NAME
Geometry::Primitive::Polygon - Closed shape with an arbitrary number of points.DESCRIPTION
Geometry::Primitive::Polygon represents a two dimensional figure bounded by a series of points that represent a closed path.SYNOPSIS
use Geometry::Primitive::Polygon; my $poly = Geometry::Primitive::Polygon->new; $poly->add_point($point1); $poly->add_point($point2); $poly->add_point($point3); # No need to close the path, it's handled automatically
