func rotate(byDegrees angle: CGFloat)
angleThe rotation angle, measured in degrees.
After invoking this method, applying the receiver’s matrix turns the axes counterclockwise about the current origin by angle degrees, in addition to performing all previous transformations.
func rotate(byApplies a rotation factor (measured in radians) to the receiver’s transformation matrix.
func scale(by: CGFloat)Applies the specified scaling factor along both x and y axes to the receiver’s transformation matrix.
func scaleApplies scaling factors to each axis of the receiver’s transformation matrix.
func translateApplies the specified translation factors to the receiver’s transformation matrix.
func append(AffineAppends the specified matrix to the receiver’s matrix.
func prepend(AffinePrepends the specified matrix to the receiver’s matrix.
func invert()Replaces the receiver’s matrix with its inverse matrix.
