2009-05-02 6.5.2-0 Chris Madison <madisonblu@gmail...>

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.imagemagick.org/discourse-server/viewtopic.html?f=1&t=13671).

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 to Afrom + 360 degrees (or a fill circle from the given start angle)

2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>

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()

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.
