鸿蒙项目中如何启用硬件加速

@Component

struct AcceleratedCanvas {

  private settings: RenderingContextSettings = new RenderingContextSettings(true) // 开启硬件加速


  build() {

    Column() {

      Canvas(this.onCanvasReady)

        .width('100%')

        .height('300vp')

    }

  }


  onCanvasReady(ctx: CanvasRenderingContext2D) {

    // 使用硬件加速的2D渲染上下文

    ctx.fillStyle = '#ff0000'

    ctx.fillRect(0, 0, 100, 100)

  }

}

@State scale: number = 1


build() {

  Button('Click')

    .scale({ x: this.scale, y: this.scale })

    .onClick(() => {

      animateTo({

        duration: 1000,

        curve: Curve.Spring // 使用弹簧曲线，GPU加速

      }, () => {

        this.scale = 2

      })

    })

}
