1.3.13 (December 24, 2011)
==========================

Security Fixes:

  None

Bug fixes:

  * In I/O blob, don't rewind already open file handle passed to
    OpenBlob() since we don't know the intended state of this file
    handle, and because it prevents appending to an existing file.

  * In AppendImageProfile(), don't leak profile buffer while appending
    a chunk to an existing profile.

  * Fix deadlock in ClonePixelCache() which was caused by using the
    same semaphore pointer in the source and destination images.

  * Removed bogus SyncBlob() code which sometimes caused a crash and
    was not useful.

  * Fixed crash or hang which occured when the user entered CONTROL-C
    while threaded code was being executed.

  * Fix core dump in AcquireOneCacheViewPixelInlined() when the image
    is in CMYK space.

  * In MontageImages (montage), fix crash observed with "-geometry
    x+0+0".

  * The TIFF reader was crashing for images which use the
    TIFFTAG_OPIIMAGEID tag.

  * AppendImages() (-append) was failing when only one image was
    provided.

  * The `animate`, `display`, and `identify` commands now report any
    error only once, and then proceed to the next file name rather
    than quitting.

  * Don't change the locale settings in InitializeMagick() since this
    may cause problems for international users.  API users are still
    responsible for assuring that locale settings don't break floating
    point parsing and output (i.e. floating point decimal needs to be
    '.' rather than ',').

  * RPM build is fixed (PerlMagick build was broken).

  * RPM build installs documentation to expected places on Red Hat
    type systems.

  * Fixes for usage with OpenSolaris.

  * DESTDIR is supported by PerlMagick build.

  * The matte channel was not being properly enabled or respected for
    TXT images.

  * InitializeMagick() and DestroyMagick() are now fully thread safe.

  * When a shear angle was as zero, the shear request was being
    ignored entirely.

  * In DispatchImage(), the `K` channel was always output as black for
    "CMYK" specification unless the image matte flag was True.

  * MATLAB fixes.

  * PNG fixes.

  * PCL fixes for printing bi-level image on Konica-Minolta printers.

  * EPT error handling fixes.

  * JPEG reader was sometimes truncating large IPTC profiles.

  * JPEG writer now handles errors properly rather than allowing
    libjpeg to exit the program (or hanging if driven by Magick++).

  * JPEG reader now treats an unhandled EXP marker as a warning rather
    than a hard error.

  * File open errors are now reliably reported.

  * Improved rendering precision when using the drawing APIs.

  * For the Magick++ Image backgroundColor(), borderColor(), and
    matteColor() methods, preserve the opacity part of the
    user-specified color.

New Features:

  * Add support for drawing text using a bitmap font.

  * benchmark command supports a -stepthreads option to execute the
    specified command with an increasing number of threads to measure
    how an algorithm benefits from threading.  This mode includes a
    column to show the speedup compared with one thread, and the
    Karp-Flatt metric

  * Added Add support for invoking "gs-cmyk" and "gs-cmyka" \ 
entries in
    delegates.mgk when ColorSeparationType or ColorSeparationMatteType
    is requested.  These cause Ghostscript to always output CMYK PAM
    format (even if the input file was not in CMYK format).

  * EXIF profiles are preserved when writing JPEG files.

  * The -mosaic command now respects the composition option specified
    by -compose as well as the image background color specified by
    -background.

  * The TXT coder now supports multiple image frames.

  * For image normalization (-normalize), 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`.

  * Added an `INFO` coder which produces textual image description
    output similar to `identify` but may be used with convert like "gm
    convert myfile info:-".

  * Support application of the PDF crop box via '-define
    pdf:use-cropbox=true'.

  * For PCL printer output, define pcl:fit-to-page in order for the
    printer to scale the image to fit the page.

  * Added order dither 5x5, 6x6, and 7x7 circular dither patterns to
    create a halftone effect.

  * PNM subformats are now reported as the specific subformat rather
    than just "PNM".

  * NetPBM's PAM format is now supported.

  * MacPaint image format reader is added.

  * Added TIFF LZMA compressor support.

  * Added TIFF support for a tiff:group-three-options define to allow
    power-users to set the value of the GROUP3OPTIONS tag.

  * New core C API function SetImageColorRegion() to set the constant
    pixel color for a specified region of the image.

  * New Wand C API function MagickWriteImagesFile() to append images
    to a provided file handle.

  * New Wand C API function MagickSetImageSavedType() to allow
    specifying the storage type used when saving the file (rather than
    changing the current image characteristics).

  * In Wand C API, the functions NewPixelWand(), NewDrawingWand(), and
    NewMagickWand() invoke InitializeMagick() automatically in case
    user forgets to do so.

  * New Wand C API function MagickSetFormat() to allow setting the
    file or blob format before it has been read.

  * New Wand C API function MagickSetDepth() to set the depth used
    when reading from an image format which requires that the depth be
    specified in advance.

Feature improvements:

  * Now compiles properly with libpng 1.4.X and 1.5.X.

  * Lcms 2.X is supported.

Performance Improvements:

  * TGA read performance improved.

  * PNM read/write performance improved.

  * Convolution (-convolve, -sharpen, -guassian, etc.) is faster.

  * Adaptive threshold image (-lat) is faster.

  * Image trimming (-trim) is faster.

Behavior Changes:

  * For DPX format and packed 10 bits, datums are now represented in
    the same (reversed) order for all RGB and YCbCr formats.
    Previously YCbCr 4:4:4 formats were not swapping the word datums
    because the only real-world files encountered did not swap the
    word datums.

  * The -colors, -map, and -monochrome options now take effect
    immediately rather than at the end of all other processing.

  * Removed non-standard multi-frame extension for SGI format.

  * Windows install footprint is more consistent between DLL and
    static builds.

  * LZMA compressed tarball is in 'xz' format rather than deprecated
    'lzma' format.
