描述

¥Description

Rotates any geojson Feature or Geometry of a specified angle, around its centroid or a given pivot point.

参数

名称	类型	描述
geojson	GeoJSON	要旋转的对象
angle	number	of rotation in decimal degrees, positive clockwise
options?	对象	可选参数（默认 ）
options.pivot?	坐标系	point around which the rotation will be performed (default 'centroid')
options.mutate?	boolean	allows GeoJSON input to be mutated (significant performance increase if true) (default false)

返回

¥Returns

GeoJSON the rotated GeoJSON feature

示例

¥Examples

  [
    [0, 29],
    [3.5, 29],
    [2.5, 32],
    [0, 29],
  ],
]);
const options = { pivot: [0, 25] };
const rotatedPoly = turf.transformRotate(poly, 10, options);
