10.1.4.13.1. ArrowHead¶

Module to implement arrow head.

class Patro.GeometryEngine.Shape.ArrowHead.ArrowHead(point, direction)[source]¶

Bases: object

Base class to implement arrow head.

An arrow head (tip) is placed at an anchor point along a direction (support line). It can be placed at a segment extremities or shifted from an extremity, for example for multiple tips.

__init__(point, direction)[source]¶

Initialize self. See help(type(self)) for accurate signature.
