Leadtools.ImageProcessing.SpecialEffects Namespace : LensFlareCommand Class



Simulates the secondary reflections caused when bright lights are facing the camera lens. The lens flare is refracted into a series of lightened circles that surround the flare. This method is available in the Raster Pro and above toolkits.

Object Model

Public Sub LensFlareCommandExample()
   Dim codecs As New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg"))

   ' Prepare the command
   Dim command As LensFlareCommand = New LensFlareCommand
   'Set the center point in the middle of the first square.
   command.CenterPoint = New LeadPoint(leadImage.Width \ 4, leadImage.Height \ 4)
   command.Brightness = 100
   command.Type = LensFlareCommandType.Type1
   command.Color = New RasterColor(100, 150, 10)
   ' Apply the lens flare effect to the image.

      command.Run(image);
      codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);

   }

Remarks

  • Secondary reflections are caused when bright lights are facing the camera lens. These reflections can show up as spots or banding. The command adds this effect to the image by controlling their number, position, brightness and size of the spots or banding. Each lens type has its own spot distribution and ray thickness.
  • This command supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support signed data images.
  • For an example, see the following figure:

  • The following figure shows the same image, after the effect has been applied:

  • This command does not support 32-bit grayscale images.
