- 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.
- Encapsulated PostScript Interchange TIFF Preview (EPT) is a file format for storing raster graphics. It is a combination of a TIFF (Tagged Image File Format) preview image and an EPS (Encapsulated PostScript) vector image, and is typically used for exchanging vector graphics between applications.
