Detailed Description

template<class VTIn, class LUT>
struct vigra_ext::LUTFunctor< VTIn, LUT >

functor to apply a LUT to gray and color images.

This is a safe, and iterpolatating table lookup.

if the argument has a higher bit count than lut.size(), interpolation will take place.

This is slower, because there is a size check at runtime, which might be placed in a template parameter.

floating point values between 0..1 are mapped to min and max of the lookup table.
