Thanks a lot. For that file extract the barcode, but for this pdf file https://drive.google.com/file/d/0B8GFWmLzuj1QbE1HVENYd3VRems/view?usp=docslist_api why don't extract barcode, only four bars (two white and two black bar)?
That is because this file uses a different strategy to display the barcode. It just repeats the two images you mentioned.
