The MAKEROP4 macro creates a quaternary raster operation code for use with the MaskBlt function. The macro takes two ternary raster operation 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. The low-order word of this value will be ignored.

DWORD MAKEROP4(

DWORD fore,	// foreground ternary raster operation code
DWORD back	// background ternary raster operation code
);

Parameters
fore

Specifies a foreground ternary raster operation code.

back
Specifies a background ternary raster operation code

Return Values
The return value is a DWORD quaternary raster operation code for use with the MaskBlt function.

Remarks
The MAKEROP4 macro is defined as follows:

#define MAKEROP4(fore,back)

(DWORD)((((back) << 8) & 0xFF000000) | (fore))
