[vtkusers] current extent of renderer

[mirko heuegger]

Hello!

Is it possible to determine the extent, in word-coordinates or pixels,
(_after_ zooming in) in a vtkRenderer?

I found some functions like vtkRenderer.ComputeVisiblePropBounds(),
but this functions returns the full extent and not the current visible one.


Thanks in Advance.
