示例

初始化一个二维场景草图编辑类

// [ES5引入方式]：
const { MapView } = zondy.video
const { SketchEditor } = zondy.video.tool.sketch
[ES6引入方式]：
import { MapView, SketchEditor } from "@mapgis/webclient-leaflet-plugin" <br/>
import { SketchStyle, SimpleMarkerSymbol, Color, SketchDataType} from "@mapgis/webclient-common" <br/>
var map = new Map()
var mapView = new MapView({
  viewId: "mapgis-2d-viewer",
  map: map,
})
var videoLayer = new VideoMapLayer({})
mapView.add(videoLayer)
var simpleMarkerSymbol = new SimpleMarkerSymbol({
  color: new Color(24, 144, 255, 1),
  size: 10,
});
var sketchStyle = new SketchStyle({
  vertexStyle: simpleMarkerSymbol,
    lineStyle: undefined,
    fillStyle: undefined
  })
var sketchEditor = new SketchEditor({
  view: mapView,
  layer: new GraphicsLayer(),
  vertexStyle: vertexStyle
})
sketchEditor.start(SketchDataType.POINT) // 绘制点
sketchEditor.start(SketchDataType.POLYLINE) // 绘制线
sketchEditor.start(SketchDataType.POLYGON) // 绘制区
