<h2><a name="faq-general">General Questions</a></h2>

<ol>
<li>
<h3><a name="get_xfig">Where can I get <b>xfig/TransFig</b>?</a></h3>

<b>xfig</b> and <b>TransFig</b> are <a href="authors.html#xfig">freeware</a>
and you can get them from several sites.
See <a href="installation.html#install-xfig">Installing <b>xfig</b></a> about this.
<hr>

<li>
<h3><a name="convert">Do I need to convert old <b>Fig</b> files to the new version?</a></h3>

No. Every version of <b>xfig</b> and <b>TransFig (fig2dev)</b> can read <b>Fig</b> files
of any older version.  When you load one into <b>xfig</b> it converts
it to the latest version.  When you save it again it is saved in
that version.

<hr>

<li>
<h3><a name="edit_eps">Can I edit PostScript files with <b>xfig</b>?</a></h3>

No, but you can &quot;paint&quot; over them with <b>Fig</b> objects to add annotation or other objects.
Or you can convert the PostScript file into the <b>Fig</b> format using
<a href="installation.html#pstoedit"><b>pstoedit</b></a>
and then edit the <b>Fig</b> file using <b>xfig</b> in the usual way.

<hr>

<li>
<h3><a name="depth">I can't seem to control the drawing order of objects</a></h3>
When you have two or more objects that overlap and the drawing order is
important, you must set the <a href="attributes.html#depth"><i>depth</i></a>
of each object to guarantee the drawing order.

<hr>

<li>
<h3><a name="splines">My splines are being changed somehow from version 3.1 of
 <b>xfig</b></a></h3>

<b>xfig</b> 3.2 uses a new type of spline
called an <a href="authors.html#xspline">X-Spline</a>.
X-splines allow the user to mix interpolation and approximation
points in the same curve. More precisely, it means that an X-spline curve
is neither an interpolated spline nor an approximated one, it is BOTH
(the behaviour of each point is controlled by one single parameter
called &quot;shape factor&quot;).
<p>
<b>Caveat:</b> Because spline models of previous versions (quadratic B-splines
and Bezier with hidden points) are no longer supported, curves that are
present in version 3.1 and older files are automatically converted to
X-splines. This translation is only an approximation process. It means
that the converted curves are not exactly the same as the original ones.
Though the translation usually provides almost identical curves, some
hand-fitting may be needed in some pathological cases.

<hr>

<li>
<h3><a name="install_pers">How can I install <b>xfig</b> in a personal 
directory?</a></h3>

There are several files that you need:
<p>
<dl>
<dt><tt>xfig</tt>, <tt>fig2dev</tt>
<dd>These files should be put in your command search path.

<dt><tt>CompKeyDB</tt>
<dd>Set the <tt>XFIGLIBDIR</tt> variable in the <tt>Imakefile</tt>
to the directory you want this file to go into, or specify the file
with resource &quot;<tt>Fig*keyFile: <i>your_lib_area</i>/CompKeyDB</tt>&quot;.

<h2><a name="faq-running">Problems when running <b>xfig</b> or
<b>TransFig (fig2dev)</b></a></h2>

<ol>

<li>
<h3><a name="Xaw3Dlink">When I pull up a menu, <b>xfig</b> crashes</a></h3>

<dl>
<dt>POSSIBLE CAUSE:
<dd>Your version of the 3D Athena Widget Set may be incompatible

<p>
<dt>SOLUTION:
<dd>If your vendor has installed the Xaw3D1.5E verison of the 3D Athena Widget set
but has called it Xaw3D, then it is incompatible with <b>xfig</b>'s menu widget.
Fix this by uncommenting the <b>#define XAW3D1_5E</b> line in the Imakefile (remove the "XCOMM")
and recompiling <b>xfig</b>.  Be sure to do:
<dl>
<dd>xmkmf
<dd>make clean
<dd>make install
</dl>
</dl>

<hr>

<li>
<h3><a name="icons">Icons in side and bottom panels appear then disappear</a></h3>

<dl>
<dt>POSSIBLE CAUSE:
<dd>On Linux (2.0.29 at least), the libNextaw version of the Athena Widget
set (libXaw) seem to cause this problem.

<p>
<dt>SOLUTION:
<dd>Relink with vanilla libXaw or libXaw3d.
</dl>

<hr>

<li>
<h3><a name="action">A warning about some action not found occurs,
like &quot;Warning: Actions not found: ModeOpenCompound&quot;</a></h3>

<dl>
<dt>POSSIBLE CAUSE:
<dd>You didn't install the current app-defaults file.

