Each 2D barcode type supported by Barcode Xpress has its own object type. Barcode Xpress supports the creation of QR Code, Data Matrix, and PDF417 barcodes.

• WriterQRCode

• WriterDataMatrix

• WriterPDF417

Although Barcode Xpress supports reading of Aztec, writing is not supported.

Basic Steps to Create a 2D Barcode

1. Instantiate the writer class for the barcode type you want to create.

2. Set the value you want to create.

   • BarcodeValue

   • BarcodeData

3. Call either the Create method (to create an hDib) or the CreateBitmap method (to create a System.Drawing.Bitmap) from the instanced writer class. These methods will return an image with the desired barcode.
