NAME
Geometry::Primitive::Arc - Portion of the circumference of a CircleDESCRIPTION
Geometry::Primitive::Arc represents a closed segment of a curve.SYNOPSIS
use Geometry::Primitive::Arc; my $arc = Geometry::Primitive::Arc->new( angle_start => 0, angle_end => 1.57079633, radius => 15 );
ATTRIBUTES
angle_start
The starting angle for this arc in radians.angle_end
The ending angle for this arc in radians.radius
Returns the radius of the arc.origin
Set/Get the origin of this arc.METHODS
new
Creates a new Geometry::Primitive::Arcget_point_at_angle
Given angle in radians returns the point at that angle on this arc. Returns undef if the angle falls outside this arc's range.length
Returns the length of this arc.point_end
Get the end point. Provided for Shape role.point_start
Get the start point. Provided for Shape role.scale ($amount)
Increases the radius by multiplying it by the supplied amount.AUTHOR
