PPSX at a glance

PPSX

PPSX followed the same modernization path as PPTX: keep the user workflow concept, but place it in the package-based Open XML world.

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.
