Constructor & Destructor Documentation

AiksContext()

impeller::AiksContext::AiksContext	(	std::shared_ptr< Context >	context,
		std::shared_ptr< TypographerContext >	typographer_context
	)

Construct a new AiksContext.

Parameters

context	The Impeller context that Aiks should use for allocating resources and executing device commands. Required.
typographer_context	The text backend to use for rendering text. If nullptr is supplied, then attempting to draw text with Aiks will result in validation errors.
