@JanSlabon

We found this ticket by searching the web. We are getting similar error (shown below) in our production environment. We are purchased and using FPDI_PDF-Parser-2.0.3.

• Since this issue is already closed, can you reopen this please.
• And we will be able share the PDF file which is causing the issue via a private email. Please let me know how we could share a production/client pdf file with you directly instead of this public portal.

If you need any other details, please let us know. Thanks and your help is very much appreciated.

Here is the error:

Please send the PDF in question to [email protected], thanks!

Appreciate your quick response. I believe we may have found the issue.

• The original file possibly is an paper invoice scanned or taken as a picture in high resolution and saved as PDF. The page size in this document is set to 23.61 x 32.47 in
• It is still a valid PDF document.
• I just reprinted using Acrobat reader into 8.50 x 11.00 in standard letter size and then used it in our process. And that worked.
• Just for your reference, I'm adding a screen shot of the PDF properties page.
  

What we are trying to do in our process is to combine images and other attachments into a single PDF document. I believe the FPDI-PDF_Parser by default is set to use 8.50 x 11.00 in and not able to handle the large page size file.

Let me know what I'm saying here make sense. If you still need the pdf file, let me know and I'll send it to you.

Your "solution" has nothing to do with the main problem and FPDI does not set any default page size (but FPDF or TCPSD) nor does not support large files. The initial PDF document simply have an invalid/faulty structure in it. The viewer you are using seems to ignore that problem which allowed you to simply reprint it. Maybe a complete resave would also fix this.

The problem IS the in-file and without analyzing it, it is impossible to see how and if we can fix this.

Ok, I just sent you the file in question to [email protected] email address.

[JanSlabon]

Thanks!

The problem with this file is following:
The file includes only a single cross reference but internally it points to a previous one at byte offset 0:

trailer
<< /Prev 0 /Root 5 0 R /Size 6 >>

FPDI finds an object after jumping to this offset but it is simply not a valid cross-reference.

I just fixed this with #58. An official release will follow in the next days or weeks.

Thank you.
