Class VNPoint

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    Direct Known Subclasses:
    VNDetectedPoint
    public class VNPoint
extends NSObject
implements NSCopying, NSSecureCoding
    VNPoint VNPoint represents a single, immutable, two-dimensional point in an image. It should be noted that VNPoint is not intended as an overall replacement of CGPoint, NSPoint or vec2, but is used by observations that need to present points which may contain additional metadata.
