有没有办法在地图上拉伸mapbox Point的高度? 有以下例子:
map.addSource("markers", {
"type": "geojson",
"data": {
"type": "FeatureCollection",
"features": [{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [14.422063225409431,50.08273361716846]
},
"properties": {
"height": 12,
"base_height": 10,
"title": "Mapbox DC",
"marker-symbol": "spaceti-maintenance"
}
}, {
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [14.421896271941648,50.08259946060207]
},
"properties": {
"height": 12,
"base_height": 10,
"title": "Mapbox SF",
"marker-symbol": "spaceti-maintenance"
}
}]
}
});
map.addLayer({
"id": "markers",
"source": "markers",
//"type": "symbol",
"type":"fill-extrusion",
// "layout": {
// "icon-image": "{marker-symbol}",
// "text-field": "{title}",
// "text-font": ["Open Sans Semibold", "Arial Unicode MS Bold"],
// "text-offset": [0, 0.6],
// "text-anchor": "top"
// },
"paint": {
// See the Mapbox Style Spec for details on property functions
// https://www.mapbox.com/mapbox-gl-style-spec/#types-function
"fill-extrusion-color": "#424242",
"fill-extrusion-height": {
// Get fill-extrusion-height from the source "height" property.
"property": "height",
"type": "identity"
},
"fill-extrusion-base": {
// Get fill-extrusion-base from the source "base_height" property.
"property": "base_height",
"type": "identity"
},
// Make extrusions slightly opaque for see through indoor walls.
"fill-extrusion-opacity": 0.90
}
});
我是否能够使用图层的布局和绘制属性,假设我想要自定义图标+拉伸高度的标记?我正在建造多层室内导航,这就是原因。
