Detailed Description

Handler for the transfer functions used in 3d image volumes.

Used by Image.

Set the basic lut using either setLut() or setColorPoint(), then modify it with window and level. Set the alpha channel using setAlphaPoint(), or override it by creating a opacity step function with LLR and Alpha.

The volume rendering classes can use the data by getting OpacityTF and ColorTF.
