What is a .ppm file?
PPM (Portable Pixmap) is a deliberately simple truecolor image format from the Netpbm family, storing RGB pixels as either ASCII text or raw binary after a small text header. It uses no compression, making files large but trivial to parse. It is common in academic, scientific, and toolchain contexts.
How to use this file
Use an example PPM to test minimal image parsers, verify raw RGB pipeline output, or serve as an easily hand-inspectable intermediate in conversion tools.
