const color_t *	video::color_vectors_from_colorspace (const sunshine_colorspace_t &colorspace, bool unorm_output)
	Get static RGB->YUV color conversion matrix. This matrix expects RGB input in UNORM (0.0 to 1.0) range and doesn't perform any gamut mapping or gamma correction.

Function Documentation

color_vectors_from_colorspace()

const color_t * video::color_vectors_from_colorspace	(	const sunshine_colorspace_t &	colorspace,
		bool	unorm_output )

Get static RGB->YUV color conversion matrix. This matrix expects RGB input in UNORM (0.0 to 1.0) range and doesn't perform any gamut mapping or gamma correction.

Parameters

colorspace	Targeted YUV colorspace.
unorm_output	Whether the matrix should produce output in UNORM or UINT range.

Returns

const color_t* that contains RGB->YUV transformation vectors. Components range_y and range_uv are there for backwards compatibility and can be ignored in the computation.
