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.

pub fn get_rectangle(&self) -> Vec<LonLat>

Returns points in order covering this boundary.

Trait Implementations
