Detailed Description

Handling of color and opacity for 2D slices.

Set the basic lut using either setLut() or setColorMap(), then modify it with window and level. The alpha channel in this lut is ignored. The opacity is controlled with LLR and Alpha values, which creates a step function for the opacity. The AlphaMap from the superclass is not used, it is overwritten by setting llr/alpha.

The slicer classes will use the data either by getting the LUT+parameters(win/lvl(llr/alpha) and, or by getting OutputLookupTable() which is a merge of the LUT and parameters.

void cx::ImageLUT2D::internalsHaveChanged ( )

protectedvirtual

Rebuild the opacity tf from LLR and alpha. This is because the 2D renderer only handles llr+alpha.
