I've posted the siod documentation that I use on my website at http://trefftzs.topcities.com/siod.html It also shows functions that are not available in the Gimp, but fewer than your source. I seem to remember that I had to roll my own floor, ceil, and round functions. Good luck. -- --Jeff Jeff Trefftzs <trefftzs@xxxxxxxx> http://www.tcsn.net/trefftzs Home Page http://gug.sunsite.dk/gallery.php?artist=68 Gimp Gallery http://trefftzs.topcities.com/ Photo Gallery
