wedge

Draw a wedge, i.e., segment of a disc

segments

Generate mask with integer indices for sequential angular segments
wedge(visual_size=None, ppd=None, shape=None, angle=None, radius=None, rotation=0.0, inner_radius=0.0, intensity_wedge=1.0, intensity_background=0.0, origin='mean')[source]#

Draw a wedge, i.e., segment of a disc

Parameters:

  • 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

  • angle (float) – angular-width (in degrees) of segment

  • radius (float) – radius of disc, in degrees visual angle

  • rotation (float, optional) – rotation (in degrees) from 3 o’clock, counterclockwise, by default 0.0

  • inner_radius (float, optional) – inner radius (in degrees visual angle), to turn disc into a ring, by default 0

  • intensity_wedge (float, optional) – intensity value of wedge, by default 1.0

  • intensity_background (float, optional) – intensity value of background, by default 0.0

  • origin ("corner", "mean" or "center") – if “corner”: set origin to upper left corner if “mean”: set origin to hypothetical image center (default) if “center”: set origin to real center (closest existing value to mean)

Returns:

dict with the stimulus (key: “img”), mask with integer index for each segment (key: “wedge_mask”), and additional keys containing stimulus parameters

Return type:

dict[str, Any]

segments(visual_size=None, ppd=None, shape=None, angles=None, rotation=0.0, intensity_background=0.5, intensity_segments=(0.0, 1.0), origin='mean')[source]#

Generate mask with integer indices for sequential angular segments

Parameters:

  • 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

  • angles (Sequence[Number] or None (default)) – upper-limit of each segment, in angular degrees 0-360

  • rotation (float, optional) – rotation (in degrees) from 3 o’clock, counterclockwise, by default 0.0

  • intensity_background (Number) – intensity value for background; default is 0.5.

  • intensity_segments (Sequence[Number, ...]) – intensity value for each segment, from inside to out. If fewer intensities are passed than number of radii, cycles through intensity_segments

  • origin ("corner", "mean" or "center") – if “corner”: set origin to upper left corner if “mean”: set origin to hypothetical image center (default)angles if “center”: set origin to real center (closest existing value to mean)

Returns:

dict with the stimulus (key: “img”), mask with integer index for each segment (key: “segment_mask”), and additional keys containing stimulus parameters

Return type:

dict[str, Any]
