PointillistCommand Class

Summary

Converts image colors into randomly placed dots to create a pointillist painting. This command is available in the Imaging Pro and above toolkits.

Syntax

WinRT C#

C++

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

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

public sealed class PointillistCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.PointillistCommand()

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

Remarks

Pointillism is a painting technique where the image is composed of tiny, separate dots of primary color. Non-primary colors are created by placing primary colors beside each other and allowing the "mixing" to be performed when the image is viewed.
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.
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.

Example

Run the PointillistCommand on an image.
