HarmonyOS鸿蒙Next中如何给Text增加描边，好像只看到有shadow，outline外描边，没有文本描边的设置

@Entry
@Component
struct TextExample {
  private settings: RenderingContextSettings = new RenderingContextSettings(true)
  private context: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.settings)
  build() {
    Column() {
      Row() {
        Text("效果：")
          .fontSize(22)
          .fontColor(Color.Blue)
          .maxLines(1)
          .textOverflow({ overflow: TextOverflow.Ellipsis })
          .fontWeight(300)
        Canvas(this.context)
          .width('100%')
          .onReady(() => {
            this.context.font = 'bold 100px sans-serif';
            this.context.fillStyle = '#ff18f608';
            this.context.fillText("Canvas 绘制", 0, 250);
            this.context.font = 'bold 100px sans-serif';
            this.context.lineWidth = 1;
            this.context.strokeStyle = '#fffd0808';
            this.context.strokeText("Canvas 绘制", 0, 250);
          })
      }.width('100%').margin(5)
    }.width('100%')
  }
}
