AdditiveRectangleType

public protocol AdditiveRectangleType : RectangleType where Self.Vector : VectorAdditive

Protocol refining RectangleType with VectorAdditive extensions.

  • Returns a copy of this rectangle with its location offset by a given Vector amount.

    Declaration

    Swift

    func offsetBy(_ vector: Vector) -> Self

  • Returns a copy of this rectangle with its size increased by a given Vector amount.

    Declaration

    Swift

    func resizedBy(_ vector: Vector) -> Self
  • vertices Default implementation

    Returns a list of vertices corresponding to the extremes of this rectangle.

    Precondition

    Currently limited to vectors with < 64 scalars.

    Order of vertices in the result is not defined.
