[vtkusers] Set position of vtkImageSlice

[Jonathan Ruiz Peinado]

You can perform translations, origin relocation, etc with
vtkImageChangeInformation, I think it could work for you.

vtkImageChangeInformation normalized = new vtkImageChangeInformation();
normalized.SetInputConnection( reader.GetOutputPort() );   // You can use
setInput instead
normalized.SetOutputOrigin( 100, 100, 0 );     //There're others methods
that can fit better your needs take a look to the documentation.
                .SetOrigin
                .Set...Translation
normalized.Update();
