   RasterRegion^ region, 
   int length 
) 
__init__(self,region,length) # Overloaded constructor 

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.
