title: Generating dynamic thumbnail of a PDF for ASP.NET
body: <p>I've used a tool from Aspose (<a href="http://www.aspose.com/categories/file-format-components/aspose.pdf.kit-for-.net-and-java/default.aspx" rel="noreferrer">Aspose.PDF.kit</a>) to generate a JPG thumbnail on the fly of a PDF for a .NET application.  This works great,  but what kind of other alternatives are there?  Codeproject.com has <a href="http://www.codeproject.com/KB/GDI-plus/pdfthumbnail.aspx" rel="noreferrer">this tutorial</a>, but it requires you to have the full version of Acrobat.  </p>
  
  <p>Is there an open source alternative that's geared for ASP.NET? </p>
