Σχήμα 17.344. Example for the Bayer Matrix filter

«Bayer Matrix» filter applied with Scale X, Y = 20

A grand-sounding name for a simple filter. Bayer matrix is related to ordered dithering, which is an image dithering algorithm used to display a continuous image on a display of smaller color depth. The algorithm reduces the number of colors by applying a threshold map known as Bayer matrix (Wikipedia). The present filter uses the Bayer matrix only to create a pattern.

You can find this filter in the image menu through Filters → Render → Pattern → Bayer Matrix…
