What is the construct interface `google.maps.Icon`
提问by ddinchev
The docs of Google Maps V3 JS APIdoes not seem to give the interface of the construct of google.maps.Icon. I found an example with MarkerImage, which seems to be deprecated now.
Google Maps V3 JS API的文档似乎没有给出google.maps.Icon. 我找到了一个带有 的示例MarkerImage，现在似乎已弃用。
So, what are the possible google.maps.Iconconstruct parameters and what is their order? How to define icon size, icon offset in sprite, icon anchor, etc?
那么，可能的google.maps.Icon构造参数是什么以及它们的顺序是什么？如何定义图标大小、精灵中的图标偏移量、图标锚点等？
Edit:
编辑：
How would I create an icon and assign it to a marker? Eg (not tested/does not work):
我将如何创建一个图标并将其分配给一个标记？例如（未测试/不起作用）：
var icon = new google.maps.Icon(path,
new google.maps.Size(32, 32), // size
new google.maps.Point(0, 32), // offset in sprite
null, // anchor
);
I do see the docs but I do not see example usage if that class!
我确实看到了文档，但我没有看到该课程的示例用法！

There is no constructor for the google.maps.Icon, it is an anonymous javascript object like MapOptions, MarkerOptions, PolygonOptions, etc.
google.maps.Icon 没有构造函数，它是一个匿名的 javascript 对象，如MapOptions、MarkerOptions、PolygonOptions等。
You use it like this:
你像这样使用它：
var icon = {
anchor: new Point(...),
url: "myurl"
// etc..
};
From Oliverin a comment: The point is: there is no such class (or function, for that matter) as google.maps.Icon. The API docs refer to it as google.maps.Icon object specification(here), as opposed to e.g. the InfoWindow class.
来自Oliver的评论：重点是：没有像 google.maps.Icon 这样的类（或函数，就此而言）。API 文档将其称为google.maps.Icon 对象规范（此处），而不是例如InfoWindow 类。

Hmm... Now, this answer is just wrong.
嗯......现在，这个答案是错误的。
You can't
你不能
var icon = new google.maps.Icon({
anchor: new Point(...),
url: "myurl"
// etc..
});
It's an object literal, which means that you can just use it like this:
它是一个对象字面量，这意味着您可以像这样使用它：
var icon = {
anchor: new Point(...),
url: "myurl"
// etc..
};
