Sixel is a primitive and wasteful format. Most sixel terminals also support the iTerm2 format--fewer bytes, full color instead of paletted, and no pixel re-processing required. Much better!

This question may be offtopic, but... Is there any way to decode images from Sixel to fb graphics? Maybe convert Sixel to PPM to then open with fbsplash? Thanks!
