- 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.
- VIPS is a libvips file format mainly used for calculations, but it can also store images. The main advantage is that it has no size limit; it's fast and straightforward. Nonetheless, most applications can't view it, so converting it to a more popular format is the only way to work around it.
