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.
PCXOUT
PCX is a DOS era format, originally the native file of PC Paintbrush, and for years it was how images moved between early PC programs. It uses run length encoding, supports palettes up to 24 bit color, and is simple enough that a decoder fits in a page of code. Nothing new is written in PCX today. You run into it in old archives, scanner utilities and retro computing projects.
