Extract Images from a PDF

I am looking for a way to do the following:

1. Determine if a PDF file contains nothing but images
2. If so, extract all of the images out into separate files. 

We have DynamicPDF Merger for .NET v3 (we use it in our Imaging application to do page rotations, flips, splits and deletes).  Is what I am looking to do something that can be done with v3?  Thanks! 

Hello,

It is not possible to determine whether the PDF contains any images or not using our product. It is also not possible to extract the image or any content from the existing PDF file. You can only read the data from the Form Fields and you can fill the form fields with data without any problem using our product.

Thanks,

OK, good to know.  Thanks!
