    Detailed Description

    Member Function Documentation

    KmlViewpoint::KmlViewpoint(Esri::ArcGISRuntime::KmlViewpoint &&other)

    Move constructor from the other KmlViewpoint.

    KmlViewpoint::KmlViewpoint(const Esri::ArcGISRuntime::KmlViewpoint &other)

    Copy constructor from the other KmlViewpoint.

    KmlViewpoint::KmlViewpoint()

    Default constructor.

    Use this constructor to create a KML viewpoint for Qt. This is provided for convenience only and will construct an empty object.

    Esri::ArcGISRuntime::KmlViewpoint &KmlViewpoint::operator=(Esri::ArcGISRuntime::KmlViewpoint &&other)

    Move operator from other KmlViewpoint.

    Esri::ArcGISRuntime::KmlViewpoint &KmlViewpoint::operator=(const Esri::ArcGISRuntime::KmlViewpoint &other)

    Assignment operator from other KmlViewpoint.

    KmlViewpoint::~KmlViewpoint()

    Destructor.

    Esri::ArcGISRuntime::KmlAltitudeMode KmlViewpoint::altitudeMode() const

    Returns the KML viewpoint's altitude mode.

    Altitude mode indicates how the altitude values relate to the ground or sea level.

    [static] Esri::ArcGISRuntime::KmlViewpoint KmlViewpoint::createCameraViewpoint(const Esri::ArcGISRuntime::Point &cameraLocation, double heading, double pitch, double roll, Esri::ArcGISRuntime::KmlAltitudeMode altitudeMode)

    A static method that returns a KmlViewpoint from the provided camera location.

    • cameraLocation - The location of the camera.
    • heading - The heading value.
    • pitch - The pitch value.
    • roll - The roll value.
    • altitudeMode - Enumeration of the KML altitude modes.

    This function was introduced in Esri::ArcGISRuntime 100.6.

    [static] Esri::ArcGISRuntime::KmlViewpoint KmlViewpoint::createLookAtViewpoint(const Esri::ArcGISRuntime::Point &lookAtLocation, double heading, double pitch, double range, Esri::ArcGISRuntime::KmlAltitudeMode altitudeMode)

    A static method that creates a KmlViewpoint from the provided look at location.

    • lookAtLocation - The observed location.
    • heading - - The heading value.
    • pitch - The pitch value.
    • range - The range value.
    • altitudeMode - Enumeration of the KML altitude modes.

    This function was introduced in Esri::ArcGISRuntime 100.6.

    [static] Esri::ArcGISRuntime::KmlViewpoint KmlViewpoint::createWithViewpoint(const Esri::ArcGISRuntime::Viewpoint &viewpoint)

    A static method that creates a KML viewpoint from the provided viewpoint.

    The viewpoint must have a look at point, and optionally a camera.

    This function was introduced in Esri::ArcGISRuntime 100.6.

    double KmlViewpoint::heading() const

    Returns the KML viewpoint's heading.

    Heading is defined in terms of degrees from 0 (North) to 360, with 90 being East.

    bool KmlViewpoint::isEmpty() const

    Returns true if the object is empty, false otherwise.

    Esri::ArcGISRuntime::Point KmlViewpoint::location() const

    Returns the KML viewpoint's location. The location associated with this viewpoint, which can be an observed point (LookAt in KML) or the position of a Camera.

    double KmlViewpoint::pitch() const

    Returns the KML viewpoint's pitch.

    Pitch is the angle (in degrees) between the camera and the target location, the angle of the observer's view. Values can range from 0 (straight down) through 90 (looking horizontally) to 180 (straight up toward the sky).

    Pitch corresponds to tilt in the KML specification.

    Value ranges from 0 and 90 for LookAt viewpoints, 0 and 180 for Camera viewpoints.

    double KmlViewpoint::range() const

    Returns the KML viewpoint's range.

    Range indicates the distance between the camera and the LookAt viewpoint's target location.

    double KmlViewpoint::roll() const

    Returns the KML viewpoint's roll.

    Roll indicates rotation in degrees around the camera's Z axis.

    Esri::ArcGISRuntime::KmlViewpointType KmlViewpoint::type() const

    Returns the KML viewpoint's type (Camera or LookAt). A KmlViewpointType::Camera viewpoint defines the position of the camera directly. A KmlViewpointType::LookAt viewpoint defines the position of the camera relative to a point of interest. See Google's KML reference for details about KML viewpoint (abstractView) specification, including diagrams.
