Hi Alex, Yes, I've seen that approach... but what I mean is really smearing, trailing pixels along at various intensity blurring out the ones at the end or something like that. I'll try the copypixel thing, and see what it gives. I'll get back on this.

First thing to try is to use quads with copyPixels and leave "the magic" to Werner Sharps IL code, using the undocumented #dither parameter with the value 1969 for antialiasing, instead of going through each pixel with very slow get- and setPixel() something like this: <http://www.farbflash.de/cgi-bin/blosxom.cgi/Dokumente/Director/ Opensource/Imaging/goo.html> this can be optimized by dividing the image in more than only 4 quadrants, like in the example, so that you achieve a given radius of affection. --------------------------- ||| a¿ex [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/lingo-l.cgi To post messages to the list, email [email protected] (Problems, email [EMAIL PROTECTED]).
