[vtkusers] HELP ME! HELP ME! HELP ME! HELP ME! HELP ME! Two questions (To see image attached)

What is the object you are rendering?
Is it a vtkImage or vtkPolydata? If you can send  the  rendering code I 
can have an other suggestion. If it is a vtkImage you can easily obtain 
the width and height. As long as the renderwindow is not  in same scale 
with your object you will always have margins or some parts of the 
object will not be visible.
