+
+ bbox The coordinates of a rectangle that tightly

+
+ inch The number of metafile units to the inch. To
+ avoid numeric overflow in PageMaker, this value
+ should be less than 1440.
+
+ reserved A reserved double word. Must be zero.
+
+ checksum A checksum of the 10 words that precede it,
+ calculated by XORing zero with these 10 words
+ and putting the result in the checksum field.
+
+ metafileData The actual content of the Windows metafile
+ retrieved by copying the data returned by
+ GetMetafileBits to the file. The number of
+ bytes should be equal to the MS-DOS file length
+ minus 22. The content of a PageMaker placeable
+ metafile cannot currently exceed 64K (this may
