128 Barcode generator written on pure javascript. Produces highly optimized SVG nodes.

Barcode svg generator (Live demo)

Easy to start

After barcode.min.js is downloaded and connected to your html5 page, call:

var
svgNode = BARCode('Hello World!');

Playground

BARCode({

     msg  : '128 Code'
    ,dim  : [ 286, 80 ]
    ,pad  : [  20, 16 ] /* sample 1: normal orientation */ 

});

BARCode({

     msg  : '128 Code'
    ,dim  : [ 286, 80 ]
    ,pad  : [ 266, 16 ] /* sample 2: vertical flip */ 

});

BARCode({

     msg  : 'vertical'
    ,dim  : [ 80, 286 ]
    ,pad  : [ 16,  20 ] /* sample 3: vertical orientation */ 

});

BARCode({

     msg  : 'vertical'
    ,dim  : [ 80, 286 ]
    ,pad  : [ 16, 266 ] /* sample 4: horizontal flip */ 

});

All available options:

BARCode({

     msg  :  message
    ,dim  : [ width, height ]
    ,pad  : [ padding-x, padding-y ]
    ,pal  : [ color, background-color ]

});

If something is lost or wrong it will fall back to default values and warn you in console, the picture will turn red:

Options

• msg - barcode message string, obviously, this is mandatory parameter

• dim - is array of [ width, height ] in pixels, default value is: [ 320, 80 ]. Set [ 0, 80 ] and width will depend on the length of the horizontal generated barcode. Set [ 80, 0 ] and height will depend on the length of the vertical generated barcode.

• pad - is array of [ padding-x, padding-y ] in pixels, default values is [ 20, 16 ]. Set [ 0, 0 ] to discard padding. If (any) padding value is greater than relative dimension value then barcode will be rotated by 180 degrees respectively.

• pal - is array of [ color, background-color ] strings that represent hex color codes, default value is [ '#000' ] along with transparent background. Set ['#000','#fff'] to make background opaque.
