  • width (float) – Width of rectangle in pixels

  • height (float) – Height of rectangle in pixels

  • shift (tuple of floats, optional) – How far to shift center in (rows, cols). Default is (0, 0).

  • angle (float, optional) – Rotation of rectangle in degrees counterclockwise from horizontal. Default is 0.

  • antialias (bool, optional) – If True (default), the shape edges are antialiased.

  • indexing ({'ij', 'xy'}, optional) – Matrix (‘ij’, default) or cartesian (‘xy’) indexing of output.
