Amplitudes Property

Summary

Gets or sets an array of integers that represent wave values.

Syntax

C++/CLI

Python

public int[] Amplitudes { get; set; }

public: 
property array<int>^ Amplitudes { 
   array<int>^ get(); 
   void set (    array<int>^ ); 
}

Amplitudes # get and set (FreeHandWaveCommand)

Property Value

Array of integers that represent wave values. The real value of the array elements is divided by 1000, and the valid value of each element in the array is between -1000 and 1000. These values are generally obtained from the Leadtools.ImageProcessing.Effects.EffectsUtilities.GetCurvePoints(System.Int32[],Leadtools.LeadPoint[],Leadtools.ImageProcessing.Effects.CurvePointsType) utility method. They may also be obtained through the FreeHandWave Dialog.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void FreeHandWaveCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   LeadPoint[] UserPoint = new LeadPoint[4]; 
   int[] Amplitudes = new int[13]; 
 
   FreeHandWaveCommand command = new FreeHandWaveCommand(); 
 
   // Fill UserPoint array with points that define a triangular wave 
   UserPoint[0].X = 0; 
   UserPoint[0].Y = 0; 
   UserPoint[1].X = 3; 
   UserPoint[1].Y = 10; 
   UserPoint[2].X = 9; 
   UserPoint[2].Y = -10; 
   UserPoint[3].X = 12; 
   UserPoint[3].Y = 0; 
 
   //Draw a triangular wave according to UserPoint points and store the Amplitudes values in the Amplitudes array. 
   EffectsUtilities.GetCurvePoints(Amplitudes, UserPoint, CurvePointsType.Linear); 
 
   command.Amplitudes = Amplitudes; 
   command.Scale = 100; 
   command.WaveLength = 10; 
   command.Angle = 0; 
   command.FillColor = new RasterColor(0, 0, 0); 
   command.Flags = FreeHandWaveCommandFlags.Repeat | FreeHandWaveCommandFlags.Frequency; 
   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:\LEADTOOLS22\Resources\Images";
