Defined in:

Overview

Converts an array of Path::Command objects into an array of Fontisan::Ufo::Contour objects.

Tracks current-point, subpath-start, and previous-control-point state to resolve relative coordinates and smooth-curve reflections.

Point type mapping (Ufo::Point types):

M (first in subpath) → first point of contour, type "line"
L / H / V            → "line"
C                    → "offcurve", "offcurve", "curve"
S                    → reflected "offcurve", "offcurve", "curve"
Q                    → "offcurve", "qcurve"
T                    → reflected "offcurve", "qcurve"
Z                    → closes the contour (no point emitted)
