[vtkusers] how to clear the screen in renderer window?

[varshini varshini]

Hai all,

I am opening and displaying an image in a renderer window in a dialog 
box.When I try to open and load another image the previous image appears on 
the screen and is not cleared. I tried using

renWin->Clean();
and
ren->Clear();

to clear the previous image , but still I wasn't able to solve it. Am I 
missing something or is there a different option to get this done.Any help 
will be greatly appretiated.

Thanks in advance

Varshini
