Signature (4 bytes): 0x464D4520 specifies the record signature, which consists of the ASCII string "EMF".
Version (4 bytes): 0x00010000 specifies EMF metafile interoperability.
Bytes (4 bytes): 0x00000764 specifies the size of the metafile in bytes.
Records (4 bytes): 0x00000021 specifies the number of records in the metafile.
Handles (2 bytes): 0x0002 specifies the number of indexes that will need to be defined during the processing of the metafile. These indexes correspond to graphics objects that are used in drawing commands. Index 0 is reserved for references to the metafile itself.
Reserved (2 bytes): 0x0000 is not used.
nDescription (4 bytes): 0x0000000C specifies the number of characters in the array that contains the description of the EMF metafile's contents.
offDescription (4 bytes): 0x0000006C specifies the offset from the beginning of this record to the array that contains the description of the EMF metafile's contents.
nPalEntries (4 bytes): 0x00000000 specifies the number of entries in the metafile palette. The location of the palette is specified in the EMF end-of-file record.
