I can draw the Nike logo in usual way.

\documentclass[tikz,border=5mm]{standalone}
\usetikzlibrary{decorations.pathreplacing,calligraphy}
\begin{document}
\begin{tikzpicture}
%https://c.static-nike.com/a/images/w_1920,c_limit/bzl2wmsfh7kgdkufrrjq/image.jpg
\clip (-4.5,-2.5) rectangle (4.5,2.5);
% 2 vertices
\path
(-2.33,1.19) coordinate (A)
(3.45,1.18) coordinate (B);
% draw the Nike logo in usual way
\fill[orange] (A)
..controls +(-116:2.45) and +(-165:4.8) .. (B)
..controls +(-153:7.4) and +(-131:3.5) .. cycle
;
\end{tikzpicture}
\end{document}
Now I wish to draw it using calligraphy library of TikZ, so I need to define a based curve and a pen. A based curve is something like the following black curve
\def\nikecurve{(A) ..controls +(-123:3.5) and +(-158:4.8) ..(B)}
\draw \nikecurve;
Question 1: How to define a pen (name nikepen) in order to draw the Nike logo by a single command
\pen[pen name=nikepen] ....
\calligraphy[pen colour=orange] \nikecurve;
Question 2: Can we do it with some pen (or material) in Asymptote ?
Note:
- The way in this link is complex. I think
calligraphymay be simpler. - I just take the Nike logo for an simple example. Solutions are expected to be applicable to general situations (see another example, Dove's logo below) as if we have a pen of fine controls of (smoothly) varying thickness and varying colors.
