixels() except that it reports exceptions to a user-provided structure. (SyncImagePixelsEx): New function similar to SyncImagePixels() except that it reports exceptions to a user-provided structure. (AccessImmutableIndexes): New function to access read-only colormap indexes. (AccessMutableIndexes): New function to access writeable colormap indexes. (AccessMutablePixels): New function to access writeable pixels. (AccessDefaultCacheView): New function to access the default cache view.

2008-11-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (BenchmarkImageCommand): With no other arguments, the benchmark command now defaults to one iteration.
> - magick/effect.c (SpreadImage): Offsets array size is a prime number to help avoid beating. (SpreadImage): Ensure that spread loops are always terminal.
> - magick/utility.c (MagickRandReentrant): Fix bug where rand() was being continually re-seeded if rand_r() was not available.

2008-11-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - utilities/tests/msl_composite.sh: Replace SVG image generation with simpler approach which properly centers the text. Use our own font so that tests will pass if the user does not have fonts installed.
> - magick/utility.c (GetMagickDimension): Extend to support parsing optional x and y offset values and use to fix parsing for -oil-paint and -unsharp when sscanf() is C'99 compliant.

2008-11-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/pixel_cache.h (AcquireOneCacheViewPixel): Pass pixel to update by reference. (AcquireOnePixelByReference): New private inline method which passes pixel to update by reference.
> - magick/omp_thread_view.h (AcquireOneThreadViewPixel): Pass pixel to update by reference.
> - magick/alpha_composite.h (BlendCompositePixel): Replace BlendComposite with BlendCompositePixel, which passes the composite pixel by reference. (AlphaCompositePixel): Replace AlphaComposite with AlphaCompositePixel, which passes the composite pixel by reference. (AtopCompositePixel): Replace AtopComposite with AtopCompositePixel, which passes the composite pixel by reference.
> - configure.ac: With excessive maintenance releases, the library age portion of MAGICK_LIB_VERSION was overflowing its allotted space. This resulted in 1.1.X releases reporting the wrong MagickLibVersion as of 1.1.10. Fix this by supporting up to 99 values for each field.

2008-11-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac: Fix passing the --with-windows-font-dir option via DISTCHECK_CONFIG_FLAGS.
> - utilities/tests/msl_composite.sh: Integrated MSL composition test script contributed by Max Hohenegger, Max at hohenegger.eu.
> - magick/command.c (ConjureImageCommand): Return status was inverted so one was returned for command success rather than zero.

2008-11-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - png: Updated libpng to 1.2.33 release.
> - magick/color.c (FuzzyColorMatch): If fuzz is zero then completely use the result of ColorMatch() rather than entering unnecessary expensive code.

2008-10-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/studio.h: Make sure we don't conflict with OpenMP implementation if it is active but we are not using it.

2008-10-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/studio.h (HAVE_OPENMP): Add logic to make sure that OpenMP is only engaged for OpenMP 2.0 or later.
> - magick/command.c (VersionCommand): Report OpenMP version.
> - Makefile.am: The Magick++ build was supposed to be optional. Now it is.
> - Makefile.am: Eliminated .tar.bz2 and .zip packages from the distribution. The .tar.bz2 package was hardly smaller than the .tar.gz package so it wasted 5.9MB with little benefit. The compression ratio on the .zip archives is absolutely terrible so eliminating zip eliminates huge 9.6MB and 25MB files from the distribution equation. Windows users can easily learn how to use the vastly more efficient 7-Zip format.

2008-10-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac: Rationalize OpenMP tests to make sure that OpenMP can not be enabled without thread support.

2008-10-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/composite.c (CompositeImageRegion): Add some minimal region limit checking. Not completed yet.

> - magick/omp_thread_view.h (AccessThreadView): Inline function for a bit more performance. (AcquireOneThreadViewPixel) Inline function for a bit more performance.

2008-10-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - pragma omp parallel for: Use consistent static scheduling throughout and ensure that 64 threads can be usefully engaged on a 1024 row image.
> - magick/pixel_iterator.c (SetRegionThreads): Implement logic so that pixel iterators execute single-threaded when invoked on tiny regions.
> - magick/pixel_cache.c (SetNexus): Make staging buffer memset() conditional in order to dramatically diminish impact to small accesses. This memset() only exists to make valgrind happy.

2008-10-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2008-10-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/pixel_cache.c (GetCacheViewRegion): New function to return the region bounded by a pixel cache view.
> - magick/constitute.c (ExportViewPixelArea): New function to support exporting the pixels from a pixel cache view. (ImportViewPixelArea): New function to support importing pixels to a pixel cache view.

> - coders/xtrn.c (ReadXTRNImage): XTRNSTREAM mode was never implemented so remove unfinished stub code.

