Library for creating 1D barcodes with node.js
Barc is a barcode library for 1D barcodes rendered using node-canvas. The plan is to suport at least Code2of5, Code39 and Code128 of whitch Code2of5 and Code128 are usable. It might not be 100% to specification in all cases but it works for most applications
$ npm install barc
This library let's you define the size of the resulting image and that might lead to unreadable barcodes if you don't make enough room for it. The same goes for border and padding. If the smallest bar don't fit the resolution used then you will defenitely have issues. This will also apply if you add rotation which makes it hard for the graphics library and any printers to draw well defined lines. Try and see what fit your requirements.
var Barc =barc =fs = ;//create a 300x200 px image with the barcode 1234var buf = barc;fs;
More examples are placed in ./examples. Most produce one or more png images.
Constructor which enables you to set common options for all generated barcodes.
