  * New version 6.6.8-8.

2011-03-25 6.6.8-8 Cristy  <quetzlzacatenango@image...>
  * Fix memory access bug in CloneString() (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=18382).
  * Avoid infinite loop when no space is available in MagickFormatCaption().

2011-03-25 6.6.8-8 Anthony Thyssen <A.Thyssen@griffith...>
  * Removed the fix for %p and %n escapes, as it was not working right

2011-03-24  6.6.8-7 Cristy  <quetzlzacatenango@image...>
  * New version 6.6.8-7.

2011-03-24  6.6.8-7 Cristy  <quetzlzacatenango@image...>
  * Add support for 16-bit DCM short ints (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18371).

2011-03-23 6.6.8-7 Anthony Thyssen <A.Thyssen@griffith...>
  * Another fix for -sparse-color and unused color channels
  * Finialize the -duplicate option created by Cristy
  * Fix of segmentation fault for second image in %[fx:..] during info:
    (Bug in AcquireFxInfo(), as given start image is not first image)

2011-03-21  6.6.8-7 Glenn Randers-Pehrson <glennrp@image...>
  * Revised the PNG8 encoder to use 50% threshold instead of 0% when
    reducing transparency to binary.  Collapse all resulting fully transparent
    colors into one (the background color), to reduce the compressed filesize.
  * First try the 4-4-4 and 3-3-3 palettes instead of 3-3-2, to preserve
    colors (especially gray) better, when reducing to PNG8.
  * Force the PNG encoder to return image->matte==MagickTrue when the
    format is RGBA or GA or if the tRNS chunk is present, even when the
    image is fully opaque (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18349).

2011-03-21  6.6.8-6 Cristy  <quetzlzacatenango@image...>
  * New version 6.6.8-6.

2011-03-21  6.6.8-6 Glenn Randers-Pehrson <glennrp@image...>
  * Re-enabled reduction of grayscale images (color-type 0) to 2 or 4 bits
    when appropriate (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18098).
  * The "-define PNG:color-type=4" option did not always force the PNG
    encoder to write an all-opaque alpha channel (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18349).

2011-03-14  6.6.8-6 Cristy  <quetzlzacatenango@image...>
  * Fixed memory leak for PDF and Bitmap PSD RLE support (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18317).
  * Support the -statistic option: replace each pixel with corresponding
    statistic from the neighborhood.
  * Add support for -duplicate option.
  * Move configuration files from /usr/share and /usr/lib to /etc and /var.
  * Do not cache the results of fx: otherwise -format
    '%[fx:rand()] %[fx:rand()]' returns the same random numbers.

2011-03-18 6.6.8-6 Anthony Thyssen <A.Thyssen@griffith...>
  * Replaced Minus and Divide Composition methods with Dst and Src
    equivalents. Now users can decide how these non-commutative mathematical
    operators are applied to the images being composited.
  * Fix the percent escape values for  %p, %n  and  %[fx:t], %[fx:n] to
    respectively mean the current images index and the total number of
    images within the current image sequence.

2011-03-17 6.6.8-5 Anthony Thyssen <A.Thyssen@griffith...>
  * Backed out the patch for Variable Blur Composition that was added
    2011-02-13 v6.6.7-7, until I can re-think the problem.
    The existing fix was failing to do circular blurs correctly.

2011-03-14  6.6.8-5 Glenn Randers-Pehrson <glennrp@image...>
  * Fixed a rounding/truncation error while writing the pHYs chunk in the
    png encoder.
  * Don't write text-encoded profile when "-define PNG:exclude-chunk=text,ztxt"
    is present (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17086 and
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18225).

2011-03-14  6.6.8-5 Cristy  <quetzlzacatenango@image...>
  * Add support for the WebP image format.

2011-03-14  6.6.8-5 Anthony Thyssen <A.Thyssen@griffith...>
  * Ensured that -sparse-color preserves unused channels when
    channel limited.  Before this unused channels would be reset to black.

2011-03-11  6.6.8-4 Glenn Randers-Pehrson <glennrp@image...>
  * Don't try to store a bKGD chunk in a PNG8 when there are already
    256 colors in the palette and the background colors is not in that
    palette (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18199);
  * The "-define PNG:exclude-chunk=bKGD" option was also excluding
    the text chunks. (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18253).

2011-03-10  6.6.8-4 Cristy  <quetzlzacatenango@image...>
  * Fx is a mathematical function.  Do not treat transparency as black.
  * No image scene suffix for filenames that include a single bracket (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18267).

2011-03-10  6.6.8-3 Cristy  <quetzlzacatenango@image...>
  * New version 6.6.8-3.

2011-03-10  6.6.8-3 Cristy  <quetzlzacatenango@image...>
  * Boost causes an ambiguity with ssize_t when building PythonMagick.  Add
    patch from Arfrever@gento... to fix the build exception.

2011-03-09  6.6.8-2 Cristy  <quetzlzacatenango@image...>
  * Support the Radiance HDR image format.
  * Update the offset in the black channel when sharpening to avoid incorrect
    results.
  * Do not use GenericReadMethod for TIFF images with 64-bits per sample.

2011-03-06  6.6.8-2 Glenn Randers-Pehrson <glennrp@image...>
  * Throw error message when the requested color-type or bit-depth
    cannot be written by the PNG encoder (error was being thrown
    into the wrong image structure).  (Reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
  * Don't write a PNG text chunk with "density" keyword that overrides the
    PNG pHYs chunk, if the pHYs chunk was not excluded (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18253).
  * Ignore any PNG text chunk with a "density" keyword found by the PNG
    decoder, if the PNG datastream also contains a pHYs chunk.

