[vtkusers] including alpha channel in VTK image actor

[Cam Crews]

Hi, 
  I'm unable to get an alpha value to properly work within my VTK
image actor; any experience with this?



  I have a 4 component image image dataset that I want to be able to
use for image display in both 2D and 3D - I need to have an alpha
channel for the 3D display...
