[vtkusers] Image size

[Eric E. Monson]

Hey Huseyin,

If calling renderer->ResetCamera(imageActor->GetBounds()) doesn't get you close enough, you can also look at the example on the Wiki where an image is used as the background for a window:

http://www.cmake.org/Wiki/VTK/Examples/Images/BackgroundImage

I think this example came out of this mailing list thread:

http://markmail.org/message/taknydvbtdhv6bsx

I seem to recall anther recent thread talking about an image filling a window, but I can't find it right now.

Good luck,
-Eric
