Hi list! A simple question: is there an equivalent of thetextext for a
normal picture (an "image(draw ... ;)")? I want to move the center of a
picture to an specific point, like this:
\startMPpage
draw thetextext("\tttf hello", origin) ;
draw unitsquare scaled 1cm;
\stopMPpage
The "hello" is centered at the origin. I want to achieve the same result
for pictures. I've seen such a command some time ago, but I've forgotten
and I cannot find it again in documentation. Thanks and sorry for any
inconvenience.
Regards,
Jairo :)

Jairo
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.
Best Wishes
Keith

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

I found another workaround, but I'm going to try this. Thank you, Keith,
and thank you, Taco.
Cordially,
Jairo :)
