This class represents Bezier paths that are vector-based paths based on polynomial formulas. Vector paths are the basis of Quartz 2D. As such, this class provides the most general interface to Quartz 2D from Cocoa.

A Bezier path is constructed from path elements. Complex paths are constructed by appending lines and curves to the path. It is also possible to move to a point, thus creating a broken space in the path. Lines are appended to a path using the method lineToPoint:. Curves are appended using the method curveToPoint:controlPoint1:controlPoint2:. To move to a new location on the canvas, use the method moveToPoint:. In all of these methods, the point referred to is the end point of the element; the starting point is implicitly specified as the endpoint of the last element in the path. Chapter 4 provides a more detailed discussion on the use of NSBezierPath for drawing.
