2010-05-07 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...># 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.2010-05-06 6.6.1-6 Cristy <quetzlzacatenango@image...># 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.2010-05-06 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...># 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.2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...># Fixed bugs with losing the opacity channel while writing some PNG images. (bug reported by Anthony T.)2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...># Simplified and corrected rowbytes calculation in coders/png.c and added more logging.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 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.2010-04-28 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...># Special case handling in Barrel distortion (pixel at image center)# Calculation of image for Barrel distortion (pixel vs image coords)# Argument input (handling optional 'd' argument) for Barrel distortion2010-04-24 6.6.1-6 Cristy <quetzlzacatenango@image...># Do not declare timestruct under MinGW.# Respect -compose option for the montage utility (bug report by Anthony).# A 256 column gradient produces a 256 color GIF image (bug report by Anthony).# Register / unregister CALS format in static.c (reference http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=16103).# Add SetImageColor() method.
