The digit width sounds exactly like what I'm talking about. Digits "123456789" bar coded in a container of 60x100 pixels look very different than in a container of 150x100 pixels (see example posted at http://betweenbrain.com/lab/barcode/comparison.html). It seems like the bar codes generated from strings with more characters should be wider then those with less characters. In either case, in theory, the density or number of lines per inch should be the same.This is merely theory only based on quick tests. Keep up the good work. This is cool. Matt
