- Description
- The PLT file extension is a vector-based plotter file developed by Autodesk, Inc. to contain plotting details from a certain CAD or computer-aided design file.
- 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.
