Syntax
C#
C++/CLI
Python
public class DiffuseGlowCommand : RasterCommand 
public ref class DiffuseGlowCommand : public RasterCommand   
class DiffuseGlowCommand(RasterCommand): 
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:

    diffuseglowbefore.jpg
    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:

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

  • This method supports 12-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit 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.

public void DiffuseGlowCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   RasterColor fillColor = new RasterColor(255, 255, 255); 
   DiffuseGlowCommand command = new DiffuseGlowCommand(); 
   command.GlowAmount = 50; 
   command.ClearAmount = 50; 
   command.SpreadAmount = 10; 
   command.WhiteNoiseRange = 10; 
   command.GlowColor = fillColor; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
