One way of minimizing the size of an image is to simply reduce the number of bits you use to represent each pixel. by default this number is 24 bits for RGB representation. You can reduce this number by quantization and reduce it to 1 bit (black or white). However this has its downside which is known as banding effect ... WebThe Dither extension method is the starting point for dithering a Bitmap in-place, and here are the OrderedDitherer constructor, the strength calibration for the min/max values of the matrix and a fairly fast nearest color search either by RGB channels or by brightness.

WebMay 3, 2024 · + Ordered dithering. It divides an image into several patches with the size of m×n pixels. Each pixel in one patch no longer compares to a fixed threshold (as used in averaging dithering) but a corresponding value defined in the threshold map (or called matrix). Take the M2 map as an example. WebOrdered dithering is, how I see it, the process by which an ordered pattern of colors is applied to an image to create the illusion of a higher color depth when colors are limited. …
