  New version 6.7.6-8, SVN revision 7705.
2012-04-25 6.7.6-8 Anthony Thyssen <A.Thyssen@griffith...>
  Gaussian Filter Fixed. For some strange reason it was half the width it should be with an effective sigma of 0.25 (not 0.5). This was the real reason "variable blur" was not blurring enough.

  Allow +-X+-Y as geometry arguments.
2012-04-17 6.7.6-7 Cristy <quetzlzacatenango@image...>

  New version 6.7.6-6, SVN revision 7536.
2012-04-11 6.7.6-6 Glenn Randers-Pehrson <glennrp@image...>
  Always unlock the semaphore before returning from the png codec, either by a "return" or png_error(); changed all Magick*Exception() calls after setjmp() to png_error() to ensure proper cleanup (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=16883).
2012-04-10 6.7.6-6 Anthony Thyssen <A.Thyssen@griffith...>
  Fixed log known alpha*kernel normalization bug in morphology convolve.
Convolve kernel weights have been separated from alpha blend handling. Un-normalized kernels applied to images with active alpha will no longer be auto-normalized due to the effect of alpha blending. The bug causes images using the default channel setting and having an alpha channel to automatically 'normalize' the results of a convolve during the handling of alpha blending. This probably would cause severe effects when a zero-summing kernel is being used on an image containing an active (though likely fully-opaque) alpha channel, as division by near zero weights would cause extreme color values in results. This bug is not normally seen as convolution, which is normally applied only to fully-opaque images. And using a zero-summing kernel on an image with alpha also results in a transparent image! This is why it was not fixed up until now.
2012-04-08 6.7.6-6 Cristy <quetzlzacatenango@image...>
  Pixel allocation for Pango is stride*rows not stride*columns.
  Set the image resolution for Postscript files with an embedded Photoshop profile.

