\section{Basic Functionality}

a plain circle:\\
\begin{mpostfig}
draw fullcircle scaled unit;
label(btex 1 etex, (0,0));
\end{mpostfig}

scaled (and aligned to centre if available):\\
X
\begin{mpostfig}[opt={scale=1.5,\align}]
draw fullcircle scaled unit;
label(btex 2 etex, (0,0));
\end{mpostfig}
X

declare figure with label (no display).
\begin{mpostfig}[label={fig}]
draw fullcircle scaled unit;
label(btex 3 etex, (0,0));
\end{mpostfig}

display:\\
\mpostuse{fig}

display with options:\\
\mpostuse[scale=1.5,\align]{fig}

display in a box:\\
\fbox{\mpostuse{fig}}

centred display:
\begin{center}
\mpostuse[scale=1.5]{fig}
\end{center}

display in equation (align if possible):
\begin{equation}
\mpostuse[scale=1.5,\align]{fig}
\end{equation}

filename: \mpostgetname{fig}
\texttt{\mpostfigurename}

figure with filename:\\
\begin{mpostfig}[file={\jobname-name.mps},label={name},show]
draw fullcircle scaled unit;
label(btex 4 etex, (0,0));
\end{mpostfig}
\\
filename: \mpostgetname{name}
\texttt{\mpostfigurename}

display by \verb+\includegraphics+ (if file exists):\\
\IfFileExists{\jobname-name.mps}{\includegraphics{\jobname-name.mps}}{}

label does not exist:\\
\mpostuse{notexist}

utf-8 test:\\
\begin{mpostfig}
interim unit:=1.5cm;
draw fullcircle scaled unit;
label(btex àáâãäåæ etex, (0,0));
\end{mpostfig}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\section{Immediate Processing}

immediate processing per figure:\\
\begin{mpostfig}[now]
interim unit:=1.5cm;
draw fullcircle scaled unit;
label(btex 5 etex, (0,0));
\end{mpostfig}

turn on immediate processing for all figures and keep sources.
\mpostsetup{nowall,nowkeep}

generate file \texttt{\jobname-now.mps}:
\begin{mpostfig}[file={\jobname-now.mps}]
draw fullcircle scaled unit;
label(btex 6 etex, (0,0));
\end{mpostfig}
\\
display by \verb+\includegraphics+:\\
\includegraphics{\jobname-now.mps}
\\
source \texttt{\jobname-now.mp}
\IfFileExists{\jobname-now.mp}{exists}{does not exist}.

turn off immediate processing and discard sources.
\mpostsetup{nowall=false,nowkeep=false}
