Or copypixel with a mask image, like a soft PS brush?

Hi,
Can't the blendlevel in the copypixel's parameterlist be a variable?
Doesn't seem so...

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.

Hi,
While we’re still on the subject, anyone has suggestions on the
approach to a mouse-dragging-driven smear effect?
Maybe copypixelling a small region around the cursor, do some
pixelpushing on that, and copy it back with a < 100% blend?
Main concern here would of course be performance... I've seen some
nice things in flash using displacement maps...
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:

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.
