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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
