using Leadtools.ImageProcessing; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void SubtractBackgroundCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Image4.Tif")); 
 
   // Prepare the command 
   SubtractBackgroundCommand command = new SubtractBackgroundCommand(); 
   command.RollingBall = 50; 
   command.BrightnessFactor = 100; 
   command.ShrinkingSize = SubtractBackgroundCommandType.DependOnRollingBallSize; 
   command.Flags = SubtractBackgroundCommandFlags.BackgroundIsDarker; 
   //Apply Subtract Background effect on the image. 
   command.Run(image);
