# GraphicsMagick ChangeLog - 2010

2011-01-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - wand/magick_wand.c (MagickDescribeImage): Was sending descriptive output to stdout rather than returning it in an allocated string as intended.

2011-01-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/draw.c, wand/drawing_wand.c (MvgPrintf): Update to handle C99 vsnprintf() return values.

> - magick/draw.c, wand/drawing_wand.c (DrawAnnotation): Linux glibc does not pass extended text characters if "%.1024s" formatting convention is used. Apparently it assumes that such characters may be UTF8 and returns -1 rather than outputting the string, even if it is assured to fit.

2010-12-30 Fojtik Jaroslav <JaFojtik@seznam.cz>

> - coders/mat.c Matlab file level clarification.

2010-12-27 Fojtik Jaroslav <JaFojtik@seznam.cz>

> - coders/mac.c New MacPaint image format reader added.

2010-12-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/tiff.c (WriteTIFFImage): Default to using a LZMAPRESET value of 1 based on testing which observed minimal benefit, and substantially more cost, from larger values. Value may be specified by the user using command line syntax like -define tiff:lzmapreset=7 for purposes of further experimentation. Also adjusted default strip memory values for each preset level.

2010-12-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - PerlMagick/Magick.xs: Add LZMA support to PerlMagick.

> - coders/tiff.c (WriteTIFFImage): Add TIFF LZMA compressor support.

2010-12-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (MogrifyImages): Should send -verbose output to stderr rather than stdout since otherwise usage in pipelines may be broken. Resolves SourceForge issue 3131790 "AVS -verbose prints to stdout".

2010-11-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - libtool: Upgrade to libtool 2.4.

> - coders/pnm.c (ReadPNMImage): Start work on reading NetPBM PAM format. Parses PAM header but pixels are not returned yet.

> - magick/magic.c (StaticMagic): Be more specific when identifying PNM subformats. Return the specific subformat name PBM, PGM, or PPM rather than PNM. XV P7 format is now identified as "P7 332". Add detection of NetPBM PAM format.

2010-11-04 Glenn Randers-Pehrson <glennrp@simple...>

> - magick/effect.c: Added 5x5, 6x6, and 7x7 circular ordered dither patterns to create a halftone effect.

2010-09-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - doc/options.imdoc: Document pcl:fit-to-page define.

> - coders/pcl.c: Fix issue with printing a bi-level image on Konica-Minolta printers. Define pcl:fit-to-page in order for the printer to scale the image to fit the page. Patch by John Sergeant.

2010-09-19 Glenn Randers-Pehrson <glennrp@simple...>

> - coders/png.c: removed an apparently harmless extra invocation of ScaleShortToQuantum() due to cut-and-paste error in the update of 2010-06-02. Also added a line to explicitly set the opacity of the background_color to OpaqueOpacity.

2010-09-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/pdf.c (ReadPDFImage): Enable use of PDF crop box via -define pdf:use-cropbox=true. Patch contributed by Chris Gilling. SourceForge patch ID 3063794, "Add support for using crop box for pdf import".

2010-09-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Magick++/lib/Image.cpp (backgroundColor, borderColor, matteColor): Opacity part of user-specified color needs to be preserved. Problem was reported by Alexander Zheltov.

2010-09-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Makefile.am: Applied Automake 1.11.1 patch by Ralf Wildenhues which is necessary for the test suite to pass under Windows/MinGW due to command line length limits.

2010-09-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/draw.c, wand/drawing_wand.c: Pass full user-provided double precision resolution to renderer. Truncating the resolution causes problems in some cases. Resolves SourceForge bug 3058387 "Incorrect Copy Compositing through C interface".

2010-09-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/utility.c (StringToList): Fix performance problem caused by using strlcpy.

> - coders/pnm.c (ReadPNMImage): Q8 build should be able to read 16-bit PGM images.

2010-09-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (MontageImageCommand): Fix memory leak of MontageInfo structure allocation in error handling path.

> - magick/montage.c (MontageImages): Fix crash observed with "-geometry x+0+0". Problem reported by Simon Rainer.

2010-08-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Makefile.am: Update to Automake 1.11.1.

