如何使用c#和ASP.NET从网页上截屏div ?

I would like to create dynamic images from html that I'm generating on website. I have code that generates a PSN Trophy Card, ab Xbox LIVE Gamer Card, a Steam Gamer Card, and an Xfire Gamer Card. Each card is put into its own div and built dynamically from server side code. Is there a way to capture a screenshot of a selected div on a webpage using C# and ASP.NET?I would like to create dynamic images from html
