Google does crawl PDF docs.
That being said, I would not worry too much about the duplicate content side of things as Google will just not index the PDF.
If you have an html page with content on it.. get that indexed first and then if you put a PDF on the site for download, you can and it will not be indexed because it MAY be viewed as duplicate but you will not get penalized for it.
If you are really concerned about it, then just do a no follow on the PDF.
Google can not read text in images or see if images are duplicate. The only wat they can tell is if you name the images the same name as each other in the ALT text.
Enjoy the little things, for one day you may look back and realize
they were the big things.
