Modifying the BitmapView Class to Catch the New Actions
First, the interface of the view must be modified to declare the new actions:
IlvDvBeginInterface(BitmapView)
Method1(BitmapHasChanged, bitmapHasChanged, IlAny, region)
Action(ZoomIn, zoomIn)
Action(ZoomOut, zoomOut)
IlvDvEndInterface1(IlvDvFormView)
Then, the BitmapView::zoomIn and BitmapView::zoomOut methods need to be implemented.
