Shapely centroid of linestring
Webb23 apr. 2024 · 5. While working with shapely I faced a strange issue. There're 2 points p1 and p2, where the first one belongs to polygon and the second is not. When I tried to find intersection between the LineString containing these 2 points as endpoints with boundary lines of the Polygon, I received message that no intersection was found. Webb30 mars 2016 · Shapely allows you to calculate intersections between polygons, and so the solution gets quite simple: For both the horizontal and the vertical line running through the centroid of your contour, you just calculate the intersections with the contour and draw lines to those intersections.
