WebThe demo also does halftone dithering and Bayer dithering (just 2 bit) which don't use error-diffusion, which for these two makes the patterns evident that error-diffusion usually lessens. This runs completely client-side, using the FileReader and canvas APIs. If you have a somewhat modern browser, this should work. WebFloyd–Steinberg dithering is an image dithering algorithm first published in 1976 by Robert W. Floyd and Louis Steinberg.

WebJun 7, 2011 · Digital halftoning is the process of converting a continuous-tone images into strictly black and white images such that, when viewed by the human visual system, the pattern creates an illusion of being a continuous shade of gray. The binary image created by halftoning is used in binary display devices, such as desktop inkjet printers. WebHalftone Pattern The machine can use two methods ( Diffusion or Dither ) to arrange dots to express halftones. There are some predefined patterns and you can choose which …
