NAME
Geometry::Primitive::Polygon
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 automaticallyMETHODS
