BorderRemoveCommandEventArgs Constructor

Summary

Initializes a new BorderRemoveCommand class object with explicit parameters.

Syntax

C++/CLI

Java

Python

public BorderRemoveCommandEventArgs( 
   RasterImage image, 
   RasterRegion region, 
   BorderRemoveBorderFlags border, 
   LeadRect boundingRectangle 
)

public BorderRemoveCommandEvent( 
   Object source,  
   RasterImage image,  
   RasterRegion region,  
   int border,  
   LeadRect boundingRectangle 
)

public: 
BorderRemoveCommandEventArgs(  
   RasterImage^ image, 
   RasterRegion^ region, 
   BorderRemoveBorderFlags border, 
   LeadRect boundingRectangle 
)

__init__(self,image,region,border,boundingRectangle) # Overloaded constructor

Parameters

image
RasterImage object that references the affected image

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

border
Flag that indicates which border is being processed.

boundingRectangle
Rectangle object that contains the bounding rectangle of the border being processed.
