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.
Ptiff is a type of image file that is created by compressing a TIFF (Tagged Image File Format) image using a wavelet-based encoding, known as pyramidal encoding. This type of file can store both lossy and lossless compressed images and is often used for storing large-scale images such as aerial photographs or medical images.
