I think the old (and still good) releases of pbmplus and xv still contain the GIF tools. If you do not mind wirting a UNIX script, you can make SANE store data in PNM format and then convert to GIF. There are scanner tools like Pixel!FX by Mentalix (www.mentalix.com) which handle GIF, but they are expensive. Best regards, Ulrich Deiters
