Added new operator +/-level-colors which will 'level' images based on colors to use for the black and white points. This lets to adjust the image in terms of mapping the given colors from/to black and white respectivally.

2008-06-23 6.4.2-0 Christian Lackas <christian@lacka...>

Fix a problem with calling mpeg2encode with parameters (%o/%i) in wrong order.

2008-06-18 6.4.1-9 Anthony <anthony@griffith...>

Added a LevelizeImageChannels() which is simular to LevelImageChannels() Function maps black and white values to the given level values. Rather than mapping the given level values to black and white. Bacically a 'reverse-level' function, with different input args.
Set +level or a '!' flag in -level or LevelImage() to call the new 'reverse-level' function LevelizeImageChannels().
More work on IsMagickColorSimular() to fix relationship between transparent-black and opaque-black, which was matched as 'simular'. Also attempts to fix 'K' channel handling for CMYK colorspace. More work on this to come.

Instead of masking the PNG tRNS values when reducing from 16-bit, set image->matte to MagickFalse and emit a warning. This will produce behavior similar to that of libpng-1.2.27 (and libpng-1.2.19 and earlier).

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()
All resize filters added to resampling, but filter handling is incomplete.

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).

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.
