I have a CMS system written in ASP.NET which among other things allows users to upload documents, typically PDF, powerpoint, Word etc.
I am investigating how to implement a preview function so that once the document has been uploaded it would generate a thumbnail of the first page in the document.
Does someone have an idea what libraries, controls are available to achieve this?
I ended up using Adeptol AJAX DocumentViewer. Very easy to implement and works with over 300 formats.
