PGM Raw at a glance

PGM Raw

The raw PGM branch reflects the practical evolution of Netpbm-style tool formats: keep the tiny header and easy parsing, but move the pixel raster into a binary form that is much more usable for real data sizes.

XPM at a glance

XPM

Before today's relatively small set of mainstream consumer image formats dominated everyday use, desktop software, workstations, GUI systems, and early graphics tools produced many specialized raster formats with local importance.
