ppmtorgb3 [input.ppm]
Read from stdin
cat [input.ppm] | ppmtorgb3
说明
ppmtorgb3 reads a PPM (Portable Pixmap) image and writes three PGM (Portable Graymap) images as output: one each for the red, green, and blue channels. Output filenames are derived from the input filename by stripping any extension and appending .red, .grn, and .blu. For example, separating lenna.ppm produces lenna.red, lenna.grn, and lenna.blu. When input comes from stdin, the names default to noname.red, noname.grn, and noname.blu. There are no options specific to ppmtorgb3, but it accepts the common options shared by all programs based on libnetpbm.
