How can I determine whether this PDF has errors? Is there a corresponding API? Thank you very much
How can I determine whether this PDF has errors? Is there a corresponding API?
Some errors are already detected when the PDF is opened - like in this case, where the central cross reference (xref) table is broken. MuPDF will then try to repair things by generating a new xref table from walking through he full file. This is usually accompanied by error and warning messages. Some of those are written to the console, the full message are also stored in the area pymupdf.TOOLS.mupdf_warnings() - as shown.
Whether a repair had been tried can be determined by looking at doc.is_repaired.
Not all errors can be detected at open time though. Some will only be exhibited when certain information is extracted like text or during rendering the pages' visual appearance.
