---------------------------------
Summary: FOP PDF Images - Some PDFs produce Error in Acrobat Reader
Key: FOP-3136
URL: https://issues.apache.org/jira/browse/FOP-3136
Project: FOP
Issue Type: Bug
Reporter: Rafael Witak
Attachments: resultA.pdf, resultB.pdf, resultC.pdf, sourceA.pdf,
sourceB.pdf, sourceC.pdf
Including some PDFs as external-document results in a PDF that produces an
error in Acrobat Reader (but not in Chrome!). The error message reads "{*}There
was an error processing a page. There was a problem reading this document{*}
{*}(18).{*}" and after Ctrl-click on OK "{*}Expected a name object{*}{*}.{*}"
is added. No page is visible.
The issue can be traced back to FOP PDF Images and exists in all its versions
>=2.6. Versions 2.5 and lower produce results that work.
While the original PDFs do have some issues when checked with a tool like
[pdfcpu|https://github.com/pdfcpu/pdfcpu/releases/tag/v0.4.0], others with
similar issues don't produce the same error. The originals _can_ be opened by
Adobe Reader without a problem.
No ERROR or WARNING is logged. Searching on Google / Jira / the mailing list
did not produce comparable problems.
Due to the fact that I get the copyrighted PDFs as-is by the customer, I don't
have much freedom in either changing them to work around the problems, or
provide too many examples.
