Splitting 2 pages/page landscape postscript file into two single page portrait pages

Splitting 2 pages/page landscape postscript file into two single page portrait pages

[vasan999]

Hi, I am a newbie.

I have a book.ps file which has all the pages, having two facing pages
per portrait page like this:

+---------------+--------------+
|                 |               |
|                 |               |
+---------------+--------------+

I want to split the two pages. I dont want to scan the pages and then
make bulky images out of compact pdf file. The file was generated from
a dvi and latex that are no longer available. The
author has died. The ps was made to save the number of printed
pages in an era before pdf.

So there are two problems:
(1) split the ps into single pages
(2) split each page in the center to to two successive pages.
(3) then combine all the ps
(4) I would like the ps to be converted to pdf so that it is
searcheable, if possible.

Steps 1-2 are the most important.

Could you please post (an URL to) a sample of that file
(the first 2 or 3 pages would be sufficient). If steps 1 and
2 can be done and, if yes, which what effort, can only be estimated
after looking into the file.

Do you have access to Adobe Acrobat? (If not, download the trial
version for 30 days...)

1) Open your document with pdf distiller. It will create a pdf out of
the ps file.
2) Crop the pages so that you get even pages showing.
3) Print that file TO THE PDF PRINTER (sorry the caps but I want to
make the point)
4) Open the generated pdf and export all pages.
5) Rename (use a dos batch file) those pages to something that shows
their being even.
6) Repeat for odd pages.
7) Create pdf from the exported pages.
8) Send me a postcard.

PS. I know it works because I use this method (minus the even/odd) to
get rid of footnotes/magin notes and I still get a searchable pdf.

You could convert it to pdf and then use pdfpages to split the pages
in two and then collate using this file
http://www.jmilne.org/math/Books/two2one.tex
However, I don't know whether this preserves the embedded fonts etc.
(the file is intended for scanned pages).

I can't help but think that all the solutions proposed so far are
overthinking the problem. There are only a few good ways to 2-up a
document in postscript, and it seems likely that a suitable perl
script (or, if you're insane like Don Lancaster, a postscript program)
could do the job without having to go through a PDF phase.

It's easy to think this because you're correct.  It would be nice to see
the first few pages, as was requested, simply so we could discern what
2-upper was used.  If the document was created through a reasonable
process like latex->dvips->psnup, then the data should nicely be in
unmunged form whence all that is required is to remove the two-up stuff,
which is easily found after the %%EndSetup as the PStoPS stuff.  In this
case, the pages are preserved (TeXDict begin ... bop ... eop end) so
removing the PStoPS rotation/scaling is all that's required.

Incidentally, I'm sure it would be fairly easy to right a postscript
header that would disable the PStoPS commands and create the same
effect.  :)

It seems to me that going through PDf, etc., is way overkill, and likely
to cause more problems.  The ability to search PDf is, of course,
somewhat dependent on the fonts used; the more steps you carry out, the
more likely it is that it becomes bitmapped.

If you just want to search, I suggest ps2ascii or a more capable
document (postscript) viewer.

Hi

I think a ghostsript mail list is more appropriate for this
discussion.

Anyway, you may wish to try pdftk. If you have ghostscript, first,
convert ps to pdf with ps2pdf, then use pdftk.
