Also:
\starttext
\startMPpage
% puts the center of the bbox of path p at the point t
primarydef p centered t =
hide(xshift := xpart t - (xpart urcorner p + xpart llcorner p)/2 ;
yshift := ypart t - (ypart urcorner p + ypart llcorner p)/2 ; )
p shifted (xshift,yshift)
enddef;
draw fullsquare scaled 2cm shifted (50,3) centered (100,100);
% just for reference:
drawdot origin withpen pencircle scaled 10 withcolor red;
drawdot (100,100) withpen pencircle scaled 10 withcolor green;
\stopMPpage
\stoptext
(I thought there was a metafun definition for that but I cannot find it).
Best wishes,
Taco
