I've done so in a few occasion, and it worked out fine.
Here's an example with IDL, LaTeX and unix commands, which
I put together with some help from this newsgroup a while ago:
IDL commands to generate a figure with b and t as text markers:
N=1000
x=findgen(N)/(N-1)*10-5
mu=0.
sigma=1.
y=total(exp(-(x-mu)^2/(2*sigma^2)),/cumulative)*(x[1]-x[0])
set_plot,'PS'
device,filename='fig1.eps',/encapsulated,xsize=12.,ysize=8.
!p.font=0
plot,x,y,yrange=[0.,3.],thick=4,/xstyle,xrange=[-5,5],xtitle ='x',ytitle='y'
oplot,!X.crange,sqrt(2*!Pi)*sigma*[1,1],linestyle=2
xyouts,0.,1.,'t',/data
xyouts,-3,2.65,'b'
device,/close
set_plot,'X'
;END IDL
LaTeX file:
\documentclass{article}
\usepackage{geometry}
\usepackage{graphicx}
\usepackage{psfrag}
\pagestyle{empty}
\geometry{paperwidth=12.1cm,paperheight=8.1cm,margin=0pt}
\begin{document}
\psfrag{t}[l][][1.35]{$\displaystyle y=\int_{-\infty}^x
e^{-\left(\frac{t-\mu}{\sqrt{2}\sigma}\right)^2}\,\mathrm{d} t$}
\psfrag{x}[c][][1.75]{$x$}
\psfrag{y}[c][][1.75]{$y$}
\psfrag{b}[c][][1.35]{$\displaystyle y=\sqrt{2\pi}\sigma$}
\includegraphics[width=11.9cm,height=7.9cm]{fig1.eps}
\end{document}
%end latex
Linux command to TEX and transform into eps:
latex doc.tex
dvips -o fignew.ps doc.dvi
ps2epsi fignew.ps fignew.epsi
perl -ne 'print unless /^%%BeginPreview/../^%%EndPreview/' < fignew.epsi > fignew.eps
rm fignew.epsi
Now you should have an eps file with equations rather than "t" and "b" labels...
Hope this helps,
