HarmonyOS是否有将界面生成图片的方法

import {componentSnapshot} from '@kit.ArkUI' 
import { image } from '@kit.ImageKit'; 
@Entry 
@Component 
struct SnapshotExample { 
  @State pixmap: image.PixelMap | undefined = undefined 
  build() { 
    Column() { 
      Row() { 
        Image(this.pixmap).width(200).border({ color: Color.Black, width: 2 }).margin(5) 
        Column(){ 
          Image($r('app.media.app_icon')).autoResize(true).width(100).height(100).margin(5).id("root") 
          Text('测试').fontSize(20).fontWeight(FontWeight.Bold).fontColor(Color.Red) 
          Button('测试') 
        }.id('root') 
      } 
      Button("click to generate UI snapshot") 
        .onClick(() => { 
          componentSnapshot.get("root", (error: Error, pixmap: image.PixelMap) => { 
            if (error) { 
              console.log("error: " + JSON.stringify(error)) 
              return; 
            } 
            this.pixmap = pixmap 
          }) 
        }).margin(10) 
    } 
    .width('100%') 
    .height('100%') 
    .alignItems(HorizontalAlign.Center) 
  } 
}
