what im trying to do is a way to get image produced by vtkImageViewer and process on it.

i have done this so far but it seems not working:  
vtkImageData data = \_viewer.GetInput();  
Bitmap bitmap = data.ToBitmap();

i get this exception when i run the code : Invalid Number of Scalar Components

what do miss? what should i do??
