import PicViewer from 'pic-viewer'

  components: { PicViewer },
}
</script>

全局引入

npm add pic-viewer
import 'pic-viewer/dist/style.css'
import PicViewer from 'pic-viewer'

Vue.use(PicViewer, {
  // 全局配置
})

参数

参数名说明类型默认值
value图片源string, string[], object[]
pattern展示模式(waterfall, swipertable-cellstringundefined(即文档流)
viewerjs是否启用 viewerjsbooleantrue
viewerjsPropsviewerjs 的参数object{ zIndex: 5000, zoomRatio: 0.4 }
srcAt指定图片源所在的键(如果 value 为 object[] 类型)string
swiperPropsswiper 的参数object{ observer: true }
qrcode是否将 value 转换为二维码boolean, 'auto'false
qrcodePropsqrcode 的参数object{ margin: 0, errorCorrectionLevel: 'L', width: 444, height: 444 }

qrcode

如果将 qrcode 设为 'auto',pic-viewer 会自动判断是否需要转换(value 为 Base64 或 URL 时不会转换)


事件

名称说明参数
click点击图片后触发{ src, index }

插槽

名称说明
默认插槽自定义 img 标签
<!-- 示例 -->

<PicViewer>
  <template v-slot="{ src, index }">
    <img :src="src" alt="">
    <div>第{{ index + 1 }}张</div>
  </template>
</PicViewer>

方法

名称说明参数
preview手动预览数组下标,默认值为0

编程式调用预览

手动调用预览,不再外部展示


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

二维码清晰度

默认的图片 CSS 高度为148px(与 el-upload 保持一致),默认的二维码分辨率为444×444(三倍图),如果你增大了图片的 CSS 尺寸,将导致图片变模糊

解决: 将二维码分辨率设置为展示尺寸的三倍

<!-- 示例 -->

<template>
  <PicViewer
    :qrcodeProps="{
      width: 900,
      height: 900,
    }"
  />
</template>

<style scoped>
::v-deep .pic-viewer img {
  width: 300px;
  height: 300px;
}
</style>

获取 Swiper 实例

<template>
  <PicViewer
    ref="picViewer" pattern="swiper" :swiperProps="{
      on: {
        init: onSwiperInit,
      },
    }"
  />
</template>

<script>
import 'pic-viewer/dist/style.css'
import PicViewer from 'pic-viewer'

export default {
  components: { PicViewer },
  data() {
    return {
      swiper: null
    }
  },
  methods: {
    onSwiperInit() {
      this.$nextTick(() => {
        this.swiper = this.$refs.picViewer.swiper
      })
    }
  }
}
</script>
