<div>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,
