Google Maps Api v3，自定义集群图标

Question

如何更改集群图标？我希望有相同的图标，但颜色不是蓝色。

Answer 1

您需要在初始化 MarkerClusterer 对象时使用样式参数 - 下面的代码显示了默认样式，因此如果您想重新着色其中一个图标，只需将相关 url 更改为您的图像...

//set style options for marker clusters (these are the default styles)
mcOptions = {styles: [{
height: 53,
url: "http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/images/m1.png",
width: 53
},
{
height: 56,
url: "https://github.com/googlemaps/js-marker-clusterer/tree/gh-pages/images/m2.png",
width: 56
},
{
height: 66,
url: "https://github.com/googlemaps/js-marker-clusterer/tree/gh-pages/images/m3.png",
width: 66
},
{
height: 78,
url: "https://github.com/googlemaps/js-marker-clusterer/tree/gh-pages/images/m4.png",
width: 78
},
{
height: 90,
url: "https://github.com/googlemaps/js-marker-clusterer/tree/gh-pages/images/m5.png",
width: 90
}]}

//init clusterer with your options
var mc = new MarkerClusterer(map, markers, mcOptions);

Google 更改了他的存储库。最新的集群仓库是：https://github.com/googlemaps/js-marker-clusterer 图片：https://github.com/googlemaps/js-marker-clusterer/tree/gh-pages/images

您也可以考虑从本地路径下载源代码并提供链接。这样您就可以更好地控制应用程序所需的资源。

local_path "/pucblic/"
mcOptions = {styles: [{
height: 53,
url: local_path+"m1.png",
width: 53
},
{
height: 56,
url: local_path+"m2.png",
width: 56
},
{
height: 66,
url: local_path+"m3.png",
width: 66
},
{
height: 78,
url: local_path+"m4.png",
width: 78
},
{
height: 90,
url:  local_path+"m5.png",
width: 90
}]}

一个快捷方式覆盖图像路径，如下所示：

MarkerClusterer.prototype.MARKER_CLUSTER_IMAGE_PATH_ = 
    "https://raw.githubusercontent.com/googlemaps/v3-utility-library/master/markerclustererplus/images/m";

这是原图

markerClusterOptions = {styles: [{
    height: 53,
    url: "https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m1.png",
    width: 53
    },
    {
    height: 56,
    url: "https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m2.png",
    width: 56
    },
    {
    height: 66,
    url: "https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m3.png",
    width: 66
    },
    {
    height: 78,
    url: "https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m4.png",
    width: 78
    },
    {
    height: 90,
    url: "https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m5.png,
    width: 90
    }]}
    markerCluster = new MarkerClusterer(map, markers,markerClusterOptions);
