Better Portable Graphics (BPG) image format created to replace the JPEG format; provides the same quality as JPEG images but in a smaller file size; supports lossless compression; natively supports 8 to 14 bits per channel.
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.
