Leadtools.ImageProcessing.SpecialEffects Namespace : ZoomWaveCommand Class



Distorts the image with a wave zoomed from the specified center. This command is available in the Raster Pro and above toolkits.

Syntax

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

Example

Run the ZoomWaveCommand on an image.

Visual Basic Copy Code
Public Sub ZoomWaveCommandExample()
   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 ZoomWaveCommand = New ZoomWaveCommand
   command.Amplitude = 20
   ' Apply zoom wave from center of the image.
   command.CenterPoint = New Point(leadImage.Width \ 2, leadImage.Height \ 2)
   command.FillColor = New RasterColor(0, 0, 0)
   command.Frequency = 10
   command.Phase = 0
   command.ZoomFactor = 0
   command.Type = ZoomWaveCommandType.Repeat
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void ZoomWaveCommandExample() 
{ 
   // 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 
   ZoomWaveCommand command = new ZoomWaveCommand(); 
   command.Amplitude   = 20; 
   // Apply zoom wave from center of the image. 
   command.CenterPoint = new Point(image.Width / 2, image.Height / 2); 
   command.FillColor   = new RasterColor(0, 0, 0); 
   command.Frequency   = 10; 
   command.Phase       = 0; 
   command.ZoomFactor  = 0; 
   command.Type        = ZoomWaveCommandType.Repeat; 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • The command applies a sinusoidal wave zoomed from the specified center. The center point must be defined inside the image, or inside the region, if the image has a region.
  • 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.
