Although Quartam PDF Library is a free/open source software (F/OSS) project, giving you a lot of freedom and flexibility as to how you use it in your own projects, this doesn't mean you're free to do anything you want with it: you have to respect the GNU Affero General Public License (AGPL) version 3 or later.
You can be released from the requirements of the AGPL license by purchasing a commercial license from Quartam Software.
Buying such a license is mandatory as soon as you develop commercial activities involving Quartam PDF Library without disclosing the source code of your own applications. These activities include: offering paid services to customers as an ASP, serving PDF documents generated dynamically in a web application, shipping Quartam PDF Library with a closed source product.
Such a commercial license releases you from the requirements of the copyleft AGPL license, which include:
In addition, the commercial license releases you from the requirement not to change the PDF Producer line in the generated PDF document properties.
If you have any questions about the applications of the AGPL or commercial license, please send an email to firstname.lastname@example.org.
Now that Quartam PDF Library for LiveCode is available as open source under the terms of the GNU Affero General Public License (AGPL), you are welcome to contribute to its development.
All you need to do is download, sign and email back the Quartam Open Source Contributor Agreement so that your contributions can be incorporated into the project. Quartam Software handles the role of project custodian, taking care of versioning and distribution.
