Leadtools.ImageProcessing.Core Namespace > RakeRemoveCommandEventArgs Class : RakeRemoveCommandEventArgs Constructor



region
LEADTOOLS Leadtools.RasterRegion representing the rake to be removed. It is the programmer's responsibility to dispose this region when it is no longer needed.
length
Length (in pixels) of the rake base line.
Initializes a new RakeRemoveCommand with explicit parameters.

Syntax

Visual Basic (Declaration) 
Public Function New( _
   ByVal region As RasterRegion, _
   ByVal length As Integer _
)
Visual Basic (Usage)Copy Code
Dim region As RasterRegion
Dim length As Integer
 
Dim instance As New RakeRemoveCommandEventArgs(region, length)
C# 
public RakeRemoveCommandEventArgs( 
   RasterRegion region,
   int length
)
C++/CLI 
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 this region when it is no longer needed.
length
Length (in pixels) of the rake base line.

Example

Runs the RakeRemoveCommand on an image.
