The put_BackgroundPalette method specifies whether the video window realizes its palette in the background.
Syntax
HRESULT put_BackgroundPalette(
long BackgroundPalette
);
Parameters
BackgroundPalette
[in] Value that specifies whether the video renderer realizes it palette in the background. Must be one of the following values:
| Value | Description |
| OATRUE | The video renderer realizes the palette in the background. |
| OAFALSE | The video renderer does not realize the palette in the background. (Default.) |
Return Values
Possible return values include the following:
| Value | Description |
| E_INVALIDARG | Invalid argument. |
| S_OK | Success. |
| VFW_E_NOT_CONNECTED | The pins are not connected. |
Remarks
If BackgroundPalette is OATRUE and the video image requires a pallette, the video renderer will realize that palette in the background. Any colors that the palette uses will change to their closest match in the display palette prior to drawing. This ensures that an application will not have its palette disturbed. However, it imposes severe performance penalties on the video.
