Gif maximum can only be 256, can't increase the number of colors, hope to increase jitter processing to optimize the image effect. #65

Hi, the GIF format is limited to 256 colors. How exactly can I help you?

UPNG.quantize(data, psize) add dithering

Have you thought about using JPG or PNG instead? These formats support more colors and are usually smaller than the GIF file.

Because the project can only use GIF.

GIF.js has dithering.
