Remarks

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.

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   RasterColor fillColor = new RasterColor(255, 255, 255);
