Access Guide

In setRotation of TengineKit Api, there are two parameters ori and is_screen_rotate, which are the rotation angle and whether to follow the screen rotation. Whether the android:screenOrientation parameter in the Manifest follows the screen can be set. Not setting this parameter is to follow the screen rotation.

Process

1.Device preview

This part is to get data from Camera, as the SDK input.

2.Angle

We use the vertical screen as an angle of 0 degrees. Since the data collected by the Android camera always deviates by 90, it is necessary to set + (-90) when setting the ori parameter. The actual rotation angle of Android is to add a function through the sensor Calculate to get. For details, see the example in the Demo project.

3.Rendering

When rendering, it is rendered at an angle of 0°, which is the normal output that people see under normal circumstances. The Android part has Canvas and Opengl rendering. Using Opengl rendering can make your apk better.
