The "closepath" command

Command
-

- SVG 2 adds the ability to fill in missing coordinate data with - the Z or z command to avoid the - need to add a zero length (or very short in the case of relative - paths with rounding errors) path segment to close a subpath. This - can effect the number of markers drawn and their orientation at - the beginning/end of a closed subpath. -

- The use of Z or z to replace - missing coordinate data with the coordinate of the initial point in - a subpath was resolved at the - Sydney - (2015) meeting. -

A closed subpath must be closed with a "closepath" command, this "joins" the first and last path segments. Any other path is an open subpath.
