We've also been hard at work shipping a new release of our ImageMan.Net Twain components. V 3.10 features support for the Twain ExtImageInformation mechanism for getting specialized information such as barcode info, type, mag stripe information, endorser text and more from scanners that support it.
All your application has to do is to tell the Twain control what ExtImageInformation items you want to query and after each scanned page it will return the information from the scanner to your application.
Keep in mind that these features such as barcode recognition are generally only supported in higher end scanners such as those from Canon and Fujitsu as well as specialty scanners.
V 3.10 can be downloaded at no charge from the My Products page.
