Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Core; 
 
public void AlignImagesCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage ReferenceImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "cannon.jpg")); 
 
   //Rotate the image to be registered 
   RasterImage TemplateImage = new RasterImage(ReferenceImage); 
   RotateCommand command = new RotateCommand(45 * 100, RotateCommandFlags.Bicubic, new RasterColor(0, 0, 0)); 
   command.Run(TemplateImage); 
 
   //Get feature points from the two images that correspond to each other. 
   LeadPoint[] templatePoints = new LeadPoint[2]; 
   LeadPoint[] referencePoints = new LeadPoint[2]; 
 
   referencePoints[0] = new LeadPoint(173, 102); 
   referencePoints[1] = new LeadPoint(216, 259); 
 
   templatePoints[0] = new LeadPoint(239, 66); 
   templatePoints[1] = new LeadPoint(158, 207); 
 
   //Prepare the command 
   AlignImagesCommand alignCommand = new AlignImagesCommand(); 
 
   alignCommand.TemplateImage = TemplateImage; 
   alignCommand.ReferenceImagePoints = referencePoints; 
   alignCommand.TemplateImagePoints = templatePoints; 
   alignCommand.RegistrationMethod = RegistrationOptions.Unknown; 
 
   //Apply 
   alignCommand.Run(ReferenceImage); 
 
   // Save the resulting image 
   codecs.Save(alignCommand.RegisteredImage, Path.Combine(LEAD_VARS.ImagesDir, "RegisteredImage.bmp"), RasterImageFormat.Bmp, 24);
