'Usage
 
Dim region As RasterRegion
Dim length As Integer
 
Dim instance As New RakeRemoveCommandEventArgs(region, length)

public RakeRemoveCommandEventArgs( 
   RasterRegion region,
   int length
)

function RakeRemoveCommandEventArgs( 
   region ,
   length 
)

public:
RakeRemoveCommandEventArgs( 
   RasterRegion^ region,
   int length
)

Parameters

region: LEADTOOLS Leadtools.RasterRegion representing the rake to be removed. It is the programmer's responsibility to dispose of this region when it is no longer needed.
