如何在xamarin android中旋转YuvImage

YuvImage yuvImage = // 获取YuvImage对象
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
yuvImage.compressToJpeg(new Rect(0, 0, yuvImage.getWidth(), yuvImage.getHeight()), 100, outputStream);
byte[] jpegData = outputStream.toByteArray();
Bitmap bitmap = BitmapFactory.decodeByteArray(jpegData, 0, jpegData.length);

Matrix matrix = new Matrix();
matrix.postRotate(angle); // 设置旋转角度，angle为旋转的角度
bitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);

ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
byte[] jpegData = outputStream.toByteArray();
YuvImage rotatedYuvImage = new YuvImage(jpegData, ImageFormat.NV21, bitmap.getWidth(), bitmap.getHeight(), null);
