````{py:method} decodeWithType(img, points) -> retval, decoded_info, decoded_type

Decodes barcode in image once it's found by the detect() method.     *
     * @param img grayscale or color (BGR) image containing bar code.
     * @param points vector of rotated rectangle vertices found by detect() method (or some other algorithm).
     * For N detected barcodes, the dimensions of this array should be [N][4].
     * Order of four points in vector<Point2f> is bottomLeft, topLeft, topRight, bottomRight.
     * @param decoded_info UTF8-encoded output vector of string or empty vector of string if the codes cannot be decoded.
     * @param decoded_type vector strings, specifies the type of these barcodes
     * @return true if at least one valid barcode have been found
