过滤注记要素

使用示例

<script>
    var map = L.map('map', {
        crs: L.CRS.CustomEPSG4326,
        center: {lon: 120.11215287988154, lat: 30.177052933991797},
        zoom: 12,
        inertiaDeceleration: 15000,
        maxZoom: 20
    })
    //添加注记
    var labelLayer = new L.GWVTAnno({tileSize: 512})
    var dataSource = new Custom.URLDataSource()
    dataSource.url = window.leaflet.labelUrl + '&x={x}&y={y}&l={z}'

    //过滤，只显示设置的要素
    var filter = new Custom.Filter()
    filter.otherDisplay = false

    var filterLayer = new Custom.FilterLayer()
    filterLayer.id = '交通_交通注记_公路'
    filter.addFilterLayer(filterLayer)

    dataSource.setFilter(filter)
    labelLayer.addDataSource(dataSource)
    map.addLayer(labelLayer)
</script>
