  • Make the RGB colors in a PPM image compatible with NTSC color systems:
    ppmntsc path/to/input_file.ppm > path/to/output_file.ppm
  • Make the RGB colors in a PPM image compatible with PAL color systems:
    ppmntsc --pal path/to/input_file.ppm > path/to/output_file.ppm
  • Print the number of illegal pixels in the input image to `stderr`:
    ppmntsc --verbose path/to/input_file.ppm > path/to/output_file.ppm
  • Output only legal/illegal/corrected pixels, set other pixels to black:
    ppmntsc --legalonly|illegalonly|correctedonly path/to/input_file.ppm > path/to/output_file.ppm
