This filter transforms the image with the Mandelbrot fractal: it maps
the image to the fractal.
You get to this filter via the Image menu through
“Fractal trace” filter options
X1, X2, Y1, Y2, Depth
These parameters are similar to X/YMIN, X/YMAX and ITER
parameters of the Fractal Explorer
filter. They allow you to vary fractal spreading and detail
Mapping image to fractal may reveal empty areas. You can select
to fill them with Black,
White, Transparency or
make what disappears on one side reappear on the opposite side
with Wrap option.
