The ICDrawRealize macro notifies a rendering driver to realize its drawing palette while drawing. You can use this macro or explicitly call the ICM_DRAW_REALIZE message.
DWORD ICDrawRealize(
hic,
hdc,
fBackground
);
Returns ICERR_OK if the drawing palette is realized or ICERR_UNSUPPORTED if the palette associated with the decompressed data is realized.
Drivers need to respond to this message only if the drawing palette is different from the decompressed palette.
Windows NT: Requires version 3.1 or later.
Windows: Requires Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in vfw.h.
