RendererRef

public struct RendererRef : RendererProtocol, GWeakCapturing

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 RendererRef type acts as a lightweight Swift reference to an underlying PangoRenderer instance. It exposes methods that can operate on this data type through RendererProtocol conformance. Use RendererRef only as an unowned reference to an existing PangoRenderer instance.

  • ptr 
    Untyped pointer to the underlying `PangoRenderer` instance.

    For type-safe access, use the generated, typed pointer renderer_ptr property instead.
