Introduction

JsBarcode is a simple way to create different types of 1d barcodes.

This is the list of supported barcodes:

• EAN (13)
• CODE128 (B)

All different types of barcodes has an own class which can be used for 2 things:

• Validating the input to see if it can be encoded
• Encode to barcode format (binary output)

To validate:

var barcode = new EAN("9780199532179");
barcode.valid(); //Result: true

To encode:

var barcode = new EAN("9780199532179");
barcode.encoded(); //Result: 1010111011000100101001....

Canvas generator

####A Html5Canvas barcode generator is included to draw the barcodes.

drawBinary(binaryString, context, options);

####Where:

• binaryString is the string that the barcode encoders generates
• context is a Html5Canvas context
• options is further options, put in a JSON object

####The default options:

{
	width:2,
	height:100,
	x:0,
	y:0,
	quietZone:10,
}

Examples

This code:

var barcode = new EAN("9780199532179");
drawBinary(barcode.encoded(), ctx); //If ctx is a defined canvas context

Will generate this image:

This code:

var barcode = new CODE128("Javascript is fun!");
drawBinary(barcode.encoded(), ctx, {width:1,height:20}); //If ctx is a defined canvas context

Will generate this image:
