GetThumbanails() method is not working!

Hi,

We are getting Exception "Object reference not set to an instance of an object." for GetThumbnails method.
Please check the code..

System.Drawing.Image image = slide.GetThumbnail(new Size(500, 375));

Please Help!

Thanks,
Lakshmi Bhavani.

Dear Lakshmi,

The code is ok; can you please provide us source presentation or stack trace of exception to look into this further?
