ICDecompressGetFormat macro (vfw.h)

The ICDecompressGetFormat macro requests the output format of the decompressed data from a video decompression driver. You can use this macro or explicitly call the ICM_DECOMPRESS_GET_FORMAT message.

Syntax

void ICDecompressGetFormat(
   hic,
   lpbiInput,
   lpbiOutput
);

Parameters

hic

Handle to a decompressor.

lpbiInput

Pointer to a BITMAPINFO structure containing the input format.

lpbiOutput

Pointer to a BITMAPINFO structure to contain the output format. You can specify zero to request only the size of the output format, as in the ICDecompressGetFormatSize macro.

Return value

None

Remarks

If lpbiOutput is nonzero, the driver should fill the BITMAPINFO structure with the default output format corresponding to the input format specified for lpbiInput. If the compressor can produce several formats, the default format should be the one that preserves the greatest amount of information.
