荣耀9x 使用wxml-to-canvas 1.0.1 生成的图片, 然后保存到本地，变形了

// 导入图片
const {wxml, style} = require('./demo.js')
Page({
  data: {
    src: ''
  },
  onLoad() {
    this.widget = this.selectComponent('.widget')
  },
  renderToCanvas() {
    const p1 = this.widget.renderToCanvas({ wxml, style })
    p1.then((res) => {
      this.container = res
      this.extraImage()
    })
  },
  extraImage() {
    const p2 = this.widget.canvasToTempFilePath()
    p2.then(res => {
wx.saveImageToPhotosAlbum({
  filePath: res.tempFilePath
  success(res) { }
})
      })
    }
  })
