Failed to read xref table: Unsupported field size #25

Closed rorycl closed 4 years ago

rorycl commented 4 years ago

Hi. Here is an issue with v1.0.10:

panic: Failed to initialize parser: Failed to read pdf: Failed to read xref table: Unsupported field size in cross-reference stream dictionary - only tested with /W [1 2 1]

@rorycl thank you for the bug report and example PDF. I will update gofpdi to support variable field widths within a cross-reference stream. I'm planning on creating some unit tests that check to make sure the code can import all of the example PDFs you've provided so far.

@phpdave11 thanks for your rapid response. Sorry not to contribute patches due to lack of time and knowledge about PDF xrefs.

Feel free to use the PDFs I have provided as part of a test suite. However, I intend to delete them from my server in the next month or so if that is ok.

By the way I'm also getting some other problems with PDFs exported from Word: panic: Failed to get page resources: Page 5 does not exist!!

and another from Google Docs: panic: Failed to initialize parser: Failed to read pdf: Failed to read xref table: Failed to read prev xref: Unsupported /DecodeParms - only tested with /Columns 4 /Predictor 12

but I've been unable to recreate these issues on non-proprietary documents.

Thanks for your great work.

Thanks! If you are willing to send me sample documents generated from Word and Google Docs that cause those panics, I can work on fixing those issues as well.

@phpdave11 Unfortunately I'm having problems creating versions of confidential documents that exhibit the same import problems.

My register of current problems (as against v1.0.10) is as follows; interesting "Microsoft" doesn't appear in any of them.

@rorycl this has been fixed in gofpdi v1.0.11. If you are able to submit PDFs that produce these errors, please open a new issue for each one and I can work on fixing the bugs:
