Property Value

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
C#
Java
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void ChangeIntensityCommandExample() 
{ 
   // 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(); 
   //Increase the brightness by 25 percent  of the possible range. 
   command.Brightness = 250; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
