[vtkusers] Clipping vtkImageData

[Robert Mitchell]

Hi All,

I am trying to simply clip an image with the usual click and
drag/release operation with the mouse. Should I be using vtkPointPicker
, vtkWorldPointPicker or other, and then use that pick information to
get the two corner point Id's and use vtkImageClip with those extents?
Or is there a much better way?

Thanks in advance,
Rob
