Renderer

The renderer translates model nodes into backend draw calls. A concrete renderer (e.g. PDF) dispatches each node type to the appropriate painter.

DocraftAbstractRenderer

Abstract base with a virtual method per node type.

class DocraftAbstractRenderer

Abstract renderer that converts model nodes into backend draw calls.

Concrete renderers (e.g., PDF) implement each node type using painters and the document context’s rendering backend.

Subclassed by docraft::renderer::DocraftPDFRenderer
