条形码旋转 90 度的图像

我的代码:

    private static string GetBarcode(Bitmap btBitmap)
    {
        IBarcodeReader reader = new BarcodeReader
        {
            AutoRotate = true,
            TryInverted = true,
            Options =
            {
                PossibleFormats = new List<BarcodeFormat> { BarcodeFormat.CODE_39 },
                TryHarder = true,
                ReturnCodabarStartEnd = true,
                PureBarcode = false
            }
        };

        return   reader.DecodeMultiple(btBitmap)?.ToString(); 
    }

返回一个空值,但如果你旋转 90 度,一切都读得很好。怎么了?
