IOverlay::SetPalette

  • Article

This method sets the palette.

HRESULT SetPalette(
  DWORD dwColors,
  PALETTEENTRY* pPalette
);

Parameters

  • dwColors
    [in] Number of colors present.
  • pPalette
    [in] Colors to use for the palette.

Return Values

Returns an HRESULT value that depends on the implementation. HRESULT can be one of the following standard constants, or other values not listed.

Value Description
E_FAIL Failure.
E_POINTER Null pointer argument.
E_INVALIDARG Invalid argument.
E_NOTIMPL Method is not supported.
S_OK or NOERROR Success.

Remarks

This method sets a logical palette for the window. The window is not guaranteed to always have the colors requested in the actual system device palette. The Microsoft Windows operating system only guarantees those colors when the window is the foreground active window. The current device palette can be obtained by calling IOverlay::GetPalette.

If the device does not have a palette, it returns VFW_E_NO_DISPLAY_PALETTE.

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.
