Bounds

Extends:

leaflet~L.Bounds → Bounds

以像素为单位表示一个矩形区域

Constructor Summary

Public Constructor
public	constructor(topLeft: Point, bottomRight: Point) 构造函数

Method Summary

Public Methods
public	contains(point: Point \| Bounds): Boolean 如果矩形区域包含给定对象则返回true
public	extend(point: Point): Bounds 扩展矩形区域，使之能容纳点
public	getBottomLeft(): Point 返回矩形区域的左下角点
public	getCenter(isRound: Boolean): Point 返回矩形区域的中心点
public	getSize(): Point 返回矩形区域的大小
public	getTopRight(): Point 返回矩形区域的右上角点
public	intersects(otherBounds: Bounds): Boolean 如果矩形区域与给定的矩形区域相交则返回true。如果它们有一个点相交就会被判定为相交。
public	overlaps(otherBounds: Bounds): Boolean 如果矩形区域与给定的矩形区域重叠则返回true。两块区域如果相交的是一块区域则被判定为重叠。
