GammaCorrectExtendedCommand Constructor(int,GammaCorrectExtendedCommandType)

Summary

Initializes a new GammaCorrectExtendedCommand with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public GammaCorrectExtendedCommand( 
   int gamma, 
   GammaCorrectExtendedCommandType type 
)

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

public GammaCorrectExtendedCommand( 
   int gamma, 
   GammaCorrectExtendedCommandType type 
);

public: 
GammaCorrectExtendedCommand(  
   int gamma, 
   GammaCorrectExtendedCommandType type 
)

__init__(self,gamma,type) # Overloaded constructor

Parameters

gamma
Any value greater than 0 that represents the gamma value. This value is divided internally by 100.

type
Flag that indicates which color space to use.

Example

Run the GammaCorrectExtendedCommand on an image.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void GammaCorrectExtendedConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   // Apply gamma effect on image using the YUV color space and gamma value of 2.50 
   GammaCorrectExtendedCommand command = new GammaCorrectExtendedCommand(250, GammaCorrectExtendedCommandType.YuvSpace); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