<p>
<dt>SOLUTION:
<dd>Install the app-default file (<tt>Fig.ad</tt>)
which comes with the <b>xfig</b>.  
<br>
This is most easily done with &quot;<tt>make install</tt>&quot;.
</dl>

<li>
<h3><a name="xclip">X error occurs with <tt>X_SetClipRectangles</tt> as the Request code,
or thick line shows through arrowhead in certain orientations</a></h3>

<dl>
<dt>POSSIBLE CAUSE:
<dd>In X11R5 Xlib, there was a bug in the clipping algorithm.

<p>
<dt>SOLUTION:
<dd>Switch to X11R6 or apply the following patch to
<tt>mit/lib/X/XPolyReg.c</tt> in the X11R5 library:

<h3><a name="latexfonts">When using LaTeX fonts in <b>xfig</b>
I always end up with PostScript fonts</a></h3>

<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>To put fonts under the control of LaTeX when generating PostScript output,
you must tag the text object as 
&quot;<a href="attributes.html#text-flags">special</a>&quot; and then use
<a href="printing.html#export">Combined PostScript/LaTeX</a> (pstex) 
output mode.
This mode forces special text objects to be passed through to LaTeX,
allowing the use of Math mode and Computer Modern fonts among other things.
</dl>

<li>
<h3><a name="arc-boxes">Arc-boxes don't appear correctly
when viewing an exported PostScript file with GhostScript</a></h3>

<dl>
<dt>POSSIBLE CAUSE:
<dd>Ghostscript version 4.01 has a bug with the <tt>arcto</tt> operators.

<p>
<dt>SOLUTION:
<dd>Get <a href="installation.html#get_ghost">Ghostscript 4.03</a> or newer.
</dl>

<hr>

<li>
<h3><a name="openw_icon">OpenWindows sometimes loses track of <b>xfig</b>'s icon</a></h3>

<dl>
<dt>POSSIBLE CAUSE:
<dd>Cause unknown.

<p>
<dt>SOLUTION:
<dd>Here is a temporary kludge. Place the line:
<p>
<pre>
  Fig*iconPixmap:  <i>your_lib_area</i>/fig.icon.X
</pre>
<p>
in your <tt>.Xdefaults</tt> file and copy the file <tt>fig.icon.X</tt>

</dl>

<hr>

<li>
<h3><a name="hp_cap">On HP machines, the capitalization of some letters in the
 edit text window are wrong</a></h3>

<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>Make sure that the <tt>CompKeyDB</tt> file has the lowercase letter
definitions <i>before</i> the uppercase definitions.
This should be the case for the  <tt>CompKeyDB</tt> file
shipped with <b>xfig</b> 2.1.5 and later.
</dl>

<hr>

<li>
<h3><a name="sol_opt">I get a ridiculous %%BoundingBox in my exported PostScript file</a></h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>The Solaris cc compiler version 4.2 has a bug in the optimizer.  Recompile <b>fig2dev</b>
with only <b>-O2</b> or <b>-O1</b> optimization.
</dl>

<hr>

<li>
<h3><a name="gs550_pattern_bug">Patterns are coming out all black when viewing
the exported PostScript file with ghostscript 5.50</a></h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>Ghostscript versions 5.10-5.50 have a bug which causes this to happen.
<br>
Get a newer version of Ghostscript.
</dl>

<hr>

<li>
<h3><a name="grafbase">I am exporting to the MetaFont format and the generated
file refers to the &quot;grafbase.mf&quot; file which I don't have</a></h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>The grafbase.mf file should be on your system if you have MetaFont, but if
you don't have it you can get it from 
<a href="ftp://ctan.tug.org/tex-archive/graphics/fig2mf/">
ftp://ctan.tug.org/tex-archive/graphics/fig2mf/</a>
</dl>

<hr>

<li>
<h3><a name="pulldown">My pulldown menus don't work under CDE</a></h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>Under CDE you must turn off the <b>Num Lock</b> and <b>Caps Lock</b> keys
for the pulldown menus to work.
</dl>

<hr>

<li>
<h3><a name="mntext">I am getting get "mn" in my LaTeX text</a></h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>
The problem is in the \smash part of a command that was generated in
the latex part of the export.  If the <tt>\mddefault</tt> and <tt>\updefault</tt> are
not set up properly on your system you need to define them to do nothing.
</dl>

