// .NAME vtkImagePadFilter - Super class for filters that fill in extra pixels.
|
|
// .SECTION Description
|
|
// vtkImagePadFilter Changes the image extent of an image. If the image
|
|
// extent is larger than the input image extent, the extra pixels are
|
|
// filled by an algorithm determined by the subclass.
|
|
// The image extent of the output has to be specified.
