'Declaration
 
Public Class LensFlareCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand

'Usage
 
Dim instance As LensFlareCommand

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

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.
