pad_dict_by_visual_size#
- stimupy.utils.pad.pad_dict_by_visual_size(dct, padding, ppd, pad_value=0.0, keys=('img', '*mask'))#
Pad images in dictionary by specified degrees of visual angle
Can specify different amount (before, after) each axis.
- Parameters:
dct (dict) – dict containing image-arrays to be padded
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
keys (Sequence[String, String] or String) – keys in dict for images to be padded
- Returns:
same as input dict but with larger key-arrays and updated keys for “visual_size” and “shape”
- Return type:
