constructCurveXYOffset MethodStatic

Construct curves that are offset from a Path or Loop

• The construction will remove "some" local effects of features smaller than the offset distance, but will not detect self intersection among widely separated edges.
• Offset distance is defined as positive to the left.
• If offsetDistanceOrOptions is given as a number, default options are applied.
• When the offset needs to do an "outside" turn, the first applicable construction is applied:
  • If the turn is larger than options.minArcDegrees, a circular arc is constructed.
  • if the turn is larger than options.maxChamferDegrees, the turn is constructed as a sequence of straight lines that are
    • outside the arc
    • have uniform turn angle less than options.maxChamferDegrees
    • each line segment (except first and last) touches the arc at its midpoint.
  • Otherwise the prior and successor curves are extended to simple intersection.
