__construct($vertices)

Parameters:

• $vertices – array - (optional)

getVertices()

Returns the polyline’s local vertices without scaling or rotation and without being offset by the polyline position.

Returns:float[]

getTransformedVertices()

Returns:float[] vertices scaled, rotated, and offset by the polyline position.

getLength()

Returns:float Returns the euclidean length of the polyline without scaling

getScaledLength()

Returns:float Returns the euclidean length of the polyline
