A very useful trick for using psfrag with pdflatex came across here. I am just blindly copy pasting this (fearing that the original link go missing for whatever reason. Well it is not all that hard to remember, but someone may find it useful and save some internet searching time) from the source link [1]

Using psfrag with pdflatex

German version

psfrag is a LaTeX package which allows to replace text elements in included EPS graphics by arbitrary LaTeX output. E.g. you can make fonts in your graphics match your document fonts or even include mathematical formulae in your graphics. For example:

\psfrag{x}{$x$}\psfrag{y}{$y = x^2$}\includegraphics{diagram}

When using latex (not pdflatex) the file diagram.eps will be included. The extension is appended automatically. While doing this, every occurrence of “x” in the diagram is replaced by “x” using math font and every “y” is replaced by the LaTeX formula “y = x^2”. Partial strings are not replaced, only completely matching strings.

Because psfrag uses Postscript for making the replacements, in principle you can’t use psfrag with pdflatex which doesn’t have any interfaces to postscript.

A possible way around the problem is the following:

The basic idea is to produce a new EPS from your original EPS which already contains all those psfrag replacements. This new EPS graphic actually can be converted to PDF including all replacements. The resulting “encapsulated” PDF then can be used with pdflatex.

To make such an EPS which already contains the replacements, it is necessary to create a separate LaTeX document for every EPS file you use. To simplify that task, I wrote a perl script which can be downloaded right here:

fragmaster.pl

This script needs: perl, latex, dvips and the common EPS to PDF converter script epstopdf.

To use the script you have to create two files per graphic:

• _fm.eps: the EPS file itself,
• _fm: a fragmaster control file.

From these files the psfragged graphics will be created:

• .eps,
• .pdf

The control file is basically a LaTeX file (with optionally special comments) and can look like this:

% Just an ordinary comment%% A special comment:% fmopt: width=6cm%% Another special comment:% head:% \usepackage{amsmath}% end head

% psfrag commands:\psfrag{x}{$x$}\psfrag{y}{$y = x^2$}

The special comment fmopt: will be evaluated such that the following text will by passed as optional argument to \includegraphics. This way you can e.g. adjust the relation between graphics size and font size using something like width=6cm.

The special comment construct "head:"/"end head" causes the lines in between to be included in the preamble of the LaTeX temporary document after having the leading comment characters “%” stripped off. This way, you can include LaTeX packages.

fragmaster.pl will scan the current directory for files which end in _fm and their _fm.eps counterparts. Looking at the modification dates, the script checks if the output files have to be remade and does so if necessary.

In your LaTeX document you can include the produced graphics using

\includegraphics{}

conveniently omitting the file extension. latex will choose the EPS, pdflatex will choose the PDF.

Problems and solutions

In case the EPS will be produced as landscape graphics, i.e. gv shows “Landscape” instead of “Portrait” in the menu bar, and the graphic will end up turned around 90° in your document, then it is likely that your original EPS is wider than it is tall. In this case some (more recent) versions of dvips make the “smart” assumption that your graphic is landscape, even though the graphic’s proportions don’t tell anything about the orientation of its contents… Anyway, you can make dvips behave nicer by specifying the following line in /usr/share/texmf/dvips/config/config.pdf (or a local equivalent inside /usr/local/share/texmf):

@ custom 0pt 0pt

In the likely case that you’re wondering why, I’d recommend the dvipsk sources (to be found in the tetex bundle) warmly to you…

Have fun with the script! Feedback is very much appreciated.
