xRefTable failed: pdfcpu: can't find last xref section about pdfcpu HOT 10 CLOSED

under512byte.pdf

Ah, I can upload it by drag'n'drop. Here it is.

There are a lot of things that can go wrong just during the initial process of detecting xref sections, xref streams and such, because PDFWriters mess up. That's why.

This is fixed with the latest commit!

Hell... I figured it out. The PDF needs to have a minimum size of 512 byte to get recognized by pdfcpu!

Can you do me a favor and share this file for analysis?
Thank you!

Hm? I did. Just copy the code into a file and save it as PDF.

However, the error would have to be renamed. The problem was not my PDF, but that the minimum size in pdfcpu must be 512 bytes - as far as I know, this does not have to be the case.

Nope that's not really how it works.
Many times the issue is how the file was saved, specific offsets and such,

Interesting view. This is the first time I've heard that someone prefers a binary file

I've been working with handcrafted PDFs for many years and never ran into such issues. But okay...

Thank you! I'll test it later. The error totally confused me because I couldn't find anywhere that the PDF file had to have at least 512 bytes and all other interpreters could handle it :-)

Well, thx for discovering this!
