Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void LightCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   LightCommandData[] Data = new LightCommandData[1]; 
   Data[0].Angle = 0; 
   Data[0].CenterPoint = new LeadPoint(image.Width / 2, image.Height / 2); 
   Data[0].Edge = 0; 
   Data[0].Brightness = 100; 
   Data[0].FillColor = new RasterColor(255, 255, 255); 
   Data[0].Height = Math.Min(image.Height, image.Width) / 2; 
   Data[0].Width = Math.Min(image.Height, image.Width) / 2; 
   Data[0].Opacity = 100; 
   Data[0].Type = LightCommandType.Spot; 
 
   LightCommand command = new LightCommand(); 
   command.Ambient = 100; 
   command.Bright = 100; 
   command.Data = Data; 
   command.AmbientColor = new RasterColor(255, 255, 255); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
