[vtkusers] visuallize large image

[Moti Freiman]

Hello,
I want to visuallize a large image (2000*3000 pixels) in window with 
normal size (600*800) using vtkImageViewer.
one way to do it is to use vtkImageResample filter before set the input 
to the imageviewer. however i don't want to use resampling. instead of 
it yi want to zoom a camera or something like this.
do someone have a code example that to something like this?
Thanks,
Moti
