[vtk-developers] vtkImageReader2

[David Doria]

It looks like vtkImageReader2 is a superclass for many of the image
reader classes. However, it seems that you can instantiate it and use
it without errors, but it just doesn't do anything:

Is there a way to make one of the functions pure virtual so that it is
obvious and impossible to instantiate directly? I think that would
eliminate some confusion.
