Windows Metafile
Windows Metafile (
WMF) is a common
graphics file format on
Microsoft Windows systems. It is a
vector graphics format which also allows to include
raster graphics. Essentially, a WMF file stores a list of commands that have to be issued to the Windows graphics layer in order to restore the image.
WMF is a 16-bit format; a newer 32-bit version with additional commands is called Enhanced Metafile (EMF).
