- 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.
- An EMZ file contains an Enhanced Metafile (.EMF file) that has been compressed with the .GZIP compression algorithm. It is compressed to reduce storage space and be more easily transferred between applications. EMZ files are typically used by Microsoft programs such as Visio and the Office suite, which includes Word and PowerPoint.
