使用（Usage）

点击此处查看使用说明。

方式一： 如果过你的页面足够简单，只是一个简单的html静态页面或者是你不想引入太多的package,那么你可以下载watermark.min.js 并将其导入到 HTML文件中，这样你就可以使用watermark的这个全局对象来加载水印:

(Download index.js and include it in your HTML document, this will add a global object called watermark)

<script src="watermark.min.js"></script>
<script type="text/javascript">
      watermark.setWatermark(
         {
           w_texts: ['第一行水印', '第二行水印'],
         }
      )
</script>

方式二： 安装npm包导入到需要使用的项目中去：

(Alternatively you can use a JavaScript package manager to add it to your project)

npm install watermark-demo --save
   
// import
import watermark from 'watermark-demo'

导入后就可以调用下面的方法（After that you can call any of methods that are explained in the following）

watermark.setWaterMark()

使用时该方法时传入一个 options 配置对象, 配置对象主要有两个属性：w_texts、w_options。 w_texts：水印文案的数组集合可设置多行文案。 w_options：水印参数配置项，如字体大小、颜色等

You can use the watermark.setWaterMark method to set watermark. The value will automatically be escaped for you.

import watermark from 'watermark-demo'
// w_texts：水印文案数组
watermark.setWaterMark(
   {
      w_texts: ['第一行水印', '第二行水印']
   }
)

options 配置对象还有另一个属性 w_options水印参数配置：用于设置水印的具体参数如宽度，大小等，各参数说明见下表

If you need more options, like setting the width, you can add an object with options as the last parameter:

import watermark from 'watermark-demo'
watermark.setWaterMark(
  {
    w_texts: ['我是水印呀', '第二行水印'],
    w_options: {
      width: 200,
      height: 100,
      top: '0px',
      left: '0px',
      fontSize: '16',
      fontFamily: 'serif',
      fillStyle: 'rgba(200, 200, 200, 0.8)',
      textAlign: 'left', // 水印文本对齐方向
      rotateDeg: 20,
      zIndex: 999999
    }
   }
);
