[文件：合并发票pdf.pdf]

I encountered this problem when processing PDF format files. PDF package refers to a compressed file that integrates multiple PDFs into one PDF. The specific details can be found in the link I posted. Pymupdf seems to be unable to correctly parse this file and can only obtain cover information. Using Adobe Reader, you can see that it contains many files. Is there any good solution for this situation

How to reproduce the bug

import pymupdf

doc = pymupdf.open(file_path) page = doc.load_page(0) text =page.get_text()

PyMuPDF version

1.24.11

Operating system

Windows

Python version

3.9

Please directly provide a problem PDF. I cannot read Chinese and can thus not understand anything of what I am seeing when I follow your link.

Thanks for providing the file. This is no bug: PyMuPDF (MuPDF) does not support PDF portfolios and there are no plans to do so either. You may want to discuss with the MuPDF team in this Discord channel.
