Renderer

open class Renderer : GLibObject.Object, RendererProtocol

PangoRenderer is a base class for objects that can render text provided as PangoGlyphString or PangoLayout.

By subclassing PangoRenderer and overriding operations such as draw_glyphs and draw_rectangle, renderers for particular font backends and destinations can be created.

The Renderer type acts as a reference-counted owner of an underlying PangoRenderer instance. It provides the methods that can operate on this data type through RendererProtocol conformance. Use Renderer as a strong reference or owner of a PangoRenderer instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Renderer instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • 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 Renderer instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • 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 Renderer instance.

    Declaration

    Swift

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

    Parameters

    op

    gpointer to the underlying object
    Show on GitHub

  • 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 Renderer instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
