Google Map Custom Marker With Css Rounded Corner

November 29, 2022 Post a Comment

I have managed to use and apply my own marker on google map as below. var marker = new google.maps.Marker({ position: point,

Solution 1:

As of version 3.17, the google.maps.Marker objects exists in the markerLayer pane which is just a fancy name for a div.

To get a reference to the markerLayer you need to create an OverlayView Object. Now, this object is a bit abstract. You need to implement a draw function for it to work. For example, open the basic example in a new tab and paste this to the console

var overlay = new google.maps.OverlayView();
overlay.draw=function() {};

overlay.setMap(map);

overlay.getPanes();

it returns:

{
    floatPane: div
    floatShadow: div
    mapPane: div
    markerLayer: div
    overlayImage: div
    overlayLayer: div
    overlayMouseTarget: div
    overlayShadow: div
}

Thay markerLayer is a div which contains the markers. If I create your marker using a given icon image,

var marker = new google.maps.Marker({
                position: map.getCenter(),
                map: map,                          
                icon: 'http://ruralshores.com/assets/marker-icon.png',
                optimized:false
             });

My markerLayer will be:

enter image description here

Where the selected div (the one with z-index 103) is the markerLayer.

If you wanted to access the markerLayer programatically, you could add a "markerLayer" class to it after getting its reference with the getPanes method. I guess that every image inside the markerLayer is a marker, so you could style it at will.

TL/DR : you can style it, provided you went through all the trouble of finding the DOM reference to your marker.

Edit: I made a bl.ocks for you to check

Solution 2:

When you know the url of the image used for the marker you know how to access it via CSS: use a attribute-selector.

Let's create a circle-marker based on your avatar enter image description here with a 1px black border:

Marker-setup:

icon:{
       url: 'https://www.gravatar.com/avatar/0a9745ea7ac5c90d7acadb02ab1020cd?s=32&d=identicon&r=PG&f=1',
       //the size of the image is 32x32, 
       //when you want to add a border you must add 2*borderWidth to the size
       size:new google.maps.Size(34,34)},
       //define the shape
       shape:{coords:[17,17,18],type:'circle'},
       //set optimized to false otherwise the marker  will be rendered via canvas 
       //and is not accessible via CSS
       optimized:false
     }

the CSS:

  img[src="https://www.gravatar.com/avatar/0a9745ea7ac5c90d7acadb02ab1020cd?s=32&d=identicon&r=PG&f=1"]{
    border-radius:16px;
    border:1px solid #000 !important;
  }

....done.

When you use a shadow use a larger size(depending on the size of the shadow ):

Solution 3:

Hello i try all this answers but no one work as i wanna Try this first Create a div contains the image (MarkerImage) and add CSS

   var map;

    function initialize() {
        var mapOptions = {
            zoom: 9,
            center: new google.maps.LatLng(40.6, -74)
        };
      map = new google.maps.Map(document.getElementById('map-canvas'),    mapOptions);

     // I create 3 markers using http://ruralshores.com/assets/marker-icon.png as icon
     var myIcon='http://ruralshores.com/assets/marker-icon.png';
     var marker1 = new google.maps.Marker({ position: {lat:40.8, lng:-74}, map: map, icon: myIcon, optimized:false });
     var marker2 = new google.maps.Marker({ position: {lat:40.6, lng:-74.5}, map: map, icon: myIcon , optimized:false });
     var marker3 = new google.maps.Marker({ position: {lat:40.5, lng:-74.3}, map: map, icon: myIcon , optimized:false });

     // I create an OverlayView, and set it to add the "markerLayer" class to the markerLayer DIV
     var myoverlay = new google.maps.OverlayView();
     myoverlay.draw = function () {
         this.getPanes().markerLayer.id='markerLayer';
     };
     myoverlay.setMap(map);

}


google.maps.event.addDomListener(window, 'load', initialize);

and now add somme CSS

#markerLayer img {
        border: 2px solid red !important;
        width: 85% !important;
        height: 90% !important;
        border-radius: 5px;
      }

Solution 4:

as mentioned above ,I used OverlayView

var AvatarMarker = function(latlng,avatarUrl,map,id){
      this.latlng = latlng;
      this.avatarUrl = avatarUrl;
      this.setMap(map);
      this.id= id;
    };
  AvatarMarker.prototype = new google.maps.OverlayView();
  AvatarMarker.prototype.onAdd= function(){
    var img = document.createElement("img"),me=this;
    img.style.width="30px";
    img.style.height="30px";
    img.style.position="absolute";
    img.style.webkitBorderRadius="50%";
    img.style.borderRadius="50%";
    img.style.zIndex="999";
    img.src=me.avatarUrl;
    this.getPanes().overlayMouseTarget.appendChild(img);
    me.img= img;
    img.onclick = function(){
      google.maps.event.trigger(me,"click",{id:me.id});
    }
  };
  AvatarMarker.prototype.draw = function(){
    this.setLatLng(this.latlng);
  }
  AvatarMarker.prototype.onRemove = function(){
    this.img.parentNode.removeChild(this.img);
    this.img =  null;
  }
  AvatarMarker.prototype.setLatLng = function(latlng){
    if(!this.getProjection()) return ;
    var overlayProjection = this.getProjection(),
      xy=overlayProjection.fromLatLngToDivPixel(latlng);
    this.img && (this.img.style.left=(xy.x-15)+'px');
    this.img && (this.img.style.top=(xy.y-15)+'px');
    google.maps.event.trigger(this,"draw");
  }
  AvatarMarker.prototype.getLatLng = function(){return this.latlng;}

Try this DEMO written in SCSS (Sass)
