## 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`.
|
|
|
|
**Parameters**
|
|
|
|
- `feature1` **([Geometry][1] \| [Feature][2]<any>)** GeoJSON Feature or Geometry
|
|
- `feature2` **([Geometry][1] \| [Feature][2]<any>)** GeoJSON Feature or Geometry
|
|
|
|
**Examples**
|
|
|
|
```javascript
|
|
var line = turf.lineString([[1, 1], [1, 2], [1, 3], [1, 4]]);
|
|
var point = turf.point([1, 2]);
|
|
|
|
turf.booleanWithin(point, line);
|
|
//=true
|
|
```
|
|
|
|
Returns **[boolean][3]** true/false
