pdfxup creates a PDF document where each page is obtained by
combining several pages of a PDF file given as output. The
important feature of pdfxup, compared to similar programs,
is that it tries to compute the (global) bounding box of the
input PDF file, in order to remove the margins and to keep
the text only. Instead of having the font size divided by 2
(for the case of 2-up output), in some case you may end up
with the same font size as in the original document (as is
the case for a default 'article' document produced by LaTeX).
pdfxup has numerous options:
* '-x n' and '-y n' can be used to change the number of
rows and columns of the resulting document.
[default: -x2 -y1]
* '-l n' turns the output to landscape (n=1) or portrait
(n=0).
[default: -l1]
* '-b n' toggles the 'booklet' mode: the resulting PDF can
be printed and folded as a booklet. Printing such a
booklet requires 2-sided printing, which can follow
either the 'long-edge' or the 'short edge' of the paper.
'long-edge' seems to be the most commonly used, but using
'-b se' while produce a PDF booklet for 'short-edge'
2-sided printing.
* '-p' can be used to only consider a range of pages of the
input file. We do not handle unions of page ranges, so that
only the last occurrence of '-p' will be used. The
restriction applies both for the computation of the
bounding box (and is compatible with the options '-bb' and
'-nobb' below) and for creating the final document.
Alternatively to '-p', the page range can be specified
after the file name, writing 'file.pdf:n-m' in place of
'-p n-m'.
* '-bb' can be used to list the pages to be taken into
account when computing the bounding box. This is
especially useful for large documents, because computing the
bounding box on each page can be long, and because
computing the bounding box over the first 10 pages is
usually enough... This will not change the number of pages
included in the final document.
Several '-bb' options can be given, which will result in
considering the union of all the intervals.
* '-nobb' is used to remove pages from the computation of
the bounding box. This is useful if one page has e.g.
special headers (e.g. for arXiv papers). Notice that the
bounding box of those pages will still be computed by
ghostscript, so this does not save time. I'd be grateful
to anyone willing to implement difference of unions of
intervals... ;-)
* '-fw d' defines the width of the frame around each page.
Set to 0pt to have no frame at all.
* inner margins: margins to be added between each frame and
its included page.
* margins: margins of the final document
* spacing: spacing between frames
