title: Check if image is on pdf using iTextsharp
body: <p>I am working on trying to make a little console application that can tell the difference between a blank page, and a page with only one image on it and no text. For the blank page I'm using iTextsharp's SimpleTextExtractionStrategy() and that works great for the blank pages. The problem is the pages with only the image on them are considered to be blank by this method as well. Is there a way to know if a pdf has an image on it similar to the way I am checking for text on the pages?</p>
