public ref class RomanMosaicCommand : public RasterCommand   
  • Use this method to divide the image into rectangular or rounded rectangular tiles and then fill each tile with a color chosen randomly from the colors of each tile's pixels.
  • This method can process the whole image or a region of the image. If the image has a region, the effect is applied only to the region.
  • 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.

Run the RomanMosaicCommand on an image.
