	Quick Info

The ICDecompressOpen macro opens a decompressor that is compatible with the specified formats.

HIC ICDecompressOpen(

DWORD fccType,
DWORD fccHandler,
LPBITMAPINFOHEADER lpbiIn,
LPBITMAPINFOHEADER lpbiOut
);

Parameters
fccType

Four-character code indicating the type of compressor to open. For video streams, the value of this parameter is "VIDC" or ICTYPE_VIDEO.

fccHandler

Four-character code indicating the preferred stream handler to use. Typically, this information is stored in the stream header in an AVI file.

lpbiIn

Address of a structure defining the input format. A decompressor handle is not returned unless it can decompress this format. For bitmaps, this parameter refers to a BITMAPINFOHEADER structure.

lpbiOut

Address of a structure defining an optional decompression format. You can also specify zero to use the default output format associated with the input format.

If this parameter is nonzero, a compressor handle is not returned unless it can create this output format. For bitmaps, this parameter refers to a BITMAPINFOHEADER structure.

Return Values
Returns a handle of a decompressor if successful or zero otherwise.

Remarks
The ICDecompressOpen macro is defined as follows:

#define ICDecompressOpen(fccType, fccHandler, lpbiIn, lpbiOut) \

ICLocate(fccType, fccHandler, lpbiIn, lpbiOut, ICMODE_DECOMPRESS);
