Just to add to this list, even MacPaint used RLE on a per-scan line basis. I recently wrote about decoding MacPaint files[0]. So, replying to the gp post, yes it is in a sense reinventing the wheel. But sometimes the wheel needs to get reinvented because you have a new vehicle that could use a different type. And I would say the original poster felt he needed part of the modern wheel without the tire, so he had to go back to earlier wheel designs in a modern context. Okay, I've stretched the analogy too far! [0] http://www.observationalhazard.com/2021/09/building-retro-dither-dithering.html http://www.observationalhazard.com/2021/09/building-retro-di...
