3.2.5.9.1 Processing Slow-Path Graphics Update PDU

The structure and fields of the Slow-Path Graphics Update PDU are specified in section 2.2.9.1.1.3, and the techniques specified in section 3.2.5.2 demonstrate how to process the contents of the PDU.

The slowPathGraphicsUpdate field contains a single graphics update structure, which MUST be one of the following types:

If a slow-path update structure is received which does not match one of the known types, the client SHOULD ignore the data in the update.

Once this PDU has been processed, the client MUST carry out any operations necessary to complete the update. In the case of a Palette Update, the client MUST update the global palette on all drawing surfaces. Processing of the Bitmap Update requires that the client render the attached bitmap data on the primary drawing surface as specified by the update parameters. The Synchronize Update MAY be ignored by the client. Processing of the Orders Update (which contains Optimized RDP Drawing Orders) is specified in [MS-RDPEGDI] section 3.2.5.
