booleanContains

描述

¥Description

如果第二个几何体完全包含在第一个几何体中，则 Boolean-contains 返回 True。两个几何体的内部必须相交，并且次级几何体（几何体 b）的内部和边界不得与主几何体（几何体 a）的外部相交。Boolean-contains 返回的结果与 @turf/boolean-within。

¥Boolean-contains returns True if the second geometry is completely contained by the first geometry. The interiors of both geometries must intersect and, the interior and boundary of the secondary (geometry b) must not intersect the exterior of the primary (geometry a). Boolean-contains returns the exact opposite result of the @turf/boolean-within.
