using Leadtools.ImageProcessing.Core; 
 
 
public void SelectDataCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg")); 
 
   // Prepare the command 
   SelectDataCommand command = new SelectDataCommand(); 
   command.Color = new RasterColor(233, 10, 77); 
   command.Combine = true; 
   command.SourceLowBit = 2; 
   command.SourceHighBit = 6; 
   command.Threshold = 25; 
 
   command.Run(image); 
   codecs.Save(command.DestinationImage, Path.Combine(LEAD_VARS.ImagesDir, "SelectDataResult.Bmp"), RasterImageFormat.Bmp, 24);
