Portable Pixmap

PPM, which stands for Portable Pixmap, is a straightforward image storage format. It supports three types of images: color (PPM), grayscale (PGM), and black and white (PBM). These formats are particularly useful as an intermediary representation during the conversion of raster image files between different platforms. The development of the PPM format is credited to Jeff Poskanzer.
