/**

* @class vtkImageClip
|
|
* @brief Reduces the image extent of the input.
|
|
*
|
|
* vtkImageClip will make an image smaller. The output must have
|
|
* an image extent which is the subset of the input. The filter has two
|
|
* modes of operation:
|
|
* 1: By default, the data is not copied in this filter.
|
|
* Only the whole extent is modified.
|
|
* 2: If ClipDataOn is set, then you will get no more that the clipped
|
|
* extent.
