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. * '-c' clips pages to their bounding box: this is set by default, so that any content outside bounding box will be lost. Using "-c 0", anything outside the bounding box will be displayed, and may overlap neighbouring pages. * '-p' can be used to only consider a set of pages of the input file. The set of pages to include is a comma- separated list of pages, ranges of pages of the form 'm-n', or sets of pages of the form "0%2" (all even- numbered pages). Alternatively to '-p', the page range can be specified after the file name, writing 'file.pdf:' in place of '-p '. * '-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 * '-w file' can be used to add watermarking to all pages. The file can be anything that pdflatex can handle (eg. png, pdf). If it is a PDF with several pages, page n of the watermarking file will be used with page n of the input file. By default, the last page will be repeated if the input file has more pages than the watermarking file. This behaviour can be modified with the '-wp n' options, which asks to repeat the last n pages instead of only the last one. Setting `-wp 0` will repeat all the pages of the watermarking file. ################################################################## ## ## Examples ## ################################################################## # pdfxup file.pdf -> creates pdfxup.pdf from file.pdf with default options (2-up, margins=5mm) # pdfxup -bb 1-4 file.pdf -> same behaviour, but computes the bounding box only using the first 4 pages (this saves time when processing long documents) # pdfxup -b file.pdf -> same behaviour, but creates a booklet # pdfxup -kbb -b -o booklet.pdf file.pdf:3-25 -> creates a booklet from pages 3-25 of file.pdf, without reducing margins (option '-kbb' disables bounding-box computation; equivalent to e.g. '-bb 0'); name the resulting file booklet.pdf. # pdfxup -kbb -x1 -y2 -l0 beamer-frames.pdf -> arranges 2 beamer frames per page (not reducing margins) # pdfxup -kbb -x2 -y2 -l1 beamer-frames.pdf -> arranges 4 beamer frames per page (not reducing margins) # pdfxup -fw0 -w draft.png file.pdf -> remove frame border; add 'draft' watermarking on all pages
