- Subject: Can ghostcript be used as a simple UNIX filter?

- I have tried to use ghostscript 2.5.2 as a simple UNIX filter for translating
- pictures from PostScript to a supported output language (PCL, pbm, ...).
- Despite numerous attempts with various combinations of the flags -q,
- -sDEVICE, -dNOPAUSE, and -sOUTPUTFILE, I have failed miserably.
-
- What I want is:
-
- (1) To be able to send processed output directy to stdout.
-
- (2) Avoid getting caught inside ghostscript (I don't want to
- see the 'GS>' prompt, ever).
-
- Surely this must be possible or is there a serious design flaw in ghosctript?
-
- The closest I have got is
- gs -q -sDEVICE=ljet3 -r300 -dNOPAUSE -sOUTPUTFILE='|lp -or'
- but it does not give either (1) or (2) above since it prints to |lp -or
- and not to stdout and I still have to type 'quit" at a 'GS>' prompt. This
- is unacceptable in my application where I just want to filter PS data.
-
- Any help much appreciated. Please e-mail.
