2.3.5 Drawing Record Types

  • [アーティクル]

The Drawing record types perform graphics drawing and painting functions. The clipping regions used by drawing records are maintained in the Regions state element (section 3.1.1.2.1) in the playback device context (section 3.1).

The following are EMF drawing record types.
