NAME

PDF::Imposition - Perl module to manage the PDF imposition

VERSION

Version 0.26

SYNOPSIS

This module is meant to simplify the so-called imposition, i.e., rearrange the pages of a PDF to get it ready to be printed and folded, with more logical pages placed on the sheet, usually (but not exclusively) on recto and verso.

This is what the routine looks like:

    use PDF::Imposition;
    my $imposer = PDF::Imposition->new(file => "test.pdf",
                                       outfile => "out.pdf",
                                       # or # suffix => "-imposed",
                                       signature => "40-80",
                                       cover => 0,
                                       schema => "2up");
    $imposer->impose;
    print "Output left in " . $imposer->outfile;

Please note that you don't pass the PDF dimensions (which are extracted from the source PDF itself by the class, using the very first page: if you want imposition, I do the reasonable assumption you have all the pages with the same dimensions).

METHODS

Costructor options and accessors

file

The input file

outfile

The output file

suffix

The suffix of the output file (don't mix the two options).

schema

The schema to use.

2up

See PDF::Imposition::Schema2up

duplex2up

See PDF::Imposition::Schemaduplex2up

2down

See PDF::Imposition::Schema2down

2x4x1

4up

See PDF::Imposition::Schema4up

1x4x2cutfoldbind

See PDF::Imposition::Schema1x4x2cutfoldbind

1repeat2top

1x1

See PDF::Imposition::Schema1x1

cover

If the last logical page must be placed at the very end, after the blank pages used to pad the signature. (2up, 2down 1x4x2cutfoldbind, 4up, 1x1 only).

Often it happens that we want the last page of the pdf to be the last one on the physical booklet after folding. If cover is set to a true value, the last page of the logical pdf will be placed on the last page of the last signature.

signature

The signature (integer multiple of four or range): 2up and 2down only.

paper

Passing this option triggers the cropmarks. While the original dimensions are left unchanged, this size represents the size of the logical page which is actually imposed.

For example, you have a PDF in a6, you pass a5 as paper, and schema 2up, you are going to get an a4 with 2 a6 with cropmarks.

This option is passed to PDF::Cropmarks. See the module documentation for the accepted values.

title

The title to set in the PDF meta information. Defaults to the basename.

Cropmarks options

The following options are passed verbatim to PDF::Cropmarks. See the module documentation for the meaning and accepted values.

paper_thickness

Defaults to 0.1mm

font_size

Defaults to 8pt

cropmark_offset

Defaults to 1mm

cropmark_length

Defaults to 12mm

impose

Main method which does the actual job. You have to call this to get your file. It returns the output filename.

version

Return the version string.

available_schemas

Called on the class (not on the object returned by new) will report the list of available schema.

E.g.

 PDF::Imposition->available_schemas;

INTERNALS

BUILDARGS
imposer
DEBUG

Constant picked from AMW_DEBUG environment.

The names of schemas are taken straight from the ConTeXt ones (if existing), as described in the book Layouts in context, by Willi Egger, Hans Hagen and Taco Hoekwater, 2011.

TODO

The idea is to provide a wide range of imposition schemas (at least the same provided by ConTeXt). This could require some time. If you want to contribute, feel free to fork the repository and send a pull request or a patch (please include documentation and at some tests).
