shiftRegionPoints

Callable

• shiftRegionPoints(points: Point2D[], regionType: RegionType, offsetX: number, offsetY: number): Point2D[]

---

• Translates a region's control points by the given offset.

  For center-based region types (POINT, RECTANGLE, ELLIPSE, and their annotation equivalents) only the first control point (the center) is shifted; size and shape points remain unchanged. For all other types every control point is shifted.

  Parameters

  • points: Point2D[]

    Control points of the region in image pixel coordinates.

  • regionType: RegionType

    The type of the region.

  • offsetX: number

    Horizontal translation in image pixels.

  • offsetY: number

    Vertical translation in image pixels.

  Returns Point2D[]

  A new array of shifted control points (original array is not mutated).
