For example, suppose a device has a naturally tall screen. The back-facing camera sensor is mounted in landscape. You are looking at the screen. If the top side of the camera sensor is aligned with the right edge of the screen in natural orientation, the value should be 90. If the top side of a front-facing camera sensor is aligned with the right of the screen, the value should be 270.
这段代码看不懂，谁能帮忙看看呢？
例如，假设一个设备有一个自然的高屏幕。背对着相机传感器安装在景观。你在看屏幕。如果摄像头传感器的顶部与屏幕的右边缘对齐，该值应为90。如果前端摄像头传感器的顶部与屏幕的右边对齐，值应该是270，大概意思是这个。。。
