using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Core;

   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "glare.jpg")); 
   string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "BinarizedImage.bmp"); 
 
   // Prepare the command 
   SauvolaBinarizeCommand command = new SauvolaBinarizeCommand(); 
 
   command.KFactor = 0.15; 
   command.RFactor = 128; 
   command.WindowSize = 55; 
 
   command.Run(image); 
 
    // Save it to disk 
    codecs.Save(image, destFileName, RasterImageFormat.Bmp, 24);
