Hi,
I try to fill the two intersection areas of two ring shapes (ie. an area
bounded by two concentric circles). Here is a little tikz code to give
you an idea of the problem:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\pagestyle{empty}
\begin{tikzpicture}
\filldraw[fill=red,even odd rule]
(0,0) circle (2.5cm) (0,0) circle (3cm)
(2,0) circle (2.5cm) (2,0) circle (3cm);
\end{tikzpicture}
\end{document}
So what I want is to have the intersection which does _not_ get filled
in the example above filled red, whereas the rest of the ring areas,
which is now filled red, should stay transparent. Any idea how to
achieve this? BTW, I'm using pgf-2.0.
Regards,
Dominique Würtz
