   int brightness 
)

- (instancetype)initWithBrightness:(NSInteger)brightness NS_DESIGNATED_INITIALIZER;

   int brightness 
);

public: 
ChangeIntensityCommand(  
   int brightness 
)

__init__(self,brightness) # Overloaded constructor

Parameters

brightness
Amount to change the intensity. The intensity ranges from -1000 to 1000. A positive value increases (or lightens) the brightness of the image. A negative values decreases (or darkens) the brightness of the image.

Example

Run the ChangeIntensityCommand on an image and increase its intensity.

Java

using Leadtools.Codecs;

public void ChangeIntensityConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Image1.jpg")); 
 
   // Prepare the command 
   ChangeIntensityCommand command = new ChangeIntensityCommand(250); 
   // Increase the brightness by 25 percent  of the possible range. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
