【iClient】iClient for MapboxGL,如何改线设置箭头符号，且箭头方向和线方向保证一致？

Answer 1

【解决办法】示例代码如下 map.addLayer({ id: "line", source: "line", type: "symbol", layout: { "text-field": "▶", "text-transform": "uppercase", "text-keep-upright": false, "text-rotation-alignment": "map", "symbol-placement": "line-center", "text-size": 12, } }) 主要注意text-keep-upright默认为true，需设置为false，箭头即可沿着线的方向渲染