2011-03-06  6.6.8-1 Cristy  <quetzlzacatenango@image...>
  * New version 6.6.8-1.

2011-03-05  6.6.8-1 Cristy  <quetzlzacatenango@image...>
  * Support PSD files with one layer and one composite layer.
  * We must cast a Quantum type when bit shifting and HDRI is enabled.

2011-03-05  6.6.8-0 Cristy  <quetzlzacatenango@image...>
  * New version 6.6.8-0.

2011-02-27  6.6.8-0 Cristy  <quetzlzacatenango@image...>
  * Add support for the -mode option.

2011-02-27  6.6.8-0 Glenn Randers-Pehrson <glennrp@image...>
  * Fix scaling of new color-reduction method in the PNG encoder (16-bit
    images were scaled down to 0 or 1, or nearly black).
  * Delay opening the PNG output blob until the PNG encoder is ready
    to write the IHDR chunk, to avoid writing zero-length PNG files when
    errors are found while building the palette.  (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).

2011-02-25  6.6.7-10 Cristy  <quetzlzacatenango@image...>
  * New version 6.6.7-10.

2011-02-23  6.6.7-10 Cristy  <quetzlzacatenango@image...>
  * Avoid seg fault in AppendImages() when one image is in the RGB colorspace
    but the other is in the CMYK colorspace.
  * Get rid of 'respect_parenthesis defined but not used' warnings (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=18173).

2011-02-22  6.6.7-10 Glenn Randers-Pehrson <glennrp@image...>
  * Write sub-8-bit grayscale PNG images as palette-indexed PNG images.  This
    usually makes smaller files anyhow.
  * Eliminated a number of redundant tests for gray images in the PNG encoder.
  * Removed now-unused IsMonochromeImage() function from coders/png.c
  * Scan the colormap instead of all of the pixels, when possible, to
    determine whether the image received by the PNG encoder is grayscale
    or black-and-white.
  * Avoid reading from the colormap in coders/png.c when it is NULL (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
  * Add a check whether the PNG "cheap transparency" criteria are met.  That
    is, there is a single transparent color, no semitransparent colors, and
    no opaque color that has the same RGB components as the transparent
    color.  If those aren't met, a color that is transparent in one pixel
    and opaque in another would always be rendered as transparent, so we
    must write a PNG colortype that has an alpha channel (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18167).

2011-02-22  6.6.7-9 Cristy  <quetzlzacatenango@image...>
  * New version 6.6.7-9.

2011-02-22  6.6.7-9 Glenn Randers-Pehrson <glennrp@image...>
  * Disabled reduction of grayscale images (color-type 0) to less than 8 bits
    when writing because this sometimes produced incorrect output (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18098).

2011-02-21  6.6.7-9 Cristy  <quetzlzacatenango@image...>
  * Check image has properties before accessing the splay tree (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18136).

2011-02-15  6.6.7-8 Cristy  <quetzlzacatenango@image...>
  * New version 6.6.7-8.

2011-02-14  6.6.7-8 Glenn Randers-Pehrson <glennrp@image...>
  * The PNG encoder should ignore bogus q->opacity values when image->matte
    is MagickFalse (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18067).

2011-02-14  6.6.7-8 Cristy  <quetzlzacatenango@image...>
  * Use implicit image format when explicit format is bogus (e.g.
    02.13.11-18:43:58.png now writes as PNG).
  * Fix problem with 4GB file seeks on a 32-bit OS.

2011-02-13  6.6.7-7 Anthony Thyssen <A.Thyssen@griffith...>
  * Fixed Variable blur to handle small (< 1.0 sigma) blurs generated
    by the blur map being used, rather than just 'cutoff' suddenly.

2011-02-08  6.6.7-7 Cristy  <quetzlzacatenango@image...>
  * Support 16-bit per pixel YUV image files.
  * Fix off-by-one error in PosterizeImage().
  * Posterize now distributes color uniformly (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17623).
  * Add -smush option (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17953).
  * Repair memory leak in the display program.

2011-02-07  6.6.7-6 Cristy  <quetzlzacatenango@image...>
  * Fix bug in carg() define when HAVE_COMPLEX is not defined (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18030).

2011-02-06  6.6.7-6 Anthony Thyssen <A.Thyssen@griffith...>
  * Default sigma for Gauusian resize filter is now 1/2 for both
    orthogonal resize and cylindrical EWA distortions.

2011-02-02  6.6.7-5 Cristy  <quetzlzacatenango@image...>
  * Check if the font is null in RenderFreetype() to prevent fault (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17890).
  * Eliminate fault when reading WMF image files (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17971).
  * Support multi-page transparent Postscript and PDF image files.
  * The compare fuzz metric now returns the same correct value for
    'xc:white xc:blue -alpha off' and 'xc:white xc:blue -alpha on'.

2011-01-29  6.6.7-4 Paul Heckbert  <ph@cs.cm...>
  * Move coders/tiff.c conditional compile to define TIFF exception /
    semaphore / key when TIFF delegate is disabled.

2011-01-29  6.6.7-4 Glenn Randers-Pehrson <glennrp@image...>
  * Renamed variables, macros, and functions defined/declared in coders/png.c
    that were in the libpng namespace (beginning with "png_" or "PNG_").

2011-01-25  6.6.7-3 Glenn Randers-Pehrson <glennrp@image...>
  * Removed a call to GetNumberColors() from the PNG encoder that was
    only there for debugging purposes and was consuming a huge amount
    of CPU time. (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17799).
  * Sometimes black was still written as transparent, when the PNG
    encoder received an image with image->matte==true but no transparent
    pixels were present. (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17913);

2011-01-24  6.6.7-3 Cristy  <quetzlzacatenango@image...>
  * Remove memory leak from ThrowFileException() macro (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17908).
  * Multiple blue error count by 'count' in ClassifyImageColors()
  * Add support for the AAI image format.