2010-08-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac: Use AC_USE_SYSTEM_EXTENSIONS to enable system API extensions.

2010-08-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/pixel_cache.c (ModifyCache): Fix deadlock in ClonePixelCache() which was caused by using the same semaphore pointer in the source and destination images. Problem was reported by Stefan Schramowski.

2010-08-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/info.c (WriteINFOImage): Added an INFO coder which produces textual image description output similar to identify but may be used with convert like "gm convert myfile info:-". Feature suggested by Stefan Schramowski.

2010-08-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - tests/Makefile.am (TESTS_PS_XFAIL_TESTS): Expect EPT tests to fail if Ghostscript is missing.

> - configure.ac: Updated to Autoconf 2.67.

> - magick/render.c (DrawImage): Use StringToGravityType() to parse gravity values.

2010-07-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - doc/options.imdoc: Document histogram-threshold setting.

> - magick/enhance.c (NormalizeImage): Add support for histogram-threshold setting to specify the percentage of the histogram to discard when computing image normalization parameters (default is 0.1%). For example -set histogram-threshold 0.01 -normalize.

> - www/api/types.rst: Update Image structure member documentation.

2010-07-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac: Add a test for posix_spawnp(). Results may be used in later development.

2010-07-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - tests/Makefile.am (TESTS_PS_XFAIL_TESTS): PDF tests are expected to fail if Ghostscript is not available.

> - magick/utility.c (MagickStrlCat, MagickStrlCpy): Add handling for the case where size is zero in order to be conformant with the strlcat() and strlcpy() formal descriptions. GraphicsMagick does its best to never pass a size of zero so an assertion that size is not zero remains in order to help catch bugs in GraphicsMagick. Issue was reported by Albert Cahalan.

2010-07-10 Glenn Randers-Pehrson <glennrp@simple...>

> - coders/png.c: Always scale tRNS color to 16-bit short. Otherwise, transparency was sometimes lost while reading PNG files whose depth is different from the Quantum depth.

2010-07-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/tiff.c (LOG_TIFF_BLOB_IO): Define LOG_TIFF_BLOB_IO=1 when building GraphicsMagick in order to enable verbose logging from the TIFFClientOpen() registered callbacks when coder logging is enabled.

2010-06-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - tests/rwfile.c: Deal with formats which don't have an extension by prepending the magic specifier to the file name specification.

> - coders/mpr.c (RegisterMPRImage): MPR and MPRI are not useful file extensions.

> - magick/command.c (CommandAccessMonitor): If the environment variable MAGICK_ACCESS_MONITOR is set to TRUE then also log invocations of the access monitor callback when -monitor is specified. This feature is intended to assist with understanding when the access monitor is invoked, and the arguments which are passed.

> - magick/blob.c (OpenBlob): Throw an exception on error rather than depending on the invoking code to do so. Resolves SourceForge bug #3023437 "Magick::Image::ping() does not throw exception in all cases".

2010-06-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (MogrifyImage): The -colors, -map, and -monochrome options now take effect immediately rather than at the end of all other processing. This is is more intuitive and reasonable but may impact the output of scripts which place these options prior to additional image processing operations.

2010-06-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/blob.c (BlobToImage): If a temporary file must be used and the user has specified magic, then preserve the magic specifier when reading the temporary file.

> - coders/mat.c (RegisterMATImage): More accurately describe MATLAB format support as "MATLAB Level 5".

> - magick/magic.c (StaticMagic): Automatically detect MATLAB Level 5 format based on file header.

> - PerlMagick/PerlMagickCheck.sh.in: Run PerlMagick tests in verbose mode so that all test output appears in "test-suite.log" if there is a failure.

> - coders/Makefile.am (coders_mat_la_LIBADD): MAT coder is optionally dependent on zlib so zlib should be listed as a dependency.

> - magick/blob.c (BlobToFile): MAGICK_IO_FSYNC=TRUE in the environment should cause file data to be explicitly synchronized prior to close.

2010-06-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - VisualMagick/installer/inc/files-documentation.isx: There are not currently any JPEG files in the www/images directory to distribute.

