No , RAW and EMF is two different type format of print processor .

SPL contains EMF data , if you want get emf ,just need get spl and
extract emf from it


This is not correct. SPL files can hold all sorts of different formats: NT
EMF (a special EMF based spool format), TEXT and RAW. Where RAW stands for
the "raw" job data which is sent to the printer. RAW could be PCL,
PostScript, ESC/P or similar.

You can not just depend on the SPL files to include EMF, this depend on
several factors.

The print processor converts from one format to the next, ending in RAW. And
the data is spooled in the SPL files between stages.
The print processor uses (normally) functions provided by the spooler to
convert from one format to the other.
