Ellipse interface. An ellipse is a Shape that represents a general ellipse in the 2D space.

The ellipse is defined by:

An ellipse cannot be instantiated directly. It must be instantiated using createEllipse.

Overview

Accessors

a

  • get a(): number
  • set a(value: number): void
  • The length of the semi major axis of this ellipse, in meters.

    Returns number

  • The length of the semi major axis of this ellipse, in meters.

    Parameters

    • value: number

    Returns any

b

  • get b(): number
  • set b(value: number): void
  • The length of the semi minor axis of this ellipse, in meters.

    Returns number

  • The length of the semi minor axis of this ellipse, in meters.

    Parameters

    • value: number

    Returns any

bounds

center

coordinateType

  • The coordinate type this shape. This property is read only. An Error will be thrown when trying to assign to this property.

    Returns CoordinateType

focusPoint

  • get focusPoint(): Point

reference

  • The spatial reference of this shape. This property is read only. An Error will be thrown when trying to assign to this property.

    Returns CoordinateReference | null

rotationAzimuth

  • get rotationAzimuth(): number
  • set rotationAzimuth(value: number): void
  • The rotation angle of the semi major axis of this ellipse. The angle is measured in degrees from 12 o'clock (north), positive clockwise.

    The value is normalized to the range -180° .. 180°.

    Returns number

  • The rotation angle of the semi major axis of this ellipse. The angle is measured in degrees from 12 o'clock (north), positive clockwise.

    The value is normalized to the range -180° .. 180°.

    Parameters

    • value: number

    Returns any

type

Methods

contains2D

  • Determines whether a given point is inside this shape. This method checks containment only in two dimensions: on the (x,y)-axis or the (lon,lat)-axis (depending on the spatial reference of the shape).

    throws

    InvalidReferenceError when passing a Point with another spatial reference

    deprecated

    Please use contains2DPoint instead.

    Parameters

    • x: Point | number | Bounds

      The point for which containment must be checked. If a 3D point is passed to this function, it will be treated as a 2D point: the z coordinate (height) will be ignored. The reference of this point must be the same reference as this Shape

    • Optional y: number

    Returns boolean

    true when the given point is contained in this shape

Abstract contains2DCoordinates

  • (x: number, y: number): boolean
  • Determines whether the given point is inside this shape. This method checks containment only in two dimensions: on the (x,y)-axis or the (lon,lat)-axis (depending on the spatial reference of the shape).

    throws

    InvalidReferenceError when passing a Point with another spatial reference

    Parameters

    • x: number

      The x coordinate of the point for which containment must be checked

    • y: number

      The y coordinate of the point for which containment must be checked

    Returns boolean

    true when the given point is contained in this shape

contains2DPoint

  • (point: Point): boolean
  • Determines whether the given point is inside this shape. This method checks containment only in two dimensions: on the (x,y)-axis or the (lon,lat)-axis (depending on the spatial reference of the shape).

    throws

    InvalidReferenceError when passing a Point with another spatial reference

    Parameters

    • point: Point

      The point for which containment must be checked.

    Returns boolean

    true when the given point is contained in this shape

Abstract copy

equals

  • (ellipse: Shape): boolean

Abstract interpolate

  • (fraction: number): Point
  • Get a point on the ellipse relative to the major axis.

    The parameter is [0, 1] clockwise, relative to the rotation angle:

    • 0.0 and 1.0 are the same point on the major axis, "on top" of the ellipse
    • 0.25 is a point on the minor axis, "right" of the ellipse
    • 0.5 is a point on the major axis, opposite of the point at 0.0
    • 0.75 is a point on the minor axis, opposite of the point at 0.25

    Parameters

    • fraction: number

      A factor in [0, 1], relative to the ellipse's rotation.

    Returns Point

    The computed point

move2DToCoordinates

  • (x: number, y: number): void
  • Translates this ellipse so that its center point ends up at the specified position.

    Parameters

    • x: number

      x coordinate value

    • y: number

      y coordinate value

    Returns void

move2DToPoint

  • Translates this shape so that its center point ends up at the specified position.

    throws

    InvalidReferenceError when the reference of the Point parameter does not correspond with the reference of this Ellipse.

    Parameters

    Returns void

toString

  • (): string

translate2D

  • (x: number, y: number): void
