Yes, I've seen several (although I must admit that it's been some months since I last looked), but none that produced the nice results I want. I also want a prog that can calculate large images (I'm talking about one or more square meters at the printer's resolution), not that I have the disk space and lots of spare CPU time (three fast dual processor machines that mostly idles...). I thought that someone could recommend a prog worth trying, sparing me the effort of sifting through dozens of progs that's not up to the task. /Troberg
