Morphjet — open-source compliance
Source code for Morphjet's engines
Morphjet is a proprietary desktop application. It performs conversions by invoking a number of independent open-source engine programs as bundled subprocesses (“mere aggregation”), so Morphjet's own code stays separate. We nonetheless redistribute those engine binaries, and for the copyleft-licensed ones we publish their source here.
Corresponding source
For every Morphjet build that includes a copyleft-licensed component listed below, we make its complete corresponding source code available for download here at no charge — the exact upstream version we built from, together with any Morphjet patches and the build/packaging scripts needed to reproduce our binary — under the terms of that component's license (GPL / LGPL / AGPL / MPL as applicable).
Each component links to its source below. The source stays available for as
long as we distribute the corresponding build. Each engine's full license text
also ships inside its pack (share/licenses/<engine>) and is
reproduced in the app's About screen.
