[vtkusers] SetInputConnection for vtkPNGReader

[John Eke]

Thanks a lot, I suspected so. My problem however is that I need to read 
the image using vtkPNGReader, but I need to get this data in a format 
where I can get its output, perform some more processing, then set the 
updated input instead of writing to a file and have it read all over again.

Any suggestions?
