LensFlareCommand Class

Summary

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 Imaging Pro and above toolkits.

Syntax

WinRT C#

C++

public class LensFlareCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

Public Class LensFlareCommand  
   Inherits Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand 
   Implements Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

public sealed class LensFlareCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.LensFlareCommand()

public ref class LensFlareCommand : public Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

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-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit 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.

For more information, refer to Correcting Colors.

Example

Run the LensFlareCommand on an image.
