public ref class DiffuseGlowCommand : public RasterCommand   
  • This command adds pixels randomly to the image. A glow is added based on a combination of the pixel colors and the glow color.
  • As an example, if you use the following image:

    And you were to call DiffuseGlowCommand using the following settings:

    Parameter Value
    GlowAmount 50
    ClearAmount 50

    GlowColor white

    The following figure results:


  • If the image has a region, the effect will be applied on the region only.
