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?
