   ' Prepare the command
   Dim command As CylinderCommand = New CylinderCommand
   command.Value = 100
   command.Type = CylinderCommandType.Horizontal
   ' Warp the image to horizontal cylinder shape.
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void CylinderCommandExample() 
{ 
   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg"); 
 
   // Prepare the command 
   CylinderCommand command = new CylinderCommand(); 
   command.Value = 100; 
   command.Type = CylinderCommandType.Horizontal; 
   // Warp the image to horizontal cylinder shape. 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}
