WebApr 19, 2024 · Ordered dithering is a technique used to reduce - deliberately! - the precision of an image. the value x between a and b - that should be grayish - is simulated by mixing pixels of colors a and b. To apply some ordered dithering on an image, we apply the same logic but in 2D by using a bayer matrix. WebOct 3, 2024 · the dither should be a counted as a flag, ie; flags=lanczos and use dither method with bayer_scale. I don't get why this isn't working anymore when it worked before.
