Looking for C++ library to extract image in PDF together with location

I am developing applications using C++ at university.

As a requirement of the application, it is necessary to extract data from a PDF file together with location (x position and y position on a page) in which texts and images are embedded.

Is there a useful C++ library? Or should I analyze the data structure of the PDF file and extract the data?
