Leadtools.ImageProcessing.SpecialEffects Namespace : PointillistCommand Class



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

Syntax

Visual Basic (Declaration)  
Public Class PointillistCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage) Copy Code
Dim instance As PointillistCommand
C#  
public class PointillistCommand : RasterCommand, IRasterCommand 
C++/CLI  
public ref class PointillistCommand : public RasterCommand, IRasterCommand 

Example

Run the PointillistCommand on an image.

Visual Basic Copy Code
Public Sub PointillistCommandExample()
   RasterCodecs.Startup()
   Dim codecs As New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg")

   ' Prepare the command
   Dim command As New PointillistCommand
   command.Size = 25
   command.FillColor = New RasterColor(255, 255, 255)
   command.Flags = PointillistCommandFlags.BackGroundColor Or PointillistCommandFlags.Point
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void PointillistCommandExample() 
{ 
   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.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, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

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- 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.
  • 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.
