get_rectangle_centroid

pyhelpers.geom.get_rectangle_centroid(rectangle, as_geom=False)

Get coordinates of the centroid of a rectangle

Parameters

• rectangle (list or tuple or numpy.ndarray or shapely.geometry.Polygon or shapely.geometry.MultiPolygon) – polygon or multipolygon geometry object

• as_geom (bool) – whether to return a shapely.geometry object

Returns

coordinate of the rectangle

Return type

numpy.ndarray or shapely.geometry.Point

Examples:

>>> from pyhelpers.geom import get_rectangle_centroid
>>> from shapely.geometry import Polygon
>>> import numpy

>>> vtx_coords = [[0, 0], [0, 1], [1, 1], [1, 0]]

>>> rect_obj = Polygon(vtx_coords)
>>> rect_cen = get_rectangle_centroid(rectangle=rect_obj)
>>> rect_cen
array([0.5, 0.5])

>>> rect_obj = numpy.array(vtx_coords)
>>> rect_cen = get_rectangle_centroid(rectangle=rect_obj)
>>> rect_cen
array([0.5, 0.5])

>>> rect_cen = get_rectangle_centroid(rectangle=rect_obj, as_geom=True)
>>> type(rect_cen)
shapely.geometry.point.Point
>>> rect_cen.wkt
'POINT (0.5 0.5)'

>>> vtx_coords_ = [[(0, 0), (0, 1), (1, 1), (1, 0)], [(1, 1), (1, 2), (2, 2), (2, 1)]]
