Hi,

How do convert correct RGB color to YUV for Video Overlay Color Key
for DirectX with 16 Bit color video display.

Is the below code correct? I found it only work for 24 or 32 Bit color

ddofx.dckDestColorkey.dwColorSpaceLowValue  =
     RGB( GetBValue(clOverYUV),GetGValue(clOverYUV),GetRValue(clOverYUV) );
ddofx.dckDestColorkey.dwColorSpaceHighValue =
    RGB( GetBValue(clOverYUV),GetGValue(clOverYUV),GetRValue(clOverYUV) );

Many thx in advanced.

Regards
KL Chin
