David, is there a worked example of this? We tried to figure this out yesterday but \
ended up with black rectangles on the screen.  I.e. What color order does \
vtkImageImport support? Is it RGBA or ARGB or ffRGB or what? How do I set the data \
type to unsigned int which is what comes out of the QImage we are trying to use as a \
source? 

Then when trying to render the image the vtkImageActor complains it only supports \
unsigned char but the vtkImageScaleShift does nothing... An example would really help \
I guess...
