This is the effect of pasting a flame fractal from Apophysis 2 into Ultrafractal 3.05. In UF3, I can remove the background to make a transparent graphic. In this case, however, the background was black and some of the fractal was black. Removing the black background doesn't remove the fractal part. I modified the fractal with one of my gradient files, also. In UF3, it is possible to further adjust the gradient. Setting transparent areas within the gradient file, etc. Once I have removed the background, I can draw shapes in X1. Eight legs, it had to be a spider. Apo is freeware.
