- Description
- Image saved in the native graphics format used by Silicon Graphics workstations; can store 8 to 32 bits per pixel; also supports Run-length encoding (RLE) compression for reducing the image file size.
- 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.
