Leadtools.ImageProcessing.SpecialEffects Namespace : ZigZagCommand Class



Radially distorts the image by creating waves that twist the image around a specified center. This command is available in the Raster Pro and above toolkits.

Syntax

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

Example

Run the ZigZagCommand on an image and applies the ZigZag filter.

Visual Basic Copy Code
Public Sub ZigZagCommandExample()
   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 ptCenter As Point = New Point(192, 82)
   Dim fillColor As RasterColor = New RasterColor(0, 0, 0)
   Dim command As ZigZagCommand = New ZigZagCommand

   command.Amplitude = 47
   command.Attenuation = 92
   command.Frequency = 13
   command.Phase = -162
   command.CenterPoint = ptCenter
   command.FillColor = fillColor
   command.Flags = ZigZagCommandFlags.Color Or ZigZagCommandFlags.RadialWave
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()

   command.Frequency = 13; 
   command.Phase = -162; 
   command.CenterPoint = ptCenter; 
   command.FillColor = fillColor;

Remarks

  • As an example, if you use the following image:

    And you were to call ZigZagCommand using the following settings:
    Parameter Value
    Amplitude 47
    Attenuation 92
    Frequency 13
    Phase -162
    CenterPoint (192, 82)
    FillColor Black
    Flags Color | RadialWave

    The following figure results:

    As another settings, if you use the same settings except you use the PondRippleWave flag, the following figure results:
  • 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.
