Re: [NTG-context] A dumb question about MetaFun
I found another workaround, but I'm going to try this. Thank you, Keith, and thank you, Taco.

Re: [NTG-context] A dumb question about MetaFun
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

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 :)
