Question

这是我下面的代码，我选择一个图像来表示我的标记，图像太大了，有没有一种方法我可以调整我的图像也看起来更小，例如填充，imagesizeicon等

 function initialize() {
    var mapOptions = {
      zoom: 13,
      mapTypeId: google.maps.MapTypeId.ROADMAP,
      center: center
    };

    map = new google.maps.Map(document.getElementById('map_canvas'),
            mapOptions);

for (var i=0; i<a.length;i++)
{
if(i == 0) iconImage = "image1.jpg";
else if(i == 1)  iconImage = "image2.jpg";
    marker = new google.maps.Marker({
      map:map,
      draggable:true,
      animation: google.maps.Animation.DROP,
      position: a[i],
icon: iconImage,
  });

使用google.maps.icon对象指定图标而不是简单图像文件名。在那里你可以设置size，例如

marker = new google.maps.Marker({
    map:map,
    draggable:true,
    animation: google.maps.Animation.DROP,
    position: a[i],
    icon: {
        size: new google.maps.Size(width, height),
        scaledSize: new google.maps.Size(width, height),
        url: iconImage 
    },
});
