Struct Projection 

pub struct Projection { /* private fields */ }

A configured map projection ready for forward and inverse transformations.

Implementations

impl Projection

pub fn new(params: ProjectionParams) -> Result<Self>

Build a Projection from the given parameters.

pub fn forward(&self, lon_deg: f64, lat_deg: f64) -> Result<(f64, f64)>

Forward projection: geographic (lon, lat) degrees → projected (x, y) meters.

pub fn inverse(&self, x: f64, y: f64) -> Result<(f64, f64)>

Inverse projection: projected (x, y) meters → geographic (lon, lat) degrees.

pub fn params(&self) -> &ProjectionParams

Return a reference to the projection parameters.

pub fn name(&self) -> &str

Return the name of the projection.

Trait Implementations

impl Clone for Projection

fn clone(&self) -> Self

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CoordTransform for Projection

fn transform_fwd(&self, point: Point2D) -> Result<Point2D>

Transform a single point forward.

fn transform_inv(&self, point: Point2D) -> Result<Point2D>

Transform a single point inverse.

fn transform_fwd_many(&self, points: &mut [Point2D]) -> Vec<Result<()>>

Transform a slice of points forward in-place.

fn transform_inv_many(&self, points: &mut [Point2D]) -> Vec<Result<()>>
