Instance Property

minimumSize

A float specifying the minimum size of the rectangle to be detected, as a proportion of the smallest dimension.

Declaration

var minimumSize: Float { get set }

Discussion

The value should range from 0.0 to 1.0 inclusive. The default minimum size is 0.2.

Any smaller rectangles that Vision may have detected aren't returned.
