lottie动画的json数据里不能有base64图片吗？

import lottie from ‘@ohos/lottie’ 
@Entry 
@Component 
struct LottiePage { 
  @State message: string = ‘Hello World’; 
  private mainRenderingSettings: RenderingContextSettings = new RenderingContextSettings(true) 
  private mainCanvasRenderingContext: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.mainRenderingSettings) 
  private path: string = “common/lottie/pulldown_loading.json” 
  build() { 
    Column() { 
      Canvas(this.mainCanvasRenderingContext) 
        .width(200) 
        .height(200) 
        .backgroundColor(Color.Gray) 
        .onReady(() => { 
          lottie.loadAnimation({ 
            container: this.mainCanvasRenderingContext, // 渲染上下文 
            renderer: ‘canvas’, // 渲染方式 
            loop: true, // 是否循环播放,默认true 
            autoplay: true, // 是否自动播放，默认true 
            name: ‘2016’, // 动画名称 
            path: this.path, // json路径 
            // initialSegment: [10, 50] // 播放的动画片段 
          }) 
        }) 
    } 
    .width(‘100%’) 
    .height(‘100%’) 
  } 
}
