[Gimp-user] Vector or line based file format

[Alan Wolfe]

Hey everyone,

Does anyone know of any good open file format that is saved as line data?

Hopefully something that can be used across different programs out there.

Is there such a thing?  I'm on a small project looking to outsource
some graphics (we already have the artists picked out) but our game
uses line data only so finding a good way for artists to make us art
is a challenge (:

Thanks for any info!
Alan
