HarmonyOS ArkUI中是否可以给文字添加添加描边？

@Entry  
@Component  
struct Index {  
  //用来配置CanvasRenderingContext2D对象的参数，包括是否开启抗锯齿，true表明开启抗锯齿。  
  private settings: RenderingContextSettings = new RenderingContextSettings(true)  
  //用来创建CanvasRenderingContext2D对象，通过在canvas中调用CanvasRenderingContext2D对象来绘制。  
  private context: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.settings)  
  build() {  
    Column() {  
      Canvas(this.context)  
        .width('100%')  
        .height('100%')  
        .onReady(() => {  
          // 描边文本  
          this.context.font = '55px sans-serif';  
          this.context.strokeStyle = "#ffea0acb";  
          // 描边宽度  
          this.context.lineWidth = 1  
          this.context.strokeText("描边文本", 10, 300);  
          this.context.fillStyle = "black";  
          this.context.fillText("描边文本", 10, 300);  
        })  
    }  
    .width('100%')  
    .height('100%')  
    .padding({ left: 20 })  
  }  
}
