Syntax

Objective-C

C++/CLI

Java

Python

public int Brightness { get; set; }

@property (nonatomic, assign) NSInteger brightness;

public int getBrightness(); 
public void setBrightness( 
   int intValue 
);

public: 
property int Brightness { 
   int get(); 
   void set (    int ); 
}

Brightness # get and set (ColorReplaceCommand)

Property Value

Amount to change the brightness, in tenths of a percent. Valid values range from -1000 to 1000. This value is divided internally by 10. Positive values increase (or lighten) the brightness of the image. Negative values decrease (or darken) the brightness of the image.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void ColorReplaceCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "cannon.jpg")); 
 
   // Prepare the command 
   ColorReplaceCommand command = new ColorReplaceCommand(); 
   ColorReplaceCommandColor[] data = new ColorReplaceCommandColor[1]; 
   data[0] = new ColorReplaceCommandColor(); 
   data[0].Color = new RasterColor(200, 0, 35); 
   data[0].Fuzziness = 100; 
   command.Colors = data; 
   command.Hue = 9000; 
   command.Saturation = 0; 
   command.Brightness = 0; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
