Interface GammaMapping

All Known Implementing Classes:
ModifiedGammaMapping, SimpleGammaMapping
public interface GammaMapping
Interface to be implemented by gamma correction classes. All in/out component values are assumed to be in [0,1]. Implementing classes must at least define a double version of the required methods but are free to override the associated float versions.
