The ICDecompressSetPalette macro specifies a palette for a video decompression driver to use if it is decompressing to a format that uses a palette. You can use this macro or explicitly call the ICM_DECOMPRESS_SET_PALETTE message.
Syntax
DWORD ICDecompressSetPalette(
hic,
lpbiPalette
);
Parameters
hic
Handle to a decompressor.
lpbiPalette
Pointer to a BITMAPINFOHEADER structure whose color table contains the colors that should be used if possible. You can specify zero to use the default set of output colors.
Return value
Type: DWORD
Returns ICERR_OK if the decompression driver can precisely decompress images to the suggested palette using the set of colors as they are arranged in the palette. Returns ICERR_UNSUPPORTED otherwise.
Remarks
This macro should not affect decompression already in progress; rather, colors passed using this message should be returned in response to future ICDecompressGetFormat and ICDecompressGetPalette macros. Colors are sent back to the decompression driver in a future ICDecompressBegin macro.
This macro is used primarily when a driver decompresses images to the screen and another application that uses a palette is in the foreground, forcing the decompression driver to adapt to a foreign set of colors.
