Gamma Property

Summary

Gets or sets a value 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 (ColorLevelCommandData)

Property Value

Value that represents the gamma value. This value is used to modify the midtones of the image. The value in this member is a 100 times the actual value. Therefore, if uGamma = 167 then the actual gamma value is 1.67. Likewise, if you want to use a gamma of 1.75, set this property to 175. The default value is DEFAULT_GAMMA, which is 100 (actual gamma value of 1.00) which does not change the gamma value of the image.

using Leadtools.ImageProcessing.Color; 
 
 
public void ColorLevelCommandExample()

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   ColorLevelCommandData blue = new ColorLevelCommandData(0, 255, 255, 0, 100);
