)

'Usage
 
Dim instance As RasterImageViewer
Dim e As RasterViewerRectangleEventArgs
 
instance.OnInteractiveRegionEllipse(e)

protected virtual void OnInteractiveRegionEllipse( 
   RasterViewerRectangleEventArgs e
)

 function Leadtools.WinForms.RasterImageViewer.OnInteractiveRegionEllipse( 
   e 
)

protected:
virtual void OnInteractiveRegionEllipse( 
   RasterViewerRectangleEventArgs^ e
)

Parameters

e: A RasterViewerRectangleEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate. The OnInteractiveRegionEllipse 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 OnInteractiveRegionEllipse in a derived class, be sure to call the base class's OnInteractiveRegionEllipse method so that registered delegates receive the event.

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
