IVideoWindow::put_BackgroundPalette

  • 项目

This method determines whether any palette required will be realized in the background.

HRESULT put_BackgroundPalette(
  long BackgroundPalette
);

Parameters

  • BackgroundPalette
    [in] OATRUE to realize the palette in the background; otherwise, OAFALSE.

Return Values

Returns an HRESULT value.

Remarks

If this is OATRUE (–1), any palette required by the video is realized by the renderer in the background. This means that any colors 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 when playing a video. It does, however, impose severe performance penalties on the video and should not be used unless absolutely necessary. The default value for this property is OAFALSE.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