2008-10-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/image.c (SetImageDepth): Needed to assign image depth attribute to user-specified depth rather than only altering the pixels. (SetImageOpacity): Reimplement using pixel iterators. (AverageImages): Accelerate using OpenMP. (GetImageBoundingBox): Accelerate using OpenMP.

2008-10-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/constitute.c (ConstituteTextureImage): Accelerate using OpenMP.
> - magick/image.c (TextureImage): Accelerate using OpenMP.
> - magick/render.c (DrawAffineImage): Accelerate using OpenMP.

> - coders/msl.c: Applied patches from Max at hohenegger.eu which fix a MSL parsing error related to gamma, and erroneous text comments which claim that elements can't have attributes.

2008-09-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/resize.c (ResizeImage): Move OpenMP instrumentation to outer loop so that eventually there can be more performance.

(PixelIterateDualRead): Add a description argument and progress monitor support. (PixelIterateDualModify): Add a description argument and progress monitor support.
> - magick/resize.c (HorizontalFilter, VerticalFilter): Switch back to RoundSignedToQuantum() since some pixels were experiencing underflow. Localize some variables so that we don't have to declare them as private for OpenMP.

2008-05-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac, magick/resize.c, PerlMagick/Makefile.PL.in: Added OpenMP support for parallelizing a task across multiple cores.

2008-05-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac, magick/nt_base.h: Fix using libbz2 under MinGW.
> - coders/{msl.c, svg.c, url.c}: Fix compilation with modern libxml2 under MinGW.

2008-05-08 Josue Andrade Gomes <josuegomes@gmail.com>

> - magick/nt_base.h, libxml/include/win32config.h (vsnprintf): Fixed compilation issue noticed with Visual C++ 2008.

2008-05-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/magick.c (GetMagickInfo): Simplify implementation. (RegisterMagickInfo): Remove any existing entry since module loading may result in duplicate entries.

2008-05-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - libtool: Update to libtool 1.2.4.
> - magick/magick.h (MagickInfo): Store string attributes as const char * to statically allocated data rather than as heap allocated strings. THIS IS AN INTERFACE CHANGE. Using a coder written to the old interface is non-fatal but may resemble a small memory leak. The reason for the change is to avoid at least 880 needless malloc()/strlen()/strlcpy() operations at initialization time, and at least 880 free() calls at destruction time. While these operations did not take long, they are still an unnecessary overhead, which is increased in thread-safe applications.
> - magick/module.c (OpenModule): Ignore requests to open modules
>     which have already been opened.
> - GraphicsMagick.spec.in: Add --with-included-ltdl to the default options since this seems safest until the libltdl validation logic is fully robust. This should be made user-configurable in the future.
> - magick/Makefile.am (magick_libGraphicsMagick_la_LIBADD): Apply libltdl dependency argument as required for building.
> - configure.ac: Intuit if the GraphicsMagick library will depend on -lltdl.
> - Magick++/bin/GraphicsMagick++-config.in: Use substitutions rather than invoking GraphicsMagick-config in order to determine GraphicsMagick library usage requirements. This avoids problems when GraphicsMagick-config is not in the executable search path.

2008-05-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - GraphicsMagick.spec.in: NEWS was renamed to NEWS.txt. Enable libtool verbose output so it is possible to diagnose build failures.

2008-05-01 Fojtik Jaroslav <JaFojtik@seznam.cz>

> - mat.c: gm convert -limit Pixels 1 input_gray_lsb_16bit.mat crap.miff don't rotate partial image.

2008-04-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/magick.c (DestroyMagickInfoList): Use DestroyMagickInfo(). (UnregisterMagickInfo): Use DestroyMagickInfo(). (RegisterMagickInfo): Simplify dramatically by adding to the front of the list rather than maintaining alpha order.
> - magick/image.c (DestroyImageInfo): Tidy up and simplify code.
> - magick/constitute.c (WriteImage): Comment out the "bi-modal delegate" execution code until we determine what value it offers. The test suite passes without it.
> - magick/magick.h (struct MagickInfo): There is no need for name to be allocated data so make it const. (DestroyMagickInfo): Add a static function to destroy a MagickInfo structure. Renamed previous DestroyMagickInfo to DestroyMagickInfoList and made it static.

2008-04-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - version.sh: GraphicsMagick 1.2 released. CVS head is now 1.3 development.
> - png: Updated libpng to 1.2.27.

2008-04-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/effect.c (MedianFilterImage): Fixes to compile on ARM CPU.

