Description
File extension ptif is mainly associated with the Pyramid encoded TIFF bitmap graphics file format. Multi-resolution TIFF containing successively smaller versions of the image down to the size of an icon.
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.
