Create a 2D Barcode
 |
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 DataMatrix and PDF417 barcodes.
| Object |
Description |
| WriterDataMatrix |
The object which can write out a DataMatrix barcode. |
| WriterPDF417 |
The object which can write out a PDF417 barcode. |
|
Although Barcode Xpress supports reading of Aztec and QR Code, writing of these barcodes 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.
| Property |
Description |
| BarcodeValue |
This property gets and sets the value of the barcode to be created. |
| BarcodeData |
This property gets and sets the current barcode value as an array of bytes used only if non-ASCII text values are needed. |
- 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.
| Method |
Description |
| Create |
This method is the main method for creating barcodes. |
| CreateBitmap |
This method creates bitmap barcodes. |
