scale method

  1. @override
LineSegment scale(
  1. num factor
)
override

Scales the shape uniformly by the given factor originating from centroid.

Implementation

@override
LineSegment scale(num factor) {
  final c = centroid;
  Point<num> scalePoint(Point<num> p) => Point(
    x: c.x + (p.x - c.x) * factor,
    y: c.y + (p.y - c.y) * factor
  );
  return LineSegment(p1: scalePoint(p1), p2: scalePoint(p2));
}
