    Methods

    • Casts this object to the specified type. Throws error on failure.

      Type Parameters

      • T1

        The target type of the cast.

      • T2

        The type of the object to cast.

      Parameters

      Returns T1

    • Determines whether the specified object is equal to the current object.

      Parameters

      • obj: any

        The object to compare with the current object.

      Returns boolean

      true if the specified object is equal to the current object; otherwise, false.

    • Indicates whether the current object is equal to another object of the same type.

      Parameters

      • other: Projection

        An object to compare with this object.

      Returns boolean

      true if the current object is equal to the other parameter; otherwise, false.

    • Serves as the default hash function.

      Returns number

      A hash code for the current object.

    • Returns a string that represents the current object.

      Returns string

      A string that represents the current object.

    • Casts this object to the specified type. Returns null on failure.

      Type Parameters

      • T1

        The target type of the cast.

      • T2

        The type of the object to cast.

      Parameters

      Returns null | T1

    • Determines whether the specified object instances are considered equal.

      Parameters

      • objA: any

        The first object to compare.

      • objB: any

        The second object to compare.

      Returns boolean

      true if the objects are considered equal; otherwise, false. If both objA and objB are null, the method returns true.

    Default capability

    • Initializes a new instance of the Spotfire.Dxp.Application.Visuals.Maps.Projection class.

      Parameters

      • identifier: string | String

        The projection identifier, either an EPSG code on the form "EPSG:1234" or "CustomIdentifierPrefix:ID" when referring to an imported coordinate reference system with id 'ID'. Any whitespace is removed from both ends of the string.

      Returns Projection

      2.0

    • Initializes a new instance of the Spotfire.Dxp.Application.Visuals.Maps.Projection class as a custom defined projection. This type of projection can be generated from imported GeoTIFF image files or from imported Shape files or they can be added by users.

      Parameters

      • identifier: string | String

        The projection identifier, either an EPSG code on the form "EPSG:1234" or "CustomIdentifierPrefix:ID" when referring to an imported coordinate reference system with id 'ID'. Any whitespace is removed from both ends of the string.

      • proj4Definition: string | String

        The projection PROJ4 definition.

      • displayName: string | String

        The projection display name.

      Returns Projection

      2.0

    None: Projection

    The non-geographic projection. Typically used for showing an arbitrary background image without geographic context.

    2.0

    WebMercator: Projection

    The "Web Mercator (auxiliary sphere)" coordinate reference system. See http://www.epsg-registry.org for reference.

    2.0

    Wgs84: Projection

    The "WGS 84" projection/coordinate reference system. See http://www.epsg-registry.org for reference.
