pub fn contour_to_arc_ring(
contour: &Contour,
tolerance: Tolerance,
) -> GeomResult<ArcRing>Expand description
Convert one closed contour into an arc ring.
Returns the ring in contour order, one vertex per joint. Segment
endpoints must already meet, within tolerance or within the rounding of
their own evaluation, whichever is larger (see the module notes on
Tolerance::ZERO); gaps are reported rather than closed, because a
silently bridged gap changes the profile the caller asked for.
