decompose_glyph() [2/2]

MAYAFLUX_API GlyphOutline MayaFlux::Portal::Text::decompose_glyph	(	uint32_t	codepoint,
		float	tolerance = 0.5F
	)

Decompose a Unicode codepoint using the default atlas pixel size.

Convenience overload that reads pixel_size from TypeFaceFoundry's default atlas. Requires set_default_font() to have been called.

Parameters

codepoint	Unicode codepoint.
tolerance	Flatness tolerance in pixels.

Returns

GlyphOutline, or empty outline on failure.
