Using psfrag with pdflatex
======================================================================

German (not up to date) version: README.de

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.

The basic idea around the problem is the following:

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 the included fragmaster.pl perl
script.

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:

    * <graphics>_fm.eps: the EPS file itself,
    * <graphics>_fm: a fragmaster control file.

From these files the psfragged graphics will be created:

    * <graphics>.eps,
    * <graphics>.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 (a little like "make" would do it).

In your LaTeX document you can include the produced graphics using

\includegraphics{<graphics>}


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

======================================================================
Example
======================================================================
The following example files are included:

    * parabel_fm.gp
      gnuplot file to create the following EPS graphics,
    * parabel_fm.eps
      raw EPS without psfrag replacements,
    * parabel_fm
      fragmaster file with the psfrag commands,
    * parabel.eps
      the produced EPS graphics,
    * parabel.pdf
      the produced PDF graphics,
    * document.tex
      LaTeX example including the graphics,
    * document.pdf
      example PDF,
    * document.ps
      example PS,
    * parabel_fm.pdf
      PDF version of the raw EPS graphics (only necessary for the
      example!).


======================================================================
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 warmly to you...

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

Bugs and more info
======================================================================

For further details, please see "fragmaster -m" in UNIX systems (needs
perldoc) or fragmaster man page if available. If directly downloaded
from CTAN or used the one included in a win32 TeX distribution, please
see fragmaster.pdf if available. Both are derived from fragmaster.pl
pod section, located at the end of the script. Look there if the other
formats are not available.

Send bug reports to:

  Agustin Martin <agustin martin hispalinux es> (fill in: dot at dot)

In particular, the use of directory control files is a recent addition
that still needs extensive checking.

Your feedback is appreciated.

Enjoy.