2011-01-22  6.6.7-2 Cristy  <quetzlzacatenango@image...>
  * Accept quoted file paths in indirect file references (e.g. @myFiles.txt).

2011-01-19  6.6.7-2 Glenn Randers-Pehrson <glennrp@image...>
  * Changed the PNG encoder's "transparent_color" from a UShortPixelPacket
    to LongPixelPacket and made the default (65537,65537,65537), which
    can never occur in the PNG image data.  Previously the default was
    (0,0,0) and black pixels would be rendered as as transparent when
    no tRNS chunk was present in the input, which has caused problems
    with some test cases since version 6.6.6-10.
  * Improved the PNG_BUILD_PALETTE section to count opaque, transparent,
    and semitransparent pixels separately.  Previously it wasn't always
    possible to determine if there was a single fully-transparent color,
    to decide whether to write an RGBA or Gray-Alpha image or an RGB or
    Gray image with a tRNS chunk.

2011-01-15  6.6.7-1 Cristy  <quetzlzacatenango@image...>
  * Do not reset image next / previous when detach argument is false for
    CloneImage().
  * Inline cropping no longer fails for inline raw images (e.g.
    -size 640x480 -depth 8 'gray:logo[100x100+200+200]').

2011-01-14  6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
  * Don't let the PNG encoder try to sort the colormap when there are more
    than 256 colors in the image. (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17834).

2011-01-10  6.6.7-1 Cristy  <quetzlzacatenango@image...>
  * Accept escaped % in output filename (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17810).

2011-01-08  6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
  * Quieted some inconsequential warnings in the PNG codec due to a
    change in the type of the PNG iCCP profile from png_charp to png_bytep
    in libpng-1.5.0.

2011-01-03  6.6.7-0 Cristy  <quetzlzacatenango@image...>
  * Handle negative heights for ICO images.

2011-01-02  6.6.7-0 Glenn Randers-Pehrson <glennrp@image...>
  * Recent changes sometimes caused the PNG encoder to select colortype=2
    (Truecolor) instead of 0 (Grayscale) for grayscale images.  This made
    the filesize larger than necessary and caused some of the PerlMagick
    tests to fail.

2011-01-01  6.6.6-10 Glenn Randers-Pehrson <glennrp@image...>
  * The PNG decoder now checks whether the image actually has any transparency
    when the input file contains an alpha channel or a tRNS chunk.  (Reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17748)

2010-12-26  6.6.6-8 Cristy  <quetzlzacatenango@image...>
  * -posterize fails with more than 40 levels (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17741).
  * Add support for the MacPaint image format.
  * Eliminate spurious 'invalid colormap index' exception for 16-bit SGI images
    (bug report by steven.sittser@fligh...).
  * Fix user data length for the CIN image format.

2010-12-21  6.6.6-7 Glenn Randers-Pehrson <glennrp@image...>
  * Use a clone instead of the main image in coders/png.c, so the image
    can still be used later on without being affected by changes made by
    the PNG encoder.
  * Added PNG:exclude-chunk and PNG:include-chunk defines.
  * Revised the -strip option so it behaves as though
    "-define PNG:include-chunk=none,gama" had appeared on the commandline.
  * Avoid writing PNG ancillary chunks in the PNG/MNG/JNG encoder while
    generating the alpha channel for a JNG image.

2010-12-21  6.6.6-7 Anthony Thyssen <A.Thyssen@griffith...>
  * Removed the forced interpolation setting in AcquireResampleFilterThreadSet
    It prevented user defined interpolation settings for -clut, and possibly
    other usage.

2010-12-17  6.6.6-6 Chris Madison  <madisonblu@gmail...>
  * Add LZMA compression support to ImageMagick.
  * Eliminate seg-fault in MvgPrintf().

2010-12-17  6.6.6-6 Glenn Randers-Pehrson <glennrp@image...>
  * Eliminated a redundant quantization step in the PNG encoder.
  * Untangled a confusing but apparently harmless improper loop nesting
    in the PNG encoder.
  * Eliminated redundant "IsGray()" tests from the PNG encoder.

2010-12-14  6.6.6-6 Cristy  <quetzlzacatenango@image...>
  * -format "%[fx:u.p{5,5}]" no longer reports parse exception (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17678).

2010-12-10  6.6.6-5 Glenn Randers-Pehrson <glennrp@image...>
  * Make the PNG encoder always rebuild the palette, to avoid losing
    transparency when it is out of sync with the pixel data (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17655).
  * Eliminated CompressColormapTransFirst() since the palette is already
    compressed and sorted by opacity now when it's recreated.

2010-12-10  6.6.6-5 Cristy  <quetzlzacatenango@image...>
  * Account for virtual canvas for the -flip / -flop options (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17626).
  * Also for -transpose and transverse options
  * Support -metric fuzz option.

2010-12-09  6.6.6-4 Anthony Thyssen <A.Thyssen@griffith...>
  * Replace IsMagickColorSimilar() which provides the Fuzz Factor threshold
    function.  Note function does not calculate 'distance' in total but
    short-circuits when threshold is reached for faster processing.
  * Ordered Dithered handling of Alpha channel was incorrect - fixing
    Bug was introduced v6.6.5-6

2010-12-03  6.6.6-3 Glenn Randers-Pehrson <glennrp@image...>
  * Fixed two more cases where the PNG encoder lost transparency (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17516).

