-<title>UK TeX FAQ -- question label divzero</title>

-<h3>Graphics division by zero</h3>
-<p/>While the error
-<blockquote>
-<pre>
-! Package graphics Error: Division by 0.
-</pre>
-</blockquote><p>
-can actually be caused by offering the package a figure which claims
-to have a zero dimension, it&#8217;s more commonly caused by rotation.
-<p/>Objects in TeX may have both height (the height above the baseline)
-and depth (the distance the object goes below the baseline). If you
-rotate an object by 180 degrees, you convert its height into depth,
-and vice versa; if the object started with zero depth, you&#8217;ve
-converted it to a zero-height object.
-<p/>Suppose you&#8217;re including your graphic with a command like:
-<blockquote>
-<pre>
-\includegraphics[angle=180,height=5cm]{myfig.eps}
-</pre>
-
-</blockquote><p>
-In the case that <i>myfig.eps</i> has no depth to start with, the
-scaling calculations will produce the division-by-zero error.
-<p/>Fortunately, the <i>graphicx</i> package has a keyword
-<code>totalheight</code>, which allows you to specify the size of the
-image relative to the sum of the object&#8217;s <code>height</code> and
-<code>depth</code>, so
-<blockquote>
-<pre>
-\includegraphics[angle=180,totalheight=5cm]{myfig.eps}
-</pre>
-
-</blockquote><p>
-will resolve the error, and will behave as you might hope.
-<p/>If you&#8217;re using the simpler <i>graphics</i> package, use the
-<code>*</code> form of the <code>\</code><code>resizebox</code> command to specify the use of
-<code>totalheight</code>:
-<blockquote>
-<pre>
-\resizebox*{!}{5cm}{%
- \rotatebox{180}{%
- \includegraphics{myfig.eps}%
- }%
-}
-</pre>
