RakeRemoveCommandEventArgs Constructor (RakeRemoveCommandEventArgs)








Leadtools.ImageProcessing.Core Namespace > RakeRemoveCommandEventArgs Class : RakeRemoveCommandEventArgs Constructor
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.
Length (in pixels) of the rake base line.
Initializes a new RakeRemoveCommand with explicit parameters.
Syntax
public RakeRemoveCommandEventArgs( 
   RasterRegion region,
   int length
)
'Declaration
 

Public Function New( _
   ByVal region As RasterRegion, _
   ByVal length As Integer _
)
'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 RasterRegion representing the rake to be removed. It is the programmer's responsibility to dispose of this region when it is no longer needed.
length
Length (in pixels) of the rake base line.
Example

Runs the RakeRemoveCommand on an image.