2010-12-01  6.6.6-2 Cristy  <quetzlzacatenango@image...>
  * Affine multiplication reversed when translating (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17570).

2010-11-26  6.6.6-2 Glenn Randers-Pehrson <glennrp@image...>
  * Revised the "c7x7b" and "c7x7w" ordered-dither maps to be complementary
    to each other.

2010-11-27  6.6.6-1 Cristy  <quetzlzacatenango@image...>
  * Add support for -evaluate-sequence median.

2010-11-26  6.6.6-0 Glenn Randers-Pehrson <glennrp@image...>
  * Fixed two more cases where the PNG encoder lost transparency (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17516).

2010-11-23  6.6.6-0 Cristy  <quetzlzacatenango@image...>
  * The policy.xml sets not-to-exceed resource values (e.g. policy memory limit
    1GB, -limit 2GB exceeds policy maximum so memory limit is 1GB).
  * Support NCC (normalized cross correlation) compare metric.

2010-11-21  6.6.5-10 Cristy  <quetzlzacatenango@image...>
  * Fix PNG coder compile error when HDRI is enabled.

2010-11-17  6.6.5-9 Glenn Randers-Pehrson <glennrp@image...>
  * Many of the problems with the PNG encoder have been fixed (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16490).
  * The "-type Optimize" option is now deprecated.  If present, it is treated
    by the PNG encoder the same as if the type were undefined.  Optimization
    is now always performed.  No other formats used the "type Optimize" option.
  * Merged redundant code into LosslessReduceDepth() function in the PNG codec.

2010-11-14  6.6.5-9 Cristy  <quetzlzacatenango@image...>
  * The splice option no longer throws spurious "pixels are not authentic"
    exceptions.
  * Thread the -adaptive-resize option.
  * Set XBM coder height to height not width.

2010-11-14  6.6.5-9 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * Lanczos2Sharp blur tweaked. New blur = 0.9549963639785485.

2010-11-13  6.6.5-9 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * LanczosSharp blur tweaked to minimize worst case deviation from "perfect
    preservation of images which only vary horizontally (or vertically)" under
    no-op. New blur = 0.9812505644269356.

2010-11-08  6.6.5-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * Missing logical operator in tiff.c.

2010-11-08  6.6.5-8 Cristy  <quetzlzacatenango@image...>
  * Only save TIFF image with 1-bit depth if there is no alpha channel.
  * Abandon PSD composite if layer is available.
  * %[fx:mean] is the mean of the default channels (all but opacity) (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17432).

2010-10-29  6.6.5-6 Glenn Randers-Pehrson <glennrp@image...>
  * Added 5x5, 6x6, and 7x7 ordered-dither level maps.

2010-10-30  6.6.5-5 Cristy  <quetzlzacatenango@image...>
  * Do not read configure files in the current directory for the "installed"
    version of ImageMagick.
  * Allow numeric characters in the XPM basename (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17385).

2010-10-29  6.6.5-4 Glenn Randers-Pehrson <glennrp@image...>
  * Revised PNG palette optimization
  * Added some debug logging in coders/png.c.

2010-10-28  6.6.5-3 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * More precise blur values for Lanczos2Sharp and LanczosSharp.
  * Added location of first Mitchell crossing (=8/7) to the filters data
    structure.

2010-10-28  6.6.5-2 Anthony Thyssen <A.Thyssen@griffith...>
  * Added Lanczos2D* filters now named Lanczos2*
  * Reorganization of AcquireFilter() to make it work better

2010-10-25  6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * Clearer EWA filters (LanczosSharp etc) comments.

2010-10-25  6.6.5-1 Anthony Thyssen <A.Thyssen@griffith...>
  * Added LanczosSharp  (3-lobe Lanczos with sharpening)
  * Filter sharpening factors are also always applied regardless of usage.

2010-10-24  6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * CubicBC filter formulas simplified by constant folding. In
    particular, P1 coefficient (always zero) removed from coeff.

2010-10-22  6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * Revert the Robidoux filter to a Keys cubic with C=(108 sqrt 2-29)/398
    (as already specified in the documentation).

2010-10-14  6.6.5-1 Cristy  <quetzlzacatenango@image...>
  * Ignore PS bounding box offsets if -page is set.
  * Use #pragma omp master for dumping single threaded debugging information
    (single caused a fault).
  * Add support for -evaluate exp.

2010-10-12  6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>
  * Added "filter:sigma" expert setting defining the 'sigma' for the Gaussian
    filter only.  This is similar in action to 'blur' but only for Gaussians,
    and does not modify the filters support, allowing you to set a very small
    sigma, without the function 'missing' all pixels.
    (This will allow future adjustment of Gaussians for variable blur mapping)

2010-10-10  6.6.5-0 Cristy  <quetzlzacatenango@image...>
  * Patch for  DrawableRotation() and DrawableTranslation() (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17246).
  * The webp format requires the webpconv delegate program (experimental).

2010-10-05  6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>
  * Replaced "Robidoux" with Cubic 'Keys' filter that is near equivelent to
    the previous sharped "Lanczos2D" filter. (C=0.31089212245300069)
    This also is very similer to a Mitchell filter but specifically designed
    for EWA use and is the new default filter for Distorting Images.
  * Original sharpened Lanczos2D filter now called "Lanczos2Dsharp"

2010-10-08  6.6.4-10 Jerry Gay  <jerry.gay@gmail..>
  * Autodetect file type support in Makefile.PL to prevent test failures

2010-10-05  6.6.4-10 Anthony Thyssen <A.Thyssen@griffith...>
  * Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by
    Andreas Gustafsson in his thesis  "Interactive Image Warping" (page 24)
         http://www.gson.org/thesis/warping-thesis.pdf
  * Added filter "Robidoux" which is a slightly sharpened version of the
    "Lanczos2D" filter (blur=0.958033808) specifically designed to be less
    'blurry' for horizontal and vertical lines in no-op distortions.

