Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void KeyStoneCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
 
   LeadPoint[] PolyPoints = new LeadPoint[4]; 
 
   //The four corners of the polygon 
   PolyPoints[0] = new LeadPoint(94, 94); 
   PolyPoints[1] = new LeadPoint(306, 43); 
   PolyPoints[2] = new LeadPoint(318, 237); 
   PolyPoints[3] = new LeadPoint(98, 237); 
 
   //Prepare the command 
   KeyStoneCommand command = new KeyStoneCommand(); 
 
   command.PolygonPoints = PolyPoints; 
   //Apply  
   command.Run(image); 
 
   codecs.Save(command.TransformedImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), image.OriginalFormat, image.BitsPerPixel); 
}
