[vtkusers] vtkInteractorStyleRubberBandZoom::OnMouseMove() is slow on maximised windows

Hi All,

 

My experience is that the response to mouse move events using
vtkInteractorStyleRubberBandZoom degrades significantly as the window
size increases. At full screen, SetPixelData() takes about 0.5s for each
mouse move event.

 

Previously, I was using a custom widget to display a rectangular
selection by simply resizing a 2D actor. The response to a mouse move
was immediate.

 

I would prefer to use vtkInteractorStyleRubberBandZoom. Does anybody
have any suggestions for speed improvements?

 

Thanks.

 

John Platt