2010-10-05  6.6.4-10 Cristy  <quetzlzacatenango@image...>
  * Add support for "pattern:vertical2" and "pattern:horizontal2".
  * Add support for "pattern:vertical3" and "pattern:horizontal3".
  * Properly handle PSD layers with negative offsets.

2010-10-03  6.6.4-9 Cristy  <quetzlzacatenango@image...>
  * Fix memory assertion with --enable-embeddable (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17201).
  * Don't permit access to pixels when pinging an image (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17194).

2010-10-02  6.6.4-9 Anthony Thyssen <A.Thyssen@griffith...>
  * Added sqrt(2) blurring default for Gaussian Filter if used as
    a Cylindrical EWA filter.  This resulted removing the last aliasing
    issue that was present in tests for Gaussian EWA resampling. Of course
    it is still a very blurry filter for default use in EWA.
  * Adjusted Variable Mapping Blur Composition so user arguments actual
    relate properly to the sigma of the blur for a maximum mapping value.
  * Fix horizon anti-alising for output-scaled perspective distortions.
  * 'Bessel' filter is now offically and more accuritally named 'Jinc'
    however 'Bessel' while not visible as a filter option can still be used
    as an internal alias for 'Jinc'.

2010-09-28  6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * Chantal Racette double checked the bounding parallelogram computation
    in resample.c (and I tightened the comments).

2010-09-28  6.6.4-8 Cristy  <quetzlzacatenango@image...>
  * Temporary files not always deleted (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=15960).

2010-09-28  6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
  * Bug fix for -filter point distorts (occasional generating black pixels)

2010-09-27  6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * Simplified the ClampUpAxes code, the use of its outputs, its comments,
    and credited Craig DeForest for the "clamp singular values" idea.
  * No reason to have "insane" precision Sinc in resize.c: Use
    the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.

2010-09-27  6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
  * Replace the blurry "High Quality EWA" technique with a 'Clamped EWA'
    for Distort Resampling.  This makes -distort a whole lot nicer
    and allows for the use of better cylindrical filters.

2010-09-26  6.6.4-7 Anthony Thyssen <A.Thyssen@griffith...>
  * Fix Point filter for ResizeImage() caused by support limiting the
    Box weighting function.

2010-09-26  6.6.4-6 Cristy  <quetzlzacatenango@image...>
  * Don't allow resize filter weights to go to zero (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17132).

2010-09-24  6.6.4-6 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * Now that MagickPIL is a MagickRealType, some casts are unneeded.

2010-09-21  6.6.4-6 Cristy  <quetzlzacatenango@image...>
  * Do not break words if caption size is absolute (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17123).
  * Don't define HAVE_THREADS for --without-threads configure script option.

2010-09-20  6.6.4-5 Nicolas Robidoux <nicolas.robidoux@gmai...>
  * Modified "magick/resize.c" so that MagickPIL is a MagickRealType number.
    Some computations were needlessly done in long double precision because
    PIL forced an automatic upcast wherever it appeared. Changed its name to
    MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
  * Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt
    call instead of two trig calls.

2010-09-20  6.6.4-5 Anthony Thyssen <A.Thyssen@griffith...>
  * modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
  * Removed LanczosFast from supported filters (SincFast*SincFast is faster)

2010-09-19  6.6.4-5 Cristy  <quetzlzacatenango@image...>
  * If IPTC profile is not embedded in an 8bim resource, declare it IPTC
    rather than 8BIM.
  * Support %[version] and %[copyright].
  * Improve performance of the pixel cache.

2010-09-18  6.6.4-4 Cristy  <quetzlzacatenango@image...>
  * Automatically set the quantum depth to 16 for HDRI.

2010-09-16  6.6.4-2 Cristy  <quetzlzacatenango@image...>
  * IPTC profile not always wrapped properly inside an 8BIM profile.
  * TIFF tile geometry must be divisible by 16.

2010-09-15  6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
  * Rename of SincPolynomial to SincFast for easier user understanding
  * Ditto for LanczosChebyshev to LanzcosFast

2010-09-14  6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
  * Switch default resize filters to using the faster SincPolynomial
    filter by default internally.  However 'Sinc' will still use the
    Trigonometric function, and can be used to assign the trig version
    of Sinc() to filters using the filter expert options.
  * The default filter for 'distort' was found to be a very blurry inaccurate
    filter function.  It was removed and replaced with a correct Gaussian
    filter (as used by resize)
  * Added a switch so that "-interpolate filter" will force the use of
    a cylindrical filter for ALL pixels in distorted images.  That is you can
    use that switch to use a cylindrical filter even for images that are
    being enlarged by the distortion.  However EWA is still currently using
    a fixed 2.0 sampling radius.  This switch complements the use of "-filter
    point" which turns off EWA filters in favor of interpolation for all
    pixels in a distorted image.  BOTH switches should not be used together.
  * A bug in the support radius of the EWA resampling function was found,
    now that correctly defined resize filters are being used. Suddenly Normal
    Gaussian distortions are not so blurry, and tests with distortions of
    the 'Rings' image show extremely good and clear results, with only minimal
    blurring.  The filter 'blur' expert option can be used to adjust this
    further.

    The above represents a major improvement forward in the quality of the
    image distortion operator. But near-unity distortions (no scaling) are
    still overly blurry.

