ICDecompressOpen
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);
