getRegionSelectionSegments

Callable

• getRegionSelectionSegments(region: RegionStore, points: Point2D[]): LineSegment2D[]

---

• Converts region selection points into line segments for hit testing.

  Compass annotations expose two segments from the shared origin, closed polygonal/simple-shape regions close their path, and open paths remain open.

  Parameters

  • region: RegionStore

    Region that owns the sampled points.

  • points: Point2D[]

    Selection points produced for the region.

  Returns LineSegment2D[]

  Line segments used to test intersection with a selection rectangle.
