Windows Metafile

Windows Metafile (WMF) is a graphics file format used mainly by old Microsoft Windows applications. It stores a list of commands which, when executed, generate an image.

Windows has drivers to support WMF, allowing applications to either write to a WMF file, or draw on the screen, using the same API.
