PDF::Reuse::Barcode is a Perl module that can create barcodes for PDF documents with PDF::Reuse.

SYNOPSIS

use PDF::Reuse;
use PDF::Reuse::Barcode;
use strict;

prFile(bars.pdf);

PDF::Reuse::Barcode::ITF (x => 70,
y => 530,
value => 0123456789,
prolong => 2.96);

prEnd();

This is a sub-module to PDF::Reuse. It creates barcode "images" to be used in PDF documents. It uses GD::Barcode and its sub-modules: GD::Barcode::Code39, COOP2of5, EAN13 and so on, to calculate the barcode pattern. For Code128 it uses Barcode::Code128.
Normally the barcodes are displayed on a white background and with the characters under the bars.

You can rotate the "image", make it smaller or bigger, prolong the bars and change the background. (But then, dont forget to test that your barcode scanner still understands it.)
If you dont change the size of the "image", the bars are approximately 24 pixels high (the guard bars a few pixels longer) and the box/background is 38 pixels high and something like 20 pixels wider than the barcodes. The text under the bars are 10 pixels high.

The barcodes are generated using a Type3 font by default. Ghostscript and xpdf donthave support for Type3 fonts. If you want to target engines that dont handle Type3 fonts properly, see the "mode" parameter.

Template::Tools::ttree module can process entire directory trees of templates.

SYNOPSIS
ttree [options] [files]

The ttree script is used to process entire directory trees containing template files. The resulting output from processing each file is then written to a corresponding file in a destination directory. The script compares the modification times of source and destination files (where they already exist) and processes only those files that have been modified. In other words, it is the equivalent of make for the Template Toolkit.

It supports a number of options which can be used to configure behaviour, define locations and set Template Toolkit options. The script first reads the .ttreerc configuration file in the HOME directory, or an alternative file specified in the TTREERC environment variable. Then, it processes any command line arguments, including any additional configuration files specified via the -f (file) option.

The .ttreerc Configuration File

When you run ttree for the first time it will ask you if you want it to create a .ttreerc file for you. This will be created in your home directory.

$ ttree

Do you want me to create a sample .ttreerc file for you?

(file: /home/abw/.ttreerc) [y/n]: y
/home/abw/.ttreerc created. Please edit accordingly and re-run ttree

The purpose of this file is to set any global configuration options that you want applied every time ttree is run. For example, you can use the ignore and copy option to provide regular expressions that specify which files should be ignored and which should be copied rather than being processed as templates. You may also want to set flags like verbose and recurse according to your preference.

A minimal .ttreerc:

# ignore these files
ignore = b(CVS|RCS)b
ignore = ^#
ignore = ~$

# copy these files
copy = .(gif|png|jpg|pdf)$

# recurse into directories
recurse

# provide info about whats going on
verbose

In most cases, youll want to create a different ttree configuration file for each project youre working on. The cfg option allows you to specify a directory where ttree can find further configuration files.

cfg = /home/abw/.ttree

The -f command line option can be used to specify which configuration file should be used. You can specify a filename using an absolute or relative path:

$ ttree -f /home/abw/web/example/etc/ttree.cfg
$ ttree -f ./etc/ttree.cfg
$ ttree -f ../etc/ttree.cfg

If the configuration file does not begin with / or . or something that looks like a MS-DOS absolute path (e.g. C:etcttree.cfg) then ttree will look for it in the directory specified by the cfg option.

$ ttree -f test1 # /home/abw/.ttree/test1

The cfg option can only be used in the .ttreerc file. All the other options can be used in the .ttreerc or any other ttree configuration file. They can all also be specified as command line options.

Remember that .ttreerc is always processed before any configuration file specified with the -f option. Certain options like lib can be used any number of times and accumulate their values.

For example, consider the following configuration files:
/home/abw/.ttreerc:

cfg = /home/abw/.ttree
lib = /usr/local/tt2/templates

/home/abw/.ttree/myconfig:

lib = /home/abw/web/example/templates/lib

When ttree is invoked as follows:

$ ttree -f myconfig

the lib option will be set to the following directories:

/usr/local/tt2/templates
/home/abw/web/example/templates/lib

Any templates located under /usr/local/tt2/templates will be used in preference to those located under /home/abw/web/example/templates/lib. This may be what you want, but then again, it might not. For this reason, it is good practice to keep the .ttreerc as simple as possible and use different configuration files for each ttree project.

Creates indexed pdf documents from text files. Designed to aid creating an electronic distribution method for legacy system reports, since many mainframe type print spools are plain text.
Allows indexing, customizing page settings, font size, font face, and super-imposing text over an image in the case of using pre-printed forms. Supports unlimited levels of indexing bookmarks in documents and system/user configuration files.
Suitable for use in an intranet gateway for generating PDF documents in real-time.
Enhancements:
- This fixes a bug for page breaking when the number of lines is a multiple of the lines per page, thanks to Carlo Benna

PDF::Reuse is a Perl module that can reuse and mass produce PDF documents.

SYNOPSIS

use PDF::Reuse;
prFile(myFile.pdf);
prText(100, 500, Hello World !);
prEnd();

This module could be used when you want to mass produce similar (but not identical) PDF documents and reuse templates, JavaScripts and some other components. It is functional to be fast, and to give your programs capacity to produce many pages per second and very big PDF documents if necessary.

The module produces PDF-1.4 files. Some features of PDF-1.5, like "object streams" and "cross reference streams", are supported, but only at an experimental level. More testing is needed. (If you get problems with a new document from Acrobat 6 or 7, try to save it or recreate it as a PDF-1.4 document first, before using it together with this module.)

Templates

Use your favorite program, probably a commercial visual tool, to produce single PDF-files to be used as templates, and then use this module to mass produce files from them.

(If you want small PDF-files or want special graphics, you can use this module also, but visual tools are often most practical.)

Lists

The module uses "XObjects" extensively. This is a format that makes it possible create big lists, which are compact at the same time.

PDF-operators

The module gives you a good possibility to program at a "low level" with the basic graphic operators of PDF, if that is what you want to do. You can build your own libraries of low level routines, with PDF-directives "controlled" by Perl.

Archive-format

If you want, you get your new documents logged in a format suitable for archiving or transfer.

PDF::Reuse::Tutorial might show you best what you can do with this module.

JavaScript

You can attach JavaScripts to your PDF-files.

You can have libraries of JavaScripts. No cutting or pasting, and those who include the scripts in documents only need to know how to initiate them. (Of course those who write the scripts have to know Acrobat JavaScript well.)

PdfRipImage is a utility to extract images from PDF documents and convert them to a format of your choice. You can choose to extract whole pages or just the images contained in them.

The program is available as a GNOME graphical version.

PDF::ReportWriter is a Perl module that produces high-quality PDF reports from a report definition and a data array.

PDF::ReportWriter supports text formatting and alignment, unlimited grouping with group functions, intelligent page breaking, image support, color support, shaped cell backgrounds, and numeric formatting.
