Description
A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
Created by JBIG (Joint Bi-level Image Experts Group), JBG is a lossless file format that contains both colored and monochrome images. Commonly used to compress fax images, and it has better compression than G3 and G4 compression codecs.
