基于 WebGL 的矢量地图，Mapbox GL 0.9.0 发布

jopen 9年前

Mapbox GL 是基于 WebGL 的客户端矢量地图，也是个 JavaScript 库。

Mapbox GL 0.9.0 发布，更新内容如下：

  • glyphs URL now normalizes without the /v4/ prefix for mapbox:// urls. Legacy behavior for mapbox://fontstacks is still maintained (#1385)

  • Expose geojson-vt options for GeoJSON sources (#1271)

  • bearing snaps to "North" within a tolerance of 7 degrees (#1059)

  • Now you can directly mutate the minzoom and maxzoom layer properties with map.setLayerZoomRange(layerId, minzoom, maxzoom)

  • Exposed mapboxgl.Control, a base class used by all UI controls

  • Refactored handlers to be individually included in Map options, or enable/disable them individually at runtime, e.g. map.scrollZoom.disable().

  • New feature: Batch operations can now be done at once, improving performance for calling multiple style functions: (#1352)

        s.addLayer({ id: 'second', type: 'symbol', source: 'streets' });
        s.addLayer({ id: 'third', type: 'symbol', source: 'terrain' });
        s.setPaintProperty('first', 'text-color', 'black');
        s.setPaintProperty('first', 'text-halo-color', 'white');
