如何在谷歌地图折线的中心设置折线标记？

Question

I am getting stuck when trying to set google map's polyline icon on the center of a line.

I am using a custom car icon which is not getting set properly on the polyline that I am drawing on the map. Please see the screenshot:

If I use the icon provided by the Google API by using path (path: google.maps.SymbolPath.FORWARD_CLOSED_ARROW) it shows on the center of the line.

Please see the below image:

How can we set the car icon on the middle of the line? Please check the sample code here .

For the car icon I am using the below code, is anything needed to be modified here?

var iconsetngs = {
            path: 'M25.395,0H17.636c-3.117,0-5.643,3.467-5.643,6.584v34.804c0,3.116,2.526,5.644,5.643,5.644h11.759' +

            fillColor: 'blue',

            strokeWeight: 0.4,
            offset: '50%'
        };
        var polyOptions = new google.maps.Polyline({
            path: path,
            strokeColor: '#0c0bbb',
            strokeWeight: 1.5,
            map: this.map,
            icons: [{
                icon: iconsetngs,
                repeat: '70px',
            }]
        });
        polyOptions.setMap(this.map);

You will need to modify the anchor point of the icon. In the fork of your example I have added anchor: new google.maps.Point(23, 0) , there are some details of the extra poperties available under Complex icons in the Google Maps documentation.
