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

ATTRIBUTES

   points
       Set/Get the arrayref of points that make up this Polygon.

METHODS

   new
       Creates a new Geometry::Primitive::Polygon

   area
       Area of this polygon.  Assumes it is non-self-intersecting.

   add_point
       Add a point to this polygon.

   clear_points
       Clears all points from this polygon.

   point_count
       Returns the number of points that bound this polygon.

   get_point
       Returns the point at the specified offset.

   point_end
       Get the end point.  Provided for Shape role.

   point_start
       Get the start point.  Provided for Shape role.

   scale ($amount)
       Scale this this polygon by the supplied amount.

NAME

       Geometry::Primitive::Line - A Line

DESCRIPTION

       Geometry::Primitive::Line represents a straight curve defined by two points.

SYNOPSIS

	 use Geometry::Primitive::Line;

	 my $line = Geometry::Primitive::Line->new();
	 $line->start($point1);
	 $line->end($point2);

ATTRIBUTES

   end
       Set/Get the end point of the line.

   start
       Set/Get the start point of the line.

METHODS

   new
       Creates a new Geometry::Primitive::Line

   contains_point
       Returns true if the supplied point is 'on' the line.  Accepts either a point object or an x y pair.

   grow
       Does nothing, as I'm not sure how.  Patches or hints welcome.

   is_parallel ($other_line)
       Returns true if the supplied line is parallel to this one.

   is_perpendicular ($other_line)
       Returns true if the supplied line is perpendicular to this one.

   length
       Get the length of the line.

   point_end
       Get the end point.  Provided for Shape role.

   point_start
       Get the start point.  Provided for Shape role.

   scale
       Does nothing at the moment.

   slope
       Get the slope of the line.

   to_string
       Guess!

   y_intercept
       Returns the Y intercept of this line.
