CGPoint

public extension CGPoint

  • Rotate this point around a given point, by an angle given in degrees.

    Declaration

    Swift

    func rotated(around inCenter: CGPoint, byDegrees inDegrees: CGFloat, precisionInDecimalPlaces inPrecision: UInt8? = nil) -> CGPoint

    Parameters

    around

    Another point, that is the “fulcrum” of the rotation.
    byDegrees

    The rotation angle, in degrees. 0 is no change. - is counter-clockwise, + is clockwise.
    precisionInDecimalPlaces

    The precision, in decimal places to the right of the decimal. This is optional, and, if omitted, uses full precision.

    Return Value

    The transformed point.

  • This was inspired by this SO answer. Rotate this point around a given point, by an angle given in radians.

    Declaration

    Swift

    func rotated(around inCenter: CGPoint, byRadians inRadians: CGFloat, precisionInDecimalPlaces inPrecision: UInt8? = nil) -> CGPoint

    Parameters

    around

    Another point, that is the “fulcrum” of the rotation.
    byRadians

    The rotation angle, in radians. 0 is no change. - is counter-clockwise, + is clockwise.
    precisionInDecimalPlaces

    The precision, in decimal places to the right of the decimal. This is optional, and, if omitted, uses full precision. The range is 0…14.

    Return Value

    The transformed point.
