Great. }WHY are there two different formats? 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. --- Jef Jef Poskanzer jef@well.sf.ca.us {ucbvax, apple, hplabs}!well!jef "In America, through pressure of conformity, there is freedom of choice, but nothing to choose from." -- Peter Ustinov
