In order to read or write 2D barcodes, you must purchase either the 1D/2D Standard or 1D/2D Professional edition of Barcode Xpress.
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.
Although Barcode Xpress supports reading of Aztec, writing is not supported.
Basic Steps to Create a 2D Barcode
-
Instantiate the writer class for the barcode type you want to create.
-
Set the value you want to create.
-
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.
