Hi,
I am newbie at vtk and in my application, I need to display an MRI image and
interact with the mouse on it to draw on it. So far I can display the Image,
I can pick it with the mouse but I don't know how to get the 2D coordinates
of the picked position in the image domain. I can only get the position
using " GetLastEventPosition" but inside the render window and not the image
itself. Could anyone help on this matter ?
thanks
