Hi, I’m trying to understand MetaPost better.
I’d like to draw a fat line that’s cut at its end points.
You mean like linecap = butt?
Yes, but that doesn’t behave differently.
\startMPpage[offset=5mm] path p;
p := origin -- (7cm,0);
interim linecap := squared;
draw p withpen ((pensquare ) scaled 5mm) withcolor red ; draw envelope ((pensquare ) scaled 5mm) of p withcolor green ; draw envelope ((pensquare rotated eps) scaled 5mm) of p withcolor blue ; \stopMPpage
(there is an "ontarget" chapter about envelopes; mikael and i spent quite some time figuring out a few things but in the end conclused that mp des the right thing given the strategy it folows but it definitely has side effects)
Thank you for the insight, but does that mean I can’t get my “butt capped” lines and I must shorten the lines by half the pen size?

Hraban, with the new upload you can do \startMPpage[offset=1dk] pickup pencircle scaled 4 ; path p ; p := origin -- (20,0) ; draw p withcolor darkyellow ; draw p yshifted 5 withlinecap butt withcolor darkred ; draw p yshifted -5 withlinecap squared withcolor darkgreen ; for i within currentpicture : drawpoints pathpart i withpen pencircle scaled 1 ; endfor ; \stopMPpage That is, you can set linecap for each draw. I hope it helps. /Mikael
