Struct MapGrid 

pub struct MapGrid { /* private fields */ }

A grid used to address Pegs on a map

The grid has an associated spatial reference ID, which should use projected coordinates. 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 map grid

pub fn peg_bbox(&self, peg: Peg) -> BBox<f64>

Get the bounding box of a Peg

pub fn peg_transform(&self, peg: Peg) -> Transform<f64>

Get transform to Peg coördinates (range 0 to 1)

pub fn zxy_peg(&self, zoom: u32, x: f64, y: f64) -> Option<Peg>

Get Peg for a position (zoom, x, y)
