'Declaration
 
Public Class DiffuseGlowCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As DiffuseGlowCommand

public sealed class DiffuseGlowCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.DiffuseGlowCommand()

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

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
SpreadAmount	10
WhiteNoiseRange	10
GlowColor	white

The following figure results:

If the image has a region, the effect will be applied on the region only.
This method 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 method does not support signed data images.
This command does not support 32-bit grayscale images.
