'Declaration
 
Public Class RomanMosaicCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As RomanMosaicCommand

public sealed class RomanMosaicCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.RomanMosaicCommand()

public ref class RomanMosaicCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

Remarks

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- 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.
