public InvertedTextCommand( 
   InvertedTextCommandFlags flags, 
   int minimumInvertWidth, 
   int minimumInvertHeight, 
   int minimumBlackPercent, 
   int maximumBlackPercent 
)

public InvertedTextCommand( 
   int flags,  
   int minimumInvertWidth,  
   int minimumInvertHeight,  
   int minimumBlackPercent,  
   int maximumBlackPercent 
)

public: 
InvertedTextCommand(  
   InvertedTextCommandFlags flags, 
   int minimumInvertWidth, 
   int minimumInvertHeight, 
   int minimumBlackPercent, 
   int maximumBlackPercent 
)

__init__(self,flags,minimumInvertWidth,minimumInvertHeight,minimumBlackPercent,maximumBlackPercent) # Overloaded constructor

Parameters

flags
Flags that determine the behavior of the inverted text removal process.

minimumInvertWidth
The minimum width of an area that is considered to be inverted text. If the InvertedTextCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

minimumInvertHeight
The minimum height of an area that is considered to be inverted text. If the InvertedTextCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

minimumBlackPercent
The minimum percent of total pixels in an inverted text area that must be black. Areas with a lower percent of black pixels are not considered.

maximumBlackPercent
The maximum percent of total pixels in an inverted text area that must be black. Areas with a higher percent of black pixels are not considered.

Example

Run the InvertedTextCommand on an image.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void InvertedTextConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   InvertedTextCommand command = new InvertedTextCommand(InvertedTextCommandFlags.UseDpi, 5000, 500, 70, 95); 
   command.InvertedText += new EventHandler<InvertedTextCommandEventArgs>(InvertedTextEvent_S2); 
   command.Run(image); 
 
}

   MessageBox.Show("Size " + "( " + e.BoundingRectangle.Left + ", " + e.BoundingRectangle.Top + ") - " + "( " + e.BoundingRectangle.Right + ", " + e.BoundingRectangle.Bottom + ")" +
