[vtkusers] Saving BMP without visualizing them

[Dmitri Danewitz]

Hello Jim,
 
thanks a lot! Somehow it worked even easier: I just set the "OffScreenRenderingOn()"

Hi Dmitri,

I haven't seen a reply to your message, and I haven't used VTK for a 
while but I think what you want to do is to use the off screen 
renderer. Something like VTKOffScreenRenderer. It may have the OS in 
the name, I don't remember.

Good luck,
Jim
