{
	private GcZoom _gcZoom1 = new GcZoom();

	public GcZoomAnimationDemo()
	{
		_gcZoom1.Target = this;
		_gcZoom1.AnimationStarting += _gcZoom1_AnimationStarting;
	}

	void _gcZoom1_AnimationStarting(object sender, AnimationStartingEventArgs e)
	{
		if (_customizeDuringChB.Checked)
		{
			e.Duration = e.Duration * 4; // Make the animation slower.

			// e.Cancel = true;  // If it is necessary, cancel the animation by this code.
		}
		Console.WriteLine("+++ _gcZoom1_AnimationStarting +++");
		Console.WriteLine("CurrentScrollLocation:   " + e.CurrentScrollLocation.ToString());
		Console.WriteLine("CurrentZoomFactor:       " + e.CurrentZoomFactor.ToString());
		Console.WriteLine("TargetScrollLocation:    " + e.TargetScrollLocation.ToString());
		Console.WriteLine("TargetZoomFactor         " + e.TargetZoomFactor.ToString());
	}
}
