.@Component
.struct LineTo {
.  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('100%')
.        .height('100%')
.        .backgroundColor('#ffff00')
.        .onReady(() =>{
.          this.context.beginPath()
.          this.context.moveTo(10, 10)
.          this.context.lineTo(280, 160)
.          this.context.stroke()
.        })

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

.
.  build() {
.    Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
.      Canvas(this.context)

.            this.context.beginPath()
.            this.context.moveTo(30, 30)
.            this.context.lineTo(110, 30)
.            this.context.lineTo(70, 90)
