[vtkusers] vtkImageActor

[Mike Gagnon]

ok thanks I'll do that for its orientation.  But as for the image 
boundaries and resizing the image, is the matrix also the best bet? I am 
hoping to align the image perfectly with the bottom left of the renderer 
and was thinking I could use vtkImageActor::SetDisplayExtent (not 
getting the right results with that).