2010-06-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - ltdl/config/ltmain.sh: Update libtool to 2.2.10.

> - magick/profile.c: Support lcms 2.0.

> - configure.ac: Add support for configuring for lcms 2.0, controlled via a new --without-lcms2 option. By default lcms v2 is used if it is available, otherwise v1.1X is used if it is available.

2010-06-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - ltdl/config/ltmain.sh: Update libtool to 2.2.8.

2010-06-02 Glenn Randers-Pehrson <glennrp@simple...>

> - coders/png.c correctly scale bKGD chunk data in Q16 build

2010-05-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - www/Magick++/Image.rst: Fix documentation error which wrongly recommended multiplication by size of PixelPacket. Correction by Roel Baardman.

2010-05-23 Fojtik Jaroslav <JaFojtik@seznam.cz>

> - coders/txt.c (ReadTXTImage): Ability to read multiple images.

2010-05-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/constitute.c (DispatchImage): K channel was always output as black for "CMYK" specification unless image matte flag was True. Bug report and proposed solution by Lance Brown.

2010-05-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/shear.c (ShearImage): When one of the shear angles was specified as zero, the shear request was ignored entirely. An simple optimization was using || rather than && to test the angles. Resolves SourceForge issue #2991685 "Shear command does not handle zero angles correctly".

2010-05-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/magick.c (InitializeMagick, DestroyMagick): InitializeMagick and DestroyMagick should be fully thread safe.

2010-05-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/gif.c (ReadGIFImage): Set the opacity value of the opaque color to transparent. Patch by Tim Baker.

> - magick/image.c (SetImageColor): New function which is similar to SetImage() but which accepts the pixel color as a parameter rather than using the image background color. Patch by Tim Baker.

> - magick/transform.c (CoalesceImages): When applying background disposal, fill the image with the transparent color, if one exists. Patch by Tim Baker. Resolves SourceForge patch ID 2989472.

2010-05-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/txt.c (ReadTXTImage): Matte channel was not being enabled for non-opaque images. (ReadTXTImage): Opacity values need to be inverted prior to ingestion.

2010-04-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - doc/options.imdoc: Documentation for -flatten and -mosaic has been improved.

> - magick/transform.c (MosaicImages): The -mosaic command now respects the composition option specified by -compose as well as the image background color specified by -background.

2010-04-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/*.c, magick/*.c: Eliminate many benign data race conditions.

2010-04-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - GraphicsMagick.spec.in: Avoid duplicate copies of documentation files. Put documentation into a versioned directory as used by Red Hat and CentOS. Include archive libraries in developer package.

> - PerlMagick/Makefile.PL.in: Include support for DESTDIR so that RPM builds find the installed GraphicsMagick library.

2010-04-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac: Under Solaris, make sure that OpenWindows Type1 fonts do exist before deciding to use them. OpenSolaris does not provide these fonts.

2010-04-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - GraphicsMagick.spec.in: Fix RPM build. PerlMagick was not being built due to Makefile changes. Resolves SourceForge issue #2952696 "RPM build broken: (Perl) file not found by glob".

> - magick/quantize.c (ReduceImageColors): Progress message should include the image file name.

2010-03-24 Glenn Randers-Pehrson <glennrp@simple...>

> - Revised coders/jpeg.c to preserve the Exif profile.

2010-03-24 Glenn Randers-Pehrson <glennrp@simple...>

> - coders/png.c (ReadOnePNGImage): Eliminated some of the deprecated direct access to ping_info->members. Eliminated support of very old libpng versions (1.0.11 and earlier).

2010-03-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/delegate.c (GetPostscriptDelegateInfo): Add support for invoking "gs-cmyk" and "gs-cmyka" entries in delegates.mgk when ColorSeparationType or ColorSeparationMatteType is requested. Requisite entries in delegates.mgk are left for the user to add.

2010-03-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/magick.c (InitializeMagick): Don't initialize locale settings in InitializeMagick(). Resolves SourceForge bug #2967282 "setlocale called by GraphicsMagick".

2010-03-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/{command.c, display.c}: Make sure that animate, display, and identify report any error only once, and then proceed to the next file name rather than quitting. Problem was reported by Patrick Welche.

