Leadtools.ImageProcessing.SpecialEffects Namespace : DryCommand Class



Simulates painting an image with the watercolor dry brush technique. This command is available in the Raster Pro and above toolkits.

Syntax

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

Example

Run the DryCommand on an image with a neighborhood Dimensions = 5x5 pixels.

Visual Basic Copy Code
Public Sub DryCommandExample()
   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 DryCommand = New DryCommand
   command.Dimension = 5
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void DryCommandExample() 
{ 
   // 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 
   DryCommand command = new DryCommand(); 
   command.Dimension = 5; 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • This command simulates what would happen if the image had just been painted with paints and the paints were allowed to dry. The colors become darker, with less brightness.
  • The effect can be controlled by specifying the size of the neighborhood that is used for calculating each pixel value.
  • If the image has a region, the effect will be applied on the region only.
  • This command 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 command does not support signed data images.
  • This command does not support 32-bit grayscale images.
