ZoomFollowSettings

Interface that allows you to control the map zoom settings during guidance.

Extends: Hashable
public static func == (lhs: ZoomFollowSettings, rhs: ZoomFollowSettings) -> Bool

Returns a Boolean value indicating whether two values are equal.

Methods
Properties

Sequence of speed intervals and corresponding scales. Used to automatically change the scale in the navigator depending on the speed.

Duration of the smooth change of scale in the guidance mode when there are no maneuvers ahead/behind at a sufficiently close distance, or on low-value roads.

Duration of the smooth zoom level increase when approaching a maneuver. Used only if the speed is lower than in get_min_speed_to_consider_in_zoom_in_before_maneuver_animation.

Duration of smooth zoom level decrease after passing the maneuver.

Minimum speed in m/s, at which the duration of the smooth zoom level change is calculated taking into account not only the proximity to the maneuver, but also the current speed. Must be at least 0.1 m/s, values less than that will be ignored.

Acceleration coefficient of the zoom level increase animation when approaching the maneuver. Must be at least 1, values less than that will be ignored.

Distance to the maneuver, at reaching which the animation of the smooth zoom level increase must be completed, so that during the maneuver the zoom does not change. For example, if the maneuver is 300 m, then the animation with the smooth zoom level increase must be completed 50 m before the maneuver. Must be at least 1 m, values less than that will be ignored.

Minimum Animation Time. Used to prevent sudden changes in the zoom level during the animation. Must be at least 200, values less than that will be ignored.
