[vtkusers] ImageViewer2 extent problem

[Mark Wyszomierski]

I had this problem too, vtkImageViewer2 is just a wrapper around a few 
classes that put it all together, the one you need to alter is the 
underlying image actor object. So get it, call SetDisplayExtent() with the 
new image dimensions on the image actor, and reset your camera. This worked 
for me. Goodluck,
 Mark
