geopandas.GeoSeries.skew

GeoSeries.skew(xs=0.0, ys=0.0, origin='center', use_radians=False)

Returns a GeoSeries with skewed geometries.

The geometries are sheared by angles along the x and y dimensions.

See http://shapely.readthedocs.io/en/latest/manual.html#shapely.affinity.skew for details.

Parameters
xs, ysfloat, float

The shear angle(s) for the x and y axes respectively. These can be specified in either degrees (default) or radians by setting use_radians=True.

originstring, Point, or tuple (x, y)

The point of origin can be a keyword ‘center’ for the bounding box center (default), ‘centroid’ for the geometry’s centroid, a Point object or a coordinate tuple (x, y).

use_radiansboolean

Whether to interpret the shear angle(s) as degrees or radians
