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

C++/CLI

Python

public class PointillistCommand : RasterCommand

public ref class PointillistCommand : public RasterCommand

class PointillistCommand(RasterCommand):

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.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void PointillistCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Image2.jpg")); 
 
   // Prepare the command 
   PointillistCommand command = new PointillistCommand(); 
   command.Size = 25; 
   command.FillColor = new RasterColor(255, 255, 255); 
   command.Flags = PointillistCommandFlags.BackGroundColor | PointillistCommandFlags.Point; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