2008-04-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/magick.h (MagickInfo): Remove image_info member since I can not find any purpose for it.
> - coders/tiff.c (WriteTIFFImage): Remove assertion check on scanline size since it has not caught anything.
> - magick/image.c (SetImageInfo): Ensure that the file extension does not trigger unwanted activity such as access to an X11 server, printer, or the launch delegate.
> - config/Makefile.am (configshare_DATA): Install colors.mgk in share path.
> - magick/blob.c (GetConfigureBlob): Search share config path prior to lib config path.

2008-04-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/png.c (WriteOnePNGImage): TrueColor RGB was usually written rather than the desired more compact format. This is a first pass at fixing that.

2008-04-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - BENCHMARKS.txt: Added a benchmark summary.

2008-04-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

(CycleColormapImage): Added progress monitor support. (GetImageBoundingBox): Added progress monitor support. (SortColormapByIntensity): Added progress monitor support.

2008-04-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac, magick/Makefile.am: Don't use libtdl unless we are supposed to be using it!
> - libtool: Updated to GNU libtool 1.2960 2008-04-19.
> - configure.ac, magick/delegate.h: It seems that the modern convention is to store ghostscript headers in a subdirectory called ghostscript rather than ps. We don't actually need Ghostscript errors.h and that is a good thing since it seems that some newer Ghostscript calls it ierrors.h

2008-04-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - VisualMagick/installer/inc/files-dlls.isx: Comment out inclusion of X11 support DLLs.

2008-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac: Updated to Autoconf 2.62.

2008-04-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (MogrifyImageCommand): New -create-directories option automatically creates subdirectories as needed when -output-directory option is used. This is useful when one directory tree of files is being mogrified to a new tree.

2008-04-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/utility.c (MagickCreateDirectoryPath): New function to create a directory path. Will be used later.

> - magick/constitute.c (ExportImagePixelArea): GrayQuantum case for DirectClass pixels was sometimes writing a zero byte one past the end of the allocated buffer. Thanks to Josue Gomes for reporting this bug.

2008-04-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/{pcd.c,pcx.c,pdb.c,pict.c,stegano.c,wpg.c,xcf.c}: Warnings reduction.
> - magick/{channel.c,image.c,unix_port.c,render.c}: Warnings reduction.
> - coders/mat.c: Convert C99 comments to C89 comments so code can compile with a C89 compiler.
> - coders/tiff.c (WriteTIFFImage): Add an assertion to enforce that the bytes output to the scanline is no more than the bytes allocated for the scanline.
> - NEWS.txt: Updated with latest NEWS.

2008-04-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/pdf.c (WritePDFImage): Default to ZIP compression if available. Ignore Image compression setting since the useful value (set by the user) usually comes from ImageInfo.
> - coders/png.c (WriteOnePNGImage): Fix progress monitor when writing PNG.
> - magick/channel.c (GetImageChannelDepth): Added progress monitor support.
> - magick/signature.c (SignatureImage): Added progress monitor support.

> - magick/blob.c (ImageToBlob): Fix typo in cast.

2008-03-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - CONTRIBUTE.txt: Convert contribute.html to reStucturedText format and generate HTML version from it.
> - PROCESS.txt: Convert description of development process to reStucturedText format and generate HTML version from it.
> - INSTALL-windows.txt: Add instructions for how to install from setup.exe style installer. Also add instructions for how the distribution package is built.
> - Copyright.txt: Reformat in reStucturedText format and generate HTML version from it.
> - VisualMagick/installer/inc/body.isx: No longer include development headers and libraries in the Windows DLL install package since they are large and they may only work with the version of Visual C++ used to perform the build. It is much safer for the developer to build the package from source with his own compiler.

2008-03-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Fix compilation issues with Microsoft Visual Studio.

2008-03-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2008-03-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/dpx.c (WriteDPXImage): Support writing image which is already in a YCbCr colorspace. (ReadDPXImage): Return YCbCr images in YCbCr colorspace unless they are also Cineon log encoded.
> - magick/image.c (CloneImage): Use CloneImageAttributes().
> - magick/attribute.c (CloneImageAttributes): New function for copying image attributes from one image to another.
> - magick/utility.c (TranslateTextEx): Check if the pixel cache is initialized before using a function which requires using it. Thanks to Micha³ Kowalczuk for bringing this issue to my attention.
> - magick/attribute.c (SetImageAttribute): Only apply transformations to "comment" and "label" attributes.
> - magick/pixel_cache.c (GetPixelCachePresent): New function to test if the image pixel cache is present and initialized.

2008-03-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - PerlMagick/t/read.t: Add input_logical_lsb_08bit.mat to PerlMagick tests.
> - magick/nt_feature.c (CropImageToHBITMAP, ImageToHBITMAP): Use GlobalFree() to free bitmap handle.

2008-03-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - PerlMagick/t/read.t: Added/adjusted WPG test files from Jaroslav Fojtik.

