HarmonyOS Canvas绘制圆角矩形

以下Demo供参考

@Entry
@Component struct test {
  private settings: RenderingContextSettings = new RenderingContextSettings(true)
  private context: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.settings)
  build() {
    Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
      Canvas(this.context)
        .width('90%')
        .height(300)
        .backgroundColor('#ff8f00')
        .onReady(() => {
          let radius = 10;
          //圆角弧度
          let x = 40;
          //左上角坐标x
          let y = 40;
          //左上角坐标y
          let width = 100;
          //矩形宽
          let height = 40;
          //矩形高
          this.context.beginPath();
          this.context.moveTo(x + radius, y);
          this.context.lineTo(x + width - radius, y);
          this.context.arcTo(x + width, y, x + width, y + radius, radius);
          this.context.lineTo(x + width, y + height - radius);
          this.context.arcTo(x + width, y + height, x + width - radius, y + height, radius);
          this.context.lineTo(x + radius, y + height);
          this.context.arcTo(x, y + height, x, y + height - radius, radius);
          this.context.lineTo(x, y + radius);
          this.context.arcTo(x, y, x + radius, y, radius);
          this.context.closePath();
          this.context.fillStyle = Color.Red
          this.context.fill();

        })
    }
    .width('100%')
    .height('100%')
  }
