Thanks for your responses. It does look as though PIL might be what I'd use if I had a choice ... Tk support is a big plus ... but I am sort of stuck with Perl/Tk. I was hoping to use the functions in ImageMagick (crop, annotate text, blur, add noise, scale, rotate, circlur crop). I guess I would have to write the image out to disk everytime a manipuation to it was made ... and then read it back in a display it via Tk's photoimage method. :/ Again thanks for your responses so far!
