// .NAME vtkImageToImageFilter - Generic filter that has one input..
|
|
// .SECTION Description
|
|
// vtkImageToImageFilter 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 vtkSimpleImageToImageFilter instead.
|
|
