Setup ​

Plugin usage ​

This component is part of the Layers plugin. If not installed globally, you need to import and use the plugin in your main.ts or use the explicit component import (see section below).

Import and use the Layers plugin
ts
import { createApp } from "vue";
import App from "./App.vue";

import {

  Map,
  Layers,
  Sources,
} from "vue3-openlayers";

const app = createApp(App);
// ...
app.use(Layers); 
// ...

Explicit import ​

If you don't want to install a plugin, you can import the component explicitly. It's available as a child of the named export Layers.

NOTE

The following documentation refers to the plugin usage. Please make sure to adopt the component names, when you decided to use explicit component imports (e. g. <ol-map> becomes <Map.OlMap> etc.).

Example below shows how to use ol-image-layer component together with ol-source-image-static to render custom image on the map. The map view is configured with a custom projection that translates image coordinates directly into map coordinates.

vue
<template>
  <ol-map
    :loadTilesWhileAnimating="true"
    :loadTilesWhileInteracting="true"
    style="height: 400px"
  >
    <ol-view
      ref="view"
      :center="center"
      :zoom="zoom"
      :projection="projection"
    />
    <ol-zoom-control />
    <ol-attribution-control />
    <ol-image-layer id="xkcd">
      <ol-source-image-static
        :url="imgUrl"
        :imageSize="size"
        :imageExtent="extent"
        :projection="projection"
        :attributions="imgCopyright"
      ></ol-source-image-static>
    </ol-image-layer>
  </ol-map>
</template>

<script setup>
import { ref, reactive } from "vue";

const zoom = ref(2);
const size = ref([1024, 968]);
const center = ref([size.value[0] / 2, size.value[1] / 2]);
const extent = ref([0, 0, ...size.value]);
const projection = reactive({
  code: "xkcd-image",
  units: "pixels",
  extent: extent,
});
const imgUrl = ref("https://imgs.xkcd.com/comics/online_communities.png");
const imgCopyright = ref('© <a href="http://xkcd.com/license.html">xkcd</a>');
</script>
