ICM_DECOMPRESS

The ICM_DECOMPRESS message is sent to a video compression driver to decompress a frame of data into an application-supplied buffer.

Parameters

dwParam1

Specifies a pointer to an ICDECOMPRESS structure.

dwParam2

Specifies the size of the ICDECOMPRESS structure.

Return Value

Returns ICERR_OK if successful. Otherwise, returns an error number.

Comments

If the driver is to decompress data directly to the screen instead of a buffer, it receives the ICM_DRAW message.

The driver should return an error if this message is received before the ICM_DECOMPRESS_BEGIN message.
