Detailed Description

For U_EMR* dwROP fields. Microsoft name: Ternary Raster Operation enumeration WMF manual 2.1.1.31

These codes specify:

an order of operands (composed of various orders and combinations of: Dest, Src, Pen) (There are 3, hence "Ternary Raster Operation")
an order of operators to apply to the operands (composed of Not, Xor, Or, And) Only a few of the more common operations are provided here. When the Operation does not use a Src operand the corresponding source bitmap may be omitted from the record.
