Yes, I think it is. The point is that latex need to search and replace
your text labels, but it cannot find them if they are encoded as anything
different than plain text. Using device fonts should ensure that. I am
not sure exactly how to do the same using true type font...

Well, this is not really necessary, don't bother. Since dvips produces a
ps file, if you really want an eps you'll have to convert the ps to eps
in whatever manner you like (on my machine I just happen to have
ps2epsi available, so that's what I used). The reason for that is to
have a separate, final eps file with the figure *and* the latex
embellishments, which could afterwards be directly included into another
(either latex or non-latex) document without need for additional processing.
You're right about removing the preview, just save some disk space.

Many thanks! That is great news, my search of this group had turned up
only mention of LaTeX package psfrag in 1997...

I'll try this at work in the morning, for use. Is the setting of font
to 0 one of the critical tricks?

Excellent! So the below could be put into a separate .tex file and
\input into the main document as I am used to doing under Matlab with
the laprint program.

Ah, this part is new to me. Any idea what this is repairing, since
you've already specified emcapsulated PS in your IDL program. (I
understand the perl part after that to remove the preview TIFF image.)

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,
Paolo Grigis

No worries, I'm very very happy to get the help I did! Worked
beautifully (I temporarily installed a Windows version of IDL under
linux at home using wine, and tested, happy to go to bed knowing it
will work at the office).

Ah, yes, understood. In that case of course the fonts are now fixed,
no longer modifiable by the document, as I understand it. But I think
you are incorrect in one aspect: IDL produced an EPS file when you
gave it the /encapsulated modifier for the device. Here the top lines
from my file:
%!PS-Adobe-3.0 EPSF-3.0
%%BoundingBox: 0 0 340 226
%%Title: Graphics produced by IDL
%%For: gernot@hase, C:\RSI\IDL60
%%Creator: IDL Version 6.0, Microsoft Windows (Win32 x86 m32)
...
Many thanks once again,
Gernot

| array subscript conversion [message #55037 is a reply to message #54938] |

Hi guys,
according to the manual, array subscripts are converted to long (or long64
on 64 bit systems) before use if necessary, so an explicit conversion
should not affect the result.
IDL> print, !version
{ x86 linux unix linux 6.3 Mar 23 2006 32 64}
IDL>
IDL> a=lindgen(10)
IDL> print, a[[long(-1ull)]]
0
IDL> print, a[[-1ull]]
9
Is it a bug or I am missing something?
regards,
lajos
