Best way to display a custom Google maps multiple

问题:

I have two images, one is like an icon and the other is the icon background, what is the best way to combine these two images and make a google marker v3 icon? They are not svg or paths, they are just two png images.

回答1:

Simplest way: Use an image editor to make a single image and use that as the icon for your custom marker.

If you can't or don't want to do that you can make a custom overlay (reference) that behaves like a marker and use it to overlay the two images in the correct order on the map.

You can use an excellent little library, RichMarker. Its documentation is here.

To make usage easier, you can even create your own custom marker class, something like this:

Ns.Marker = function(properties) {

    RichMarker.call(this, properties);

    this.setContent('<div class="three-images-marker">' +
            properties.NsImage ? '<div class="marker-image-1"><img src="'+properties.NsImage1+'"/></div>' : '' + 
            properties.NsFrameImage ? '<div class="marker-image-2"><img src="'+properties.NsImage2+'"/></div>' : '' +
        '</div>');
};

Ns.Marker.prototype = Object.create(RichMarker.prototype);


// and use it like this:
var gorgeousMarker = new Ns.Marker({
      position: yourMarkerLatlng,
      map: yourMap,
      NsImage: 'example.com/image.png',
      NsFrameImage: 'example.com/frame.png',
});

'Ns' is whatever namespace you use, if you do.

From here on it's CSS work, you can position the images as you like.
