[comp.sys.next] Editing PostScript files on NeXT

cape@npdiss1.StPaul.NCR.COM (Robert Cape) (08/25/90)

I understand that the NeXT uses Display PostScript.  If that's so, are there
any tools available for the NeXT that would allow me to pull in PostScript or
Encapsulated PostScript files, edit them, and write out a new PS or EPS file?

What I have in mind is this:
 1) A number of different groups would use EPS files for graphics in their
    documents.
 2) Many of these graphics might contain text (call-outs, labels, etc.).
 3) One group might want 90% of a particular graphic created by another.
 4) Another group might want to translate a publication and the EPS graphics
    text into another language (eg., English --> German).
 5) The generation of the original PS or EPS could be on a variety of
    machines using different software.  (Some might be hand-written PS)

Is this PostScript -> Display PostScript -> edit -> PostScript process
possible today on a NeXT?

If so, I'd appreciate any details on what tools are needed.

Thanks,

Bob Cape

   If I understand you correctly, you want to take PostScript code, 
tweak or edit it a little interactively while displaying it to make
sure it still works, and be able to send the edited PS file somewhere
when you're done. If so, yes, the NeXT is pretty ideal. One of the supplied
demos (named 'Yap') is basically an editor connected to a scrollable
window; press a button and the PS is reimaged in the window. You can
save, clip&paste, etc. as you could with any text editor. Or you could
edit with a different editor and use the PostScript previewer instead;
I'm not sure whether this would have any advantadges (I use Yap when
I'm drawing my own figures and diagrams, myself...)  
   Thing is, the PostScript interpreter (Display PS, but DPS is only
an extension to PS) is part of the OS, so it's trivial to write a 
PostScript previewer (Yap is a pretty short program...)
