Indeed. Anytime you want to do anything via command line with bitmapped graphics, the first place you look is Imagemagick: http://www.imagemagick.org/Usage/quantize/ Or more specifically http://www.imagemagick.org/Usage/quantize/#monochrome If you don't find what you want in Imagemagick, the second place you look is Imagemagick -- it's probably there and you missed it the first time. -- Grant Edwards grant.b.edwards Yow!
