With ConTeXt you can include your MetaPost code in the document and the graphic is generated at runtime. \startuseMPgraphic{hexagon} theta := 360/7; radius := 1in; z0 = origin; z1 = z0 + dir(90)*radius; z2 = z0 + dir(90 + theta)*radius; z3 = z0 + dir(90 + 2*theta)*radius; z4 = z0 + dir(90 + 3*theta)*radius; z5 = z0 + dir(90 + 4*theta)*radius; z6 = z0 + dir(90 + 5*theta)*radius; z7 = z0 + dir(90 + 6*theta)*radius; draw (z1 -- z2 -- z3 -- z4 -- z5 -- z6 -- z7 -- cycle) xysized(OverlayWidth,OverlayHeight) ; \stopuseMPgraphic \defineoverlay[hexagon][\useMPgraphic{hexagon}] \setupbackgrounds[page][background=hexagon] \starttext \page[empty] \stoptext For more information about MetaPost graphics take a look into the MetaFun manual (http://pragma-ade.com/show-man-7.htm) which provides many examples.
