Matrix

open class Matrix : MatrixProtocol

The Matrix type acts as an owner of an underlying cairo_matrix_t instance. It provides the methods that can operate on this data type through MatrixProtocol conformance. Use Matrix as a strong reference or owner of a cairo_matrix_t instance.

  • ptr

    Untyped pointer to the underlying cairo_matrix_t instance. For type-safe access, use the generated, typed pointer _ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer
  • Designated initialiser from the underlying C data type. Ownership is transferred to the Matrix instance.

    Declaration

    Swift

    public init(_ op: UnsafeMutablePointer<cairo_matrix_t>)
  • Reference convenience intialiser for a related type that implements MatrixProtocol cairo_matrix_t does not allow reference counting.

    Declaration

    Swift

    public convenience init<T>(_ other: T) where T : MatrixProtocol
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to MatrixProtocol.

    Declaration

    Swift

    public convenience init<T>(cPointer: UnsafeMutablePointer<T>)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to MatrixProtocol.

    Declaration

    Swift

    public convenience init(raw: UnsafeRawPointer)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to MatrixProtocol.

    Declaration

    Swift

    public convenience init(raw: UnsafeMutableRawPointer)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to MatrixProtocol.

    Declaration

    Swift

    public convenience init(opaquePointer: OpaquePointer)
