ppmntsc

Make the RGB colors in a PPM image compatible with NTSC or PAL color systems. More information: https://netpbm.sourceforge.net/doc/ppmntsc.html.

  • 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}}
