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.
