Google Maps API:缩放时,SVG标记会相对于地图移动

您必须为符号定义锚点(对于符号,默认值为左上角,而图像的默认值为底部中心)

对于该特定符号,底部中心锚点的点将是近似的 258,381

底部中心原点计算说明(适用于inkscape).

假设您没有自己创建路径(符号),使用给定路径创建SVG文档:

使用inkscape打开此文档.

首先去File->document-properties->page确定文档高度(对我而言,它是1052.36px,我猜这是默认值)

然后单击符号将其选中,在菜单栏中您应该看到对象的属性:X,Y,W(宽度),(H)八.

对我来说现在是:
document-height: 1052.36
object-x: 130.909
object-y: 671.362
object-width: 254.155
object-height: 286.093

计算底部
的y:从文档高度减去object-y(1052-671 = 381)

计算中心的x:将对象宽度的一半加到对象x(131+(254/2)= 258)

所以锚是 new google.maps.Point(258,381)
