Adds many spots of directed light sources to the image. This command is available in the Raster Pro and above toolkits.

Object Model


Syntax

Visual Basic (Declaration)  
Public Class LightCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage) Copy Code
Dim instance As LightCommand
C#
