Maps.Area

Work with rectangular map areas (polygons) defined by two corners and an optional rotation.

This module provides a simplified interface for creating and using rectangular areas on a map. It wraps the internal polygon logic and exposes a clean public API.

Types

type alias Area =

Area

Represents a rectangular polygonal area on the map.

type alias AreaStyle =

AreaStyle

Represents the style of an area, including fill color and optional border.

Create

create : LatLng -> LatLng -> Area

Create a rectangular area from a top-left and bottom-right coordinate, with a rotation in degrees (clockwise, around the center of the rectangle).

import Maps.Area
import Maps.Geo exposing (latLng)


myArea =
    Maps.Area.create
        -- top-left
        (latLng 52.52 13.38)
        -- bottom-right
        (latLng 52.51 13.39)
        -- rotation in degrees
        30

withRotation : Float -> Area -> Area

Set the rotation of an area in degrees (clockwise, around the center of the rectangle).

import Maps.Area exposing (Area, withRotation)


myArea : Area
myArea =
    Maps.Area.create
        (Maps.Geo.latLng 52.52 13.38)
        (Maps.Geo.latLng 52.51 13.39)
        |> withRotation 45

withBorder :

{ width : Int

, color : String

}

-> Area

Set the border of an area with a specified width and color.

import Maps.Area exposing (Area, withBorder)


myArea : Area
myArea =
    Maps.Area.create
        (Maps.Geo.latLng 52.52 13.38)
        (Maps.Geo.latLng 52.51 13.39)
        |> withBorder { width = 2, color = "blue" }

withFill : String -> Area -> Area

Set the fill color of an area.

import Maps.Area exposing (Area, withFill)


myArea : Area
myArea =
    Maps.Area.create
        (Maps.Geo.latLng 52.52 13.38)
        (Maps.Geo.latLng 52.51 13.39)
        |> withFill "rgba(0, 128, 255, 0.4)"
