padding (float, or Sequence[float, float], or Sequence[Sequence[float, float], ...]) – amount of padding, in degrees visual angle, in each direction: ((before_1, after_1), … (before_N, after_N)) unique pad widths for each axis (float,) or float is a shortcut for before = after = pad width for all axes.
ppd (Sequence[Number] or Sequence[Number, Number]) – pixels per degree
pad_value (Numeric, optional) – value to pad with, by default 0.0
