GlyphGeometry

open class GlyphGeometry : GlyphGeometryProtocol

The PangoGlyphGeometry structure contains width and positioning information for a single glyph.

Note that width is not guaranteed to be the same as the glyph extents. Kerning and other positioning applied during shaping will affect both the width and the x_offset for the glyphs in the glyph string that results from shaping.

The information in this struct is intended for rendering the glyphs, as follows:

  1. Assume the current point is (x, y)
  2. Render the current glyph at (x + x_offset, y + y_offset),
  3. Advance the current point to (x + width, y)
  4. Render the next glyph

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

  • ptr
    Untyped pointer to the underlying `PangoGlyphGeometry` 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. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GlyphGeometry instance.

    Declaration

    Swift

    @inlinable
    public init(_ op: UnsafeMutablePointer<PangoGlyphGeometry>)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GlyphGeometry instance.

    Declaration

    Swift

    @inlinable
    public init(_ op: UnsafePointer<PangoGlyphGeometry>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GlyphGeometry instance.

    Declaration

    Swift

    @inlinable
    public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GlyphGeometry instance.

    Declaration

    Swift

    @inlinable
    public init!(gconstpointer op: gconstpointer?)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GlyphGeometry instance.

    Declaration

    Swift

    @inlinable
    public init!(_ op: UnsafePointer<PangoGlyphGeometry>?)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GlyphGeometry instance.

    Declaration

    Swift

    @inlinable
    public init!(_ op: UnsafeMutablePointer<PangoGlyphGeometry>?)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from the underlying C data type. PangoGlyphGeometry does not allow reference counting, so despite the name no actual retaining will occur. i.e., ownership is transferred to the GlyphGeometry instance.

    Declaration

    Swift

    @inlinable
    public init(retaining op: UnsafeMutablePointer<PangoGlyphGeometry>)

    Parameters

    op

    pointer to the underlying object

  • Reference intialiser for a related type that implements GlyphGeometryProtocol PangoGlyphGeometry does not allow reference counting.

    Declaration

    Swift

    @inlinable
    public init<T>(_ other: T) where T : GlyphGeometryProtocol

    Parameters

    other

    an instance of a related type that implements GlyphGeometryProtocol

  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to GlyphGeometryProtocol.

    @inlinable
    public init<T>(cPointer p: UnsafeMutablePointer<T>)

    Parameters

    cPointer
