DDS w skrocie
DDS
DDS grew out of Microsoft's graphics API and game-development ecosystem, which is why it feels more like an engine or texture-delivery format than a conventional consumer image file.
PNM w skrocie
PNM
PBM, PGM, PPM, PNM, and later PAM come from the tool-centric tradition of keeping image interchange formats easy to parse, script, and transform.
