visual_size (Sequence[Number, Number], Number, or None (default)) – visual size [height, width] of image, 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 image, in pixels
target_size (float or (float, float)) – size [height, width] of the target, in degrees visual angle
intensity_background (float, optional) – intensity value for background, by default 0.0
intensity_target (float, optional) – intensity value for target, by default 0.5
- Returns:
