- Description
- An RGBA file is a color bitmap image format created by Silicon Graphics (SGI). It is similar to the .RGB file as it supports color RGB channels with an alpha 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.
