Open-source notice

RichBinder is distributed together with open-source software. Each component is governed by its own licence, and the rights that licence grants you take precedence over the RichBinder terms of service.

These rights take precedence over the terms of service

For the open-source components provided with the product, the rights that the open-source licence grants you take precedence over the other provisions of the terms of service (including Article 2, “What you may not do”), and the terms do not limit those rights.

Below is what is actually contained in the version currently distributed (1.0.22). When the version changes, this list changes with it.

Office preview engine — LibreOffice

LibreOffice 26.2.5.2
Mozilla Public License 2.0 (includes components under other licences)
Purpose
Converts Word, Excel and PowerPoint documents to PDF to build previews
Not modified
We ship The Document Foundation build exactly as it is
A separate program
Not linked with RichBinder; it runs as a separate process
Build identifier
cd7284b4cbbfeb507e630c1aac019f4157393acb

The full licence texts are in the installation folder at engine/office/license.txt · engine/office/LICENSE.html · engine/office/NOTICE, exactly as The Document Foundation distributes them.

If you have trouble downloading from the addresses above, let us know through the contact below. We will send you the same source as the version we distributed.

Hangul document support — H2Orestart · Temurin JRE

H2Orestart 0.7.13
GNU GPL v3 or later — but it differs from file to file (see ★ below)
Eclipse Temurin JRE 21.0.12+8
GNU GPL v2 with Classpath Exception
Purpose
Converts Hangul (.hwp / .hwpx) documents to PDF for viewing. The Java runtime is shipped with it because the extension requires it
Not modified
We ship them exactly as received
Separate programs
An extension that runs inside LibreOffice; it is not linked with our code

★ H2Orestart cannot be described in a single line. Most of the code in the extension is GPL v3 or later, but the registration code that comes from the LibreOffice SDK, RegistrationHandler, is LGPL 2.1. We provide both full texts — GPL v3 · LGPL 2.1. They are also shipped in the installation as licenses/GPL-3.0.txt · licenses/LGPL-2.1.txt.

The full licence text and the copyright notices of the Temurin JRE are included in the distribution itself — in the installed Hangul component they are jre/NOTICE and jre/legal/<module>/LICENSE · ASSEMBLY_EXCEPTION. We do not touch the material Eclipse Adoptium put there.

Where to get the source for the Hangul components

This is the source that corresponds exactly to what we distributed. Once a version has been distributed, we do not delete its source.

The SHA-256 of the extension file we ship (H2Orestart.oxt) is 726230215dabe450bd617f9acac52376fd76f57c77158bd03b3ef9fe0c7e64fd — so you can check that the source you received corresponds to that binary.

Written offer (GNU GPL v2, Section 3(b))

For the Temurin JRE we also give you a written offer, separate from the online availability above. ROZIN Solution offers anyone, for at least three years from the date this version was distributed, the complete corresponding machine-readable source code, for a charge no greater than the cost of physically performing source distribution. The full text is inside the installation at OPEN-SOURCE-SOURCE-OFFER.txt.

Other open source we ship

We also ship text recognition (Tesseract), barcode reading (ZXing), PDF reading (PdfPig), reading original Office files (Open XML SDK), storing the document list (SQLite) and others.
