Using the Barcode Demos

This document describes how to use the basic features of the "LEADTOOLS Barcode Demos".

You will find the following features in the Barcode demos:

1.	The ability to save your image to any output file format supported by LEAD Technologies, Inc.
2.	Support for reading and writing different types of barcodes.
3.	The ability to save the results obtained from reading barcodes into a Log file.
4.	Support for Twain and ISIS scanning
5.	The ability to write different barcodes using different colors.

LEAD also includes two step-by-step tutorials for reading barcodes and writing a barcode using this demo. For more information on these, refer to Reading Barcodes Using the Barcode Demo and Writing Barcodes Using the Barcode Demo.

The barcode demos demonstrate the Barcode toolkit features. They let you read several barcode types from an image, or write barcodes over an image using different options.
