Hi all,
I have a little problem with vtk. I explain : I display an image with a vtkRenderer object in a vtkImageViewer2 object. And with a windowInteractor object, when the user right click on the image, he can drag the mouse to make a zoom. How can I get the zoom factor?
And a second question : when the image is displayed, a reduction factor is applyed to fit into the viewport. How can I get the reduction factor?

Thx a lot for your answers,
Bye.
