- 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.
- CIP is a proprietary image format developed by Cisco Systems for its IP phones. It is used to store images, backgrounds, icons, and logos, and is optimized for use on Cisco IP phones. It is not compatible with other image formats.
