[NTG-context] Textext Question

[Renaud AUBIN]

draw + drawdblarrow = ?!

\setupoutput[pdftex]
\runMPgraphicstrue
\setuppapersize[S6][S6]

\setupcolors[state=start]

\startMPinclusions
 numeric u; u=.8cm;
path AX; AX =  (10u,0) -- (0,0) -- (0,10u);
\stopMPinclusions

\starttext
\startuseMPgraphic{dummy}

pickup pencircle scaled 1mm;
drawdblarrow AX withcolor blue;
 label.rt(textext("$3x2+\pi$"), (5u,6u));
\stopuseMPgraphic

\placefigure[left]{bla.bla}{\useMPgraphic{dummy}}
 
\input dawkins
\stoptext

works...

Cheers,

Renaud