2010-03-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - PerlMagick/Makefile.am: Update PerlMagick/Magick.pm in the source tree (as required) since it is distributed source and contains the current version number.

2010-03-03 Glenn Randers-Pehrson <glennrp@simple...>

> - coders/png.c: restored missing "US" in PNG_USER_CHUNK_CACHE_MAX at line 102. Added some (unsigned long) typecasts on print statements to stifle warnings.

2010-03-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - png: Updated libpng to 1.2.43. Resolves CVE-2010-0205 as pertains to GraphicsMagick Windows build.

2010-03-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - tests/rwfile_DCX_*.sh: Add tests for reading and writing DCX.

> - coders/pcx.c (WritePCXImage): DCX is not the same as PCX so only write DCX when requested to (and vice-versa).

> - utilities/tests/convert-pipe-out.sh: New test to verify that convert can write to stdout.

> - utilities/tests/convert-pipe-in.sh: New test to verify that convert can read from stdin.

> - utilities/tests/convert-pipe-filter.sh: New test to verify that convert works properly as a filter.

> - magick/image.c (SetImageInfo): The rectify parameter was found to not be sufficient to meet requirements since it was overloaded. The utilities would malfunction (hang or throw an exception) if requested to write to stdout. As a result, this parameter has been changed to a binary flag type parameter. Existing True/False values are mapped to equivalents using the new binary flag. This is intended to resolve Debian bug 571719 "graphicsmagick: "convert" command is broken", reported by Vladimir Stavrinov.

2010-02-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/composite.c (GetCompositionPixelIteratorCallback): OverCompositeOp and AtopCompositeOp may be replaced with CopyCompositeOp in the case where neither image has a matte channel.

> - magick/command.c (ConvertImageCommand, MogrifyImageCommand): Added -extent option to apply a background color canvas behind the image. Added -compose option to allow specifying the composition operator to use.

> - magick/transform.c (ExtentImage): New function apply a background color canvas behind the image.

2010-02-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c: Added a -thumbnail command to all of the GM sub-commands which currently support -resize. This is a resize method optimized for speed when reducing the size of the image (such as when creating thumbnails).

2010-02-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/utility.c (LocaleCompare, LocaleNCompare): Fix array index underflow which occurs if the char type is signed and the character value is in the extended range. Problem reported by Arseny Solokha. Resolves SourceForge patch #2953314.

2010-02-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - Magick++/demo/demo.cpp (main): Split demo output frames into individual files to enable easier viewing.

2010-02-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - doc/GraphicsMagick.imdoc: Improve usage synopsis for convert. SourceForge feature request 2845965 "confusing documentation".

> - magick/display.c (MagickXDisplayImage): Image number was incorrect in window title.

> - magick/render.c (DrawImage): Path points data allocation was much larger than it needed to be. Patch by Vladimir Lukianov. Resolves SourceForge issue 2947851 "Memory allocation error on vector graphics (or mem bomb)".

> - magick/constitute.c (WriteImages): +adjoin was not working correctly for the case when only one image frame is present. With +adjoin and writing one frame to "foo%d.jpg" it was outputting "foo%d.jpg" rather than "foo0.jpg". Problem reported by Frans Coetzee.

2010-02-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - doc/imdoc2man: Bare single quotes at the beginning of a line need to be escaped in order to make roff happy. Problem reported by Daniel Kobras.

> - magick/command.c (ImportImageCommand): Don't assign a pointer to static constant data into an array which uses heap allocated data. Avoids a "double free" error when using gm import -frame. Patch by Daniel Kobras.

> - magick/color_lookup.c (QueryColorname): XPM does not support RGBA color syntax, but it does support RGB. Patch by Daniel Kobras.

> - magick/blob.c (OpenBlob): Only form multi-part filename when required.

> - magick/display.c (MagickXDisplayImage): The display -update option was only working in conjunction with the -delay option with a delay setting of 2 or greater. Problem reported by Sami Liedes. Patch by Vincent MAUGE. Resolves Debian bug ID 414779.

2010-02-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/blob.c (OpenBlob): Only apply scene substitution to the filename if adjoin is false.

