Show raster image on the map

This tutorial provides step-by-step instructions on how to incorporate a raster image overlay onto the map.

NPM module
Basic JavaScript

Copy the following code, paste it into your favorite text editor, and save it as a .html file.

Install the npm package.
Include the CSS file.

If you have a bundler that can handle CSS, you can import the CSS or include it with a <link> in the head of the document via the CDN
Include the following code in your JavaScript file (Example: app.js).

Replace YOUR_MAPTILER_API_KEY_HERE with your own API key. Make sure to protect the key before publishing your map app!
The next is up to you. You can center your map wherever you desire (modifying the starting position) and set an appropriate zoom level (modifying the starting zoom) to match your users’ needs. Additionally, you can change the map’s look (by updating the source URL); choose from a range of visually appealing map styles from our extensive MapTiler standard maps, or create your own to truly differentiate your application.

Add event handler for map load event. You will add code to create an image source and image layer in this handler.
```
     map.on('load', function() {
        
     });
 
```

Create image source. Here you can get the example image aerial_wgs84.png


     map.on('load', function() {
         map.addSource("aerial-source", {
             "type": "image",
             "url": "img/aerial_wgs84.png",
             "coordinates": [
                 [4.639663696289062, 50.900867668253724],
                 [4.642066955566406, 50.900867668253724],
                 [4.642066955566406, 50.89935199434383],
                 [4.639663696289062, 50.89935199434383]
             ]
         });
     });

Add the image layer


     map.addLayer({
         "id": "overlay",
         "source": "aerial-source",
         "type": "raster",
         "paint": {
             "raster-opacity": 0.85
         }
     });
