tracingStreamLinesAsync

tracingStreamLinesAsync(options: ITracingStreamlineOptions, completeOne?: ((data: { allFC: FeatureCollection<LineString, {}>; fc: FeatureCollection<LineString, {}>; streamlines: number[][][] }) => void)): Promise<{ provider: GeoJSONFeatureProvider; streamlines: number[][][] }>

- Defined in src/services/tracing.service.ts:1090
对格点数据进行风流场追踪，分析的结果是矢量provider 对于显示静态风流场，可以添加一个箭头来表示风的方向，矢量样式需要一个箭头方向朝右的图片来作为贴图参考配置如下（贴图为32x32，显示为16x16，以便在Retina屏下获得较好的效果）： { polyline: { color: "black", label: [ { image: { data: "arrow#res", //arrow为贴图的资源id，关于资源的使用请参考文档 size: [16, 16], offset: [-8, -8] } } ], labelAutoFlip: false //务必设置为false，避免系统自动翻转箭头的方向 } }

Parameters
- options: ITracingStreamlineOptions
  
  追踪选项
- Optional completeOne: ((data: { allFC: FeatureCollection<LineString, {}>; fc: FeatureCollection<LineString, {}>; streamlines: number[][][] }) => void)
  
  当一个批次追踪结束时的回调，一般用于大量数据时分批渐进显示，可以提供较好的用户体验。也可以直接等最终全部分析完成再显示
  - - (data: { allFC: FeatureCollection<LineString, {}>; fc: FeatureCollection<LineString, {}>; streamlines: number[][][] }): void
    - Parameters
      - data: { allFC: FeatureCollection<LineString, {}>; fc: FeatureCollection<LineString, {}>; streamlines: number[][][] }
        allFC: FeatureCollection<LineString, {}>
