(Set ROP2)

Mnemonic: (SetROP2 = Mode)
Discussion: Sets the current foreground mix mode. GDI uses the foreground mix mode to combine pens and interiors of filled objects with the colors already on the screen. The foreground mix mode defines how colors from the brush or pen and the colors in the existing image are to be combined.

Where Mode can be any of the following values:

R2.COPYPEN = 13 Pixel is the pen color.
R2.MASKNOTPEN = 3 Pixel is a combination of the colors common to both the screen and the inverse of the pen.
R2.MASKPEN = 9 Pixel is a combination of the colors common to both the pen and the screen.
R2.MASKPENNOT = 5 Pixel is a combination of the colors common to both the pen and the inverse of the screen.
R2.MERGENOTPEN = 12 Pixel is a combination of the screen color and the inverse of the pen color.
R2.MERGEPEN = 15 Pixel is a combination of the pen color and the screen color.

R2.NOT = 6 Pixel is the inverse of the screen color.
R2.NOTCOPYPEN = 4 Pixel is the inverse of the pen color.
R2.NOTMASKPEN = 8 Pixel is the inverse of the R2_MASKPEN color.
