That might not have the desired effect. It ' s a 4 liner scripfu -or python -fu that would slice the image in rectangular selections and run the filter variably on these rectangles what he is needing. I made such a filter in python fu once, and I'd paste it here, if I had it. I did it with the pixelize filter, all one have to do is to change the filter used. It is in the script-fu list in yahoo.com archives, however. - The person taht was needing it did not had pythofu working, so I posted it there for someone to translate it into scriptfu (I have too many things to do rather than trying to figure Scheme out) /me googles for "gwidion script pixelize gradient" and clicks on first result. /me pastes result here. (I will remove the ">>" from the scripts for them to work., If you settle for the python one, beware of the spacing. On Monday 17 November 2003 06:12, [EMAIL PROTECTED] > wrote: > > Here you are.
