[vtkusers] Blended image display

[Matthieu Ferrant]

Hi,

I would like to know if it is possible to blend and visualize two images
within a single vtkImager. I have tried to create two 2D actors for both
images, setting their respective opacities to 0.5, but I can only see
the last image I add to the vtkImager. I also tried playing with
SetDisplayLocationToBackground but that wouldn't change anything. I did
experiment with the vtkImageBlend filter, but I'd like something more
interactive (i.e. be able to slide from one image to another with
varying opacity).

What would be the best way to do this ?

thanks,

matt
