[vtkusers] Disabling interpolation when zooming

[Shady Shidfar]

Hi everyone, does anyone know how I can disable interpolation when zooming. I'm displaying an image and while I zoom (move the camera) the image becomes smooth and the pixels can't be distinguished explicitly. I need to find a way to disable the feature so I'll be able to view the pixel borders precisely.
 
Thanks for any help
Shaadi
