Free pdf tools software for linux

x2svg is an application to graphically lay out files like DTDs and Java property files as scalable vector graphics (SVG). SVG diagrams can be converted into PDF files directly from within x2svg.

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.

pdfTeX is an extended version of TeX that can create PDF directly from TeX source files and enhance the result of TeX typesetting with the help of PDF.
When PDF output is not selected, pdfTeX produces normal DVI output, otherwise it produces PDF output that looks identical to the DVI output.
An important aspect of pdfTeX project is to investigate alternative justification algorithms, optionally making use of multiple master fonts.
Enhancements:
- This includes xpdf 3.02pl1, fixing some security problems.

Lout project is a document formatting system.

The system reads a high-level description of a document similar in style to LaTeX and produces a PostScript file which can be printed on most laser printers and graphic display devices.

Plain text and PDF (starting from version 3.12) output are also available.

PDF Split and Merge project is an easy-to-use tool that provides functions to split and merge PDF files or subsections of them.

YaHP Converter is a java library that can convert an HTML document into a PDF document.
YaHP is licensed under the LGPL (GNU).
Method Summary
void convertToPdf(java.lang.String content, IHtmlToPdfTransformer.PageSize size, java.util.List hf, java.lang.String urlForBase, java.io.OutputStream out)
Convert the document in content in a PDF file.
void convertToPdf(java.net.URL url, IHtmlToPdfTransformer.PageSize size, java.util.List hf, java.io.OutputStream out)
Convert the document pointed by url in a PDF file.
private java.net.URL copyToTemp(java.net.URL url)
Copy the file pointed to url in the temp directory
private void init()
initialize the classloader, and the transforme.
Enhancements:
- A NPE which occurred if the FOP_TTF_FONT_PATH property is not set was fixed.

PDF::Reuse::Tutorial is a Perl module that will teach you how to produce PDF-files with PDF::Reuse.

In this tutorial I will show some aspects of PDF::Reuse, so you should be able to use it in your own programs. Most important is how to produce and reuse PDF-code, and then if you are interested, you can look at Graphics and JavaScript, so you can to do special things.

Reusing code:

You can take advantage of what has been done before, it is not necessary to start from scratch every time you create a PDF-file. You use old PDF-files as a source for forms, images, fonts and texts. The components are taken as they are, or rearranged, and you add your own texts and you produce new output.
If you dont care too much about the size of your templates, you should make them with a commercial, visual tool, thats most practical; and then you should use PDF::Reuse to mass produce your files. In this tutorial I show in many places how create single files with PDF::Reuse. That is possible, but more of an exception. I do it here to show the technique. You will anyway need it to add texts and graphics to your templates.

Graphics:

With this module you get a good possibility to program directly with the basic graphic operators of PDF. This is perhaps an advanced level, and you can avoid it if you want. On the other hand, it is not very difficult, and if you take advantage of it, your possibilities to manage text and graphics increase very much. You should look at the "PDF-reference manual" which probably is possible to download from http://partners.adobe.com/asn/developer/acrosdk/docs.html. Look especially at chapter 4 and 5, Graphics and Text, and the Operator summary.
Whenever the function prAdd() is used in this tutorial, you can probably get more explanations in the "PDF-reference manual". The code, you add to the content stream with prAdd(), has to follow the PDF syntax completely.

JavaScript:

You can add JavaScript to your PDF-file programmatically. This works with Acrobat Reader 5.0.5 or Acrobat 5.0 and higher versions.

You should have the "Acrobat JavaScript Object Specification" by hand. If you havent got Acrobat, you can probably download it from http://partners.adobe.com/asn/developer/technotes/acrobatpdf.html. It is technical note # 5186. JavaScript for HTML and PDF differs so much that you need the manual, even if you know JavaScript very well.
