Printing of Bar code and Raw Data

You can use a barcode library such as LEADTOOLS to write (draw) the barcodes on an image at the server side using .NET code. (Disclaimer: I’m an employee of this library's vendor).

The following code writes a barcode on an image and saves it into a MemoryStream:

//Create white image

RasterImage bitmapImage = RasterImage.Create(400, 150, 24, 300, RasterColor.White);

//Write the barcode on the image

Leadtools.Barcode.BarcodeEngine engine = new BarcodeEngine();

BarcodeWriteOptions writeOptions = engine.Writer.GetDefaultOptions(BarcodeSymbology.Code3Of9);

string sampleData = "123-45678";

//There are many supported types, not just Code 3 of 9

engine.Writer.WriteBarcode(bitmapImage, new BarcodeData(BarcodeSymbology.Code3Of9, sampleData), writeOptions);

//Save the image to a stream

RasterCodecs codecs = new RasterCodecs();

codecs.Save(bitmapImage, memoryStream, RasterImageFormat.Png, 24);
