Geometry.normalize介绍

[英]Converts this Geometry to normal form (or canonical form ). Normal form is a unique representation for Geometry s. It can be used to test whether two Geometrys are equal in a way that is independent of the ordering of the coordinates within them. Normal form equality is a stronger condition than topological equality, but weaker than pointwise equality. The definitions for normal form use the standard lexicographical ordering for coordinates. "Sorted in order of coordinates" means the obvious extension of this ordering to sequences of coordinates.

NOTE that this method mutates the value of this geometry in-place. If this is not safe and/or wanted, the geometry should be cloned prior to normalization.
[中]将此Geometry转换为正常形式（或规范形式）。范式是Geometrys的唯一表示形式。它可用于测试两个Geometrys是否相等，其方式与它们内部坐标的顺序无关。正规形式等式是比拓扑等式更强的条件，但比逐点等式弱。标准形式的定义使用坐标的标准词典顺序。“按坐标顺序排序”是指这种排序对坐标顺序的明显扩展。
请注意，此方法会原地更改此几何图形的值。如果这不安全和/或不需要，则应在标准化之前克隆几何体。
