推荐答案
地图。
var icon = "icon.png";
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'I am from Nepal.',
icon: icon,
});
如果您是一位photoshop极客，请将您的图标大小设为1px，减少不透明度以使其透明它会像魅力一样工作..玩得开心。
If you're a photoshop geek, set your icon size to 1px , reduce opacity to make it transparent.. It will work like a charm.. have a nice time..
