函数: transformTranslate()

transformTranslate<T>(geojson: T, distance: number, direction: number, options?: { units?: Units; zTranslation?: number; mutate?: boolean; }): T

Function

Moves any geojson Feature or Geometry of a specified distance along a Rhumb Line on the provided direction angle.

Note that this moves the points of your shape individually and can therefore change the overall shape. How noticable this is depends on the distance and the used projection.

类型参数

T

T extends GeometryCollection<Geometry> | GeoJSON

参数

geojson

T

object to be translated

distance

number

length of the motion; negative values determine motion in opposite direction

direction

number

of the motion; angle from North in decimal degrees, positive clockwise

options?

Optional parameters

units?

Units

in which distance will be expressed; Supports all valid Turf Units

zTranslation?

number

length of the vertical motion, same unit of distance

mutate?

boolean

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

返回

T

the translated GeoJSON object

示例

var poly = turf.polygon([[[0,29],[3.5,29],[2.5,32],[0,29]]]);
var translatedPoly = turf.transformTranslate(poly, 100, 35);

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