Both formats, briefly
JP2IN
JP2 is the JPEG 2000 container, and it works on wavelets rather than the small blocks of ordinary JPEG. It compresses either lossily or losslessly, blurs rather than blocks as quality drops, and can be decoded progressively or only for the region you asked for. Those properties made it standard in digital cinema packages, medical imaging systems, and satellite and mapping data. Browsers largely skipped it, so files usually need converting for general use.
PPMOUT
PPM is deliberately plain: a short text header followed by raw RGB values, with no compression and no structure to parse. That is what you want when you are writing image code yourself or piping frames between command line tools, because reading and writing it takes a few lines. It belongs to the Netpbm family, next to PGM for grayscale and PBM for pure black and white. The files are enormous, so convert before sending one anywhere.
