When ICC profiles are used to convert color spaces, this
parameter determines how colors outside the gamut of the
destination color space are remapped.
- Perceptual - the whole gamut of the original image is
compressed until it fits within the gamut of the destination color
- Relative Colorimetric - leaves all colors the same when they
fall within the destination gamut but those that fall outside the
destination gamut are mapped to the nearest 'in gamut'
- Saturation - preserves the relative saturation of the 'out of
gamut' colors as they are mapped from one color gamut to the other
even at the expense of having accurate hue and lightness.
- Absolute Colorimetric - all colors within the original color
gamut are mapped exactly to the same colors within the destination
