MAKEROP4

  • Article

This macro creates a quaternary raster operation (ROP) code for use by the MaskBlt function. 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. For more information, see Ternary Raster Operations.

DWORD MAKEROP4(
  DWORD fore, 
  DWORD back
);

Parameters

  • fore

Return Values
