函数: transformRotate()

transformRotate<T>(geojson: T, angle: number, options?: { pivot?: Coord; mutate?: boolean; }): T

Function

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

类型参数

T

T extends GeometryCollection<Geometry> | GeoJSON

参数

geojson

T

object to be rotated

angle

number

of rotation in decimal degrees, positive clockwise

options?

Optional parameters

pivot?

Coord

point around which the rotation will be performed

mutate?

boolean

allows GeoJSON input to be mutated (significant performance increase if true)

返回

T

the rotated GeoJSON feature

示例

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

//addToMap
const addToMap = [poly, rotatedPoly];
rotatedPoly.properties = {stroke: '#F00', 'stroke-width': 4};
