Question

是否可以更改Google静态地图中的视角，例如在Google Maps API的情况下如何更改它 - 这里检查setTilt（）函数。 https://developers.google.com/maps/documentation/javascript/reference?hl=en

类似于Google静态地图的内容可以在url参数中传递。

Answer 1

静态地图API中无法使用。

有一项功能请求：Issue 3796: Enable access to 45° imagery through Static Maps API。

Answer 2

我做了一个解决方法，使用JavaScript + html2canvas获得倾斜的静态图像。检查https://stackoverflow.com/a/37750987/4537906
