I have a set of .eps files that I convert to .pdf using epstopdf --gsopt="-dPDFX=true" in order to ensure that all referenced fonts in the eps file are embedded in a portable way. I then want to import the pdf files into my swp file so that I can generate a pdf. This should be easy because pdflatex supports pdf graphics - but there seems to be no way to import using the import picture command. If I directly import the .eps files the pdf that is generated does not embed the fonts used in the eps files.

whats the best method to use?
