[vtkusers] How to blend RGB and gray image?

[kidane]

Ya, I took the RGB as first input and then the grayscale as shown below:

		vtkSmartPointer<vtkImageBlend> imgBlender =
vtkSmartPointer<vtkImageBlend>::New();		
		imgBlender->SetOpacity( 0, 0.5 );
		imgBlender->SetOpacity( 1, 0.5 );
		imgBlender->AddInput(colormapImage);
		imgBlender->AddInput(grayscaleImage);

thanks for your help
