The best of TWAIN direct is still to come. The application will be able to communicate directly with scanning devices.

The TWAIN working group, that Dynamsoft is an associate of, claims that with TWAIN direct vendor specific drivers will no longer be needed. The TWAIN standard is now evolving to the next generation, called TWAIN direct. It is good if you want to use features specific to a particular scanner model, but if you want your application’s scanning behavior to be consistent on different scanners, you need to be wary of customized code.

In most cases, users should be able to either get a free TWAIN driver, or easily find one, for their scanners – Canon, HP, Epson, Kodak, Xerox, you name it.Īlthough nearly all scanners contain a TWAIN driver that complies with the TWAIN standard (the latest version is 2.3), the implementation of each TWAIN scanner driver may vary slightly in terms of scanner setting dialog, custom capabilities, and other features. Actually TWAIN is already the de facto standard in document scanners. Nowadays TWAIN is the most commonly used protocol. The Source Manager Interface provided by TWAIN allows your application to control data sources, such as scanners and digital cameras, and acquire images, as shown in the figure below.

It has three key elements, the application software, the Source Manager software and the Data Source software. It was designed as an interface between image processing software and scanners or digital cameras. TWAIN is scanning protocol that was initially used for Microsoft Windows and Apple Macintosh operating systems, and it added Linux/Unix support since version 2.0.

However, they have some different scanner functionalities and compatibilities. TWAIN, WIA, ISIS and SANE, are all scanning drivers that support acquiring physical images from scanners and storing the digital images on a computer.

What are they all about? What are the differences between them? Which one should you choose? Can we add it?”Īfter some research about document scanning, you find out that there are several different scanning drivers used in the market: TWAIN, WIA, ISIS and SANE. You are a software developer building a website, or a content management system, or an office automation system for your customer.ĭuring development your customer contacts you and says, “I think we need to have document scanning functionality in the system.
