ICGetDisplayFormat function (vfw.h)
The ICGetDisplayFormat function determines the best format available for displaying a compressed image. The function also opens a compressor if a handle of an open compressor is not specified.
Syntax
HIC VFWAPI ICGetDisplayFormat(
HIC hic,
LPBITMAPINFOHEADER lpbiIn,
LPBITMAPINFOHEADER lpbiOut,
int BitDepth,
int dx,
int dy
);
Parameters
hic
Handle to the compressor to use. Specify NULL to have VCM select and open an appropriate compressor.
lpbiIn
Pointer to BITMAPINFOHEADER structure containing the compressed format.
lpbiOut
Pointer to a buffer to return the decompressed format. The buffer should be large enough for a BITMAPINFOHEADER structure and 256 color entries.
BitDepth
Preferred bit depth, if nonzero.
dx
Width multiplier to stretch the image. If this parameter is zero, that dimension is not stretched.
dy
Height multiplier to stretch the image. If this parameter is zero, that dimension is not stretched.
Return value
Returns a handle to a decompressor if successful or zero otherwise.
