HarmonyOS 使用项目的资源图片生成ImageBitmap无法在Cavans中显示

可以加载出来的，其图片加载路径的起点为当前Module的ets文件夹，注意这一点即可。

@Entry
@Component
struct ImageExample {
  private settings: RenderingContextSettings = new RenderingContextSettings(true)
  private context: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.settings)
  private img:ImageBitmap = new ImageBitmap("pages/example.jpg")
  build() {
    Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
      Canvas(this.context)
        .width('100%')
        .height('100%')
        .backgroundColor('#ffff00')
        .onReady(() =>{
          this.context.drawImage( this.img,0,0,500,500,0,0,400,200)
        })
    }
    .width('100%')
    .height('100%')
  }
}
