ppd_from_shape_visual_size

stimupy.utils.resolution.ppd_from_shape_visual_size(shape, visual_size)

Calculate resolution (ppd) from given shape (pixels) and visual size (degrees)

Parameters:

• shape (Sequence[int, int]; or int, or None) – each element has to be of type that can be cast to int, or None. See validate_shape

• visual_size (Sequence[Number, Number]; or Number; or None) – each element has to be of type that can be cast to float, or None. See validate_visual_size

Returns:

.vertical: int, vertical pixels per degree (ppd) .horizontal: int, horizontal pixels per degree (ppd) see validate_ppd

Return type:

ppd NamedTuple, with two attributes
