WEB GIS 开发框架 mapbox-gl-js v0.49 已发布,Mapbox GL JS 是一个 JavaScript 库,使用 WebGL 渲染交互式矢量瓦片地图和栅格瓦片地图。WebGL 渲染意味着高性能,MapboxGL 能够渲染大量的地图要素,拥有流畅的交互以及动画效果、可以显示立体地图并且支持移动端,是一款十分优秀的 WEB GIS(地理信息系统) 开发框架。
Breaking changes
Use
client{Height/Width}
instead ofoffset{Height/Width}
for map canvas sizing (#6848, fixed by #7128)
Bug 修复
Fix Top Issues list for mapbox-gl-js (#7108, fixed by #7112)
Fix bug in which symbols with
icon-allow-overlap: true, text-allow-overlap: true, text-optional: false
would show icons when they shouldn't (#7041)Fix bug where the map would not stop at the exact zoom level requested by Map#FlyTo (#7222) (#7223) (h/t benoitbzl)
Keep map centered on the center point of a multi-touch gesture when zooming (#6722) (#7191) (h/t pakastin)
Update the style-spec's old
gl-style-migrate
script to include conversion of legacy functions and filters to their expression equivalents (#6927, fixed by #7095)Fix
icon-size
for small data-driven values (#7125)Fix bug in the way AJAX requests load local files on iOS web view (#6610) (h/t oscarfonts)
Fix bug in which canvas sources would not render in world wrapped tiles at the edge of the viewport ([#7271]#7271), fixed by #7273)
功能改进

Add
symbol-z-order
symbol layout property to style spec (#7219)Implement data-driven styling support for
*-pattern properties
(#6289)Add
Map#fitScreenCoordinates
