HarmonyOS 鸿蒙Next如何设置Image为圆形

可以参考demo

import display from '[@ohos](/user/ohos).display'


[@Entry](/user/Entry)
[@Component](/user/Component)
struct Page4 {
 [@State](/user/State) imgWidth:number=0

 // 2、获取相关信息，宽高
   aboutToAppear() {
     display.getAllDisplays((err, data) => {
       let screenWidth : number = data[0].width
       this.imgWidth=screenWidth * 0.136
     })
 }

 build() {
   Column({space:20}){
     Column(){
     }
     .width(this.imgWidth)
     .height(this.imgWidth)
     .clip(true)
     .borderRadius(this.imgWidth/2)
     .backgroundImage($r('app.media.app_icon'))
     .backgroundImagePosition(Alignment.Center)
     .border({width:1})
     .backgroundImageSize(ImageSize.Cover)

     Column(){
       Image($r('app.media.app_icon'))
         .width('100%')
         .height('100%')
     }
     .width(this.imgWidth)
     .height(this.imgWidth)
     .clip(true)
     .borderRadius(this.imgWidth/2)
   }

 }
}
