Funny, I was wondering about alternatives too! I'm trying to work out in my mind these different visual effects: Assume we have two gradients, with the same number of stops in the same positions. a) Interpolate the colors at each stop, and then generate a gradient based on the interpolated colors. b) generate the two gradients, and cross-fade them c) generate the two gradients, and then define an image transition effect 'color-interpolate' where each pixel is interpolated between its starting and ending colors On Apr 19, 2010, at 11:56 , L.
