.NET EAN-8 Generator - Barcode EAN-8 Introduction

EAN-8, also known as European Article Number 8, UPC-8, GTIN-8, GS1-8, EAN/UCC-8, is a linear barcode and is derived from the longer European Article Number (EAN-13) code. It was introduced for use on small packages where an EAN-13 barcode would be too large.

How to Create & Draw EAN-8 Image in ASP.NET aspx or Html Pages Without ASP.NET Barcode Controller?

Top

Under demo package, copy barcode folder and its contents to your IIS, and create a new virtual directory.
Restart IIS, navigate to http://YourDomain:Port/barcode/linear.aspx?DATA=1234567&TYPE=12.
To create barcode EAN-8 image in html or aspx pages, you can insert a image tag (img) into your page.
For example, <img src="http://YourDomain:Port/barcode/linear.aspx?DATA=1234567&TYPE=12" />
