MosaicTilesCommand Class

Summary

Creates a mosaic effect on an image by dividing an image into rectangular or arc-shaped cells with irregular boundaries and modifying the color of each cell. This method is available in the Imaging Pro and above toolkits.

Syntax

C++

public class MosaicTilesCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

Public Class MosaicTilesCommand  
   Inherits Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand 
   Implements Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

public ref class MosaicTilesCommand : public Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

Remarks

This method makes an image look like a mosaic made from tiles. Tiles can be rectangular or arc-shaped, depending upon the coordinate system used to draw the tiles. The method's many parameters control factors like the border color, tile color, pen width, tile width and height, etc.
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 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.

Example

Run the MosaicTilesCommand on an image.
