 Usage

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.
To create an instance of class vtkImageQuantizeRGBToIndex,
simply invoke its constructor as follows

    obj = vtkImageQuantizeRGBToIndex



 Methods

The class vtkImageQuantizeRGBToIndex has several methods
that can be used. They are listed below. Note that the
documentation is translated automatically from the VTK
sources, and may not be completely intelligible. When in
doubt, consult the VTK website. In the methods listed below,
obj is an instance of the vtkImageQuantizeRGBToIndex class.

* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkImageQuantizeRGBToIndex = obj.NewInstance ()
* vtkImageQuantizeRGBToIndex = obj.SafeDownCast (vtkObject
  o)
* obj.SetNumberOfColors (int ) - Set / Get the number of
  color index values to produce - must be a number between 2
  and 65536.
* int = obj.GetNumberOfColorsMinValue () - Set / Get the
  number of color index values to produce - must be a number
  between 2 and 65536.
* int = obj.GetNumberOfColorsMaxValue () - Set / Get the
  number of color index values to produce - must be a number
  between 2 and 65536.
* int = obj.GetNumberOfColors () - Set / Get the number of
  color index values to produce - must be a number between 2
  and 65536.
* vtkLookupTable = obj.GetLookupTable () - Get the resulting
  lookup table that contains the color definitions
  corresponding to the index values in the output image.
* double = obj.GetInitializeExecuteTime ()
* double = obj.GetBuildTreeExecuteTime ()
* double = obj.GetLookupIndexExecuteTime ()
