Hi all, Perl+ImageMagick can still do this (use Image::Magick). Attached is a *very* dirty hack that I used to threshold an image according to my own strange criteria. It actually creates a new black & white image and sets each pixel individually within that image. So that's how you can set a pixel... I'm doing it based on the data in another image but there's no reason why you couldn't do it from your own data. This, perhaps, is a useful example for you. good luck! Stuart PS in the example you can see that I've used xc: and png: to specify the file type, but I think there's also a raw: type that you might be able to use. YMMV. -- Stuart Prescott www.nanoNANOnano.net
