I have the following problem. I would like to open PDFs like this on a certain cited page:
https://slub.qucosa.de/api/qucosa%3A89546/attachment/ATT-0/

As you can see, the page enumeration and page number are different.

For jumping to the right page, I would need the page enumeration. Is there any way, to access the enumeration-information? So that I know, that page 15 is on page 39?

Thanks in advance,

Erik
