导出PDF字体设置 ActiveReportsJS默认可以导出PDF、Excel、Html。但是在导出PDF的时候需要进行字体文件的配置，如果没有进行字体配置，那么导出PDF就会出现乱码

下面就来进行字体配置的具体讲解

**1、首先新建一个项目，项目名称叫做 "Viewer"

2、新建一个fonts文件，进行字体的配置 **

** 配置文件(这里我默认设置的字体是微软雅黑)**

`{ "path": "", "descriptors": [ { "name": "微软雅黑", "locals": [ "微软雅黑", "MicrosoftYaHei" ], "source": "fonts/SimHei.ttf" }, { "name": "微软雅黑 Light"
}, { "name": "等线" }, { "name": "等线 Light"

    },
    {
        "name": "宋体",
        "source": "fonts/SimHei.ttf"


    },
    {
        "name": "仿宋"
    },
    {
        "name": "新宋体"
    },
    {
        "name": "幼圆"
    },
    {
        "name": "楷体"
    },
    {
        "name": "隶书"
    },
    {
        "name": "黑体",
        "source": "fonts/SimHei.ttf"
    },
    {
        "name": "Arial"
    },
    {
        "name": "Arial Black"
    },
    {
        "name": "Comic Sans MS"
    },
    {
        "name": "Courier New"
    },
    {
        "name": "Geneva"
    },
    {
        "name": "Georgia"
    },
    {
        "name": "Helvetica"
    },
    {
        "name": "Impact"
    },
    {
        "name": "Lucida Console"
    },
    {
        "name": "Meiryo"
    },
    {
        "name": "Meiryo UI"
    },
    {
        "name": "MingLiU"
    },
    {
        "name": "MingLiU-ExtB"
    },
    {
        "name": "MS Gothic"
    },
    {
        "name": "MS Mincho"
    },
    {
        "name": "MS PGothic"
    },
    {
        "name": "MS PMincho"
    },
    {
        "name": "MS Song"
    },
    {
        "name": "MS UI Gothic"
    },
    {
        "name": "NSimSun"
    },
    {
        "name": "Osaka"
    },
    {
        "name": "PMingLiU"
    },
    {
        "name": "PMingLiU-ExtB"
    },
    {
        "name": "SimSun"
    },
    {
        "name": "SimSun-ExtB"
    },
    {
        "name": "Song"
    },
    {
        "name": "Tahoma"
    },
    {
        "name": "Times New Roman"
    },
    {
        "name": "Trebuchet MS"
    },
    {
        "name": "Verdana"
    },
    {
        "name": "Yu Gothic"
    }
]

}`

**3、打开项目中的index.html，引入该方法： **

viewer.registerFont("fonts/fontsConfig.json");

    }

</style>

<div id="viewer-host"></div>

<script>   

  const viewer = new ActiveReports.Viewer("#viewer-host", { language: "zh" });

  viewer.registerFont("fonts/fontsConfig.json"); //引入字体配置；

  viewer.open('reports/MonthSurvey.rdlx-json');

</script>

4、预览结果
