How can you read and change the x / y coordinates of a PDF in an iframe, my iframe looks like this: <iframe id="pdf-interface" class="pdf-interface" src=path></iframe> where path is the local path to the PDF file.
All attempts I've tried until now failed with the error message: Uncaught DOMException: Blocked a frame with origin "http://127.0.0.1:8080" from accessing a cross-origin frame.
Is there any way to fix this or an alternative way of doing this?

Serve the pdf from your localhost so origins are the same – charlietfl May 21 '21 at 22:22

You can't access cross-origin iframes directly.
Read more about it on Quentin's answer https://stackoverflow.com/a/66139466/7942242

I'll look into it, shame that there is no way to at least read out the page number of a pdf, this makes an iframe for PDFs kind of useless in my opinion – Paul Müller May 21 '21 at 22:33
