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.
Image file format related to the .PNG format, but uses lossy compression like standard .JPG files; developed as a sub-format for .MNG objects, but can also be used as a standalone raster image format.
