// .NAME vtkImageCast - Image Data type Casting Filter
|
|
// .SECTION Description
|
|
// vtkImageCast filter casts the input type to match the output type in
|
|
// the image processing pipeline. The filter does nothing if the input
|
|
// already has the correct type. To specify the "CastTo" type,
|
|
// use "SetOutputScalarType" method.
