ICDecompressSetPalette macro (vfw.h)

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

void 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

None

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.
