The PDF files created from NCL should comform in all
respects to the format described in Adobe's "PDF
Reference, Third Edition, v1.4." What tool are you
using (that you refer to as the "ordinary method")
that does not correctly extract images?

As Mateus has suggested, working with PostScript
may be easier for this task. To split out individual
PostScript images, you can use the "psplit" application
that is distrbuted with NCL. See:
