failed to convert the circle

[ZiluoLiu-LXKJ]

I tried to convert Canvas to SVG, but failed to convert circles. Circles do not appear in the new SVG.

Here is the API I wrote to implement the transformation:

`import {Context} from 'svgcanvas'
handle_saveSvg() {
let width = this.canvas.canvas.width
let height = this.canvas.canvas.height
console.log(width,height,"rect")
// let C2S = window.C2S
let ctx = new Context(width + 500, height + 500)
console.log(ctx, "ctx")
for (let pen of this.canvas.store.data.pens) {
console.log(pen, "pen")
if (pen.type) {
let line = pen
line.from = {}
line.to = {}
}
this.canvas.renderPenRaw(ctx, pen)
}
console.log(ctx, "ctx1")

  let mySerializedSVG = ctx.getSerializedSvg()
  console.log(mySerializedSVG, "svg")
  mySerializedSVG = mySerializedSVG.replace(
    "<defs/>",
    `<defs>

<style type="text/css"> @font-face { font-family: 'topology'; src: url('https://at.alicdn.com/t/font_1331132_h688rvffmbc.ttf') format('truetype'); } @font-face { font-family: 'ltee'; src: url('https://at.alicdn.com/t/font_2052340_ceohsubmal7.ttf') format('truetype'); } @font-face { font-family: 'ltdx'; src: url('https://at.alicdn.com/t/font_2073009_5ilnjxypv6l.ttf') format('truetype'); } @font-face { font-family: 'ticon'; src: url('https://at.alicdn.com/t/font_1331132_g7tv7fmj6c9.ttf') format('truetype'); } </style>

`
)
mySerializedSVG = mySerializedSVG.replace(/--le5le--/g, '&#x')

  const urlObject = window.URL || window
  const export_blob = new Blob([mySerializedSVG])
  const url = urlObject.createObjectURL(export_blob)

  const a = document.createElement('a')
  let name = sessionStorage.getItem("areaName")
  a.setAttribute('download', name + '.svg')
  a.setAttribute('href', url)
  const evt = document.createEvent('MouseEvents')
  evt.initEvent('click', true, true)
  a.dispatchEvent(evt)
}`
