Hi,
Hans Otared and thank you for your suggestions.
A question for Hans : why my code does not give the expected result ?

Hi fabrice,

I dont’t know whether this the best solution, but you can use the following definition of the MPgraphic Funny:

\startuseMPgraphic{Funny}
     interim linecap := butt ;
     path p ;
     p := unitsquare xyscaled (OverlayWidth,OverlayHeight) ;
     drawoptions (withpen pencircle scaled 6.5pt withcolor \MPcolor{MyColorA}) ;
     draw lrcorner p --urcorner p --ulcorner p withcolor white;
     draw ulcorner p --llcorner p ;

\stopuseMPgraphic

\startuseMPgraphic{Funny}
    interim linecap := butt ;
    draw leftboundary OverlayBox ;
    setbounds currentpicture to OverlayBox ;
\stopuseMPgraphic
