how to get color palette about omggif HOT 5 CLOSED

Yes, the way that the GIF format is specified it is max 8-bit (256 color) indexed color. The palette is supplied in the GIF, so you must also supply it to omggif.

There are many different color reduction / quantization algorithms that you can use for choosing a palette. This is really independent of omggif / gif encoding. I don't think there should be any problem using the above NeuQuant code w/ omggif, for example. Additionally you may also want to do dither, which is normally another independent pass.

When I have some more time I planned on working on dithering / color quantization (for example spatial color quantization and other algorithms). This would be a separate project from omggif, but I realize it would be helpful here too...

I had some fun figuring out some monochome dithering in JS (live, code) but the color stuff seems beyond me for now.

If you're going to monochrome 256 colors, there is no reason to dither.

For anybody interested, here is OMGGIF working with NeuQuant.js in a worker: https://github.com/meemoo/iframework/blob/master/libs/omggif/omggif-worker.js
