Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
 
public void ScrambleCommandExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
	string scrambledFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1_scrambled.bmp"); 
	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 
	command.Flags = ScrambleCommandFlags.Decrypt; 
	command.Run(image); 
	codecs.Save(image, unscrambledFileName, RasterImageFormat.Bmp, 24); 
 
	// Clean Up 
	image.Dispose(); 
	codecs.Dispose();
