PDF from latex

[Damien Cassou-3]

Hi,

I do not understand why extractor does not get the author and title
from PDF files which are generated by pdflatex.

Here is a very simple LaTeX file:

$ cat main.tex
\documentclass{article}

\title{The title}
\author{The author}

\begin{document}
\maketitle
the article
\end{document}

Then I compile it:

$ pdflatex main
$ pdflatex main
$ extract main.pdf
software - This is pdfeTeX using libpoppler, Version
3.141592-1.30.5-2.2 (Web2C 7.5.5) kpathsea version 3.5.5
creation date - 20070903172617+02'00'
creator - TeX
producer - pdfeTeX-1.30.5
format - PDF 1,0
mimetype - application/pdf

There is no notion of author or title here.


Bye

Simple -- your \author and \title don't really show up in the PDF metadata.  
You need to do this (after the last exsting usepackage):

\usepackage{hyperref}
\hypersetup{backref,
  pdftitle=A title,
  pdfauthor=Christian Grothoff,
  pdfkeywords=foo bar,
  pdfsubject=Computer Science,
  colorlinks=true}


Best regards,

Christian

Thank you very much. However, this does not help me much because I do
not have the control over the original LaTeX files. They are already
produced and I don't have the sources. I just find it strange that
hyperref does not use the LaTeX metadate per default.

Thank you
