Members

dwFlags

Applicable flags. The following values are defined:

ICDECOMPRESS_HURRYUP

Tries to decompress at a faster rate. When an application uses this flag, the driver should buffer the decompressed data but not draw the image.

ICDECOMPRESS_NOTKEYFRAME

Current frame is not a key frame.

ICDECOMPRESS_NULLFRAME

Current frame does not contain data and the decompressed image should be left the same.

ICDECOMPRESS_PREROLL

Current frame precedes the point in the movie where playback starts and, therefore, will not be drawn.

ICDECOMPRESS_UPDATE

Screen is being updated or refreshed.

lpbiSrc

Address of a BITMAPINFOHEADER structure containing the input format.

lpSrc

Address of a buffer containing the input data.

lpbiDst

Address of a BITMAPINFOHEADER structure containing the output format.

lpDst

Address of a buffer where the driver should write the decompressed image.

xDst, yDst

The x- and y-coordinates of the destination rectangle within the DIB specified by lpbiDst.

dxDst, dyDst

Width and height of the destination rectangle.

xSrc, ySrc

The x- and y-coordinates of the source rectangle within the DIB specified by lpbiSrc.

dxSrc, dySrc

Width and height of the source rectangle.
