I've added support for configuring appearance of the guard bars for EAN-13 to match the standard. I need the first digit to be the same size as other digits and placed on the quiet area.
EAN-8 implementation will be similar. If you approve this approach i can make the necessary changes.
Default mode (backward compatible)
New mode - first char on the quiet zone
Because we need more space to fit the first char outside of the code a margin is added to both ends of the code. This could result in smaller code as on the image below.
