PGM in sintesi
PGM
PBM, PGM, PPM, PNM, and later PAM come from the tool-centric tradition of keeping image interchange formats easy to parse, script, and transform.
MetaPost in sintesi
MetaPost
John Hobby developed MetaPost from MetaFont ideas, and the system later evolved into the MPlib era so TeX and LuaTeX workflows could keep high-quality vector graphics close to typeset documents.
