// .NAME vtkImageWrapPad - Makes an image larger by wrapping existing data.
// .SECTION Description
// vtkImageWrapPad performs a modulo operation on the output pixel index
// to determine the source input index.  The new image extent of the
// output has to be specified.  Input has to be the same scalar type as 
// output.
