If the parameter <em class="parameter"><code>use.role.for.mediaobject</code></em> is
non-zero, then the <code class="literal">role</code> attribute on
<code class="sgmltag-element">imageobject</code>s and other objects within a
<code class="sgmltag-element">mediaobject</code> container will be used to select which object
will be used. If one of the objects has a role value that matches the
<em class="parameter"><code>preferred.mediaobject.role</code></em> parameter, then it
has first priority for selection. If more than one has such a role
value, the first one is used.
</p><p>
See the <em class="parameter"><code>use.role.for.mediaobject</code></em> parameter
for the sequence of selection.</p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="make.graphic.viewport.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="graphics.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="link.to.self.for.mediaobject.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">make.graphic.viewport </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> link.to.self.for.mediaobject</td></tr></table></div></body></html>
