Class ColorTransfer

Object
  common:Generic
      common:ColorTransfer

Direct Known Subclasses:

DMJ_Colorize, NullColorTransfer

class 
Generic:ColorTransfer

This is a generic color transfer class. It accepts one or more color values in sequence and returns a color value for each. Compare this to the Transform and Transfer base classes.
