# Usage

vtkExtractSelectedThresholds extracts all cells and points with attribute values that lie within a vtkSelection's THRESHOLD contents. The selecion can specify to threshold a particular array within either the point or cell attribute data of the input. This is similar to vtkThreshold but allows mutliple thresholds ranges. This filter adds a scalar array called vtkOriginalCellIds that says what input cell produced each output cell. This is an example of a Pedigree ID which helps to trace back results.

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

      obj = vtkExtractSelectedThresholds
