NAME

       Graphics::Primitive::Path - Collection of primitives

DESCRIPTION

       Graphics::Primitive::Path is a shape defined by a list of primitives.

SYNOPSIS

         use Graphics::Primitive::Path;

         my $path = Graphics::Primitive::Path->new();
         $path->add_primitive($line);
         $path->move_to($point);

METHODS

   Constructor
       new Creates a new Graphics::Primitive::Path

   Instance Methods
       add_primitive ($prim)
           Add a primitive to this Path.

       arc ($radius, $start, $end, [ $skip_line_to ])
             $path->arc($radius, $start_angle_in_radians, $end_angle_in_radians);

           Draw an arc based at the current point with the given radius from the given start
           angle to the given end angle.  A line will be drawn from the current_point to the
           start point of the described arc.  If you do not want this to happen, supply a true
           value as the last argument.

       clear_current_point
           Clears the current point on this Path.

       clear_primitives
           Clears all primitives from this Path.  NOTE: This does not clear the current point.

       close_path
           Close the current path by drawing a line from the current_point back to the first
           point in the path.

       contiguous
           Flag this path as being contiguous at this point.  Continuity is important so some
           path-based drivers such as Cairo.  You should not mess with this attribute unless you
           know what you are doing.  It's used for driver hinting.

       current_point
           Returns the current -- or last -- point on this Path.

       curve_to ($control1, $control2, $end)
           Creates a cubic Bézier curve from the current point to the $end point using $control1
           and $control2 as control points.

       ellipse ($width, $height, [ $skip_line_to ])
           Creates an ellipse at the current point with the specified width and height.  Optional
           last argument, if true, skips drawing a line to the ellipse's starting point.

       get_points
           Get this path as a series of points.

       get_primitive
           Returns the primitive at the specified offset.

       hints
           List of hint hashrefs. This hint arrayref matches the primitives arrayref one-to-one.
           Hints are tidbits of information that may assist drivers in optimizing (or
           successfully handling) primitives in this path's list.  You should not mess with this
           structure unless you know what you are doing.

       line_to ($point | $x, $y)
           Draw a line from the current point to the one provided. Accepts either a
           Geoemetry::Primitive::Point or two arguments for x and y.

       move_to ($point | $x, $y)
           Move the current point to the one specified.  This will not add any primitives to the
           path.  Accepts either a Geoemetry::Primitive::Point or two arguments for x and y.

       primitive_count
           Returns the number of primitives on this Path.

       rectangle ($width, $height)
           Draw a rectangle at current_position of the specified width and height.

       rel_curve_to ($x1, $y1, $x2, $y2, $x3, $y3)
           Creates a cubic Bézier curve from the current point using the provided values as
           offsets:

             start = current point
             control1 = current point + $x1,$y1
             control1 = current point + $x2,$y2
             end = current point + $x3,$y3

       rel_line_to ($x_amount, $y_amount)
           Draw a line by adding the supplied x and y values to the current one.  For example if
           the current point is 5,5 then calling rel_line_to(2, 2) would draw a line from the
           current point to 7,7.

       rel_move_to ($x_amount, $y_amount)
           Move to a new point by adding the supplied x and y values to the current ones.
