NSAffineTransform

class NSAffineTransform

Superclasses

protocol CustomDebugStringConvertible
A type with a customized textual representation suitable for debugging purposes.
protocol CustomStringConvertible
A type with a customized textual representation.
protocol Equatable
A type that can be compared for value equality.
protocol Hashable
A type that can be hashed into a Hasher to produce an integer hash value.
protocol NSCoding
The NSCoding protocol declares the two methods that a class must implement so that instances of that class can be encoded and decoded. This capability provides the basis for archiving (where objects and other structures are stored on disk) and distribution (where objects are copied to different address spaces).
protocol NSCopying
The NSCopying protocol declares a method for providing functional copies of an object. The exact meaning of “copy” can vary from class to class, but a copy must be a functionally independent object with values identical to the original at the time the copy was made.
protocol NSObjectProtocol
The NSObjectProtocol groups methods that are fundamental to all Foundation objects.
protocol NSSecureCoding
Conforming to the NSSecureCoding protocol indicates that an object handles encoding and decoding instances of itself in a manner that is robust against object substitution attacks.

init()
Initializes an affine transform matrix to the identity matrix.
init?(coder: NSCoder)
convenience init(transform: AffineTransform)
Initializes an affine transform matrix using another transform object.
static let supportsSecureCoding: Bool
var hash: Int
var transformStruct: NSAffineTransformStruct
The matrix coefficients stored as the transformation matrix.
func append(AffineTransform)
Appends the specified matrix.
func copy() -> Any
func copy(with: NSZone?) -> Any
func encode(with: NSCoder)
func invert()
Replaces the matrix with its inverse matrix.
func isEqual(Any?) -> Bool
func prepend(AffineTransform)
Prepends the specified matrix.
func rotate(byDegrees: CGFloat)
Applies a rotation factor (measured in degrees) to the transformation matrix.
func rotate(byRadians: CGFloat)
Applies a rotation factor (measured in radians) to the transformation matrix.
func scale(by: CGFloat)
Applies the specified scaling factor along both x and y axes to the transformation matrix.
func scaleX(by: CGFloat, yBy: CGFloat)
Applies scaling factors to each axis of the transformation matrix.
func transform(CGSize) -> CGSize
Applies the transform to the specified size and returns the result.
func transform(CGPoint) -> CGPoint
Applies the transform to the specified point and returns the result.
func translateX(by: CGFloat, yBy: CGFloat)
Applies the specified translation factors to the transformation matrix.
