[vtkusers] Rendering raw X-ray problem

[John Vard]

I'm having difficulty displaying X-rays in raw file format. To display the 
image in the render window vtkImageActor demands that the scalar type of the 
image be set to Unsigned Character. Yet this appears to alter the display 
colouring. Firstly can anybody explain why the image is being altered and how 
can I overcome this?? Really would appreciate some help on this. It's doing 
my head.. Ta
