// .NAME vtkImageMagnify - magnify an image by an integer value
|
|
// .SECTION Description
|
|
// vtkImageMagnify maps each pixel of the input onto a nxmx... region
|
|
// of the output. Location (0,0,...) remains in the same place. The
|
|
// magnification occurs via pixel replication, or if Interpolate is on,
|
|
// by bilinear interpolation.
