Run the BendCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void BendCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   BendCommand command = new BendCommand(); 
   command.Value = 100; 
   // bend the image around it is center. 
   command.CenterPoint = new LeadPoint(image.Width / 2, image.Height / 2); 
   command.Flags = BendCommandFlags.Repeat | BendCommandFlags.WithoutRotate | BendCommandFlags.Normal; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