2010-09-13  6.6.4-2 Cristy  <quetzlzacatenango@image...>
  * Don't negate the geometry offset for the -extent option.

2010-09-09  6.6.4-1 Cristy  <quetzlzacatenango@image...>
  * The RGBO format is now listed as a supported format.

2010-09-07  6.6.4-1 Anthony Thyssen <A.Thyssen@griffith...>
  * Added the Nicolas Robidoux and Chantal Racette  Lanczos resize filter
    function as "LanczosChebyshev" as faster alternative to Lanczos.
  * Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of
    the Sinc Trigonometric resize filter, as a proper filter to allow
    direct comparision and speed testing of the filter.
  * Expanded the "-set option:filter:verbose 1" output, so as to also include
    the actual functions and other values that were used to create the filter.

2010-09-02  6.6.4-0 el_supremo  <digipete@shaw...>

  * Only use the first alpha channel in PSD image.
  * Only use XPM complying colors for XPM images (e.g. green is rgb(0,255,0)).

2010-07-27  6.6.3-2 Glenn Randers-Pehrson <glennrp@image...>
  * Eliminate useless message about assuming zero delay when writing
    a single-frame MNG, and changed it from Error to Warning when
    writing a multiple-frame MNG.

2010-07-25  6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
  * Don't "ping" a PNG image if it is embedded in a MNG.  Otherwise the
    reader tries to read MNG chunks from the interior of the embedded PNG,
    resulting in an erroneous "corrupted image" message.

2010-07-09  6.6.3-1 Cristy  <quetzlzacatenango@image...>
  * Fix memory leak in for corrupt BMP images (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16600).
  * Repair several issues when writing to stdout (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16620).
  * A GIF image with the .bgr extension is still a GIF (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16662).

2010-07-07  6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
  * The PNG decoder failed to handle the tRNS chunk properly for grayscale
    images where the PNG bit_depth was not the same as the quantum depth,
    and the transparent color was not black.

2010-07-01  6.6.3-0 Chris Madison  <madisonblu@gmail...>
  * Pinging the DJVU image format no longer faults.
  * Check for time-limit-exceeded in only one thread.
  * Reading filenames from a file (e.g. @filenames) no longer includes the

2010-05-23  6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
  * Third Re-write of MorphologyApply() to better handle compound methods.
  * Implemented  -set option:morphology:compose for merging results of
    multiple kernels. "None" means re-iterate results with next kernel.
    While "Undefined" means to use the internal default for a method.
    Thinning, Thickening, HitAndMiss, Convolve, Correlate defaults to "None"
    while HitAndMiss defaults to "Lighten" (union of all kernel results).
    Other morphology methods defaults still to be decided.
  * Added HitAndMiss Kernel: Ridges  (find ridges and pixel width lines)
  * Rotation Expansion of single kernels '^' and '@' flags in arguments
    EG: -set option:showkernel 1 -morphology Convolve 'Blur:0x2^'
  * ExpandKernelInfo() (rotation expand) now groks symmetrical kernels.
    So the above will only produce a list of 2 kernels, not 4 kernels

2010-05-18  6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
  * Separation of internal function MorphologyApply() from
    MorphologyImageChannel() to calls to convolve without user settings.

    expand kernel into a rotated list.
    EG: -set option:showkernel 1 -morphology Thinning  '3@: 0,1,0 0,1,0 0,0,0'
  * Allow a scaled unity kernel to be added to kernel (EdgeDet->Sharpen)
    EG: -set option:convolve:scale [kernel_scale][^!],[unity_scale][%]
  * Addition of "Laplacian of Gaussian" (LOG), also known as Mexican Hat
    EG: -morphology convolve LOG:0x1
  * Added FreiChen, Kirsch  Convolution kernels
  * Added Descrete 'Laplacian of Gaussian' kernels (Laplacian type 15 and 19)
  * Added Edges HitAndMiss Kernel

2010-05-17  6.6.2-0 Cristy  <quetzlzacatenango@image...>
  * PSD images require a proper layer to support an alpha channel.
  * Enable PFM endian support.
  * Add context to -border for montage.  Inside the parenthesis it adds a border
    to the image otherwise it sets the border for the layout manager.
  * 24-bit BMP images are not colormapped even if header colors != 0.
  * Set DPX user data like this: -set profile dpx:userdata.txt.
  * Make sure Lab => RGB => Lab survives the round trip.

2010-05-15  6.6.1-10 Cristy  <quetzlzacatenango@image...>
  * Use ScaleCharToQuantum() in coders/src.c (reference

    EG:    -morphology convolve DOG:0x1,3
           -morphology convolve DOB:0x1,3,90
  * Added Prewitt, Roberts, Compass  Convolution Kernels
  * Ring Symbol Kernel (subtraction of Disk from a Disk)

2010-05-13  6.6.1-9 Cristy  <quetzlzacatenango@image...>
  * The pixel buffer was underallocated for some image formats when streaming.

    scaling factor, for easier usage.
  * Bug fix for compose math channel handling and morphology diff usage

2010-05-06  6.6.1-6 Cristy  <quetzlzacatenango@image...>
  * Do not claim gray colorspace if gray image includes a non-gray pixel.
  * Initialize BMP alpha channel to opaque for RGB images.
  * Fixed under allocation for round rectangles.
  * The -list option returns a 0 status as expected.

