Parameters
hic
Handle of the
decompressor to use.
dwFlags
Reserved; do
not use.
lpbiSrc
Address of a BITMAPINFOHEADER structure containing the
format of the compressed data to decompress.
lpSrc
Reserved;
must be NULL.
xSrc,
ySrc
The x- and
y-coordinates of the source rectangle for the DIB specified by lpbiSrc.
dxSrc,
dySrc
Width and
height of the source rectangle.
lpbiDst
Address of 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
Address of a
buffer that is large enough to contain the decompressed data.
xDst,
yDst
The x- and
y-coordinates of the destination rectangle for the DIB specified by lpbiDst.
dxDst,
dyDst
Width and
height of the destination rectangle.
Return Values
Returns
ICERR_OK if successful or an error otherwise.
