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 ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
