Meaning
EMRI_METAFILE_EXT
0x0000000D
Offset to a page content record.
EMRI_BW_METAFILE_EXT
0x0000000E
Offset to a page content record that contains only monochrome data.
cjSize (4 bytes): A 32-bit unsigned integer that specifies the size, in bytes, of the data attached to the record. The size of each record in EMF spool format MUST be rounded up to a multiple of 4 bytes.
offset (8 bytes): A 64-bit unsigned integer that specifies the offset, in bytes, from the start of the page offset record to the start of a page content record. That page content record MUST be located ahead of the corresponding page offset record, which means that the offset is counted backward in the metafile.
