Ideadfish

Ideadfish is an image version of Deadfish, with char output and operates on a 8 bit accumulator, created by User:None1, overflow and underflow wraps around.

Commands

All ideadfish programs are RGB (or RGBA, but the alpha channel will be ignored in that case), images, its height must be 1, every pixel is a command (pixels that are not in the tables are NOPs.
