IDirectDraw7::CreatePalette method (ddraw.h)
Creates a DirectDrawPalette object for this DirectDraw object.
HRESULT CreatePalette( [in] DWORD unnamedParam1, [in] LPPALETTEENTRY unnamedParam2, [out] LPDIRECTDRAWPALETTE *unnamedParam3, [in] IUnknown *unnamedParam4 );
This value consists of one or more of the following flags:
The index is 1 bit. There are two entries in the color table.
The index is 2 bits. There are four entries in the color table.
The index is 4 bits. There are 16 entries in the color table.
The index is 8 bits. There are 256 entries in the color table.
The index refers to an 8-bit color index. This flag is valid only when used with the DDPCAPS_1BIT, DDPCAPS_2BIT, or DDPCAPS_4BIT flag, and when the target surface is 8 bpp. Each color entry is 1 byte long and is an index to a destination surface's 8-bpp palette.
The peFlags member of the associated PALETTEENTRY structure is to be interpreted as a single 8-bit alpha value (in addition to the peRed, peGreen, and peBlue members). A palette created by using this flag can be attached only to a texture: a surface created with the DDSCAPS_TEXTURE capability flag.
This palette can have all 256 entries defined.
Obsolete. DirectDraw always initializes this palette with the colors in the color array passed at lpDDColorArray.
This palette is attached to the primary surface. Changing this palette's color table immediately affects the display unless DDPSETPAL_VSYNC is specified and supported.
This palette is the one attached to the left-eye primary surface. Changing this palette's color table immediately affects the left-eye display unless DDPSETPAL_VSYNC is specified and supported.
This palette can have modifications to it synchronized with the monitor's refresh rate.
Address of an array of 2, 4, 16, or 256 PALETTEENTRY structures to initialize the DirectDrawPalette object.
Address of a variable to be set to a valid IDirectDrawPalette interface pointer if the call succeeds.
Allows for future compatibility with COM aggregation features. Currently, this method returns an error if this parameter is not NULL.
If the method succeeds, the return value is DD_OK.
If it fails, the method can return one of the following error values:
