[vtkusers] World to Dataset coordinates

Hi there, 

I am using a vtkPropPicker to pick a point on an imageActor. I use the Pick(
) and GetPickPosition( ) functions to get the world coordinates of the
picked point. How on earth do I convert it to Dataset coordinates, i.e. the
actual image coordinates? Am I using the wrong picker class? I noticed that
PropPicker does not return point/cell ids. 

Any help will be appreciated,
