getRotationDegrees
abstract fun getRotationDegrees(): Int
Returns the rotation needed to transform the image to the correct orientation.
This is a clockwise rotation in degrees that needs to be applied to the image buffer. Note that for images that are in android.graphics.ImageFormat#JPEG this value will match the rotation defined in the EXIF.
The target rotation is set at the time the image capture was requested.
The correct orientation of the image is dependent upon the producer of the image. For example, if the ImageProxy that contains this instance of ImageInfo is produced by an ImageCapture, then the rotation will be determined by ImageCapture#setTargetRotation(int) or ImageCapture.Builder#setTargetRotation(int).
