%\LPack{pst-func} loads by default the following packages: \LPack{pst-plot},
%\LPack{pstricks-add}, \LPack{pst-math}, \LPack{pst-xkey}, and, of course \LPack{pstricks}.
%All should be already part of your local \TeX\ installation. If not, or in case
%of having older versions, go to \url{http://www.CTAN.org/} and load the newest version.

\section{Syntax of \Lcs{psDart}}
\begin{BDef}
\Lcs{psDartBoard}\OptArgs\OptArg*{$(x_0,y_0)$}
\end{BDef}
\section{Examples}
\subsection{The default size}
\begin{LTXexample}
\begin{pspicture}[showgrid](-3,-3)(9,3)
\psDartBoard % The default Dartboard (radius=2.1cm)
\psDartBoard[fontsize=7pt](6cm,0)
\end{pspicture}
\end{LTXexample}
\subsection{Scaling}
\begin{LTXexample}[pos=r,width=0.58\linewidth]
\begin{pspicture}[showgrid](-5,-5)(5,5)
\psDartBoard[unit=2]
\end{pspicture}
\end{LTXexample}
\begin{LTXexample}[pos=r,width=0.58\linewidth]
\begin{pspicture}[showgrid](-5,-5)(5,5)
\psDartBoard[fontsize=15pt,unit=2]
\end{pspicture}
\end{LTXexample}
\subsection{Space}
\Lcs{psDartBoard} itself uses internally already an environment \Lenv{pspicture} which
reserves the space. But an internal \Lcs{rput} command places the dartboard without specifying
coordinates at the origin which is the reason why one has to reserve space with an additional
environment \Lenv{pspicture} as can be seen in the above examples..
%\psset{unit=1cm}
\section{Darts}
\begin{pspicture}[showgrid](0,-1)(\linewidth,8)
\psDart(4,2)
\psDart[dartcolor=green,rot=22.50](4,2)
\psDart[dartcolor=blue,rot=45](4,2)
\psDart[rot=-90,unit=0.75](2,8)
\end{pspicture}
\begin{lstlisting}
\begin{pspicture}[showgrid](0,-1)(\linewidth,8)
\psDart(4,2)
\psDart[dartcolor=green,rot=22.50](4,2)
\psDart[dartcolor=blue,rot=45](4,2)
\psDart[rot=-90,unit=0.75](2,8)
\end{pspicture}
\end{lstlisting}
\section{Board and Darts}
\begin{LTXexample}[pos=t]
\begin{pspicture}(-5,-5)(5,5)
\psDartBoard[fontsize=15pt,unit=2]
\psDart[rot=45,unit=0.5](0,0)
\psDart[rot=30,unit=0.5,dartcolor=blue](0,0)
\psDart[rot=80,unit=0.5,dartcolor=green](-2,2)
\end{pspicture}
\end{LTXexample}
%\begin{LTXexample}[pos=r,width=0.6\linewidth]
%foo\psDart bar
%\end{LTXexample}
\section{Changing the viewpoint}
You can change the viewpoint with the two optional arguments \Lkeyword{preCode}\footnote{There is also a \Lkeyword{postCode},
which is not of real interest here.}
which allow to change the transformation matrix of PostScript. However, it does \emph{not} work
with \XeLaTeX, you have to choose the Sequenz \texttt{latex}$\rightarrow$\texttt{dvips}$\rightarrow$\texttt{ps2pdf}.
\begin{LTXexample}[pos=t]
\begin{pspicture}(-4.5,-4.5)(4.5,4.5)
\psDartBoard[preCode={[1 0.2 0.5 1 0 0 ] concat },fontsize=18pt,unit=1.5]
\psDart[unit=0.5,rot=45](1,-1)
\end{pspicture}
\end{LTXexample}
