Then the solution is simple, if not then you need something like multi-replace. First convert the image to greyscale, and normalize it to maximised the color gradient. Do not use -normalize as it has some clipping add for handling JPEG images.... -colorspace gray -contrast-stretch 0 See http://imagemagick.org/Usage/color/#grayscale http://imagemagick.org/Usage/color/#contrast-stretch You could also extract a color channel, and normalize (stretch) that image... http://imagemagick.org/Usage/channels/#separate now use either color gradient replacement or a mathematically re-coloring method. Lots of these are shown in IM examples, Color Modifications http://imagemagick.org/Usage/color/ Alturnativally have two images of the colors (or pattern) wanted for each end of the gradient, and use the normalized image as a mask using a three image composite... http://imagemagick.org/Usage/compose/#mask Anthony Thyssen ( System Programmer ) <[EMAIL PROTECTED]> ----------------------------------------------------------------------------- "Oh, the pain... the pain of it all!" -- Doctor Smith, Lost in Space ----------------------------------------------------------------------------- Anthony's Home is his Castle http://www.cit.gu.edu.au/~anthony/ _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
