Struct MapGrid

pub struct MapGrid { /* private fields */ }

A map grid is used to address tiles on a map.

The grid should be in projected coördinates. Use default() for Web Mercator.

Implementations

impl MapGrid

pub fn new(srid: i32, bbox: BBox<f64>) -> Self

Create a new map grid.

• srid Spatial reference ID.
• bbox Bounding box.

pub fn srid(&self) -> i32

Get the spatial reference ID.

pub fn bbox(&self) -> BBox<f64>

Get the bounding box of the grid.

pub fn tile_bbox(&self, tid: TileId) -> BBox<f64>

Get the bounding box of a tile ID.

pub fn tile_transform(&self, tid: TileId) -> Transform<f64>

Get the transform to coördinates in 0 to 1 range.
