The GetColorKey method retrieves the current color key used for chroma keying.
Syntax
HRESULT GetColorKey(
COLORKEY *pColorKey
);
Parameters
pColorKey
[out] Pointer to a variable that receives the current color key for chroma keying.
Return Value
Returns S_OK if successful. If the method fails, it returns an HRESULT error code.
Remarks
If you change the color key by using the IOverlay::SetColorKey method, all the advise links receive an IOverlayNotify::OnColorKeyChange callback method with the new color.
If no color key is currently being used, this method returns VFW_E_NO_COLOR_KEY_SET.
