This method returns the current color control settings associated with the specified overlay or primary surface. The dwFlags member of the DDCOLORCONTROL structure indicates which of the color control options are supported.
Syntax
HRESULT GetColorControls(
LPDDCOLORCONTROL lpColorControl
);
Parameters
- lpColorControl
Address of the DDCOLORCONTROL structure that will receive the current control settings of the specified surface.
Return Value
If the method succeeds, the return value is DD_OK.
If the method fails, the return value may be one of the following error values:
DDERR_INVALIDOBJECT |
DDERR_INVALIDPARAMS |
DDERR_UNSUPPORTED |
For more information on these error codes see DirectDraw Return Values.
Remarks
The first structure member, dwSize, should be set to the size of the structure, in bytes, before you use it.
When retrieving color controls, you do not need to set the dwFlags before using it — it will contain flags telling you which members are valid after the IDirectDrawColorControl::GetColorControls method returns.
The remaining DDCOLORCONTROL structure members will contain values that describe the brightness, contrast, hue, saturation, sharpness, gamma, and whether color is used.
