• Rename existing "Bilinear" distortion as "BilinearReverse"
• Added forward mapped bilinear distort as "BilinearForward"
• The "Bilinear" distort is temporarilly 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.

• The mogrify -crop option returns multiple images if an x/y offset is not specified (e.g. -crop 100x100).
• Generate a proper file path for -path @filelist.txt (reference http://www.imagemagic...p?f=1&t=13671).
• Accept "-define png:bit-depth" and "-define png:color-type" 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 to use the RGB colorspace when grayscale or indexed would have been sufficent.

• Support heterogeneous distributed processing, see http://www.imagemagic...hp#distributed.
• Fix semaphore assertion when reading a corrupt image with Magick++.
• Add support for -brightness-contrast option.
• Add support for the BGRA raw image format.
• 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: Dialate, 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.

• added use of -precision in 'showkernel' output of -morphology
• 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.
• Speed up reading the PSD image format.
• Add the -precision option. Use it to set the maximum number of significant digits to be printed.
• Add -features option to the identify program to display channel features.

# Added % and ! modification flags to morphology distance kernel scaling factor.
# Bug fix for compose math channel handling and morphology diff usage
# The -list option returns a 0 status as expected.
# 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 reound rectangles.
# Made use of new no-'sync' channel enabled mathematical compose methods for the difference morphology methods. These should now work correctly for specific channels, and more importantally for alpha shaped morphology.
# Fixed bugs with losing the opacity channel while writing some PNG images. (bug reported by Anthony T.)
# Simplified and corrected rowbytes calculation in coders/png.c and added more logging.
# 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 defintion 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 syncronized 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 syncronization 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.

# Rename of SincPolynomial to SincFast for easier user understanding
# Ditto for LanczosChebyshev to LanzcosFast
# Switch default resize filters to using the faster SincPolynomial filter by default internally. However 'Sinc' will stil use the Trigonometric function, and can be used to assign the trig version of Sinc() to filters using the filter expert options.
# Removed the default filter for 'distort' was found to be a very blurry inaccurate filter function. It was removed and replaced with a correct Gussian 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. It is slightly slower though. 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 switched 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.

# Affine multiplication reversed when translating (reference http://www.imagemagic...p?f=3&t=17570).
# Revised the "c7x7b" and "c7x7w" ordered-dither maps to be complementary to each other.
# Add support for -evaluate-sequence median.
# Fixed two more cases where the PNG encoder lost transparency (reference
http://www.imagemagic...p?f=3&t=17516).
#
2010-11-23 6.6.6-0 Cristy
# 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.

# 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.
# Account for virtual canvas for the -flip / -flop options (reference http://www.imagemagic...p?f=1&t=17626).
# Ordered Dithered handling of Alpha channel was incorrect - fixing Bug was introduced v6.6.5-6

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.imagemagic...p?f=3&t=17655). Eliminated CompressColormapTransFirst() since the palette is already compressed and sorted by opacty now when it's recreated.
Account for virtual canvas for the -flip / -flop options (reference http://www.imagemagic...p?f=1&t=17626).
Also for -transpose and transverse options
Support -metric fuzz option.

# Handle negative heights for ICO images.
# 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.
# 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.imagemagic...p?f=3&t=17748)
# -posterize fails with more than 40 levels (reference http://www.imagemagic...p?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.
# 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.
# Removed the forced interpolation setting in AcquireResampleFilterThreadSet It prevented user defined interpolation settings for -clut, and possibly other usage.
# Add LZMA compression support to ImageMagick.
# 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.
# -format "%[fx:u.p{5,5}]" no longer reports parse exception (reference http://www.imagemagic...p?f=3&t=17678).
