Games::Go::Dg2PDF is a Perl extension to convert Games::Go::Diagrams to PDF (Portable Document Format).

SYNOPSIS

use Games::Go::Dg2PDF
my $dg2pdf = B convertDiagram($diagram);

A Games::Go::Dg2PDF object converts a Games::Go::Diagram object into a PDF file.

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.

Panda is a PDF generation API written in C.
The Panda PDF Generator is intended to make PDFs on the fly for the Web, but may be used to generate any PDF document you want.
Enhancements:
- As you may already be aware, the most important change in 0.5.4 is that the library is now available under the terms of either the GPL or LGPL (your choice). In order to accomplish this, the TDB code was removed, and either Enlightenment DB or Berkeley DB (version 4) must be linked to in its place.
- Other changes include the addition of link annotations (internal and external), pkg-config support, and an RPM. The main point of this release, however, was the licensing issue.
