如何使用传单和Javascript在地图上添加图像 [英] How to add images on map using leaflet and Javascript

问题描述

我正在寻找一种使用Java脚本将图像添加到传单地图"的方法.

I am looking for a way to add images to a 'leaflet map' using Javascript.

我要做的是加载图像，调整图像的大小和位置，并将其附加到传单地图上.

What I want to do is to load image, adjust its size and position, and attach it to a leaflet map.

推荐答案

下面是一个基本演示，展示了如何使用imageOverlay.

Here's a basic demo showing how to add an image using imageOverlay.

您可以通过提供 imageBounds

// center of the map
var center = [-33.8650, 151.2094];

// Create the map
var map = L.map('map').setView(center, 5);

// Set up the OSM layer
L.tileLayer(
  'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
    attribution: 'Data © <a href="http://osm.org/copyright">OpenStreetMap</a>',
    maxZoom: 18
  }).addTo(map);

// add a marker in the given location
L.marker(center).addTo(map);
L.marker([-35.8650, 154.2094]).addTo(map);

var imageUrl = 'https://upload.wikimedia.org/wikipedia/commons/thumb/7/7c/Sydney_Opera_House_-_Dec_2008.jpg/1024px-Sydney_Opera_House_-_Dec_2008.jpg',
imageBounds = [center, [-35.8650, 154.2094]];

L.imageOverlay(imageUrl, imageBounds).addTo(map);

html,
body {
  height: 100%;
}
#map {
  height: 100%;
}

<script src="https://unpkg.com/leaflet@1.0.2/dist/leaflet.js"></script>
<link rel="stylesheet" type="text/css" href="https://unpkg.com/leaflet@1.0.2/dist/leaflet.css">

<div id="map"></div>
