[vtkusers] raw image 3D rendering

[John Vard]

Hello Users

I'm having difficulty displaying a .raw image within the 3D render window. I'm 
currently using the vtkImageCast Class to alter the scalar type to unsigned 
character which is required by vtkImageActor. However the resulting render is 
not as expected. It appears that the change in scalar type is altering the 
pixel colouring, perhaps... How can I correct this and 3D render the image 
correctly?? Thanks for your time
