使用（Usage）

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.umd.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 watermark.umd.min.js and include it in your HTML document, this will add a global object called watermark)

<script src="watermark.umd.min.js"></script>

<script type="text/javascript">
      watermark.setWaterMark(
         {
           w_texts: ['娃哈哈', '177****0000'],
         }
      )
</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-package --save

// import
import watermark from 'watermark-package'

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-package'
// w_texts：水印文案数组集合
watermark.setWaterMark(
   {
      w_texts: ['娃哈哈', '177****0000']
   }
)

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-package'
watermark.setWaterMark(
   {
      w_texts: ['娃哈哈', '177****0000'],
      w_options: {
        w_width: 240,
        w_height: 140,
        w_top: '0px',
        w_left: '0px',
        w_rotateDeg: 25,
        w_font: '1.2rem Vedana',
        w_color: '#666',
        w_opacity: '0.2',
        w_zIndex: '100000',
    }
   }
);

key	value	default value
w_width	A number that the width of the watermark block. (水印块宽度)	240
w_height	A number that the height of the watermark block. (水印块高度)	140
w_top	A string that the distance between the watermark mask layer and the top of the page. (水印遮罩层距离页面顶部的距离)	'0px'
w_left	A string that the distance between the watermark mask layer and the left of the page. (水印遮罩层距离页面左边的距离)	'0px'
w_rotateDeg	A string that specifies SameSite attribute that restricts cookie access based on the site context. (水印角度)	25
w_font	A string that the watermark font size, font style (水印的字体大小、字体风格)	'1.2rem Vedana'
w_color	A string that the watermark font color (水印字体颜色)	'#666'
w_opacity	A string that the watermark mask layer transparency (水印遮罩层透明度)	'0.2'
w_zIndex	A string that the zIndex of watermark mask (水印遮罩层层级)	10000
