1.3.1.1.3 Metafile

A Windows metafile (as specified in [MS-WMF] section 2) is a collection of structures that can store an image in an application-independent format. The stored image can be recreated by processing the metafile structures. Also called a vector image, a metafile contains a sequence of drawing commands and settings. The commands and settings recorded in a metafile object can be rendered on a display, output by a printer or plotter, stored in memory, or saved to a file or stream. Metafile data to be transferred between virtual channel endpoints is specially encoded and decoded for transport on the wire by the Remote Desktop Protocol: Clipboard Virtual Channel Extension.
