Our Post Office is complaining that the height of the bars in the Onecode barcode is too tall.
It looks like the “extendedHeight” parameter, by default set to a value of “20”, is what I’d need to adjust down to something closer to 16.5.
My question is: can I change the default value of 20 somewhere so that all new instances in new templates have a different value (16.5), so that my users don’t have to remember to change this every time?
