RMagick is an interface between the Ruby programming language and the ImageMagick and GraphicsMagick image processing libraries.
require 'RMagick' clown = Magick::ImageList.new("clown.jpg") clown = clown.wave(10, 200) clown.write('wave.jpg')
require 'RMagick' clown = Magick::ImageList.new("clown.jpg") clown = clown.quantize(256, Magick::GRAYColorspace) clown.write('monochrome.jpg')
