Struct maplibre::coords::Zoom

pub struct Zoom(f64);

Zoom is an exponential scale that defines the zoom of the camera on the map. We can derive the ZoomLevel from Zoom by using the [crate::coords::ZOOM_BOUNDS].

Implementations

impl Zoom

pub fn new(zoom: f64) -> Self

impl Zoom

pub fn from(zoom_level: ZoomLevel) -> Self

impl Zoom

pub fn scale_to_tile(&self, coords: &WorldTileCoords) -> f64

pub fn scale_to_zoom_level(&self, z: ZoomLevel) -> f64

pub fn scale_delta(&self, zoom: &Zoom) -> f64

pub fn zoom_level(&self, tile_size: f64) -> ZoomLevel

Adopted from Transform::coveringZoomLevel

This function calculates which ZoomLevel to show at this zoom.

The tile_size is the size of the tile like specified in the source definition, For example raster tiles can be 512px or 256px. If it is 256px, then 2x as many tiles are displayed. If the raster tile is 512px then exactly as many raster tiles like vector tiles would be displayed.
