    A Brooktrout file consists of a CCITT Group 3 (G3) compressed file with a 128-byte header designed by Brooktrout Technology. The header fields include a constant that identifies the file as Brooktrout, a version number, the horizontal and vertical resolutions of the image in dots/mm, the number of bits per pixel, and the number of pixels per line.
