Region

open class Region : RegionProtocol

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

  • ptr

    Untyped pointer to the underlying cairo_region_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 Region instance.

    Declaration

    Swift

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

    Declaration

    Swift

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

    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 RegionProtocol.

    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 RegionProtocol.

    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 RegionProtocol.

    Declaration

    Swift

    public convenience init(opaquePointer: OpaquePointer)
