Solution 1

There are a tonne of examples on how to do each step on Google Search. Here is a solution based on a Google Search[^] that I used...

The first thing to do is either extract the image from the PDF or to convert the PDF to an image.

1b. Simple and Free PDF to Image Conversion[^]

The next thing to do is to extract the barcode. Here is a code project article that does just that.
