Syntax

Objective-C

C++/CLI

Java

Python

public int RightMargin {get; set;}

@property (nonatomic, assign) NSUInteger rightMargin;

public int getRightMargin(); 
public void setRightMargin( 
   int intValue 
);

public: 
property int RightMargin { 
   int get(); 
   void set (    int ); 
}

RightMargin # get and set (BlankPageDetectorCommand)

Property Value

Number of units to exclude from the right edge of the image. Possible values range from 0 to the image's width, units determined by the value specified in Flags. Units of measure such as inches or centimeters can be used by enabling the corresponding BlankPageDetectorCommandFlags.

Example

Runs the BlankPageDetectorCommand on an image and determines whether it is blank.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void BlankPageDetectorCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   BlankPageDetectorCommand command = new BlankPageDetectorCommand() 
   { 
      // The following properties can be left to their defaults or set to desired values: 
      LeftMargin = 0, 
      TopMargin = 0, 
      RightMargin = 0, 
      BottomMargin = 0, 
      MinimumTextSize = 0 
   }; 
 
   //Determine whether the image is a blank page 
   command.Flags = BlankPageDetectorCommandFlags.DetectNoisyPage; 
   command.Run(image); 
 
   MessageBox.Show(" Is Blank   : " + command.IsBlank + "\n Accuracy : " + (command.Accuracy * 1.0 / 100) + "%", "Blank Page Detection Results"); 
 
}
