fern :: IFS Double Source

Example of use

Generating the fractal for the Sierpinski IFS:

 createPict "essai.ppm" 600 600 1.0 200000 (binaryColor white blue) sierpinski

Combining square and sierpinski:

 createPict "essai.ppm" 600 600 1.0 200000 (binaryColor white blue) (0.5 <?> square <+> 0.5 <?> sierpinski)
