booleanWithin

描述

¥Description

如果第一个几何体完全位于第二个几何体之内，则 Boolean-within 返回 true。两个几何体的内部必须相交，并且主几何体（几何体 a）的内部和边界不得与次几何体（几何体 b）的外部相交。Boolean-within 返回的结果与 @turf/boolean-contains 完全相反。

¥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.
