--help
Prints usage details and exits.

--doc
Displays full documentation and exits.

--version
Prints version number and exits.

--title
Sets the title to be included in the page header. If unspecified, the title will default to the name of the file which is being converted, or to STDIN if a2pdf is processing from standard input.

--timestamp
Boolean option - if set, the timestamp of the file to be converted will be included in the page header. This option is turned off by default.

--icon
Path to an image file which will be included as part of the header in the top left of each page. Image files may be in any format supported by PDF::API2.

--icon-scale
Scaling value for icon images, default is 0.25.

--header | --noheader | --notitle
Prints a header consististing of the page title, and optionally the timestamp and an image icon at the top of each page. This option is enabled by default, use "--notitle" or "--noheader" to disable.

--footer | --nofooter | --page-numbers | --nopage_numbers
Adds the current page number to the bottom of each page. This is enabled by default, use --nofooter or --nopage-numbers to disable.

--line-numbers | --noline-numbers
By default, line numbers will be included in the output PDF file. To disable this behaviour, use the --noline-numbers option.

--perl-syntax | --noperl-syntax
Enables or disables (default is enabled) Perl syntax highlighting. This feature requires that the Perl::Tidy module is installed.

--page-height
Page height in points. Default is 842 (A4).

--page-width
Page with in points. Default is 595 (A4).

--margins
--left-margin
--right-margin
--top-margin
--bottom-margin
Specifies the non-printable area of the page. The margin option will set all margins to the same value, however individual margins may be altered with the appropriate options. Values must be given in points. The default value for all margins is 48 points (0.75").

--font-face
Sets the font to use for the PDF file - currently this must be one of the PDF core fonts. The default font face is Courier.

--font-size
Font size in points, default value is 10.

--line-spacing
Line spacing in points, default value is the font size + 2.

--noformfeed
By default, any formfeed characters in the input stream will be processed and will act as expected, i.e. a new page will be started in the output PDF file. This can be disabled with the "--noformfeed" option which will cause all formfeed characters to be ignored.

Options may be given in any format recognised by the Getopt::Long Perl module, e.g. --name=value or --name value. Option names may be abbreviated to their shortest unique value.

If the input filename is not given, then a2pdf will expect to receive input from STDIN.

Wad2PDF examines wad files and prints an overhead picture of all levels to a PDF file.
Wad2PDF is a program that converts the levels in Doom wad files into PDF files. The result has a birds eye view of every level, with floors neatly texturized and all items in the level in their proper places.
The PDF output can be imported to graphics programs for further editing or printed out directly. You can even create wall-sized mega posters of your favorite Doom levels.
Main features:
- supports all Doom games: Ultimate Doom, Doom II, Heretic, Hexen, and Strife
- full pwad support
- creates browsable PDF with bookmarks identified by level names
- reads gl nodes both from wads and GWA files

PoDoFo library is a free, portable C++ library. PoDoFo library can parse existing PDF files and create new ones from scratch.

PoDoFo is a library to work with the PDF file format. The name comes from the first letter of PDF (Portable Document Format). A few tools to work with PDF files are already included in the PoDoFo package.

The PoDoFo library is a free, portable C++ library which includes classes to parse PDF files and modify their contents into memory. The changes can be written back to disk easily. The parser can also be used to extract information from a PDF file (for example the parser could be used in a PDF viewer).

Besides parsing PoDoFo includes also very simple classes to create your own PDF files. All classes are documented so it is easy to start writing your own application using PoDoFo.

As of now PoDoFo is only available for Unix platforms. But the code is portable C++ and a Windows version will be available soon.
