Floyd–Steinberg dithering is an image dithering algorithm first published in 1976 by Robert W. Floyd and Louis Steinberg. It is commonly used by image manipulation software, for example when an image is converted into GIF format that is restricted to a maximum of 256 colors. See more The algorithm achieves dithering using error diffusion, meaning it pushes (adds) the residual quantization error of a pixel onto its neighboring pixels, to be dealt with later. It spreads the debt out according to the distribution … See more • Atkinson dithering, a variant of Floyd-Steinberg dithering designed by Bill Atkinson See more WebJun 15, 2015 · In my previous introductory post, I briefly described the concept of dithering an image.

It scans the image one pixel at a time, scanning the top line from left to right, then the next line, etc. until it reaches the bottom. For a bitonal dither, it's easier if we first convert the whole image to grayscale, so that each pixel has a luminosity (perceived brightness) value of 0 to 255. http://xinyuefei.com/uncategorized/floyd-steinberg-dithering.html how to show a line break in poetry
