protected virtual void OnInteractiveRegionFreehand( 
   RasterViewerPointsEventArgs e
)
'Declaration
 
Protected Overridable Sub OnInteractiveRegionFreehand( _
   ByVal e As RasterViewerPointsEventArgs _
) 
'Usage
 
Dim instance As RasterImageViewer
Dim e As RasterViewerPointsEventArgs
 
instance.OnInteractiveRegionFreehand(e)
protected virtual void OnInteractiveRegionFreehand( 
   RasterViewerPointsEventArgs e
)
 function Leadtools.WinForms.RasterImageViewer.OnInteractiveRegionFreehand( 
   e 
)
protected:
virtual void OnInteractiveRegionFreehand( 
   RasterViewerPointsEventArgs^ e
) 

Parameters

e
A RasterViewerPointsEventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate. The OnInteractiveRegionFreehand method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class. Notes to Inheritors: When overriding OnInteractiveRegionFreehand in a derived class, be sure to call the base class's OnInteractiveRegionFreehand method so that registered delegates receive the event.
Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
