InvertedTextCommandEventArgs Constructor

Summary

Initializes a new InvertedTextCommand class object with explicit parameters.

Syntax

C++/CLI

Java

Python

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

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

public: 
InvertedTextCommandEventArgs(  
   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 affected image.

region
LEADTOOLS RasterRegion representing the inverted text to be removed. Dispose of this region when it is no longer needed.

boundingRectangle
The bounding rectangle of the inverted text region being processed.

whiteCount
Total number of white pixels in the inverted text region being processed.

blackCount
Total number of black pixels in the inverted text region being processed.

Example

Runs the InvertedTextCommand on an image.

Java

using Leadtools.Codecs;

   // Prepare the command 
   InvertedTextCommand command = new InvertedTextCommand(InvertedTextCommandFlags.UseDpi | InvertedTextCommandFlags.CallBackRegion, 5000, 500, 70, 95); 
   command.InvertedText += new EventHandler<InvertedTextCommandEventArgs>(InvertedTextEvent_S4); 
   command.Run(image); 
 
}
