WebTo do the opposite of dithering, you can usually just scale the image down and then back up again with pamscale, possibly smoothing or blurring the result with pnmsmooth or pnmconvol. Or use the special case program pbmtopgm. To dither a color image (to reduce the number of pixel colors), use ppmdither. Another way to convert a grayscale image ... WebNov 11, 2011 · Stochastic screening uses synthetic random patterns in stead of matrices to represent shading in the inks. A kind of instant-dithering within the matrix of printer dots, resulting in less apparent banding at the same numbers.
