美国慈善家、乔布斯的遗孀劳伦 · 鲍威尔 · 乔布斯，为整部文集写了一则非常具有智慧和启发性的引言，其中她提到了里尔克的一个金句：
Instead of perturbing each pixel in the input image at random, we can choose to dither by a predetermined amount depending on the pixel’s position in the image. This can be achieved using a threshold map; a small, fixed-size matrix where each entry tells us the amount by which to perturb the input value , producing the dithered value . This matrix is tiled across the input image and sampled for every pixel during the dithering process. The following describes a dithering function for a 4×4 matrix given the pixel raster coordinates :
