Leadtools.ImageProcessing.SpecialEffects Namespace : CloudsCommand Class



Applies cloud effects to a bitmap. This method is available in the Raster Pro and above toolkits.

Syntax

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

Example

Run the CloudsCommand on an image.

Visual Basic Copy Code
Public Sub CloudsCommandExample()
   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 CloudsCommand = New CloudsCommand
   command.Seed = 1000
   command.Frequency = 4
   command.Density = 10
   command.Opacity = 10
   command.BackColor = New RasterColor(255, 255, 255)
   command.CloudsColor = New RasterColor(0, 0, 0)
   command.Type = CloudsCommandType.Difference
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void CloudsCommandExample() 
{ 
   // 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 
   CloudsCommand command = new CloudsCommand(); 
   command.Seed        = 1000; 
   command.Frequency   = 4; 
   command.Density     = 10; 
   command.Opacity     = 10; 
   command.BackColor   = new RasterColor(255,255,255); 
   command.CloudsColor = new RasterColor(0,0,0); 
   command.Type        = CloudsCommandType.Difference; 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • 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.
  • The Seed property gives the user the ability to change the shape of the clouds effect by changing the starting point for the clouds randomization process. If the user applies the effect many times with the same value of the Seed property the shape of the clouds will be the same.
  • 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.
