translateRegionPoints

Callable

• translateRegionPoints(points: Point2D[], regionType: RegionType, delta: Point2D): Point2D[]

---

• Returns translated control points for a region without mutating the input.

  Center-based regions move only their center control point and preserve size or offset control points. Line-like and polygonal regions move every control point by the supplied delta.
