// .NAME vtkImageShiftScale - shift and scale an input image
|
||
|
|
// .SECTION Description
|
||
|
|
// With vtkImageShiftScale Pixels are shifted and then scaled. As
|
||
|
|
// a convenience, this class allows you to set the output scalar type
|
||
|
|
// similar to vtkImageCast. This is because shift scale operations
|
||
|
|
// frequently convert data types.
