Summary

Initializes a new ZoomWaveCommand class object with explicit parameters.

Syntax
C#
VB
C++
  
Public Function New( _ 
   ByVal amplitude As Integer, _ 
   ByVal frequency As Integer, _ 
   ByVal phase As Integer, _ 
   ByVal zoomFactor As Integer, _ 
   ByVal centerPoint As LeadPoint, _ 
   ByVal fillColor As RasterColor, _ 
   ByVal type As ZoomWaveCommandType _ 
) 
public: 
ZoomWaveCommand(  
   int amplitude, 
   int frequency, 
   int phase, 
   int zoomFactor, 
   LeadPoint centerPoint, 
   RasterColor fillColor, 
   ZoomWaveCommandType type 
) 

Parameters

amplitude
Zoom wave magnitude.

frequency
The number of repeated waves along the radial line. This parameter only accepts positive values.

phase
Wave phase shift. The valid range is from -36000 to 36000. The real value is divided by 100.

zoomFactor
The percentage the wave grows as it moves from the image center. The valid range is from 0 to 100.

centerPoint
Center point from which the wave is zoomed.

fillColor
RasterColor object that specifies the fill color for any exposed areas.

type
Flag that indicates how to handle exposed areas.

Example

Run the ZoomWaveCommand on an image.

C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
public void ZoomWaveConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   ZoomWaveCommand command = new ZoomWaveCommand(20, 10, 0, 0, new LeadPoint(image.Width / 2, image.Height / 2), new RasterColor(0, 0, 0), ZoomWaveCommandType.Repeat); 
   // Apply zoom wave from center of the image. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images"; 
}

   ' Prepare the command 
   Dim command As ZoomWaveCommand = New ZoomWaveCommand(20, 10, 0, 0, New LeadPoint(leadImage.Width \ 2, leadImage.Height \ 2), New RasterColor(0, 0, 0), ZoomWaveCommandType.Repeat) 
   ' Apply zoom wave from center of the image. 
   command.Run(leadImage) 
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24) 
 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
   Public Const ImagesDir As String = "C:\Users\Public\Documents\LEADTOOLS Images"
