Leadtools.ImageProcessing.SpecialEffects Namespace : WaveCommand Class



Distorts the image with two perpendicular waves at the specified angle and with the specified wave type. This command is available in the Raster Pro and above toolkits.

Syntax

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

Example

Run the WaveCommand on an image.

Visual Basic Copy Code
Public Sub WaveCommandExample()
   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 WaveCommand = New WaveCommand
   command.Amplitude = 20
   command.Angle = 0
   command.FillColor = New RasterColor(0, 0, 0)
   command.Flags = WaveCommandFlags.Repeat Or WaveCommandFlags.Period Or WaveCommandFlags.SinWave
   command.HorizontalFactor = 100
   command.VerticalFactor = 100
   command.WaveLength = 25
   'apply sinusoidal waves on the image.
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void WaveCommandExample() 
{ 
   // 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 
   WaveCommand command = new WaveCommand(); 
   command.Amplitude = 20; 
   command.Angle = 0; 
   command.FillColor = new RasterColor(0, 0, 0); 
   command.Flags = WaveCommandFlags.Repeat | WaveCommandFlags.Period | WaveCommandFlags.SinWave; 
   command.HorizontalFactor = 100; 
   command.VerticalFactor = 100; 
   command.WaveLength = 25; 
   //apply sinusoidal waves on the image. 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • The command applies two perpendicular waves. The horizontal factor and vertical factor values control the size of these waves.
  • 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.
