title: How to read QR Code from pdf files using asp.net
body: <p>I am working on an asp.net core 2.1 application where user will upload a PDF document with QR Code which is on each page of pdf. I need to read that QR code. Which library do I need to use for this. I tried to use itextSharp but it is not reading QR from pdf. If PDF has image with QR code then itextsharp reads the QR Code.</p>
  
  <p>Please suggest.</p>
