基于Zxing库实现竖屏二维码扫码

是不是少了一段代码？ 我运行之后报错。 我在DecodeHandler中的decode中PlanarYUVLuminanceSource source定义之前添加如下代码后运行正常。

byte[] rotatedData = new byte[data.length];
        for (int y = 0; y < height; y++) {
            for (int x = 0; x < width; x++) {
                rotatedData[x * height + height - y - 1] = data[x + y * width];
            }
        }
        int tmp = width; // Here we are swapping, that's the difference to #11
        width = height;
        height = tmp;
        data = rotatedData;