<li>
<h3><a name="gs700_pattern_bug">Pattern fills are going beyond the bounds of the polygons when I 
export to EPS, GIF, etc., although they look fine on the screen</a></h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>Ghostscript versions 7.00 has a bug (#418928) which causes this to happen.
<br>
Get a newer version of Ghostscript.
</dl>

<hr>

<li>
<h3><a name="superclass">xfig says:
	&quot;Warning: Representation size 4 must match superclass's to override underline&quot;</a>
</h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>The 3D menu widget (smeBSBObject) was used instead of the
2D version or vice versa (check -DXAW3D in Imakefile/Makefile)
<br>
Don't mix the 2D and 3D widget libraries (Xaw and Xaw3d) and header files.

	&quot;can't open file: /usr/X11R6/lib/X11/fig2dev/en_US.ps&quot; 
	(or some other xx_xx.ps file)</a>
</h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>This seems to happen only on RedHat systems.  I believe that they have
enabled internationalization even when it shouldn't be, and it is looking
for a non-existent font encoding file.
<br>
Download newer versions of xfig and transfig RPMs from RedHat.
</dl>

<li>
<h3><a name="XUSERFILESEARCHPATH">
	xfig won't find the app-defaults file in my personal directory
	even though I have set the <b>XAPPLRESDIR</b> environment variable</a>
</h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>If you are using Sun's Openwindows X server you need to set a different 
environment variable, <b>XUSERFILESEARCHPATH</b> to point to your personal
app-defaults directory, and append a &quot;%N&quot; to the path, e.g. 
<blockquote>
<tt>setenv XUSERFILESEARCHPATH $HOME/app-defaults/<b>%N</b></tt>
</blockquote>
</dl>

<!-- ********************** -->
<li>
<h3><a name="multi-key">I can't enter special characters such as a-umlaute in the popup
		editor for text objects.</h3>
<dl>
<dt>POSSIBLE CAUSES AND SOLUTIONS:
<dd>
<ol>
<li>
The <b>CompKeyDB</b> file may not be installed.  This is the file that tells
xfig how to handle the multi-key sequences to produce the Latin-1 characters
such as 
<IMG SRC="images/a-umlaut.png" ALT="a umlaut" >
(a-umlaute), <IMG SRC="images/c-cedilla.png" ALT="c cedilla" align=top> 
(c-cedilla), etc. You should do a <tt>make install</tt> to fully
install xfig and its support files.
<li>
Your keyboard doesn't have a <b>&quot;Multi_key&quot;</b> key.  On some systems
(e.g. Sun Sparcstations), there is a compose key or &quot;Multi_key&quot; which handles these sequences.
If your keyboard doesn't have such a key you can remap another key (e.g. the &quot;Windows&quot;
keys, known to the X server as <b>Super_L</b> and <b>Super_R</b> to the Multi_key using 
the <b>xmodmap</b> program:
<p>
<tt>
xmodmap -e &quot;keysym Super_L = Multi_key&quot;
<br>
xmodmap -e &quot;keysym Super_R = Multi_key&quot;
</tt>
</ol>
</dl>

<!-- ********************** -->
<li>
<h3><a name="validator">When I enter values in the &quot;spinner&quot; widgets,
the digits are entered in reverse order.</h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>
There is a bug in the RedHat Xaw Athena widget set.  Any of the Xaw3d (3-D) Athena
widget sets will work properly.
Uncomment the  &quot;#define XAW3D&quot; line in the Imakefile and recompile xfig 
according to the instructions in the <tt>README</tt> file.
</dl>

<!-- ********************** -->
<li>
<h3><a name="ogonek">LaTeX asks for missing macro \k <i><b>or</b></i> the ogonek diacritic mark
isn't visible.</h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>
Define the macro <tt>\def\k#1{\c{#1}}</tt> before the <tt>\begin{document}</tt> directive
in your LaTeX document.
</dl>

<!-- ********************** -->
<li>
<h3><a name="fonts">Text is positioned differently when exported than it is on the screen</h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>
Your X server (screen) fonts may not be the same as the PostScript fonts that fig2dev
uses when exporting.  If you use the ghostscript fonts in your X server things will
improve.  To do this, see 
<a href="installation.html#install-ghostfonts">Installing Ghostscript's Type1 fonts under X.</a>
</dl>

