Gamma Property

Summary

Gets or sets an integer that represents the gamma value.

Syntax

Objective-C

C++/CLI

Java

Python

public int Gamma { get; set; }

@property (nonatomic, assign) NSUInteger gamma;

public int getGamma(); 
public void setGamma( 
   int intValue 
);

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

Gamma # get and set (GammaCorrectCommand)

Property Value

Integer that represents the gamma value. It can be any number greater than 0. Because this is an unsigned integer (Integer with values greater than 0), it is 100 times the actual gamma value. For example, use 235 to set a gamma value of 2.35.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void GammaCorrectCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   GammaCorrectCommand command = new GammaCorrectCommand(); 
   //Set a gamma value of 2.5. 
   command.Gamma = 250; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
