Did you know?
Ordered dithering is an image dithering algorithm. It is commonly used to display a continuous image on a display of smaller color depth. For example, Microsoft Windows uses it in 16-color graphics modes. The algorithm is characterized by noticeable crosshatch patterns in the result. See more The algorithm reduces the number of colors by applying a threshold map M to the pixels displayed, causing some pixels to change color, depending on the distance of the original color from the available color … See more The above thresholding matrix approach describes the Bayer family of ordered dithering algorithms. A number of other algorithms are also known; they generally involve changes in … See more • Matlab implementation of various dithering methods • anim8gdx, Java implementation of various (mostly ordered) dithering methods See more The ordered dithering algorithm renders the image normally, but for each pixel, it offsets its color value with a corresponding value from the threshold map according to its location, causing the pixel's value to be quantized to a different color if it exceeds … See more • Ancin, Hakan; Bhattacharjya, Anoop K.; Shu, Joseph S.

That means that your algorithm should only read from Floyd, not from image or pic. And Floyd should be a copy of pic, the original image.