2010-05-06  6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
  * Made use of new no-'sync' channel enabled mathematical compose methods
    for the difference morphology methods.  These should now work correctly

2010-05-05  6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
  * Rename of "Add" and "Subtract" compositions to "ModulusAdd" and
    "ModulusSubtract" for more clarity of there functions. Old names
    will continue to work as expected.
  * Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow
    normal SVG 'Over' blending specifications, (see next for override)
    Note that this does NOT include the "Plus" composition method which has
    SVG definition for it to use a 'Plus' blending rather than 'Over' blending.

  * By default mathematical compositions work as per SVG definition. That is
    the results are synchronized with 'Over' alpha-blending (except "Plus"
    which uses 'plus' alpha-blending).

    By removing the default 'sync' flag from the -channel setting however
    Break this inter-channel synchronization and do the mathematical operations
    only on the individual channels as specified by the -channel setting.
    That is do 'channel' math rather than 'SVG' composition.

    With this change you can then use mathematical composition methods on
    individual channels or even with the alpha channel of images.

  * correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and
    'Distance' Morphology primatives. This does not have a performance hit,
    though is only truely applicable when the kernel is asymmetric.  Note that
    'Erode' does not use a 'reflected' kernel, so that 'Open' and 'Close'
    operations work properly.  This 'reflected usage is defined by online
    morphology lecture notes (Google for "EECE Binary Morphology")
  * Added convolve kernel scaling setting "-set option:convolve:scale N"
    If undefined morphology convolve does not do any scaling or normalization
    of the convolution kernel.  A value of 0.0 causes normalization for both
    zero and non-zero (added weights) kernel types.

2010-01-04  6.5.9-0 Anthony Thyssen <A.Thyssen@griffith...>
  * Added Kernel Generator to generate kernels from user strings, which
    allows the generation in many built in kernels for both Convolution
    and other Morphological methods.  New Kernels currently include..
      Convolution: Gaussian, Blur, Comet
      Morphological: Rectangle, Square, Diamond, Disk, Plus
      Distance: Chebyshev, Manhatten, Knight, Euclidean
    And both old and new (rectangular) user defined kernel specifications
    including the use of 'nan' to represent elements which are not part
    of the kernel definition.  List built-in kernel types use "-list kernel"
  * Added -morphology {method}[:{iteration}] {kernel_string}
    Initial methods includes no only the basic morphology methods: Dilate,
    Erode, Open, Close; and a pixel color preserving 'Intensity' version, but
    also the special methods: Convolve, and Distance.  Of course the
    appropriate kernel should be provided for each specific method.

  * Final testing and bug fixes for all mathematical compose methods
    Including non-overlapping regions bugs found in in operators Divide,
    ColorDodge,  VividLight.  And the handling of transparency to follow
    standard 'Over' Blending in Divide.  Only math methods not looked at are
    the addition methods Plus, Add, Minus, and Subtract, which do not follow
    normal 'Over' alpha blending behaviour, for the purposes of mask handling.

2009-07-12  6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
  * Addition of user definable 'Mathematics' compose method
      -compose Mathematics -set option:compose:args A,B,C,D -composite
    Will implement the formula    f(Sc,Dc) = A*Sc*Dc + B*Sc + C*Dc + D

    NOTE: 'LinearBurn' the same as 'Plus' but with the normal 'Over' blending.

2009-07-10  6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
  * Re-coding of Composite methods HardLight, SoftLight, Overlay, LinearLight,
    ColorBurn, ColorDodge, Multiply, Screen  to make it more readable, easier

    with a distortion 'center' to the middle of the overlay image
  * If a '%' flag given scale displacement relative to image size
  * If a '!' flag given make scale and center relative to 'background' image
    instead of the overlay map.
  * If no 'height' scale given, use the X scale.

  * Do not advance when finalizing image settings in the mogrify program.

2009-06-11  6.5.3-5 Anthony Thyssen <A.Thyssen@griffith...>
  * Fixed "convert" to merge the third 'mask' image into the 'source' image
    for correct handling of 2 dimensional -compose "displace".
  * Fixed PerlMagick Composite() for the same thing.
  * Modified compose "Displace" so displacement image's alpha channel can be
    used to mask the transparency of the overlay area.

2009-06-07  6.5.3-4 Anthony Thyssen <A.Thyssen@griffith...>
  * Changed CompositeImageChannel() so that extra compose arguments are
    now passed in the ImageArtifact "compose:args". This can be assigned to
    images using   -set "option:compose:args" 'args'  where args are defined
    using 'geometry' style or 'comma separated numbers'.
  * Declared the special flag needed for Composite Tiling as the ImageArtifact
    "compose:outside-overlay".

    background color.

2009-05-08  6.5.2-4 Cristy  <quetzlzacatenango@image...>
  * Combined layer of transparent PSD image was not being read properly.

2009-05-06  6.5.2-3 Glenn Randers-Pehrson <glennrp@image...>
  * Progress on "-define png:bit-depth=value" and "-define png:color-type=value"
    It is now able to write an opaque black-and-white image in any of the 15
    valid combinations of PNG color-type and bit-depth.
  * Fixed a regression with writing sub-8-bit grayscale PNGs.

2009-05-06  6.5.2-2 Chris Madison  <madisonblu@gmail...>
  * Create 8-bit TIFF images if -depth is set to 8 and HDRI-enable ImageMagick.

2009-05-04  6.5.2-1 Chris Madison  <madisonblu@gmail...>

    convert @- ...).
  * Duplicate line in tiff.c breaking read of zip compressed tif (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13688).

