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.
JPS at a glance
JPS
JPS belongs to the period when consumer 3D displays, cameras, and media players experimented with stereo-photo conventions built on ordinary JPEG assets instead of inventing entirely new everyday imaging stacks.

FAQs
Why convert PGM Raw to JPS?
Convert to JPS when preserving stereoscopic photo pairs, preparing side-by-side 3D images for compatible viewers, or maintaining archives from cameras and displays that used the JPEG Stereo convention.
It is mainly useful for legacy stereoscopic-image exchange rather than mainstream still-image publishing.
What changes when converting PGM Raw to JPS?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to JPS adds layer support. Moving to JPS adds vector scaling. Moving to JPS adds streaming delivery.
What should I review after converting PGM Raw to JPS?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
