Import a GDTF file (General Device Type Format) containing a fixture type description. GDTF provides a fixture's digital footprint. Visit [https://gdtf-share.com](https://gdtf-share.com/) for more information.

The GDTF file is a zip file containing:

- Description
- Geometry data
- Gobo images

For a detailed description of GDTF, see the DIN specification 15800:2022 (<https://www.beuth.de/de/technische-regel/din-spec-15800/349717520>).
