The clip_by_rect() function in shapely.ops returns the portion of a geometry within a rectangle.
shapely.ops中的clip_by_rect()函数返回一个几何对象在矩形内的部分。
- shapely.ops.clip_by_rect(geom, xmin, ymin, xmax, ymax)
The geometry is clipped in a fast but possibly dirty way. The output is not guaranteed to be valid. No exceptions will be raised for topological errors.
几何对象以一种快速但可能是粗糙的方式被剪掉。输出不保证是有效的。对于拓扑结构的错误，将不会产生异常。