2008-03-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2008-02-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - www/body.html: Update to mention 1.1.11 release.

2008-02-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/colorspace.c (RndToInt): Cast result to unsigned int rather than int in order to avoid possible value truncation with Q32 build. Problem was reported by Kai-Uwe Behrmann. (TransformRGBImage): Fix loop iterator which was looping one past the end of the array. Reported by Kai-Uwe Behrmann.
> - magick/command.c: Added a -set option to the composite, convert, display, mogrify, import commands in order to allow setting an image attribute.

2008-02-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - PerlMagick/Magick.xs: Use MagickAcquireMemory() rather than AquireMemory().
> - coders/xwd.c (ReadXWDImage): Eliminate integer overflow vulnerability (IDefense 09.19.07).
> - coders/xbm.c (ReadXBMImage): ditto
> - coders/xcf.c (ReadXCFImage): ditto

2008-02-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/tiff.c (WriteTIFFImage): The RFC 3949 specification for Internet FAX recommends LSB2MSB fill order so document that.

2008-02-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/tiff.c (WriteTIFFImage): Use -define tiff:fill-order={msb2lsb|lsb2msb} to control TIFF bit fill order.

2008-02-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac: Updated to latest CVS libtool.
> - coders/tiff.c (CompressionSupported): Use TIFFGetConfiguredCODECs() to test if a requested compression type is supported by libtiff. Based on advice from Frank Warmerdam.
> - configure.ac: Add test for TIFFGetConfiguredCODECs() in libtiff.

2008-02-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/tiff.c: With libtiff 3.6.1, including tiff.h and tiffio.h is not sufficient to obtain the definitions from tiffconf.h so libtiff is assumed to not support any features, such as compression. Avoid this problem by explicitly including tiffconf.h if it is found. This resolves SourceForge issue [1883527] compression of tiff-file has no effect.

2008-02-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - VisualMagick/installer/inc/setup.isx: Set Inno Setup installer compression to "lzma/max".
> - PerlMagick/Magick.xs: Eliminate use of memory allocation macros since these failed miserably under Windows where it seems that malloc, free, and realloc are redefined via macros by the Perl build environment. This reverts changes made on 2007-12-01.
> - magick/memory.c (MagickAcquireMemoryArray): Use implementation from the 1.1 branch.
> - magick/utility.h: Remove MagickSafeMultiplySize_t since it seems that use of inline functions in Windows is a disaster area.

2008-02-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Makefile.am (windows-dist): Create a 7z compressed Windows comprehensive source package. See http://www.7-zip.org/ for information on Windows 7-Zip and http://p7zip.sourceforge.net/ for information on portable 7-Zip (P7ZIP).

2008-02-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/tiff.c (WriteTIFFImage): Add logging for image resolution and resolution units.

> - magick/Makefile.am: Update magick_libGraphicsMagick_la_DEPENDENCIES to use LTDLDEPS.

2008-01-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/image.c (SetImageInfo): Successfully read existing file names in the form file[123] which were failing to read since they appear to be a valid sub-image specification.

2008-01-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/utility.c (ExpandFilenames): If a filename appears to contain a wildcard specification, first check to see if there is file matching the unexpanded wildcard prior to engaging in the slow task of wildcard expansion. Without this fix, expanding the command line takes a very long time if there are a huge number of files in the directory, and some file names appear to contain wildcard specifications. Inspired by SourceForge bug reports [ 1878992 ] "literal square brackets in file name cause large delay" and [ 1783209 ] "converting runs slowly when subimage is specified", but this might not be the complete fix for the problem.

2008-01-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Makefile.am: Update to Automake 1.10.1 and enable generation of an lzma compressed source package.

2008-01-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac: Added configure option --with-umem to enable use of the umem memory allocation library available in Solaris 9, Update 3 and later, or from https://labs.omniti.com/trac/portableumem/. This library supports concurrency in multi-threaded programs and supports debugging memory issues. See http://developers.sun.com/solaris/articles/libumem_library.html for a description of how to use the library for debugging memory issues.

2008-01-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (VersionCommand): Include a "Large Memory" item in the Feature Support list.
> - coders/png.c (RegisterPNGImage): Remove reference to dead PNG ftp site.
> - VisualMagick/configure/configure.cpp (InitInstance): Remove project dependency on dxguid.lib (Direct-X).

2008-01-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac: Update libtool to latest CVS version.

2008-01-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (DisplayImageCommand): No longer default to reading standard input if stdin fails isatty() test. This behavior was causing failure to launch from Gnome and it is difficult to work around the issue from within a .desktop file. (AnimateImageCommand): No longer default to reading standard input if stdin fails isatty() test.
