// polyline is a set of points var polyline = [[0,2], [3,4], [7,8]]; // fat is a factor corresponding to the width of the polyline var fat = 5; // polygon is an array of points outlining a polygon that completely encompasses a line var polygon = plumper(polyline, fat); // if you're OK with slighly larger number of polygons, but you care about speed var polygon = plumper(polyline, fat, false);
