Summary

Initializes a new ChangeIntensityCommand class object with explicit parameters.

Syntax

Objective-C

C++

Java

public ChangeIntensityCommand( 
   int brightness 
)

Public Function New( _ 
   ByVal brightness As Integer _ 
)

- (instancetype)initWithBrightness:(NSInteger)brightness

public ChangeIntensityCommand(int brightness)

public: 
ChangeIntensityCommand(  
   int brightness 
)

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.

   // 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);
