oh wise list,

We have a low res image that we apply color transformations in AS3/Flash - and want to re-create the same color transformations in IM

the workflow process is : http://cl.ly/24371N3f0g0W041R380f

is this possible?
if so, i would like to hire you!

thanks

please clarify color transformations in AS3/Flash? We all do not use Flash. If you are referring to something like this http://www.adobetutorialz.com/articles/ ... lor-Matrix, then see -color-matrix in IM http://www.imagemagick.org/script/comma ... lor-matrix

I dont think ColorMatrix will work for replacing colors - therefore ColorTransform should.
here is some info : http://asgamer.com/2011/changing-colors ... n-as3-code

here is the class definition:

thanks!

see -CDL (color decision list), where you can specify a slope (multiplier) and offset (and optional gamma) for each r,g,b,a channel

http://www.imagemagick.org/script/comma ... ns.php#cdl

Otherwise, you can change colors by optionally specifying a fuzz value (color distance) and then an old color (-opaque) and a new color (-fill)

convert image -fuzz XX% -fill red -opaque blue result

see
http://www.imagemagick.org/Usage/color_basics/#replace


Or you can flood fill a region with a color (using and optional fuzz value).
