Leadtools.ImageProcessing.SpecialEffects Namespace : ColoredBallsCommand Class




Throws colored balls over the image. The resulting color of the ball is a combination of ball color and the color of the pixel where it has fallen with certain opacity. Various parameters control the color and appearance of the balls. This method is available in the Document/Medical toolkits.

Remarks

  • 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.
  • If the image has a region, this method works only on the region. If the image does not have a region, this method works on the entire image.
  • This method does not support signed data images.
  • This command does not support 32-bit grayscale images.
