Dear developers. I thank all of you for quick reply to my questions. "fu" is from "kung-fu", which I never come to think of it. But now I see very well that a master of "something-fu" can wear a black belt. > http://film.gimp.org/ Thank you also for let me know about this project. I never minded about plug-ins. Now I see this is really a hard work... regards. FUJITA Yuji yuji@xxxxxxxxxxxxxxxxxx http://www.wl.me.titech.ac.jp/~yuji/yuji-pubkey.asc
