# The LADpdf Plugin

The LADpdf plugin has no executable code of its own. It doesn't do anything or place any overhead on your site. Its only purpose is to install the free open source DomPdf PHP library, which provides conversion from HTML documents to PDF documents. The DomPdf project appears to be active and well supported, and for our purposes, it works very well. It's very convenient for Payage to be able to produce PDF invoices.

Payage can work perfectly well without the DomPdf library, but the library is free and works well, so we suggest you install it and provide your buyers with PDF invoices.

Unfortunately we doubt if the LADpdf plugin would be accepted by the Joomla Extensions Directory because many of the .php files included do not include a GPL Licence Notice. The licence supplied with the package is as follows:

*Copyright (c) Nils Adermann, Jordi Boggiano Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.*

That seems perfectly acceptable to us, but we don't think it would be accepted by the Joomla Extensions Directory.

The DomPdf library has a complex job to do. It must parse and render the HTML, as styled by any CSS files linked from it. To achieve this, the library brings together a number of subcomponents that use various different licences, but they are all licences to use the software free of charge. We find nothing untoward in the DomPdf code or any of its subcomponents.
