	string unscrambledFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1_unscrambled.bmp"); 
 
	// Load the source image from disk 
	RasterImage image = codecs.Load(srcFileName); 
 
	LeadRect rc = new LeadRect(0, 0, image.Width / 2, image.Height / 2); 
	int key = 123; 
 
	// Scramble it and save it to disk 
	ScrambleCommand command = new ScrambleCommand(); 
	command.Flags = ScrambleCommandFlags.Encrypt; 
	command.Rectangle = rc; 
	command.Key = key; 
	command.Run(image); 
	codecs.Save(image, scrambledFileName, RasterImageFormat.Bmp, 24); 
 
	// Unscramble the image and save it to disk
