MapProjectionDelegate

Definition of a map projection delegate.

Functions

cameraForCoordinateBounds

Convert to a camera options from a given LatLngBounds, padding, bearing and pitch values.

abstract fun cameraForCoordinateBounds(coordinateBounds: CoordinateBounds, padding: EdgeInsets, bearing: Double?, pitch: Double?): CameraOptions

cameraForCoordinates

Convert to a camera options from a given list of points, padding, bearing and pitch values.

abstract fun cameraForCoordinates(coordinates: List<Point>, padding: EdgeInsets, bearing: Double?, pitch: Double?): CameraOptions

cameraForGeometry

Convert to a camera options from a given geometry, padding, bearing and pitch values.

abstract fun cameraForGeometry(geometry: Geometry, padding: EdgeInsets, bearing: Double?, pitch: Double?): CameraOptions

coordinateBoundsForCamera

Convert to a LatLngBounds from a given camera options.

abstract fun coordinateBoundsForCamera(cameraOptions: CameraOptions): CoordinateBounds

coordinateBoundsZoomForCamera

Returns the coordinate bounds and zoom for a given camera.

Note that if the given camera shows the antimeridian, the returned wrapped bounds might not represent the minimum bounding box.

See also {@link #coordinateBoundsZoomForCameraUnwrapped}

abstract fun coordinateBoundsZoomForCamera(cameraOptions: CameraOptions): CoordinateBoundsZoom

coordinateBoundsZoomForCameraUnwrapped

Returns the unwrapped coordinate bounds and zoom for a given camera.

This method is particularly useful, if the camera shows the antimeridian.

abstract fun coordinateBoundsZoomForCameraUnwrapped(cameraOptions: CameraOptions): CoordinateBoundsZoom

coordinateForPixel

Calculate a geographical coordinate(i.e., longitude-latitude pair) that corresponds to a screen coordinate.

The screen coordinate is in MapOptions.size platform pixels relative to the top left of the map (not of the whole screen).

abstract fun coordinateForPixel(screenCoordinate: ScreenCoordinate): Point

coordinateForProjectedMeters

Calculate a longitude-latitude pair for a Spherical Mercator projected meters.

abstract fun coordinateForProjectedMeters(projectedMeters: ProjectedMeters): Point

coordinatesForPixels

Calculate geographical coordinates(i.e., longitude-latitude pair) that corresponds to screen coordinates.

The screen coordinates are in MapOptions.size platform pixels relative to the top left of the map (not of the whole screen).

abstract fun coordinatesForPixels(pixels: List<ScreenCoordinate>): List<Point>

equals

open operator override fun equals(other: Any?): Boolean

getMetersPerPixelAtLatitude

Calculate distance spanned by one pixel at the specified latitude at current zoom level.

abstract fun getMetersPerPixelAtLatitude(latitude: Double): Double

Calculate distance spanned by one pixel at the specified latitude and zoom level.

abstract fun getMetersPerPixelAtLatitude(latitude: Double, zoom: Double): Double

hashCode

open override fun hashCode(): Int

pixelForCoordinate

Calculate a screen coordinate that corresponds to a geographical coordinate (i.e., longitude-latitude pair).

The screen coordinate is in MapOptions.size platform pixels relative to the top left of the map (not of the whole screen).

abstract fun pixelForCoordinate(point: Point): ScreenCoordinate

pixelsForCoordinates

Calculate screen coordinates that corresponds to geographical coordinates (i.e., longitude-latitude pair).

The screen coordinates are in MapOptions.size platform pixels relative to the top left of the map (not of the whole screen).

abstract fun pixelsForCoordinates(coordinates: List<Point>): List<ScreenCoordinate>

project

Calculate a point on the map in Mercator Projection for a given coordinate at the specified zoom scale.

abstract fun project(point: Point, zoomScale: Double): MercatorCoordinate

projectedMetersForCoordinate

Calculate Spherical Mercator ProjectedMeters coordinates.

abstract fun projectedMetersForCoordinate(point: Point): ProjectedMeters

toString

open override fun toString(): String

unproject

Calculate a coordinate for a given point on the map in Mercator Projection.

abstract fun unproject(coordinate: MercatorCoordinate, zoomScale: Double): Point
