General ⇒ PDF Document Properties

[justastudent]

Hello,

Including a figure in EPS format generated by Gnuplot and creating a PDF using LaTeX -> DVI -> PS -> PDF, the document properties (title, subject, creator etc.) of the generated PDF are taken from the last EPS figure included.

If I try another figure in EPS format not created by Gnuplot (Adobe or so), the document properties are correct.

Code: Select all

\documentclass{article}
\usepackage{graphicx} 
\begin{document}
  \begin{figure}[h]
    \centering
    \includegraphics{figure.eps}               
    \caption{Test EPS}
    \label{fig:test}
  \end{figure}
\end{document}

I tried \hypersetup, but still getting the same output.

With current versions of the common TeX distributions it should be possible to compile with PDFLaTeX while including EPS figures. At least with TeX Live 2011 it works. EPS figures are converted to PDF on the fly.


Best regards and welcome to the board

Well, it is possible to use pdflatex on .eps, but then psfrag won't work.

That is something you should have mentioned right at the beginning. Then I wouldn't have proposed this approach.

There is a much smarter way to get nice plots by the pgfplots package. It uses Gnuplot as back-end. Perhaps you can upload a data set and a sample plot to the forum server so that we can see how your plots should look like. We then would be able to reproduce it with the package and do other additions for which you used psfrag.

Next time, I would do it that way as you suggested or use other ways like create a tex file with gnuplot. But the fundamental question remains, why the ps2pdf conversion creates a pdf with the document properties changed (i.e. inherit the properties of the last gnuplot-created .eps image in the file) instead of taking the properties of the original .ps file?

Could you check the properties of the pdf created using the following code and eps file attached ? In document properties, you get Title: comp.eps (original name of the eps before renamed to figure.eps), Subject: gnuplot plot etc. instead of the expected Title: filename.pdf etc.

Code: Select all

\documentclass{article}
\usepackage{graphicx}
\usepackage{psfrag}
\begin{document}

\begin{figure}[h]
  \centering
      \psfrag{Percentage}{\scriptsize Graphs (\%) }
   \psfrag{Rho}[bl][bl]{\scriptsize $\rho$ }
\includegraphics{figure.eps}               
   \caption{Test EPS}
  \label{fig:test}
\end{figure}
\end{document}

This is a known problem with dvips' interpretation of the pdfmark set by Gnuplot, i.e. it's a bug on the LaTeX side. The only way I've been able to overcome it is to edit the EPS file directly in a text editor before including it in a LaTeX document. Specifically, look in the EPS file for a section that looks like this:

Code: Select all

SDict begin [
  /Title (something.tex)
  /Subject (gnuplot plot)
  /Creator (gnuplot 4.4 patchlevel 3)
  /Author (someone)
  /Producer (gnuplot)
  /Keywords ()
  /DOCINFO pdfmark
end

Comment out the /Title, /Subject, /Creator, /Author, /Producer, and /Keywords commands with a percent sign:

Code: Select all

SDict begin [
%  /Title (something.tex)
%  /Subject (gnuplot plot)
%  /Creator (gnuplot 4.4 patchlevel 3)
%  /Author (someone)
%  /Producer (gnuplot)
%  /Keywords ()
  /DOCINFO pdfmark
end

If you then run LaTeX -> dvips -> ps2pdf the PDF should have the correct meta data. It's a little inconvenient to remember to do this all the time for Gnuplot-generated files, but I'm used to it by now.
