Method Detail
buildSegmentsFromCurvePoints()method
public static function buildSegmentsFromCurvePoints(graphicPoints:Array, tension:Number = .25):Array

Converts an Array of GraphicPoints into a series of curveTo commands that can then be used to draw a curve to a graphics context.

Parameters

graphicPoints:Array — The Array of GraphicPoints to draw the curve between.
 
tension:Number (default = .25) — A value between 0 and 1 representing the rigidity of the curve. A tension of 1 will produce a straight line while a tension of 0 will result in a highly curved Bezier curve.

Returns
Array
