编程式调用预览

Preview manually, no external display


<PicViewer :value="" v-show="false" ref="PicViewer"/>
<button @click="()=>{$refs.PicViewer.preview(6)}">preview</button>

二维码清晰度

<!-- 如果 value 的值比较小 而 size 的值比较大 会导致图片模糊 此时可以增大 scale 来解决 -->
<!-- scale 指二维码每个黑点占用的 px 数量 可选值为整数的二次方 如25 36 49 64 81 -->

<PicViewer :qrcodeProps="{
  scale: 900,
}"/>
