Hello,
Is it possible to use the eofill extension in this code ? I tried without
success. Thank you.
Fabrice

\starttext
\startMPcode
   path carre, disque;

   carre = fullsquare scaled 200;
   disque = fullcircle scaled 200;

   draw carre numberstriped (.25,15,5) withcolor \MPcolor{magenta};
   fill disque withcolor white;

   draw carre  withcolor \MPcolor{orange};
   draw disque  withcolor \MPcolor{orange};

   path a[];
   a1 = origin -- point 3.5 of carre;

   interim ahangle := 30;
   drawdblarrow a1 withpen pencircle scaled 1.5pt withcolor darkred;
   label.top("$R$", point 1/2 of a1);
\stopMPcode
\stoptext

No, eofill is basically just a frontend for the PDF primitive eofill,
which works on a single connected path that intersects itself.

If that wasn't enough, the numberstriped instruction does not return a
path but a picture and pictures are immutable.
