About filling paths, unfill, etc.
Hi everyone. I want to know if nowadays (2020) Metafun is able to do an actual unfill, like above: https://tex.stackexchange.com/questions/151068/how-can-i-fill-a-complex-path... Example of what I want to do: \startMPpage path A, B, C; A := unitcircle shifted (-center unitcircle); A := A scaled 4cm; B := unitcircle shifted (-center unitcircle); B := B scaled 1cm; %C := (reverse B) shifted (left*1.4cm); %It works for two paths fill (reverse B)-- A -- cycle withcolor red; %fill A -- (reverse B) -- C -- cycle withcolor red; %When I try the same with three paths, a thin, unwanted line appears \stopMPpage I'm aware of unfill and I've read somewhere else about using pens instead, but I want to know if a better solution is possible. Thank you in advance. Regards, Jairo :)

Example of what I want to do:
\startMPpage
path A, B, C;
A := unitcircle shifted (-center unitcircle);
A := A scaled 4cm;
B := unitcircle shifted (-center unitcircle);
B := B scaled 1cm;
%C := (reverse B) shifted (left*1.4cm);
%It works for two paths
fill (reverse B)-- A -- cycle withcolor red;
%fill A -- (reverse B) -- C -- cycle withcolor red;
%When I try the same with three paths, a thin, unwanted line appears
\stopMPpage
I'm aware of unfill and I've read somewhere else about using pens instead, but I want to know if a better solution is possible. Thank you in advance. \startMPpage path A; A := (unitcircle shifted (-center unitcircle)) scaled 4cm; path B; B := (unitcircle shifted (-center unitcircle)) scaled 1cm; path C; C := B shifted (left*1.4cm);

Oh, cool. I've found some info in the Metafun manual too. I should read more carefully next time. Thank you very much! Jairo :) El mar., 3 de nov. de 2020 a la(s) 07:29, Hans Hagen (j.hagen@xs4all.nl) escribió:
