NAME

       Geometry::Primitive::Arc - Portion of the circumference of a Circle

DESCRIPTION

       Geometry::Primitive::Arc represents a closed segment of a curve.

SYNOPSIS

	 use Geometry::Primitive::Arc;

	 my $arc = Geometry::Primitive::Arc->new(
	     angle_start => 0,
	     angle_end => 1.57079633,
	     radius => 15
	 );

ATTRIBUTES

   angle_start
       The starting angle for this arc in radians.

   angle_end
       The ending angle for this arc in radians.

   radius
       Returns the radius of the arc.

   origin
       Set/Get the origin of this arc.

METHODS

   new
       Creates a new Geometry::Primitive::Arc

   get_point_at_angle
       Given angle in radians returns the point at that angle on this arc.  Returns undef if the angle falls outside this arc's range.

   length
       Returns the length of this arc.

   point_end
       Get the end point.  Provided for Shape role.

   point_start
       Get the start point.  Provided for Shape role.

   scale ($amount)
       Increases the radius by multiplying it by the supplied amount.

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.
