- 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.
- UBRL6 (Unicode Braille 6 dots) is a text encoding format that uses a 6 dot braille cell to represent characters, symbols, and punctuation marks. It is used to convert text into a tactile code system that can be read by visually impaired individuals.
