LineRemoveCommandEventArgs Constructor

Summary

Initializes a new LineRemoveCommand with explicit parameters.

Syntax

C++/CLI

Java

Python

public LineRemoveCommandEventArgs( 
   RasterImage image, 
   RasterRegion region, 
   int startRow, 
   int startColumn, 
   int length 
)

public LineRemoveCommandEvent( 
   Object source,  
   RasterImage image,  
   RasterRegion region,  
   int startRow,  
   int startColumn,  
   int length 
)

public: 
LineRemoveCommandEventArgs(  
   RasterImage^ image, 
   RasterRegion^ region, 
   int startRow, 
   int startColumn, 
   int length 
)

__init__(self,image,region,startRow,startColumn,length) # Overloaded constructor

Parameters

image
Affected image

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

startRow
The starting row of the line. The rows are zero-based.

startColumn
The starting column of the line. The columns are zero-based.

length
Length (in pixels) of the line.

Example

Run the LineRemoveCommand on an image.

Java

using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core;

   // Prepare the command 
   LineRemoveCommand command = new LineRemoveCommand(LineRemoveCommandFlags.UseGap | LineRemoveCommandFlags.CallBackRegion, 200, 5, 7, 10, 2, 2, LineRemoveCommandType.Horizontal); 
   command.LineRemove += new EventHandler<LineRemoveCommandEventArgs>(LineRemoveEvent_S4); 
   command.Run(image);

}
