[C#]
void function() {
  using (Doc doc = new Doc()) {
    AddImagePage(doc, img3); // original image
    doc.Rendering.Save("EffectPinch.jpg");
    using (ImageLayer layer = AddImagePage(doc, img3)) {
      using (EffectOperation effect = new EffectOperation("Pinch")) {
        effect.Apply(layer.PixMap);
      }
    }
    doc.Rendering.Save("EffectPinchDefault.jpg");
    using (ImageLayer layer = AddImagePage(doc, img3)) {
      using (EffectOperation effect = new EffectOperation("Pinch")) {
        effect.Parameters["Amount"].Value = 75;
        effect.Apply(layer.PixMap);
      }
    }
    doc.Rendering.Save("EffectPinchAmount75.jpg");
    using (ImageLayer layer = AddImagePage(doc, img3)) {
      using (EffectOperation effect = new EffectOperation("Pinch")) {
        effect.Parameters["Extent"].Value = 100;
        effect.Apply(layer.PixMap);
      }
    }
    doc.Rendering.Save("EffectPinchExtent100.jpg");
  }
}

[Visual Basic]
Sub ...
  Using doc As New Doc()
    AddImagePage(doc, img3)
    ' original image
    doc.Rendering.Save("EffectPinch.jpg")
    Using layer As ImageLayer = AddImagePage(doc, img3)
      Using effect As New EffectOperation("Pinch")
        effect.Apply(layer.PixMap)
      End Using
    End Using
    doc.Rendering.Save("EffectPinchDefault.jpg")
    Using layer As ImageLayer = AddImagePage(doc, img3)
      Using effect As New EffectOperation("Pinch")
        effect.Parameters("Amount").Value = 75
        effect.Apply(layer.PixMap)
      End Using
    End Using
    doc.Rendering.Save("EffectPinchAmount75.jpg")
    Using layer As ImageLayer = AddImagePage(doc, img3)
      Using effect As New EffectOperation("Pinch")
        effect.Parameters("Extent").Value = 100
        effect.Apply(layer.PixMap)
      End Using
    End Using
    doc.Rendering.Save("EffectPinchExtent100.jpg")
  End Using
End Sub

Original Image before Pinch

After Pinch with default settings

Amount = 75

Extent = 100
