After all, isn't PostScript just a bunch >of primitive drawing commands, like "draw a filled rectangle"? No. PostScript is a programming language. It has "for" loops. It has "ifelse" statements. It has file I/O commands. It is Turing complete. You can write a translator, but it becomes a PostScript language interpreter. This issue is not unique to NeXT; it is inherent in the PostScript language upon which the NeXT is based. EPS files on a Mac or PC, by contrast, aren't even DISPLAYABLE, let alone editable. You have to have an extra bitmap picture of the same thing in order to see it on the screen. -- Glenn Reid RightBrain Software glenn@heaven.woodside.ca.us PostScript/NeXT developers ..{adobe,next}!heaven!glenn 415-851-1785
