Your right! It's actually the transfig package as a whole which appears to have no support for the generation of gif. If you look at the source code you will find there is support for reading gifs, but none for generating them. gif is a proprietry non-free format. You have to pay a license fee if you want to distribute applications which generate gifs. You can however distribute code which reads gifs for free. The alternatives are to use png or jpeg formats. I can't remember all the details, but all of this is due to some rather famous legal moves initiated a few years ago by a large US corporation. The PNG format was developed as a direct response. By not using gifs you are indirectly promoting the use of open standards/protocols/formats. Some others may have a clearer recollection of the details. Regards ...
