QOIR: A fast, simple, lossless image file format

  5 244 2.0 Go

  Build a simple video encoder from scratch

> For example, if you have a relatively wimpy camera that streams out a 160×120 grayscale image, it might be fun to see how far you can push something like combining:

I'm typically not one for self-promo but I did this with video and you can get 90% compression with exactly those three basic steps. RGB -> YUV420, delta encoding, then basically-upgraded-RLE. You can find the guide here: https://github.com/kevmo314/codec-from-scratch

  2 40 8.2 D

  Image encoding and decoding library for D. Detailed layout control. Experimental codec QOIX.

  

Also extended QOI to make QOIX, a triple codec that can also encode 10-bit and 1 and 2-channels images. So you could say it's 3x the complexity.
