Contrast Property

Summary

Gets or sets the fraction of contrast enhancement applied to the image.

Syntax

Objective-C

C++/CLI

Java

Python

public int Contrast { get; set; }

@property (nonatomic, assign) NSUInteger contrast;

public int getContrast(); 
public void setContrast( 
   int intValue 
);

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

Contrast # get and set (MultiscaleEnhancementCommand)

Property Value

Fraction of contrast enhancement applied to the image. Valid values range from 0 - 10000, which are interpreted as 0 percent - 100 percent. This value is internally divided by 10000. Greater values will produce stronger contrast.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
 
public void MultiScaleEnhancementCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
 
   // Prepare the command 
   MultiscaleEnhancementCommand command = new MultiscaleEnhancementCommand(); 
   command.Contrast = 2000; 
   command.EdgeLevels = 4; 
   command.EdgeCoefficient = -1; 
   command.LatitudeLevels = 0; 
   command.LatitudeCoefficient = 0; 
   command.Type = MultiscaleEnhancementCommandType.Gaussian; 
   command.Flags = MultiscaleEnhancementCommandFlags.EdgeEnhancement; 
   // Apply multiscale enhancement 
   command.Run(image); 
 
}
