如何更改带有集群的 tomtom map API 的标记图标?以下是我的代码。我是这个 API 的新手。并且还帮我更改集群图标
var addressPoints = [
[40.191891, -85.401695, '<b style="color:red;">Townsville</b>'],
[33.830517, -116.545601, '<b style="color:red;">Townsville</b>'],
[34.496212, -93.057220, '<b style="color:red;">Townsville</b>'],
[34.521530, -93.042267, '<b style="color:red;">Townsville</b>'],
[37.541290, -77.434769, '<b style="color:red;">Townsville</b>'],
[32.698437, -114.650398, '<b style="color:red;">Townsville</b>'],
[37.063969, -111.236816, '<b style="color:red;">Townsville</b>'],
[33.580944, -112.237068, '<b style="color:red;">Townsville</b>']
];
// Creating the map
var map = tomtom.map('map', {
key: 'AVjNSUnrzh6XFxaTHO79YVHFw0H0KfyA',
basePath: 'sdk'
}).setView([40.191891, -85.401695], 5);
//
var markerOptions = {
icon: tomtom.L.icon({
iconUrl: 'https://eyeonjewels.com/includes/images/retailer-large-icon.png',
iconSize: [50, 64],
})
};
// Placing markers
var markers = tomtom.L.markerClusterGroup();
addressPoints.forEach(function (point) {
var title = point[2];
marker = tomtom.L.marker(new tomtom.L.LatLng(point[0], point[1]), { title: title });
marker.bindPopup(title);
markers.addLayer(marker);
});
map.addLayer(markers);
请帮我更改标记图标。
