Ubuntu Manpage: pdfposter - Scale and tile PDF images/pages to print on multiple pages.

NAME

       pdfposter - Scale and tile PDF images/pages to print on multiple pages.

SYNOPSIS

       pdfposter <options> infile outfile

DESCRIPTION

       Pdfposter can be used to create a large poster by building it from multple pages and/or printing it on
       large media. It expects as input a PDF file, normally printing on a single page. The output is again a
       PDF file, maybe containing multiple pages together building the poster.  The input page will be scaled to
       obtain the desired size.

       The program uses a simple but efficient method which is possible with PDF: All new pages share the same
       data stream of the scaled page. Thus resulting file grows moderatly.

       To control its operation, you need to specify either the size of the desired poster or a scale factor for
       the image:

       • Given  the  poster size, it calculates the required number of sheets to print on, and from that a scale
         factor to fill these sheets optimally with the input image.

       • Given a scale factor, it derives the required number of pages from the input image size, and  positions
         the scaled image centered on this area.

OPTIONS

General Options
--version
Show program's version number and exit

-h, --help
Show help message and exit

--help-media-names
List available media and distance names and exit

-v, --verbose
Be verbose. Tell about scaling, rotation and number of pages. Can be used more than once to
increase the verbosity.

-n, --dry-run
Show what would have been done, but do not generate files.

-A, --art-box
Use the content area defined by the ArtBox (default: use the area defined by the TrimBox)

Defining Output
-m BOX, --media-size=BOX
Specify the desired media size to print on. See below for BOX. The default is A4 in the standard
package.

-p BOX, --poster-size=BOX
Specify the poster size. See below for BOX. pdfposter will autonomously choose scaling and
rotation to best fit the input onto the poster (see EXAMPLES below).

If you give neither the -s nor the -p option, the default poster size is identical to the media
size.

-s NUMBER
Specify a linear scaling factor to produce the poster. Together with the input image size and
optional margins, this induces an output poster size. So don't specify both -s and -p.

Default is deriving the scale factor to fit a given poster size.

Box Definition
The BOX mentioned above is a specification of horizontal and vertical size. The syntax is as follows
(with multipier being specified optionally):
box = [ multiplier ] unit

multiplier = number "x" number

unit = medianame or distancename

Many international media names are recognised by the program, in upper and lower case, and can be
shortened to their first few characters, as long as unique. For instance 'A0', 'Let'. Distance names are
like 'cm', 'inch', 'ft'.

Medias are typically not quadratic but rectangular, which means width and hight differ. Thus using
medianames is a bit tricky:

10x20cm
obviuos: 10 cm x 20 cm (portrait)

20x10cm
same as 10x20cm, since all boxes are rotated to portrait format

Now when using medianames it gets tricky:

1x1a4 same as approx. 21x29cm (21 cm x 29 cm, portrait)

1x2a4 same as approx. 21x58cm (21 cm x 58 cm, portrait)

This are two a4 pages put together at the small side: One portrait page wide and two portrait
pages high.

2x1a4 same as approx. 42x29cm, which is rotated to portrait and is the same a 29x42cm (29 cm x 42 cm)

This are two a4 pages put together at the long side: Two portrait pages wide and one portrait page
high.

EXAMPLES

       pdfposter -mA3 -pA0 a4.pdf out.pdf
              Prints an A4 input file on 8 A3 pages, forming an A0 poster.

       pdfposter -p3x3Let a4.pdf out.pdf
              Prints an inputfile on a poster of 3x3 Letter pages.

       pdfposter -mA0 input.pdf out.pdf
              Enlarges an inputfile to print on a large-media A0 capable device.

       pdfposter -s4 input.pdf out.pdf
              Enlarge  an  inputfile exactly 4 times, print on the default A4 media, and let pdfposter determine
              the number of pages required.

       pdfposter -m10x10cm -pa0 a4.pdf out.pdf
              Just to show how efficient pdfposter is: This will create a file containing 192 pages, but only 15
              times as big as the single page.  With a4.pdf being a quite empty page, this ratio should be  even
              better for filled pages.

       More        examples        including       sample       pictures       can       be       found       at

   Examples for automatic scaling
       • For printing 2 portrait A4 pages high (approx. 58cm) and let  pdfposter  determine  how  many  portrait
         pages wide, specify a lage number of vertical pages. eg:

            pdfposter -p999x2a4 testpage-wide.pdf out.pdf

       • For  printing  2  landscape A4 pages high (approx. 20cm) and let pdfposter determine how many landscape
         pages wide, specify a lage number of horizontal pages. eg:

            pdfposter -p2x999a4 testpage-wide.pdf out.pdf
