D3D11_VIDEO_COLOR_YCbCrA structure (d3d11.h)
Specifies a YCbCr color value.
Syntax
typedef struct D3D11_VIDEO_COLOR_YCbCrA {
float Y;
float Cb;
float Cr;
float A;
} D3D11_VIDEO_COLOR_YCbCrA;
Members
Y
The Y luma value.
Cb
The Cb chroma value.
Cr
The Cr chroma value.
A
The alpha value. Values range from 0 (transparent) to 1 (opaque).
Remarks
Values have a nominal range of [0...1]. Given a format with n bits per channel, the value of each color component is calculated as follows:
val = f * ((1 << n)-1)
For example, for 8-bit YUV formats, val = BYTE(f * 255.0). Reference black is (0.0625, 0.5, 0.5), which corresponds to (16, 128, 128) in an 8-bit representation.
