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 :
Over time, it evolved into a universal reaction image, a shorthand for anyone who had missed the moment entirely. You didn't need to know Slowpoke's Pokédex stats to understand it. You just needed to know what it felt like to realize something after everyone else already had.
