3.3.5.1.1.1.22 Construction of MultiDrawNineGrid
The structure and fields of the MultiDrawNineGrid Primary Drawing Order are specified in section 2.2.2.2.1.1.2.22. The order fields MUST be populated in accordance with this description and the instructions detailed in section 3.3.5.1.1.1.
The construction of the MultiDrawNineGrid Order follows the same principles as those outlined for the DrawNineGrid order specified in section 3.3.5.1.1.1.21. However, the MultiDrawNineGrid includes multiple clipping rectangles, as opposed to the DrawNineGrid Order, which only includes one clipping rectangle.
The MultiDrawNineGrid Order MUST NOT be sent to the client if support for it was not specified in the Order Capability Set (see [MS-RDPBCGR] section 2.2.7.1.3).
