ÂIs there a good way to do this? There is no official way to do that for script-fu or automatically-generated interface python-fu scripts (appart from asking the user to type each coordinate, of course). However, in my experience a good way to achieve coordinate input for *-fu scripts is asking the user to draw a path (vector) on the image, and using the first N control points of said path as the needed coordinates. You can use the vectors pdb functions to read those coordinates. regards, js -><- > > Thanks, > > Rob > > > > ------------------------------------ > > Yahoo! Groups Links > > > >
