Detailed Description

map scalar values into colors or colors to scalars; generate color table

vtkWindowLevelLookupTable is an object that is used by mapper objects to map scalar values into rgba (red-green-blue-alpha transparency) color specification, or rgba into scalar values. The color table can be created by direct insertion of color values, or by specifying a window and level. Window / Level is used in medical imaging to specify a linear greyscale ramp. The Level is the center of the ramp. The Window is the width of the ramp.

Warning

vtkWindowLevelLookupTable is a reference counted object. Therefore, you should always use operator "new" to construct new objects. This procedure will avoid memory problems (see text).
