Hi,
Here's a description I have found one day. I think gives you
everything you wanted to do.

The following is a document on how to import xfig figures in latex along
with a few tips to make your life easier. I wrote this quite a while
back but it still applies.
Salut,
Eric
HOW TO IMPORT XFIG FIGURES IN YOUR LATEX FILES:
--------------------------------------------------------------
Getting Started
---------------
When you call xfig use the following command line:
xfig -specialtext -latexfonts -startlatexFont default
If you want ALL of your figures to be started with special text and
latex fonts, you can set the following resources in your .Xresources
or whatever resource file you use:
Fig.latexfonts: true
Fig.specialtext: true
There are several formats to which xfig can generate output and
latex can read. I will only cover three cases:
(A) Export Fig format directly into latex form
(B) Export Fig in encapsulated postscript and import the
postscript in latex.
(C) Save the figure partly in postscript and partly in latex
form and superimpose them in your document.
All three methods have their advantages and are equally simple
to handle. In method (A) the advantage is that all your work
is in tex form and that your .dvi files will hold all the necessary
information. In (B) you have all the power and fonts of postscript
at your disposal. In (C) you get the drawing power of postscript
and the typesetting of latex for your strings.
---
In your latex preamble (the part that preceeds your
\begin{document} statement) place the following lines:
\input{psfig}
So your preamble could look like:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% LaTeX Preamble %%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentstyle[12pt,bezier,amstex]{article} % include bezier curves
\renewcommand\baselinestretch{1.0} % single space
\pagestyle{empty} % no headers and page numbers
\oddsidemargin -10 true pt % Left margin on odd-numbered pages.
\evensidemargin 10 true pt % Left margin on even-numbered pages.
\marginparwidth 0.75 true in % Width of marginal notes.
\oddsidemargin 0 true in % Note that \oddsidemargin=\evensidemargin
\evensidemargin 0 true in
\topmargin -0.75 true in % Nominal distance from top of page to top of
\textheight 9.5 true in % Height of text (including footnotes and
figures)
\textwidth 6.375 true in % Width of text line.
\parindent=0pt % Do not indent paragraphs
\parskip=0.15 true in
\input{psfig} % Capability to place postscript drawings

TYPE A - Exporting directly to latex form
-----------------------------------------
In terms of drawing capabilities this is the weakest form you can use.
Lines in latex can only be drawn at multiples of 30 and 45 degrees.
And lines with arrows can only be drawn at multiples of 45 degrees.
Several features such as ellipses, splines, etc. are not supported
(xfig does not take advantage of available LaTeX macro packages
such as bezier). When drawing lines for type A drawings make
sure you restrict yourself to the proper angle geometry in xfig.
Otherwise when you export your figures to latex format, xfig
will approximate your lines to the nearest angle available in latex.
Usually this has unpleasant results.
In this mode, you can type any LaTeX string on your
figure. Once imported to LaTeX, the string will be interpreted
properly. For example:
$\int_0^9 f(x) dx$
would result in a integration from 0 to 9 of the function f(x).
To create your LaTeX file just choose the export option off the
xfig main menu. And then select LaTeX picture as the language
to export. This will create a file with a .latex extension which
you can then call directly into your latex document. For example
this code would import the file yourfile.latex directly into latex
format:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Figure 1 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{figure}[htbp]
\begin{center}
\input{yourfile.latex}
\caption{The caption on your figure}
\label{figure:yourreferencename}
\end{center}
\end{figure}
TYPE B - Exporting to Encapsulated postscript
---------------------------------------------
There are no limitations in drawing figures of this type. Except that
one cannot use latex command strings in this format. However all
of the many fonts of postscript are available when this format
is selected. Once you are done drawing your figure simply choose the
export menu off of the xfig main menu and select encapsulated postscript
as your output language. This will create a .eps file which you can then
include into you latex ducument in the following way:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Figure 2 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{figure}[htbp]
\begin{center}
\ \psfig{file=yourfile.eps}
\end{center}
\caption{Your caption}
\label{figure:yourreference}
\end{figure}
TYPE C - Postscript/Latex format
--------------------------------
You can draw any lines or curves when using this format.
In this type of export, latex strings are permitted
you also have the postscript fonts available to you. Therefore
you can type in strings such as
$\int_0^9 f(x) dx$
and they will be processed by latex. You will need to export
your file twice when using this format: once to the
combined ps/latex (ps part) language and once to the combined
ps/latex (latex part) language. The first will create a .pstex
file and the second will create a .pstex_t file. The .pstex_t
file automatically calls the .pstex file and you do not need
to include it explicitely in your tex file (users of the previous
version please take note of this.) To include your figure
just use something similar to this:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Figure 3 of Lecture %%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{figure}[htbp]
\begin{center}
\input{yourfigure.pstex_t}
\caption{Your figure}
\label{figure:example}
\end{center}
\end{figure}
N.B. You might want to edit the .pstex_t files created by xfig.
When it refers to the other file (.pstex) it automatically
gives the path specification to the .pstex file. This
can be an inconvenience if you move your files to another directory
because your latex processing will fail. I personally prefer to
remove the full path specification and only keep the filename.
SOME OTHER NOTES
----------------
xfig
----
You can import encapsulated postcript files into your latex files.
This is useful if you want to doodle on top of outputs from other
programs. For example you could include a MATLAB drawing and identify
points of interest with strings, lines, circles, etc. Starting from
version 2.1.7 of xfig there is a hook to ghostscript which permits
you to view the postscript in your drawing. A neat feature.
Use ps2epsi in ghostscript to encapsulate your postscript if you only
have .ps files.

Some more notes from Stephen Eglen <[EMAIL PROTECTED]>
* changing the size of pictures in pstex_t
If you just include the picture using
\input{file.psttext_t}
you have no way of specifying the size of the picture. There are two
solutions to this.
1. Draw it the right size in xfig to start with. Or, when you are
exporting the figure, change the magnification of the picture by
using the magnification box in the export window. Either way you
have to go back into xfig if you dont like the size of the image in
your latex document.
2. Get latex to change the size of the picture, using either \scalebox
or \resizebox. These are general functions for scaling text or
pictures from the graphics package:
\scalebox{factor}{object}
Will scale the object by any factor.
Factor is just a number (<1 = reduction; >1 = enlargement)
Object is normally some text or graphics
eg: \scalebox{2}{ \input{file.pstex_t} }
will scale the picture by 2, dependent on driver (.ps works, but xdvi
wont). Scaling bitmap fonts may produce ugly results, so try and
avoid them!
\resizebox{width}{ht} {stuff}
will resize "stuff" to be of size width x ht. Using "!" as an argument
retains the aspect ratio of the box.
eg \resizebox{5cm}{!}{fat cat} will make "fat cat" appear 5 cm wide,
and suitably high.
