rasttopnm – convert a Sun rasterfile into a portable anymap
Reads a Sun rasterfile as input. Produces a portable anymap as output.
The type of the output file depends on the input file – if it’s black &
white, a pbm file is written, else if it’s grayscale a pgm file, else a
ppm file. The program tells you which type it is writing.
