Converting XAML element to Image in silverlight?

Question

我有一个XAML canvas元素，我需要将canvas元素及其中的任何内容保存为高质量的任何图像格式（JPEG，PNG），如何在Silverlight中使用c＃做到这一点。我看到了Fjcore代码，但我不明白它正在执行操作，请提供代码说明并评论其操作。

You can try Imagetools for Silverlight library in Codeplex . Here is an example on saving a canvas element to JPEG image :

//Convert UIElement to Image
ei = ImageExtensions.ToImage(myCanvas);

//Save the image
SaveFileDialog saveDlg = new SaveFileDialog();
saveDlg.Filter = "JPEG Files (*.jpeg)|*.jpeg";
saveDlg.DefaultExt = ".jpeg";
if ((bool)saveDlg.ShowDialog())
{
    using (Stream fs = saveDlg.OpenFile())
    {
        ei.WriteToStream(fs);
    }
}

Further information on how to use it can be found in the link above, and as I see it, looked very simple.
