ICDecompressExQuery function (vfw.h)
The ICDecompressExQuery function determines if a decompressor can decompress data with a specific format.
Syntax
LRESULT VFWAPI_INLINE ICDecompressExQuery(
HIC hic,
DWORD dwFlags,
LPBITMAPINFOHEADER lpbiSrc,
LPVOID lpSrc,
int xSrc,
int ySrc,
int dxSrc,
int dySrc,
LPBITMAPINFOHEADER lpbiDst,
LPVOID lpDst,
int xDst,
int yDst,
int dxDst,
int dyDst
);
Parameters
hic
Handle to the decompressor to use.
dwFlags
Reserved; do not use.
lpbiSrc
Pointer to a BITMAPINFOHEADER structure containing the format of the compressed data to decompress.
lpSrc
Reserved; must be NULL.
xSrc
The x-coordinate of the source rectangle for the DIB specified by lpbiSrc.
ySrc
The y-coordinate of the source rectangle for the DIB specified by lpbiSrc.
dxSrc
Width of the source rectangle.
dySrc
Height of the source rectangle.
lpbiDst
Pointer to a BITMAPINFOHEADER structure containing the output format. If the value of this parameter is NULL, the function determines whether the input format is supported and this parameter is ignored.
lpDst
Pointer to a buffer that is large enough to contain the decompressed data.
xDst
The x-coordinate of the destination rectangle for the DIB specified by lpbiDst.
yDst
The y-coordinate of the destination rectangle for the DIB specified by lpbiDst.
dxDst
Width of the destination rectangle.
dyDst
Height of the destination rectangle.
Return value
Returns ICERR_OK if successful or an error otherwise.
