[vtkusers] xxxxxSPAMxxxxx vtkInteractorStyleJoystickActor doesn't pick vtkImageActor

[Pham Sy Quy]

Hi all,

I used vtkInteractorStyleJoystickActor as interaction style, my renderer 
includes one vtkImageActor and one vtkActor (a cone made from vtkConeSource)
I couldn't pick image, it still work fine with the cone. I dont want to 
use vtkInteractorStyleImage because it doesnt allow to rotate images.
Did i miss something?

Please help, thanks.

Quy,
