ICM_DECOMPRESSEX message
The ICM_DECOMPRESSEX message notifies a video compression driver to decompress a frame of data directly to the screen, decompress to an upside-down DIB, or decompress images described with source and destination rectangles.
ICM_DECOMPRESSEX
wParam = (DWORD_PTR) (LPVOID) &icdex;
lParam = sizeof(ICDECOMPRESSEX);
Parameters
- icdex
-
Pointer to an ICDECOMPRESSEX structure.
- lParam
-
Size, in bytes, of ICDECOMPRESSEX.
Return Value
Returns ICERR_OK if successful or an error otherwise.
Remarks
This message is similar to ICM_DECOMPRESS except that it uses the ICDECOMPRESSEX structure to define its decompression information.
If you want the driver to decompress data directly to the screen, send the ICM_DRAW message.
The driver returns an error if this message is received before the ICM_DECOMPRESSEX_BEGIN message.
