@ -369,7 +369,7 @@ Zint allows the symbol to be bound with 'boundary bars' using the option
--bind. These bars help to prevent misreading of the symbol by corrupting a
scan if the scanning beam strays off the top or bottom of the symbol. Zint can
also put a border right around the symbol and its whitespace with the --box
option. This option is automatically selected for ITF-14 symbols.

The width of the boundary or box can be specified using the --border switch.

6. Types of Symbology
=====================
@ -1226,6 +1230,13 @@ ITF-14, also known as UPC Shipping Container Symbol or Case Code is based on
Interleaved Code 2 of 5 and requires a 13 digit numeric input (digits 0-9). One
modulo-10 check digit is added by Zint.
If no border option is specified Zint defaults to adding a bounding box with a
border width of 5. This behaviour can be overridden by using the --bind otion
(or adding BARCODE_BIND to symbol->output_options). Similarly the border width
can be overriden using --border= (or by setting symbol->border_width). If a
symbol with no border is explicitly required this can be achieved by setting
the border type to box or bind and setting the border width to 0.
