GammaCorrectCommand Constructor(int)

Summary

Initializes a new GammaCorrectCommand class object with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public GammaCorrectCommand( 
   int gamma 
)

- (instancetype)initWithGamma:(NSUInteger)gamma NS_DESIGNATED_INITIALIZER;

public GammaCorrectCommand( 
   int gamma 
);

public: 
GammaCorrectCommand(  
   int gamma 
)

__init__(self,gamma) # Overloaded constructor

Parameters

gamma
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

Run the GammaCorrectCommand on an image and apply gamma correction.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void GammaCorrectConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   //Set a gamma value of 2.5. 
   GammaCorrectCommand command = new GammaCorrectCommand(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:\LEADTOOLS22\Resources\Images";
