类名称：GeometryFactory
方法名：toGeometry

GeometryFactory.toGeometry介绍

[英]Creates a Geometry with the same extent as the given envelope. The Geometry returned is guaranteed to be valid. To provide this behaviour, the following cases occur:

If the Envelope is:

  • null : returns an empty Point
  • a point : returns a non-empty Point
  • a line : returns a two-point LineString
  • a rectangle : returns a Polygon> whose points are (minx, miny), (minx, maxy), (maxx, maxy), (maxx, miny), (minx, miny).
    [中]创建与给定封套具有相同范围的几何图形。返回的几何图形保证有效。为了提供这种行为，出现以下情况：
    如果Envelope为：
    *null：返回一个空点
    *点：返回一个非空点
    *线：返回两点线字符串
    *矩形：返回一个多边形>，其点为（minx，miny），（minx，maxy），（maxx，maxy），（maxx，miny），（minx，miny）。