2009-05-01  6.5.2-0 Glenn Randers-Pehrson <glennrp@image...>
  * Accept "-define png:bit-depth=value" and "-define png:color-type=value"
    options.  This is work-in-progress with the objective of being able to
    precisely specify the type of PNG file to be written.  The previously-used
    internal attribute "png:bit-depth" that was used to communicate between
    the PNG writer and the JNG writer is changed to "png:bit-depth-written".
    This feature needs testing.  It is important to note that this feature
    cannot be used to force the PNG to use a bit-depth or color-type that
    does not losslessly represent the image.  You can, however, cause
    the writer to use a larger depth or to use the RGB colorspace when
    grayscale or indexed would have been sufficent.

2009-05-01  6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>
  * Fixed the Rmin usage in Depolar and Polar distortions
  * The 6th argument (Ato) for Polar/Depolar is now optional and defaults

  * Refrain from modifying image struct members (color, depth, matte)
    while writing PNG datastreams.

2009-04-21  6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
  * Sometimes the PNG8: format would produce 1-, 2-, or 4-bit PNG datastreams.
    Now it always produces 8-bit datastreams as users probably expect.

2009-04-21  6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
  * Suppressed "shadowed declaration" warnings in coders/jpeg.c and
    coders/png.c that are triggered by "-Wshadow" gcc compiler flag.

  * Rename existing "Bilinear" distortion as  "BilinearReverse"
  * Added forward mapped bilinear distort as  "BilinearForward"
  * The "Bilinear" distort is temporarily obsoleted but will eventually
    be added as a  "BilinearReverse" and "BilinearForward" combination
    mapping though a unit square.
  * Sparse Gradient internally uses "BilinearReverse" for its "Bilinear"
    gradient function as that method is the direct use of such equations.

2007-11-02  6.3.6-6 Cristy  <quetzlzacatenango@image...>
  * Upgrade to FPX version libfpx-1.2.0.14 (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10041).

2007-10-20  6.3.6-3 Anthony <anthony@griffith...>
  * Further expandsion and handling of filters with expert options.
    -filter selects from a table of standard filter settings, while
    expert options allow complete selection of filter, windowing, support
    and blurring options.  Includes automatic switch from Sinc to Bessel
    for operators using 2 dimentional cylindrical filter, rather than
    two pass 1 dimentional orthogonal filters.

2007-10-14  6.3.6-3 Cristy  <quetzlzacatenango@image...>
  * Obsolete -support (set filter blur factor)
  * Expandsion to add -set/define filter options

2007-10-12  6.3.6-2 Anthony <anthony@griffith...>
  * Least Squares coordinate handling added for -distort methods Affine,
    Perspective, Bilinear.   This allows for more than the minimal number of
    coordinates to be used to 'fit' a distortion function to an image.
    This addition will allow the use of image registration to generate
    panarama overviews and better geographical coordinate correction.
  * Cosolidated the simular methods FlattenImage() and MosaicImage()
    into a new layers function MergeImageLayers() method, adding 'flatten'
    and 'mosaic' layer methods.
  * Addition of another simular layers method 'merge' which 'unlocks' the
    normal flatten/mosaic layer merger from the origin, The resulting image
    will have a virtual canvas of minimal size with an offset. Also images
    with negative offsets will not be clipped by the 'merge' form of the
    command.  This was created for better layering of distorted images, such
    as panarama overlays.
  * Bug fix in handling transparency for EWA resampling.
  * Access to Resize Filter Functions from resize.c (for resample.c)
    with posible future filter sources... Acquire/Destory/Call ResizeFilter()

        image.pdf[1-3]).
  * Detect proper PDF bounding box when offsets are negative.

2007-10-02  6.3.6-1 Cristy  <quetzlzacatenango@image...>
  * Speed up the Fx interpreter.
  * Use ULL not ui64 for MinGW 64-bit constants.

          file as required under Windows.

2007-09-29  6.3.6-0 Anthony <anthony@griffith...>
  * Added Scaling 'derivitives' to -distort Arc, so image arcing is now
    sharp and clear as you approach the center of the distort.
  * Added  " -set option:distort:viewport 'geometry' " special option
    that can be used to override the output image size and offset.
  * Fixed experimental use of -filter and -support in Resampling (more later).
  * Changed order for coordinate arguments in -distort (for later leastsq
    multiple coordinate distortion function fitting)

2007-09-22  6.3.6-0 Cristy  <quetzlzacatenango@image...>
  * Check the API version and quantum depth before loading a coder module or
          image filter (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780).
  * Add exception to the image filter signature.
  * Get the execution path under Mac OS X.
  * TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c).
  * Fixed memory leak in CloneString() (reference
    http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763).
  * Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in
    CopyDelegateFile().

2007-09-18  6.3.5-9 Anthony <anthony@griffith...>

    a 64-bit FreeBSD system.
  * The -level option now works properly for colormapped images.
  * Allow Extrapolated blending of images using -blend
       http://netpbm.sourceforge.net/doc/extendedopacity.html

2007-09-12  6.3.5-9 Anthony <anthony@griffith...>
  * Major Addition,  Area Resampling Functions, (scaled interpolation)
    for pixel lookup in Distortion functions.  This improves the look in
    areas of minification enormousally, especially in situations of infinite
    tiling and horizon views.  All virtual pixel methods have been handled
    to minimise computation time involved with area resampling.  To use the
    new function distortions need to be able to determine scaling vectors
    (distortion function derivitives) for correct working.  All
    -distort methods, except Arc, uses scaled area resampling.
  * Improvements to perspective distort method, to include the correct
    differentation between the 'ground' on which the image lies, and the
    'sky', the color of which can be set using the -mattecolor setting
    (as the distortion invalid pixel color). Background color is retains
    for surrounding ground areas. The horizon is also correct anti-aliased
    and transparent colors are also allowed, allowing you to add backdrops
    of gradients and patterns.
