nLeftRect (variable): The left coordinate of the destination rectangle specified by using a Coord Field (section 2.2.2.2.1.1.1.1).

nTopRect (variable): The top coordinate of the destination rectangle specified by using a Coord Field (section 2.2.2.2.1.1.1.1).

nWidth (variable): The width of the destination rectangle specified by using a Coord Field (section 2.2.2.2.1.1.1.1).

nHeight (variable): The height of the destination rectangle specified by using a Coord Field (section 2.2.2.2.1.1.1.1).

bRop (1 byte): The index of the ternary raster operation to perform (see section 2.2.2.2.1.1.1.7).

BackColor (3 bytes): The background color described by using a Generic Color (section 2.2.2.2.1.1.1.8) structure.

ForeColor (3 bytes): The foreground color described by using a Generic Color (section 2.2.2.2.1.1.1.8) structure.

BrushOrgX (1 byte): An 8-bit, signed integer. The x-coordinate of the point where the top leftmost pixel of a brush pattern MUST be anchored.

BrushOrgY (1 byte): An 8-bit, signed integer. The y-coordinate of the point where the top leftmost pixel of a brush pattern MUST be anchored.

BrushStyle (1 byte): An 8-bit, unsigned integer. The contents and format of this field are the same as the BrushStyle field of the PatBlt (section 2.2.2.2.1.1.2.3) Primary Drawing Order.

BrushHatch (1 byte): An 8-bit, unsigned integer. The contents and format of this field are the same as the BrushHatch field of the PatBlt (section 2.2.2.2.1.1.2.3) Primary Drawing Order.

BrushExtra (7 bytes): The contents and format of this field are the same as the BrushExtra field of the PatBlt (section 2.2.2.2.1.1.2.3) Primary Drawing Order.

nDeltaEntries (1 byte): An 8-bit, unsigned integer. The number of bounding rectangles described by the CodedDeltaList field.

CodedDeltaList (variable): A Two-Byte Header Variable Field (section 2.2.2.2.1.1.1.3) structure that encapsulates a Delta-Encoded Rectangles (section 2.2.2.2.1.1.1.5) structure that contains bounding rectangles to use when rendering the order. The number of rectangles described by the Delta-Encoded Rectangles structure is specified by the nDeltaEntries field.
