Detailed Description

Data class for Transfer Function info, either 2D or 3D.

Used as base for ImageTF3D and ImageLUT2D.

Alpha transfer function: Set either LLR/alpha or OpacityMap, this updates the data as shown.

    set            set
     |              |
  LLR/alpha --> OpacityMap --> alphaTF

Color transfer function: Set either ColorMap or LUT, plus the Win/Level, this updates the data as shown.

    set        set
     |          |
  ColorMap --> LUT -------> colorTF
                        |
             Win/Level--|
                |
               set
