Hello all, I'm learning a little bit of metapost language, using metafun manual. I made some background for a title (surely the code is awful, thanks for suggestions of improvement) but it's static, i'd like to adapt it to the widthof the text. I don't know if it is possible from my code and if it is i don't know how to do ! Thanks for any help, best regards, Roland My code : \setuplayout[width=fit,height=fit,header=0cm,topspace=1.8cm,footer=1.2cm,% bottomspace=1cm,backspace=6cm,leftmargin=1.5cm, leftmargindistance=0.5cm,rightmargin=1cm,rightmargindistance=0.5cm, location=singlesided] \startuniqueMPgraphic{essai} path p,p',q,q'; p:=(0,0.1cm)--(12cm,0.3cm); q:=(11cm,-0.7cm)--(11.5cm,2.2cm); p':=(11.7cm,1.3cm)--(-0.4cm,1.4cm); q':=(0.3cm,2.4cm)--(0.2cm,-0.3cm); draw p withpen pencircle scaled 1mm withcolor 0.3white; draw p' withpen pencircle scaled 1mm withcolor 0.3white; draw q withpen pencircle scaled 1mm withcolor 0.3white; draw q' withpen pencircle scaled 1mm withcolor 0.3white; pair A; A:=q'intersectionpoint p'; pair B; B:=q intersectionpoint p'; pair C; C:=p intersectionpoint q; pair D; D:=q'intersectionpoint p; path s; s:= A--B--C--D--cycle; fill s withcolor .8white; \stopuniqueMPgraphic \starttext \defineoverlay[encadrement][\uniqueMPgraphic{essai}] \framed[frame=off,background=encadrement]{\it\tfb\color[darkred]{Devoir de mathématiques}} \stoptext
