I use barcode Pro, can generate any code I need (but I need it at work!)
Mr Moody is correct in saying the best way to crop a barcode is to truncate it (crop upto half of the top bars - no more)... there are standards relating to barcodes (different in each country), so normally 100% or 80% EAN13 codes is reccomended (or whatever the standard is in your country)... but unless you are scanning them for you database then, other percentages may still scan!
