Reference documentation of Toon Boom file formats?

Wondering if there’s online reference quality documentation for the Toon Boom file formats (.tvg, .plt)?

Looking at whether it’s feasible to add native export of tvg to packages like Inkscape (

There’s no online documentation for the file formats. They are proprietary file formats that only we can write, there’s no way for other programs to write a tvg file or a plt file.

What we might be able to look at doing is supporting svg file format. I could submit this as a feature request.
