Description
The base image, which must be included, is intended to be the original PPM file
without modifications. If there are one or more PPM images in the standard
input, each image will be compared pixel by pixel with the base image. If two
pixels are equal a white (FALSE) value will be placed in the corresponding
pixel of the PBM
image. If they are different, a black (TRUE) value will be placed there.
All input files must have the same size as the base image.
