press() [1/2]

MAYAFLUX_API std::shared_ptr< Buffers::TextBuffer > MayaFlux::Portal::Text::press	(	std::string_view	text,
		const PressParams &	params = {}
	)

Composite a UTF-8 string into a new TextBuffer.

The returned TextBuffer has width == params.render_bounds.x and height equal to either the explicit params.budget_h or the heuristic initial allocation, whichever is larger than the content height.

Parameters

text	UTF-8 string to composite.
params	Construction parameters. Default produces a growing buffer at 1280x720 render bounds using the default atlas.

Returns

Initialized TextBuffer, or nullptr on failure.
