Enhanced Metafile

Enhanced Metafile (EMF) is a vector graphics format native to 32-bit versions of Microsoft Windows. It is the successor to Windows Metafile (WMF).

There is an extension of the format, named Enhanced Metafile Format Plus Extensions (EMF+).

The .emz filename extension is reportedly used for gzip-compressed EMF files.

EMF+ files are EMF files with the following characteristics. Let n be the 32-bit integer at offset 4. At offset n is the 32-bit integer 0x00000046 (representing record type EMR_COMMENT). At offset n+12 is the ASCII string "".
