public void ChangeHeightExample(RasterImage image)
{
   Debug.WriteLine(string.Format("Height: {0}", image.Height));
   int newHeight = image.Height / 2;

Public Sub ChangeHeightExample(ByVal image As RasterImage)
   Debug.WriteLine(String.Format("Height: {0}", image.Height))
   Dim newHeight As Integer = image.Height / 2
   image.ChangeHeight(newHeight)
   Debug.WriteLine(String.Format("Height: {0}", image.Height))
   Debug.Assert(image.Height = newHeight)
   image.Dispose()
End Sub
