I have a PostScript program used to generate PDFs. When such PDFs are viewed two-pages-at-a-time, side-by-side, I want page 1 to be opposite page 2, rather than the usual behaviour of page 1 alone and page 2 opposite 3.

Presumably if there is a way to specify this in the PDF, that specification could be passed to the PDF from PostScript by mark … pdfmark.

¿Please, is there a way for a PDF to require that page 1 is to be shown opposite page 2?

For those interested, link to program and its manual: http://www.jdawiseman.com/papers/placemat/placemat.ps http://www.jdawiseman.com/papers/placemat/placemat.html

No, this is not specified in the PDF (I think).
It's an artifact of your viewer.
See if there is an option for "two-page view without cover"
(It think p.1 is the cover of a booklet).

Thank you for the reply, confirming my (less knowledgeable) suspicion.

I would suggest prepending a blank page 0 to your page-set.

(You can get pdftk to do such prepending for you, given a blank PDF page.)

Then the viewer will treat that blank page as the start page, to be
displayed by itself, and will treat your pages 1 and 2 as its second and
third pages, to be shown facing, etc. HTH. Cheers, -- tlvp

Ick! That’s damaging a bigger thing to hack a smaller thing.

But illuminating, in that if that is the best solution then there really isn’t a proper solution.

Thank you. That’s what I wanted.

(Except that it’s ignored by Apple Preview {growl}, but that’s Apple Preview.)

Is there any disadvantage to choosing the first?

No, but there is a difference between the two. The 1st is ‘continuous view’, that is one can scroll to see the bottom of a 2-page spread and the top of the next. With the 2nd the scroll ‘jumps’ at page boundaries (or 2-page spreads in this case).
