Subject: [pdftex] errors in pdf files?
Message-ID: <4B8BCD24.1040006@elzevir.fr>

Hi,

As part of a routine check, I noticed that pdfinfo complains about the two
following files on CTAN, apparently produced by pdftex:

1. http://mirror.ctan.org/macros/latex/contrib/dvdcoll/doc/dcexample.pdf
Error: Reference in Fields array to an invalid or non existant object
(repeated many times)

2. http://mirror.ctan.org/macros/latex/contrib/etextools/etextools.pdf
Error: Annotation destination array is too short

xpdf issues the same errors, but manages to read the file anyway. I'm not sure
whether these errors are real or an artefact of pdfinfo, and what should be done
about it. (Just to be sure, I recompiled dcexample.tex with a more recent pdfTeX
(1.40.10) but it didn't change anything.)

Since I don't understand the errors, I don't know whether they are actually
related to pdfTeX, so if my message is misplaced on this list, I apologize for
the noise and hope you'll be kind enough to give me some pointers about these
errors.


Thanks,
Manuel.

I can't reproduce this. pdfinfo is 3.02.
Are you using poppler?

AR9 preflighting finds some errors, but these are harmless.

AR9 finds no errors.

Ok.

Ok.

By the way, how do you look for errors with AR? Do you just open the file and
look at stderr, or is there something special to do in order to check the file?

Thanks,
Manuel.

Hello,

A bad interaction between packages tabularx and pdfnotiz.
The latter package provides \pdfnote that uses \pdfannot
and stores the object numbers via \pdflastannot in a macro.
However tabularx puts a tabular line several times in a box,
the annotation of the rejected boxes are gone away, but
the object numbers are still in that macro.
  Possible solution: the numbers cannot stored in a macro directly,
but must go to an auxiliary file (e.g. .aux file) first. Either
the box is kept, then the \pdfannot and \write, or both are
thrown away.

FitH needs a number as parameter (vertical position).
The error is in the source file etextools.dtx:

  % \AddBookMark{attr{/F 2}goto page 1{/FitH}{etextools}}

can be fixed by

  % \AddBookMark{attr{/F 2}goto page 1{/FitH 1000}{etextools}}

Or the value can be calculated using \hypercalcbp, see hyperref's manual.

Alternatives are macro \pdfbookmark of package `hyperref'
or the commands of package `bookmark'.

The same error occurs in ltxdocit.cls:
  ltxdockit.cls:  pdfview=FitH,
  ltxdockit.cls:  pdfstartview=FitH}
