Your best bet is to get a PDF library that can extract images from the pages. We use Aspose.PDF and Aspose.PDF.Kit, which are both excellent products.

This page shows a code example of how to extract an image from a PDF document:

They also have a Barcode library, and one of the things it can do is read barcodes from multi-page tiff images. You could convert the pages of your PDF to TIFF and then use the barcode library to read the barcodes:
