EMF (Windows Enhanced Metafile)

The EMF file format is the successor to the legacy WMF image format, capable of storing both two-dimensional raster and vector graphics. The WMF format was introduced by Microsoft in 1992 as part of the Windows 3 SDK and has evolved over time with new features until being replaced by the EMF format.

EMF files contain 32-bit data and are similar in nature to SVG files in that they can store both raster and vector image data. The format is used within versions of Microsoft Office and can be opened with a limited number of graphics applications.
