ScrollBy Method

public virtual void ScrollBy( 
   LeadPoint point
)

'Declaration
 

Public Overridable Sub ScrollBy( _
   ByVal point As LeadPoint _
) 

Parameters

point

The amount by which to scroll the viewer.

This method will add point to the current ScrollOffset. Therefore, this method will follow the same rules governing the minimum and maximum values of ScrollOffset.

If the value of ScrollMode is ControlScrollMode.Hidden and RestrictScroll is set to false, calling ScrollBy will work with any value since there's no restriction on the scroll offset. The helper methods ScrollByRestrict and RestrictScrollOffset can be used to perform scrolling by a certain amount while virtually restricting the offset.

ImageViewerPanZoomInteractiveMode uses this method to perform its operation.
