3.3.5.1 Drawing Orders

All drawing orders are encapsulated in an Orders Update (section 2.2.2.1), which is sent as part of the Graphics Update PDU (see [MS-RDPBCGR] section 2.2.9.1.1.3); or they are encapsulated in a Fast-Path Orders Update (section 2.2.2.2), which is sent as part of the Fast-Path Update PDU (see [MS-RDPBCGR] section 2.2.9.1.2).

There are three classes of drawing orders:

• Primary Drawing Orders (section 3.2.5.1.1)

• Secondary Drawing Orders (section 2.2.2.2.1.2)

• Alternate Secondary Drawing Orders (section 2.2.2.2.1.3)

Orders belonging to each of these classes are packed together into an Orders Update structure or a Fast-Path Orders Update structure, each order being aligned on a byte boundary.
