RippleEffect

The Pinch effect distorts the image as if it had been rippled.

The effect is very similar to a pond ripple. The image is distorted as if it was projected onto the surface of a pond and then a stone had been dropped into the middle.

The following example images show the effect of a Ripple filter applied to a picture with different settings.

[C#]
void function() {
  using (Doc doc = new Doc()) {
    AddImagePage(doc, img3); // original image
    doc.Rendering.Save("EffectRipple.jpg");
    using (ImageLayer layer = AddImagePage(doc, img3)) {
      using (EffectOperation effect = new EffectOperation("Ripple")) {
        effect.Apply(layer.PixMap);
      }
    }
    doc.Rendering.Save("EffectRippleDefault.jpg");
    using (ImageLayer layer = AddImagePage(doc, img3)) {
      using (EffectOperation effect = new EffectOperation("Ripple")) {
        effect.Parameters["Height"].Value = 15;
        effect.Apply(layer.PixMap);
      }
    }
    doc.Rendering.Save("EffectRippleHeight15.jpg");
    using (ImageLayer layer = AddImagePage(doc, img3)) {
      using (EffectOperation effect = new EffectOperation("Ripple")) {
        effect.Parameters["Length"].Value = 10;
        effect.Apply(layer.PixMap);
      }
    }
    doc.Rendering.Save("EffectRippleLength10.jpg");
  }
}

[Visual Basic]
Sub ...
  Using doc As New Doc()
    AddImagePage(doc, img3)
    ' original image
    doc.Rendering.Save("EffectRipple.jpg")
    Using layer As ImageLayer = AddImagePage(doc, img3)
      Using effect As New EffectOperation("Ripple")
        effect.Apply(layer.PixMap)
      End Using
    End Using
    doc.Rendering.Save("EffectRippleDefault.jpg")
    Using layer As ImageLayer = AddImagePage(doc, img3)
      Using effect As New EffectOperation("Ripple")
        effect.Parameters("Height").Value = 15
        effect.Apply(layer.PixMap)
      End Using
    End Using
    doc.Rendering.Save("EffectRippleHeight15.jpg")
    Using layer As ImageLayer = AddImagePage(doc, img3)
      Using effect As New EffectOperation("Ripple")
        effect.Parameters("Length").Value = 10
        effect.Apply(layer.PixMap)
      End Using
    End Using
    doc.Rendering.Save("EffectRippleLength10.jpg")
  End Using
End Sub

Original Image before Ripple

After Ripple with default settings

Height = 15

Length = 10
