Struct geom::bounds::GPSBounds

pub struct GPSBounds {
    pub min_lon: f64,
    pub min_lat: f64,
    pub max_lon: f64,
    pub max_lat: f64,
}

Represents a rectangular boundary of LonLat points. After building one of these, LonLats can be transformed into Pt2Ds, treating the top-left of the boundary as (0, 0), and growing to the right and down (screen-drawing order, not Cartesian) in meters.

Fields

min_lon: f64

min_lat: f64

max_lon: f64

max_lat: f64

Implementations

impl GPSBounds

pub fn new() -> GPSBounds

A boundary including no points.

pub fn from(pts: Vec<LonLat>) -> GPSBounds

Create a boundary covering some points.

pub fn update(&mut self, pt: LonLat)

Update the boundary to include this point.

pub fn contains(&self, pt: LonLat) -> bool

True if the point is within the boundary.

pub fn get_max_world_pt(&self) -> Pt2D

The bottom-right corner of the boundary, in map-space.

pub fn to_bounds(&self) -> Bounds

Converts the boundary to map-space.

pub fn try_convert(&self, pts: &[LonLat]) -> Option<Vec<Pt2D>>

Convert all points to map-space, failing if any points are outside this boundary.

pub fn convert(&self, pts: &[LonLat]) -> Vec<Pt2D>

Convert all points to map-space. The points may be outside this boundary.

pub fn convert_back(&self, pts: &[Pt2D]) -> Vec<LonLat>

Convert map-space points back to LonLats. This is only valid if the GPSBounds used is the same as the one used to originally produce the Pt2Ds.

Trait Implementations

impl Clone for GPSBounds

fn clone(&self) -> GPSBounds

Returns a copy of the value.
