hi I have again another metapost problem: I made the following picture: \setupoutput[pdftex] \starttext \setupcolors[state=start] \startMPpage path p; p := fullsquare xysized(2cm,2cm); fill p scaled 2 withcolor blue; path a,b,c; for i=0 step 1 until 9: a:= p enlarged (5mm-10mm*i/9,5mm-10mm*i/9); b:= a enlarged (-10mm/9,-10mm/9); c:= a --reverse b--cycle; fill c withcolor transparent(1,i/9,white); endfor; \stopMPpage \stoptext when I compile it an look at the result then the stripes are overlapping a little bit. how can I do this so that one stripe is next to the other without overlapping,but without a spece between them. greetings severin
