using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
using Leadtools.ImageProcessing.Color; 
 
public void InvertedPageCommandExample()

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

   string invertedImageFileName = Path.Combine(LEAD_VARS.ImagesDir, "ocr1_Inverted.tif"); 
   string nonInvertedImageFileName = Path.Combine(LEAD_VARS.ImagesDir, "ocr1_NonInverted.tif"); 
 
   RasterImage image = codecs.Load(tifFileName); 
 
   // The images should be non-inverted at the beginning, check 
   InvertedPageCommand invertedPage = new InvertedPageCommand(InvertedPageCommandFlags.NoProcess); 
   invertedPage.Run(image); 
   Console.WriteLine("Original image, inverted = {0}", invertedPage.IsInverted); 
 
   // Invert the image 
   InvertCommand invert = new InvertCommand(); 
   invert.Run(image); 
 
   codecs.Save(image, invertedImageFileName, image.OriginalFormat, image.BitsPerPixel); 
 
   // Check again 
   invertedPage.Run(image); 
   Console.WriteLine("After running InvertCommand, inverted = {0}", invertedPage.IsInverted); 
 
   // Now run the command to un-invert the image 
   invertedPage.Flags = InvertedPageCommandFlags.Process; 
   invertedPage.Run(image); 
 
   // Now check the image again 
   invertedPage.Flags = InvertedPageCommandFlags.NoProcess; 
   invertedPage.Run(image);
