hello all,
I had a problem with barcode, that upc in .eps would result with cropped
(out of bbox) rightmost digit. Since I'm using Debian I filed a bug+patch
as below.
I'm attaching patch here as well, in case Debian pkg maintainer is
busy/away, so interested people can take a look earlier.
Pls see attached a web interface I hacked up for my needs - fron-end is
in Italian (guess why ;) but changing it for other languages is trivial.
HTH - feel free to stuff it in contrib/.

Subject: [PATCH] Re:barcode: wrong image size w/ -E -g ...
ok, fixed for my perusal - no thorough testing though, just a round for all
supported codes.
The problem was for upc only, as this has the rightmost digit external to
the bars (like first).
Should work for any other (future) case though, as the patch simply takes
into account the width of last digit to print, if BARCODE_NO_ASCII is unset.
