That doesn't sound so bad then. If we choose to make this official, then we should offer a kind of "compatibility test suite" of ORA files for developers to check against, as this case is easily overlooked. > On that point, I am not too concern about those breakage, I think that > OpenRaster goal is interoperability, but if that goal can only be achieved in > a year, it's not a big problem for me (as long as we communicate on this).

There is a GIMP plugin being written, and I recently got mail from someone who wants to try implementing full-screen previews in a file browser (gloobus). I hope we can make only one breakage, and after that applications should be able to add as much compatibility as they think is still required when saving. bye, Martin _______________________________________________ CREATE mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/create
