-

  Simple Mode Options: **-i** in\_intent    p = perceptual, r = relative colorimetric,

-

  s = saturation, a = absolute colorimetric

- **-o** out\_intent

  p = perceptual, r = relative colorimetric, s = saturation, a = absolute colorimetric

- Gamut Mapping

  Mode Options:

- **-i** intent

  set linking intent from the following choice:
