Numbers play an integral role in our everyday life. For example, numbers on the salary slip, numbers on our exam result sheet, and number on our medical reports describing some health statistics are crucial to us. Any faulty modification in these numbers can lead to dreadful circumstances. One such incident took place when the news broke out that Xerox Scanners and Copiers modify the number of the documents being scanned or copied. The issue is [...]

A lot of our customers asking us about a way to acquire images from a scanner and other imaging devices. There are 2 ways to acquire an image in Windows: via TWAIN interface (used since 1992); via WIA (currently is recommended by Microsoft over TWAIN/STI because of better user experience) To acquire images using TWAIN we have an open-source SDK called Bytescout Scan SDK which is available for free download at http://bytescoutscansdk.codeplex.com/ Scan SDK is free for [...]
