Frequently asked questions

What is Floyd–Steinberg dithering?

It spreads each pixel's rounding error to its neighbours, which gives smooth, natural-looking tones from only two colours.

Can I get the crosshatch style instead?

Yes. Choose Ordered 4×4 or 8×8 for the regular pattern used in older games and printing.

Will it work for printing?

Yes. Use a small pixel size so the dots stay fine at print resolution.
