Make PGM Files

PGM (short for Portable Gray Map) is an image format originally created to facilitate graphic data transfers among various platforms. Not only do PGM files feature a binary representation, but they are usually stored in ASCII text format.

PGM images also contain header information and a grid of numbers that illustrate shades of gray varying from black (0) to white (up to 65,536).

To be able to make their own PGM image files, users will be have to choose and use a dedicated application with support for this particular graphics format.
