<H1>Introduction
</H1>

<B>Xfig</B> is an interactive drawing tool which runs under 
<A HREF="http://www.opengroup.org/tech/desktop/x" target=_new>X Window System</A>
Version 11 Release 4 (X11R4) or later, on most UNIX-compatible
platforms, and e.g. under Darwin on the MacIntosh and any X server under Microsoft Windows. 
See the <a href="installation.html">installation</a> section for details.
It is <A HREF="authors.html#xfig">freeware</A>, and available
via <A HREF="installation.html">anonymous ftp</A>. 
<P>
In <B>xfig</B>, figures may be drawn using objects such as 
<A HREF="drawing.html#circle">circles</A>,
<A HREF="drawing.html#box">boxes</A>, <A HREF="drawing.html#polyline">lines</A>,
<A HREF="drawing.html#spline">spline curves</A>, <A HREF="drawing.html#text">text</A>,
etc. It is also possible to <A HREF="drawing.html#picture">import
images</A> in formats such as GIF, JPEG, EPSF (PostScript), etc. Those objects
can be <A HREF="drawing.html">created</A>, <A HREF="editing.html#delete">deleted</A>,
<A HREF="editing.html#move">moved</A> or <A HREF="editing.html">modified</A>.
<A HREF="attributes.html">Attributes such as colors or line styles</A>
can be selected in various ways.
For text, <A HREF="attributes.html#font-panel">
35 fonts</A> are available. Text can also include <A HREF="drawing.html#compose-char">Latin-1
characters</A> such as &quot;<IMG SRC="images/a-umlaut.png" ALT="a umlaut" >&quot; or
&quot;<IMG SRC="images/c-cedilla.png" ALT="c cedilla" align=top>&quot;.

<P>And here are some example figures extracted from the <B>xfig</B> distribution.
Click on them to see a larger version.

</BLOCKQUOTE>

<P>
<B>Xfig</B> saves figures in its native
<I><A HREF="fig-format.html">Fig format</A></I>,
but they may be <A HREF="printing.html#export">converted
into various formats</A> such as PostScript, GIF, JPEG, HP-GL, etc. <B>xfig</B>
has facility to <A HREF="printing.html#print">print figures to a PostScript
printer</A>, too.

<P>There are <A HREF="installation.html#related-apps">some applications</A>
which can produce output in the <I>Fig format</I>.
For example, <B>xfig</B> doesn't have a facility to create graphs,
but tools such as <B><A HREF="installation.html#gnuplot">gnuplot</A></B>
or <B><A HREF="installation.html#xgraph">xgraph</A></B> can create graphs
and export them in <I>Fig format</I>. Even if your favorite application
can't generate output for <B>xfig</B>, tools such as 
<B><A HREF="installation.html#pstoedit">pstoedit</A></B>
or <B><A HREF="installation.html#hp2xx">hp2xx</A></B> may allow you to
read and edit those figures with <B>xfig</B>. If you want to import images
into the figure but you don't need to edit the image itself
(like <A HREF="screen_image_map.html">this example</A>),
it is also possible to <A HREF="drawing.html#picture">import
images</A> in formats such as GIF, JPEG, EPSF (PostScript), etc.

<P>Most operation are performed using the mouse, but some operations may
also be performed using <A HREF="accelerators.html">keyboard accelerators</A>
(shortcuts). Use of a three-button mouse is recommended, but it is also
possible to use a two-button mouse (if you have a two-button mouse and
your X server doesn't emulate a three-button mouse, press the Meta (or Alt) key
and right mouse button together to simulate mouse button 2). Normally, mouse
buttons 1 to 3 are assigned to the left, middle, and right buttons respectively.

<P><B>xfig 3.2.X</B> and <B>fig2dev 3.2.X</B> include code for internationalization,
it allows use of local characters (e.g., Japanese) in <B>xfig</B>.
It uses standard internationalization (I18N) mechanism of X11R5,
and known to work for Japanese and Korean at this time.
See <a href="i18n.html">Internationalization</a> about this.
