Description
RB is an eBook file format that was developed by NuvoMedia. It was first used in Nuvo Media’s Rocket eBook device. It contains the contents of the book in HTML form.
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.
