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
public func hash(into hasher: inout Hasher)

Hashes the essential components of this value by passing them to the given hasher.

Parameters
hasher
Hasher

Hasher to use when combining the components of this instance.

Properties
var speedRangeToStyleZoomSequence

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

var styleZoomSpeedRangesAnimationDuration

Duration of smooth scaling in the guidance mode when the speed changes and there are no maneuvers ahead/behind at a sufficiently close distance or on low-value roads.

var zoomInBeforeManeuverAnimationDuration

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.

var zoomOutAfterManeuverAnimationDuration

Duration of smooth zoom level decrease after passing the maneuver.

var minSpeedToConsiderInZoomInBeforeManeuverAnimation

Minimum speed in m/s at which the duration of smooth zoom level change is calculated based on not only the proximity to the maneuver, but also the current speed. It must be at least 0.1 m/s, values less than this are ignored.

var zoomInBeforeManeuverAnimationAcceleration

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

var distanceGapToManeuver

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.

var minAnimationDuration

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.
