Checking the number of images in a PDF document


How can I check if a PDF does NOT contain images?
If I use ExtractImage() and no images are present, then the call to HasNextImage() returns an error:

"Object reference not set to an instance of an object"

Thanks for a quick reply.

Find whether PDF file contains images or text only

I hope this helps.