> - magick/constitute.c (WriteImage): If adjoin is true, then restore original filename specification since opening the blob modifies it. Resolves Debian bug ID 552998.

> - magick/image.c (SetImageInfo): Don't check filename for scene substitution if adjoin is intentionally false. This allows saving to file names which look like they contain a scene substitution pattern.

> - magick/command.c (MogrifyImage): Convolution failure results in a crash rather than an error report. Resolves Debian bug ID 539251.

> - magick/deprecate.c: The string constants LoadImageText, SaveImageText, LoadImagesText, and SaveImagesText should have been deprecated, rather than being entirely removed.

2010-01-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - www/Makefile.am (install-data-html): Make sure that only the necessary documentation files are installed.

2010-01-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - VisualMagick/installer/inc/body.isx: Strip out executable components which depend on proprietary MFC and ATL libraries. This means that "gmdisplay.exe" and "ImageMagickObject" are no longer distributed or installed via the Windows setup installer. When a new display application is developed based on open source libraries, then the display functionality and associations can be restored.

2010-01-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/transform.c (FlattenImages): Apply the image background color under the initial canvas image if it is non-opaque.

> - magick/composite.c (MagickCompositeImageUnderColor): New private function to apply a color underneath a non-opaque image.

2010-01-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/prefetch.h: New header to provide wrapper macros for compiler-specific explicit prefetch APIs.

> - magick/effect.c (BlurImageScanlines): Solid color images which only differed in the matte channel were not being blurred.

> - magick/color.h (NotPixelMatch,PixelMatch): New macros to fully-compare a pixel, including matte.

> - magick/resource.c (SetMagickResourceLimit): Invoke omp_set_num_threads() to set thread limit if ThreadsResource is requested.

> - magick/pixel_cache.c (AllocateThreadViewSet): The number of cache views to allocate needs to be obtained from omp_get_max_threads(). Otherwise there is a crash if the number of threads is reduced from the original value.

2010-01-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - www/benchmarks.rst: Update benchmark report to compare performance with ImageMagick 6.5.8-10.

2010-01-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/shear.c (RotateImage, ShearImage): Ensure that errors propagate up to the API user. Don't overwrite a detailed exception message with a generic one. Don't return a bogus image if there is an error.

2010-01-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - VisualMagick/installer/inc/files-base.isx: Third party executables not included in the Visual Studio build are no longer bundled in the GraphicsMagick installer. This means that hp2xx.exe, mpeg2dec.exe, and mpeg2enc.exe are no longer distributed.

> - www/Magick++/Image.rst: Emphasize that InitializeMagick() MUST be invoked, and make sure that all of the examples show use of it.

2010-01-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/delegate.c (InvokeDelegate): Use MagickSpawnVP() under Windows as well. (InvokePostscriptDelegate): Use MagickSpawnVP() under Windows as well.

> - magick/utility.c (MagickSpawnVP): Moved from unix_port.c. Updated implementation to use spawnvp() rather than fork()/exec() under Windows.

> - configure.ac: Add check for Windows spawnvp function. Add check for process.h.

> - magick/semaphore.c (DestroySemaphore): POSIX mutex statically initialized via PTHREAD_MUTEX_INITIALIZER should not be destroyed.

> - configure.ac: DisableSlowOpenMP is now the default. Use --enable-openmp-slow to enable OpenMP for algorithms which sometimes run slower rather than faster.

2010-01-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/version.h.in: Added MagickLibInterfaceNewest and MagickLibInterfaceOldest preprocessor defines so that applications may easily test for library versions while compiling.

2010-01-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/render.c (DrawPolygonPrimitive): Use restrict keyword.

> - magick/pixel_iterator.c: Use restrict keyword.

> - utilities/Makefile.am: Modules are supported in the shared library built so list-module.sh test should be expected to pass.

> - configure.ac: Add WITH_SHARED_LIBS conditional.

2010-01-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/version.h.in: Update copyright years.

> - magick/semaphore.c: The return code from all pthread mutex APIs are now checked (not just initialize and destroy), and any error results in an immediate fatal exit.
