- Description
- A PPSX file is a slide show created by Microsoft PowerPoint or another presentation program, such as OpenOffice Impress or SoftOffice Presentations. It contains a finished collection of slides that are used for slide show playback.
- 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.
