Hi,
I tried the "Dcaron" example from the MetaPost manual (page 50) and it
works nicely when called with "mpost".
% Dcaron.mp
fontmapfile"=lm-ec.map";
beginfig(56);
picture q;
path p;
interim ahlength:=12bp;
interim ahangle:=25;
q:= glyph "Dcaron" of "ec-lmr10" scaled .2;
for item within q:
p:= pathpart item;
drawarrow p withcolor(.6,.9,.6) withpen pencircle scaled 1.5;
for j=0 upto length p:
pickup pencircle scaled .7;
draw (point j of p -- precontrol j of p)
dashed evenly withcolor blue;
draw (point j of p -- postcontrol j of p)
dashed evenly withcolor blue;
pickup pencircle scaled 3;
draw precontrol j of p withcolor red;
draw postcontrol j of p withcolor red;
pickup pencircle scaled 2;
draw point j of p withcolor black;
endfor
endfor
endfig;
% -------
But how can I get the glyph path(s) with luatex (mplib)?
Minimal example (glyph.mkiv) and console output are attached (log is
empty). Looks like I can't use 'fontmapfile' and without it the glyphs
are not found.
