HarmonyOS 鸿蒙Next CanvasRenderingContext2D 绘制图形开启抗锯齿无用，图形依旧有锯齿如何解决。

绘制图形有锯齿很虚，只有把画布面积调大才不会有这个问题，但是不符合需求。哪位大神指导下如何解决抗锯齿问题，用其他的控件可以解决但是这里只想用 CanvasRenderingContext2D 来绘制所有的动画图形。

private settings: RenderingContextSettings = new RenderingContextSettings(true)
private context: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.settings)

// 绘制打勾
private drawSuccess(progress) {
  if (this.context.width === 0 || this.context.height === 0) {
    return
  }
  this.context.clearRect(0, 0, this.context.width, this.context.height);

  let centerX = this.context.width / 2;
  let centerY = this.context.height / 2;

  this.context.beginPath();
  //
  let radius = Math.min(centerX, centerY) - 5
  this.context.arc(centerX, centerY, radius, this.DEGREES_TO_RADIANS(-90),
    this.DEGREES_TO_RADIANS(360), false)
  this.context.strokeStyle = this.drawColor.toString();
  this.context.lineCap = ‘round’;
  this.context.lineWidth = 2
  this.context.stroke()
}
