Only two? Heh.
EPS is just plain old PostScript with the Document Structuring
Conventions junk included. The bitmap representation part is
*optional*, and if it is included its format is *unspecified*.
Basically, EPS by itself is next to useless for interchange.
WHY, you ask? I don't know.
However, the EPSF doc (send mail to ps-file-server@adobe.com and ask
for Documents/EPSF.ps) does specify a machine-independent bitmap
representation. This sub-format is called EPSI, and it would be
quite useful if anyone actually used it.
