Halftone
Blue noise
Blue-noise dithering — no regular grid, and none of the diffusion worms.
Controls
- levels
- Two levels is bare ink and paper. More puts a tonal ladder between them and the grain thins out
- contrast
- A number from -1 to 1, 0 by default.
- tile
- The mask repeats every this many pixels. The larger tile hides that repeat on a big frame and costs a pause on each new seed
- ink
- A colour, #ffffff by default.
- paper
- A colour, #000000 by default.
