Aperture
¶psychopy.visual.
Aperture
(win, size=1, pos=(0, 0), ori=0, nVert=120, shape='circle', inverted=False, units=None, name=None, autoLog=None)¶Restrict a stimulus visibility area to a basic shape or list of vertices.
When enabled, any drawing commands will only operate on pixels within the Aperture. Once disabled, subsequent draw operations affect the whole screen as usual.
If shape is ‘square’ or ‘triangle’ then that is what will be used If shape is ‘circle’ or None then a polygon with nVerts will be used
(120 for a rough circle)

in the image (e.g. in a PNG file) will not be included in the mask
