DotRemoveCommandEventArgs Constructor

Summary

Initializes a new DotRemoveCommand with explicit parameters.

Syntax

C++/CLI

Java

Python

public DotRemoveCommandEventArgs( 
   RasterImage image, 
   RasterRegion region, 
   LeadRect boundingRectangle, 
   int whiteCount, 
   int blackCount 
)

public DotRemoveCommandEvent( 
   Object source,  
   RasterImage image,  
   RasterRegion region,  
   LeadRect boundingRectangle,  
   int whiteCount,  
   int blackCount 
)

public: 
DotRemoveCommandEventArgs(  
   RasterImage^ image, 
   RasterRegion^ region, 
   LeadRect boundingRectangle, 
   int whiteCount, 
   int blackCount 
)

__init__(self,image,region,boundingRectangle,whiteCount,blackCount) # Overloaded constructor

Parameters

image
RasterImage object that references the image to be modified.

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

boundingRectangle
The bounding rectangle of the dot being processed.

whiteCount
Total number of white pixels in the dot being processed.

blackCount
Total number of black pixels in the dot being processed.

Example

Run the DotRemoveCommand on an image.

Java

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

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   DotRemoveCommand command = new DotRemoveCommand(DotRemoveCommandFlags.UseSize | DotRemoveCommandFlags.CallBackRegion, 1, 1, 10, 10); 
   command.DotRemove += new EventHandler<DotRemoveCommandEventArgs>(DotRemoveEvent_S4); 
   command.Run(image); 
 
}
