Generate linear barcodes in web-based applications with the ASP.NET 1D Barcode Generator. Insert a call to an ASPX script file, located on a local or hosted ASP.NET enabled web server, in any application where barcodes are needed. Each symbology has its own ASPX file in pure ASPX source code form that can be modified with different parameters. The default output of the barcode is a BMP 1 bit size image, smaller than other vendors in comparison, where the average size of the image is less than 2kb. PNG and JPG images are available options if needed. Barcodes supported are Code 39, Code 128, GS1-128, GS1 DataBar, EAN13, Interleaved 2 of 5, MSI Plessey, Planet, Postnet, UPCA and Intelligent Mail IMb.
