C#: How do I convert a multi-page TIFF via MemoryStream into one long image?

So I have been able to take a multi-page TIFF file and convert it to a single jpeg image but it flattens the TIFF. By flatten it, I mean it only returns the first page. The goal is to retrieve the TIFF (via memory stream), open each page of the TIFF and append it to a new jpeg (or any web image). Thus creating one long image to view on the web without the aid of a plugin. I do have the MODI.dll installed but I am not sure how to use it in this instance but it is an option.

How to take screenshot of div from a webpage using C# and ASP.NET?

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?
