Convert PDF to Image in web application

Question

How can I convert a PDF into an image in web application?

I am following this link to convert; it is working fine in window applications but in web applications, on,

Clipboard.GetImage().Save(outimg, outPutImageFormat);

It's throwing this exception,

System.NullReferenceException: Object reference not set to an instance of an object.

How I can implement this in Web Application?

Did you try looking up the exception? Almost all cases of `NullReferenceException` are the same. Please see "[What is a NullReferenceException in .NET?](http://stackoverflow.com/questions/4660142/what-is-a-nullreferenceexception-in-net)" for some hints. — John Saunders, Oct 13 '13 at 02:31

How about using this :

LibPDF library converts converts PDF file to an image. Supported image formats are PNG and BMP, but you can easily add more.
