### Initialize and Preview PPTX with pptx-preview

Source: https://www.npmjs.com/package/pptx-preview/v/0.0.9?activeTab=versions

Import the init function from pptx-preview to create a previewer instance. Then, fetch the PPTX file as an ArrayBuffer and pass it to the preview method.

```javascript
import {init} from 'pptx-preview'

//调用库的init方法生成一个预览器
let pptxPrviewer = init(document.getElementById('pptx-wrapper'), {
    width: 960,
    height: 540
})

//获取文件或者读取文件，获取文件的 ArrayBuffer格式数据，传给组件进行预览
fetch('test.pptx').then(response=>{
    return response.arrayBuffer()
}).then(res =>{
    //调用预览器的preview方法
    pptxPrviewer.preview(res)
})
```
