# booleanWithin

Boolean-within returns true if the first geometry is completely within the second geometry. The interiors of both geometries must intersect and, the interior and boundary of the primary (geometry a) must not intersect the exterior of the secondary (geometry b). Boolean-within returns the exact opposite result of the @turf/boolean-contains.
如果第一个几何图形完全位于第二个几何图形中,则返回true。两个几何图形的内部必须相交,并且主图形的内部和边界(几何图形a)不能与次要图形的外部(几何图形b)相交。Boolean-within@turf/boolean-contains完全相反的结果。

参数

参数 类型 描述
feature1 (Geometry|Feature) GeoJSON Feature or Geometry
feature2 (Geometry|Feature) GeoJSON Feature or Geometry

返回

boolean - true/false

示例

var line = turf.lineString([[1, 1], [1, 2], [1, 3], [1, 4]]);
var point = turf.point([1, 2]);

turf.booleanWithin(point, line);
//=true
