Interesting.... I'm really workign on a dynamic system though, enter data into form and image is generated. I wonder if those steps would be a bit rough that way.. I don't know, I'll look into it for sure. Actually I guess I could do Tk::canvas save it to a temp .ps file and open the tmep file with GD or Imager or somethgin and conevrt it on the fly I guess it's not too impossible after all, I'll add this to my list of trick to try.
