Detailed Description

A polyline is drawn as a set of ordered vertices relative to the shape's x,y coordinate.

Polylines may be filled or unfilled. An unfilled polyline is more conceptually familiar with what is implied by a polyline. A filled polyline is essentially an unclosed polygon.

Unfilled Polyline

Filled Polyline
