Ordered dithering python
WebOrdered dithering does not need float-point arythmetic. It can be achieved in purely integer computations. Also it is good to pre-calculate the values in the matrix. Here is a code in C that performs 3bpp ordered diter (Bayer) with matrix 16x16 for best result. const int BAYER_PATTERN_16X16 [16] [16] = { // 16x16 Bayer Dithering Matrix.
