The Wave effect distorts the image as if it had been disturbed by a number of random waves.

 

   

Settings
 
Name Default Description
Number 3

The number of random waves that should be generated.

LengthMin 40 pixels

The minimum wavelength for a random wave.

LengthMax 60 pixels The maximum wavelength for a random wave.
HeightMin 5 pixels The minimum amplitude for a random wave.
HeightMax 15 pixels The maximum amplitude for a random wave.
Speed 6 There is a general speed versus quality tradeoff. Higher values produce faster results at the expense of quality.

 

   

Workings
 

The effect distorts the image as if it had been disturbed by a number of waves. By choosing appropriate values you can make images look like they are underwater or are being seen through a heat haze.

 

   

Example
 

The following examples show the effect of a Wave applied with a number of different settings.

[C#]
void function() {
  using (Doc doc = new Doc()) {
    AddImagePage(doc, img3); // original image
    doc.Rendering.Save("EffectWave.jpg");
    using (ImageLayer layer = AddImagePage(doc, img3)) {
      using (EffectOperation effect = new EffectOperation("Wave")) {
        effect.Apply(layer.PixMap);
      }
    }
    doc.Rendering.Save("EffectWaveDefault.jpg");
    using (ImageLayer layer = AddImagePage(doc, img3)) {
      using (EffectOperation effect = new EffectOperation("Wave")) {
        effect.Parameters["LengthMin"].Value = 15;
        effect.Parameters["LengthMax"].Value = 30;
        effect.Apply(layer.PixMap);
      }
    }
    doc.Rendering.Save("EffectWaveLength.jpg");
    using (ImageLayer layer = AddImagePage(doc, img3)) {
      using (EffectOperation effect = new EffectOperation("Wave")) {
        effect.Parameters["HeightMin"].Value = 0;
        effect.Parameters["HeightMax"].Value = 5;
        effect.Apply(layer.PixMap);
      }
    }
    doc.Rendering.Save("EffectWaveHeight.jpg");
  }
}

[Visual Basic]
Sub ...
  Using doc As New Doc()
    AddImagePage(doc, img3)
    ' original image
    doc.Rendering.Save("EffectWave.jpg")
    Using layer As ImageLayer = AddImagePage(doc, img3)
      Using effect As New EffectOperation("Wave")
        effect.Apply(layer.PixMap)
      End Using
    End Using
    doc.Rendering.Save("EffectWaveDefault.jpg")
    Using layer As ImageLayer = AddImagePage(doc, img3)
      Using effect As New EffectOperation("Wave")
        effect.Parameters("LengthMin").Value = 15
        effect.Parameters("LengthMax").Value = 30
        effect.Apply(layer.PixMap)
      End Using
    End Using
    doc.Rendering.Save("EffectWaveLength.jpg")
    Using layer As ImageLayer = AddImagePage(doc, img3)
      Using effect As New EffectOperation("Wave")
        effect.Parameters("HeightMin").Value = 0
        effect.Parameters("HeightMax").Value = 5
        effect.Apply(layer.PixMap)
      End Using
    End Using
    doc.Rendering.Save("EffectWaveHeight.jpg")
  End Using
End Sub

 


Original Image before Wave


After Wave with default settings


LengthMin = 15, LengthMax = 30


HeightMin = 0, HeightMax = 5
