// .NAME vtkThreadedImageAlgorithm - Generic filter that has one input..
// .SECTION Description
// vtkThreadedImageAlgorithm is a filter superclass that hides much of the
// pipeline complexity. It handles breaking the pipeline execution
// into smaller extents so that the vtkImageData limits are observed. It
// also provides support for multithreading. If you don't need any of this
// functionality, consider using vtkSimpleImageToImageAlgorithm instead.
// .SECTION See also
// vtkSimpleImageToImageAlgorithm
