object floyd_steinberg()
object floyd_steinberg(int bidir, int|float forward, int|float downforward, int|float down, int|float downback, int|float factor)- Description
-
Set dithering method to floyd_steinberg.
The arguments to this method is for fine-tuning of the algorithm (for computer graphics wizards).
original floyd_steinberg to a 4×4×4 colorcube floyd_steinberg to 16 chosen colors - Parameter bidir
-
Set algorithm direction of forward. -1 is backward, 1 is forward, 0 for toggle of direction each line (default).
- Parameter forward
- Parameter downforward
- Parameter down
- Parameter downback
-
Set error correction directions. Default is forward=7, downforward=1, down=5, downback=3.
- Parameter factor
-
Error keeping factor. Error will increase if more than 1.0 and decrease if less than 1.0. A value of 0.0 will cancel any dither effects. Default is 0.95.
