Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void GammaCorrectExtendedCommandExample()

   // Load an image 
   RasterCodecs codecs = new RasterCodecs();

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   GammaCorrectExtendedCommand command = new GammaCorrectExtendedCommand(); 
 
   // Apply gamma effect on image using the YUV color space and gamma value of 2.50 
   command.Gamma = 250; 
   command.Type = GammaCorrectExtendedCommandType.YuvSpace; 
   command.Run(image);
