Can you pre-process your images and add an alpha channel with 0 where you want transparency? You should be able to find or make a test image pretty fast to see if it works.

Dave P,

That did the trick. I used the itkRGBAPixel type for my image then
wrote it as a TIFF and the transparency is as expected in ParaView.
