	New version of color_vectors_from_colorspace() function that better adheres to the standards. Returned vectors are used to perform RGB->YUV conversion. Unlike its predecessor, color vectors will produce output in UINT range, not UNORM range. Input is still in UNORM range. Returned vectors won't modify color primaries and color transfer function.

Function Documentation

new_color_vectors_from_colorspace()

const color_t * video::new_color_vectors_from_colorspace

(

const sunshine_colorspace_t &

colorspace

)

New version of color_vectors_from_colorspace() function that better adheres to the standards. Returned vectors are used to perform RGB->YUV conversion. Unlike its predecessor, color vectors will produce output in UINT range, not UNORM range. Input is still in UNORM range. Returned vectors won't modify color primaries and color transfer function.

Parameters

colorspace

Targeted YUV colorspace.

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.
