Type Alias ProjectionObject

Type Declaration

• Readonly_scale: number

  Current scale

• Readonly_translate: readonly [number, number]

  Current translate [tx, ty]

• Readonly_raw: (lambda: number, phi: number) => readonly [number, number]

  Internal 2D raw projection (radians → unit coordinates)

• withScale: function

  • withScale(scale: number): ProjectionObject

    Return a new projection with the given scale

    Parameters

    • scale: number

    Returns ProjectionObject

• withTranslate: function

  • withTranslate(translate: readonly [number, number]): ProjectionObject

    Return a new projection with the given translate [tx, ty]

    Parameters

    • translate: readonly [number, number]

    Returns ProjectionObject

• fitSize: function

  • fitSize(size: readonly [number, number], object: GeoObject): ProjectionObject

    Auto-fit the projection so the given GeoObject fills [0,0]→[w,h]. D3-geo fitSize parity. Pass { type: 'Sphere' } for natural proportions.

    Parameters

    • size: readonly [number, number]
    • object: GeoObject

    Returns ProjectionObject

• fitExtent: function

  • fitExtent(extent: GeoBBox, object: GeoObject): ProjectionObject

    Auto-fit into an arbitrary pixel extent [[x0,y0],[x1,y1]]. D3-geo fitExtent parity.

    Parameters

    • extent: GeoBBox
    • object: GeoObject

    Returns ProjectionObject
