[vtkusers] limits in rendering size?

[WolfgangZillig]

Hi,

I'm facing the problem that I read in a 1024x1024 matrix but I don't get 
it displayed completely: the upper/lower part is missing. When I flip 
the image it is the opposite way around. Is there a limit in rendering 
dimension when my display only has 800 pix height?
I'm preparing some example data at the time, but the binary data that 
I'm reading in is about 2MB.



Thanks for any information.

Wolfgang

PS I'm running vtk in Python 2.5
