    fs::write(file_with_wm, text_with_wm).unwrap();
    println!("text with watermark saved in file <{}>", file_with_wm);

    // read text and extract the watermark
    let text_with_wm = fs::read_to_string(file_with_wm).unwrap();

    // extract
    let wm_extract = text_blind_watermark.extract(text_with_wm.as_str());

    println!("watermark extracted：{}", String::from_utf8_lossy(wm_extract.as_slice()))
}

It does not display well in IDE. Use other text editor or text viewer.
