Hello,
Is it possible to calculate the position of something in Metapost, and to export that value to TeX such that I can use it in setups and things?
it depends on what you want to calculate
\startMPcalculation path p, q;
h := PaperHeight; w := PaperWidth;
p = (0, 0) -- (w, .5h); q = (0, h) -- (w, 0);
z0 = p intersectionpoint q;
passvariable("z",ypart z0) ; \stopMPcalculation
\setuplayout [topspace=0pt, header=0pt, height=\MPrunvar{z}bp]
\showgrid
\starttext xyz:\MPrunvar{z} \stoptext
Wonderful! -- Kate