<!-- ********************** -->
<li>
<h3><a name="fvwm">I cannot type anything into the popup dialogs in xfig when I use the fvwm window manager</h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>
There have been reports of this problem when using the fvwm window manager, possibly under Cygwin.
Try mwm or twm or KDE.
</dl>

<!-- ********************** -->
<li>
<h3><a name="arrow_scroll">When I start xfig I get the message: &quot;Warning: Actions not found: StartScroll&quot;</h3>
<dl>
<dt>POSSIBLE CAUSE AND SOLUTION:
<dd>
When the Xaw or Xaw3d Athena widget sets are compiled with the <b><t>ARROW_SCROLLBAR</t></b> style of
scrollbars there is no <t>StartScroll</t> action and you won't be able to scroll using the 
wheel on the mouse.  
If you want to be able to scroll using the wheel, you must recompile the Xaw library from 
sources, disabling the <b><t>ARROW_SCROLLBAR</t></b> option.
<br>
From xfig version 3.2.5 on, it checks if this action exists and doesn't give the warning.

<h3><a name="xpointer"><tt>XPointer</tt> is undefined or unknown when

<dl>
<dt>POSSIBLE CAUSE:
<dd>You are probably trying to compile <b>xfig</b> on an old OpenWindows
system which doesn't have the <tt>XPointer</tt> typedef.

<p>
<dt>SOLUTION:
<dd>You will have to either upgrade to a newer version of OpenWindows
or switch to the public X server from the
<a href="http://www.camb.opengroup.org/x/">Open Group</a>.
</dl>

<li>
<h3><a name="get_appl">On Sun machines the linker may give erroneous 
error messages about <tt>_get_applicationShellWidgetClass</tt> and 
<tt>_get_wmShellWidgetClass</tt> are undefined</a></h3>

<dl>
<dt>POSSIBLE CAUSE:
<dd>It is a problem with the Sun shared libraries
and the way X11 builds the shared Xmu library.

<p>
<dt>SOLUTION:
<dd>It doesn't affect the operation of <b>xfig</b> and you can ignore it.
<p>
Or you may compile with &quot;<tt>-Bstatic -lXmu -Bdynamic</tt>&quot;.
<p>
To really solve the problem if you are using OpenWindows 3.0
(X11R4-based Xt), please contact your local Sun office and request the
following patches:
<p>
<pre>
     Patch i.d.      Description
     100512-02       4.1.x OpenWindows 3.0 libXt Jumbo patch
     100573-03       4.1.x OpenWindows 3.0 undefined symbols when using
			     shared libXmu
</pre>

<p>
A source patch for use with the MIT X11R4 libraries was developed by
Conrad Kimball (cek@sdc.boeing.com); it retrofits into R4 some fixes
made in R5 to get around this problem. The patch is on export in [1/93]
<tt>contrib/X11R4_sunos4.1.2_patch_version3.Z</tt>.
<p>
The other option is to use X11R5 or X11R6.

<dl>
<dt>POSSIBLE CAUSE:
<dd>On most Linux machines, there is an old version of the JPEG library
already installed, and is incompatible with <b>xfig</b>.
<b>xfig</b> can't use a JPEG library older than Version 5b.

<p>
<dt>SOLUTION:
<dd>Delete its library files (usually <tt>/usr/local/lib/libjpeg.so</tt>
and <tt>/usr/local/lib/libjpeg.a</tt>)
and the header file (usually <tt>/usr/local/include/jpegdata.h</tt>).

<br>
w_menuentry.c:143: structure has no member named `international'
</blockquote>

<dl>
<dt>POSSIBLE CAUSE:
<dd>You probably have an old version of the 3D Athena Widget set (Xaw3d)
which doesn't have the <tt>fontset</tt> and <tt>international</tt> components,
but your Intrinsics library <b>does</b> have those components.

<p>

<dd>Either get a newer version of the Xaw3d widgets from 
<a href="ftp://ftp.x.org/contrib/widgets/Xaw3d">ftp://ftp.x.org/contrib/widgets/Xaw3d</a>
or use your system's 2D Athena widgets (Xaw).
The latter is acheived by:
<br>
1. commenting out the &quot;XAWLIB = -lXaw3d&quot; line in the Imakefile,
<br>
2. doing a &quot;rm w_menuentry.o&quot;,
<br>
3. &quot;make Makefile&quot;
