Interface LookAtParams

If specified, zoomLevel and distance parameters are ignored and lookAt calculates best zoomLevel to fit given bounds.

• if bounds is {@link @here/harp-geoutils#GeoBox}, then lookAt use LookAtParams.target or bounds.target and ensure whole box is visible

• if bounds is {@link @here/harp-geoutils#GeoPolygon}, then lookAt use bounds.getCentroid() and ensure whole polygon is visible

• if bounds is {@link @here/harp-geoutils#GeoBoxExtentLike}, then lookAt will use LookAtParams.target or current MapView.target and ensure whole extents are visible

• if bounds is GeoCoordLike[], then lookAt will use LookAtParams.target or calculated target as center of world box covering given points and ensure all points are visible

Note in sphere projection some points are not visible if you specify bounds that span more than 180 degrees in any direction.

see

{@link (MapView.lookAt:WITH_PARAMS)} for details on how bounds interact with target parameter

default

zoomLevel defaults will be used if not set.

default

0 in MapView.constructor context.

default

MapView.heading in {@link (MapView.lookAt:WITH_PARAMS)} context.

note

If the given point is not on the ground (altitude != 0) MapView will do a raycasting internally to find a target on the ground.

As a consequence MapView.target and MapView.zoomLevel will not match the values that were passed into the {@link (MapView.lookAt:WITH_PARAMS)} method.

default

new GeoCoordinates(25, 0) in MapView.constructor context.

default

MapView.target in {@link (MapView.lookAt:WITH_PARAMS)} context.

default

0 in MapView.constructor context.

default

MapView.tilt in {@link (MapView.lookAt:WITH_PARAMS)} context.

note

Maximum supported tilt is 89°

note

Takes precedence over distance.

default

5 in MapView.constructor context.

default

MapView.zoomLevel in {@link (MapView.lookAt:WITH_PARAMS)} context.
