Small and simple Code 3 of 9 Library
npm install tualo-code39Description
===========
tualo-code39 is a small and simple code 3 of 9 library written in javascript.
This library creates simple text representation of the barcode for the given string.
The function getCode(data) returns the barcode representation as string. "n" or "N" means you
have to draw a narrow bar. "w" or "W" means you have to draw a normal bar. If the letter is
in upper case you must draw a black bar. You don't need to draw the lower case letters, but
you have to skip narrow or wide bar size ahead. Based on the width of the normal (or wide)
bar's width, the narrow bar width must be the third part of that.
If the given string contains any not supported characters, an exception will be thrown.
