E-Paper Floyd-Steinberg

Instroduction

Floyd-Steinberg dithering algorithm is suitable to show a rich sense of gradation based on a picture that has few colors. This makes it possible to obtain more color combinations and perform better shadow rendering on the original picture, especially suitable for e-Paper display.
This instruction we will show you how to made Floyd-Steinberg image
You can also refer to the demo codes of ESP32 or ESP8266 about the realization of the Floyd-Steinberg algorithm.

Create a new Photoshop project, and set the resolution according to the e-Paper you use, set the color mode to RGB. For example, we use 7.5inch e-Paper whose resolution is 800*480 as example.
