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:
    ParameterValue
    GlowAmount50
    ClearAmount50
    SpreadAmount10
    WhiteNoiseRange10
    GlowColorwhite

    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.