  Add signal handler for SIGBUS.
2011-04-15 6.6.9-5 Cristy <quetzlzacatenango@image...>
  New version 6.6.9-5.
2011-04-15 6.6.9-5 Glenn Randers-Pehrson <glennrp@image...>
  Added "#define PNG_PTR_NORETURN" because this macro does not work on all platforms with libpng15, with failure to load png_longjmp() (ref http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=18518).
2011-04-14 6.6.9-5 Anthony Thyssen <A.Thyssen@griffith...>
  Layers Composition Bug Fix, animations attributes of first image not transferred in a single destination, multi-source image composition.
2011-04-09 6.6.9-5 Anthony Thyssen <A.Thyssen@griffith...>
  Add a special 'Voronoi' Morphology Distance method that will fill in holes using the nearest non-transparent edge pixel. It is experimental, and hidden from normal morphology usage, as it may be interfaced with a future hole-filling color 'Diffusion' method.
2011-04-08 6.6.9-5 Cristy <quetzlzacatenango@image...>
  MIFF keywords sometimes includes spaces.
2011-04-07 6.6.9-5 Anthony Thyssen <A.Thyssen@griffith...>
  Major BUG FIX - wrong sign breaks most morphology methods in IM v6.6.9-4
  Fixed -region handling of transparency. Original images without transparency will use 'Over' while images with transparency will preserve transparency using 'Copy'. Before this only 'Over' was used due to the testing of the wrong image.
  Added Compose methods DarkenIntensity and LightenIntensity
2011-04-06 6.6.9-4 Cristy <quetzlzacatenango@image...>
  New version 6.6.9-4.
2011-04-03 6.6.9-4 Anthony Thyssen <A.Thyssen@griffith...>
  Add Octagon shape and Octagonal distance kernels for Morphology
  Fix minor Morphology kernel compose bug (cleanup after Src/Dst swap)
  Fix segmentation fault after error in a morphology 'named' kernel
  Added a range of kernels used for specialised thinning purposes as defined in a research paper by Dan S. Bloomberg.
  Added Dan Bloomberg best thinning skeleton, "Skeleton:3"
  Removed origin pixel from many Hit-and-Miss kernels allowing kernels to not only be used for thinning, but also thickening.
  Renamed "ThinDiagonals" kernel to just "Diagonals"
  Distance uses a fast two pass algorithm, and no longer needs 'iteration'
2011-04-02 6.6.9-4 Glenn Randers-Pehrson <glennrp@image...>
  Make the PNG encoder use depth==8 when incoming image->depth < 8 (the encoder later reduces the depth if it can), to avoid writing an incorrect image.
  Remove any bogus colormap received by the PNG encoder with an image that is not PseudoClass (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=18475).
2011-04-02 6.6.9-3 Cristy <quetzlzacatenango@image...>
  Added -statistic Gradient
2011-04-01 6.6.9-3 Cristy <quetzlzacatenango@image...>
  New version 6.6.9-3.
2011-04-01 6.6.9-3 Cristy <quetzlzacatenango@image...>
  Set the caption height correctly for missing row geometry (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=18447).
2011-03-31 6.6.9-2 Cristy <quetzlzacatenango@image...>
  New version 6.6.9-2.
2011-03-30 6.6.9-2 Glenn Randers-Pehrson <glennrp@image...>
  Revised the png decoder to store the PNG IHDR and other known PNG chunk data as properties, for later retrieval and reporting by "identify", so users can easily and reliably discover the color-type, bit-depth, etc that were in the input PNG datastream.
  The PNG decoder sometimes set images with more than 256 different gray-alpha pixels to storage_class=PseudoClass with an incorrect colormap.
2011-03-30 6.6.9-2 Anthony Thyssen <A.Thyssen@griffith...>
  Add a "Resize" distortion method (distort equivalent of -resize).
  Special CLI handling so -distort Resize takes a "geometry" argument.
2011-03-29 6.6.9-2 Cristy <quetzlzacatenango@image...>
  Expand PCL compressed pixel buffer to prevent delta compressed overrun.
2011-03-29 6.6.9-1 Cristy <quetzlzacatenango@image...>
  New version 6.6.9-1.
2011-03-29 6.6.9-1 Anthony Thyssen <A.Thyssen@griffith...>
  Fix AdaptiveResizeImage() to use 'Mesh' Interpolation, and fix its coordinate handling, as originally defined.
2011-03-29 6.6.9-1 Cristy <quetzlzacatenango@image...>
  Support -statistic standard-deviation option.
  Patch for coders/dcm.c so it compiled with HDRI enabled.
2011-03-28 6.6.9-0 Cristy <quetzlzacatenango@image...>
  New version 6.6.9-0.
2011-03-28 6.6.9-0 Cristy <quetzlzacatenango@image...>
  Optimize bilinear interpolation.
  Remove version from etc folder and instead use /etc/ImageMagick.
2011-03-28 6.6.9-0 Anthony Thyssen <A.Thyssen@griffith...>
  Separated complex cropping function from TransformImage() as a new function CropImageToTiles(). This new function returns either the new cropped image, or a list of tiles, according to geometry, without replacing the source image. The Source image may be part of a larger list of images, without the function 'losing' the other images of the list.
2011-03-27 6.6.8-0 Cristy <quetzlzacatenango@image...>
  New version 6.6.8-0.
2011-03-27 6.6.8-0 Anthony Thyssen <A.Thyssen@griffith...>
  Modified image handling in MogrifyImages() and MogrifyImage() which improves overall handling, and allows correct %p, %n and the %[fx:..] 't' and 'n' escape usage to work correctly.
  Added -duplicate as a multi-image sequence operator
2011-03-26 6.6.8-9 Cristy <quetzlzacatenango@image...>
  New version 6.6.8-9.
2011-03-25 6.6.8-9 Cristy <quetzlzacatenango@image...>

  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.html?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.html?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
  Finalize 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 4-4-4-1 and 3-3-3-1 palettes instead of 3-3-2-1, 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.html?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.html?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.html?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.html?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.html?f=3&t=17086 and http://www.imagemagick.org/discourse-server/viewtopic.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?f=3&t=17623).
  Add -smush option (reference http://www.imagemagick.org/discourse-server/viewtopic.html?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.html?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.html?f=3&t=17890).
  Eliminate fault when reading WMF image files (reference http://www.imagemagick.org/discourse-server/viewtopic.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?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.html?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

  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.html?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...>

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.html?f=3&t=17246).

  Replaced "Robidoux" with Cubic 'Keys' filter that is near equivalent to the previous sharped "Lanczos2D" filter. (C=0.31089212245300069) This also is very similar 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..>

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-aliasing for output-scaled perspective distortions.
  'Bessel' filter is now officially and more accurately 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.html?f=2&t=15960).

  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.

2010-09-24 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.html?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)

  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...>

  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 comparison 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.

  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

  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

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.

  added use of -precision in 'showkernel' output of -morphology
  correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and 'Distance' Morphology primitives. 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.

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 sufficient.
2009-05-01 6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>

  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.

  Expansion 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 panorama overviews and better geographical coordinate correction.
  Consolidated the similar methods FlattenImage() and MosaicImage() into a new layers function MergeImageLayers() method, adding 'flatten' and 'mosaic' layer methods.
  Addition of another similar 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 panorama overlays.
  Bug fix in handling transparency for EWA resampling.
  Access to Resize Filter Functions from resize.c (for resample.c) with possible future filter sources... Acquire/Destory/Call ResizeFilter()

  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 enormously, 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 differentiation 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.
