[Vv] Window Level Fusion Slider

[Rajamani, Kumar (GE Global Research)]

Dear Simon, Joel

While using the fusion feature, I realized that the slider 
Changes the opacity of the background image (The combined image
Opacity is changed)

I would like to have a functionality where the opacity slider
Changes the opacity of the overlay only 
The background image should not be altered and should be always visible
The extent of overlay should only be altered by the fusion slider
Is this change possible ? Where could this change be  done ?

I have tried vtkBlendImages but without success

Warm Regards
Kumar



Dear Kumar,
Wrt to the w/l of the fusion image, I totally agree and that's why the
guy that developed this functionality has added specific text boxes for
the w/l of the fusion image. If you open an image and add a fusion
image, go to the overlay tab and you can set the w/l of the overlay
image. Therefore, the w/l of the image and it's overlay are totally
independent.
Let me know if you feel that it's not enough, Simon
