Converts YUV color values to RGB color values.

Syntax

XMVECTOR XM_CALLCONV XMColorYUVToRGB(
  [in] FXMVECTOR yuv
) noexcept;

Parameters

[in] yuv

Color value to convert in Luma-Chrominance (YUV) aka YCbCr. The X element contains Luma (Y, 0.0 to 1.0), the Y element contains Blue-difference chroma (U, -0.5 to 0.5), the Z element contains the Red-difference chroma (V, -0.5 to 0.5), and the W element contains the Alpha (0.0 to 1.0).

Return value

The converted color value. X element is Red, Y element is Green, Z element is Blue, and W element is Alpha (a copy of yuv.w). Each has a range of 0.0 to 1.0.

Remarks

Converts using ITU-R BT.601/CCIR 601 W(r) = 0.299 W(b) = 0.114 U(max) = 0.436 V(max) = 0.615.
