[vtkusers] Superclass not being set correctly?

[Jérôme]

Hi David,
In your vtkImageCamera.h, the line

   vtkTypeRevisionMacro(vtkImageCamera,vtkObject);

effectively tells that vtkImageCamera "is a" vtkObject!

You should use
   vtkTypeRevisionMacro(vtkImageCamera,vtkPhysicalCamera)
instead

HTH,
Jerome
