[pdftex] The Jhove verifier

[Ramón Casares]

Hi Ross,

The Jhove that I was using is the one packaged for debian:
   jhove_1.6+dfsg-1_all.deb

You can find it in:
   https://packages.debian.org/wheezy/jhove

Now, after installing the package,
you can reproduce what I have done.

First, write a BORRAR.tex file:
    \pdfoutput=1
    \pdfcompresslevel=0
    \pdfobjcompresslevel=0
    \pdfmapline{ptmr8r Times-Roman <8r.enc}
    \font\tenrm=ptmr8r
    \tenrm
    Welcome to pdf\TeX!
    \bye

Secondly, run pdftex on BORRAR.tex:
    pdftex BORRAR.tex

And then run the Jhove verifier on BORRAR.pdf:
    papa at PCBox:/tmp/tex$ jhove -m PDF-hul BORRAR.pdf

      Format: PDF
      Status: Not well-formed
      SignatureMatches:
       PDF-hul
      ErrorMessage: Lexical error
       Offset: 1568
      MIMEtype: application/pdf

Offset 1568 is within the \PTEX.Fullbanner string.

Now, if you take BORRAR.pdf
and replace the parenthesis inside that string
with square brackets, that is,

from
    /PTEX.Fullbanner (This is pdfTeX, Version 3.1415926-2.4-1.40.13
    (TeX Live 2012/Debian) kpathsea version 6.1.0)
to
    /PTEX.Fullbanner (This is pdfTeX, Version 3.1415926-2.4-1.40.13
    [TeX Live 2012/Debian] kpathsea version 6.1.0)

and run the verifier again:
    papa at PCBox:/tmp/tex$ jhove -m PDF-hul BORRAR.pdf

Then you see that everything is OK.
