Full Screen Drag, Rotate, and Zoom——全屏、旋转和缩放

本文主要是介绍Full Screen Drag, Rotate, and Zoom——全屏、旋转和缩放，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Hold down Shift+Drag to rotate and zoom. Click the button in the top right corner to go full screen. Then do theShift+Drag thing again.

按住Shift键并拖动鼠标来旋转和缩放。单击右上角的按钮实现全屏，然后可以再次按住Shift键拖动鼠标来旋转和缩放地图。

If there is no button on the map, your browser does not support theFull Screen API.

如果地图上没有按钮，你的浏览器则不支持全屏控件的API。
