    }

    if (width > 0 && height > 0)

      minnum = getParaToInt("minnum");

    }

    if (isParaExists("maxnum")) {

      maxnum = getParaToInt("maxnum");

    }

    if (minnum > 0 && maxnum > 0)

      captcha.setFontNum(minnum, maxnum);

    if (isParaExists("fontsize")) {

      fontsize = getParaToInt("fontsize");

    }

    if (fontsize > 0)

      captcha.setFontSize(fontsize, fontsize);

    //干扰线数量 默认0

    captcha.setLineNum(2);

    //噪点数量 默认50

    captcha.setArtifactNum(30);
