This macro creates a quaternary raster operation (ROP) code for use by the MaskBltfunction. The macro takes two ternary ROP codes as input, one for the foreground and one for the background, and packs their Boolean operation indexes into the high-order word of a 32-bit value. MAKEROP4 ignores the low-order word.
DWORD MAKEROP4( DWORD fore , DWORD back );
Parameters
- fore
- Specifies a foreground ternary raster operation code.
- back
- Specifies a background ternary raster operation code
Return Values
The return value is a DWORDquaternary raster operation code for use with the MaskBltfunction.
Remarks

#define MAKEROP4(fore,back) (DWORD)((((back) << 8) & 0xFF000000) | (fore))
