WMF in het kort
WMF
The original WMF specification was published in the Windows 3.1 SDK documentation in 1992. Aldus Corporation independently added a 'placeable' header for device independence, which Microsoft later incorporated in Windows 2000. The format specification was republished in 2006 under the Microsoft Open Specification Promise.
