white(visual_size=None, ppd=None, shape=None, intensity_range=(0, 1), pseudo_noise=False)[source]#

Draw white noise texture

Parameters:

  • visual_size (Sequence[Number, Number], Number, or None (default)) – visual size [height, width] of grating, in degrees

  • ppd (Sequence[Number, Number], Number, or None (default)) – pixels per degree [vertical, horizontal]

  • shape (Sequence[Number, Number], Number, or None (default)) – shape [height, width] of grating, in pixels

  • intensity_range (Sequence[Number, Number]) – minimum and maximum intensity value; default: (0, 1)

  • pseudo_noise (bool) – if True, generate pseudo-random noise with ideal power spectrum

Return type:

A stimulus dictionary with the noise array [‘img’]
