pixuntile — break image up into separate files
pixuntile performs the inverse operation of pixtile(1). It takes a large image composed of a collection of small images and places each of them in a separate file. The input and output files are assumed to be in pix(5) format. By default, the input file is assumed to be 512x512 pixels in size.
The output files have a default width of 64 pixels
and are usually square, i.e. have the same height as width.
