The line cap style determines the shape applied to the open endpoints of a stroked path. A value of 0 produces a butt cap flush with the endpoint; 1 produces a round cap centred on the endpoint; 2 produces a square cap extending half the line width beyond the endpoint.

The cap style affects only open subpath endpoints, not joins between connected segments.
