filled_polygon — ANNOTATE shape op

• Data kinds: image2d × pairs → image2d

• Call: import fullseye as fs; fs.ledger.filled_polygon(img, points, color='neutral', alpha=1.0, scheme='okabe_ito') (to call the implementation directly, import annotate; annotate.filled_polygon(img, points, color='neutral', alpha=1.0, scheme='okabe_ito'); from the registry, opsannotate.get("filled_polygon"))

Usage

A filled polygon (even-odd crossing rule — imagedraw only outlines).

Parameters

points : (N,2)

Sequence of (x,y) vertices (closed automatically). Fewer than 3 points is a ValueError.

Raises

ValueError

fewer than 3 points / non-finite / alpha outside [0,1].
