- 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.
- Compressed raster image format developed by Microsoft; similar to the .JPG format, but uses a higher degree of compression and supports both lossy and lossless compression; used primarily for high-resolution digital photographs; can be used with several Microsoft products including Windows Photo Viewer, Windows Live Movie Maker (WLMM), and Microsoft Word.
