Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void AutoColorLevelConstructorExample_S1() 
{ 
   // 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 
   AutoColorLevelCommand command = new AutoColorLevelCommand(AutoColorLevelCommandType.Intensity, AutoColorLevelCommandFlags.None); 
   command.BlackClip = 100; 
   command.WhiteClip = 100; 
   // Apply "Auto Leveling" to the image. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
