My solution to the problem is to use the package mfpic with the
option metapost. Below is a complete latex source file for a formula.

\documentclass[a4paper]{article}
\usepackage[metapost]{mfpic}
\opengraphsfile{myname}

\begin{document}

\begin{mfpic}[20]{0}{4}{0}{4}
%the numbers are arbitrary but reasonable in the present context.

\tlabel(0,0){ $\int_a^b=f(x) dx$ }

\end{mfpic}

\closegraphsfile
\end{document}

After the first run of the document a file myname.mp is created which
one has to transform via the terminal using the command

mpost myname

After the second run of the document the file myname.pdf contains the
formula. One can then open this file with Adobe Illustrator and save
it as an .eps file.
