- Description
- This is a bitmap graphics file format created for printers and terminals by Digital Equipment Corporation (DEC). It is another extension of the SIXEL file.
- 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.
