vtkImageQuantizeRGBToIndex takes a 3 component RGB image as input and produces a one component index image as output, along with a lookup table that contains the color definitions for the index values. This filter works on the entire input extent - it does not perform streaming, and it does not supported threaded execution (because it has to process the entire image).
To use this filter, you typically set the number of colors (between 2 and 65536), execute it, and then retrieve the lookup table. The colors can then be using the lookup table and the image index.

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
