HarmonyOS 有没有同时支持富文本和字体大小自适应的组件？

import {TextInfo,TextLayout} from '@ohos/textlayoutbuilder';  
  
@Entry  
@Component  
struct textTest{  
  @State layout:TextLayout.Layout = new TextLayout.Layout();  
  @State strTest:string = "多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的多颜色的"  
  aboutToAppear() {  
  
    let textInfo = new TextInfo();  
    textInfo.setStart(2)  
    textInfo.setEnd(8)  
    textInfo.setFontColor('#ff0000')  
    textInfo.setFontSize("10fp")  
  
    let textInfo1 = new TextInfo();  
    textInfo1.setStart(10)  
    textInfo1.setEnd(12)  
    textInfo1.setFontColor('#ff00ff')  
    textInfo1.setFontSize("20fp")  
  
    this.layout  
      .setText(this.strTest)  
      .setSpecialTextInfo(textInfo)  
      .setSpecialTextInfo(textInfo1)  
      .setSingleLine(true)  
      .setEllipsize(TextOverflow.Ellipsis)  
  }  
  build() {  
    Column(){  
      Column() {  
        TextLayout({ model: this.layout })  
      }  
    }  
  }  
}
