I found another workaround, but I'm going to try this. Thank you, Keith, and thank you, Taco. Cordially, Jairo :) El dom., 16 de ago. de 2020 3:36 p. m., Taco Hoekwater escribió:

Try

draw unitsquare scaled 1cm shifted (xcm, ycm);

Page 11 of the manual metafun-p.pdf is your friend here. My recent conversation with Taco on this list will be usefull as well.

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
